ABSTRACT:
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.
