Genius introduces the DX-ECO wireless, battery-free mouse
 

Genius has this week announced a new addition to its peripheral offer, a wireless mouse called DX-ECO which doesn't need battery changing. It does require power of course but that's provided by a capacitor which can be charged in just three minutes (you get 4 hours of use per charge).
