A massage technique that gives the impression of waves hitting the body.
Undersea energy is also called ocean energy. Ocean energy refers to renewable energy related to seawater. The ocean receives, stores and emits energy through various physical processes. This energy comes in the form of tidal energy. and wave energy, temperature difference energy, salinity difference energy, ocean current energy and other forms exist in the ocean.
Ocean energy utilization refers to the use of certain methods and equipment to convert various ocean energies into electrical energy or other usable forms of energy. Since ocean energy has the advantage of being renewable and not polluting the environment, it constitutes a new source of energy of strategic importance that urgently needs to be developed.
1. The amount of ocean energy contained in the total ocean water mass is enormous, but the energy per unit volume, unit area and unit length is small. This means that if you want to get large amounts of energy, you need to get it from a large amount of seawater.
2. Ocean energy is renewable. Ocean energy comes from solar radiation and gravitation between celestial bodies. As long as the sun, moon and other celestial bodies coexist with the earth, this energy will be regenerated and will be inexhaustible.
3. Ocean energy can be divided into more stable and unstable energy sources. The most stable are the energy of temperature difference, the energy of salinity difference and the energy of ocean currents. Unstable energy is divided into two types: regular changes and irregular changes. Tidal energy and the energy of tidal currents aret unstable but change regularly.
Based on the changing laws of tidal currents, people compile daily and hourly forecasts of tides and currents for various locations to predict the size and strength of tides at different times in the future. Tidal power plants and tidal power plants can organize power generation operations based on forecast tables. What is both unstable and irregular is the energy of the waves.
4. Ocean energy is clean energy, which means that once developed it will have little impact on environmental pollution.
