More conspiracy theory. Dribble wants to replace a highly inefficient

This proves this person senile. Piston engines are approx 20% efficient.
80% of the energy in the tank is wasted.

Wrong yet again. Try harder. Look up the efficiency of various types
running at their 'sweet spot' as you want. You might just learn something
for once. But I doubt it.

no, dribble isnt far wrong in practice. Car engines dont run at anything
like the sweet spot' most of the time.




JOOI where is this other energy wasted in heat or emissions or a combo
of both?..

Suppose I have say a 100 kW engine then 25 % of that is useful driving
the wheels energy, so where would or does the other 75 kW go to then
surely not all as heat?..
