Publication Date: 2015.06.02 AELLA

AI summary

The invention describes a method of generating electrical power utilizing hot surface air as the heat source, high atmosphere as the heat sink and a microwave beam aimed upward providing updraft to initiate and control the large-scale air circulation. The frequency of the microwave beam is centered at approximately 60 GHz, within the absorption band of molecular oxygen, so as to result in beam penetration to an altitude of several kilometers. The power plant comprises a high-power microwave source, e.g. a bank of gyrotrons, one or more turbine-generator sets, and—optionally—a condenser/cyclone (if on a floating platform). The plant can also provide clean water from condensation out of humid, sea level air. The plant could also be used to remove atmospheric carbon dioxide from large quantities of air. The dynamic chimney produced by the microwave beam could alternatively be deployed in conjunction with a solar heat power plants, industrial chimneys, and cooling towers of conventional power plants to increase their effective height.
