Some of you were wondering how the homeless charge their cellphones—maybe they do it Chechen-soldier style and create wooden, dynamo-powered cellphone chargers out in the untamed wilderness.
The chargers, developed by Chechen soldiers work by generator turned by crank and pulley. Electricity stores up in the capacitor (the blue thing), which charges the phone. You'd probably have to put in a bit of a workout to see any results, but hey no more flabby arms. [CNET Crave, Photo from English Russia]
