Battery-free wireless mouse

A wireless mouse that does not run on battery power? Apparently, that is made possible with the Battery-Free Mouse from A4Tech. This computer peripheral is powered by some voodoo hoodoo and a magical incantation – we’re kidding, it uses electromagnetic induction and works perfectly fine like any other optical mouse as long as it remains on the special USB mousepad. Other specifications remain ordinary – an 800 dpi optical resolution, a scroll wheel, and left- and -right click buttons. One major gripe with wireless mice are their weight, but with this Battery-Free Mouse, things look set to change. It is available in Korea for approximately $21 after conversion.
