UT chemists turn seawater into fresh water with a battery [View all]
Chemists at The University of Texas at Austin and the University of Marburg in Germany are on the verge of a breakthrough in the worldwide quest for potable water.
The new method requires so little energy, in fact, that it can run on a store-bought battery.
By creating a small electrical field that removes salts from seawater, the chemists have found a new method for the desalination of seawater that consumes less energy and is dramatically simpler than conventional techniques, according to a press release from UT-Austin.
The process avoids the problems confronting current desalination methods by separating salt from water at a microscale.
