Episode Teaser Image 
Episode Description 
Defense contractor Lockheed Martin has discovered a way to make desalination 100 times more efficient. And that could have a big impact on bringing clean drinking water to the developing world. The process is called reverse osmosis, and the material used is graphene -- a lot like the stuff you smudge across paper with your pencil. The new material could make for smaller, cheaper plants that turn salt water into drinking water, but it could also have uses in warzones.
