Abstract: This wind powered cylinder consists primarily of a ground level mounted cylinder, which may be coupled to similar sections for being wind rotated at the lowest possible wind speeds, and it is to be controlled by a hydraulic lift and speedometer means so as to maintain a desired speed. The device includes flexible air vanes movable at their outward ends, for directing the air flow, according to the direction of wind flow, into the device, and a power take-off shaft is secured to the cylinder.
