A combination of new technologies, developed in collaboration with the U.S. Department of Energy’s National Renewable Energy Laboratory, resulted in a product that quietly produces electricity for a fraction of the cost of current technologies. Skystream’s low cost and low profile provides homeowners an affordable energy supplement that’s appropriate for installation in many residential areas around the country. With no batteries, Skystream 3.7 connects directly to the home to supply power. When the wind is not blowing, the home is powered by the electric utility. Depending on the local utility, excess electricity can be sold back to the utility or used at a later date. With a typical cost of US$8,000 to US$10,000 to purchase and install, Skystream 3.7 can pay for itself in 5 to 12 years.
