I'm really surprised that (AFAIK, haven't checked lately) no billionaire is funding Polywell, focus, and/or other fringe fusion research projects. I know, the odds of these panning out are not great, but if you want to become a trillionaire, seems like these are the kind of lottery tickets that could get you there -- and do a massive amount of good for the world in the process. I can tell you, if I had a few hundred million to throw around, I would be all over these things.
