A power conversion turbine for actuation by fluid in motion such as, for example the wind, with a body supported to rotate about a central axis and carrying a plurality of vanes spaced from said axis and being movable about respective vane axes parallel to said central axis and which vanes are circumferentially spaced from each other and dimensioned such that, when said vanes are in a FIRST closed position they collectively form a substantially unbroken cylindrical surface and are selectively movable from said FIRST position to a fully open SECOND position and said vanes including interconnecting means causing selected ones of said vanes to close as one or more opposing vanes are caused to move from the first to the second position by reason of passage of fluid and means integrally connected with said interconnecting means for infinitely varying the degree of opening of the vanes between fully closed and fully open positions. An auxiliary strip may be provided along the full length of the inner surface of each vane near the leading edge to facilitate and accelerate the initial opening movement of the vanes.

A turbine or the like comprising: a support; a body fixed on said support for rotation about a central axis; a plurality of vanes pivotally mounted on said body along respective vane axes peripheraly spaced from said central axis and equally spaced from each other; each said vane being movable on its respective axis to and from a FIRST or closed position and a SECOND or fully open position; said vanes being contoured and dimensioned such that, when said vanes are all in said FIRST position they collectively present an outer surface in the form of a cylinder; cable means interconnecting each said vane with at leat one other, opposing vane, operative by reason of said one vane opening, to cause one or more opposing vanes to close; and means cooperatively connected with said vanes and said interconnecting means for selectively, manually changing the effective length of the cables between each pair of vanes causing all of said vanes to be simultaneously closed or the amount of opening to be diminished while said body is rotating or at rest.
