Water evaporation is the largest power source in nature, Sahin said. "Sunlight hits the ocean, heats it up, and energy has to leave the ocean through evaporation," he explained. "If you think about all the ice on top of Mt. Everest - who took this huge amount of material up there? There's energy in evaporation, but it's so subtle we don't see it."
But until now no one has tapped that energy to generate electricity.
As Sahin pursued the idea of a new humidity-driven generator, he realized that Mahadevan had been investigating similar problems from a physical perspective. Specifically, he had characterized how moisture deforms materials, including biological materials such as pine cones, leaves and flowers, as well as man-made materials such as a sheet of tissue paper lying in a dish of water.
