Harvesting Power When Freshwater Meets Salty

Harvesting Power When Freshwater Meets Salty

Renewable Energy: Researchers boost power output from osmosis method that generates electricity from salinity gradients

Although sunlight and wind are two popular sources of renewable energy, some researchers would like to tap saltwater to produce electricity. They have designed methods that harvest the energy released when fresh and saline water mix, such as when a river meets the sea. Now one team has created a prototype device that increases the power output of such methods by an order of magnitude ( Environ. Sci. Technol. Lett.  2013, DOI: 10.1021/ez400117d). See more on:
