I’d like to see what Eric Lerner has to say about this… it sounds really cool. Focus fusion is partially supported by JPL, and, before spending cuts, by NASA as a potential breakthrough spacecraft propulsion technology. There is an article somewhere on the site about it. It would be great if the emdrive could be coupled to a PFF reactor. I just wonder if the emdrive would be a better solution, given what the FF can do on its own.
