According to the World Health Organization 884 million people lack access to clean water; roughly one out of every eight humans. Although water desalination technologies exist, allowing impure or salty water to be cleaned, the facilities needed for this process consume a lot of energy and are costly. This means that clean water is denied to many of the world’s poor. Now however, with the creation of a successfully tested, portable solar-powered water desalination system, this fact may change. Professors Steven Dubowsky and Richard Wiesman of the Massachusetts Institute of Technology (MIT) guided the invention of a small reverse-osmosis system capable of producing 80 gallons of clean water a day. “The system is designed to be cost effective,” David Gabriel of the Environmental News Network explained, “It is made from standard parts…can be assembled and operated by local people…[and] can operate efficiently in a wide range of weather conditions.” The system also has a built in computer with sensors that will change variables depending on the weather. Researchers believe that a bigger version of the system may be able to produce around 1,000 gallons a day—greatly increasing the chance for access to clean water worldwide.
