Patent ID: 7220096

Claim:
A wind energy extraction apparatus for interacting with a flow of wind, said apparatus comprising concentrator wings defining a capture area bounded by the concentrator wings, the concentrator wings reacting with the flow of wind between the concentrator wings to induce a drop in static air pressure that is then used to drive a plurality of impellors; a power converter associated with each impellor; a flow regulator having aerodynamic surfaces directing the flow of wind impinging upon said flow regulator outwards from said flow regulator and towards the flow of wind reacting with said concentrator wings; and a riser having a first portion supporting said concentrator wings, said impellors and said flow regulator, wherein at least a portion of the flow regulator is positioned within said capture area and said first portion of said riser is positioned relative to said at least a portion of said flow regulator such that said at least a portion of said flow regulator reduces the wind striking said first portion of said riser.
