Abstract
A wind powered rotatable vent includes an annular rotatable louvered panel axially rotatable about a shaft and an impeller disposed in spaced underlying relationship with respect to the rotatable louvered panel and rotatably secured to the shaft. A fixed collar underlies at least a portion of the rotatable louvered panel and a brace which is rotatably secured to the shaft has first arms secured to an upper portion of the rotatable louvered panel and second arms secured to a lower portion thereof. The collar and rotatable louvered panel define a passageway for flow of air therethrough. The rotatable louvered panel is structured to rotate responsive to wind impinging thereon and responsive to air flowing upwardly through the impeller in the passageway.
