We've seen plenty spinning, twirling, and wind-up gadgets from Sony and others, but nothing quite like this battery concept designed by Song Teaho and Hyejin Lee. While there's still a bit of work to be done with the actual "working" part, the concept is to simply let you twirl your cellphone battery around your finger a few times for a quick bit of juice to send a text or make a call -- the designers estimate 130 twirls will give you two minutes of talking time. Of course, the same idea could also be applied to batteries for other devices, although you'd probably have your work cut out for you trying to charge your laptop battery.
