E81: This carbon removal tech is literally rocket science

Ep. 81

This week on Everybody in the Pool, Molly Wood talks with Brad Hartwig, co-founder and CEO of Arbor Energy. Brad shares his remarkable journey from SpaceX rocket engineer to climate tech entrepreneur, developing technology that transforms waste biomass into carbon-negative energy using rocket propulsion principles. Yep, you read that right. A guy who used to want to be an astronaut woke up one day and realized this planet was the place to put his energy. Find out how Arbor’s tech could replace fossil fuel plants while simultaneously removing carbon from the atmosphere.


Show Highlights
  • Brad's transition from aerospace engineering at SpaceX to climate tech after witnessing California wildfires firsthand
  • How Arbor Energy's technology uses "oxy combustion" (inspired by rocket engines) to generate clean electricity while capturing carbon
  • The system produces no emissions - only pure CO2 (for sequestration) and clean water
  • Potential to replace up to 60 gigawatts of coal and natural gas plants in the US with carbon-negative power
  • Uses only waste biomass from agriculture, forestry, and potentially municipal waste
  • Economic benefits for wildfire prevention through monetizing brush clearing
  • First commercial deployment targeted for 2027

  • 94. E94: Ahmad Ghahreman: Recycling rare-earth metals, America’s only backup plan

    33:47||Ep. 94
    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, including things like laser guidance systems, missiles, and jet engines. And China controls pretty much the entire market — and, since April, has stopped almost all shipments of metals and magnets!Discover how Cyclic Materials addresses the critical challenge of recycling rare earth metals—essential for a sustainable, electrified future. Ahmad shares his journey from hydrometallurgy to developing innovative processes that extract high-value metals from discarded goods. As electrification accelerates demand, understand why recycling these metals is both an environmental imperative and an economic necessity.Key PointsRecycling Importance: Emphasizing the need to recycle rare earth elements like neodymium and dysprosium, critical for manufacturing electric motor magnets.Technical Challenges: Unpacking the complexities of extracting these metals and how Cyclic Materials develops solutions to overcome these hurdles.Geopolitical and Supply Chain Insights: Ahmad’s perspective on the implications of locally producing these critical metals in North America and Europe, enhancing supply chain resilience.Resources & LinksVisit Cyclic MaterialsConnect with Ahmad Ghahreman on LinkedInListen to all episodes: Everybody in the PoolSubscribe to the Everybody in the Pool newsletterGet an ad-free experience: Become a MemberHelp us spread the word about sustainable solutions!Please subscribe and share Everybody in the Pool with your friends!We value your feedback and inquiries: Contact usExplore how innovative recycling solutions are vital for a cleaner, sustainable future.

  • 93. E93: Rev Yearwood on telling climate stories to everyone

    36:29||Ep. 93
    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 and Molly talk about putting the climate crisis in a language everyone can understand, why there aren’t any hip hop songs about climate change (yet?), and how Earth is like a spouse we need to stop taking for granted.LINKS:Hip Hop CaucusAll episodes: https://www.everybodyinthepool.com/Subscribe to the Everybody in the Pool newsletter: https://www.mollywood.co/Become a member and get an ad-free version of the podcast: https://everybodyinthepool.supercast.com/Please subscribe and tell your friends about Everybody in the Pool!

  • Bonus: Processing climate change through fiction

    41:32|
    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 interviewed the Harvard professor and scientist Naomi Oreskes. She is known for her climate change activism, for nonfiction works on coordinated disinformation, and for trying to communicate science to the masses — which led her to co-author a work of fiction called The Collapse of Western Civilization. We spoke with her about knowing what’s coming, how to stop it, how to win people to your side, and how sometimes fiction can tell better stories than science.LINKS: The Futureverse podcastNaomi OreskesThe Collapse of Western CivilizationAll episodes: https://www.everybodyinthepool.com/Subscribe to the Everybody in the Pool newsletter: https://www.mollywood.co/Become a member and get an ad-free version of the podcast: https://everybodyinthepool.supercast.com/Please subscribe and tell your friends about Everybody in the Pool!

  • 87. E87: Re-air: Mill, the prettiest composter on the block

    23:43||Ep. 87
    This week on Everybody in the Pool, we couldn’t let Earth Month pass without one last conversation about consumer action and devices—and this week, we’re re-airing a conversation from someone who’s an expert at designing things that people want to buy. Matt Rogers is the co-founder of Mill, a kitchen appliance that turns food waste into dried, odorless grounds that consumers drop in the mail and that get upcycled into chicken feed. And Matt just happens to have also co-founded a little company called Nest, which has been a powerful driver of energy efficiency. He and Molly talk about how food waste is the unexpected giant emitter that requires major behavior change, and sometimes, a sexy gadget is just what you need to make that change.RESOURCES & LINKSMillMill vs Lomi via Architectural DigestAll episodes: https://www.everybodyinthepool.com/Subscribe to the Everybody in the Pool newsletter: https://www.mollywood.co/Become a member and get an ad-free version of the podcast: https://everybodyinthepool.supercast.com/Please subscribe and tell your friends about Everybody in the Pool!
