Clean drinking water has always been a major issue in many developing countries, but with the onset of climate change and droughts, this may become a problem for industrialized countries as well. There is a simple solution for clean water: clay. Tony Flynn with the World Vision charity and Potters for Peace have discovered people everywhere can drink clean water with the materials around us.
Tony Flynn, a master potter and scientist, has created a simple to create water purifier out of incredibly simple materials found almost anywhere in the world. The filter is created with clay, organic materials (coffee grinds or rice), water and manure. The straw and rice are mixed in with the clay and water and then fired over some burning manure. The organic materials are burned away during the firing process and create small passages in the filter that allow water, but not pathogens, to pass. This filter effectively removes 96.4-99.8% of E. Coli in water [Source: ANU]. One of these filters can great a liter of drinkable water in only two hours.
