1. CARTER DENNY OCEAN TEMPERATURE GRADIENTS

2. Ocean Temp Gradient also know as Ocean Thermal Energy Conversion(OTEC) is process that involves using warm surface water to vaporize ammonia and the vaporized ammonia(the working fluid) spins a turbine which generates electricity. The cold water that comes from deeper parts of the ocean cools down the ammonia to a liquid state to repeat the process again. https://www.youtube.com/watch?v= gMy-PjPFsCQ HOW IT WORKS

3. Turbine Working fluid Warm and cold ocean water a water pump Condenser and Boiler WORKING PARTS

4. The efficiency of OTEC electricity ranges from 3%-8% depending of the temperature difference in the warm and cold water. EFFICIENCY

5. Most OTEC power plants are found near oceans or in the ocean in tropical regions like Hawaii, the Bahamas, Hainan, and the Virgin Islands. WHERE IT IS LIKELY TO BE FOUND.

6. There are very little risks involved with OTEC. One risk could be that the working fluid(ammonia) which is a CFC could leak and pollute the air. OTEC is a very low risk source of energy. POTENTIAL PROBLEMS

7. ADVANTAGES AND DISADVANTAGES Advantages Cleaner, no air pollution Decreases reliance on foreign oil Reduces CO2 emissions Has the potential to meet all the world’s energy needs Disadvantages More expensive than power from fossil fuels Must be in an area where surface water is warm enough to vaporize the working fluid Pipes could damage coral reefs Less efficient than coal
