Mini windmills for powering very small devices


There are many applications for remote sensors and other small electronic devices in remote locations without access to the electrical grid, and where batteries may be unsuitable. A group from the University of Texas, Arlington has built a miniature windmill is 10cm (a little less than 4 inches) in diameter and can provide a power output of 7.5 milliwatts in a breeze of 16 km/hour (10 mph).

The novel aspect of this design is in its use of piezoelectric crystals rather than a conventional generator. Piezo crystals generate a voltage when they are deformed, and are commonly found in cigarette lighters and barbeque ignitions. This piezoelectric windmill brushes a series of cymbal-shaped transducers as it rotates to generate electricity.

A conventional generator that used a 10-centimetre turbine would convert only 1% of the available wind energy directly into electricity. A piezoelectric generator ups that to 18%, which is comparable to the average efficiency of the best large-scale windmills, says Priya.
