Everybody in the Pool

This week on Everybody in the Pool, we're diving into the world of protein production — in reverse. Recently, the USDA released a new food pyramid that controversially places red meat and dairy at the top. That, combined with the global and particularly American obsession with protein, make it a great time to talk to Ross Milne, CEO of Leaft Foods. Leaft is developing a groundbreaking technology t...

Here’s a bonus episode for you to kick off 2026. Back in episode 97, we interviewed Kate Danaher of S2G Investments about investing in the ocean economy. S2G are actually investors in a few of the companies we’ve had on Everybody in the Pool, including Matter, Moleaer, and Sofar Ocean. So this week, we’re featuring one of their interviews as they prepare to launch their new season. The S2G Podcast...

This week on Everybody in the Pool , we’re starting the year with an audacious question: what if we reinvented one of the most basic materials in the world? Decarbonizing the built environment means tackling the stuff we use everywhere — wood, concrete, and steel — at the same time we’re trying to build millions of new homes, strengthen supply chains, and reduce our exposure to geopolitical and cl...

This week on Everybody in the Pool , we’re diving into one of the biggest bottlenecks in the clean energy transition: critical minerals —the lithium, nickel, cobalt, copper, and precious metals we need for EVs, batteries, and the grid. The problem isn’t that we’re running out. It’s that extraction and refining are expensive, polluting, and increasingly constrained by geopolitics. My guest is Adam...

This week on Everybody in the Pool , we’re talking about one of the biggest blockers to real climate action: amazing solutions that never scale because no one pays for them . My guest is Grant Canary , founder and CEO of Mast Reforestation , a company rebuilding forests after catastrophic wildfires — and reinventing carbon credits so that reforestation can actually fund itself. Mast takes the most...

This week on Everybody in the Pool , we’re starting in full aspirational mode (with one of my least climate-friendly obsessions) — with iconic classic cars rebuilt as state-of-the-art EVs . Think: vintage Porsches, Land Rovers, Pagodas, even a GT40… all stripped to bare metal, fully restored, and reborn as clean-air electric machines. Yeah, I’m dying over here. My guest is Justin Lunny , founder a...

This week on Everybody in the Pool , we’re talking about one of the least-visible but largest waste problems in the world: food processing waste . Every time fruits or vegetables are peeled, chopped, juiced, or processed, mountains of perfectly good plant material get thrown out or sold for pennies. It’s expensive, it’s inefficient, and it’s a huge climate problem. My guest is Michelle Ruiz , foun...

This week on Everybody in the Pool , more power, right beneath our feet. Even as the United States has been attempting to stop or divest from renewable energy sources, there’s one kind of baseload power that doesn’t make anyone mad: geothermal. So this week we’re talking not just geothermal, but next-generation geothermal . My guest is Cindy Taff , CEO of Sage Geosystems , a company developing fle...

This week on Everybody in the Pool , we’re examining the seemingly humble—but absolutely critical—piece of hardware that could accelerate electrification, unlock virtual power plants, and save homeowners thousands of dollars: the electrical panel. My guest is Arch Rao , founder and CEO of Span , a company building smart electrical panels that replace your old breaker box with real-time power manag...

This week on Everybody in the Pool, we’re rethinking how clothes, shoes—and even car interiors—get made without plastic. My guest is Maria Intscher-Owrang, CEO and co-founder of Simplifyber. Her innovation takes plant fibers + water, then forms finished 3D shapes in a single step—skipping spinning, weaving, cutting, and sewing.  We get into: What’s broken about fossil...

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 b...

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 buddi...

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 ventur...

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 fa...

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...

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 ca...

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...

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 H...

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 . Wärts...

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 . H...

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 choi...

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...

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...

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...

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...
