    Miniture windmills could power outlying wireless networks

    What better way to power WiFi in the back of beyond than with little windmills?
    Dr. Shashank Priya thinks he has the solution to this problem, in the form of miniature windmills that can provide adequate power from breezes as faint as 10 MPH. Priya’s 4-inch diameter ‘mills differ from their larger counterparts in that they employ piezoelectric crystals which generate a current when flexed by a rotating cam. Were he to have used the conventional generators found in regular windmills, his minimills would only achieve one percent efficiency, as opposed to the 18 percent they can reach using the piezoelectric materials.

    Remember that kids, it's all about piezoelectric materials!

    Arean't piezoelectric materials some sort of holly grail, or something? Are they the things that are supposed to give us wall warts the size of regular plugs without the heat and lack of efficiency?

    Instead of windmills you could use solar panels too i guess. Iæve seen them up in Shetland on top of bus stops in the middle of no-where to power the light
