Another Kind of Hydropower From Rivers

May 30, 2011 | 1 Comment

At Stanford University researchers have developed a “rechargeable battery” that uses freshwater and seawater to create electricity. Aided by nanotechnology, the battery employs the difference in salinity between fresh and saltwater to generate a current. A power station might be built wherever a river flows into the ocean. Yi Cui, Associate Professor of Materials Science […]
