In a new study published in Nano Letters, […]

Oasys Water, a company specialized in desalination, comes with a solution to the scarcity of water in some regions and also cuts the costs for producing it.

They want to use the difference between salty and fresh water through osmosis in two different manners and say that their solutions could suffice the entire world's energy needs. The New Scientist joined them both in an interesting case study.
