Recently, more and more attention is paid to renewable energy. Recently, green energy or renewable energy is increasingly beginning to squeeze traditional energy based on the combustion of fossil fuels: coal, oil, and so on. Basically, the development of renewable energy sources comes from wind energy and solar energy. However, as recent situations in Germany, the United States and others have shown, wind energy has its drawbacks.
This is, first of all, the instability of the power supply, as well as the difficulty of converting variable wind energy into direct alternating current for industrial use.
Solar energy also has its drawbacks. This is the need for large areas, the need for just such sunny areas and the cleaning of solar panels from snow, dust and other precipitation.
Today, there is a search for renewable energy sources in all directions, the most insignificant options are being considered, such as, for example, at the junction of fresh water, salt water, some kind of energy is released.
The paper considers a method of obtaining energy using the temperature difference between day and night. At any point in the world, the temperature is always higher during the day, and always lower at night. This so-called temperature drop can be from 3 to 12.15 and more degrees, for example, in Urengoy in winter it can reach 60 degrees. It’s the same on the planets: on the moon, especially on Mars. There, the temperature difference between day and night is about 60-80 degrees, since Mars has no atmosphere.
