Abstract:
1. A Magnus type wind power generator comprising a horizontal rotary shaft that transmits a rotation torque to a power generating mechanism, a plurality of rotary cylindrical columns that are disposed radially from said horizontal rotary shaft, and driving motors that rotatively drive said respective rotary cylindrical columns about axes thereof, wherein Magnus lift generated by interactions between the rotations of said respective rotary columns and wind power is caused to rotate said horizontal rotary shaft to drive said power generating mechanism, wherein each said rotary cylindrical column has a rib wound around said rotary cylindrical column in a continuous spiral shape extending from an outer peripheral surface of said rotary cylindrical column, said rib extending substantially along the length of the rotating column, and wherein said rib generates an air flow component at least parallel with an axis of said rotary cylindrical column upon the outer peripheral surface of said rotary cylindrical column, so as to increase the Magnus lift.
