Parabolic solar cooker. Cooking pot being heated on a parabolic solar cooker. The mirrors lining the dish focus the sunlight and its heat onto the kettle. Solar cookers use no fuel and so are an environmentally friendly way to heat food and water. Photographed at a German Aerospace Agency (DLR) facility in Cologne, Germany.
