Kilian’s Hardware drew many onlookers when it displayed a  large wind turbine of about 7 feet in diameter outside the store. Kilian's Russ Goudy Jr. estimates the turbine might save a homeowner $100 a month in electricity bills, depending of course, on the wind, which needn’t be more than 2 miles per hour from any direction to generate current. The item retails for $7900 and, if this one doesn’t sell, Goudy may mount it on the store’s roof. Watch video interview here.
