We have seen many green projects around these parts and wind up energy products like flashlights are nothing new, but why not wind up batteries to power any gadget?
Designers Yeon Kyeong Hwang & Mieong Ho Kang have come up with this concept design for a battery that can be recharged by twisting the battery itself. By using a built-in spiral spring wrapped around a generator, friction is created which in turn is converted to energy for the built in Ni-mH battery.
While the idea of free energy is great, you would have to twist this thing a whole lot to build up enough juice, not really practical. Maybe if there was a kick-out crank for leverage, but until then I’ll stick with my solar charger.
