Do you have a source for that? I can only find info about it being used for fusion.
hmm, I guess I'm wrong. I read about helium-3 a long time ago and I must have mistaken the purpose. I guess helium-3 is a byproduct of fission and can be used for fusion, but the energy cost to produce it in this manner is massive and isn't sustainable.
Helium-3 is filtered out by the atmosphere so very little of it occurs naturally on earth, the lunar surface was the best/easiest place to mine for it.
