From the article:

Water scarcity is a growing problem around the world. Desalination of seawater is an established method to produce drinkable water but comes with huge energy costs. For the first time, researchers use fluorine-based nanostructures to successfully filter salt from water. Compared to current desalination methods, these fluorous nanochannels work faster, require less pressure and less energy, and are a more effective filter.

From the article:
Many arid, coastal regions of the world rely on desalination to get potable water from the salty seas. This reliance is going to increase as climate change triggers droughts and water scarcity. But desalination is costly, uses a lot of energy, and produces waste brine—a concentrated soup of salt and chemical—that can harm marine ecosystems.

A new desalination device that converts brine into useful chemicals could help. Its developers at Stanford University say it could make desalination affordable and environmentally benign.
