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.
You have to have fusion. With fision you have to clean too much.
And the OP wanted the fusion as well.
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.
