This has the potential to be a real game changer. Among all the other problems out there, one very pervasive issue that gets intermittent lip service is potable, or the lack thereof, water. A portable desalination device could save lives in a variety of situations.

The portable system could also be used in remote areas where supplying energy and clean water can be logistically complex and expensive, such as desert locations or farms and small villages in developing countries.
Led by Steven Dubowsky, a professor in both the Department of Mechanical Engineering and the Department of Aeronautics and Astronautics, and graduate students Amy Bilton and Leah Kelley, the group built a small prototype of the system last spring to test algorithms they had developed to run it. They have since demonstrated that the prototype is capable of producing 80 gallons of water a day in a variety of weather conditions. They estimate that a larger version of the unit, which would cost about $8,000 to construct, could provide about 1,000 gallons of water per day. Dubowsky and his students also estimate that one C-130 cargo airplane could transport two dozen desalination units — enough to provide water for 10,000 people.
The team presented a paper reporting preliminary results about its prototype system last week at the EuroMed 2010-Desalination for Clean Water and Energy Conference.
