Patent ID: 7621129

Claim:
A geothermal power generation system comprising: a first air inlet located at the surface of the earth; air entering said air inlet at an ambient temperature; a subterranean chamber located beneath the surface of the earth; ductwork located in said subterranean chamber; said subterranean chamber having a naturally occurring geothermal temperature; a first insulated conduit defining a first flow path for fluidly connecting the first air inlet to said ductwork in said subterranean chamber whereby the air entering said first air inlet passing through the ductwork is heated substantially to the geothermal temperature; and said ambient temperature is substantially cooler than said geothermal temperature; whereby a fluid flow is induced between the air entering said first air inlet at said cooler ambient temperature, and the air passing through the ductwork that is heated to said geothermal temperature, and, a turbine generator located in said first flow path that is powered by said induced fluid flow, said geothermal power system further including a tornado/vortex engine that includes a cyclonic chamber wherein warm air from the ductwork is introduced into a lower side wall of the cyclonic chamber at a plurality of hot air inlet ports, and, said tornado/vortex engine further including a second insulated conduit defining a second flow path for admitting cool ambient air from a second air inlet, located at the surface of the earth, to said cyclonic chamber; said second flow path opens into the cyclonic chamber in a central location near a bottom portion of the cyclonic chamber, whereby the warm air entering the side wall of the cyclonic chamber rises and collides with the cool ambient air entering the center of the cyclonic chamber that is descending to produce a high cyclogenesis effect.
