Mining Helium-3 on the Moon to Fuel Future Fusion Economies

The Moon's surface is laced with helium-3, a rare isotope blown there by the solar wind over billions of years. On Earth, helium-3 is almost nonexistent. In a fusion reactor, it would burn cleanly and efficiently. The combination — rare isotope plus future energy technology — is why the Moon is already at the center of the 21st century's resource race.
