The Dynamic Lamp

Check out this cool lamp from designer Karin Johansson, the Dynamic Lamp.

The Dynamic Lamp features a large globe that can be spun around by your hands, inside the globe is a dynamo which converts the kinetic energy into electricity and the light the lamp.

Whilst this is a great concept,  I cant see it being very practical as you would spend the majority of your time spinning the globe rather than reading your book as the picture above.
