Wireless technology has made small remotely-placed electronics more practical, but there was always a problem of how to power the electronics.
An inventor has found a way to make small windmills practical by using piezoelectric crystals. The crystals, when bent, produce a small electric current with more than enough power for a small device.
The breeze moves the fan which, in turn, compresses the crystals which, under pressure, release an electric current, then the power can be used for whatever.
