JMSTC PRESENTED
OTEC EXPERIMENT IN ECOR GENERAL ASSEMBLY
In a recent general assembly of
Engineering Committee on Oceanic Resources (ECOR)held in Halifax, Nova Scotia,
Canada during September 20-22, 1990, the Japan Marine Science and Technology
Center (JMSTC), made a presentation on the
"Current Ocean Energy Systems in
Japan". In the presentation, the speaker indicated that many organizations in
Japan have studied the ocean energy utilizations during the past 15 years, and
considerable amounts of technical data have become available. He emphasized that
the technology needed for the operation of ocean energy systems has also been
developed and tested in various experimental plants. Their current efforts are
placed on the reduction of the cost including the development of
multi-utilization systems specially for those incorporated with the ocean
thermal energy and wave energy conversions. The JMSTC felt that the Japanese
have now paid more attention to the utilization of natural energy because it
cuold be the answers for solving the environmental problems in Japan. Some of
the recent projects they conducted are listed below:
