Re: Physics 101
100MW is a lot, but these guys are used to dealing with jet engines, which tend to generate that sort of power. Granted, most of that is produced as kinetic energy, but it does start as heat; so if they can produce the power in the first place, I'm reasonably confident they'll find a way to use it.
Then again, those containment walls are frightfully thick, so to get much power through, they'd probably have to be full of cooling channels. Not sure what that'll do to the design, but I'm fairly confident the Lockheed guys have given it some thought. I've only been thinking about it for as many minutes as they have years, after all.
