Who s contribution is this??? - please let me know - Horst

Wave energy is produced when electricity generators are placed on the surface of the ocean. The energy provided is most often used in desalination plants, power plants and    water pumps. Energy output is determined by wave height, wave speed, wavelength, and water density. To date there are only a handful of experimental wave generator plants in operation around the world. The articles on this page explore the world of wave energy and its possible applications.

- What is the effect on the environment?


Corrosion: Protection of metal constructions can be provided up to 30 years and more.

Pollutants: Wave energy companies use big volumes of hydraulic fluids, which may cause a leak of hydro fluid to the ocean.

Other benefits: Does not have any noise pollution, does not generate solid waste or wastewater, does not have any gaseous or CO2 emissions and is totally clean and pollution free.

Coast damage: It is big,so then spoils the landscape and the beach.

Oscillating water column is a type of energy generator with waves;The earliest use of Oscillating Water Columns was in whistling buoys. These buoys used the air pressure generated in the collecting chamber to power a PTO system. J. M. Courtney patented one of these whistling buoy designs. In 1885 Scientific American reported that 34 of the whistling buoys were operating of the coast of the USA. The next major innovation occurred in 1947 when Yoshio Masuda, a Japanese naval commander designed an OWC navigation buoy that used a turbine PTO system. OWC are devices that generate energy from the rise and fall of water caused by waves in the ocean. As water rises and falls around and inside an OWC, air is displaced by the water in a collecting chamber and pushed back and forth past a Power-Take-Off (PTO) system. The PTO system converts the airflow into energy.

Does it produce carbon dioxide?

Wave power

there are 3 types of machines that produces energy from waves. With the air pressure and with floating blocks and with tubes. I'am going to talk about the floating blocks.

You have 2 blocks they float on the waves, its smart because a wave always go from L-R or R-L so first the block on the R/L goes up than the other. It would be stupid if it only where floating blocks because than it would´t produce energy, so the putted poles at blocks that poles are than attached to a rad the rad is attached to dynamo the is the same that is on your bike but than a little bigger :-). the rad turns around because of the waves so there is no burning so its okay for the environment. https://www.google.es/search?q=wavepower&safe=active&client=ubuntu&hs=mqZ&channel=cs&source=lnms&tbm=isch&sa=X&ei=FGgqVOvCBfDd7QbDkoH4BA&ved=0CAgQ_AUoAQ&biw=1301&bih=682#facrc=_&imgdii=_&imgrc=U9G1IlJIxnhzwM%253A%3BmbN3l3bIy0FSrM%3Bhttp%253A%252F%252Fwww.designweneed.com%252Fwp-content%252Fuploads%252F2014%252F02%252FWave-energy-plants-700x525.gif%3Bhttp%253A%252F%252Fwww.designweneed.com%252Fwave-power-plant%252F%3B700%3B525

Comment of Ms. Doolaard

Please add a picture of how it works and discuss what you can see on this picture.

in europe we need lots of energy, for our phones, lights, televisions even cars. We get energy from some ores and other materials the earth has given us, but after 50 to 100 years we run out of ores. And what than? We found some other ways to get energy. With this ways we don´t need to use ores, and thats wat we want. wave power is one of that ways. with wave power we can get energy, and we need that, but is wave power a good way to get energy? Thats what we tried to find out during this project.

wave power has effect on the enviroment the rusted steel or metal makes the water dirty. Also the live enviroment of the fish gets destroyed and sometimes coral riffs. Also it can happen that the oil in the dynamo is leaking.But it doesn´t produce any gasses that make the air unhealthy

Comment of Ms. Doolaard

What about the poor fish and pollution of the horizon?

Where can you find wave power? - Northern Canada - southern africa - united kingdom - New Zealand - Australia - portugal The best wave energy environments are along western coastlines because the most consistent winds come from the west. There are limited wave power opportunities in the East. You can find wave power in the the United Kingdom, Portugal, Australia, New Zealand, Northern Canada and southern Africa. In portugal the project has started, but is spread out to a lot of countries

Please say this in your own words.

Conclusion: Things went well because everybody did their work and they didn´t argue about it. But things also didn´t went well because at first there were some people that didn´t know what they had to do, so that part was a little bit difficult. The first lesson was searching for information about wave power. The second lesson was much clearer because at the start of the lesson we discussed briefly who was going to do what.
