An eye-opening research might have just taken the lid off an overlooked process of producing clean electricity, enough to power 70 percent of the U.S.

A new study by researchers at Columbia University found that the simple evaporation of water from the U.S. lakes and reservoirs could rival solar and wind power if a suitable conversion method can harness the energy from vapors, notes Research Gate.

According to the study published in journal Nature Communications, the team has devised evaporation engines that will hang over water surfaces and perform work through a cycle of absorbing and expelling vapors, writes Gizmodo.
