Patent ID: 8482148

Claim:
A solar thermal power generation apparatus comprising: a turbine rotatable around a vertical axis; a power generator driven by the turbine; a funnel disposed along the vertical axis so as to house the turbine and having an intake port at a lower end of the funnel; a transparent box body disposed so as to surround a lower portion of the funnel and having an air intake port at a position being lower than the intake port; and a heat collector disposed in a standing manner at a distance between the box body and the funnel wherein an upper end of the heat collector is at a position being higher than the intake port; wherein, after air having flown from the air intake port into an inside of the box body is heated by the heat collector, the heated air becomes an updraft flowing from the intake port into an inside of the funnel to rotate the turbine, which causes the power generator to generate power, and wherein the funnel comprises an introducing side cylindrical portion constituting the lower portion of the funnel and facing the inside of the box body and the exhaust side cylindrical portion positioned in an upper portion of the box body, wherein the exhaust side cylindrical portion has a vibration plate and a piezoelectric element and the vertical axis has wheels each being contactable with the vibration plate.
