My thinking was a bit different since I never got to a physics class..A Redhead got in the way..

I was taught as a youngster that there isn't a "perpetual motion machine" ie. a machine that will run itself.

Knowing this it falls into place that using one type of fuel to make another type of fuel one will lose power in the exchange.

SO: Using gasoline to make elecrticity, the lectric output will accomplish less than that same amount of gasoline could accomplish.. Meaning the task should have been done with the gasoline in the first place.

But thanks anyway for the explaination..
