Research Finds Energy in Salt Water

摘要

Areas where river water and seawater converge are not typi-cally the first place one thinks of as a renewable energy opportunity,but researchers from MIT are assessing hydroelectricity's place in the burgeoning renewable energy grid. The team studied a new method of power generation called pressure retarded osmosis (PRO), where water streams with different salinity levels pass across a barrier and create a flow that can be sent through a turbine to produce power.
