This wind turbine makes use of funnels and tubes to harness wind energy. The Invelox turbine is capable of harnessing wind energy from winds which are as slow as 2mph and that is made possible by directing the wind into a funnel and then channeling it via a tube to the generator of turbine located on ground. Usually the wind turbine generator is situated on top of the tower. However, Invelox keeps the generator on ground and directs wind to it. The other obvious difference being that in conventional methods, wind energy is harnessed when it passes through the blades. With this design, that wind is captured via a funnel that leads to the generator.
So how is it done? Basically, the wind is made to pass through a passage which tapers along the way and hence, accelerates. This induced kinetic energy is then used to run the generator. The effect is known as ‘jet effect’ and is achieved by forcing the wind to blow down a passage which narrows at the end. The end result is wind with increased velocity but low pressure. The technique is known as Venturi Effect and as per Sheerwind, by employing this technique, the wind turbine can operate even when the wind blows at 2mph.
