World Health Organization reports that water can be purified using sunlight and plastic bottles reducing deaths from unsafe drinking water in developing countries.
"A do-it-yourself technique of disinfecting water with sunlight and soft-drink bottles could save hundreds of thousands of lives a year, the World Health Organization said Thursday.In a campaign to reduce deaths from unhealthy water in developing countries, the UN health agency is promoting a nearly cost-free process called Solar Water Disinfection, or SODIS. The process is simple: 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."
