SheerWind Inc. of Chaska, Minnesota is claiming in a press release that its newly developed funnel-based wind turbine system is capable of producing 600 percent more power than conventional wind turbines. The new design uses funnels to channel wind to a ground-based turbine.

The idea behind the INVELOX system is to capture wind using wide mouthed funnels and channel it via ducts to a turbine sitting at ground level. The wind picks up speed as it is concentrated through a series of nozzle and pipes before it is delivered to a turbine, which produces electricity. SheerWind claims in its announcement that the system is capable of producing electricity with wind speeds as low as 1mph.

As an example, they say that tests have demonstrated that the system operating in natural wind speeds of 10mph is able to increase that speed to 40mph before it enters the turbine. After passing through the turbine, the wind is exhausted back into the environment, in this case, at 15mph.

In another scenario the company says it tested the abilities of its system by comparing it with an identical turbine configured as a conventional system. They claim they found improvements of 81 to 660 percent.

The company says the […]
