Abstract Text:
As the fusion community prepares for deuterium-tritium (D-T) reactors, it is crucial to explore the potential of He-3 as a future fuel source. Unlike D-T fusion, which generates significant neutron radiation and long-lived waste, D-He-3 fusion offers an aneutronic alternative, minimizing radioactive byproducts and simplifying reactor design. However, the feasibility of He-3 extraction from the Moon has often been questioned. Our primary goal is to educate the fusion community on how advancements in lunar resource utilization make the practical extraction and return of He-3 to Earth a reality.
Lunar Helium-3 Mining, LLC is leading the effort to work with, rather than against, the lunar environment to develop sustainable approaches for helium-3 extraction. He-3 exists at ultra-low concentrations—approximately 1 ppb—in the lunar regolith, a material characterized by its sharp, spiculated nature and its resistance to traditional Earth-based mining techniques. By adapting to these conditions through dust mitigation and advanced processing methods, we are demonstrating how practical solutions can address the challenges of lunar resource extraction.
This presentation focuses on the broader implications of He-3 for the fusion community, rather than the specifics of our proprietary technologies. For example, D-He-3 fusion’s higher ion temperatures and plasma confinement should be considered early to avoid costly retrofits.
Lunar He-3 extraction hinges on three factors: advanced fusion technology, lower space transportation costs, and Moon-adapted extraction methods. With these elements progressing in parallel, He-3 mining is moving from a theoretical concept to a practical solution for fusion energy.
By presenting these insights, we aim to help the fusion community understand the potential of using He-3 so it can be considered as early as possible in future reactor designs.
