was on China's Chang'e 5, after successfully digging from the moon and returning to the earth, US President Trump signed a bill to fully promote the return to the moon plan. The United States will build a solar on the lunar surface in 2027. Power station. Countries all over the world will solve the problem of energy demand and focus on the moon. Many people are wondering, if solar power stations can be built on the surface of the moon, why not build solar power stations in the orbit of the earth? Isn't the distance closer?
Earth’s energy shortage is a major problem. According to data, there is less than 100 years of oil available for exploitation on the earth, and other mineral reserves are also shrinking. The world's industry is developing rapidly, and the demand for energy will become more urgent. Many local wars are due to competition. Caused by energy.
Solar energy is a clean energy, and it is also an inexhaustible green energy source. The development and utilization of solar energy by human beings will be the future development trend. In the geosynchronous orbit, mankind has built a number of large-scale international space stations , which serve as important sites for astronaut space activities. Theoretically speaking, the construction of solar power stations in the earth's orbit is completely possible.
At present, the transmission of electric energy in the form of wireless radio waves has made significant technological progress. The United States can even send electric energy back to the earth receiving station through radio waves on the surface of the moon. The wireless charging technology has been more perfect, including us All mobile phones used can be charged wirelessly. Advances in technology have been able to solve the problem of power transmission.
Why don’t humans build solar power stations in the orbit of the earth? Some people believe that the construction of solar power stations in the orbit of the earth, especially large-scale solar power stations, will block the sunlight from reaching the ground, affect the growth of ground plants, and also affect air flow and water cycle , or even Cause damage to the earth's ecology. This view of
does have a certain possibility, but for the vast universe, no matter how large a solar power station is built by mankind, in the huge range of space space, it will hardly affect the ground illumination problem, just like At present, the international space station and various satellites and other spacecraft built by humans are difficult to see with the naked eye on the ground, and it is even more unlikely that there is a problem of blocking sunlight.
Humans dare not build large-scale Dayang power stations in the orbit of the earth. The most important reason is that they cannot withstand the impact of space junk. A solar power station needs to occupy a large area. The larger the area of the solar power station, the greater the probability of being hit by space junk, and the later maintenance costs will be high.
According to the estimates of European Space Agency , the number of rocket wrecks, abandoned satellites and other spacecraft currently remaining in space is very large, with a total weight of more than 7,000 tons. Disposing of these space junk has become a very difficult problem. With the technology and capability, the space junk cannot be completely cleaned up, and the cost is relatively high. Processing 100 kilograms of space junk will cost 100 million Euros, which is currently impossible to achieve.
