Wireless mouse needs no batteries

While wireless mice of today come with a pretty decent battery life that last up to half a year before requiring a replacement, you never quite know when the exact moment might arrive, leaving you to the mercy of a touchpad during an important business presentation. The Battery Free Wireless Mouse aims to change that, where all the power required to run the mouse is provided by the mousepad. The only caveat would be having the mousepad hooked up to a powered USB port at all times. The concept plays on using the mousepad as a conductor, channeling just enough juice to keep your precious pointing peripheral powered at all times. The Battery Free Wireless Mouse retails for approximately $25.
