In an article for Wired about desalination technologies, Eric Niiler features Prof. Rohit Karnik’s work developing single-layer membranes from graphene that could make desalination more efficient. “If we want quantum leaps in performance, we have to look for other materials,” says Karnik.
Eleanor Goldberg writes for The Huffington Post that a team of MIT researchers has developed a solar-powered desalination system that could help bring clean drinking water to rural areas. The researchers hope to eventually release a model that could provide clean drinking water for an entire village, Goldberg reports.
Washington Post reporter Joby Warrick writes that a team of MIT engineers has won the Desal Prize for a solar-powered desalination system they developed. “The system, when fully operational, can supply the basic water needs of a village of between 2,000 and 5,000 people,” Warrick explains.
A team of MIT researchers won the grand prize in a competition that challenged participants to develop sustainable desalination technologies, reports Jeff Daniels reports for NBC News. The MIT researchers designed a solar-powered "electrodialysis reversal system that desalinates water using electricity.”
In an article for Popular Science, Mary Beth Griggs reports that a team of MIT researchers won the Desal Prize, a competition judging the effectiveness of new desalination systems. The MIT team developed a system that uses solar panels to power “a system that removes salt from the water through electrodialysis.”
Boston Globe reporter Hiawatha Bray writes about how Prof. Amos Winter and graduate student Natasha Wright are testing their solar-powered desalination system in a competition aimed at finding cheaper and more efficient ways to provide clean water to the developing world. “It’s a two-billion-person problem,” says Winter. “That’s a pretty motivating problem.”
Nidhi Subbaraman of BetaBoston reports that MIT researchers have proposed a new solar-powered, desalination system for purifying groundwater. “Wright and Winter argue that for the low levels of salt in the groundwater in up to 60 percent of rural India, they can extract enough power from solar panels to run their electrodialysis setup,” writes Subbaraman.
Daniel Akst of The Wall Street Journal writes about new MIT findings that could make pressure-retarded osmosis (PRO) a more feasible technique for producing power from two streams of different salinity.
Cynthia Graber of Scientific American reports on the new MIT technique to use solar energy to generate steam. Graber reports that the new system reaches, “85 percent efficiency in converting the solar energy into steam."
In an interview, MIT Prof. Gang Chen described the potential applications of his new spongelike structure to Kiley Kroh of ClimateProgress. "Think about water treatment, desalination or treating wastewater," Chen said. "One typical way is to evaporate the water, condense it; of course, you need an energy source to do that. In this case, if we can use solar energy, it could produce better technology."
“A new technology creates steam by harnessing solar energy, using a relatively cheap sponge-like material, and it does it with greater efficiency that ever previously achieved,” writes Douglas Main in a piece for Popular Science about a new solar sponge created by MIT scientists.
