THE WATCHISMO TIMES: Big Changes in the Atmosphere - Jaeger LeCoultre's Atmos 561 by Marc Newson
Saw something interesting today on this blog about a watch that is powered by the changing temperature. No more batteries required and the waste from discarding them could be forgotten. Green? Certainly, though winding clocks would run this one close in green cred. That said, the inventiveness shown in this design is fascinating and I hope that there are more such ideas used to power other devices.
