The Twirling Battery

If everyone had batteries like this, then no one would need to bring chargers ANYWHERE. This battery, designed by Yanko Design has it's own recharging feature. As you can tell from the picture, all you have to do is twirl the thing around your finger. While the designers say the battery isn't meant to be 'eco-friendly' or a 'green' concept, you have to see how this could segue into a whole new sector of power. Too bad they only make it in Japan and for that specific phone. Check out some specs and the quickie tutorial...
