He3 (Helium-3)

Helium-3 (He-3) is a rare isotope of helium with two protons and one neutron. It’s non-radioactive and stable, used in specialized scientific and medical applications. In fusion research, He-3 is considered a promising fuel because its atoms release a large amount of energy when fused with deuterium, producing minimal radioactive waste. It’s also found naturally on the Moon's surface, embedded in lunar soil, making it a potential resource for future energy production. Its scarcity on Earth makes it valuable and important for advancements in clean energy and advanced physics experiments.
