By creating a small electrical field that removes salts from seawater, chemists at The University of Texas at Austin and the University of Marburg in Germany have introduced a new method for the desalination of seawater that consumes less energy and is dramatically simpler than conventional techniques. The new method requires so little energy that it can run on a store-bought battery. The voice is Kyle Knust, a graduate student in the lab of Richard Crooks, professor of chemistry at The University of Texas at Austin.
