Wind-powered Wi-Fi Sensors

Glenn Fleishman writes "According to an article at Indolink a 10-centimeter diameter windmill can produce the 7.5 milliwatts needed for a wireless sensor. The paper was published earlier (available as a PDF), but Nature magazine has apparently picked up the tidbit. The process flexes piezoelectric crystals to create a current. Although flywheels aren't mentioned in this article, it seems like a windmill, a flywheel, and a solar cell could in combination produce effective power in a range of conditions for remote wireless devices, including network relays obviating batteries entirely."

    How about bring them back with a geeky Wi-Fi vengeance?

    Possibly even attach an LED headband to it to tell others how close to a hotspot they're in. C'mon, I see profits galore!
