Abstract:
1. A shade, comprising: a pair of spaced members held together by a pair of bridging members, a first bridging member coupled to the spaced members proximate one end thereof and a second bridging member coupled to the spaced members proximate a second end thereof, the pair of spaced members conjointly having an elliptical cross-sectional shape; a mounting bracket extending from the shade for mounting the shade to a building; a turbine with a plurality of blades extending at least partially across the space between the pair of members, rotatably coupled to the shade and positioned between the spaced members with the rotational axis parallel to the direction of extension of the spaced members between the first and second bridging members, opposing surfaces of the pair of spaced members defining a hollow having an interior curvature approximating the circumference of the circle traced by the turbine blades when the turbine is moved; the turbine capable of moving in response to moving air; and an electric generator coupled to the turbine, the generator capable of generating electricity when the turbine is moved.
