Abstract: A wind power generator has an arcuate converging-diverging flow passage and a support body that is prolate in shape and is located in the flow passage. The support body is rotatably supported and a plurality of rotor blades are mounted on the support body. The support body and the flow passage define a converging-diverging flow area through which wind passes to drive the support body via the rotor blades.
