Abstract: The wind operated generator has a housing having a shaft opening for receiving an outer turbine tube shaft extending longitudinally through the shaft opening. An inner turbine has an inner tube shaft extending longitudinally through the outer tube shaft. Roller means are provided for supporting the outer and inner tube shafts within the housing. Roller ring means are interposed between the inner and outer tube shafts and the housing for limiting axial movements between the outer and inner tube shafts with respect to the housing. Magnetic means are carried on outer and inner tube shafts with corresponding juxtaposed electromagnetic pick-up means to provide an electrical output, the inner turbine means having scroll-type vanes directing a coplanar flow of air to actuate the outer turbine having open-ended box-type vanes.
