How Green Energy Technologies’ newly-launched WindCube rooftop wind turbine works

Technologies

Green Energy Technologies unveiled its rooftop or tower-mounted WindCube wind turbine at the Windpower 2009 Conference & Exhibition that took place in Chicago on May 4-7.

The WindCube is designed for high-electricity commercial and industrial users. WindCube comes in 60-kilowatt (kW) or 120-kW dual system. It can generate the same amount of energy as a 50-foot diameter wind turbine, but using only a 22x22x12 foot framework. The wind turbine is designed to operate in moderate wind conditions.

The WindCube uses a wind tunnel effect known as the Bernouli Principle. Unlike large wind turbines that capture free-stream wind, the WindCube captures and amplifies wind to generate more electricity from wind energy. The amplifying effect also allows the
WindCube to effectively capture and utilize wind energy moving as low as five miles per hour (mph). At an average wind speed of 15 mph, one 60-kW WindCube can generate about 160-kilowatt-hours (kWh) of electricity a year.

The WindCube generates electricity by running its motor backwards using an impeller (the opposite of a propeller). This completely eliminates the need for a gearbox, thereby making the system itself more durable and requiring less maintenance. The gearbox requires the most maintenance and is responsible for most operational failures in larger wind turbines.

The American Recovery and Reinvestment Act of 2009 contains a provision that allows buyers of small wind systems (up to 100 kW) an uncapped investment tax credit of 30% of the total cost of the system. The tax credit is applicable to systems placed in service between now and 2016. The American Wind Energy Association (AWEA) predicts that this federal subsidy could help the small-turbine market grow by 40%-50% annually, which would put it on par with the US growth rate of the solar PV industry that was spurred by a similar incentive in 2005.

Each sale of the WindCube system within the US will also be provided with installation and an online remote monitoring service by Roth Bros., Inc. The monitoring system will give customers 24/7 visibility of energy usage. Roth Bros. will also provide post-installation preventive maintenance and service on the units.

Green Energy Technologies is a privately-held company founded in 2005. The company’s featured product is the WindCube. The company is based in Akron, Ohio, USA.
