One sixth of the world's population has no access to safe drinking water, increasing their risk of waterborne diseases such as diarrhea, cholera, typhoid fever, Hepatitis A and dysentery.When attending an exhibition under the theme “H2O” at Milan's International Furniture Fair, Designers Alberto Meda and Francisco Gomez Paz learned about the SODIS system, a simple, low-cost solution for treating drinking water at a household level. Contaminated water is filled into transparent plastic bottles. When exposed to full sunlight for six hours, the pathogens in the water are destroyed.Meda and Paz decided to design a container that brings the best out of the SODIS system, and the result is Solar Bottle, which has one transparent face for UV-A + infrared rays collection and one aluminium color to increase the reflections. The high ratio surface/thickness of the low cost four liter container improves the performance of solar disinfection and its flat shape makes it stackable and facilitates storage. A handle makes it possible to regulate the angle for best solar exposition and ensures easy transportation.
