The guys at Focus Fusion have provided their take on that Robert Bussard video that's been making the rounds. Their impression is that his approach looks promising.

Their own approach is somewhat different technically, but either one, if successful, would enable the same sort of technological revolution.

Boron fusion. Clean, inexpensive, inexhaustible power.
