I'm aware that fusion is an achievable state (I follow ITER progress to some extent, seemingly alone among most nerds) and did read the wikipedia page. I guess I just find myself overwhelmed any time someone starts giving the sales pitch on their uniquely-probable break-even fusion system. The LLNL thing, for example ... I dunno. I guess it's just a hazard of the territory. Energy systems are full of snake oil salesmen at every level, it's so hard to tell who's even working in good faith. Solar, fuel cells, bioethanol, all are like this; why should fusion be any different?
