New technology uses sunlight to provide clean drinking water

Since large desalination plants are powered by carbon-emitting fossil fuels and cost billions of dollars to build, researchers are trying to use the sun’s heat more directly to remove salt and other contaminants from seawater and groundwater. Thanks to novel materials and designs, the process is likely to get cheaper, simpler and portable enough to make high-quality desalination far more accessible worldwide. Learn how.
