Rocking Chair Uses Motion to Power Attached OLED Lamp

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.

According to Jacob, “I was looking for opportunities to generate energy through activities we naturally do. The final result is a rocking chair that enables the user to experience production and consumption of electricity in a gentle and rewarding way. An abstract process becomes tangible and eventually cultivates natural awareness. Complexity is covered by simplicity.”

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.
