"Portable wireless mice have a problem: most of them rely upon disposable batteries, which often wind up in landfills as e-waste. Adele Peters’ Corky mouse aims to change all that — it’s a kinetic energy-harvesting mouse that is powered with a flick of the wrist. One of 18 finalists in this year’s Greener Gadgets Design Competition, it’s also made from 100% recycled plastic components and recycled and biodegradable cork.
The Corky mouse uses piezoelectric elements to generate energy every time you click or move it around on your desk – even rolling the scroll wheel will generate a few watts. We’ve seen many watches that harvest kinetic energy, so the technology is definitely available, and it makes a lot of sense in this application. Since computer mice function through movement, why not harness that expended energy?" inhabitat
