simply put it is a ultralight (1 ounce) generator in a blow tube. as we work or type or whatever it is we do when working, our breathing which is unused energy spins a tiny turbine with a small but usable charge, enough to keep a battery pack charged which itself has 2 usb ports for hooking up mp3 players, phones, etc, anything that can run on usb
