Ocean Wave Energy
Catching A Wave
I read an article in the Smithsonian Magazine, which I love, that gave me hope for a cleaner and more efficient energy source. That source is wave energy. When you think about the ocean, its waves coming in and going out, over and over, it seems so practical and you wonder way it wasn't done long ago. Engineer van Jouanne says "patents have been around since 1799." That's a long time. Annette van Jouanne claims that the ocean's boundless energy could furnish up to 6.5 percent of U.S. electricity.
While surfing one day in 1995, Annette begin to think of the tremendous power that was in waves. What really hit home with her was the fact that wave energy is always there. It never stops. She felt that its energy could be harnessed efficiently and responsibly. And, the ocean apparatus that would generate kilowatts could be much smaller that those that are used to generate power from wind and solar. What needed to be considered was the power and destructive element that is capable of the ocean and some mechanism which would withstand its power. In doing so, it would need to remain harmless to the sea animals and its environment. She has developed a wave energy converter buoy. It contains coils inside an anchored column surrounded by a magnet attached to a float. Waves move the float up and down, and the electromagnetic interaction generates current.
Engineer van Jouanne has joined the forces of the Oregon State University and the Wallace Energy Systems and Renewables Facility (WESRF), or best known as "We Surf", also located in Oregon. She continues her research and dedication to ocean wave energy.

What is wave energy?
Wave energy is an irregular and oscillating low-frequency energy source that can be converted to a 60-Hertz frequency and can then be added to the electric utility grid. The energy in waves comes from the movement of the ocean and the changing heights and speed of the swells. Kinetic energy, the energy of motion, in waves is tremendous. An average 4-foot, 10-second wave striking a coast puts out more than 35,000 horsepower per mile of coast.
Waves get their energy from the wind. Wind comes from solar energy. Waves gather, store, and transmit this energy thousands of miles with little loss. As long as the sun shines, wave energy will never be depleted. It varies in intensity, but it is available twenty-four hours a day, 365 days a year.
Ocean wave energy technologies rely on the up-and-down motion of waves to generate electricity. The first wave-power patent was for a 1799 proposal by a Parisian named Monsieur Girard and his son to use direct mechanical action to drive pumps, saws, mills, or other heavy machinery. Installations have been built or are under construction in a number of countries, including Scotland, Portugal, Norway, the U.S.A., China, Japan, Australia and India.
Where are the best waves?
Generally, extreme latitudes and west coasts of continents. View global wave atlas (based on satellite data) and another world wave map
The world's first commercial wave energy plant, .5 MW, developed by WaveGen is located in Isle of Islay, Scotland.
Here is wave data from the National Data Buoy Center or the Army, or the Scripps West Coast wave data system. You can also try http://www.nodc.noaa.gov/General/wave.html or http://www.globalwavestatisticsonline.com/ for a fee. It has been estimated that the total available US wave energy resource is 23 GW- more than twice as much as Japan, and nearly five times as much as Great Britain.

- How Waves Are Made
Waves are generated by wind. Offshore storms generate winds which blow on the surface of the sea and create ripples - much in the same way as the ripples in your post surf cuppa are made when you blow on it to cool it down.

In 1909, ocean wave power was used to light lamps on the Huntington Beach
Wharf until a storm carried the apparatus out to sea.
