An osmotic power generator 1 comprises a first chamber 2 containing a first salt solution e.g. filtered seawater, and a second chamber 3 containing a second salt solution, with a higher salinity than the first salt solution. The second chamber 3 is separated from the first chamber 2 by a semi-permeable membrane 4. An electrical power generator e.g. turbine 5 is connected to the second chamber 3 and driven by pressurized fluid from the second chamber. Solid salt from a reservoir 8 may be added to the second chamber 3 to maintain the salinity of the second solution. The system may be used to provide power to an underwater installation, e.g. for charging a battery or capacitor. |
