SheerWind is claiming several advantages from the INVELOX. By increasing the speed of the wind hitting the turbine blades, SheerWind says they can boost power output by almost 3 times. The INVELOX can also produce power at lower wind speeds than conventional horizontal or vertical wind turbines.
SheerWind also thinks that their design will be cheaper to install, since a significant challenge for conventional wind turbines is the difficulty in transporting and mounting their gigantic turbine blades. Because the INVOLEX funnels the wind down to a ground based small turbine, they can use much smaller blades than conventional wind turbines. Sheerwind also claims lower maintenance costs since its cheaper to maintain a ground based turbine than a turbine nacelle that’s hundreds of feet up in the air.
The company recently completed and installed its first large scale prototype. Initial testing (without the turbine in place) shows that they’re getting increased wind speed passing through the INVOLEX – almost double the speed of the outside wind. They’re now in the process of installing the turbine and producing electricity.vawt, Involex, vertical wind turbine, wind turbine design, Sheerwind, ducted wind turbine
