Solar Bottle Uses Sun to Purify Water
These new bottles are designed to take advantage of the "SODIS
" method of water disinfection—using the heat and ultraviolet radiation from the sun to purify water—by putting a layer of black, sun-absorbing material opposite the clear side of the bottle. The SODIS method can be used with generic clear water bottles and a painted black tin roof, but these "Solar Bottles" are designed to be entirely portable and feature a clever notched handle that can make it easier to get the water directly in the sun's rays.
Each Solar Bottle can hold a gallon of water and can be held back-to-back for easy transport.
