There does not appear to be a necessary link between conductivity and the possibility of using it for electricity production. Simply put, as long as there is something that can make the coil move, it can produce electricity. Methods of generating electricity include hydropower. thermal, nuclear, wind, etc. wait. Conductivity can be understood as the directional movement of charged particles, provided that there are charged particles.
River water can produce electricity, and sea water can also produce electricity.
Use the tides to produce electricity. Tidal power plants and hydroelectric power plants on rivers are based on the same principle. People build a dam in an estuary or bay near the sea and install a hydroelectric generator in the middle of the dam. At high tide, the tide flows from the ocean through the dam justhan at the estuary or bay, driving the turbogenerator to produce electricity; At low tide, when seawater returns to the ocean, it drives the turbine in the opposite direction again. produce electricity. This type of tidal power plant generates more stable energy than hydroelectric plants built on rivers because it is not affected by floods and droughts.
There are three-foot waves on the windless sea. Waves are also a kind of energy, but converting wave energy into electrical energy is much more difficult than generating hydroelectricity. In the 1970s, Japan developed the first wave power generation device. There is also a generator of this type installed on a barge in the United Kingdom.
By using the temperature difference between the surface and deep layers of seawater, electricity can also be generated. This type of power generation device is similar to a thermal power plant: water vapor drives a steam turbine, and the steam turbine drives a generator to produce electricity. The high temperature of the surface seawater serves as a heat source for the steam engine, while the low-temperature deep seawater serves as a cold source to cool the waste steam. The United States has built an experimental seawater temperature difference power plant near Hawaii. Using a temperature difference of 20°C, 50 kilowatts of electricity are generated.
