First Large-Scale Rooftop Wind Power System-

Green Energy Technologies LLC, a leading supplier of municipal wind energy circuits, announced their most recent proprietary wind technology at the WINDPOWER Conference 2009. The inimitable rooftop wind turbine, called the Wind Cube, is designed specifically for on-site alternative electricity production by power consumers in metropolitan and suburban areas. Measuring a mere 22 x 22 x 12 feet, the commercial wind turbines are intended to fulfill a vast array of consumer’s energy needs; from industrial office buildings, to large-scale retailers, utility customers in isolated areas, and even university campuses. The WindCube unveils ground-breaking automation which utilizes the speed wind tunnel effect, branded in physics as the Bernoulli Principle, to capture and amplify wind power to deliver more kilowatt hours (kWh). It is available as single 60 kW or dual 120 kW systems and tower-mounted or rooftop models. The design works once wind is enveloped inside the WindCube, where the flow grows more intense and initiates amplified speed to yield more green energy. Due to this increased wind stimulation, the WindCube is capable of encapsulating wind energy traveling as slow as 5 mph and while most wind industry engineers produce energy through free-steam wind, this technology generates the same amount of power as a traditional turbine with 50 ft. diameter blades. One WindCube is said to yield about 160,000 kWh annually at an average wind speed of 15 mph. It creates electrical energy by operating its motor backwards using an impeller, which expels the need for a transmission box, significantly lowering the cost of ownership – since most problems arise due to the transmission equipment failures in conventional wind turbines.

In addition to amplified energy production, the WindCube and other small-scale renewable wind power systems provide consumers with the possibility of net metering, a simple and inexpensive method for promoting and rewarding the use of wind renewable energy. It is utilized when a customer generates more electricity than is required for their needs, which causes the existing electricity meter to spin in reverse, assigning a monetary credit to their electric bill every month. The other advantages associated with renewable energy credits (RECs) is involved in President Obama’s American Recovery and Reinvestment Act of 2009, which includes specific conditions granting buyers of small wind systems a federal tax credit of 30 percent of the total installed cost for systems installed and utilized between now and the year 2016. To boot, there are many states throughout the U.S. which provide some form of incentives to make the renewable power switch. The cost is figured to be around $250,000-$300,000 plus the cost of installation, and not to mention, federal and state incentives can reduce the cost by as much as 70 to 80 percent. “Now building owners anywhere can consider being a part of the renewable energy picture,” stated Mark L. Cironi, president and founder of Green Energy Technologies, and with John W. Fedor, WindCube 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 revolutionary design behind the WindCube points to additional advancements in future wind energy science, as well as other forms of renewable sources. The initial outline may lead way to more efficient and cost-saving implementations, which will help change the way some individuals think about environmentally conscious practices – and that is absolutely priceless.
