Breathing generator

 Make power even in your sleep

Breathing is a motion that never stops for long - unless you are dead of course. Put an elastic belt around your chest that has built in Piezo elements or some other generator in a suitable configuration and you make power from breathing, even in your sleep. It won't be a lot of power since you don't want nightmares about being strangled by a python, but it could probably keep a cell phone charged or run a heartbeat monitor, or other useful widgets. The device could also help to burn extra calories for those who need it.

       So your phone will always be fully charged, but you'll feel like you've got asthma?

       I wonder whether this would lead to the development of more powerful muscles - possibly around the diaphragm.

       [pert] - I see, yes, this could be part of a training regime, like how elite cyclists train at altitude to force their cardiovascular systems to become more efficient

       An electrical muscle stimulator would be better and safer for burning calories.

       Hook up an electrical muscle stimulator to a muscle-powered generator.
