Just read a post about someone having a cylinder with a sparkplug mounted in it, and a simulated head plate with viewing window.
He pumped in 125 PSI or DRY air, from a painters compressor air supply, and fired the plug. The plasma flame got LARGER.
After a couple days, he repeated the procedure, but, the DRY air was not available, so, he just used normal, "Humid" air
Blew the viewing plate out of the head plate, and scared the hell out of himself
Doesn't sound to me like a LOT of moisture is needed to push a piston down
NO other fuel, just moist air
He will try an engine soon. Just thought y'all might be interested
