Using some parts scavenged from an old CD-ROM drive, some dude at instructables has built a breath-powered USB charger. While he says that it's possible to get 1 W out of the device, he's only seeing 50 mW. Not so great, as it'd take about 24 hours of breathing to charge your cell phone. But let's be frank...you were planning on breathing anyway. More at Instructables

Smart Clothing

There's talk about smart clothing, you know the kind that has built in sensors or heating elements or stuff like that. Perhaps this would have an application there.
Wow.

If you were to go running and say, breathe faster than normal, would it charge quicker?
WOW me too.

Or if you play a wind instrument? Or Swimming? Which begs the question, is it water-proof?

Science, technology gadgets and...baby seals. We're in a bit of an eco-mess, but we've got the brains to lick any problem. And that's why EcoGeek.org publishes up to ten stories daily about innovations that are saving the planet.
And if that sounds interesting to you, then congratulations, you're an EcoGeek.
A USB socket gives at least 500 mA * 5V = 2.5 Watts, and some dedicated chargers do more. Besides, if you want muscle power, why not use the arms? Although this could be useful for novelty applications (breath-powered flashlight?).
