A method of producing electrokinetic power through forward osmosis

A method of producing electrokinetic power through forward osmosis

A power generation method for harvesting renewable energy from salinity gradient is proposed. The principle of the proposed method encompasses forward osmosis (FO) and electrokinetic phenomena. With the salinity difference between draw and feed solutions, FO allows spontaneous water flow across a se...
