It's still in concept
form at the moment, but America's own Adele Peters just might have a winner with Corky. This obviously cork-based mouse relies on "piezoelectric elements to generate energy every time you click or move it around on your desk," meaning that nary a battery would ever be used to power it. In case that's not sustainable enough for you, the whole thing is made from easily recyclable materials, so it shouldn't mar Ma Earth when it gets tossed at the end of its useful life. Too bad that design has been trumped forty times over by more ergonomic options
, but hey, there's always v2.0.
