I have a better idea. If we attach billions of hamster wheels to tiny generators over an area the size of Africa, they could power the entire world. They would have the great advantage of not needing scarce rare earth minerals. They would be more sustainable because they can be made of wood which is renewable. The only disadvantage I can see is that I might end up in the same lunatic asylum as the guys who thought this one up.
