Reply to comment by FartingBob in Scientists have developed a low-cost small device (15x20cm) that can harness energy from wind as gentle as a light breeze and store it as electricity. With wind at 2 m/s the device can produce 3 volts and generate power of up to 290 microwatts (sufficient to power a commercial sensor) by giuliomagnifico

As the article says, it would be ideal for using instead of a battery, to avoid having to replace the battery. I'm assuming this doesn't scale up. If it's so responsive it can't be very hardy.
