...
a couple years ago i hooked an air hose from my garage air compressor to a weed wacker engine (small 2 stroke) and gave it a spin and it took off and that was at 140 psi (10bar?)
i wonder how my motorcycle would run with a scuba tank supplying air
A similar concept was invented about 200 years ago.
Just that it didn't use compressed air, but compressed, gaseous water (AKA steam):
the steam engine
Steam locomotives normally operate with a boiler pressure of 10-13 bar.
