OSTI ID:5293422
A wind-powered prime mover comprising a platform, a power shaft rotatably carried by the platform, a horizontal turn table rotatably supported atop the platform, a pair of elongate laterally spaced vertical columns projecting up from the turn table, a pair of elongate vertical rotors about and rotatably carried by the pair of columns and defining a vertically extending forwardly and rearwardly opening wind gate opening therebetween, a transmission means is engaged with and between the rotors and shaft and causes counter rotation of the rotors and rotation of the shaft when the rotors are drivingly turned, the rotors include a plurality of circumferentially spaced longitudinally extending radially outwardly projecting vanes which are positioned so that the vanes of each rotor occur between adjacent pairs of vanes of the other rotor when the rotors turn and the vanes advance rearwardly through the wind gate opening, the vanes have curved trailing reactive surfaces curved radially outwardly and circumferentially in the direction of rotation of the rotors and disposed forwardly, laterally, inwardly and rearwardly as they advance laterally inwardly, rearwardly and laterally outward relative to the wind gate opening; and air flow control means comprising a pair of laterally spaced shrouds positioned about the outer portions of the pair of rotors, the shrouds have laterally inwardly opening recesses freely rotatably accommodating the outer portions of the rotors and vanes and have vertical forward edges that define the front of the wind gate opening, the pairs of shrouds have wind directing surfaces projecting forwardly and outward from the edges and which direct air laterally inwardly and rearwardly to the wind gate opening.
