We've seem some impressive wind power tech, but a new breed of small, high-power wind turbines could potentially bring efficient wind power home. Developed by an inventor named Doug Selsam, the new turbines have rotors just 14-18 inches in diameter, but can produce 200 watts in a 20MPH wind, and much more than that at higher wind speeds. The trick is using high-strength carbon-fiber materials that allow several rotors to be hooked up as one -- in strong winds a thirteen-rotor system can produce enough juice to blow out a bank of car batteries "like flashblulbs." That's pretty impressive -- especially since t
