Nunley Steam Engine
Internal combustion steam engine converting water to steam in the engine and back to water within the engine. No external steam generation is used.
Horizontal cylinder with piston receives alcohol/water mix followed by an injection of either propane or butane. This ignites to flash the water to steam. Water expands by a factor of 1,600 to power engine. After the cylinder is moved air input takes steam back to water. Thus, a little propane/butane is used making little air pollution.
