Sun-heated surface water and deeper colder currents creates power

This is a well-developed power source This power source alone could produce all

the power the world will ever need We have no “energy crisis” whatever, just

an ignorance - or a laziness - crisis

CLOSED CYCLE

Open Cycle Open Cycle

Surface water is brought to a boil by removing air from the boiler and thus lowering the pressure.

There is no heating. The steam runs a turbine running a generator. The steam is condensed in a condenser into

which cold water is pumped from deeper layers. The condensed water can be tapped as fresh

water.

Closed Cycle Closed Cycle

The warm surface water heats a working fluid — ammonia or another refrigerant.

The refrigerant boils and this vapor runs the turbine, after which it is condensed by cold water pumped from below.

There is no heating. The turbine runs a generator to produce

electric power.

Plant Types Plant Types

The two types will be suitable for different conditions and requirements.

Both open and closed plants may be built on shore.

Both types can be built as ships, either anchored or free-moving in the ocean. These may move to where maximum thermal

difference may be found.

OTEC History OTEC History

Ocean thermal plants were first discussed by French, Italian and US engineers and scientists in 1881.

In the Twenties, the French engineer George Claude built three plants in Paris, Ougre in Belgium (producing 60 Kilowatts) and in Cuba, producing 22 Kilowatts for 11 days.

In 1942, the French government began research of systems and components; designed and partly built a plant in West Africa producing 7500 Kilowatts plus fresh water.

In the late Forties, an American engineer studied the French work and caused the National Bureau of Standards and later the University of California at Berkeley to build and test plants.

The oil crisis in the 1970’s caused seven major US universities and five large firms to join in this work.

Ocean “fuel” is free: The ocean itself.
