At the intersection of saltwater and freshwater could be a jackpot of power, says an MIT research team. Enough, the team claims, to potentially power the Deer Island Waste Water Treatment Plant in the Boston Harbor.The team is investigating a method of power generation called pressure retarded osmosis (PRO), where two streams of different salinity are mixed to produce energy. According to a press release from MIT, a PRO system would take in river water and seawater on either side of a semi-permeable membrane. Through osmosis, water from the less salty stream would cross the membrane to a pre-pressurized saltier
