Abstract
Abstract A system for conversion of wind power to electrical energy. The system provides for use during a wide range of wind velocities by use of the following: an external deflection system consisting of baffles and peripheral turbulence creating walls designed to increase the wind velocity and to divert the wind stream to the aperture of the system; a chamber for the collection and compression of the wind thereby further increasing the wind velocity if necessary; a deflection system for diverting wind from the chamber in high winds; a rigid circumferential tip face at the fan circumference whereby the fan blades fit into the tip race for support; a center deflector to divert the wind force to the fan blade tips; a tip-mounted generating system utilizing induction fields to obtain electrical energy and a system to vary the strength of the induction field so a constant blade speed may be obtained over a range of wind speeds and conditions.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
113 words
A wind driven energy system comprising: a wind chamber; two apertures, one on each side of said wind chamber to permit flow there-through; two fan-shaped windwheels placed within said wind chamber; a venturi-shaped chamber placed within said wind chamber and opening on said apertures wherein said venturi shaped chamber expands in diameter after said first fan-shaped windwheel to a larger diameter when it meets said second fan-shaped windwheel; a conical deflector which progressively widens as it approaches said first fan-shaped windwheel whereupon it decreases in diameter until it meets the second fan-shaped windwheel; a series of baffles exterior to said wind chamber; and a means of producing electrical energy from said fan-shaped windwheels.
Claim 2
Dependent Claim
113 words
A wind driven energy system comprising: a wind chamber; two apertures, one on each side of said wind chamber to permit flow there-through; two fan-shaped windwheels placed within said wind chamber; a venturi-shaped chamber placed within said wind chamber and opening on said apertures wherein said venturi shaped chamber expands in diameter after said first fan-shaped windwheel to a larger diameter when it meets said second fan-shaped windwheel; a conical deflector which progressively widens as it approaches said first fan-shaped windwheel whereupon it decreases in diameter until it meets the second fan-shaped windwheel; a series of baffles exterior to said wind chamber; and a means of producing electrical energy from said fan-shaped windwheels.
Claim 3
Dependent Claim
101 words
A wind driven energy system comprising: a wind chamber; two apertures, one on each side of said wind chamber to permit flow there-through; a hub placed within said wind chamber; a series of blades which are notched at their outer tips, said blades attached to said hub; two channels formed in a surface portion of said wind chamber which interface with said notched fan blades; a venturi-shaped chamber placed within said wind chamber which circumferences said channels and opens on said apertures; a series of baffles exterior to said wind chamber; and a means for producing electrical energy from said blades.
Claim 4
Dependent Claim
101 words
A wind driven energy system comprising: a wind chamber; two apertures, one on each side of said wind chamber to permit flow there-through; a hub placed within said wind chamber; a series of blades which are notched at their outer tips, said blades attached to said hub; two channels formed in a surface portion of said wind chamber which interface with said notched fan blades; a venturi-shaped chamber placed within said wind chamber which circumferences said channels and opens on said apertures; a series of baffles exterior to said wind chamber; and a means for producing electrical energy from said blades.
Claim 5
Dependent Claim
21 words
The wind driven energy system of claim 2 further comprising: rollers located in said channels which interface said notched fan blades.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
77 words
A wind concentrating system exterior to a wind chamber comprising a wind chamber, a fan-shaped windwheel within said chamber, a means for producing electrical energy from said fan-shaped windwheel, a series of baffles positioned to concentrate the incoming wind at the wind chamber, said baffles having upper and lower arms, said lower arm protruding from the side of said baffles at a greater angle than said upper arm affixed to the top of each of said baffles.
