After carefully flipping through the document in his hand, Xu Chuan placed it on the coffee table.
Opposite me, Academician Chang Huaxiang asked with a smile: "How do you feel?"
After thinking for a while, Xu Chuan said: "Theoretically, it is indeed feasible, but it is extremely difficult to build such a huge space carrier."
"Sending a giant circular object with a diameter of more than 500 meters into space at one time is impossible even with our current aerospace technology."
"A relatively reasonable approach is to transport it to space in sections and dock it in orbit. However, ensuring that large parts with large arcs can be docked accurately in space will be a severe test for technology, craftsmanship and operational experience.
"Even if this is the case, we can produce parts on earth, assemble them into semi-finished modules and launch them into space. I am afraid it will take at least 5-8 years, or even 10 years to do it."
"and....."
After a pause, he looked at the documents on the table, frowned slightly and continued: "In addition to the difficulty in design and construction, such a huge object is running in space."
"Even in low-Earth orbit, the space electrodynamic problems caused by the rotation of its outer ring structure cannot be ignored."
"This is the same as the 'space elevator' project we talked about before. The steel rope flying around the earth's magnetic field will also produce electromagnetic phenomena."
"Whether it is a steel cable or the outer ring structure of the space carrier, as a conductor, when flying in the earth's magnetic field at the first cosmic speed, cutting the magnetic field lines will produce a higher voltage, which is one of the potential dangers."
"On the other hand, from a physical point of view, this kind of large rotating spacecraft will inevitably encounter the problem of center of gravity shifting."
"To put it simply, when a large mass object moves in the pipe, it may be several people or heavy equipment, the entire space station will inevitably start to swing under the action of centrifugal force."
"This is also a big problem for the people who live in it and the equipment deployed."
"In addition, although the diameter of this space carrier is an astonishing 520 meters in design, its diameter is still too small for a gravity simulation device."
"This will cause the "gravity" of the human head and feet to be different, and the gravity gradient will produce a certain degree of dizziness."
"...These are foreseeable problems for this space carrier."
Although I am not a professional in the aerospace field, I have been developing new space shuttles for so long, and I have also come into contact with and learned a lot of professional knowledge in aerospace.
Although he is not as good as Academician Chang Huaxiang, he can still do it if he just gives some of his own ideas and suggestions on the design of this space carrier.
Of course, compared to professionals, his knowledge is nothing.
I believe that since the Aerospace Group has given a complete design plan for the space carrier, these issues he raised must have been considered.
Although it is said that it is nine stars difficult to build such a space carrier, with China's current economic strength and aerospace technology, this is not completely impossible.
But a 500-meter-long space carrier, even if it takes ten years, is completely worth it to the country as long as it can be manufactured.
An aerospace carrier that permanently cruises in outer space and low-Earth orbit will become another overlord after the aircraft carrier, replacing the aircraft carrier and becoming the protagonist of future wars.
Of course, with the current development speed of science and technology in various countries, in Xu Chuan's view, even if the construction of this space carrier is completed, it is more likely to carry out 'immigration', 'material transportation' and 'space development' between the earth and Mars.
'Wait for functions.
After all, no country except China can freely enter and exit space.
Although the United States has decades of leadership in aerospace technology, it has also restarted its space shuttle technology.
But really speaking, compared to their space shuttle, Lao Mi lags behind by more than a tiny bit.
The core foundation of the new space shuttle lies in the miniaturized controllable nuclear fusion reactor and aerospace engine.
As for the former, let alone miniaturization, even large-scale controllable nuclear fusion has not yet been achieved.
Not to mention the aerospace engine, which is an epoch-making product developed based on room-temperature superconducting materials.
If you pick any one of these two core basic conditions, it will be enough for Lao Mi to catch up for 20 to 30 years or even longer.
As for the space shuttle they restarted, the so-called "Endurance", in fact it is just continuing to rest on its laurels.
Not only are they resting on their laurels, but it can even be said that they have regressed a lot compared to their peak space shuttle technology in the last century.
You know, at the peak of the space race in the last century, the United States owned the Saturn V super-heavy rocket and seven large space shuttles.
Not only did it carry out many manned missions to the moon, it also accelerated the disintegration of Hongsu.
But now, the aerospace strength currently displayed by the United States is far inferior to what it used to be.
Even though SpaceX has held up the sky half a century later, using the BRF Falcon Heavy rocket to tell the world that they are still capable of sending astronauts to the moon.
But what everyone in the world sees is that the United States has long lost its dominant position and capabilities in the aerospace field.
Instead, it is China!
Today in the 21st century, they have not only achieved manned landing on the moon, but also built a huge outpost scientific research station base on the moon.
At the same time, China also led and promoted the world's largest outer space cooperation project, the Lunar Biosphere Project!
More than 30 countries around the world participated, with a total investment of 200 billion RMB!
If calculated based on the current exchange rate, its total investment has reached an astonishing 50 billion meters of gold.
However, today in 2025, in international trade, the most widely used transaction currency in various countries is no longer the rice dollar, but the RMB issued by them.
In the past, the foreign exchange reserves of rice dollars that countries have continuously reserved are gradually being replaced by RMB that they reserve.
Contrary to the dollar, the RMB currently has no anchor.
Or to put it another way, if the rice dollar is anchored to oil, then the RMB is anchored to China’s entire industrial chain industrial system.
They will not use force to maintain their currency status the way the United States uses rice dollars to harvest the world.
The most ideal thing is to use currency to anchor China's entire industry chain industrial system, use the reputation and stable strength of the world's factory, and have the RMB's ability to resist global financial risks as an endorsement, thereby enhancing the international reputation of the RMB.
status.
This is the safest and most trusted method.
To put it in layman's terms, the RMB anchoring method is that as long as you hold China's currency, you can buy any bulk product.
China's biggest advantage now and in the future is industry!
Huge industry, huge modern industry, information industry...as well as the intelligent industry that is currently developing, the smart industry and the future space industry, etc.
Only industry is the basic resource that truly supports the development of science and technology.
Lao Mi’s de-industrialization and the use of finance to control the world and play the game of beating the drum and passing flowers around are not stupid, but they just don’t have the ability to fight against it at the beginning.
I usually borrow money every day, but when the economy is bad, I will raise a wave of interest rates to make the rice dollars flow back, which will drive up the exchange rates of small and medium-sized countries, and then buy them at low prices.
This trick has been tried and tested over the past few decades.
And now, someone with the ability to break this pattern has emerged.
More importantly, this new model anchoring industrialization is still beneficial to everyone. So when the situation changes, countries will inevitably follow up quickly and change the currency. Why not?
For them, if the RMB flows to the world on a large scale and replaces the rice dollar as the mainstream trading currency, it will be beneficial and harmless.
When they become the currency of mainstream transactions, they will not only greatly enhance China's international influence in the world, but also reduce exchange rate risks and transaction costs, promote the optimization of economic structure, promote the development of the financial industry, etc., and the advantages are also full.

After chatting for a while about the Space Carrier, Academician Chang Huaxiang seemed to remember something, looked up and asked curiously.
"By the way, I remember you were studying electromagnetic shield technology before? What's the situation now? Is there any chance to apply it to this space carrier?"
Although he has been responsible for the work at Xia Shu Space Base, he still knows about the research and development of electromagnetic deflection shield technology.
Because this technology has been prepared for large-scale deep space navigation in Xu Chuan's design from the beginning, this is also something that Director Wu Yuankang of the Space Administration is more concerned about.
This time Director Wu came over and consulted him specifically about this area of work.
However, the departments responsible for research and development are not the Aerospace Research Institute and Xia Shu Base, but the other two departments of Xinghai Research Institute.
Of course, the Aerospace Research Institute is also involved, but the main force is still the group of people who originally studied controllable nuclear fusion technology.
After all, if you want to say which institution in the world is the best at controlling plasma and magnetic fields, it has to be the Xinghai Research Institute, which has solved the problem of high-temperature plasma turbulence.
Most of the personnel at the Aerospace Research Institute were later deployed or poached from other aerospace agencies, and have not done in-depth research in this area.
Even the aerospace engine, although nominally a project of the Aerospace Research Institute, was actually developed by the Energy Research Institute.
Hearing this question, Xu Chuan thought for a while and replied: "Part of it has been completed. There is a phased result, but there is still a long way to go before it can be applied to aircraft such as aerospace carriers."
"As for when it will be solved, no one can say. It depends on when the remaining plasma shield modules can achieve a breakthrough."
The magnetic polaron electromagnetic shield generator technology in the electromagnetic deflection shield has indeed made a big breakthrough. Through the application of magnetic polaron, explosive magnetic compression and other technologies, based on the polaron theory of the strong electric phonon interaction system and
The shield completed by the unified theory of strong electricity is already able to intercept high-power microwave attacks.
There is definitely value. Even if it is a phased result, its integrity is not bad and it has extremely high application value. It is impossible for other countries to do research and development at this stage.
He had previously heard from people at the Naval Equipment Department that they wanted to apply the magnetic polaron electromagnetic shield generator to the Hercynian aircraft carrier, but he gave up briefly later.
The reason is very simple, the communication problem cannot be solved.
If it is on the ground to generate electromagnetic shields to protect a scientific research institution or ground unit, they can also set up a communication network underground to transmit signals and information through wired methods.
But on mobile devices such as aircraft carriers and space carriers, wireless communication is the only way to communicate with the outside world.
The electromagnetic shield produced by the magnetic polaron electromagnetic shield generator shields the electromagnetic signal in all channels.
This means that when the shield is turned on, not only is it unable to be detected by the outside world through electromagnetic waves or high-power microwave attacks, but the equipment protected inside is also unable to transmit signals to the outside world.
This is a fatal flaw for aircraft carriers that need to carry carrier-based aircraft and serve as overseas mobile command centers.
After all, the times when the shield needs to be activated are often during wartime.
And if there is a lack of signals from aircraft carriers during the war, the consequences can be imagined.
It will be fun when the carrier-based aircraft cannot receive the guidance signal for takeoff and landing and plunges directly into the vast sea.
Therefore, the current fields of application of magnetic polaron and electromagnetic shield generators are still quite limited. When we can escape from using other wireless communication technologies other than 'electromagnetic waves', then the electromagnetic shield generator will be widely used.
the beginning of.
As for now, it’s just about protecting the ‘privacy’ buildings or equipment on the ground.
However, judging from the current situation, the above are very satisfied with the electromagnetic shield technology.
After electromagnetic waves are shielded, it means that unless the most primitive optical exploration equipment is used, other electromagnetic wave imaging systems will be in chaos when snooping into the protected area.
This technology is used to protect the confidentiality of some military secret areas and has initially achieved excellent results.
Academician Chang Huaxiang nodded and did not continue to ask further questions. He smiled and put away the report documents on the coffee table and spoke.
"Then let's get here first today. I will find a few trustworthy people at the Aerospace Research Institute and Xiashu Base to study this report plan for the space carrier."
"At that time, we will combine your opinions and ideas and submit them to the space agency."
Xu Chuan smiled and nodded, saying: "Then I'd like to trouble you, Chang Lao. The higher-ups have been trying to do this for a long time. We can help as much as we can."
Chang Huaxiang said cheerfully: "Well, don't worry, it's really going to happen, and it's good news for us."
Whether it is national defense strategic deterrence or the development of Mars, such a large space carrier has indeed many uses.
