Stanford researchers use river water and salty ocean water to generate electricity
This is not an osmotic pressure power generator, rather a battery with flushable electrolytes that determine if it is in a charge or discharge phase. The added trick is using nanorods to increase the electrode area. Salinity is key here, meaning it doesn't have to be really clean freshwater, but the battery prefers brine over saltwater or brackish water. Hrm, I wonder if you could do this as secondary power generation for water desalination plants located on rivers next to oceans or salt lakes, using freshwater sources and desalination output brine?
