A more efficient way to turn saltwater into drinking water

Water scarcity is a major problem across the world. "It affects every continent," says Amir Barati Farimani, an assistant professor of mechanical engineering at Carnegie Mellon University. "Four billion people live under conditions of severe water scarcity at least one month of the year. Half a billion people live under severe water scarcity all year." Yet even as people struggle without access to safe drinking water, there are oceans of undrinkable water right outside their doors. "71% of the world's surface is covered by seawater," Barati Farimani says. "So this is a very interesting contradiction." In order to combat this problem, Barati Farimani has focused his research on water desalination. This is the process in which salty seawater can be transformed into fresh water. Read more....
