ABSTRACT:
A method and apparatus for transferring cold seawater from lower ocean depths upward toward sea level for use in ocean thermal energy conversion systems is disclosed wherein an in situ desalination process is utilized to create a density differential between the desalinated water and the surrounding seawater. The desalinated water being of a lesser density than the surrounding seawater, rises naturally upward through a conduit and is utilized as a heat transfer medium in the ocean thermal energy conversion system. The desalinated water, which is a byproduct of the energy conversion system, may be utilized for domestic consumption or alternatively dispersed into the near surface region (photic zone) of the ocean to increase the nutrient concentration therein.
