Wasn't suggesting 100% efficient batteries, free electricty or any of that stuff. Only trying to illustrate a point about efficiency - in nonengineering terms. I know I already discussed somewhere efficiencies for power plants, distribution, etc. (I'm too tire to look it up right now, it's midnight here)

I try not to write thesis on this site - I don't like to read them (and ususally don't), and I wouldn't expect others to either.

The point is efficiency and system improvements. That's what an engineer does, tries to make improvements. So we analyze systems to do this. Hybrids work. Pure electric cars don't. By the way I did submit a paper to the DOE on hybrids, but not for 100% efficient batteries.

Where did diesel fuel come from?

Waste oil.
