I also designed a Vertical Axis Savonius Rotor for battery charging. It uses a 30 degrees wind concentrator over and below the rotor. The author conducted wind tunnel tests on models simulating dams and found a 30 degrees slope increases wind speed by 1.5 times. Since power is cube of velocity,the power gain is 3.34 times. This has its origin from nature in that how is it we experience high winds on a hill top and dams? It is due to height and due to slope. This Savonius Wind Rotor will be a boon in rural areas.

The vertical wind turbines are really a great approach for roofs of flat city buildings. The noise won´t be a problem at all on higher buildings I lkie the idea with the combination of wind and solar.

Incl mine (rejected in 1992). There is so much potential to farms of these over the classic horizontal design. These and solar are the wave of the future. Click through http://muthaofinvention.blogspot.com/2008/04/my-windmill.html and to see more videos of the butler design.

The copy-cats are 50% more expensive and produce less power. GUS Vertical Wind Turbines...100% bird and bat safe!! Nothing else comes close! go to: www.wildnaturesolutions.com/windturbines Check these VAWT’s out..these GUS turbines are the state of the art,
