ABSTRACT:
An apparatus for generating electric power from wind includes a base, a pair of upstanding, generally parallel, spaced apart walls rotatably mounted on the base and defining an inlet end and an outlet end for wind, an electric power generator mounted on the base and having an input shaft, and a vertical axis cylindrical rotor having a plurality of wind driven vanes and mounted on the base between the walls, and having an output shaft coupled to rotate the input shafts. A curved inner modulator is rotatably mounted on the base inside said rotor and is selectively movable for controlling wind flow through the rotor. An inlet modulator is rotatably mounted on the base at the inlet end and is selectively movable for controlling wind flow to the rotor. A first generally planar director is pivotally mounted on an outer surface of one of the walls and a second generally planar director is pivotally mounted on an inner surface of the other one of the walls and both directors are responsive to the wind for positioning the inlet end toward the wind.
