Removing salt from seawater with small electrical field

Scientists from the University of Texas at Austin and the University of Marburg in Germany, have introduced a new method for the desalination, by creating a small electrical field that removes salt from seawater.    Watch the video…

The new electrochemically mediated seawater desalination method, consumes less energy and is dramatically simpler than conventional techniques. It requires so little energy that it can run on a store-bought battery.

Richard Crooks, a chemistry professor at the University of Texas at Austin, said:

“The availability of water for drinking and crop irrigation is one of the most basic requirements for maintaining and improving human health.

Seawater desalination is one way to address this need, but most current methods for desalinating water rely on expensive and easily contaminated membranes. The membrane-free method we’ve developed still needs to be refined and scaled up, but if we can succeed at that, then one day it might be possible to provide fresh water on a massive scale using a simple, even portable, system.”

Okeanos Technologies has been created to start developing the technology.
