A wind-powered drive shaft, the rotary force of which can be used for a variety of purposes, such as to drive a hydraulic pump, the crankshaft for a water pump, or an electrical generator. To a central shaft are attached two or more sets of arms extending radially outward from the central shaft and containing two or more arms each. Preferably the sets of arms are arranged in pairs about the central shaft. Each set of aims has two or more aims. Two or more pivot shaft are rotatably attached to each arm in a set of arms and between vertically adjacent arms a vane composed of light but strong material is connected to each pivot shaft. Attached to one of every two vertically adjacent arms is a stop, said stop being in such a location that the free end of the vane will contact said stop when such free end makes its closes approach to said central shaft. A wind will, therefore, blow the vane open on one side of the central shaft and will blow the vane against the stop, thereby generating a torque, on the other side of the central shaft. This will, of course, impart the desired rotary motion to the central shaft. Offset arms connected to each pivot shaft on a given set of arms and a rod rotatably such offset arms coordinate the movement of vanes on the set of arms to preclude such vanes from becoming entangled with one another.
