OTEC: Ocean Thermal Energy Conversion
By: Jackie Rowley
FUNDAMENTALS
75% of the Earth Covered by water Ocean water stores much more heat than the atmosphere Thermo-haline circulation creates temperature differences throughout Earth’s oceans

First OTEC system
Idea thought of by Jacques D’Arsonval, in 1881. French physician that contributed greatly to electrophysiology.
His student, Georges Claude, created the first OTEC system in Cuba in 1930.
OTEC System
Hot surface water, boils low boiling point liquid Boiling liquid turns turbine which generates electricity Electricity carried to land through underwater cable Deep cold water used to cool and condense liquid
Closed System OTEC -Use of low boiling point fluid 1 2000. Snowden, Paul, Kazuhiro Kitazawa, Masayuk i Mac Takahashi . Deep Ocean Water as Our Next Natural Resource. Chapter 3: OTEC Is Not A Dream. Tokyo. http://www.terrapub.co.jp/e-libr ary/dow/index.html
