Breath powered charger proves that you're more than just hot air

We've seen all kinds of crazy ways to generate power, but this latest idea proves that your breath isn't just a bunch of hot air. Researchers at the University of Wisconsin-Madison have developed a tiny piezoelectric microbelt that can generate tiny amounts of electricity.

Researchers Xudong Wang, Chengliang Sun and Jian Shi say that the device creates a tiny charge as it vibrates when exposed to moving air, delivering enough power to recharge medical devices such as pacemakers and blood glucose monitors.

They say the device can be implanted in the nose, where it will see constantly moving air as you breathe. I just wonder how you would be able to blow when you were stuffed up, and heaven help you if you're a nose picker.
