Superpowerful small wind turbines light up the night
Filed under: Misc. Gadgets
We’ve seem some impressive wind potential tech, but a new breed of small, high-power wind turbines could potentially bring efficient wind capability 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
sufficient juice to blow out a bank of car headlights “like flashblulbs.” That’s pretty impressive — particularly since the system is light and balanced suitable 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?[Thanks, Yocheved]
