Sheerwind: Wind Harvesters for Electrical Production

On the Sheerwind website, an interesting approach to capturing wind, concentrating it through a funnel and using the pressure to turn a turbine. Among the many advantages, cheaper to build and maintain and works with less than 2mph wind speeds.

SheerWind’s INVELOX technology captures, accelerates, concentrates, and generates electrical power when wind is at its optimum state of energy. INVELOX replaces traditional wind turbines that use a massive turbine generator systems on top of a tower. Instead of snatching bits of energy from the wind as it passes through the blades of a rotor, the wind is captured with a funnel and directed through a tapering passageway that accelerates its flow. This stream of kinetic energy then drives a generator that is installed safely and economically at ground level. The concentrated wind flow power output rises almost exponentially. Bringing the air-flow from the top of the tower to ground level allows us to generate more power with much smaller turbine blades. The tower is about 50% shorter than traditional wind towers, and uses a groundbased turbine with blades 84% as long.
