When energy from evaporation is scaled up, the researchers predict, it could produce electricity from floating power generators, or from rotating machines akin to wind turbines that sit above water, said Ozgur Sahin, Ph.D., an associate professor of biological sciences and physics at Columbia University and lead author of a paper detailing the research in Nature Communications.
