Gadget supply from Cambridge

My colleague Andreas sent me this cool gadget:

It’s called “RotaryCharger” and charges the mobile phone without any power source. There are several cables suitable for different mobile phones (Nokia, Motorola, Siemens, Ericsson). All you need to do is twist the handle and rotate it clockwise. Three minutes charging will give approx. 2-8 minutes talktime.

A very cool gadget ;)
