I can't see it keeping cool either. The method of displacement might
be different, but exothermic BTU are just that, exothermic.
850 HP of heat, is a lot of heat and in a concentrated package like
that?

Technically, any heat (or sound) produced by an engine is wasted energy.
An ideal engine would produce no heat or sound, having converted all the
chemical energy into mechanical energy.

Well, not totally, the heater uaes the engine heat to warm the car in the
winter.


Given that current car engines are something like 35% efficiency, there is
a lot of room for improvement.


Exactly, typically electricity is 4 times more efficient to power a car.
Oddly it is cheaper and uses less fuel to create electricity to power that
car than it is to use that fuel directly to power the car. Today's car
engines are an inefficient design to convert fuel into immediate energy.
