We have featured a number of wind-up radios here at Geeky Gadgets before, they are now pretty common, but I think this is probably one of the first MP3 players which is powered using a hand crank.
The Lifeplayer is a portable MP3 player that also features a multi band radio, and it has a built in removable solar cell that can be recharged by the built in solar panel, and it also features a hand crank.
It is designed to be used in the developing world, and it comes with 64GB of educational and informational content pre-loaded, there is also a microSD card slot, and it is currently being tested in Rwanda.
You can find out more details about the Lifeplayer over at Lifeline Energy.
