It's a bargain. Even one billion US$ per day for the bombs, would be like nothing. We are talking about the energy output comparable with all the others (coal, oil, gas, nuclear, hydro ...) combined!
Not necessarily. Plutonium has about 90 TJ/kg energy density. At $500/g, that comes out to about 180 MJ/$, or 2 c/kWh. That's only a bit below half of coal's 4.63 c/kWh. And this is only for the fuel! If you were to go the all-plutonium route, it would probably wind up being more expensive than coal.
High-yield fusion would be another matter.
This thread is intended to provide a space for 'crazy' ideas. Ideas that spontaneously come to mind (and feel great), ideas you long wanted to tell but never found the place and time for and also for ideas you think should be obvious and simple - but nobody ever mentions them.
