  5. First OTEC system Idea thought of by Jacques D’Arsonval, 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 http://www.google.com/imgres?imgurl=http://ffden-2.phys.uaf.edu/212_fall2003.web.dir/Yevette_Lancaster/open%2520otec.jpg&imgrefurl=http://ffden-2.phys.uaf.edu/212_fall2003.web.dir/Yevette_Lancaster/OTEC.htm&usg=__4BHbZGZTaiRYC8yzyTot1HARx5E=&h=277&w=353&sz=42&hl=en&start=0&zoom=1&tbnid=W10_4JFt_zIL4M:&tbnh=134&tbnw=171&ei=RqpvTey-D468sAP3vt20Cw&prev=/images%3Fq%3DOpen%2BSystem%2BOTEC%26hl%3Den%26safe%3Doff%26biw%3D1280%26bih%3D584%26gbv%3D2%26tbs%3Disch:1&itbs=1&iact=hc&vpx=491&vpy=90&dur=404&hovh=199&hovw=253&tx=152&ty=115&oei=RqpvTey-D468sAP3vt20Cw&page=1&ndsp=18&ved=1t:429,r:2,s:0

  9. Benefits of Open System OTEC if perfected -Desalinated water -Mariculture -Air conditioning http://www.google.com/imgres?imgurl=http://www.caribotec.com/OTEC_files/OTECuses.gif&imgrefurl=http://www.caribotec.com/OTEC2.htm&usg=__yaFbFBfp9q37MiJS6OuyAi1JCsg=&h=303&w=400&sz=56&hl=en&start=0&zoom=1&tbnid=MWS6Ny2jXtn5KM:&tbnh=138&tbnw=182&ei=5J5kTeLmIMqDtwej3emBBg&prev=/images%3Fq%3Dotec%2Bsystems%26um%3D1%26hl%3Den%26safe%3Doff%26sa%3DN%26biw%3D1280%26bih%3D581%26tbs%3Disch:1&um=1&itbs=1&iact=rc&dur=228&oei=hJ1kTfrQHYnhtgfU5siGBg&page=1&ndsp=18&ved=1t:429,r:3,s:0&tx=28&ty=72

  11. PROS CONS Promotes Global competitiveness and International Trade Enhances energy independence Has potential to mitigate green house gas emissions from burning fossil fuels • Reduces Carbon footprint by providing clean cost effective energy • Produces desalinated water for industrial, agricultural and residential uses
