Inevitable

Dr. Stephen Beaton is Co-founder and CEO of Circularity Fuels, which develops compact reactors that turn waste carbon streams into high-value fuels and chemicals. Rather than compete with fossil fuels from the start, Stephen identified high-purity methane for lab-grown diamonds as a beachhead market—where Circularity’s product is 80–90% cheaper than incumbents while proving the core technology needed for clean liquid fuels.Stephen earned a chemistry PhD at Oxford and built deep expertise in synthetic fuels during his U.S. Air Force career, including overseeing jet fuel quality control in the Middle East and launching the Air Force’s e-fuels program. His insight: build a fuels company that doesn’t begin with fuel.Today, Circularity Fuels operates demonstration reactors in diamond facilities and is scaling toward biogas-to-SAF production using the same reactor platform. The company has raised $3M in venture funding, including from DCVC, plus $5M in grants from ARPA-E, NSF, and the California Energy Commission. MCJ is proud to be an investor.Episode recorded on Aug 12, 2025 (Published on Sept 16, 2025)In this episode, we cover: [03:09] Dr. Beaton’s background in clean fuels[07:31] His work with Air Force petroleum in the Middle East[10:12] A brief overview of hydrocarbons[13:08] ESAF as resilience for Pacific operations[16:22] What e-SAF really means and why it matters[19:24] Circularity Fuels’ origin story[21:20] The company’s three principles[23:04] High-purity methane for diamonds as a beachhead[27:46] Recycling diamond exhaust with microwave-sized reactors[30:40] Building a fuel company without fuel as the initial product[34:35] Hardware sales vs metered methane service model[39:05] Biogas-to-SAF pathway via Fischer-Tropsch[42:38] Circularity’s progress to date[44:01] Competing with fossil jet and carbon removals[48:41] How Circularity secured non-dilutive funding Enjoyed this episode?

Marc Tarpenning is Co-founder of Tesla and a venture partner at Spero Ventures. In 2003, Marc and Martin Eberhard saw two signals: GM killed its beloved EV1, and Californians snapped up Toyota’s Prius despite its compromises. They realized the market was ready for an electric car that was better than gas, not worse. Their breakthrough: 7,000 off-the-shelf laptop batteries powering a sports car that outran a Porsche and drove over 200 miles. The Tesla Roadster was born, before Elon Musk joined the company.Marc shares how his time in Saudi Arabia exposed him to oil dependence, how NuvoMedia taught him about the pace of battery improvement, and why a software mindset helped Tesla out-innovate incumbents. Now at Spero Ventures, Marc backs founders building solutions that are both economically compelling and environmentally vital, and explains why, to him, EVs have already won.Episode recorded on Aug 12, 2025 (Published on Sept 9, 2025)In this episode, we cover: [05:58] Marc's experience fixing software projects in Saudi Arabia[07:06] Why TELO’s compact electric pickup makes sense[09:09] Marc's Star Trek optimism versus Blade Runner dystopia[10:29] On founding NuvoMedia and the first e-book readers[17:40] Brainstorming EVs after the dot-com collapse[20:25] Prius demand proves customers value efficiency[22:18] Reducing oil dependence as national security[24:46] Roadster powered by 7,000 laptop lithium-ion cells[30:28] The Tesla launch playbook[32:14] Acceleration as the hook for high-end EV buyers[37:20] Early interactions with Elon Musk at SpaceX office[40:11] Lessons from early Roadster builds[43:36] Vertical integration only where it truly differentiates[48:15] Why EVs are inevitable[50:30] Marc's thoughts on Tesla today Enjoyed this episode?

Dr. Michael Mann is Presidential Distinguished Professor of Earth and Environmental Science at the University of Pennsylvania. He also serves as Director of the Penn Center for Science, Sustainability, and the Media, and Vice Provost for Climate Science Action and Policy.Dr. Mann first entered the public consciousness in the late 1990s with his "hockey stick graph," a reconstruction of Earth’s climate history over the past 1,000 years. The graph became both a cornerstone of climate science and a lightning rod for controversy. Since then, he has published more than 200 peer-reviewed papers, co-founded realclimate.org, and written five books—most recently, Our Fragile Moment: How Lessons from Earth’s Past Can Help Us Survive the Climate Crisis.Having spent nearly three decades fighting climate misinformation and defending the scientific record, Dr. Mann has witnessed multiple waves of public consciousness around climate change. In this episode, we hear his perspective on how public sentiment has evolved, where we stand today, and his views on what he sees as a coordinated campaign to block climate action.Dr. Mann doesn’t pull punches. He names names, draws direct lines between fossil fuel interests and political actors, and isn’t shy about calling out what he views as bad-faith tactics across the political spectrum.Episode recorded on May 21, 2025 (Published on Jul 22, 2025)In this episode, we cover: ⁠[1:51]⁠ DiCaprio based Don’t Look Up character on Michael⁠[4:26]⁠ Why Michael’s center combines science and media⁠[5:27]⁠ Communication is today’s biggest climate challenge⁠[7:27]⁠ The story and impact of the “hockey stick” graph⁠[13:17]⁠ How fossil fuel interests targeted his work and reputation⁠[15:32]⁠ Russia’s modern climate disinformation tactics⁠[17:22]⁠ Climate denial, delay, doom, distraction, and division⁠[20:26]⁠ Deflection: blame shifted to individual responsibility⁠[21:48]⁠ The progress we’ve made and the need to accelerate solutions⁠[25:17]⁠ Why China may lead in future emissions reductions⁠[29:16]⁠ Methane leaks make gas a major climate threat[33:15] What exactly we’re trying to save on the planet⁠[38:22]⁠ How Project 2025 is erasing climate accountability⁠[40:46]⁠ Which climate science institutions are being dismantled⁠[45:09]⁠ What a livable 2050 future could still look like Enjoyed this episode?

Dr. Mark Jacobson is a professor of Civil and Environmental Engineering and Director of the Atmosphere Energy Program at Stanford University, where he’s been one of the most vocal advocates for powering the world entirely with wind, water, and solar energy. No nuclear, no carbon capture, no fossil fuels of any kind. His research team has created 100% renewable energy roadmaps for all 50 U.S. states and 149 countries, helping shape policies like New York’s clean energy mandate. In this episode, Dr. Jacobson shares his perspective on where we are in the renewables adoption curve and explains why he believes that technologies like nuclear power, carbon capture, and biofuels aren’t just unnecessary, they’re harmful distractions from the clean energy transition he sees as both achievable and urgent.This conversation may be polarizing. While many will agree with Mark's take on renewables and the grid, his firm rejection of other low-carbon tech challenges mainstream climate thinking. We believe these fault lines are worth exploring, even, or especially, when they make people uncomfortable.Episode recorded on June 30, 2025 (Published on July 15, 2025)In this episode, we cover: ⁠[02:32]⁠ Why proposed tax changes threaten renewables⁠[05:45]⁠ Fossil fuel subsidies vs. renewables support⁠[06:29]⁠ China’s rapid clean energy deployment⁠[10:44]⁠ Rooftop solar offsets California’s rising demand⁠[12:20]⁠ Home and utility batteries reshaping grid usage⁠[14:40]⁠ Texas grid inefficiencies and renewables progress⁠[18:21]⁠ Combining wind, solar and batteries[19:26]⁠ Land use myths about wind and solar[22:49] Dr. Mark Jacobson’s background and research⁠[27:23]⁠ How to phase out existing fossil infrastructure⁠[31:36]⁠ Dr. Jacobson’s rejection of carbon capture[36:52] His thoughts on nuclear[42:11] Dr. Jacobson’s thoughts on geothermal[46:19] How he sees the next decade unfolding Enjoyed this episode?

Suvi Sharma is the CEO and Co-Founder at SOLARCYCLE. SOLARCYCLE is an emerging leader in the nascent category of solar panel recycling. The astounding ramp of solar panels deployed across the world rivals almost any technology adoption curve in history, and it's far from over. There were only five gigawatts of solar deployed globally between 2000 and 2005. By the end of 2025, a mere 20 years later, there will be around 2,000 gigawatts of solar deployed globally, and the growth is expected to continue to be exponential. That's billions and billions of panels that collectively make up a few hundred thousand square miles of space. And given the rate of installation, most of these panels are early in their expected lifespans. So, what happens when they do hit the end of life? Surely they aren't going to just be landfilled, right? Right? That's what Suvi's here to about. In this episode, we cover: ⁠ [01:16]⁠ Solar panel deployment vs. end-of-life lag⁠[03:40]⁠ Billions of panels, billions of square feet⁠[05:11]⁠ 1.2B panels produced annually—set to triple⁠[07:06]⁠ Why is now the time to build recycling⁠[08:36]⁠ Who’s responsible for end-of-life?
