Solar-Powered Water Purifier

WWF has selected Solvatten, a solar-powered water purifier, as a 'Climate Solver', recognizing this Swedish invention's potential to reduce green-house gas emissions. Given the number of people worldwide currently treating their water by boiling with firewood, WWF estimates that, with widespread distribution, Solvatten could be reducing CO2 emissions by 26 million tonnes per year by 2020. The use of Solvatten can reduce dependence on firewood and other fuels, since it uses the sun's rays.
