ABSTRACT:
A streetlight for illuminating a portion of an adjacent roadway. The streetlight includes three vertical support members with a rotatable axle mounted intermediate thereto. Superposed on the vertical support members is a light assembly. A plurality of wind receptacles, having a hub, at least one support arm and at least one cup shaped wind-capturing device are operatively connected to the axle. The wind receptacles act to harness air current and rotate the axle, which is operatively connected to an electrical generator. The electrical current from the generator is stored in a power storage unit. The streetlight further includes photovoltaic cells for supplying power to the light assembly.
