Ship will use ocean's heat to make energy.

BENICIA. Calif. A World War ll vintage oil tanker has left the "moth-ball" fleet for conversion into the world's first electrical generating platform using the thermal energy of the ocean.
  The $25-million project to turn the U.S.S. Chepuchet into a floating power plantwas announced Thursday by the Energy Department.
   Conversion of the aeaworthy tanker. which was mothballed with dozens of liberty ships in the maritime reserve fleet in Suisun Bay, will be performed by a Newport Beech shipbuilding firm for Global Marine Development.
  Ocean thermal energy conversion involves evaporating a low boiling working fluid. such as ammonia, with the heat from warm surface seawater. The resulting vapor will then drive an electricity producing turbine generator.
  In the process. gaseous ammonia is passed through heat exchangers to be cooled by sea water drawn from 2.000 to 3.000 feet below the surface. The cold water condenses the working fluid into a liquid to begin the cycle again.
  Underwater cables will carry the electricity to shore from as far as 200 mil. according to project coordinator Dennis Neely.
  The Chepochet will carry a one megawatt generator and serve primarily as a testing center. Neely said. If the tests are successful. a 40-megawatt generator will be added.
   By the mid-19805, Neely predicted, larger generating units could supply the entire power needs of on island community in such places as Guam, the Philippines and Hawaii.
