That's right it has a water vapour phase. These are all top ideas, don't get me wrong. However would they last 100,000kms, 200,0000kms, 300,000kms... Would you drive a car that had an engine that required a rebuild every 20,000-50,000kms? The first rotaries that came out in the 70's lasted about this long on average.
Reliability is a very big thing. Current Otto cycle, crank driven piston engine is very reliable and relatively cheap to manufacture and warrant.
