Recently, my country's spacecraft announced that Chinese scientists have discovered a new mineral in Chang'e 5 lunar sample and named it "Chang'e stone". The English is called Changesite-(Y). The naming has been recognized internationally This is the 6th new lunar mineral of discovered by humans since landing on the moon.
What is Chang'e stone? What does it contain? I believe you must be curious in front of the screen. On September 11, 2022, a report by the British media "Business Insider" revealed the newly discovered lunar mineral "Chang'eshi" in my country, saying that the mineral contains helium-3 gas ( He-3).
Business Insider Report: Chang'eshi, a new mineral found in from lunar rock particles, is columnar crystal, similar to crystal, belongs to a phosphate mineral, which contains helium-3, which may become the energy for mankind in the future, so China therefore It is planned to carry out three unmanned moon landing missions in the next 10 years.
In fact, my country has long announced that Chang'e 5 sample contains ecstatic substance helium-3. The entire earth's helium-3 is only 500 kilograms, but the reserves of helium-3 on the moon exceed 1 million tons. Helium-3 was originally from Super solar wind . The moon is a high vacuum environment, and the loose lunar soil is easy to receive and store helium-3. Therefore, Chang'eshi minerals contain helium-3, which was expected.
What is helium-3? At present, human energy on the earth is mainly divided into two categories: one is traditional energy and the other is new energy. Coal, oil, natural gas belongs to traditional energy. Traditional energy can cause serious pollution to the air and the surrounding environment. It is considered the main culprit in the global warming of .
Wind energy, bioenergy, solar energy, hydropower, geothermal energy are all new energy. The biggest feature of new energy is that it will not cause pollution to the surrounding environment. It is called green energy. In fact, nuclear energy is also a green new energy. , because under normal circumstances, the use of nuclear energy will not contaminate the surrounding environment.
The country with the most nuclear power plants in the world is the United States. There are currently 99 nuclear power plants in operation and 5 nuclear power plants under construction, followed by France. France has 59 nuclear power plants in operation, second only to France is Japan. Currently, Japan is currently It has 57 nuclear power plants, more than my country's nuclear power plants.
At present, all nuclear power plants around the world use nuclear fission energy. Nuclear fission uses uranium-238, uranium-235, and plutonium as nuclear reactor material , and uses neutrons to impact uranium nucleus , making the nucleus split into multiple nuclei A nucleus with smaller mass releases two to three neutrons and and extremely large energy at the same time. The neutrons released by
hit other uranium nuclei, and the uranium nuclei split, releasing neutrons and energy at the same time. chain reaction continues until all uranium atomic reactions are over, but the nuclear power plant effectively controls the nuclear reactor Reaction speed so that it can slowly release energy.
"Nuclear Power" sounds high-end, but it is actually not satisfactory. In 2021, the total power generation of 99 nuclear power plants in the United States was 778.152 billion kWh, accounting for only 18.91%. The average power generation of each nuclear power plant is 7.86 billion kWh. my country's Three Gorges Power Station generates a total of 103.649 billion kilowatt-hours in 2021, which is equivalent to 13 nuclear power plants in the United States.
However, nuclear fusion can solve this problem. The nuclear fusion energy of the same mass is several times that of the nuclear fission energy . It is now 4 times, and it can reach 158 times in an ideal state. The nuclear fusion material is mainly the isotope of hydrogen deuterium and Tritium, multiple deuterium nuclei combine to form a nucleus with a larger mass, releasing huge energy and neutrons. The nuclear fusion technology used in
The most worrying thing about nuclear power is the "nuclear leakage". The former Soviet Union's Chernobyl accident and the Fukushima nuclear power plant accident in Japan are both chilling precedents. Once a nuclear leak, it will pollute hundreds or thousands of them. The area of square kilometers is because the nuclear material releases a large amount of microscopic particles streams, that is, nuclear radiation .
helium-3 is an ideal nuclear fusion material. When deuterium and tritium participate in the reaction, it does not release neutrons, no radiation, no energy, and only converts all energy into huge heat. 100 tons of helium-3 energy To meet human energy needs for one year, 1 million tons of helium-3 on the moon can meet 10,000 years of energy needs.
does not release neutrons and has no radiation. helium-3 is very safe to use and is a relatively safe future energy. The prospects are extremely promising, which also makes helium-3 valuable. Scientists evaluate it. Helium-3. It is worth about US$19 billion per ton, many times more expensive than gold. Whoever owns helium-3 first can master the future world.
Now "Chang'e Stone" contains helium-3. As for the content of helium-3, it remains to be further studied by Chinese scientists. In short, the helium-3 on the moon is the future energy that humans are salivating.
In the future, we can mine "Chang'eshi" ore on the moon, and then transport the ore back to the earth to refine helium-3, or directly extract helium-3 on the moon. my country's nuclear energy research institute also obtained a Chang'e 5 The lunar sample was studied to study the extraction technology of helium-3 and the nuclear reaction technology.
