Platinum Nanomuscles Developed

An anonymous reader writes "The Institut für Nanotechnologie in Duisburg 'reports in the latest issue of the Journal Science that they have been able to use a tiny electric charge to flex a piece of 'nanoporous' platinum - an artificial sandwich of platinum atoms riddled with tiny holes. Nanomuscles weigh just one gram but can lift 140 grams, and are preferred to electric motors as they are far cheaper to produce: 50 cents each compared to US$300. They also make less noise and operate more smoothly. They could one day replace most small electric motors in toys, cameras and other devices.'"
