600% Energy From Sheerwind's Invelox

The costs of producing wind energy with Invelox are lower, delivering electricity with prices that can compete with natural gas and hydropower.  it captures wind at any speed, even a breeze, from a portal located above ground. The wind captured is then funneled through a duct where it will pick up speed. The resulting kinetic energy will drive the generator on the ground level. By bringing the airflow from the top of the tower, it’s possible to generate more power with smaller turbine blades, SheerWind says.  Besides power performance and the fact it can operate at wind speeds as low as 1 mph, SheerWind says Invelox costs less than US$750 per kilowatt to install. It is also claimed that operating costs are significantly reduced compared to traditional turbine technology. Due to its reduced size, the system is supposedly safer for birds and other wildlife, concerns that also informed the designers of the Ewicon bladeless turbine. Finally, the system also makes it possible for multiple towers to network, that is, to get power from the same generator.
