Murakami Chair by Rochus Jacob

The serene back-and-forth movement of a rocking chair is nothing if not relaxing. It can also be useful and productive, according to Rochus Jacob. The designer’s Murakami Chair, a winner in designboom’s Green Life competition, uses the kinetic energy produced by rocking to power an attached OLED lamp. During the day, the Murakami chair stores energy in an on-board battery back. And in the evening, stored energy provides juice for the lamp. In that vein, the chair is reminiscent of other kinetic-energy powered everyday devices that we’ve covered, including the Kyocera OLED phone and the rain-powered umbrella.
