Vertical axis wind powered generator

An apparatus for generating electric power from wind comprising:

• a base;
• a pair of upstanding, generally parallel, spaced apart walls rotatably mounted on said base and defining an inlet end and an outlet end for wind;
• means for generating electric power mounted on said base and having an input shaft;
• a vertical axis cylindrical rotor having a plurality of wind driven vanes, and mounted on said base between said walls, and having an output shaft coupled to rotate said input shaft;
• an inner modulator rotatably mounted on said base inside said rotor and selectively movable for controlling wind flow through said rotor;
• and
• an inlet modulator rotatably mounted on said base at said inlet end and selectively movable for controlling wind flow to said rotor.

• and
• an inlet modulator rotatably mounted on said base at said inlet end and selectively movable for controlling wind flow to said rotor, said inlet modulator including a generally vertically extending, curved planar surface pivotally attached to an inner surface of one of said walls adjacent the inlet end.
