Large-scale development of lunar surface resources requires a large amount of electricity supply. How to obtain sufficient and economic energy sources is a big problem. Fusion and fission reactions can generate a lot of energy, but building a nuclear reactor on the moon is expensive and interplanetary. Space resource development should tend to draw locally. Scientists at the Catalan Polytechnic University proposed heating Fresnel reflectors to heat the moon's weathered soil and generate gas to transfer energy to the Stra engines, which can generate large amounts of electricity.
According to foreign media reports, the moon is the closest natural satellite to the earth and the only satellite with a relatively large mass. Scientists have conceived a variety of scenarios for building an alien factory on the moon. Their purpose is to use the resources on the moon. Resources include large metal mineral resources, water resources and a large number of thermal energy resources. One of the sources of thermal energy is the light from the sun. The surface of the moon has only a very small amount of rare gas. It is similar to a vacuum environment. If a solar power station is built on the surface of the moon, a lot of solar energy can be obtained, but from the Polytechnic of Catalonia. University scientists also proposed a scheme that uses large reflectors and Stra engines to create a large moon power station.
This plan, also known as the mirror system, obtains energy by heating the surface of the lunar surface. The lunar surface can last for about 14 days at night, during which time the temperature can be reduced to minus 150 degrees Celsius if the lunar rover or lunar factory needs to To operate under such a low-temperature environment, it is necessary to use other energy sources such as nuclear power, etc. The lunar rover carried by China’s Chang’e 3 uses nuclear power, which is actually the energy released by the decay of isotopes.
The weathered layer on the lunar surface or lunar soil can be fully utilized to become a basic unit that can provide energy, and the energy source for heating is still solar energy, which means that the system can use solar energy to heat the weathered layer of soil and convert it into heat. To form electricity for use in lunar projects.
When the sun's rays hit the mirror surface, they acted on the weathered layer of the moon through the Fresnel mirror principle," said Ricardo Gangaresadescinka, a scientist in the study who believes this device can be used Electricity is generated in large quantities, and the gas generated by the heating system can be transferred to the Stirling engine to generate electricity.
Compared to traditional solar panels, they generate more electricity. Using the weathered soil on the moon, the electricity generated can be stored for 14 days of long lunar nights. If mankind chooses to build settlements on the moon in the future, manned missions must use a lot of energy. This is different from the orbital environment of the International Space Station and cannot fully provide enough power through the deployment of solar panels.
