A wind turbine apparatus includes a shaft carrying a plurality of rotor wheels fixed at axially spaced intervals. Each rotor wheel includes buckets at the periphery thereof. First and second generally cylindrical housing are disposed in concentric relationship to define a blind annular chamber surrounding the rotor wheels that directs ambient winds to through the inner wall of the inner cylindrical housing to the periphery of the respective rotor wheels. One extremity of the blind annular chamber is open for receiving ambient air flow and a second axial extremity proximate is closed, whereby axial airflow into the annular chamber is substantially directed in a radial direction by the toward the buckets carried on the rotor wheels to cause rotation of the shaft.
