Providing safer drinking water to those in need may be a little easier. According to Penn State researchers, a new desalination technique is able to remove salt from water using less energy than previous methods.

"Globally, there is reduced access to fresh water," said Bruce Logan, Evan Pugh University Professor in Engineering and the Stan and Flora Kappe Professor of Environmental Engineering. "More and more, the waters that are being used are impaired, either due to salt or other contaminants, so we are seeing an increasing need to rely on less optimal water sources."

Since this world has an abundant amount of salt water, it has never been anything but the cost of the energy to desalinate it that is preventing desalinization plants all over the place.
