Finding ways to create clean drinking water where there is none is a field of constant innovation. Desalination, the process of filtering seawater to make it fit for human use, is perhaps the most common and researchers around the globe are on a quest to bring cost-effective and portable desalination technology to rural areas where it is desperately needed. So it’s exciting news that researchers at Alexandria University in Egypt have developed a promising new method that can turn salt water into fresh water in just a few minutes. The new Egyptian method relies on salt-attracting membranes and vaporizing heat...
