ABSTRACT:
A vertical axis wind-driven rotor which combines effective utilization of the energy in a strong wind with maintenance of effective torque at low wind speeds. In one embodiment, the rotor has a reservoir of liquid located near its base. A plurality of tubes radiate outwardly from the reservoir along the base, then rise upwardly along the outer edges of the rotor vanes. In another embodiment, a Savonius type rotor is modified so that the vanes are hinged, and the trailing edge of each vane weighted, whereby in a wind the rotor starts in a fully open condition and automatically feathers itself at high wind speeds.
