Abstract

A wind-powered turbine has a housing with an inlet and an outlet. Located in the housing is a cylindrical stator array having a plurality of spaced-apart stators located in it. An annular cylindrical rotor array having a plurality of cups rotates about a central axis, fits inside of the stator array. The stators are positioned to cause air which flows around the outer periphery of the stator array to impinge on the rotors and an air handling system causes air entering the housing to be distributed substantially around the periphery of the stator array.
