Rethinking Wind Power

The Invelox is an innovative wind energy source, envisioned by Dr. Daryoush Allaei, CEO of the SheerWind company, which may solve the dilemmas faced by traditional wind turbines, including noise nuisance and inconsistent levels of energy output.

The Invelox is funnel-like in both appearance and function. Using the Invelox, outside winds are captured and funneled to create a natural increase in the wind’s speed so it can be converted into energy. Winds as low as 2 mph are captured by intake tunnels and travel through a sharp, 90-degree angle turn.

At this point, the wind reaches speeds of up to 40 mph, while the tunnel gradually narrows, reducing the amount of fluid pressure as the wind travels through a more constricted section of the tunnel. Upon release into the re-expanding tunnel, the wind is sent to ground-based generators or turbines and converted into energy.

Invelox is scalable and can operate on wind farms of a grand scale, as well as micro-generating settings. It takes up to 90 percent less land space than traditional wind turbines as it is 50 percent shorter than the average turbine, with ground-based turbines possessing blades that are 84 percent smaller, making it a low maintenance alternative.

Because its turbines are built within the Invelox unit, it is resistant to outside weather hazards, like freezing or harsh fluctuations in temperature. It is also safe to birds and other animals, and does not interfere with avian migration or military radar systems. This paired with its ability to produce more power at lower wind speeds makes it accessible to wider range of climates than traditional wind turbines.

With product models ranging in power from 5 to 7,000 kw, Invelox units can be used for commercial buildings and as a community wind source, or even serve the military and homeland security. Most product models will be available within this year, with the exception of the Utility Scale Invelox, which will be available sometime in 2014.

The first small scale Invelox unit was installed in Chaska, Minnesota and a larger-scale field unit demo has since been constructed, with data still to be released.

Invelox technology has been reviewed and validated by a technical advisory board, consisting of a team of experts from major research universities and agencies, including professors from the Minnesota Supercomputing Institute and the Center for Advanced Engineering Design and Development.
