Everybody in the Pool

This week on Everybody in the Pool, we’re talking about one of the biggest hurdles in the clean energy transition — how to make electric vehicles as fast and easy to refuel as gas cars.

Our guest is Will Fitzhugh, co-founder and CEO of Adden Energy, a Harvard spinout developing self-healing solid-state lithium metal batteries that could charge fully in under ten minutes. These next-generation batteries promise longer range, fast...

This week on Everybody in the Pool, we’re talking water — and the invisible pollutants hiding in it. Microfibers from textiles are one of the biggest sources of microplastics in our oceans, choking marine ecosystems and undermining the ocean’s role as the planet’s carbon sink.

Our guest is Adam Root, founder and CEO of Matter, who shares his insane founder story, from £250 and a shed to a budding Japanese street food empire to Matte...

This week on Everybody in the Pool, we’re geeking out on money. Because even the best climate solutions won’t scale without serious capital behind them.

Our guest is Dawn Lippert, founder of Elemental (a nonprofit investor) and founding partner of Earthshot Ventures (a venture fund). She’s basically building an all-terrain vehicle for climate finance — covering philanthropic, project, and venture capital — to bridge the “valley of d...

This week on Everybody in the Pool, we’re heading to Napa Valley... sadly not literally. This time, anyway! David Pearson, president of Joseph Phelps Vineyards, has spent his career in wine, but he’s now leading a transformation that’s as much about climate solutions as it is about Cabernet. It’s a story about farming, philosophy, and, yes, some really good wine.

We dig into:

• What regenerative farming really means — ...

Now for something fun — that can also be electricity generating infrastructure, if need be. My guest is Toby Kraus, co-founder and CEO of Lightship RV, the first American company to build all-electric RVs. The Lightship isn’t just a camper — it’s a battery on wheels, with solar on the roof, a pop-up design for aerodynamics, and its own motor to cancel out towing drag. That means you can take it off-grid for a week … or park it in y...

We’ve been talking storage, reliability, and the grid … but what if we could just make more clean energy in more places? This week on Everybody in the Pool, we look at solar in a whole new way.

My guest is Anthony Letmon, co-founder and CEO of Kardinia Energy, which makes ultra-lightweight, recyclable printed solar. Imagine solar that looks more like a concert poster than a heavy panel. You can roll it up, ship it anywhere, and stic...

We’re wrapping up the Smart Grid Series with a rocket scientist who thinks the next big thing in batteries might actually be … zinc.

My guest is Mike Burz, co-founder and CEO of Enzinc, which is commercializing a zinc “sponge” anode developed with the U.S. Navy. The breakthrough: solving the dendrite problem that has historically killed rechargeable zinc batteries. The result? A safe, recyclable, low-cost chemistry that could power ...

This special episode is brought to you by RE+—North America’s largest gathering of clean energy professionals, developed by the Smart Electric Power Alliance (SEPA) and the Solar Energy Industries Association (SEIA).

On Monday, Sept. 8, 2025, I gave the opening keynote at RE+ in Las Vegas about where the energy transition is headed—followed by a panel with two leaders building it at scale:

• Ray Henger, CEO of Copia Power (developi...

Continuing our Smart Grid Series, we zoom in on reliability — because building more solar and wind doesn’t matter if the grid itself can’t stay stable. We’ve seen what happens when it fails: blackouts in Spain and Portugal earlier this year, near misses in Texas, rolling outages in California.

My guest is David Hebert, VP of Global Sales & Business Strategy at Wärtsilä Energy Storage. Wärtsilä is a 190-year-old company that now ...

For the next few episodes, we’re digging into the wild world of energy and the aging global electricity grid. This week, we start where reliability begins: utility-scale storage. The grid we have was built for one-way power plants; the grid we need has to juggle rooftop solar at noon, heat waves at 6 p.m., EVs, and data centers galore.

My guest is Tom Sisto, founder & CEO of XL Batteries. His team is commercializing a pH-neutral...

This week on Everybody in the Pool, we’re celebrating our 100th episode with a look at what matters most: your actions.

Since this show began a little over two years ago, the goal has been simple — to spotlight innovation, ingenuity, and capital coming together to tackle the climate crisis. Hope is stronger than fear, but hope alone isn’t a plan. This milestone episode is about agency — the choices we make in our own lives, and how ...

This week on Everybody in the Pool, we’re diving into ocean intelligence. Despite covering more than 70% of the Earth, the ocean remains one of the least understood parts of our climate system — and that knowledge gap has huge consequences for weather prediction, global commerce, and climate resilience.

Our guest is Tim Janssen, co-founder and CEO of Sofar Ocean, a company building the world’s largest privately deployed network of o...

This week on Everybody in the Pool, we’re talking ocean tech — in a slightly roundabout way. Nano-bubbles are a tiny but powerful technology that’s helping to make a big climate impact across wastewater treatment, irrigation, aquaculture, and more.

Our guest is Nick Dyner, CEO of Moleaer, a company that manufactures systems to produce nano-bubbles — microscopic bubbles that can enhance chemical, physical, and biological processes. T...

This week on Everybody in the Pool, we’re kicking off a mini-series on the ocean — the world’s largest carbon sink, a source of food for nearly half the global population, home to 80% of animal life on Earth, and heating faster than expected. It’s also a climate tech category full of untapped investment opportunities.

Our guest is Kate Danaher, Managing Director at S2G Investments, where she co-leads the firm’s oceans and seafood st...

This week on Everybody in the Pool, we’re continuing Storyteller Summer with a stand-up comic who proves you can turn any job into a climate job — even one that usually involves jokes about socks.

Our guest is Stuart Goldsmith, a veteran stand-up comedian and host of The Comedian’s Comedian podcast, who now focuses almost entirely on the climate crisis. But instead of lectures or charts, Stuart brings humor, humility, and a heal...

This week on Everybody in the Pool, we’re diving into the power of convening — and what happens when global climate leaders, local food producers, indigenous communities, philanthropists, and data nerds get in the same room... and then go mountain biking together.

Our guest is Aimée Christensen, a longtime climate champion and founder of Christensen Global, the Sun Valley Forum, and the Sun Valley Institute for Resilience. From nego...

This week on Everybody in the Pool, we explore the pioneering world of rare earth metal recycling with Ahmad Ghahreman, CEO and co-founder of Cyclic Materials. This is a a technology with big environmental implications, and a whole lot of geopolitical ones also. Rare earth metals are used to make magnets that are part of electric motors and wind turbines, on the clean tech side, but also kind of everything else electronic, inc...

This week on Everybody in the Pool, we’re sticking with the theme of climate storytelling and climate communication with a well-known activist and advocate for justice, climate action, equity, and getting out the vote. Rev Yearwood is the president of the nonprofit Hip Hop Caucus, which works to engage young people around voting and community service, and he also advises the Bloomberg Foundation on climate storytelling projects. He...

This week on "Everybody in the Pool," we are on one last week of summer vacation but we didn’t want to leave you without anything to listen to any longer! One of Molly’s other projects is a podcast called Futureverse, where she and co-host Ramanan Raghavendran interview authors of climate fiction, to try to understand how fiction and science fiction imagine a present or a future in the world of a changing climate. Recently, they in...
