Here’s a cool lookin’ MP3 you can crank to re-charge the battery.  Crank for about 10 minutes and you get 50 minutes of playing power.  Of course, the MP3 can also be re-charged via USB.   Now, THIS is what iPod  needs, ability to crank it up. Sure, you can sit on the train and twiddle your crank but to save you from such embarrassing moments, this does allow for recharge via USB. It takes approximately 2.5 hours to get a full-charge but if you insist on cranking, it will take about 10 minutes at 2.5 rotations / second to give you the equivalent recharge of 50 minutes via USB. via akiba-gadgets
