"Upside Down" Windmill
“At low wind speeds, conventional windmills run at only about 10 percent capacity while our system reaches 72 percent,” says Daryoush Allaei, CEO and founder of SheerWind in Chaska, Minn.
SheerWind works in urban areas as well as wide open rural areas. Other advantages include no noise from exposed blades, no birds harmed by spinning blades and the ability to create towers out of a variety of materials, because they don’t need to hold up heavy turbine blades.
“You could take existing silos and convert them. Put an air-catching head on top and a generator below, and you’re done,” Allaei says.
The model in Chaska is made of flexible materials, so it’s portable and has the potential to be deployed for military and emergency use.
Allaei envisions different size SheerWind systems for a variety of customers: building owners, communities, industrial parks, shopping malls, mega farms, etc. Currently his company is custom-building systems for clients who have specific kWh energy goals. Eventually he hopes to set up mass production of 4 or 5 models. According to simulations and field-testing, the Invelox technology can produce three times more energy than a traditional wind turbine and bring wind power generation costs down to 1 to 2 cents/kWh. Installation costs are about 40 percent less than traditional turbines and 40 to 50 percent less expensive to operate and maintain.
With recent publicity and energy awards, Allaei says he has been contacted by people and companies in the U.S. and overseas.
