helium-3 mining

Helium-3 mining refers to the process of extracting the rare isotope helium-3 (³He) from natural sources, such as lunar soil, planetary atmospheres, or gas deposits. Helium-3 is of interest for its potential use as a fuel in future nuclear fusion reactors, which could provide a cleaner and more efficient form of energy production. On Earth, helium-3 is extremely scarce, so much of the proposed research and development focuses on mining it from the Moon, where it has been deposited by the solar wind over billions of years.
