The Dynamic Lamp by Karin Johansson.

"My Dynamic Lamp is a part of the wireless society," Johansson says. "It doesn't need any power supply or batteries; it just works with your own energy. It is based on the idea of producing your energy where you are, instead of transporting it in all directions across the earth. The sole by-product is exercise."
