A vertical axis wind powered generator comprising: a stationary mainshaft support means; a rotor rotatably mounted on and supported by a said stationary mainshaft; a wind energy conversion means; said rotor equipped with a multitude of airfoil shaped vanes, each said vane attached to its vane shaft and each said vane shaft rotatably mounted on a top circle of rotation at the top of said rotor and each said vane shaft rotatably mounted on a bottom circle of rotation at the bottom of said rotor, such that said circles of rotation have equal diameters and such that said circles of rotation are concentric with each other and with said vertical axis, and such that the top ends of said vane shafts are rotatably supported and equally spaced from each other by a pervious top support plate, and such that the bottom said ends of said vane shafts are rotatably supported and equally spaced from each other by a pervious bottom support plate, and such that aerodynamic forces developed by said airfoil shaped vanes are transferred to said support plates as rotary forces, and thus to said rotor as rotary forces; a synchronous vane orientation means; a normally stationary but incrementally adjustable orientation toothed-wheel mounted concentrically with and attached to a normally stationary but incrementally adjustable orientation spindle, and having exactly one half the pitch diameter of each wane toothed-wheel; a multitude of identical said vane toothed-wheels equal to the quantity of said multitude of airfoil shaped vanes such that one said vane toothed-wheel is mounted on and attached to one said vane shaft such that rotation of said vane toothed-wheel will cause rotation of said vane shaft which in turn will cause rotation of said airfoil shaped vane and such that each said vane toothed-wheel will mesh with a positive rotation coupling device which has any suitable pitch diameter, or pitch length, which will mesh with said multitude of identical said vane toothed-wheels and simultaneously mesh with said orientation toothed-wheel; a said rotor constructed such that said bottom support plate also provides support and alignment means for said quantity of said positive rotation coupling devices in such a manner that said quantity of said positive rotation coupling devices will cause all said multitude of said vane toothed-wheels to rotate simultaneously when said quantity of said positive rotation coupling devices is caused to rotate simultaneously by said orientation toothed-wheel; a said orientation spindle mounted concentrically with said mainshaft in a manner in which the angular position of said orientation spindle may be held stationary, or may be incrementally adjusted, by means located externally to said wind generator\s said rotor, regardless of whether said rotor is stationary or rotating; and whereby holding said orientation spindle stationary while said rotor is rotating provides a said synchronous vane orientation means whereby the orientations of all said multitude of airfoil shaped vanes with respect to the wind is synchronized with the rotation of said rotor, and whereby angular incremental adjustment of the position of said orientation spindle provides a means for incremental and simultaneous adjustment of the orientations of all said vanes with respect to the wind so as to control the aerodynamic forces developed by said airfoil shaped vanes and thus control the rotary forces, rotary speed and power output of said rotor, or so as to cause said rotor to rotate in either direction of rotation; an orientation spindle adjustment means; an orientation servo-mechanism, located externally to said wind powered generator\s said rotor, and said servo-mechanism equipped with an output shaft which is rotationally coupled to said orientation spindle such that adjusting, either manually or electrically, said orientation servo-mechanism\s said output shaft in angular increments provides a means for adjusting said orientation spindle in angular increments with respect to the said wind so as to externally control the said synchronized orientations of the said airfoil shaped vanes with respect to the wind and thus externally control the said aerodynamic forces developed by said airfoil shaped vanes; a power output means; means for transferring the said rotary forces and said power output of said rotor from said rotor to the shaft of a driven machine, such as an electrical A.C. or D.C. generator.
