While we are on the subject; I've read that 1/3rd of the energy in a gallon of motor fuel is wasted as heat through the radiator and exhaust plus air-cooling of other parts that get hot, 1/3rd is wasted by mechanical drag (ever try to hand-crank an outboard motor), and 1/3rd propels the car. Even the last 1/3rd is challenged by the cars weight and air-drag. Finding a way to recapture the wasted heat energy and reduce mechanical drag should help. We could probably heat our homes with the wasted heat energy from our daily commute if we could find a way to bottle it and take it home :-).

We were in England last summer and it appeared to me that the small stick-shift car we were riding in did not have air conditioning or power steering and maybe not even power brakes. They were paying US-$8.00 per gallon for gasoline last year and who knows what they are paying now.
