Question 1: What are the new sources of marine energy such as salt difference energy, temperature difference energy, wave energy, tidal energy, ocean current energy and others?
Question 2: What are the new types of new energy sources? Different forms of energy come directly or indirectly from heat generated by the sun or deep within the earth. This includes energy produced from solar energy, wind energy, biomass energy, geothermal energy, nuclear fusion energy, hydropower and ocean energy, as well as biofuels and hydrogen derived from renewable energy sources. New energy can also be said to include various renewable energy and nuclear energy. Compared to traditional energy, new energies generally have the characteristicscharacteristics of less pollution and large reserves, which is of great importance in solving the serious problems of environmental pollution and resource depletion (especially fossil fuels) in today's world. At the same time, because many new energy sources are distributed equally, it is also of great importance in resolving energy-induced wars. According to the world's claims, resources such as oil and coal mines will decline at an accelerating rate. Nuclear power and solar power will soon become the main sources of energy. New energies
The United Nations Development Program (UNDP) divides new energies into three categories: large and medium hydropower; new renewable energies, including small hydroelectricity (Small-hydro), solar energy (Solar), and wind energy (Wind), Modern Biomass, Geothermal, Ocean (tidal energy);

> Question 5: What are the new sources of energy on earth? Solar Energy Solar energy generally refers to the radiant energy of sunlight. The main forms of solar energy utilization include photothermal conversion, photoelectric conversion and solar energy actination.Three main ways of scientific conversion
In a broad sense, solar energy is the source of many energies on earth, such as wind energy, chemical energy, potential energy of water and other forms of energy caused or converted by solar energy. The main methods of using solar energy include: solar cells, which convert the energy contained inconverts sunlight into electrical energy through photoelectric conversion, which uses the heat of sunlight to heat water and use the hot water to produce electricity; Solar energy can be divided into two types: 1. Photovoltaic solar panel module is a power generation device that generates direct current when exposed to sunlight. It is made of thin, solid photovoltaic cells that are made almost entirely of semiconductor materials (such as silicon). ). Since there are no moving parts, it can operate for a long time without any wear and tear. Simple photovoltaic cells can power watches and computers, while more complex photovoltaic systems can light homes and power the grid. Photovoltaic panel modules can take different shapes and the modules can be connected to generate more energy.electricity. In recent years, photovoltaic panel components have been used on roofs and building surfaces, and are even used in windows, skylights or protective devices. These photovoltaic installations are often called building-mounted photovoltaic systems. 2. Solar Thermal Energy Modern solar thermal energy technology bundles sunlight and uses its energy to produce hot water, steam and electricity. In addition to using appropriate technology to collect solar energy, buildings can also harness the sun's light and heat by incorporating appropriate features into their design, such as large south-facing windows or using materials from construction that slowly absorb and release heat from the sun. Nuclear energy Nuclear energy is the energy released by the nucleus of an atom in converweaving its mass, in accordance with Albert Einstein's equation E=mc^2;, where E=energy, m=mass and c=speed constant of light. There are three main forms of nuclear energy release: A. Nuclear fission energy So-called nuclear fission energy is the energy released by the fission of certain heavy atomic nuclei (such as uranium 235, uranium 238, plutonium 239, etc.). B. Nuclear fusion energy is composed of two reactions A in which one or more hydrogen nuclei (such as the hydrogen isotopes - deuterium and tritium) combine to form a heavier nucleus, and a loss of mass occurs at the same time to release huge energy is called a nuclear fusion reaction, and the energy released is called nuclear fusion energy. C. Nuclear Decay Nuclear decay is a much slower natural form of fission, difficult to use due to its slow release of energy.The main problems associated with the use of nuclear energy are: (1) Low resource utilization (2) Nuclear energy produced. after the reaction Waste has become a potential harmful factor for the biosphere and its final processing technology has not yet been completely resolved (3) Reactor...>>
Question 6: What energy sources are available in the ocean? Yes Oil, minerals (coal mines, gold mines and other metallic minerals)
Scientists have developed inexpensive and highly efficient technology. which uses solar energy to remove salt from seawater, making drinking water production safe. Although there is plenty of water on Earth, much of it is undrinkable seawater. Fresh water only makes up about 2.5% of the total. It's true, much of the world is experiencing severe water shortages.
In "AIP Progress" published by AIPPress, Chinese scientists reported the development of an efficient seawater desalination device powered by solar energy. The device includes a titanium-containing layer, known as TiNO, or titanium nitride oxide, which absorbs solar energy. The titanium oxide is deposited on a special paper and foam that allows the solar absorber to float on sea water.
When sunlight hits the titanium layer, it heats up and quickly vaporizes the water. By placing the device in a transparent container with a sloping quartz roof, water vapor can be condensed and collected to produce large quantities of fresh water.
“In the field of solar energy, TiNO is a common commercial solar energy-absorbing coating that is widely used in solar water heating systems and photovoltaic devices,” said the author Zhang Chao. “It has an absorption ratehigh solar energy and low thermal radiation rate, and can efficiently convert solar energy into thermal energy."
Researchers have developed a method to deposit a layer of TiNO using a technique called magnetron sputtering They used a special type of highly porous paper called Airlaid paper as an absorbent material powered by a seawater tank, made from wood fibers and commonly used in disposable diapers. evaporation device consists of three parts: the TiNO layer on top, the thermal insulation and the air cushion paper on the bottom. The insulation is made of polyethylene foam, which has many air-filled pores. which trap heat, allowing the multi-layer unit to float above a seawater tank, thereby minimizing heat loss to the environment. The porous air-cushioned paper used as a substrate for them. solar absorbersTiNO can be reused and recycled more than 30 times.
Salt precipitation on the TiNO surface could interfere with the effectiveness, but the researchers found that no salt layer formed on the surface, even after a long period of time. They believe that the porosity of the paper removes salt that might have formed on the surface and returns it to the seawater reservoir.
The salinity of ordinary seawater is above 75 000 milligrams of salt per liter. The salinity of ordinary drinking water is around 200 milligrams per liter. Desalination equipment can reduce the salinity of seawater to less than 2 milligrams per liter.
The combination of low cost, high efficiency and no clogging of this desalination technology suggests that it has the potential to help solve fresh water shortages around the world .
