Ok! sorry for being late, i have been busy.. just to give you a rundown to those of you who are not familiar with google docs, it automatically saves every five minutes or so, so dont worry if you forget to save, it will automatically save for you! other than that it really works just like word or open office for the most part. ok, in case anybody didn't get all the notes we wrote down, here is a photo of my notes along with some of your thoughts and comments * Hey guys, so I made this outline for our topic so it could maybe be helpful when reading the chapter or when you’re looking up information. Feel free to add anything on or take something out or any comments on it. Is this the main document? A. Tides
­ what are tides and how are they made.
­ how are they used for generating energy.
­ La Rance facility in France
­ other energy generating facilities. B. Waves
­ what are waves and how are they formed
­ ways they could be used for generating energy
­ experiments/ demonstration projects with wave motions C. Ocean Currents
­ what are they
­ how are they made/ what drives them (ex. thermohaline circulation page. 254­256)
­ how are they used for generating energy D. Thermal Properties
­ roughly 80% of the energy that the Sun emits to the Earth is absorbed and stored by oceans. ­ ­only 33ft of the ocean absorbs solar energy
­ This energy can be harnessed from the ocean's warm surface water and cold water of the deep
­ Recent, major exploitation of ocean's temperatures is called OTEC

­ El Nino Southern­Oscillation(ENSO)
­ El Nino Conditions

E. Ocean thermal conversion (OTEC)
­ process that uses temperature difference between the surface and the deep of oceans to generate clean drinking water and electricity. Advantages of OTEC
­ It does not contribute to pollution from fossil fuels; environmentally friendly
­ land­based plants produce electricity and water for human consumption and food production Disadvantages of OTEC
­ Limited access. Only accessible and obtainable in costal areas

Key terms:
1.
Wave energy
2.
Upwelling
3.
Downwelling Textbook: pg. 374 new brunswick and nova scotia are great locations for harnessing tidal energy, it looks like it has somthing to do with the height between low and high tides which is why the locations listed are best for tidal energy. i think we should use the picture shown on this page because it shows how they get the energy, we just need to comprehend how it works so we can properly explain the picture. we should talk about how we are working to harness the motion of ocean waves, and explain how it differs from tidal waves because i am sure people will ask what the difference is. wave energy is relatively new. the textbook gives us the surface of what we need to include in our powerpoint which is great, because all we have to do is research the topics a little more in depth and include our finding in the power point.

unfortunately i will not be able to make it to our meeting this thursday because i got called in to work, i was hoping you guys could just let me know what you all talked about and let me know when the next meeting is, (i cant do thursday) i am available all week except weekends and now thursdays. team, this is a great video to keep in mind regarding oceans, it’s a bit lengthy (about 11 minutes) Wave Energy Technologies
There are three main types of wave energy technologies. One type uses floats, buoys, or pitching devices to generate electricity using the rise and fall of ocean swells to drive hydraulic pumps. A second type uses oscillating water column (OWC)devices to generate electricity at the shore using the rise and fall of water within a cylindrical shaft. The rising water drives air out of the top of the shaft, powering an air­driven turbine. Third, a tapered channel, or overtoppingdevice
