Solar-powered desalination unit shows great promise

Freshwater accounts for only about 2.5% of water on Earth, so much of the world experiences serious water shortages. Scientists report the development of a highly efficient desalination device that uses a titanium-containing layer capable of absorbing solar energy. When sunlight strikes the layer, it heats rapidly and vaporizes the water. By placing the unit in a transparent container with a sloped quartz roof, the water vapor can be condensed and collected.
