Mechanical Watches/Clocks and Lamps
Blue Angel eco-labelled products that work without using batteries or mains power are perfect examples of how alternative energy sources can be used in everyday life. The mechanically generated energy is stored in capacitors. As there is no need for batteries or accumulators resources can be saved and, moreover, heavy metals like cadmium can be avoided.
