Right, Tokamaks are hot fusion, I didn't mean to state it quite like that, sorry. Aren't they building one in like France of all places? And did they ever do any more research on photoemission following bubble collapse? That was starting to look promising a few years ago, but I've heard squat since...
Ya, they are building it in France altho most of the industrialized world is chipping in on it. Tokamaks will have huge problems with radioactivity if they ever manage to sustain the fusion for a longer time though.
I think ppl are still doing research on the bubble-energy, altho I think they arent sure if they get a net gain in energy. I think I read somewhere that the energy gain they measured were so low that it's within the margin of error for the measuring instrument.
