Abstract
Abstract A transparent panel enclosed tower provides a confined space for solar heating air. An upright wind turbine, mounted on the tower top, communicates with the tower enclosed space. As the solar heated air expands and becomes lighter it is displaced by cooler atmospheric air at the bottom of the tower creating a turbine driving thermal updraft in combination with wind energy driving the turbine. The turbine includes an axial drive shaft driving a gear train in turn driving an electric generator, or the like.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
A thermal air and wind powered electric current generating system, comprising: a tower having a plurality of upwardly converging legs and having a centrally open platform secured to the upper end portion of the legs; a plurality of light admitting wall forming panels enclosing said tower for forming a thermal air passageway, the lowermost edge of the lowermost panels being spaced above the surface of the earth a selected distance; a thermal air and wind driven turbine mounted on said platform in communication with the interior of said tower, said turbine having a drive shaft projecting downwardly through said platform coextensive with the tower; a section of helically wound sheet material extending radially inward from the tower walls substantially coextensive with the tower for inducing a cyclonic action on thermal air moving toward said turbine; and a generator operatively connected with said drive shaft.
Claim 2
Dependent Claim
