  • Forward Osmois uses a "draw solution" and a membrane to allow water molecules to flow from a lower concentration of salt (seawater for example) to a highly concentrated salt solution (called the "draw solution"). The idea isn't new, but has been largely discarded in the past because the salts used in the draw solution couldn't be driven off the water effectively whether the challenge was economics or purity. Oasys Water founder, Robert MsGinnis, claims to have solved this problem and if he's correct, he may have one of the great engineering achievements that we've seen in a while.
