If so, then he really shouldn't have sacked his science advisor, who would have told him that you can breed He3 in a lower temperature D-D reactor. You already know the following, but I'm writing this for the benefit of others. IOW the whole idea that you need to e.g. go to the Moon for He3 is mostly invented by science journalists or ScFi authors. A D-D fusion reactor running at less than about 20 keV would produce He3 without consuming much. It would however be a "dirty" reactor so should be operated somewhere out in the desert. Of course if would also produce T which would (depending on operating mode) usually be burnt up immediately producing energetic neutrons. If carefully designed, such a reactor would produce:- 1) He3 2) A lot of power 3) Masses of neutrons that might be used to remediate existing long term nuclear waste, which might even be incorporated into some of the structural components in the form of ceramics, cermets, or alloys. The He3 can then be transported to other "aneutronic" reactors located more conveniently. BTW a little side note on Helion Energy. If they have already started construction on a 50 MW power plant, then they must be quite confident in their ability to burn He3. This implies that they could also burn D-D.
