Gallery: Nano Water Chip Could Make Desalination Affordable for Everyon...

 

With freshwater declining throughout the globe, desalination looks increasingly attractive, but current technologies are expensive, demand far too much energy and are prone to contamination. Now researchers from the University of Texas at Austin and the University of Marburg in Germany have developed a “water chip” that creates a small electrical field that separates salt from seawater. The technology, which is still under development and works at the nano scale, uses so little energy it can run off a store-bought battery!
