How INVELOX™ Works 

  1. Wind is captured at the top of the funnel shaped INVELOX system. The omnidirectional intake area allows wind collection from any direction

  2. Wind is funneled through the system

  3. Wind is concentrated and further accelerated in the Venturi Effect* section of the INVELOX system. *The Venturi effect is the phenomenon that occurs when a fluid that is flowing through a pipe is forced through a narrow section, resulting in a pressure decrease and a velocity increase.

  4. Wind is delivered to the turbine/generators to convert the accelerated wind to electrical power. INVELOX is the first single wind tower capable of powering multiple turbines in a row or series

  5. Diffuser returns wind to nature

This system of capturing, concentrating, accelerating, and harvesting wind power in a funnel is a patented system we call INVELOX™ (for INcreased VELocity). SheerWind is a wind power generation company that is poised to turn wind power into a major power generation player. SheerWind’s INVELOX is a solution that utilizes current wind power turbines and rotors but brings them to ground level for easier, safer, and cheaper operation and maintenance. Multiple turbines can be used in a row or series increasing output exponentially for each tower.

SheerWind’s mission is to provide sustainable, affordable, electrical energy to anyone, anywhere.

INVELOX is scalable, equally suitable for use in major wind farms or micro-generation settings. It will produce power effectively at much lower wind speeds than current systems do, which means it has a dramatically wider geographical range.

Technology Validation

INVELOX technology has been reviewed and validated by a technical advisory board, a team of experts from major research universities and agencies. Prototypes were tested under controlled laboratory conditions, and test results were used to build and validate full-scale computational fluid dynamic (CFD) models.

Several demonstration units have been tested since construction in 2012. The first small-scale unit was installed in a field near SheerWind’s facility in Chaska, Minnesota. The unit incorporates the instruments for full speed and power data collection. Speed data has validated CFD model predictions.

A large-scale (commercial-grade) field demo unit has been tested for over two years. Data collection and testing has continued to exceed expectations.


Comparing INVELOX commercial-grade wind energy generation with the same turbine on a traditional tower-mounted system. The test results indicate that INVELOX significantly out-performs the traditional turbine and is competitive with natural gas and hydroelectric generation by:

  • Producing 600% more electrical energy (kWh)
  • Operating at wind speeds as low as 1 mile per hour and in low wind regimes (class 1 and 2)
  • Reducing installation capital cost to less that $750 per KW
  • Increasing energy production capacity to record high of 72%
