Abstract:
1. A wind turbine apparatus which comprises: an elongated shaft; a plurality of rotor wheels fixed to said shaft at axially spaced intervals, each rotor wheel including first and second opposed circular walls and a plurality of scoop members carried between said opposed circular walls at angular intervals throughout the circumferential extent of each rotor wheel; a first generally cylindrical housing disposed in concentric relationship with the periphery of said rotor wheels and said elongated shaft, said first generally cylindrical housing having a first axial extremity and a second axial extremity and said first generally cylindrical housing comprising a plurality of passageways, each of said passageways being disposed in registered relationship with one of said rotor wheels; and a second generally cylindrical housing disposed outside of said first generally cylindrical housing as well as disposed in substantially concentric relationship with said shaft and said first generally cylindrical housing, said second generally cylindrical housing having a first axial extremity and a second axial extremity, and said first and second generally cylindrical housings having respective axial portions radially aligned and defining an annular chamber therebetween, said annular chamber having a first axial extremity, proximate to the respective first axial extremities of said first and second generally cylindrical housings, that is open for receiving ambient air flow and a second axial extremity proximate to the respective second axial extremities of said first and second cylindrical housings that is closed, whereby axial airflow into the annular chamber is substantially directed in a radial direction by said passageways, which are respective cup shaped surfaces, toward said scoop members carried on said rotor wheels to cause rotation of said shaft.
