SheerWind, a wind power company from Minnesota, USA, has announced the results of tests it has carried out with its new Invelox wind power generation technology. The company says that during tests its turbine could generate six times more energy than the amount produced by traditional turbines mounted on towers. Besides, the costs of producing wind energy with Invelox are lower, delivering electricity with prices that can compete with natural gas and hydropower.
Invelox takes a novel approach to wind power generation as it doesn’t rely on high wind speeds. Instead, 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.
