Title:
THE SUNDERLAND VAWT
Document Type and Number:
WIPO Patent Application WO/2012/137028
Kind Code:
A2
Abstract:
A multi generator VAWT. The main purpose of this invention is to supply cheaper wind powered electricity from a safe, simple and versatile device. I will attempt to describe the VAWT with reference to the accompanying drawings. The generators should be secured equidistance around the outer periphery as in drawing 1 of 5 marked bottom. The turbine, as in drawing 2 marked central fan, should be placed on top of generators. Most drag type turbines could be used in this VAWT. The main body, as in drawing 3 marked outer ring, should be placed over the turbine and generators. The drawing 4 shows the VAWT assembled with doors open. The drawing marked 5 shows doors closed. For extra safety, mesh should be fitted across the wind access/exit ports (not shown).

Claims

1. A safer, less expensive VAWT that can be sited closer to where the electricity is required.

2. Easier to shut down to maintain the most vulnerable part of the VAWT, the

generators.

3. Very safe; all moving parts are within fixed housing.

4. A larger outer diameter gives balance and stability, and also is used to convert low speed to high speed.

5. Fixed original five sided shape that always has more than one wind access aperture open no matter the wind direction.

6. Deflectors to convert negative wind (drag) to positive wind.
