I’d be curious to see some solid analysis of the economics of harvesting lunar He3 for use in terrestrial fusion plants. My guess is that the mining, He3 extraction, and transport costs would vastly outweigh any economic advantage of using He3 versus conventional D-T fusion reactions, much less pB11. I’d wager that, if we had such in-space industrial capabilities available, it would make far more sense to construct solar power satellites instead.
