Solar-powered desalination systems could bring water to disaster zones – Shanghai

It’s one of life’s most frustrating ironies that Earth’s surface is over 70 percent water, but most of that is undrinkable. Desalination is an important technology that may help unlock more drinking water, and now two independent teams have developed new types of solar-powered desalination systems using very different mechanisms.

The first of the two new designs comes from researchers at MIT and Shanghai Jiao Tong University. The team says the multilayer system has an impressive overall efficiency of 385 percent, producing as much as 5.78 L [
