Tritium, Nuclear Stockpiles, and Fusion Fuel Dynamics

In this episode of Crazy Wisdom, host Stewart Alsop talks with Rob Meyerson, co-founder and CEO of Interlune and former president of Blue Origin, about building the next phase of the space economy—from mining Helium-3 on the Moon to powering quantum computing and future fusion reactors on Earth. They explore the science behind lunar regolith, cryogenic separation, robotic excavation, and how private industry is rekindling the optimism of Apollo. Rob also shares lessons from scaling Blue Origin and explains why knowledge management and intuition matter when engineering at the edge of possibility.

Key Insights

1. Helium-3 as a Lunar Resource: Rob Meyerson explains that Helium-3, a rare isotope on Earth but abundant on the Moon due to billions of years of solar wind implantation, could power future fusion energy and enable cleaner, more efficient energy sources. Interlune’s mission is to commercialize this resource, beginning with robotic prospecting and extraction missions.
2. The Science of Lunar Regolith: The Moon’s regolith—the dusty surface soil—acts as a natural collector of solar wind gases like hydrogen, helium, and helium-3. Meyerson describes how Interlune identifies promising mining locations using data from NASA’s Lunar Reconnaissance Orbiter and the presence of ilmenite, a titanium-rich mineral that traps more Helium-3 than other regions.
3. Cryogenics and Quantum Computing: Helium-3 is essential for dilution refrigerators that cool quantum computers to millikelvin temperatures, colder than any place in the universe. Meyerson highlights a new commercial contract with Bluefors, a Finnish cryogenics leader, to supply Helium-3 starting in 2028—proving the economic case for lunar resource extraction.
4. Fusion Energy and Strategic Supply: While today’s fusion reactors rely on tritium and deuterium, Helium-3 could be the next-generation fuel—safer and more efficient. With tritium decay from aging nuclear stockpiles as the only current terrestrial source, Interlune’s lunar supply could fill a critical gap for future clean-energy systems.
5. Building Lunar Infrastructure: Interlune’s long-term vision extends beyond Helium-3 to producing rocket propellant, metals, and industrial materials on the Moon. By developing cryogenic separation and excavation systems, they aim to enable a self-sustaining “in-space economy” where resources mined in space fuel space-based operations.
6. AI and Autonomy in Space Mining: Artificial intelligence and advanced sensing will guide robotic harvesters on the Moon’s harsh terrain. AI will also analyze imagery and soil data to map Helium-3 concentrations and manage knowledge across missions, turning data into operational insight.
7. Lessons in Leadership and Scale: Drawing from his 15 years leading Blue Origin, Meyerson stresses the importance of documentation, mentorship, and maintaining technical continuity as teams grow. He contrasts Apollo’s lost potential with today’s resurgence of private space ventures, expressing deep optimism for U.S. innovation and the rebirth of lunar industry.
