Re: Ethanol mogas

The physical details of the process may be a bit murky, but the idea that
the temperature of the engine exhaust and the engine itself would be lower
gives a bigger DeltaT that should be converted into mechanical energy to
pull the plane.

2. steam expansion in combustion chamber adds volume (ie: power).

This sounds dubious to me. It sounds like a violation of second law of
thermodynamics. It takes energy to turn water into steam, and that
steam gives that energy back by expansion, but not more than the energy
it absorbs to vaporize in the first place.


They could be arguing that the heat needed to vaporize the water would
otherwise have been lost anyway.... into the exhaust gases, or into
heating the metal of the engine, for example.
