Thread Name: BS: nuclear fusion
Subject: RE: BS: nuclear fusion
I can't remember which lab had achieved positive power for a few seconds, but it may very well have been Lawrence Livermore. Saw it on TV too, at least 8 humongous lasers in a radial pattern firing at one small spot.

Wiki on Fusion gain factor which claims the Tokamak in the UK has the best record currently. Q=0.67 but it says that Q=5 is the target for positive power because of losses, unusable energy and input power.

A notable point is that nuclear fusion produces neutrons and some alpha particles - er - radiation however you describe it. The interception of neutrons (mostly) is the method of generating heat and thus electricity.
