Variable wing venturi generator
View Patent ↗A variable wing venturi generator and a housing for the same are presented. The wings are variable in that their relative position may be changed and optimized to maximize airflow through a turbine and generator contained between the wings. The invention allows for improved efficiency in wind generation. The device accelerates wind speed between a pair of adjustable venturi wings and is especially suited for low wind conditions.
1. An wind powered electric generator comprising:
a) a first rectilinear plane with a top surface, a bottom surface and a front edge, a rear edge and two side edges, the front and rear edges being straight and the rectilinear surface curved upward slightly such that the side edges are slightly curved from horizontal thereby forming a wing-like surface,
b) a second rectilinear plane with a top surface, a bottom surface and a front edge, a rear edge and two side edges, the front and rear edges being straight and the rectilinear surface curved upward slightly such that the side edges are slightly curved from horizontal thereby forming a wing-like surface,
c) The first rectilinear plane placed above and substantially overlapping the second rectilinear plane the planes held in position with brackets such that air can flow between the first rectilinear plane and the second rectilinear plane,
wherein a space between the first rectilinear plane and the second rectilinear plane is larger at the front edges of the rectilinear planes than at the rear edges of the rectilinear planes, and,
d) sidewalls that are located at the side edges of the rectilinear planes thereby forming a rectangular space enclosed on four sides with openings at either end to allow air flow through the rectangular space,
e) a turbine located in the space between the first rectilinear plane and the second rectilinear plane and oriented such that the turbine rotates when air flows between the surfaces,
f) an electric generator attached to the turbine such that the rotation of the turbine causes rotation of the shaft of the generator thereby producing electric power output from the generator.
