What is new marine energy?

Ocean energy is a renewable energy generated during the movement of sea water, which mainly includes temperature difference energy, tidal energy, wave energy, tidal energy, l energy of ocean currents, energy of salinity difference, etc. Tidal energy and current energy come from the gravity of the moon, sun and other planets, and other ocean energies come from solar radiation. The temperature difference energy of sea water is a kind of thermal energy. The sea surface water temperature at low latitudes is higher, forming a temperature difference with deep water, which can produce heat exchange. Its energy is proportional to the temperature difference and the quantity of heat exchange water. Tidal energy, tidal current energy, ocean current energy and wave energy are toutes of mechanical energy. Tidal energy is proportional to tidal amplitude and tidal volume. The energy of a wave is proportional to the square of the height of the wave and the surface area of ​​the rippling water. There is still ocean energy in the estuary waters.

In the salinity difference energy of seawater (also known as the chemical energy of the 'sea water), there is a difference in salinity between fresh water runoff into the sea and salt water from the ocean if separated. Through a semi-permeable membrane, fresh water will flow to sea water. Penetration from one side can generate osmotic pressure, and its energy is proportional to the pressure difference and osmotic energy. The area of ​​the Earth is about 5.1 × 10^8 km^2, of which the land area is 1.49 × 10^8 km^2, or 29%; the ocean area is 3.61 × 10^8 km^2. At this level, the average altitudenne of all land is about 840 m, while the average depth of the ocean is 380 m and the volume of total sea water reaches 1.37 × 10^9 km^3. The sea without The end not only provides humans with navigation, water sources, and rich mineral deposits, but it also contains enormous energy. It stores solar energy and derived wind energy in the form of thermal energy, mechanical energy, etc. in sea water, unlike sea water. on land and in the air. Ocean energy has three distinctive characteristics: 1. It has large reserves and can be regenerated infinitely. 2. The energy flow is unevenly distributed and has a low density. 3. Energy is changeable and unstable.

Features

1. The amount of ocean energy contained in the total mass of ocean water 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 tidal current energy are unstable but change regularly. According to the changing laws of tidal currents, people make daily and hourly forecasts of tides and tides for various endstides 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 a clean energy source, which means that once developed it will have little impact on environmental pollution.
