In a trial at the National Ignition Facility late last year, 15 kilojoules of energy was released with an input of 10 kilojoules (Nature). Although this is not yet a self-sustaining reaction because the reactor as a whole consumes more energy it is expected that collisions with helium nuclei generated in the reaction will lead to ignition. See the article at New Scientist for more information."

    I know, I know...fusion is only 20 years away. But getting more energy out than you put in (minus the lasers, of course) is a big deal. They still need 2 orders of magnitude to REALLY break even, but then 20 years ago we were 2 orders of magnitude away from fuel input break even.

    You can't rationally argue somebody out of a position they didn't rationally get into.
