Empower rocking chair

Another highlight of the Greener Gadgets Conference, these ergonomically designed rocking chairs by Empower allow you to sit back, relax and power your gadgets all at the same time. Made for public spaces like airports or waiting rooms, they collect kinetic energy from your movement. That energy is then released via a USB connection, so you can plug in any of your compatible devices to charge them while you rock back and forth.
