A high efficiency wind power machine is disclosed which is particularly well suited for large-scale, commercial conversion of wind power into electrical energy. The wind power machine of the present invention employs highly efficient wind-to-electric power conversion modules which may be interconnected to form a large-scale power converter. The individual modules employs flip-flop wind blades which travel in an oval path and are carried by traveling chains. The blades interact with the impinging wind stream at two points, thus increasing the overall efficiency of the conversion modules.
