This concept for a breath-powered iPod/iPhone charger has to be seen to be believed!
"The AIRE mask is a concept that hails from the mind of Joao Paulo Lammoglia, where it will rely on the power of your breath, converting it to electricity thanks to tiny wind turbines. All you need to do is ensure the AIRE mask remains connected to an iOS-powered device, breathe as usual, and you are good to go."
Sure, today you're just charging your iPod. But soon you'll be adding other gadgets, a cape, and servo-arms. Then? Well you might as well go all out and replace a limb or two.
It's a slippery slope I say! ;)
