Speaker 1 (00:03):
Welcome to Master of Science with host Professor James McCanny.
The good professor's career spans fifty years as a university teacher, scientist,
and engineer. Each week, he will explore the rapidly changing
world of science as many long held theories are crumbling
under the weight of new data. He will cover the
(00:23):
fields of geology, archaeology, meteorology, oceanography, space science, astronomy, cosmology,
biological evolution, virology, energy, mathematics, and war. So please welcome
the host of Master of Science, James McCanny.
Speaker 2 (00:52):
Good evening, everybody, and welcome again. Tonight, I'm going to
finally talk about the BET's limit of it and promising
this for quite a few weeks, and all of these
other incidental items came up, so my show got sidetracked.
Well those who are important issues, and so tonight I'm
going to talk about the BET's limit. So you might
(01:14):
be wondering what in the world is the BET's limit. Well,
it's something that affects all of you every day. It's
used in the used incorrectly, i should say, in the
wind energy industry. And so I'm going to go through
the physics of this and so this is going to
be a little bit technical, but I think that's what
(01:34):
people are looking for, not just glossing over a topic,
but going into depth and talking about it in detail.
And just to remind you that, tell your friends about
this show, tell your family, tell your friends, because we're
growing in numbers. This show only started last July and
is doing very well. So the reason people listen to me,
(02:00):
and this goes back fifty years as I have a
lot of experience. My background extends into places where most
people have never been, and I've been at tier levels
of science. I've explained before in the show that there
are various tiers of science. Tier one science is what
I call military science. It's the science that you never
(02:22):
see or hear about. It's not published in peer review journals,
and it's what is kept at the very highest levels
in government and in the secret agencies. I call it
military science. I've also worked around tier two people, which
would be like universities, where university professors published in peer
(02:45):
review journals, they get federal grants, etc. I don't take
federal money. I've never taken federal money to do my research.
I've always funded it myself. And so by the way,
I'm a degree physicist. I've an advanced degree, master's degree
in nuclear and solid state physics, and saw a very
(03:07):
good education and not getting a PhD is probably one
of the best things I ever did because it allowed
me to work in so many different fields. I worked
in the telecommunications industry for twenty five years in high
security locations. I have peer reviewed, public published papers in astrophysics,
(03:30):
space science, mathematics journals, and I've made a lot of
major discoveries in these fields. When I talk about something,
it's because it's because I've been there myself. It's not
because I read it on somebody's web page or read
it in a book someplace. When I tell you something,
(03:50):
it's because I've been there. I've done it myself, bought
the T shirt, as they say. I've been at many,
many international sciences conferences on other more esoteric topics. I've
been an invited speaker at places like Los Alamos National Laboratory,
talking about and really instructing the people there, high level astrophysicists,
(04:15):
plasma physicists on the true nature of the Solar system.
This is some of my work. The plasma discharge comet model,
the electrical nature of the solar system, the fusion based
stars and what makes them tick, etc. And I've also
been guests on all of the top radio shows, all
(04:36):
of the top platforms, and my background goes back fifty years.
So when I talk to you, I have a world
of experience and it's not something you're gonna find anyplace else.
So this is unlike any other podcast you're gonna see.
This is going to be true educational courses and unless,
as tonight's show will bear out, very high level discoveries
(05:03):
and criticism a lot of times of the science and
engineering industries. So anyway, tonight I'm going to be talking
about the BET's limit. Now what's the BET's limit and
what does it have to do with you? Well, the
wind energy industry is one of the most failed industries
(05:24):
on the planet. It gets huge, absolutely mammoth government incentives
and benefits, yet it is failing. How could it in
a world where energy is king the number one product
in the world is energy, How could a product in
the energy industry fail? It's the reason is because they
(05:47):
don't work. And so what Twenty five years ago I
sat down and after doing a study for a Midwest
company that was involved in biophy. I made a major
study of the electrical generation industry and found that it
was horrifically inefficient. And at the end of my study
(06:11):
for this company, they asked me to do a review
on three blade wind turbines and solar panels, which were
just beginning to crescendo at that time, the early two thousands,
and so the study I went through and I analyzed
these and I said, this stuff doesn't work. It'll never work,
(06:32):
it will never In My criteria was will it solve
the world energy problem or even make a dent in it?
And the answer was no. So I went about writing
a functional specification and I came up with what is
now a patented energy device, multiple patents on what I
call the wing generator. And tonight I'm going to talk
(06:52):
about the ability to extract energy from the wind and
how the wind industry. This is the core concept here
because it was on my November fifth and twelfth shows
last year on this television show and then also my
(07:13):
radio show. I have a radio show that's been going
on for twenty five years WWCR Nashville, Tennessee. But on
the November fifth and twenty and twelfth show, I talked
about the wing generator, so I'm not going to repeat that.
But what I'm going to do is discuss this concept
called the BET's limit. So theoretically, if you're in the industry,
(07:38):
what do you want to know? You want to know
how much energy can we extract out of this fluid
we call the wind. It's called a Newtonian fluid. That's
the technical term. So water, moving water or moving air
would be a technical term for all categorized under what
we call Newtonian fluids. Because they interact, they have mass,
(08:02):
and they can cause things to move. Therefore, you can
extract energy and cause turn that into various types of energy,
and specifically electrical energy and so or you could use
it to compress air or do other things. But to
begin with, what I'm going to do is to find
the BET's limit and give you an idea of how
(08:26):
this is being used incorrectly in the wind energy industry.
The basic components of the BET's limit is, Okay, you
have a column of air moving, and strictly the BET's
limit does not deal with air. So anyway, the first
rule of the BET's limit is that it deals only
(08:49):
with non compressible fluids. This is a big one. What
is a noncompressible fluid, well, water, hydraulic fluid, oil, mostly
liquids you would consider as non compressible. In other words,
you could build a hydraulic system out of them. And
as you put a hydraulic ram on something, the fluid
(09:11):
in those tubes and chambers is not going to compress
at least not very much. Air, on the other hand,
is a compressible fluid. That's why we use it in tires.
For example. You would not fill your tire with water.
That would not work very well. You fill it with air.
(09:33):
And why do you fill it with air is because
when you hit a bump, the tire compresses, the air compresses,
it acts like a shock absorber. And so that's the
entire principle of you would not use air in like
I say, in a hydraulic system. You simply would not
do that because it is a compressible fluid. And that
(09:56):
has everything to do with something called aerodynamic lift, which
I'll be talking about. Also. It comes into play because
when you start extracting energy from the wind, the same
thing happens when you fly an airplane. The wings are there,
and what's going on there what causes the wings to
create lift, and it's due to the fact that air
(10:17):
is a compressible Newtonian fluid. Okay, so number one, the
BET's limit only deals with non compressible fluids. Water. And
one of the best examples of the use of the
BET's limit is in a hydro dam. You have a
big body of water, you put a dam there, and
(10:40):
then you let the water spill over into these spillways,
and then it goes down into a tube literally a tube,
and it comes down into an impeller. We'll be talking
about the design of these impellers and the kinetic energy. Now,
this is the second part of the BET's limit. It's
at energy transfer. In other words, movement. Kinetic energy is
(11:04):
the energy of movement, and so if you're going to
extract energy from a kinetic energy system, what you're doing
is you got to slow that down. You have to
slow down that fluid. In this case, in a hydro dam,
you have water rushing down a tube and it as
(11:25):
you take energy out of it, there's a turbine at
the bottom that's spinning, and as you take energy out
of that fluid, it's going to slow down. So what happens.
The flange on this turbine head has to bend outwards.
In other words, that as the water slows down, the
(11:45):
tube that it's moving in has to get bigger to
accommodate the slower flow. If you don't do that, then
it's going to create a back pressure and slow down
the water coming down because it's a non compressible fluid. Okay.
So the BET's limit refers to the kinetic energy. How
(12:05):
much energy can you extract from a non compressible bluid? Okay,
And so there's an actual number it comes out. It's
a ratio. It's fifty nine point twenty four or something
like that percent of the energy the kinetic energy in
the tube you can extract. And this is kind of well,
(12:26):
a few things are going on here as you slow
down this column of moving kinetic material water in this case,
as you slow it down, Okay, you can slow it
down so much, but if you slow it down completely,
then the system backs up and it doesn't work anymore.
If you don't slow it down enough, then the water
(12:47):
just goes rushing through and you're not optimizing the energy extraction.
The kinetic energy extraction from that column of water. So
there's a balance there, and that balance turns out to
be theoretically nine point two four percent of the kinetic
energy in this column of water is obtainable as energy.
(13:09):
And then you connect that up to an electric turbine
and then it drives it creates electricity, three phase electricity.
You put it into a step up transformer, and then
you put that out over the high voltage lines which
transfers across the country, and then it is stepped down
through other transformers a series of transformers into local power,
(13:32):
which ultimately arrives at your business or house to use
as useful electricity. So that's the electrical grid system, but
powered by hydro dam and so anyway, the best's limit
is number one for a non compressible fluid, which is water.
(13:53):
Number two. It's a kinetic energy transfer. So you're taking
energy connecticut energy, the energy of motion, converting it into
energy of rotation rotational energy, which then drives a turbine,
which creates electricity which sends out and then you turn
on your light bulber, make your toast. Okay, So that's
(14:15):
the beginning. Now a number of a number of years
ago I gave a lecture on this and some of
those things. It just blows out so naturally and so concise.
So I'm going to actually delve into that lecture and
play it here, and then I'm going to come back
(14:36):
and talk about wind energy. But let me just preface this,
so I'll be repeating myself a little bit, but I
want to preface this by talking about the wind energy industry.
Whenever you talk to somebody in the wind energy industry
and you talk about efficiency, number of problems occur When
they quote in the newspaper that, oh, they're putting in
(14:57):
fifty or one hundred or so many three blade wind
turbines and it'll be enough energy to power seventy thousand homes.
What they're doing there is a lie, because what they're
doing is they're saying if these three blade wind turbines
were able to run at full capacity all the time,
(15:17):
they could power seventy thousand homes. But that's not what's
going to happen, because the wind doesn't blow all the time,
does it, And when it does blow, you only get
a bit about maybe maximum twenty percent of the energy
from those three blade wind turbines if they're not broken.
And so which most of them are today. But anyway,
(15:38):
that's another story. So anyway, the problem is that they
overquote what these things, and then the city councilor the
county council, or the state government or whoever says, oh,
look at all the energy these are going to produce
based on a lie. Okay, but let's get back to
the crux of the issue here with the BET's limit
(16:01):
is based on the movement of air, and air is
a compressible fluid. So right off the bat, wind energy
doesn't qualify for the BET's limit. Secondly, if you're going
to try to qualify for the BET's limit, you better
have something that traps the energy in that entire column
(16:22):
of air. Those three skinny little sticks that they call
turbine blades sticking up in the air, about ninety five
percent of the wind blows right through them. They don't work.
They don't trap the air. They don't trap the energy
in the wind. And if I have time at the
end of the show, I'm going to go through a
whole laundry list of problems with that system with a
(16:44):
three blade wind energy system. And third of all, when
you're extracting energy from a kinetic energy system like in
a hydro dam turbine, you can use a little bit
of hydro hydrodynamic lift, but primarily it's simply brute force.
(17:04):
You're putting the water down through a turbine blade. It
has a cut to it and anyway you can see
the pictures that I'm showing, it's going to take that
kinetic energy in the forward motion. The momentum of that
column of water is going to turn the turbine blade,
(17:27):
which is going to turn the electricity, and you're extracting
kinetic energies. Whereas in the three blade wind turbine, the
aerodynamic lift. They do have the shape of a propeller,
but the problem is they're perpendicular to the rotational direction,
so they actually work against the tower that they're on,
(17:48):
and they provide very little lift. It's like having a
flat board out there. So at any rate, I'm going
to play this previous discussion on the BET's limit, a
number of years ago lecture that I gave, and then
I'll come back and discuss this. The next topic I
(18:11):
want to talk about is called the bets law. Now,
this is going to be my science topic for the night,
The main science topic. Okay, let us imagine Now where
this is going is there's an industry standard that's been
used for literally one hundred years in the wind energy industry.
(18:33):
It is that old people trying to make devices that
work in the wind, and I finally invented the thing
that really works based on aerodynamic principles, et cetera. And
part of the problem has been people have been marching
down the wrong road because of misconceptions. Okay, so anyway,
(18:54):
this is going to be a little bit of an
insight into what we call kinetic kinetic energy transfer kinetic
energy transfer, and I'm going to talk about airplanes and
I'm going to talk about wind energy systems, and so
the whole idea here is to look at what a
(19:14):
kinetic energy transfer is and basically the Bets law, if
you look it up on the Internet or look it
up in an engineering manual or whatever, it was discovered,
and what it amounts to is the question is if
you're trying to extract energy from a column of air
or column of water, is in the case of a
(19:36):
hydro dam, how much energy can you actually extract from
the system? Is there a maximum amount? And so there's
a believe and I've talked to engineers before and the
first thing they do is they go, well, here's the
kinetic energy in the system. And so the belief is
that the only energy in the system is kinetic energy.
(20:00):
That's wrong. This is badly wrong. And let me just
put it this way. If that were true, airplanes couldn't fly.
And I'm going to explain that to you right now.
Imagine you have a model airplane in a wind tunnel.
We're gonna do all of this in a wind tunnel
because it's a little easier to understand. You have a
tunnel of air, there's a big fan at the end
(20:23):
of the tunnel which is creating the wind, and then
you put your airplane or your wind generator or whatever
in this wind tunnel. So that's the easiest way to
explain this. So we have a kind of a standardized
test facility to and this is going to be what
we call a Gadonkan experiment, a thought experiment. It's something
(20:45):
you have to conceive of in your mind. Okay, So
now take an airplane, put it in the wind tunnel.
You mounted on a sturdy post, and there's the airplane
all by itself, and you're gonna be able to measure
the on the airplane based on the wind coming into
the airplane on the nose side of the airplane and
(21:08):
hitting the wings. And then you have the drag on
a fuselage and on the engines, et cetera. And what
is the lift? How much lift are you going to
get out of this airplane? And the first thing we're
going to do on the airplane is we're going to
put flat boards. Just flat boards, Okay, And now imagine
(21:28):
here's another thing. If you're a skier, say a water
skier and or even a snow skier, you have two
boards on your feet. There's nothing aerodynamic about them. They're
just boards. They have a little flip up at the
front end, but they're just boards. And so like, if
you get behind a powerboat and you're on your water
skis and the boat gets up to speed, what are
(21:51):
you doing. You're pushing the boards against the medium, which
is the water, and if you go fast enough, the
boards cover enough waters area where it provides enough lift
to keep you up. If the boat goes too slow,
you start sinking down into the water and you start
(22:11):
having a tremendous amount of drag, but you can still
kind of keep up but anyway, these are flatboards. So
now imagine on your airplane in the wind tunnel, you
have flatboards on the wings. Okay, Now you turn on
the fan on the wind tunnel, and the question is
(22:33):
how much energy is lost, how much drag is there,
and therefore, how much engine power do you have to
supply to make that airplane go forward and fly. It's
because the airplane weighs so much, So it's a simple
vector equation. The weight of the plane is down, the
(22:53):
lift of the wings is up. The pressure of the
wind coming in the front side that causes drag. So
that causes a vector of drag. And now you have
to put the engines on there, and they're going to
push this thing forward. If you took it out in
a real world situation, and then if you put enough
(23:15):
power behind the engines in the engines, therefore this thing
would be able to fly. Okay, So it's a very
There's four vectors. There's the lift of the wings, there's
the weight of the airplane going down, there's the drag
of the airplane, and then there's the force of the engines.
There's four vectors here. Okay, So now we're going to
turn the fan on in the wind tunnel, and all
(23:37):
we have on the wings are flat boards, and this
is the whole point of a kinetic energy transfer. Now
you're going to tip the plane up or the wings up,
so that the wind comes in. It's the underside of
the flatboard wing. The wind is deflected down, and therefore
that causes an upward force on the flat board. That
(24:00):
is a pure kinetic energy transfer. Because the wind coming
in hits the wing, bounces down, which makes the wing
go up. And now if you had an airplane like this,
the airline industry would be in rough shape because what
(24:20):
you have out there is a wing, and it's called
a wing like a bird's wing, and it has an
aerodynamic shape. So now we're going to replace our boards,
which is a true kinetic energy transfer. There's no lift,
there's no aerodynamic lift on the flatboard. It's just a board.
And so when the wind comes in, it hits the wing,
(24:41):
the wind goes down. It's deflected down by the flat wing,
and that creates lift, and that's a kinetic energy transfer.
And there's a limit to how much you're going to
get out of that, because there's another issue. There's a
lot of drag that's being caused by that wind wing.
As the wind hits it, some is being deflected down
(25:05):
But remember that wind is coming into the front side,
the nose side of the airplane, and so it's also
pushing the wing backwards. There's two vectors that come off
the wind hitting that flat board. One is pushing it
backwards and one is where the wind is being deflected downwards,
(25:25):
and that makes the wing go up. This is the
flatboard wing. Now let's replace the flatboard wing with an
aerodynamic wing that has an airfoil. What is the difference?
And it turns out I'll give you the answer before
we start here. It's about a tenfold increase in force
(25:47):
in lift force, okay, and this is how it happens.
Let me use another example here. Now, let's take an
automobile and let's take a semitrailer trucking down the highway.
The truck is going down the highway and the back
of that truck is flat. So what happens the faster
(26:08):
the truck goes, the air comes around the side of
the truck and then it tries to get back and
flow around the backside of the truck. But what happens
because air is a compressible medium, it's not a perfect fluid.
It comes around and it leaves a vacuum in the
back of the truck. So some semi trucks that go
(26:31):
across country you will see kind of a flange that
comes around the back of the truck. And what that
does is it allows the airflow to come around the truck,
and it doesn't it reduces that vacuum at the back
of the truck. So literally the faster the truck goes,
the more vacuum that's being created or the car, and
(26:52):
that's literally sucking the truck backwards. There's a vacuum behind
the truck. And the same thing happens for a car.
So people talk, for example, about putting a new carburetor
onto a car that you know you get two hundred
miles out of the carburetor. Well, it's not going to
happen because the car design itself will not allow that
(27:13):
level of efficiency because what's happening is in a say
an SUV that has that square back. The fact, if
you're going seventy seventy five miles down the highway, miles
seventy miles per hour down the highway, then the wind
is creating a vacuum back there in that flat back
of the vehicle and sucking it backwards. Okay, now here's
(27:39):
what happens with a wing, an aerodynamic wing. We put
the airplane back in the wind tunnel. We put on
the fan, the same amount of fan wind speed that's
coming into the air craft into the aircraft, and so
it's the exact same scenario as before, the same wind speed,
et cetera. Except the only difference is now you have
(28:00):
airfoil wings on the airplane, not flat boards. What is
the difference. You're still going to have that wing a
little bit of an angle, but not as much as
the flat board. And what happens is some of the
wind is going to hit the underside of the wing.
It's going to cause pressure on the underside of the wing.
But the thing that's really causing the lift is the
(28:22):
wind that comes over the front side of the wing.
And if you look at a well designed wing, it's round,
it's a perfect circle on the front edge. So the
wind comes in, the wind splits. Some of it goes
up above and some of it goes down below. And
so the part that goes below there's a little bit
of an angle to the wing, and so the wind
(28:44):
is hitting the bottom of the wing and causing more
pressure than if you had a dead air situation. But
what really happens is some of that air goes over
the top side of the wing, and just like in
the back side of the semi trailer, it can't get
down to the wing. The faster and faster you go
(29:05):
relative to the wind, the wind cannot get back down
on the top of the wing that fast, and so
it creates a vacuum. There's another way of looking at this.
Most people look at it in terms of what is
known as the Bernouilli principle. But what's really happening here
is you're creating a vacuum on the upper side of
the wing. In that vacuum is literally what lifts the
(29:28):
vehicle up. The airplane and you'll see some airplanes now
have a little flip up at the end of the wing.
And that is something that the Right brothers discovered when
they very first had an airplane. They went out in
the field and they calculated how much lift they should
get off of a wing, and they had kind of
a square shaped wing, and they went out and they
(29:52):
really couldn't get enough lift off of this, and they
couldn't figure out why. So they went back and they
actually created the very first wind tunnel and they put
their model of their airplane into the wind tunnel, and
then they tried different configurations of wings, and they did
something very interesting. They did a smoke trailing, and what
they discovered is that the underside of the wing had
(30:15):
higher pressure, the upper side of the wing had less pressure,
but the wind was coming around the edge of the wing,
the tip of the wing, over the top of the
wing and ruining the vacuum on the top of the wing.
So they figured out that the longer wing worked better.
Even though you had exactly the same surface area. You
(30:37):
had exactly the same amount of area of your wing,
the long wing worked better, and they didn't really realize.
Now there's let's take a look at a vulture or
a condor, or an eagle, a soaring bird. Look at
any of them in flight, and you'll see at the
end of their wings they have a group of feathers
(31:00):
that sticks straight out from the end of their wings
and they're flipped up. So what happens as the air
from the underside of the wing comes up those feathers
redirect the wind up and away from the top side
of the wing, and that gives you a better vacuum.
These are the principles of aerodynamics, and so I could
(31:22):
go on and on about this topic. But the point
here is what I've been trying to instruct you with
is the difference between an airfoil and a kinetic energy
transfer something that is This is basic one oh one physics,
or at least aerodynamics one oh one physics. The bets
(31:45):
law is something that has been used in the wind
industry to give an upper limit of the amount of
energy that is in a column of wind. And let
me give you a perfect example of the u use
of the BET's law. Now, the BET's law has some assumptions.
When you go into the calculations and the theoretical construction
(32:08):
of the BET's law, what happens is, let's take a
hydro dam. You have a big lake and then you
have basically a funnel where the water pours over it's
near the dam. You have a dam, then it drops
down and down at the bottom of the dam. In
(32:28):
a housing, you have tubes where the water comes down
the tube. So you get a lot of pressure because
of the water pressure coming down this tube. It's a
constant diameter tube and it comes into a basically a
propeller blade type of system, but it's different than a
regular propeller blade. It looks like a series of flanges.
(32:52):
And what happens is as the water enters this propeller
which is connected to the electric generator by the way,
as the water comes down into this generator, the water
enters and as you extract kinetic energy out of the
water column, the water slows down because you have extracted
(33:14):
kinetic energy that's going into spinning the blade. Now, what
happens as the water slows down if you didn't make
the flange expand and get bigger, in other words, the
propeller blades go outwards and give in there it moves
in a bigger diameter tube because the water's now moving slower.
(33:37):
If you did not do that, the slower water would
back up and create a back pressure up the tube,
and it would limit the amount of energy you could
get out of the water. So this is the design
of a perfectly constructed example of the BET's limit. Because
water is a non compressible fluid, you can use water
(33:59):
for example, in a hydraulic ram. You could use it
in place of hydraulic fluids. What is a hydraulic fluid?
It's a non compressible medium. Now, let me ask you
a question, all you engineers and even third graders out there,
would you use air in a hydraulic system? And a
(34:22):
hydraulic system is where you have a hydraulic ram. There's
a piston inside of a big long tube, and then
you have a little motor there or sometimes a pretty
big motor that's driving pressure into that hydraulic fluid into
the columninet makes the arm go out, and you use
(34:42):
these on big road equipment, etc. And so anyway, the
hydraulic fluid in that hydraulic system is a non compressible medium.
The question is would you use air in that system
in place of hydraulic fluid? And the answer is no.
And the reason is because error is a compressible medium.
(35:07):
If you tried to pump air into that system, it
wouldn't work very well at all because air is a
compressible medium. So the very first thing about the BET's
limit is that air is a compressible medium. It doesn't apply.
It does not apply to aerodynamic systems. The BET's limit
(35:30):
refers to systems that are kinetic energy and they have
the fluid that's used the Newtonia. They're called Newtonian fluid.
So any fluid is a Newtonian fluid, but it would
have to be like water or hydraulic fluid or oil
or something that is non compressible to work with the
(35:54):
BET's limit. So they've been completely using this incorrectly. And
I had a little run in with a let's say,
somebody high up in the wind energy world this past
week and immediately started spouting off about the betslimit. And
that's why I'm talking about this because everybody a general
(36:18):
Electric or Semens or Vesta, or in the government, or
people dealing with government contracts dealing with energy, have this
belief in their brain that the maximum amount of energy
you can get out of a wind system is limited
by the betslimit. And there's also another issue that if
(36:39):
you have a system where you're extracting kinetic energy out
of a column fluid moving column of fluid, then necessarily
that column has to slow down because you're extracting energy
from it. It's kinetic energy. Kinetic energy is energy of motion,
(37:00):
and the equation for that is one half MV squared.
So the faster it's going, the bigger velocity the square
of the velocity times the mass. I mean, that just
gives you the kinetic energy. And if you take some
energy out of there, you're going to reduce the mass
is the same, so you're going to reduce the velocity.
(37:23):
And therefore that's how you extract energy out of the system.
But you can't take all of the energy out because
the water would stop and it would back up your
system and it wouldn't work anymore. So the BET's limits
comes up with a number that's fifty nine percent. I
believe it's around fifty nine percent. Anyway, that's the maximumount
(37:43):
of energy you can extract out of a kinetic energy system.
But wind it does not apply because, as I talked
about in the airplane example, a pure kinetic energy airplane
would be a flat board. An aerodynamic airplane wing would
(38:03):
be an aerodynamic shape. And the reason you're getting lift
out of this, you're not extracting energy out of the
wind to create the lift. What's happening is the faster
you go with your wing relative to the air, the
more vacuum you're creating on the top side of the wing,
and the only drag is that little bit of drag
(38:23):
on the front of the wing. So it's not the
drag on the front of the wing is not what's
causing the lift. It's kind of a it's a cost,
but it's not the energy that's used to lift the wing.
It's the fact that there's you're creating a vacuum on
the upper side of the wing, and that's pulling the
(38:44):
wing up. And that's why a very small wing, a
relatively small wing, can lift one hundred thousand pounds jet airliner.
And that's why you have to start going down a
runway when you take off. You take off, airplane starts
taxing down a runway and all of a sudden, the
vacuum on the upper side of those wings. You can
(39:05):
see the wings starting to lift up, and pretty soon
they lift up the entire airplane and away it goes
off into the blue horizon, as they call it. But
that's because it's not because of the BET's limit. An
airplane that had a physical kinetic energy transfer only you
(39:26):
would have to have engines ten times as big as
they are. They would use ten times as much fuel,
and they would fly one tenth the distance, you would
not have airplanes flying around the globe. Okay, So anyway,
the very important point here is that aerodynamic lift gives
you a big advantage when you're creating aerodynamic systems. So
(39:52):
when I created the wing generator, I knew this, and
it's so incredible to when you intererd to people, the
first thing out of all of their mouths is, well,
you have a thing called the BET's limit. These people
are ignorant morons. They've been It's so typical. It's so
(40:15):
typical where you have engineering schools, and it's let me
use another example. People that believe hurricanes are caused by
warm water, and it's universally believed in the meteorol meteorological world,
in the universities wherever you go, and you can do
(40:38):
a very simple calculation. As a hurricane passes over the ocean,
there's a slight drop in temperature of the surface of
the ocean and it's down to maybe a few inches
in the surface water of the ocean, not very deep.
But what's going on with the wind of the hurricane
(40:59):
is blowing over the surface of the water and it
evaporates the water. That's where all of the water comes
in the hurricane. It's being evaporated off the surface of
the ocean. And if you look at the amount of
water that's in the hurricane and you calculate the latent
heat of evaporation that's a chemical term. What you will
(41:20):
find is that the amount of energy loss due to
that slight temperature change as the hurricane passes over the
warm water is just equal to the amount of water
in the hurricane itself. So that's where it's coming from.
It doesn't power the hurricane. Good grief. Let me give
(41:41):
you another example, a very simple example. You see a
car going down the road, and it's the first time
you ever see a car going down the road, and
you ask a person what's making this cargo down the road?
And you see that exhaust pipe coming out of the
back of the car. So you think, well, this must
be a rocket powered car because there's exhaust coming out
(42:03):
of the back of the car, out of the exhaust tube,
and it's going one way and the car's going the
other way. So it must be that the exhaust coming
out the exhaust pipe at the tail end of the
car is making the car don't go down the road,
but you make a quick calculation and you realize that
the amount of vapor and the speed that's coming out,
and you look at the mass of the car and
(42:24):
you go, well, this could not possibly be what's causing
the car to go down the road. There must be
something else going on here. And then you would lift
up the hood and you go, well, gee, there's a
big internal combustion engine in here with a transmission and
a lot of loss due to all of the inefficiencies
in the engine, and it's burning some kind of high
(42:46):
combustible fuel called gasoline, and that's what's making the cargo
down the road. It's the same thing over and over
and over again. Let me give another example. How about
climate change, one of our favorite topics. And imagine that
(43:06):
somebody believes that the greenhouse effect is going to raise
the global temperature by point one degrees in the next
twenty years due to greenhouse gas emissions. Okay, well, okay,
let's talk about that. Let's look at an automobile again,
or how about a nuclear power plant or a coal
(43:29):
fired power plant for example, a little better example. So
let's look at the coal fired power plant. It is
burning a coal in about eighty percent of the heat
that's generated goes right up into the atmosphere right now.
And then there's some carbon dioxide that's given off from
the burning, and that carbon dioxide goes into the air.
(43:51):
And the theory is that over a ten to twenty
year period that carbon dioxide in the air is going
to cause an trap of heat into the atmosphere and
overall it's going to raise the Earth's atmospheric temperature by
zero point one percent. Well, it's about one kazillionth of
the amount of heat that's going directly into the atmosphere
(44:14):
right now. So once again, science has nothing to do
with the emotional contribution that people have towards climate change.
Or how about the Sun which provides us minute to
minute energy, and if remember at night. Let's talk about
(44:34):
this as the night time comes no matter where you
are in the world, except if you're in the above
the Arctic circle in the summertime, then you have twenty
four hours sun. But the rest of us, poor people
that live sub Arctic circle zones, you have daytime and
then you have nighttime. Well, what happens when nighttime comes,
(44:56):
The temperature drops. The temperature goes down, and it might
be a twenty degree drop during the nighttime. Well, what
if the sun wasn't there when the Earth turns around
and the sun's supposed to come up, what if the
sun just wasn't there anymore and you had one or
(45:18):
two or three or four days with no sun or
in the northern climates where you have very short days,
it's the same effect. If you go way north, say
up in Canada, or way south in Patagonia, very south.
What happens in the wintertime You might have a three
hour day, you might have three hours of sunlight, and
(45:39):
it's very low on horizon and it's just not enough
to heat things up, so that the temperature every day
keeps dropping and dropping and dropping until you get into
the depth of winter and it's really cold. I mean,
the Earth is literally frozen, you know. The atmosphere is frozen.
The atmosphphere is extremely dry because any vapor in the
(46:02):
air has fallen out. It is crystallized in the form
of snow, and that's very dry. But the point being
that we depend on a minute by minute influx of
energy from the sun to keep us warm. And as
soon as the sun goes down, as soon as it
gets low on the horizon even you start cooling down,
(46:23):
and as soon as the sun goes down, the temperature
starts dropping like pronto. So how can you contribute the
global climate change to one factor that is a greenhouse
effect that's going to have an effect in twenty years
when the sun and the energy being pumped into the
atmosphere right now from every coal burning plant, from every
(46:48):
automobile is going into the atmosphere right now, right now.
And what does the Earth do with all of that heat?
It expels it every night, every night, all of that
heat that comes from cold plants, from nuclear plants, gas
generated plants, from all of the industry that's burning energy, automobiles, trucks,
(47:12):
lighting everything, All of the energy produced from an electric
plant eventually ends up as some form of heat goes
up into the atmosphere. Eighty percent of what they're burning
at the power plant, nuclear, coal, whatever, is going up
into the atmosphere right now, and they don't count this,
(47:32):
I mean, just incredibly bad science. And so let me
get back to the idea of this BET's limit thing.
It does not apply to wind at all, because wind
is a compressible medium. The BET's limit only applies to
non compressible fluids. So that's not air, it's water, it's
(47:54):
hydraulic fluids, it's other forms of non compressible fluids. And
it's a kinetic energy transfer only like the flatboard on
the wing, it has nothing to do with aerodynamics because,
as I said, if you look at the drag on
(48:15):
the airplane that has the aerodynamic wing on it, it's
not a kinetic energy transfer. It's not the wind hitting
a wing and bouncing down and transferring kinetic energy that
causes the wing to lift up. It has very little
to do. In fact, there's very little loss compared to
a kinetic energy loss that would make the wing go up.
(48:39):
It's aerodynamic lift. It's the fact that error is a
compressible medium and the fact that it is not a
kinetic energy transfer that makes the airplane work. And so
it's the same situation. I realized this when I designed
the wing generator and patent, et cetera. That's why it
(49:01):
has a patent. But you can't get this into the
little teeny brains of the people that are out there
in this industry. Okay, so I think it's important, and
like I said, now at this point, you know more
than all of the engineers are general electric you know
more than all the engineers at Siemens and invest in
(49:25):
all of the engineers and physicists and et cetera that
work in the government that oversees all of the you know,
the specifications for wind energy systems, et cetera. You know
more than all of them combined. Because you listen to
this show. Okay, back again in real life, and I
(49:48):
hope that was informative. Just a few final things to
clean up this show. In twenty ten, I published a book.
It's called McKenny Wing Generator, World Energy Project, and in
there I have a special chapter on the myth of
alternative energy. So this I've been talking about for a
(50:12):
long time. In fact, I was on major national radio
shows around the early two thousands talking about this topic.
But I want to go through a few last things here,
a few last items. And also for those people in
engineering schools who are still teaching that bernoii's principle is
what causes lyft on wings. What they say is that
(50:36):
the larger distance that the airflows over the top of
the wing creates less pressure and there is more pressure
on the bottom of the wing, and so that's the
differential of pressure. If that were true, then lyft on
a wing would be linear, and lift on a wing
(50:58):
as the square of the velocity approximately. But and those
are very well verified experiments, So the Bernoilli's principle really
doesn't work for explaining lift on a wing. If you
put UH pressure sensors on a wing and do exactly
what I'm telling you, what you're gonna find out is
(51:19):
that the faster the wing goes in the airflow, the
uh it creates a vacuum on top of the wing,
and that's what lifts the airplane. That's the cause of lift,
and that's because air is a compressible fluid. Okay, So
just a few last things about three blade wind turbines.
(51:40):
Uh they have the skinniest part out at the very tip,
and that's where you want the most dark And of
course they're so big and clumsy that they could not
put anything significant out at the tip. But also the
wind just slides off the tip. The old dynamic lift
on the blade. Take a look at the blade. The
(52:02):
faster it goes, the more the blade is in line
with the plane of rotation, and so actually the lift
is not even in the direction of rotation on a
three blade wind turbine, it is perpendicular to the direction
of rotation of the blade, So the aerodynamic lift doesn't
do anything except fight against the tower, which causes a
(52:24):
lot of vibration and a lot of damage. That's why
the tower has to be so huge in addition to
the torque on the transmission, but because that big blade
is out there whipping back and forth perpendicular to the
plane of rotation, it's just absolutely crazy. Another thing is
(52:46):
that a propeller is not a reversible process. Let me
give you an example of a reversible process. Riding a
bicycle up a hill and then coasting back down, and
then riding your bicycle back up the hill and going
back down the hill is a reverse Propellers are not
a reversible process. And let me just explain a propeller
(53:07):
on an airplane. What are you doing. You're taking dead air,
completely stopped air, in your because the propellers rotating very rapidly,
you're causing a force. You're taking that air and moving
it backwards, and so a lot of air has to
come in from around the region into that into that
(53:29):
air flow and causing the thrust. But it doesn't work
that way in reverse. I'm sorry engineers who think wind
blades three blade wind turbans are some kind of marvel
is junk. It doesn't work. A propeller is not a
reversible process in engineering or in physics. And so once again,
(53:50):
I mean, these things don't work at all, and that's
why these stupid companies are going broke, which they should be.
And thank goodness you have a president who wrecked as
this and the shutting all his crap down. He's got
good advisors. Let's see the leading blade as these blades,
(54:11):
the three blade turbans, As the blades spin around, they
cause turbulence for the following blade. And also in a
real world situation, those blades are out there so far
that the wind and the wind direction, the wind velocity
is totally different all along those blades. So very very
small portion of the blades are actually doing positive work.
(54:35):
They're actually fighting each other, and so once again, just
a bad design. These blades are weigh upwards of sixty
five tons each, absolutely insane, and the vibration modes I
already talked about the wing lift in the perpendicular too
(54:58):
and causing torque on the t and then one of
the final things is these are low rpm. The bigger
you make them, the slower they go, the slower angular velocity,
the slower the rotation rate. And so what happens is
you need this transmission to gear them up physically to
the line frequency, and it just doesn't work. So there
(55:23):
are different ways to accomplish that, because you just can't
make big things rotate that fast, and so they're just
horrifically inefficient. Like I said before, if you increase the
lineal distance of the blades, you only get say you
double the distance the lineal distance, you only get double
the energy. And with the wing generator, which is excuse me,
(55:48):
my invention, you're getting a cubed So if you double
the size of the dimension, the lineal dimension, you get
eight times the amount of energy. If you triple the
lineal dimension, you get twenty seven times the amount of energy.
It goes as the cube of the lineal dimension. Okay,
(56:12):
so now just to talk a little bit about the
wing generator and talk about something positive. So I want
to talk about a properly designed wind system, and that
is one in which the aerodynamic lift is being used
in the rotary direction. So you can see it with
the wing generator, and you don't want to slow the
(56:35):
wind down. This is not a kinetic energy transfer. In
fact that I have a cute little story. I was
at a prize ceremony and there was a physicist there
from University California, and he came up to me and
he said, your wing generator is not big enough to
generate the energy you're claiming, and I said, well it does,
(56:57):
and so anyway. He then he said, but it's it
doesn't follow the BET's limit. And I simply said, it's
not a kinetic energy transfer. And he brings out his
laptop and he goes through the calculations and he shows
me he had already worked it all out for the
wing generator that I had been using and demonstrating. He said, see,
(57:19):
it doesn't work, and I simply repeated it. I said,
it's not a kinetic energy transfer. And when you see
these people react, it's like their world just dropped out
from under them. And he was like he realized the
second time I said it, it hit home and he
(57:39):
realized what I was saying. And he turned to me
and he said, you mean the wind energy industry has
been using the wrong measuring tool, the BET's limit all
of these years, and he slammed his computer shutting, and
he got up and he walked in and he was
just extremely angry. This is the kind of reaction you get.
But he realized it. He was a good physicist, realized
(58:03):
that he had been fooled. So at any rate, the
wing generator what happens is it's using aerodynamic lift in
the rotary direction, and so it's not subject to the
bets limit, which for all the reasons, this is why
(58:25):
I gave this lecture tonight, is to show you that
the three blade wind turbines, then the BET's limit that
they've been using is totally incorrect. And how you design
a properly designed wind energy system that uses wind in
airn which is a compressible fluid medium Newtonian fluid, and
(58:47):
how you use that and create aerodynamic lift. The other
thing about the wing generator is it has the drum
surrounding it. You see all of these other designs that
don't use did not understand. But what that does is
as the wind tries to slide out, these are rotating
very fast, and as the wind tries to slide out,
(59:08):
its traps, so that creates. It's a tremendous amount more
pressure on the underside of the wing, giving you about
a forty percent increase in energy and in efficiency using
the wing. And then the wind blows out the backside,
so one wing does not interfere with the airflow of
the next one. All of these things, like I said,
(59:31):
the wing generator cured about twenty four gross problems of
the three blade wind turbines, and that's why it is.
The additional thing with the wing generator is you can
make them very big, very large, up to one thousand feet,
the size that would replace nuclear or coal power plants.
(59:51):

Speaker 2 (00:52):
Good evening, everybody, and welcome again. Tonight, I'm going to
finally talk about the BET's limit of it and promising
this for quite a few weeks, and all of these
other incidental items came up, so my show got sidetracked.
Well those who are important issues, and so tonight I'm
going to talk about the BET's limit. So you might
(01:14):
be wondering what in the world is the BET's limit. Well,
it's something that affects all of you every day. It's
used in the used incorrectly, i should say, in the
wind energy industry. And so I'm going to go through
the physics of this and so this is going to
be a little bit technical, but I think that's what
(01:34):
people are looking for, not just glossing over a topic,
but going into depth and talking about it in detail.
And just to remind you that, tell your friends about
this show, tell your family, tell your friends, because we're
growing in numbers. This show only started last July and
is doing very well. So the reason people listen to me,
(02:00):
and this goes back fifty years as I have a
lot of experience. My background extends into places where most
people have never been, and I've been at tier levels
of science. I've explained before in the show that there
are various tiers of science. Tier one science is what
I call military science. It's the science that you never
(02:22):
see or hear about. It's not published in peer review journals,
and it's what is kept at the very highest levels
in government and in the secret agencies. I call it
military science. I've also worked around tier two people, which
would be like universities, where university professors published in peer
(02:45):
review journals, they get federal grants, etc. I don't take
federal money. I've never taken federal money to do my research.
I've always funded it myself. And so by the way,
I'm a degree physicist. I've an advanced degree, master's degree
in nuclear and solid state physics, and saw a very
(03:07):
good education and not getting a PhD is probably one
of the best things I ever did because it allowed
me to work in so many different fields. I worked
in the telecommunications industry for twenty five years in high
security locations. I have peer reviewed, public published papers in astrophysics,
(03:30):
space science, mathematics journals, and I've made a lot of
major discoveries in these fields. When I talk about something,
it's because it's because I've been there myself. It's not
because I read it on somebody's web page or read
it in a book someplace. When I tell you something,
(03:50):
it's because I've been there. I've done it myself, bought
the T shirt, as they say. I've been at many,
many international sciences conferences on other more esoteric topics. I've
been an invited speaker at places like Los Alamos National Laboratory,
talking about and really instructing the people there, high level astrophysicists,
(04:15):
plasma physicists on the true nature of the Solar system.
This is some of my work. The plasma discharge comet model,
the electrical nature of the solar system, the fusion based
stars and what makes them tick, etc. And I've also
been guests on all of the top radio shows, all
(04:36):
of the top platforms, and my background goes back fifty years.
So when I talk to you, I have a world
of experience and it's not something you're gonna find anyplace else.
So this is unlike any other podcast you're gonna see.
This is going to be true educational courses and unless,
as tonight's show will bear out, very high level discoveries
(05:03):
and criticism a lot of times of the science and
engineering industries. So anyway, tonight I'm going to be talking
about the BET's limit. Now what's the BET's limit and
what does it have to do with you? Well, the
wind energy industry is one of the most failed industries
(05:24):
on the planet. It gets huge, absolutely mammoth government incentives
and benefits, yet it is failing. How could it in
a world where energy is king the number one product
in the world is energy, How could a product in
the energy industry fail? It's the reason is because they
(05:47):
don't work. And so what Twenty five years ago I
sat down and after doing a study for a Midwest
company that was involved in biophy. I made a major
study of the electrical generation industry and found that it
was horrifically inefficient. And at the end of my study
(06:11):
for this company, they asked me to do a review
on three blade wind turbines and solar panels, which were
just beginning to crescendo at that time, the early two thousands,
and so the study I went through and I analyzed
these and I said, this stuff doesn't work. It'll never work,
(06:32):
it will never In My criteria was will it solve
the world energy problem or even make a dent in it?
And the answer was no. So I went about writing
a functional specification and I came up with what is
now a patented energy device, multiple patents on what I
call the wing generator. And tonight I'm going to talk
(06:52):
about the ability to extract energy from the wind and
how the wind industry. This is the core concept here
because it was on my November fifth and twelfth shows
last year on this television show and then also my
(07:13):
radio show. I have a radio show that's been going
on for twenty five years WWCR Nashville, Tennessee. But on
the November fifth and twenty and twelfth show, I talked
about the wing generator, so I'm not going to repeat that.
But what I'm going to do is discuss this concept
called the BET's limit. So theoretically, if you're in the industry,
(07:38):
what do you want to know? You want to know
how much energy can we extract out of this fluid
we call the wind. It's called a Newtonian fluid. That's
the technical term. So water, moving water or moving air
would be a technical term for all categorized under what
we call Newtonian fluids. Because they interact, they have mass,
(08:02):
and they can cause things to move. Therefore, you can
extract energy and cause turn that into various types of energy,
and specifically electrical energy and so or you could use
it to compress air or do other things. But to
begin with, what I'm going to do is to find
the BET's limit and give you an idea of how
(08:26):
this is being used incorrectly in the wind energy industry.
The basic components of the BET's limit is, Okay, you
have a column of air moving, and strictly the BET's
limit does not deal with air. So anyway, the first
rule of the BET's limit is that it deals only
(08:49):
with non compressible fluids. This is a big one. What
is a noncompressible fluid, well, water, hydraulic fluid, oil, mostly
liquids you would consider as non compressible. In other words,
you could build a hydraulic system out of them. And
as you put a hydraulic ram on something, the fluid
(09:11):
in those tubes and chambers is not going to compress
at least not very much. Air, on the other hand,
is a compressible fluid. That's why we use it in tires.
For example. You would not fill your tire with water.
That would not work very well. You fill it with air.
(09:33):
And why do you fill it with air is because
when you hit a bump, the tire compresses, the air compresses,
it acts like a shock absorber. And so that's the
entire principle of you would not use air in like
I say, in a hydraulic system. You simply would not
do that because it is a compressible fluid. And that
(09:56):
has everything to do with something called aerodynamic lift, which
I'll be talking about. Also. It comes into play because
when you start extracting energy from the wind, the same
thing happens when you fly an airplane. The wings are there,
and what's going on there what causes the wings to
create lift, and it's due to the fact that air
(10:17):
is a compressible Newtonian fluid. Okay, so number one, the
BET's limit only deals with non compressible fluids. Water. And
one of the best examples of the use of the
BET's limit is in a hydro dam. You have a
big body of water, you put a dam there, and
(10:40):
then you let the water spill over into these spillways,
and then it goes down into a tube literally a tube,
and it comes down into an impeller. We'll be talking
about the design of these impellers and the kinetic energy. Now,
this is the second part of the BET's limit. It's
at energy transfer. In other words, movement. Kinetic energy is
(11:04):
the energy of movement, and so if you're going to
extract energy from a kinetic energy system, what you're doing
is you got to slow that down. You have to
slow down that fluid. In this case, in a hydro dam,
you have water rushing down a tube and it as
(11:25):
you take energy out of it, there's a turbine at
the bottom that's spinning, and as you take energy out
of that fluid, it's going to slow down. So what happens.
The flange on this turbine head has to bend outwards.
In other words, that as the water slows down, the
(11:45):
tube that it's moving in has to get bigger to
accommodate the slower flow. If you don't do that, then
it's going to create a back pressure and slow down
the water coming down because it's a non compressible fluid. Okay.
So the BET's limit refers to the kinetic energy. How
(12:05):
much energy can you extract from a non compressible bluid? Okay,
And so there's an actual number it comes out. It's
a ratio. It's fifty nine point twenty four or something
like that percent of the energy the kinetic energy in
the tube you can extract. And this is kind of well,
(12:26):
a few things are going on here as you slow
down this column of moving kinetic material water in this case,
as you slow it down, Okay, you can slow it
down so much, but if you slow it down completely,
then the system backs up and it doesn't work anymore.
If you don't slow it down enough, then the water
(12:47):
just goes rushing through and you're not optimizing the energy extraction.
The kinetic energy extraction from that column of water. So
there's a balance there, and that balance turns out to
be theoretically nine point two four percent of the kinetic
energy in this column of water is obtainable as energy.
(13:09):
And then you connect that up to an electric turbine
and then it drives it creates electricity, three phase electricity.
You put it into a step up transformer, and then
you put that out over the high voltage lines which
transfers across the country, and then it is stepped down
through other transformers a series of transformers into local power,
(13:32):
which ultimately arrives at your business or house to use
as useful electricity. So that's the electrical grid system, but
powered by hydro dam and so anyway, the best's limit
is number one for a non compressible fluid, which is water.
(13:53):
Number two. It's a kinetic energy transfer. So you're taking
energy connecticut energy, the energy of motion, converting it into
energy of rotation rotational energy, which then drives a turbine,
which creates electricity which sends out and then you turn
on your light bulber, make your toast. Okay, So that's
(14:15):
the beginning. Now a number of a number of years
ago I gave a lecture on this and some of
those things. It just blows out so naturally and so concise.
So I'm going to actually delve into that lecture and
play it here, and then I'm going to come back
(14:36):
and talk about wind energy. But let me just preface this,
so I'll be repeating myself a little bit, but I
want to preface this by talking about the wind energy industry.
Whenever you talk to somebody in the wind energy industry
and you talk about efficiency, number of problems occur When
they quote in the newspaper that, oh, they're putting in
(14:57):
fifty or one hundred or so many three blade wind
turbines and it'll be enough energy to power seventy thousand homes.
What they're doing there is a lie, because what they're
doing is they're saying if these three blade wind turbines
were able to run at full capacity all the time,
(15:17):
they could power seventy thousand homes. But that's not what's
going to happen, because the wind doesn't blow all the time,
does it, And when it does blow, you only get
a bit about maybe maximum twenty percent of the energy
from those three blade wind turbines if they're not broken.
And so which most of them are today. But anyway,
(15:38):
that's another story. So anyway, the problem is that they
overquote what these things, and then the city councilor the
county council, or the state government or whoever says, oh,
look at all the energy these are going to produce
based on a lie. Okay, but let's get back to
the crux of the issue here with the BET's limit
(16:01):
is based on the movement of air, and air is
a compressible fluid. So right off the bat, wind energy
doesn't qualify for the BET's limit. Secondly, if you're going
to try to qualify for the BET's limit, you better
have something that traps the energy in that entire column
(16:22):
of air. Those three skinny little sticks that they call
turbine blades sticking up in the air, about ninety five
percent of the wind blows right through them. They don't work.
They don't trap the air. They don't trap the energy
in the wind. And if I have time at the
end of the show, I'm going to go through a
whole laundry list of problems with that system with a
(16:44):
three blade wind energy system. And third of all, when
you're extracting energy from a kinetic energy system like in
a hydro dam turbine, you can use a little bit
of hydro hydrodynamic lift, but primarily it's simply brute force.
(17:04):
You're putting the water down through a turbine blade. It
has a cut to it and anyway you can see
the pictures that I'm showing, it's going to take that
kinetic energy in the forward motion. The momentum of that
column of water is going to turn the turbine blade,
(17:27):
which is going to turn the electricity, and you're extracting
kinetic energies. Whereas in the three blade wind turbine, the
aerodynamic lift. They do have the shape of a propeller,
but the problem is they're perpendicular to the rotational direction,
so they actually work against the tower that they're on,
(17:48):
and they provide very little lift. It's like having a
flat board out there. So at any rate, I'm going
to play this previous discussion on the BET's limit, a
number of years ago lecture that I gave, and then
I'll come back and discuss this. The next topic I
(18:11):
want to talk about is called the bets law. Now,
this is going to be my science topic for the night,
The main science topic. Okay, let us imagine Now where
this is going is there's an industry standard that's been
used for literally one hundred years in the wind energy industry.
(18:33):
It is that old people trying to make devices that
work in the wind, and I finally invented the thing
that really works based on aerodynamic principles, et cetera. And
part of the problem has been people have been marching
down the wrong road because of misconceptions. Okay, so anyway,
(18:54):
this is going to be a little bit of an
insight into what we call kinetic kinetic energy transfer kinetic
energy transfer, and I'm going to talk about airplanes and
I'm going to talk about wind energy systems, and so
the whole idea here is to look at what a
(19:14):
kinetic energy transfer is and basically the Bets law, if
you look it up on the Internet or look it
up in an engineering manual or whatever, it was discovered,
and what it amounts to is the question is if
you're trying to extract energy from a column of air
or column of water, is in the case of a
(19:36):
hydro dam, how much energy can you actually extract from
the system? Is there a maximum amount? And so there's
a believe and I've talked to engineers before and the
first thing they do is they go, well, here's the
kinetic energy in the system. And so the belief is
that the only energy in the system is kinetic energy.
(20:00):
That's wrong. This is badly wrong. And let me just
put it this way. If that were true, airplanes couldn't fly.
And I'm going to explain that to you right now.
Imagine you have a model airplane in a wind tunnel.
We're gonna do all of this in a wind tunnel
because it's a little easier to understand. You have a
tunnel of air, there's a big fan at the end
(20:23):
of the tunnel which is creating the wind, and then
you put your airplane or your wind generator or whatever
in this wind tunnel. So that's the easiest way to
explain this. So we have a kind of a standardized
test facility to and this is going to be what
we call a Gadonkan experiment, a thought experiment. It's something
(20:45):
you have to conceive of in your mind. Okay, So
now take an airplane, put it in the wind tunnel.
You mounted on a sturdy post, and there's the airplane
all by itself, and you're gonna be able to measure
the on the airplane based on the wind coming into
the airplane on the nose side of the airplane and
(21:08):
hitting the wings. And then you have the drag on
a fuselage and on the engines, et cetera. And what
is the lift? How much lift are you going to
get out of this airplane? And the first thing we're
going to do on the airplane is we're going to
put flat boards. Just flat boards, Okay, And now imagine
(21:28):
here's another thing. If you're a skier, say a water
skier and or even a snow skier, you have two
boards on your feet. There's nothing aerodynamic about them. They're
just boards. They have a little flip up at the
front end, but they're just boards. And so like, if
you get behind a powerboat and you're on your water
skis and the boat gets up to speed, what are
(21:51):
you doing. You're pushing the boards against the medium, which
is the water, and if you go fast enough, the
boards cover enough waters area where it provides enough lift
to keep you up. If the boat goes too slow,
you start sinking down into the water and you start
(22:11):
having a tremendous amount of drag, but you can still
kind of keep up but anyway, these are flatboards. So
now imagine on your airplane in the wind tunnel, you
have flatboards on the wings. Okay, Now you turn on
the fan on the wind tunnel, and the question is
(22:33):
how much energy is lost, how much drag is there,
and therefore, how much engine power do you have to
supply to make that airplane go forward and fly. It's
because the airplane weighs so much, So it's a simple
vector equation. The weight of the plane is down, the
(22:53):
lift of the wings is up. The pressure of the
wind coming in the front side that causes drag. So
that causes a vector of drag. And now you have
to put the engines on there, and they're going to
push this thing forward. If you took it out in
a real world situation, and then if you put enough
(23:15):
power behind the engines in the engines, therefore this thing
would be able to fly. Okay, So it's a very
There's four vectors. There's the lift of the wings, there's
the weight of the airplane going down, there's the drag
of the airplane, and then there's the force of the engines.
There's four vectors here. Okay, So now we're going to
turn the fan on in the wind tunnel, and all
(23:37):
we have on the wings are flat boards, and this
is the whole point of a kinetic energy transfer. Now
you're going to tip the plane up or the wings up,
so that the wind comes in. It's the underside of
the flatboard wing. The wind is deflected down, and therefore
that causes an upward force on the flat board. That
(24:00):
is a pure kinetic energy transfer. Because the wind coming
in hits the wing, bounces down, which makes the wing
go up. And now if you had an airplane like this,
the airline industry would be in rough shape because what
(24:20):
you have out there is a wing, and it's called
a wing like a bird's wing, and it has an
aerodynamic shape. So now we're going to replace our boards,
which is a true kinetic energy transfer. There's no lift,
there's no aerodynamic lift on the flatboard. It's just a board.
And so when the wind comes in, it hits the wing,
(24:41):
the wind goes down. It's deflected down by the flat wing,
and that creates lift, and that's a kinetic energy transfer.
And there's a limit to how much you're going to
get out of that, because there's another issue. There's a
lot of drag that's being caused by that wind wing.
As the wind hits it, some is being deflected down
(25:05):
But remember that wind is coming into the front side,
the nose side of the airplane, and so it's also
pushing the wing backwards. There's two vectors that come off
the wind hitting that flat board. One is pushing it
backwards and one is where the wind is being deflected downwards,
(25:25):
and that makes the wing go up. This is the
flatboard wing. Now let's replace the flatboard wing with an
aerodynamic wing that has an airfoil. What is the difference?
And it turns out I'll give you the answer before
we start here. It's about a tenfold increase in force
(25:47):
in lift force, okay, and this is how it happens.
Let me use another example here. Now, let's take an
automobile and let's take a semitrailer trucking down the highway.
The truck is going down the highway and the back
of that truck is flat. So what happens the faster
(26:08):
the truck goes, the air comes around the side of
the truck and then it tries to get back and
flow around the backside of the truck. But what happens
because air is a compressible medium, it's not a perfect fluid.
It comes around and it leaves a vacuum in the
back of the truck. So some semi trucks that go
(26:31):
across country you will see kind of a flange that
comes around the back of the truck. And what that
does is it allows the airflow to come around the truck,
and it doesn't it reduces that vacuum at the back
of the truck. So literally the faster the truck goes,
the more vacuum that's being created or the car, and
(26:52):
that's literally sucking the truck backwards. There's a vacuum behind
the truck. And the same thing happens for a car.
So people talk, for example, about putting a new carburetor
onto a car that you know you get two hundred
miles out of the carburetor. Well, it's not going to
happen because the car design itself will not allow that
(27:13):
level of efficiency because what's happening is in a say
an SUV that has that square back. The fact, if
you're going seventy seventy five miles down the highway, miles
seventy miles per hour down the highway, then the wind
is creating a vacuum back there in that flat back
of the vehicle and sucking it backwards. Okay, now here's
(27:39):
what happens with a wing, an aerodynamic wing. We put
the airplane back in the wind tunnel. We put on
the fan, the same amount of fan wind speed that's
coming into the air craft into the aircraft, and so
it's the exact same scenario as before, the same wind speed,
et cetera. Except the only difference is now you have
(28:00):
airfoil wings on the airplane, not flat boards. What is
the difference. You're still going to have that wing a
little bit of an angle, but not as much as
the flat board. And what happens is some of the
wind is going to hit the underside of the wing.
It's going to cause pressure on the underside of the wing.
But the thing that's really causing the lift is the
(28:22):
wind that comes over the front side of the wing.
And if you look at a well designed wing, it's round,
it's a perfect circle on the front edge. So the
wind comes in, the wind splits. Some of it goes
up above and some of it goes down below. And
so the part that goes below there's a little bit
of an angle to the wing, and so the wind
(28:44):
is hitting the bottom of the wing and causing more
pressure than if you had a dead air situation. But
what really happens is some of that air goes over
the top side of the wing, and just like in
the back side of the semi trailer, it can't get
down to the wing. The faster and faster you go
(29:05):
relative to the wind, the wind cannot get back down
on the top of the wing that fast, and so
it creates a vacuum. There's another way of looking at this.
Most people look at it in terms of what is
known as the Bernouilli principle. But what's really happening here
is you're creating a vacuum on the upper side of
the wing. In that vacuum is literally what lifts the
(29:28):
vehicle up. The airplane and you'll see some airplanes now
have a little flip up at the end of the wing.
And that is something that the Right brothers discovered when
they very first had an airplane. They went out in
the field and they calculated how much lift they should
get off of a wing, and they had kind of
a square shaped wing, and they went out and they
(29:52):
really couldn't get enough lift off of this, and they
couldn't figure out why. So they went back and they
actually created the very first wind tunnel and they put
their model of their airplane into the wind tunnel, and
then they tried different configurations of wings, and they did
something very interesting. They did a smoke trailing, and what
they discovered is that the underside of the wing had
(30:15):
higher pressure, the upper side of the wing had less pressure,
but the wind was coming around the edge of the wing,
the tip of the wing, over the top of the
wing and ruining the vacuum on the top of the wing.
So they figured out that the longer wing worked better.
Even though you had exactly the same surface area. You
(30:37):
had exactly the same amount of area of your wing,
the long wing worked better, and they didn't really realize.
Now there's let's take a look at a vulture or
a condor, or an eagle, a soaring bird. Look at
any of them in flight, and you'll see at the
end of their wings they have a group of feathers
(31:00):
that sticks straight out from the end of their wings
and they're flipped up. So what happens as the air
from the underside of the wing comes up those feathers
redirect the wind up and away from the top side
of the wing, and that gives you a better vacuum.
These are the principles of aerodynamics, and so I could
(31:22):
go on and on about this topic. But the point
here is what I've been trying to instruct you with
is the difference between an airfoil and a kinetic energy
transfer something that is This is basic one oh one physics,
or at least aerodynamics one oh one physics. The bets
(31:45):
law is something that has been used in the wind
industry to give an upper limit of the amount of
energy that is in a column of wind. And let
me give you a perfect example of the u use
of the BET's law. Now, the BET's law has some assumptions.
When you go into the calculations and the theoretical construction
(32:08):
of the BET's law, what happens is, let's take a
hydro dam. You have a big lake and then you
have basically a funnel where the water pours over it's
near the dam. You have a dam, then it drops
down and down at the bottom of the dam. In
(32:28):
a housing, you have tubes where the water comes down
the tube. So you get a lot of pressure because
of the water pressure coming down this tube. It's a
constant diameter tube and it comes into a basically a
propeller blade type of system, but it's different than a
regular propeller blade. It looks like a series of flanges.
(32:52):
And what happens is as the water enters this propeller
which is connected to the electric generator by the way,
as the water comes down into this generator, the water
enters and as you extract kinetic energy out of the
water column, the water slows down because you have extracted
(33:14):
kinetic energy that's going into spinning the blade. Now, what
happens as the water slows down if you didn't make
the flange expand and get bigger, in other words, the
propeller blades go outwards and give in there it moves
in a bigger diameter tube because the water's now moving slower.
(33:37):
If you did not do that, the slower water would
back up and create a back pressure up the tube,
and it would limit the amount of energy you could
get out of the water. So this is the design
of a perfectly constructed example of the BET's limit. Because
water is a non compressible fluid, you can use water
(33:59):
for example, in a hydraulic ram. You could use it
in place of hydraulic fluids. What is a hydraulic fluid?
It's a non compressible medium. Now, let me ask you
a question, all you engineers and even third graders out there,
would you use air in a hydraulic system? And a
(34:22):
hydraulic system is where you have a hydraulic ram. There's
a piston inside of a big long tube, and then
you have a little motor there or sometimes a pretty
big motor that's driving pressure into that hydraulic fluid into
the columninet makes the arm go out, and you use
(34:42):
these on big road equipment, etc. And so anyway, the
hydraulic fluid in that hydraulic system is a non compressible medium.
The question is would you use air in that system
in place of hydraulic fluid? And the answer is no.
And the reason is because error is a compressible medium.
(35:07):
If you tried to pump air into that system, it
wouldn't work very well at all because air is a
compressible medium. So the very first thing about the BET's
limit is that air is a compressible medium. It doesn't apply.
It does not apply to aerodynamic systems. The BET's limit
(35:30):
refers to systems that are kinetic energy and they have
the fluid that's used the Newtonia. They're called Newtonian fluid.
So any fluid is a Newtonian fluid, but it would
have to be like water or hydraulic fluid or oil
or something that is non compressible to work with the
(35:54):
BET's limit. So they've been completely using this incorrectly. And
I had a little run in with a let's say,
somebody high up in the wind energy world this past
week and immediately started spouting off about the betslimit. And
that's why I'm talking about this because everybody a general
(36:18):
Electric or Semens or Vesta, or in the government, or
people dealing with government contracts dealing with energy, have this
belief in their brain that the maximum amount of energy
you can get out of a wind system is limited
by the betslimit. And there's also another issue that if
(36:39):
you have a system where you're extracting kinetic energy out
of a column fluid moving column of fluid, then necessarily
that column has to slow down because you're extracting energy
from it. It's kinetic energy. Kinetic energy is energy of motion,
(37:00):
and the equation for that is one half MV squared.
So the faster it's going, the bigger velocity the square
of the velocity times the mass. I mean, that just
gives you the kinetic energy. And if you take some
energy out of there, you're going to reduce the mass
is the same, so you're going to reduce the velocity.
(37:23):
And therefore that's how you extract energy out of the system.
But you can't take all of the energy out because
the water would stop and it would back up your
system and it wouldn't work anymore. So the BET's limits
comes up with a number that's fifty nine percent. I
believe it's around fifty nine percent. Anyway, that's the maximumount
(37:43):
of energy you can extract out of a kinetic energy system.
But wind it does not apply because, as I talked
about in the airplane example, a pure kinetic energy airplane
would be a flat board. An aerodynamic airplane wing would
(38:03):
be an aerodynamic shape. And the reason you're getting lift
out of this, you're not extracting energy out of the
wind to create the lift. What's happening is the faster
you go with your wing relative to the air, the
more vacuum you're creating on the top side of the wing,
and the only drag is that little bit of drag
(38:23):
on the front of the wing. So it's not the
drag on the front of the wing is not what's
causing the lift. It's kind of a it's a cost,
but it's not the energy that's used to lift the wing.
It's the fact that there's you're creating a vacuum on
the upper side of the wing, and that's pulling the
(38:44):
wing up. And that's why a very small wing, a
relatively small wing, can lift one hundred thousand pounds jet airliner.
And that's why you have to start going down a
runway when you take off. You take off, airplane starts
taxing down a runway and all of a sudden, the
vacuum on the upper side of those wings. You can
(39:05):
see the wings starting to lift up, and pretty soon
they lift up the entire airplane and away it goes
off into the blue horizon, as they call it. But
that's because it's not because of the BET's limit. An
airplane that had a physical kinetic energy transfer only you
(39:26):
would have to have engines ten times as big as
they are. They would use ten times as much fuel,
and they would fly one tenth the distance, you would
not have airplanes flying around the globe. Okay, So anyway,
the very important point here is that aerodynamic lift gives
you a big advantage when you're creating aerodynamic systems. So
(39:52):
when I created the wing generator, I knew this, and
it's so incredible to when you intererd to people, the
first thing out of all of their mouths is, well,
you have a thing called the BET's limit. These people
are ignorant morons. They've been It's so typical. It's so
(40:15):
typical where you have engineering schools, and it's let me
use another example. People that believe hurricanes are caused by
warm water, and it's universally believed in the meteorol meteorological world,
in the universities wherever you go, and you can do
(40:38):
a very simple calculation. As a hurricane passes over the ocean,
there's a slight drop in temperature of the surface of
the ocean and it's down to maybe a few inches
in the surface water of the ocean, not very deep.
But what's going on with the wind of the hurricane
(40:59):
is blowing over the surface of the water and it
evaporates the water. That's where all of the water comes
in the hurricane. It's being evaporated off the surface of
the ocean. And if you look at the amount of
water that's in the hurricane and you calculate the latent
heat of evaporation that's a chemical term. What you will
(41:20):
find is that the amount of energy loss due to
that slight temperature change as the hurricane passes over the
warm water is just equal to the amount of water
in the hurricane itself. So that's where it's coming from.
It doesn't power the hurricane. Good grief. Let me give
(41:41):
you another example, a very simple example. You see a
car going down the road, and it's the first time
you ever see a car going down the road, and
you ask a person what's making this cargo down the road?
And you see that exhaust pipe coming out of the
back of the car. So you think, well, this must
be a rocket powered car because there's exhaust coming out
(42:03):
of the back of the car, out of the exhaust tube,
and it's going one way and the car's going the
other way. So it must be that the exhaust coming
out the exhaust pipe at the tail end of the
car is making the car don't go down the road,
but you make a quick calculation and you realize that
the amount of vapor and the speed that's coming out,
and you look at the mass of the car and
(42:24):
you go, well, this could not possibly be what's causing
the car to go down the road. There must be
something else going on here. And then you would lift
up the hood and you go, well, gee, there's a
big internal combustion engine in here with a transmission and
a lot of loss due to all of the inefficiencies
in the engine, and it's burning some kind of high
(42:46):
combustible fuel called gasoline, and that's what's making the cargo
down the road. It's the same thing over and over
and over again. Let me give another example. How about
climate change, one of our favorite topics. And imagine that
(43:06):
somebody believes that the greenhouse effect is going to raise
the global temperature by point one degrees in the next
twenty years due to greenhouse gas emissions. Okay, well, okay,
let's talk about that. Let's look at an automobile again,
or how about a nuclear power plant or a coal
(43:29):
fired power plant for example, a little better example. So
let's look at the coal fired power plant. It is
burning a coal in about eighty percent of the heat
that's generated goes right up into the atmosphere right now.
And then there's some carbon dioxide that's given off from
the burning, and that carbon dioxide goes into the air.
(43:51):
And the theory is that over a ten to twenty
year period that carbon dioxide in the air is going
to cause an trap of heat into the atmosphere and
overall it's going to raise the Earth's atmospheric temperature by
zero point one percent. Well, it's about one kazillionth of
the amount of heat that's going directly into the atmosphere
(44:14):
right now. So once again, science has nothing to do
with the emotional contribution that people have towards climate change.
Or how about the Sun which provides us minute to
minute energy, and if remember at night. Let's talk about
(44:34):
this as the night time comes no matter where you
are in the world, except if you're in the above
the Arctic circle in the summertime, then you have twenty
four hours sun. But the rest of us, poor people
that live sub Arctic circle zones, you have daytime and
then you have nighttime. Well, what happens when nighttime comes,
(44:56):
The temperature drops. The temperature goes down, and it might
be a twenty degree drop during the nighttime. Well, what
if the sun wasn't there when the Earth turns around
and the sun's supposed to come up, what if the
sun just wasn't there anymore and you had one or
(45:18):
two or three or four days with no sun or
in the northern climates where you have very short days,
it's the same effect. If you go way north, say
up in Canada, or way south in Patagonia, very south.
What happens in the wintertime You might have a three
hour day, you might have three hours of sunlight, and
(45:39):
it's very low on horizon and it's just not enough
to heat things up, so that the temperature every day
keeps dropping and dropping and dropping until you get into
the depth of winter and it's really cold. I mean,
the Earth is literally frozen, you know. The atmosphere is frozen.
The atmosphphere is extremely dry because any vapor in the
(46:02):
air has fallen out. It is crystallized in the form
of snow, and that's very dry. But the point being
that we depend on a minute by minute influx of
energy from the sun to keep us warm. And as
soon as the sun goes down, as soon as it
gets low on the horizon even you start cooling down,
(46:23):
and as soon as the sun goes down, the temperature
starts dropping like pronto. So how can you contribute the
global climate change to one factor that is a greenhouse
effect that's going to have an effect in twenty years
when the sun and the energy being pumped into the
atmosphere right now from every coal burning plant, from every
(46:48):
automobile is going into the atmosphere right now, right now.
And what does the Earth do with all of that heat?
It expels it every night, every night, all of that
heat that comes from cold plants, from nuclear plants, gas
generated plants, from all of the industry that's burning energy, automobiles, trucks,
(47:12):
lighting everything, All of the energy produced from an electric
plant eventually ends up as some form of heat goes
up into the atmosphere. Eighty percent of what they're burning
at the power plant, nuclear, coal, whatever, is going up
into the atmosphere right now, and they don't count this,
(47:32):
I mean, just incredibly bad science. And so let me
get back to the idea of this BET's limit thing.
It does not apply to wind at all, because wind
is a compressible medium. The BET's limit only applies to
non compressible fluids. So that's not air, it's water, it's
(47:54):
hydraulic fluids, it's other forms of non compressible fluids. And
it's a kinetic energy transfer only like the flatboard on
the wing, it has nothing to do with aerodynamics because,
as I said, if you look at the drag on
(48:15):
the airplane that has the aerodynamic wing on it, it's
not a kinetic energy transfer. It's not the wind hitting
a wing and bouncing down and transferring kinetic energy that
causes the wing to lift up. It has very little
to do. In fact, there's very little loss compared to
a kinetic energy loss that would make the wing go up.
(48:39):
It's aerodynamic lift. It's the fact that error is a
compressible medium and the fact that it is not a
kinetic energy transfer that makes the airplane work. And so
it's the same situation. I realized this when I designed
the wing generator and patent, et cetera. That's why it
(49:01):
has a patent. But you can't get this into the
little teeny brains of the people that are out there
in this industry. Okay, so I think it's important, and
like I said, now at this point, you know more
than all of the engineers are general electric you know
more than all the engineers at Siemens and invest in
(49:25):
all of the engineers and physicists and et cetera that
work in the government that oversees all of the you know,
the specifications for wind energy systems, et cetera. You know
more than all of them combined. Because you listen to
this show. Okay, back again in real life, and I
(49:48):
hope that was informative. Just a few final things to
clean up this show. In twenty ten, I published a book.
It's called McKenny Wing Generator, World Energy Project, and in
there I have a special chapter on the myth of
alternative energy. So this I've been talking about for a
(50:12):
long time. In fact, I was on major national radio
shows around the early two thousands talking about this topic.
But I want to go through a few last things here,
a few last items. And also for those people in
engineering schools who are still teaching that bernoii's principle is
what causes lyft on wings. What they say is that
(50:36):
the larger distance that the airflows over the top of
the wing creates less pressure and there is more pressure
on the bottom of the wing, and so that's the
differential of pressure. If that were true, then lyft on
a wing would be linear, and lift on a wing
(50:58):
as the square of the velocity approximately. But and those
are very well verified experiments, So the Bernoilli's principle really
doesn't work for explaining lift on a wing. If you
put UH pressure sensors on a wing and do exactly
what I'm telling you, what you're gonna find out is
(51:19):
that the faster the wing goes in the airflow, the
uh it creates a vacuum on top of the wing,
and that's what lifts the airplane. That's the cause of lift,
and that's because air is a compressible fluid. Okay, So
just a few last things about three blade wind turbines.
(51:40):
Uh they have the skinniest part out at the very tip,
and that's where you want the most dark And of
course they're so big and clumsy that they could not
put anything significant out at the tip. But also the
wind just slides off the tip. The old dynamic lift
on the blade. Take a look at the blade. The
(52:02):
faster it goes, the more the blade is in line
with the plane of rotation, and so actually the lift
is not even in the direction of rotation on a
three blade wind turbine, it is perpendicular to the direction
of rotation of the blade, So the aerodynamic lift doesn't
do anything except fight against the tower, which causes a
(52:24):
lot of vibration and a lot of damage. That's why
the tower has to be so huge in addition to
the torque on the transmission, but because that big blade
is out there whipping back and forth perpendicular to the
plane of rotation, it's just absolutely crazy. Another thing is
(52:46):
that a propeller is not a reversible process. Let me
give you an example of a reversible process. Riding a
bicycle up a hill and then coasting back down, and
then riding your bicycle back up the hill and going
back down the hill is a reverse Propellers are not
a reversible process. And let me just explain a propeller
(53:07):
on an airplane. What are you doing. You're taking dead air,
completely stopped air, in your because the propellers rotating very rapidly,
you're causing a force. You're taking that air and moving
it backwards, and so a lot of air has to
come in from around the region into that into that
(53:29):
air flow and causing the thrust. But it doesn't work
that way in reverse. I'm sorry engineers who think wind
blades three blade wind turbans are some kind of marvel
is junk. It doesn't work. A propeller is not a
reversible process in engineering or in physics. And so once again,
(53:50):
I mean, these things don't work at all, and that's
why these stupid companies are going broke, which they should be.
And thank goodness you have a president who wrecked as
this and the shutting all his crap down. He's got
good advisors. Let's see the leading blade as these blades,
(54:11):
the three blade turbans, As the blades spin around, they
cause turbulence for the following blade. And also in a
real world situation, those blades are out there so far
that the wind and the wind direction, the wind velocity
is totally different all along those blades. So very very
small portion of the blades are actually doing positive work.
(54:35):
They're actually fighting each other, and so once again, just
a bad design. These blades are weigh upwards of sixty
five tons each, absolutely insane, and the vibration modes I
already talked about the wing lift in the perpendicular too
(54:58):
and causing torque on the t and then one of
the final things is these are low rpm. The bigger
you make them, the slower they go, the slower angular velocity,
the slower the rotation rate. And so what happens is
you need this transmission to gear them up physically to
the line frequency, and it just doesn't work. So there
(55:23):
are different ways to accomplish that, because you just can't
make big things rotate that fast, and so they're just
horrifically inefficient. Like I said before, if you increase the
lineal distance of the blades, you only get say you
double the distance the lineal distance, you only get double
the energy. And with the wing generator, which is excuse me,
(55:48):
my invention, you're getting a cubed So if you double
the size of the dimension, the lineal dimension, you get
eight times the amount of energy. If you triple the
lineal dimension, you get twenty seven times the amount of energy.
It goes as the cube of the lineal dimension. Okay,
(56:12):
so now just to talk a little bit about the
wing generator and talk about something positive. So I want
to talk about a properly designed wind system, and that
is one in which the aerodynamic lift is being used
in the rotary direction. So you can see it with
the wing generator, and you don't want to slow the
(56:35):
wind down. This is not a kinetic energy transfer. In
fact that I have a cute little story. I was
at a prize ceremony and there was a physicist there
from University California, and he came up to me and
he said, your wing generator is not big enough to
generate the energy you're claiming, and I said, well it does,
(56:57):
and so anyway. He then he said, but it's it
doesn't follow the BET's limit. And I simply said, it's
not a kinetic energy transfer. And he brings out his
laptop and he goes through the calculations and he shows
me he had already worked it all out for the
wing generator that I had been using and demonstrating. He said, see,
(57:19):
it doesn't work, and I simply repeated it. I said,
it's not a kinetic energy transfer. And when you see
these people react, it's like their world just dropped out
from under them. And he was like he realized the
second time I said it, it hit home and he
(57:39):
realized what I was saying. And he turned to me
and he said, you mean the wind energy industry has
been using the wrong measuring tool, the BET's limit all
of these years, and he slammed his computer shutting, and
he got up and he walked in and he was
just extremely angry. This is the kind of reaction you get.
But he realized it. He was a good physicist, realized
(58:03):
that he had been fooled. So at any rate, the
wing generator what happens is it's using aerodynamic lift in
the rotary direction, and so it's not subject to the
bets limit, which for all the reasons, this is why
(58:25):
I gave this lecture tonight, is to show you that
the three blade wind turbines, then the BET's limit that
they've been using is totally incorrect. And how you design
a properly designed wind energy system that uses wind in
airn which is a compressible fluid medium Newtonian fluid, and
(58:47):
how you use that and create aerodynamic lift. The other
thing about the wing generator is it has the drum
surrounding it. You see all of these other designs that
don't use did not understand. But what that does is
as the wind tries to slide out, these are rotating
very fast, and as the wind tries to slide out,
(59:08):
its traps, so that creates. It's a tremendous amount more
pressure on the underside of the wing, giving you about
a forty percent increase in energy and in efficiency using
the wing. And then the wind blows out the backside,
so one wing does not interfere with the airflow of
the next one. All of these things, like I said,
(59:31):
the wing generator cured about twenty four gross problems of
the three blade wind turbines, and that's why it is.
The additional thing with the wing generator is you can
make them very big, very large, up to one thousand feet,
the size that would replace nuclear or coal power plants.
