Abstract
A wind turbine system utilizes an air deflector configured inside of an air scoop extending along a circular track around the air deflector to capture the prevailing wind and direct it up through an air rotor. The air rotor is configured with a plurality of fins in the air rotor channel and the flow of air past the fins spins the air rotor. A rotor of an electrical generator is coupled with the air rotor and spins with respect to a stator, fixed to the wind turbine frame, to produce electricity. The air scoop rotates about the wind turbine as a function of the prevailing wind and may be controlled by a controller that is coupled with one or more of the wheels of the air scoop. A plurality of baffles may be configured under the fins to direct the air and over the fins.
