About 71 percent of the Earth’s surface is covered by water, but unfortunately most of that liquid nourishment isn’t suitable for drinking because it’s salt water found in the oceans. Removing salt from water is not an easy process, either. Current desalination technology requires a high amount of energy, making it prohibitively expensive — especially in developing nations. But don’t worry: a team of researchers at Alexandria University in Egypt have bypassed these power-hungry methods and created a simple filtration technique; the details of which are described in a research paper published last month in Water Science and Technology.
