Chapter 467 Chasing the Moon
China is soaring, and Shenzhou is reaching for the sky, traveling into space with the great aspirations and passion of the nation. Together, we raise our glasses to the moon and ask the sky, inspiring generations of Chinese people who have dreams of space travel.
From ancient myths, the Chinese dream of reaching for the moon has always run through the entire 5,000 years of Chinese civilization.
The Dunhuang rock paintings on the Silk Road in the Western Regions give the Chinese people the best interpretation of the dream of flying. The romance of mythology has created the eternal legend of Chang'e flying to the moon. People miss the fairy in Guanghan Palace and look at the Moon Palace from space. They have been searching for the dream of flying for thousands of years.
Since the founding of the People's Republic of China, China's aerospace engineering has been pursued since its inception.
It has been more than 60 years since the founding of the People's Republic of China. They have experienced many ups and downs along the way. However, from the beginning to the end, the dream of a rich and strong country, the dream of flying into space that has run through the entire history of New China... has indeed never stopped and has never left the land under their feet.
"Dongfanghong"; "Two Bombs and One Satellite" project; "Long March" series of launch vehicles... all were enthusiastically lit on this fertile land. The older generation left them and went west, Mr. Deng, Mr. Qian... but their energy will live forever with the country, and the aerospace industry has not stopped at this moment, but is moving towards the vast space.
Overseas countries have already taken a step ahead, and their aircraft have even been chasing Mars and Saturn. China is not discouraged and is always bravely chasing! Wu Tong smiled deeply, she loves her country, loves her iron will and her majestic spirit! Respect those predecessors who have fought for the country and contributed to the country.
Now, she inherited the wishes of her predecessors, Wu Tong solemnly stated:
"At this stage, we should proceed step by step. In this silent competition, I suggest that China can first enhance our influence over the Earth and the Moon. The first step is to try to build our own Guanghan Palace! From controlling the Earth and the Moon to the imagination of more distant star systems and the Milky Way! We should proceed step by step!
As you know, controlled fusion technology now has the basis for commercialization, but the fuel used in controlled fusion is deuterium and tritium. We have only solved the problem of tritium self-sustainability. However, no matter how high the self-sustainability efficiency is, the loss of tritium is still inevitable.
The first generation of controlled nuclear fusion technology can only be said to be a preliminary success. If we want to reduce the loss of reactor materials and release more energy, there has always been a further cognitive point of view in the academic community. The best prediction is to use deuterium and helium-3 as reactants to carry out fusion reactions.
Since electrons are produced instead of neutrons when D and helium-3 fuse, helium-3 fusion is also generally regarded as the most ideal fuel for second-generation fusion! "
Wu Tong quickly pulled out a piece of draft paper and a pen and quickly wrote down a series of data.
According to relevant data, the total annual power generation across the sea using helium-3 nuclear fusion power generation only needs 25 tons of helium-3; the total annual power generation in China in 1992 only needs 8 tons of helium-3, and 100 tons of helium-3 are enough for the world in a year. Based on the global electricity price and space transportation cost, the value of 1 ton of helium-3 is about 4 billion US dollars, and with the development of space technology, the space transportation cost will definitely drop significantly.
Although the cost of generating electricity through the deuterium-tritium reaction is already cheap and clean enough, they will most likely not be troubled by energy crises for hundreds of years to come.
However, compared to the thermonuclear fusion device that they have mastered, which uses the reaction of deuterium and tritium, using helium-3 for nuclear fusion reaction has more advantages than using tritium as fuel! First of all, the reaction produces more energy and consumes less energy, which is the most critical point!
Second, in the traditional tritium nuclear reaction process, along with the generation of nuclear fusion energy, a large number of high-energy neutrons are produced, and these neutrons can cause extensive radioactive damage to the nuclear reaction device; on the contrary, if helium-3 is used as a reactant, it mainly produces high-energy protons rather than neutrons, which is more beneficial to environmental protection; third, tritium itself is radioactive, while helium-3 is not.
Of course, if helium-3 is really used as fuel, there are technical barriers. The more charge the nucleus carries, the greater the Coulomb repulsion, and the greater the kinetic energy required for the atomic nuclei to approach each other, that is, the smaller the reaction cross section.
According to theoretical calculations, the cross section of the deuterium-tritium fusion reaction is dozens of times that of the deuterium-helium 3 fusion reaction. This means that in order to achieve the Lawson criterion for the fusion reaction, for helium-3 fusion, this data means that they need materials that can withstand temperatures of billions of degrees.
With the existing technology, it is obviously not possible to use helium-3 as the fuel for fusion reactors. However, things are in the hands of man, and they must first determine the location for future layout. The earth has only a mere ton of helium-3 reserves, and the real rich resources are on the moon that they look up to and has been passed down since ancient times, representing countless hopes.
There are rich reserves of helium-3 there. Although it may not be possible to utilize them in the near future, this does not affect the situation. It is a strategic resource that they must plan and master in advance!
From the ancient but passionate wish that the people have loved for thousands of years, looking for the moon, longing for the moon, and gazing at the moon... countless Chinese people have followed this wish for thousands of years.
The Weaver Girl and the Cowherd left many beautiful legends in the sky, but the symbol of the Big Dipper is the character of the Si Nan.
A noble country, standing on the Great Wall and looking at the horizon, looking down at the Great Wall from the horizon is so magnificent. Watching the rising sun, covered with a thousand-foot-high glow; looking down at the Yangtze River, the Yellow River, the Three Mountains and Five Peaks, and the blue planet. China asks the sky with Shenzhou, asking about the vast horizon; asking about the world's dream of flying; asking about the domestic scientific dream; asking about the great rejuvenation of China!
Wu Tong's eyes were burning at this moment. She had the courage to continue the great rejuvenation dream of her ancestors and pursue space exploration and moon landing. It all depended on whether she could launch a manned moon landing program and build an orbital space station!
"Okay, Mr. Wu, I will report your suggestions to my superiors truthfully! If you don't plan for the future, you will have immediate worries. Your foresight and planning for the future are things we must consider first!" Chu Hengyuan is very sensitive. Wu Tong only mentioned it briefly, but he has already realized a lot.
Although they are the first to successfully master controlled nuclear fusion, the world has already known which path Mr. Wu has taken to succeed. With the feasible technical routes and solutions already clear, the next country to master controlled fusion technology will emerge within 10 to 20 years at the latest.
This is not the ancient times when information was blocked. No matter how good the protection is, in the information age, no technology can keep secrets forever.
