Ocean thermal energy conversion (otec)

  2. 2. <ul><li>68.18% of the Earth is covered by the Oceans </li></ul><ul><li>These Oceans are constantly being heated by the sun </li></ul><ul><li>Create currents </li></ul>
  3. 3. <ul><li>(THC) </li></ul><ul><li>“ Circulation that is driven by global density gradients created by surface heat and fresh water fluxes.” </li></ul><ul><li>Cooling and currents from the wind </li></ul><ul><li>Ice near the poles cool the water </li></ul><ul><li>Evaporation changes the water content </li></ul><ul><li>The sun is constantly heating the surface of the ocean </li></ul><ul><li>Fresh water from river mouths changes its content </li></ul>
  4. 5. <ul><li>Prime place for temperature difference </li></ul><ul><li>Temperature difference is like stored up potential energy </li></ul><ul><li>Stirling Engine http://phys106spring10.pbworks.com/Stirling-Engines </li></ul>
  5. 6. <ul><li>“ National Institute of Ocean Technology and Dempo Shipbuilding” </li></ul><ul><li>Rankine Cycle </li></ul>
  6. 7. <ul><li>Closed system that uses temperature difference </li></ul><ul><li>Boils a liquid and cools it to gas under the right pressure </li></ul><ul><li>Generates electrical energy with an efficient turbine </li></ul>
  7. 8. <ul><li>Must use a liquid with a low boiling temperature </li></ul><ul><li>Propane (under the right pressure) </li></ul><ul><li>Uses the warm surface water heated by the Sun to boil the propane </li></ul><ul><li>Colder denser water at the bottom of the basin to condense the propane </li></ul>
  8. 10. <ul><li>The sources of temperature difference for this system are endless </li></ul><ul><li>The ocean currents are not going to stop any time soon </li></ul><ul><li>Works 100% coal and oil free </li></ul><ul><li>Only makes sense to implement </li></ul>
