Abstract

Air and water are provided in a solar collector and heated by the solar collector to provide warm humid air which is transported past a boiler in a closed cycle power system. The boiler is positioned at an elevation above that of the solar collector. A working fluid in the boiler of the power system is heated by the warm humid air, whereby the working fluid is pressurized and the warm humid air is cooled causing water vapor to condense from the air. The energy of the pressurized fluid is converted into a useful form of energy, thereby expanding the working fluid which is transported to a condensor of the closed cycle power system where the working fluid is cooled by water pumped from a lake. The cooled working fluid is recycled through the boiler. The water that is condensed from the humid air is collected and recycled through the solar collector, at least partly as a result of the low density of the rising warm air moving from the solar collector to the boiler in relation to the higher density of the descending cooled air moving from the boiler to the solar collector.
