Abstract: The Air-Water Power Generation System utilizes the temperature differential between warm air and a surface cooled by water evaporation. To enhance the temperature differential, the air that evaporates the water is first cooled by releasing heat to boil the working fluid in a boiler and then is cooled further by a counter-flow heat exchanger before the air enters the condenser where a water film is evaporating. The air then becomes colder as the water evaporates in the condenser, and this provides the cooling to condense the working fluid. Finally, the cold air flows out of the condenser and flows back through the counter-flow heat exchanger to provide the cooling of the air flowing from the boiler.
