Jim, that's why I said we are not ready yet. Of course it will take decades for the changeover. It will take a dozen years for the new nuke plants to start to get online anyway. By than I am willing to bet battery technology (or capacitors) will be WAY ahead of where they are today.

The nice thing about nuke/ electricity is as demand increases, the infrastructure can be slowly upgraded. If we adapt a hydrogen economy, MASSIVE infrastructure needs to be built upfront. Pretty much the same for ethanol. With electricity, you only need to add lines and plants as demands increase.

Bjorn is right though, we will be buying engine sounds from itunes to play through the radio.
