Karin Johansson’s lamp is a wonderful and eco-friendly concept that uses the globe of the earth as your source of light and the kinetic energy of your hands as the source of power. A dynamo placed inside the globe converts the kinetic energy to light when you spin it. It’s amazing how the globe glows without the aid of power supply or batteries. The concept is designed to facilitate the generation (conversion rather) of energy where you are, instead of transporting it in all directions across the earth. In the process, the human body is made to do some exercise too. Check out the video below to see it in action.
