Funny Looking Tower Generates 600% More Electrical Energy Than Traditional Wind Turbines

Sheerwind INVELOX Wind Turbine

The Sheerwind wind turbine promises to produce 6 times the electrical power than traditional wind turbines.

This funny looking wind tower acts like a funnel, directing the wind from any angle, down through a tube to a ground based turbine generator. The funneling of the wind through a narrow passage effectively creates a “jet effect” increasing the velocity of the wind, while lowering the pressure. This is called the Venturi Effect. This speeds up the wind turbine mounted inside the narrowest portion and generates electricity.

As such it can capture and generate electricity at a much lower wind speed than current wind power technologies.

The idea is so simple, so elegant, and promises to produce so much more energy at lower cost and more efficiently, that it might just be the answer to many problems with current wind turbine technology. Aside from the lower capital investment to get started, and increased efficiency and power generation, it also might be a solution to the ever growing problem of birds (and bats) being killed by traditional wind farms. (Yes, that is a problem)

This technology is not really new in the science of fluid dynamics, however this is a new way to generate electricity, and if successful, promises to grow the wind energy in a more eco-friendly way than ever thought possible.

Imagine a smaller HOME version on your off grid cabin. Now THAT is cool off grid tech!

Sheerwind INVELOX Wind Turbine

Conventional wind turbines use massive turbine generator systems mounted on top of a tower. INVELOX, by contrast, funnels wind energy to ground-based generators. Instead of snatching bits of energy from the wind as it passes through the blades of a rotor, wind is captured with a funnel and directed through a tapering passageway that naturally accelerates its flow. This stream of kinetic energy then drives a generator that is installed safely and economically at ground level. – See more at:

  1. What about the wind released at the base; could that be a problem (especially in the event of high winds) concentrating in one specific direction? Also, what about possibly extending segment #5 up and back in, looping the air back into the intake — could that potentially recuperate some of the energy that would otherwise be lost?

    • I love this idea. Just as a car can recycle air into the engine via a turbocharger or supercharger perhaps some of the exhaust air could be recycle into the Venturi to increase its speed. The ideal solution would be to extract all the speed out of it by converting it to electricity and venting just a gentle breeze. Maybe a heat exchanger could be employed where the tube restricts or expands, too?

      • Sounds excellent to me, Theo, and I’d love to hear from other technically-minded folks who might have more great suggestions. I like what these Sheerwind guys are thinking, so why not make this idea the best it can be? We all stand to benefit from awesome technology.

  2. Needs to be simplified i.e. too expensive to build compared to a normal one. I like that the turbine is at ground level. I think it is a good beta. What else could the exhaust be used for?

  3. Dear offgridworld,
    When I worked for a very large auto company, I designed HVAC duct that turned 90 deg corners with 70% increase in efficentity in air flow based on the fluid dynamics. It was never patented. You have my phone number and my email. I will show you how to double your power.
