The US in some ways has been the best. Who figured out shale gas? Although that wasn't a good thing [for CO2 levels], it was very innovative. It's led to low-cost energy. Who figured out nuclear power? Largely the United States. Once you get past the steam engine, which is mostly British, then the US has been at the center of most of the energy things that have happened.

There was a concept a long time ago that you would do a different type of reactor called a "fast reactor," that would make a bunch of another element called plutonium, and then you would pull that out, and then you would burn that. That's called "breeding" in a fast reactor. That is bad because plutonium is nuclear weapons material. It's messy. The processing you have to get through is not only environmentally difficultly, it's extremely expensive.

Who in their right mind would ever need more than 640k of ram!?
