This Simple Filter Makes Seawater Safe To Drink

By Brian Spaen

Over two billion people in the world don’t have access to safe, clean drinking water. This leads to a lack of proper hygiene, the spread of many diseases, and premature death of kids growing up in developing countries. In order to increase clean water reach, Australian scientists have developed a cheap graphene material that can effectively filter salt and dirt from water.

Graphene is a material that has numerous useful properties, one of them being an ability to repel water. At the same time, it can absorb salt and dirty materials in water, essentially creating a filter. What's the problem? It can be expensive to create the material, and can use a lot of energy.

Scientists at the Commonwealth Scientific and Industrial Research Organization (CSIRO) have developed a cheaper graphene material called “Graphair.” It retains the same properties as traditional graphene, but it’s made out of soybean oil. What's so important about this development? It's both less expensive and more eco-friendly.
