If you’ve been practising Qi Gong for quite some time, then surely your breathing is strong enough, even to generate some electricity. Those folks at MAKE who have got pretty good knowledge of D.I.Y, have made a USB AA-batteries-powered charger, but it’s got little more speciaty in it than the one we’ve just seen. It takes rechargeable AA batteries that can be recharged by having you to breath in turns. Furthermore, it’s USB charger, which suits more gadgets. Basically, it consists of some kind of simple electornic circuit, a few rubber bands to make up a generator, so when you’re huffing and pufffing along your way, then the charger’s batteries will pick up charge, which then can charge your gadgets. Currently, this device can produce around 50mW of power, of course, it’s simply too low, which might take almost a day to fully charge your gadgets. For the Qi Gong experts, you’d probably be able to produce much more than that, perhaps only a few hours.
