Britain will use waves to generate electricity. Britain will deliver an advanced commercial wave generator to the northern coast of Portugal to generate electricity by using waves. A special-purpose ship transported large tubular structural equipment from the western island of Scotland to the northern coast of Portugal. The 8 million pound pelami Wave Power Generation Project will eventually generate 2.25 MW, enough for 65,438+0,500 households. There are three giant wave generators, and the first four orange tubular structures have been completed, waiting for transportation. However, due to strong winds and sea storms, the shipment scheduled for Monday was delayed. The 3330-ton Danish cargo ship was forced to dock for shelter from the wind and could not get close to the slideway of the wave generator. The ship has a special stabilizer, which can stand on the seabed with both feet extended during loading and unloading. The ship will also return to Scotland to transport two other wave generators. Ka messer, whose generator is located in anish, Luis Island, was selected as the manufacturer by the wave power generation plan, and will produce 12 sets of giant tubular structures. Messer said that this is not only a good opportunity for his company, but also a good opportunity for the whole island of Lewis. They said that they built the world's first commercial wave generator here. The company has 90 employees in Stoneway, which is a large number in the western islands, but what really matters is that it can maintain these jobs. However, the Scottish National Party criticized Britain for being too slow and handed over the first commercial wave power generation plan to Portugal. They are worried that Portugal will now start producing its own wave generators.
Waves can move in the sea of Wang Yang. In addition to the ebb and flow of tides, the wind and the sea will wrestle with each other to produce waves, and the waves contain a lot of power, including kinetic energy related to the moving speed and potential energy of the distance between the sea and the water level. When waves impact forward or cause airflow, these energies can be converted into electrical energy through wave energy devices. At present, the application of wave energy is still in the experimental stage, and there are no examples of large-scale application. Application of science and technology in wave power generation: ● When a cylindrical caisson is put into the sea, the water level in the caisson will fluctuate due to the beating of waves. ● The fluctuation of water level will make air enter and exit the top of caisson, and the airflow will drive the turbine to drive the generator to generate electricity. ● Some countries will connect wave power generation devices with windmills to obtain wave energy heh/hehweb/* * artpower/re/tc _ w/water. Waves contain kinetic energy and potential energy. Kinetic energy is related to the moving speed of water, while potential energy is a function of the distance between seawater and water level. When waves directly impact or cause airflow, wave energy devices can use generators or windmills to capture the energy of waves to drive turbines to generate electricity. The energy of Energyland.emsd/text/chi/energy/renew_wave's wave comes from wind, and the energy of wind changes with the change of wind speed. Because wind energy also comes from solar energy, wave energy basically comes from solar energy indirectly. Wave energy must be extracted from the ocean and then transported to the shore for land use. Wave energy is generally used for power generation and has the following advantages: 1. Infinite resources: The ocean accounts for seven tenths of the earth's surface area, so there is no need to spend money on energy; 2. Reliable energy: not affected by national conditions and wars; 3. Reliable power supply: 24-hour continuous power supply, not afraid of insufficient raw materials; 4. Clean energy: no environmental pollution; 5. The site is easy to find: there is no land problem; 6. Simple operation: only a few people are needed to operate. Although wave energy has the above advantages, the utilization technology of wave energy is still in the research and development stage, and there is no commercial wave energy power plant except for small-scale application. Therefore, the power generation efficiency of wave energy is still uncertain. According to general estimation, the efficiency of commercial wave power plants in the future will be between 10 ~ 80%. At present, the main countries actively engaged in the development of wave energy are Britain, Japan, Norway and the United States. Anyone who has been swimming at the seaside must know that the waves are very powerful. Sometimes, sunbathing on the beach, the waves hitting the coast can not only push people down, but even pull them away; Or go out to sea in a rubber boat. When big waves come, rubber boats are often pushed very high, but then they will instantly sink to the bottom of the waves. It has been considered for a long time to make use of wave power generation's idea, but it was not until the last twenty years that human beings seriously considered its practicability. Because it can generate electricity without consuming fuel and will not cause air pollution, it has been paid more and more attention by countries. Japan was the first country to use wave power generation. 1964, the Japanese designed the 1 wave power generation buoy to indicate the voyage. This equipment generates little electricity. Later, I built the wave power generation ship, with a width of12m and a length of 80m. It can accommodate 1 1 generator, and the average power generation of each generator is 125KW. wais.ee.kuas.edu/energyworld/supplys/sea
Waves can interact with wind and sea surface to produce waves. Waves contain kinetic energy and potential energy. Kinetic energy is related to the moving speed of water, while potential energy is a function of the distance between seawater and water level. When waves directly impact or cause airflow, wave energy devices can use generators or windmills to capture wave energy, thus promoting turbine power generation. 2007-05-28 16:32:07 Supplement: Waves can be found in the sea of Wang Yang. Besides the ebb and flow of tides, the wind and the sea will wrestle with each other to set off waves, which contain a lot of power, including kinetic energy related to moving speed, water level and water level.
