SODIS - solar water disinfecting with soda bottles and sunlight
Problem "More than one billion people drink unsafe water, WHO said in a report on water and sanitation released to mark World Water Day. Some 3.4 billion people, mostly children, die every year from water-related diseases, which include malaria, diarrhea and guinea worm." (1)
Summary "when transparent bottles are filled with water and placed horizontally on a flat surface for about five hours, the heat and ultraviolet rays of the sun kill illness-causing microorganisms in polluted water" (2)
