    Default Freshwater from salt water using only solar energy

    Jeff Fitlow/Rice University
    June 19, 2017

    A federally funded research effort to revolutionize water treatment has yielded an off-grid technology that uses energy from sunlight alone to turn salt water into fresh drinking water. The desalination system, which uses a combination of membrane distillation technology and light-harvesting nanophotonics, is the first major innovation from the Center for Nanotechnology Enabled Water Treatment (NEWT), a multi-institutional engineering research center based at Rice University.

    NEWT's "nanophotonics-enabled solar membrane distillation" technology, or NESMD, combines tried-and-true water treatment methods with cutting-edge nanotechnology that converts sunlight to heat. The technology is described online this week in the Proceedings of the National Academy of Sciences.

    Glad to see the federal government is backing some "out-of-the-box" thinking. I did not know Rice University is a major research university!!

    Here is another alternate energy, tidal desalination article I just now discovered from the morning news, about Atmocean: http://www.enr.com/articles/42354-wa...ular-and-cheap

    As the need grows and technology improves, I would expect them to become more efficient, smaller and cheaper… Just as solar panels have become.
