No battery mouse
        
        The wireless mouse is a great invention, no doubt, but recharging 
batteries can be a drag (and using disposables is downright bad form). 
Genius is looking to improve on the current mouse solutions with its 
DX-Eco mouse — the big news here is that this mouse doesn't require 
batteries, nor does it require being centered on a power pad like other 
battery-free mice out there. Instead, it uses a gold capacitor, also 
known as an electric double layered capacitor (or supercapacitor). 
Rather than the chemical reaction found in standard batteries, gold 
capacitors rely on a storage cell that utilizes the absorption and 
release of ions. It was theorized a few years ago that this technology 
could power a mouse, but historically it has been used to provide backup
 sources of power (though the test mouse was also able to charge 
inductively, so it was completely cord-free). Apparently, the mouse can 
go a "full day" on one charge, but can be recharged in a mere three 
minutes — so while you likely won't see the longevity you get from 
traditional batteries, charging the mouse up should be a minimal 
inconvenience.
As for the rest of the hardware, the DX-Eco features seven buttons, runs
 over a 2.4GHz pico USB connection, contains two dpi settings (800 and 
1600) that are easily switchable by a button on top, and contains a 
"BlueEye" sensor, which helps the mouse function on a variety of 
surfaces.
