A test of liquid flow through semipermeable membranes was done in an attempt to utilize the salinity difference between sea water and pure water for electric power generation. Pure water and salt water were filled separately into two chambers divided by semipermeable membranes of a reverse osmosis (RO) module. Salt water was forced to flow along the semipermeable membranes by a pump. Pure water was passed through the semipermeable membranes and into the salt water chamber by osmotic pressure. The pressure difference and the flow rate across the flow control valve installed in the pipeline of the pure water chamber were measured. The valve served as a load for a water turbine. Compared with theoretical considerations, the measured values of pressure difference and flow rate suggest the high possibility of generating electric power by utilizing the system proposed here.
