Droplets that leap from a water-repelling surface pick up a charge and could one day make power plants run more efficiently, according to a report published in Nature Communications. "The concept of jumping droplets is not new, and we have been working on it and publishing papers for a while now," said MIT postdoctoral associate Nenad Miljkovic, the study's co-author. "However, none of the previous studies (including ours) had any idea that the droplets were charged." The researchers say that by coating condensers with a superhydrophobe, a substance that repels water, the charged droplets will bounce away more quickly, speeding up power plant production.
