Southwest Windpower has released its much-anticipated Skystream 3.7 small wind turbine system, which has been designed as a grid-tie turbine with all necessary power electronics integrated into the system. 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," according to a company press release. "With a typical cost of $8,000 to $10,000 to purchase and install, Skystream 3.7 can pay for itself in 5 to 12 years. This payback period will vary and can be much quicker in states with investment rebates. It's anticipated that Skystream 3.7 will save the average homeowner $500 to $800 per year, based on 4,800 to 6,600 kWh produced per year and a $.12/kWh cost of electricity. :: Via: Clean Break and Red Herring
