Using Graphene, Lockheed Martin Wants To Turn Salt Water Into Drinking Water

A new Lockheed Martin project promises to cheaply and easily turn seawater into drinking water.

Graphene Pores When water molecules (red and white) and sodium and chlorine ions (green and purple) encounter a sheet of graphene (pale blue, center) perforated by holes of the right size, the water passes through, but the sodium and chlorine of the salt are blocked. David Cohen-Tanugi/MIT

It's surprisingly hard to find safe drinking water on Earth--this on a planet covered in water. A new project by Lockheed Martin hopes to change that, and do it cheaply. Using a graphene filter, Lockheed hopes to transform salt water into drinking water by the end of the year.
