Superpowerful small wind turbines light up the night


Filed under:

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 headlights "like flashbulbs." That's pretty impressive -- especially since the system is light and balanced enough to be held up with one hand. No word on when or how we might see these hit the public, but we can see some pretty sweet applications -- laptops in the park, anyone?
