Patent
·
OSTI ID:6292019
A base frame supports a horizontal shaft having one or more wind driven members secured thereon. Each of the wind driven members includes a shaft of light-weight framing and plurality of elongated longitudinally extending light-weight vanes having wind engaging surfaces. The vanes have a wind driving position on one side of the shaft and a return position of the other, and light-weight wind deflectors disposed at the front of the frame protecting the return position of the vanes from the wind. The wind deflectors are angularly adjustable whereby the deflected wind flowing off the longitudinal edges thereof is selectively directed against the vane surfaces in their driving position. The shaft has an output for operating a selected driven apparatus such as a generator. The base frame is rotatably supported on a pivot for selected adjustment relative to the wind.
