Kinetic energy mobile phone

The Atlas Kinetic cell phone is a concept which looks to eradicate the need for re-charging by having a power source generated by movement, similar to some watches. It works by means of an oscillating weight that powers a mainspring and "if power runs out because it was sitting still for too long, just give it a few upside down turns to get the kinetic rotors going again."
As a result, you'll never have to worry about batteries or battery life again if you were to own this striking mobile. Unfortunately, it's just a designers idea at this point, so there's no saying when and if it'll ever make it to production.
