Helium-3 is abundant on the moon
The discussion about using lunar Helium-3 for fusion reactor fuel has been going on for decades. The Solar Wind has saturated the Moon with Helium-3 because the moon has no magnetic field. Helium-3 could provide safe fuel for a fusion reactor because it is not radioactive and produces no dangerous waste. It's worth about $4 billion per ton, but would be very technically challenging to extract.
Lots of science fiction written about it. And the excellent alternate timeline show on Apple+, For All Mankind, has civilization powered by Helium-3. And of course the former fossil fuel workers are protesting lost jobs!
