Could Evaporation Be a Significant Source of Renewable Energy?

“In 2015, biophysicist Ozgur Sahin found a way to turn the process of evaporation into a renewable source of energy, building devices that lit up LEDs and electrified a toy car — all powered by changes in humidity levels in the air. Now, Sahin and colleagues at Columbia University have published a new paper in the journal Nature Communications that estimates evaporation on U.S. lakes and reservoirs could theoretically supply nearly 70 percent of the country’s electricity needs.”
