In places where there is little access to reliable electricity, there is still access to sunlight. The Solar Bottle Bulb utilizes recycled material and provides light equivalent to that of a standard light bulb. A plastic bottle is filled with water and bleach (which prevents microorganism growth) and then affixed into a roof. Sunlight is refracted by the water, which lights up the room!
