Funnel based wind turbine claims big gains [View all]
....One company out of Minnesota claims to have a new wind power generation technology that can alleviate most of the world’s concerns. SheerWind says its Invelox system can operate in a wider variety of conditions and is up to 600% more efficient than traditional wind turbines.
Those large wind turbines you’re used to see dotting the skyline in rural areas rely on fairly swift winds to function. Invelox can generate power from winds as gentle as 1-2 MPH. It does this by capturing passing breezes in large scoops at the top of its 40-50 foot tower. The wind is funneled down toward the ground through an increasingly narrow space. When the air is compressed, it speeds up and is used to power a small turbine generator.
