I just question your application and assumptions.
You seem to think I can't do math.
Here's some simple math.
(Thermal efficiency of a typical gasoline engine) + ( energy wasted in a typical gasoline engine ) = (Total energy potential of a measure of gasoline )
Making the usual assumption of 30% thermal efficiency, the equation becomes:
30% +70%= 100%
Can you see where the efficiency gains are to be found?
All you have to do is slide some of the value from the second term to the first and there you will find a gain in fuel efficiency.
The problem with your math application is that you assume there is only one way to apply the math. With enough science, you can see the obvious dead ends. With an even deeper understanding of science, you can see some paths around those dead ends.
