What's Your Problem?

Getting energy from nuclear fusion has been a dream for decades; it would be cheap, abundant, and safer than today’s nuclear fission reactors. Billions of dollars have flowed into fusion startups in recent years, but reliable, economic fusion power may still be decades away.

Greg Piefer is the founder of a fusion company called Shine, where he’s pursuing a different path. Rather than go straight to fusion as a so...

Recycling plants take in a huge amount of random (and occasionally hazardous) stuff, which they then have to turn into reliable outputs that their customers will buy. That’s why Rebecca Hu Thrams calls recycling “the most demented form of manufacturing on the planet.” Rebecca is the co-founder of Glacier, and her problem is this: Can you use AI and robots to make recycling a somewhat less demented business?

Jared Baeten is senior vice president in virology at Gilead Sciences. Jared's problem is this: In a world without a vaccine, how do you make a medicine that people will actually take to help prevent HIV?

There’s already a daily pill that reduces the risk of getting HIV, but a majority of people who are at high risk are unwilling or unable to take it.

So Jared and his colleagues are developing a new drug, lenacap...

We need better, cheaper ways to store solar and wind energy when it’s dark out and the wind isn’t blowing.

One option: Compressing air in underground caverns when energy is abundant, then blowing it back out to create energy when you need it. It’s an old idea, but it has some fundamental problems.

Curtis VanWalleghem, the co-founder and CEO of Hydrostor, thinks his company has solved those problems...

There are moments in history when people make huge technological advances all of a sudden. Think of the Manhattan Project, the Apollo missions, or, more recently, generative AI. But what do these moments have in common? Is there some set of conditions that lead to massive technological leaps?

Byrne Hobart is the author of a finance newsletter called The Diff, and the co-author of Boom: Bubbles and the End of Stagnation. In the book...

AI works well in the virtual world. That’s partly because the internet provides so much data to train AI models. But there’s no analogous data set for the physical world – and as a result, AI doesn’t work as well there… yet.
