Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, 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 factors.
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]
Oscillating water columns (OWCs) are a type of wave energy converter [1] that harness energy from the oscillation of the seawater inside a chamber or hollow caused by the action of waves. OWCs have shown promise as a renewable energy source with low environmental impact.
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.
Marine energy includes wave power, which is derived from surface waves, and tidal power, which is obtained from the kinetic energy of moving water. Offshore wind power , however, is not considered marine energy because it is generated from wind , even if the wind turbines are located over water.
9 December 2011, Fortum and Seabased sign an agreement to jointly construct a wave power station in Sotenäs, Sweden. Seabased agreed to manufacture buoys, generators, substations and converters at a factory to be built in Lysekil. Fortum announced the power station would produce 10 MW by 2015, using 420 buoys. [5]
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.
A number of Wikipedia articles contain pro and con lists: lists of arguments for and against some particular contention or position.These take several forms, including lists of advantages and disadvantages of a technology; pros and cons of a proposal which may be as technical as Wi-Fi or otherwise; and lists of criticisms and defenses of a political position or other view (such as socialism or ...
