There is provided a method and device for converting energy from a moving gas stream with improved efficiency. One embodiment of the apparatus includes a frame mounted on a rotatable shaft. The frame has working blades and discharge blades mounted thereon, the arrangement of the discharge blades being sufficient to materially reduce any back pressure on the working blades. Flow control means are operatively connected to the frame for substantially normalizing the flow of the moving gas stream as at impinges on the working and discharge blades. There is also provided a method of converting a portion of the energy of a moving gas stream to mechanical energy including the steps of arranging a series of working blades on a frame such that a moving gas impinging on the working blades will rotate the frame; arranging a plurality of discharge blades on the frame to materially reduce any back pressure on the working blades when the working blades are exposed to the moving gas and directing the moving gas in a substantially normalized flow pattern to the working and secondary blades.

An apparatus for converting energy from a moving gas stream comprising: a rotatable frame mounted on a rotatable shaft and having a plenum with an inlet and an outlet, said frame being fixed in relation to the rotatable shaft to thereby rotate the shaft upon movement of the frame; a series of working blades mounted across the plenum in close proximity to the plenum inlet; a series of discharge blades mounted across the plenum at a location sufficiently downstream of the working blades such that the arrangement of the discharge blades materially reduces any back pressure on the working blades; and flow control means fixed in relation to the frame and the moving gas stream, said flow control means being operatively connected to the frame for guiding the flow of the moving gas stream into the plenum inlet in a direction generally normal to the working blades without substantially diverting the general flow of the moving gas stream prior to impingement of the moving gas stream on the working blades.
