  • 1. OTECOCEAN THERMAL ENERGY CONVERSION by Miguel, Luca and Spencer
  • 2. OTECwe are investigating ocean thermalenergy conversionthis resource is viable when startedbecause in the process of creating energyit does not take up any materials
  • 3. OTEC in Santa Barbaraif you were to set up an OTEC power plant in SantaBarbara you would need to set it up in a place with adifference of about 20 degrees Celsius, and in betweenthermoclines.we are not sure if Santa Barbara can provide this typeof locationit takes money and not many people are willing toinvest in a source of energy that has only been testedonce
  • 4. OTEC in Santa BarbraWe do not believe that OTEC should beused in Santa Barbra, because it has notbeen tested on a significant basisuntil it has been tested and, the OTECpower plant has been proven to beeffective, with a less probability ofproblems we should not invest
  • 5. Historyattempts to develop OTEC Technology started in1880’sJacques D’ Arsonval proposed the idea of convertingdifferences in water temperature into electricityGeorges Claude built the first OTEC plant inMatanzas bay, Cuba in 1930it generated 22Kw of electricity with a low pressureturbine, however it did not produce a net power.
  • 6. traditional energy sourcesfossil fuels are oil, coal, and natural gasfoils fuels have a very harmful impact on the planetfossil fuels are not viable or renewable because theytake millions of years to form,and reserves are beingdepleted faster than the new ones are being reformedwe should not continue using traditional energy
  • 7. traditional energy chart
  • 8. OTECOTEC is found in the oceanthe way OTEC creates energy is it has ammonia in itstubes, ammonia has a boiling temperature of -28f ,when warm water is run by the ammonia it makes theammonia evaporate, the evaporated ammonia turns agenerator. The ammonia is moved to lower water wereit condenses and turns back to a liquid state. Theprocess is repeated and the cycle continuously runs
  • 9. the energy is found in the temperature ofthe sea water. The temperature makesthe ammonia turn into steam which turnsthe turbine creating electricity
  • 10. OTEC Plant
  • 11. fun factsthis technology is not yet utilizedthe first experiment was made off of asmall boatthis has only been done once
  • 12. traditional vs otecthe concept is the same, a liquid isheated and evaporates which turns aturbine, which creates electrical energythe difference is that OTEC does notrequire any materials to be burned orheated to create enough energy to powerthe generator.
  • 13. Future of OTECthis is a very complicated and expensiveenergy but as technology improves itcould have a big impact on the future’senergy sources.
  • 14. Where is OTECthe question should be when, as of nowthere is not currently an OTEC powerplant that is in usethe only place it was built so far was of asmall boat in the sea. Hawaii, however,is currently looking into OTEC as apossible energy source
  • 15. The Pros of OTECOTEC is a reliable source of energy.OTEC produces energy 24/7 unlike windor solar power, that depend on theoutside conditions to function.
  • 16. DependabilityOTEC does not rely on fossil fuels tofunction, there for it is not subject toprice fluctuation. OTEC power has an easily predictableinput to output ratio.
  • 17. More ProsThe ocean covers more than 70% of theplanet and each day it absorbs the solarequivalent of several billion barrels ofoil.If OTEC could capture just .1% it wouldproduce enough energy to power 20USAs.
  • 18. Were it can be usedOTEC is a great source of energy forsmall islands that rely mostly onimported oil.It is also a great reliable source ofenergy for military out posts like guam,so that their source of energy cannot becut off
  • 19. OTEC disadvantages•there is only so many parts of the ocean the can do it at.•Despite the advantages of temperature moderation, the OTEC plants can alter and maybe damage the surrounding ecosystem•OTEC plants must be located where a difference of about 20o C occurs
  • 20. •Ocean thermal energy conversion requires a lot of money up front.•Ocean depths must be available fairly close to shore• No energy company will put money in this project because it only had been tested in a very small scale• Construction of OTEC plants and lying of pipes in coastal waters may cause localized damage to reefs and near-shore
