There is one thing that I cannot understand regarding the supposed efficiency of a compressed air engine.
When you compress air it generates heat. Between the time you compress the air and the time you use this air to power a vehicle that heat dissipates away. That is a very large loss of energy.
It reminds me of the gasoline ICE. Most of its inefficiency is due to the wasted heat which is generated burning the gasoline.
Can someone shed some light on this issue for me?
