As science and technology continue to update and times continue to evolve, people have discovered that some Earth resources can be used, such as solar energy, hydraulic power, tidal power, etc. People can use these resources to reduce their use of oil resources, so that the land can enter sustainable development and people do not have to face the problems caused by natural depletion. In recent years, people have built power plants under the sea, and the principles of electricity generation are as follows.
1. There is a lot of deep-sea magma in the deep sea.Although few people can access these areas at the bottom of many oceans, that doesn't mean humans can't use the resources there. Take the example of many volcanoes. Although the goodhuman sense thinks they are on the surface of the earth, there are actually many volcanoes at the bottom of many oceans, and these volcanoes contain very high molten magma. People can use the temperature it generates. to produce electricity. In this way, people can use these resources in various ways to help them reduce their overdependence on a certain resource, such as oil resources.
2. You can also use water flow to generate electricity in the sea.Secondly, we also need to know that in many ocean depths, water flows very quickly, and people used their imagination to think of building a power plant in the sea to use the water flowing in the sea. the moving generator to produce electricity. All of this is a design made by human beings based on human science.current and on the human imagination.
3. There is still plenty of flammable ice on the seabed that can be used by humans.Finally, there is another reason. There are many resources on the seabed that humans have not yet discovered. For example, people have discovered flammable ice on the seabed in recent years. This type of flammable ice burns with a much longer lasting thermal fusion ratio and at a higher temperature than the petroleum coal we know today. On the other hand, if this stuff is used to generate electricity, it will enrich the situation and allow people to use more resources.
The principle of a hydroelectric generator (water turbine) is that when water flows through the turbine, it converts the energy of the water into mechanical energy . The rotating shaft of the turbine drives the rotor. of the generator, which convertst mechanical energy into electrical energy and output.
The world's first hydroelectric power station was built in France in 1878. America's first hydroelectric power station was built in Wisconsin, United States, in 1882, using a direct current generator. After 1889, three-phase alternators began to be used. Since then, the capacity of a single machine has increased rapidly. In 1890, it was only 15,000 kW. By 1955, it could produce 105,000 kW generators. Before 1949, the capacity of a single unit of Chinese-made hydraulic generators did not exceed 200 kW. After 1949, the automobile industry developed vigorously. In 1958, it was able to produce a single 72,500 kW unit. In 1972, a double unit of 300,000 kW. -An internal water cooling water generator has been produced. The largest high-capacity hydroelectric generator in the world is the Grand Coulee Hydroelectric Generating Station, with a capacity of 718,000 km.VA stator water-cooled semi-umbrella hydroelectric generator, 737,000 kVA Itaipu Hydropower Station water-cooled semi-umbrella hydroelectric generator, umbrella hydroelectric generator air-cooled 700,000 kVA Guli hydropower station and 800,000 KW Xiangjiaba hydropower generator, etc.
