Researchers use the ocean to recharge their batteries
When people think of harvesting energy from the oceans, it’s typically in the form of wave or tidal power, in which the motion of the water drives the production of electricity. A paper in Nano Letters suggests an alternate way to turn the ocean into power: using the fact that it’s salty. There have been a few ideas about how to extract energy from the salinity difference between salt and fresh …
