Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter (WEC). Waves are generated primarily by wind passing over the sea's surface and also by tidal forces, temperature variations, and other ...
In 2010, Pelamis Wave Power began tests of the first Pelamis P2 machine, again at the EMEC Billia Croo wave test site. The machine was owned by the German utility company, E.ON, and was the UK's first commercial supply contract in the marine energy sector. [10] The P2-001 machine was named Vágr Atferð, Old Norse for Wave Power. [11]
From 2009 to 2011, Ocean Power Technologies ocean-tested its wave power generation system at the US Marine Corps Base Hawaii (MCBH) at Kaneohe Bay.The Oahu system was launched under the Company's program with the US Navy for ocean testing and demonstration of such systems, including connection to the Oahu grid.
The power of the ocean could soon be used to power homes in the U.S. as scientists prepare to test an untapped form of renewable energy. The U.S. Department of Energy has invested $112.5 million ...
Agucadoura Wave Farm in Portugal. The following page lists most power stations that run on wave power, however there are not many operational at present as wave energy is still a nascent technology. A longer list of proposed and prototype wave power devices is given on List of wave power projects.
Since the wave power in the equatorial region where this device was tested was low about 13 kW/m, the choice was for a multi-functional breakwater unit that could provide a safe harbor for fishing vessels and produce power more economically by sharing the costs of the structure. Electric power pumped to the grid was demonstrated. [26]
Breakwaters are man made walls (built offshore) which block the coastline from wave activity (often used around harbors). [9] Each turbine has its own collecting chamber and the chambers measure 4.5m wide, 3.1m deep and 10m high. This was the first instance of multiple turbines being used in one plant. [10]
Salter's duck, also known as the nodding duck or by its official name the Edinburgh duck, is a device that converts wave power into electricity. The wave impact induces rotation of gyroscopes located inside a pear-shaped "duck", and an electrical generator converts this rotation into electricity with an overall efficiency of up to 90%.
