Edit, oh, megawatt-years. I misread. But it would still take a long time to be a popular source of power. And we would have to manufacture electric cars, and find a wayto store the power for them. And find a way to dispose of the power packs when they have run there usefull lifespan. Oh, and they have to be cheap enough for the average american.

So, let's just sit here and tap our toes untill that happens, shall we?
