Desalination Could Be the Solution to California’s Drought

One of the drawbacks of desalination is the enormous amount of energy it takes to turn salt water into fresh water. A potential solution has launched in the dry heat of California’s Central Valley, where a pilot project is using solar energy to operate a new kind of desal system. Plants that can handle brackish water, such as pistachios and wheatgrass, dot the landscape, watered by reclaimed runoff. The salty stuff can now be turned into fresh water by a row of curved mirrors that bend the sun’s rays, focusing it on long tubes containing mineral oil.
