Abstract

A wind tower harvests wind energy to produce electricity using four major components: (a) a tower, (b) a windcatcher at the top of the tower, (c) one or more diffusers, and (d) one or more wind generators. An inlet with four quadrant peaks, mounted at the top of the wind tower, is shaped to capture an increased volume of air flow and divert this air flow down into the channel or well of the wind tower, thus increasing output of the generator. A shaped diffuser directs the downward air flow in the well onto blades on one side of a drum turbine's axis of rotation, thus rotating the turbine. Rotation of the turbine rotates a generator attached to the turbine to generate power.
