Green Energy Technologies Launches WindCube(R) at Windpower 2009

First Commercial-Scale Urban Wind Power System for Rooftop Use. Customers With Small Footprints, Moderate Wind Can Expect Short Payback.

Green Energy Technologies LLC, a privately held company founded in 2006, announces the launch of WindCube(R), a 60kW rooftop wind turbine designed for on-site power generation by commercial and industrial power users in urban and suburban locations. The turbine, which captures and amplifies the wind, fills a previously unmet need for wind turbines that can be placed into service in a very small footprint and take advantage of the nation’s net metering laws.

“Now building owners anywhere can consider being a part of the renewable energy picture,” said Mark L. Cironi, president and founder of Green Energy Technologies, and with John W. Fedor, the technology’s inventor. “With WindCube, it’s not necessary to have the wind of Kansas or Nebraska to become a generator of wind power. In states with excellent renewable energy incentives, moderate wind and high electric rates, the payback can be as little as three years.”

The turbine is available as a single (60kW) or dual (120kW) system and in rooftop or tower-mounted design. The product is modular to satisfy a customer’s electrical requirements, and produces the same amount of energy in a 22×22x12-foot framework as a traditional turbine with blades 50 feet in diameter. It is ideal for a wide range of users, from industrial companies and commercial office buildings to big-box retailers, college campuses and electric users in remote locations.

Innovative Technology Amplifies Moderate Wind
The WindCube features a groundbreaking patent-pending design that relies on the wind tunnel effect known in physics as the Bernoulli Principle. While the rest of the wind industry generates energy through the use of free-stream wind, the WindCube captures and amplifies the wind, which produces more kilowatt-hours (kWh). As the wind comes into the WindCube shroud, it becomes concentrated, creating increased velocity and in turn, more power. Because of the amplification effect, the WindCube is able to capture wind energy as low as 5 mph.

The WindCube generates electricity by running its motor backwards using an impeller (the opposite of a propeller), eliminating the need for a gearbox. This lowers the cost of ownership because the gear box is the source of most of the maintenance problems and failures on conventional wind turbines.
