FUNDAMENTALS

• 75 of the Earth Covered by water
• Ocean water stores much more heat than the
  atmosphere
• Thermo-haline circulation creates temperature
  differences throughout Earths oceans

First OTEC system

• Idea thought of by Jacques DArsonval, in 1881.
• French physician that contributed greatly to
  electrophysiology.
• His student, Georges Claude, created the first
  OTEC system in Cuba in 1930.

6
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

7
Closed System OTEC
-Use of low boiling point fluid
8
Open System OTEC

• Use of Water as fluid
