It's normal to develop some black technology in the future, right?

Chapter 420 Strange Silence
“Yes, radiation is of course going to be a major concern.

It's not just because the asteroid has radiation due to its orbit being changed by a nuclear bomb, the lunar surface itself also has radiation. After all, it doesn't have the atmosphere and magnetic field like the earth's surface to provide protection and shield most of all kinds of high-energy particles.

We will take protective measures to eliminate interference from various types of nuclear radiation particles, mainly using strong magnetic fields to shield high-energy particles, but gamma rays are an exception. Gamma rays are electromagnetic waves, they are not charged, and strong magnetic fields cannot shield gamma rays.

Gamma rays are still a kind of high-frequency electromagnetic wave with a very short wavelength and high frequency, so they have strong penetrating power and can easily cause damage to human tissue.

So in the final analysis, we still need space suits to provide protection for our astronauts.

In addition, robots will be used on a large scale in the early lunar bases.

If we extend the time dimension to 50 or 100 years, we will be able to transform the moon into an environment suitable for human survival.”

"Of course it is possible. Now astronauts need to wear thick space suits when they go to the moon because there is no atmosphere on the moon and they need space suits to provide protection.

But it is possible for us to transform the moon and create an atmosphere on it.

The moon's gravity is only one-sixth of the Earth's, so it has no way to maintain a long-term atmosphere. The huge temperature difference between day and night and the extreme environment caused by the collision of various celestial bodies make this difficult.

It is difficult to create an atmospheric environment similar to that of the Earth, but it is possible to give it a thin atmosphere. As long as we master the technology of controlled nuclear fusion, the large amount of helium-3 on the moon can be utilized.

The ice in the lunar soil can be electrolyzed into oxygen and hydrogen, the former used to build the lunar atmosphere and the latter used as fuel.

The transformation of the moon can also be seen as an early attempt at the transformation of Mars in the more distant future.

So if we extend the time dimension, it is very possible to do it.”

After Chen Yuanguang's interview with CCTV was broadcast, the issue that attracted the most attention from the outside world was the controlled nuclear fusion he mentioned.

This thing is too important. After the breakthrough in room-temperature superconducting technology, there have been rumors that controlled nuclear fusion is hopeful and will no longer take forever for fifty years.

But there has been no news since then. It has been almost three years since the breakthrough in room-temperature superconducting technology, and there is still no news about the breakthrough in controlled nuclear fusion technology. It is even worse than before the breakthrough in room-temperature superconducting technology. At that time, at least controlled nuclear fusion technology would come up every now and then to make its presence felt.

This has led to two rumors circulating in the market. One is that controlled nuclear fusion is too difficult, and room-temperature superconductivity is only one of the many technologies for controlled nuclear fusion. The other links have not yet been conquered, so there has been no progress.

This is not wrong, because in the final analysis, room-temperature superconductivity can only help controlled nuclear fusion solve the technical problems it is related to, such as stronger magnetic field confinement capability, higher energy conversion efficiency, more stable plasma, longer energy confinement time, etc.

However, the high temperature and radiation resistance of materials cannot be solved, because the high temperature plasma produced by nuclear fusion reactions is as high as hundreds of millions of degrees Celsius, which places extremely high demands on the high temperature resistance of device materials. Room-temperature superconducting materials can only solve part of the low-temperature cooling problem, but in the face of direct radiation and heat conduction of plasma, the inner wall of the device and other components still need to be able to withstand extremely high temperatures. Currently, no material can work stably and for a long time under such extreme high temperatures.

In addition, nuclear fusion reactions will produce a large number of high-energy neutrons, which will interact with the device materials, causing changes in the structure and properties of the materials. The long-term resistance of materials to neutron radiation damage is also a problem.

The second rumor is that thanks to the breakthrough in room-temperature superconducting technology, China has made a great breakthrough in controlled nuclear fusion. In order not to stimulate other countries, it has made a fortune quietly, so no publicity can be seen in the news.

This time, Chen Yuanguang took the initiative to mention controlled nuclear fusion in an interview, which caused an uproar.

The possibility of the second rumor is increasing.

"Laxative, I've been busy in the lab recently. I can only say that there will be progress by the end of this year. If there is no progress, I will bring my head to you. Just listen to the dragon's roar and that's it~
Okay, no more jokes, does room-temperature superconductivity help the development of controlled nuclear fusion? Of course it does, the original progress may have been stuck at 10%, 0.10.1 progress.

With the advent of room-temperature superconductivity, the rate jumps directly to 30% or even more.

But this does not mean that room-temperature superconductivity is a panacea that can help you solve all problems. You still have 70 progress bars. Even if the God of Light is really a god and can greatly reduce this time, it will not be done in three years. Do you think that playing Civilization VI, you can climb all the technology trees in one night?

Even with the God of Light, it would take at least ten years, but compared to fifty years, at least ten years is no longer a technological explosion that we won’t see in our lifetime. I really envy the next generation, they can just wait to enjoy the good life when they are born.”

"Controlled nuclear fusion is a highly confidential and professional field. It is really difficult to judge the current research progress. I can only analyze it from my perspective.
In America, MIT in California has achieved a net energy gain in nuclear fusion by using the inertial confinement approach, meaning that for the first time the energy produced by the fusion reaction exceeds the energy input to control the reaction.

They mainly manufactured superconducting magnets with a field strength of 20 Tesla. Precisely because MIT had previously gone the furthest in the inertial confinement route, they particularly hoped to obtain China's room-temperature superconducting technology.

After all, Nuno Loureiro, director of MIT's Plasma Science and Fusion Center, publicly stated in an interview with Science magazine that if China could make its room-temperature superconducting technology public, MIT would be able to develop controlled nuclear fusion technology within five years. Considering that the purpose was to create public pressure on China at the time, this time was exaggerated. But even so, I also believe that if MIT has room-temperature superconductivity, it is indeed not far from a technological breakthrough.

After China's rejection, Nuno seemed to have made a special trip to Yanjing. The general idea was that you provide the materials, MIT will be responsible for research and development, and adopt a joint research and development approach to advance the inertial confinement route of controlled nuclear fusion. The research and development results will be shared by both parties. I heard that the Chinese people did not like this plan in the end.

Based on this reality, I believe that China's research and development in controlled nuclear fusion is going more smoothly than the outside world expected, so they chose Duan Ran and rejected MIT.

Previously, China adopted the all-superconducting tokamak device, which mainly uses a strong magnetic field to confine charged particles, forming a circular magnetic field similar to a magnetic cage to confine deuterium and tritium gas in it, and then generates a huge spiral magnetic field by turning on the power, so that the plasma is heated to hundreds of millions of degrees Celsius in the magnetic field, thereby achieving fusion reaction. The all-superconducting tokamak device, just by hearing the name, you should be able to imagine how far this technical route can be advanced thanks to the breakthrough of room-temperature superconducting technology, right?
American's inertial confinement uses ultra-high intensity lasers to irradiate a tiny target pellet containing deuterium and tritium in a very short time. The high temperature and high pressure generated by the laser will compress and ionize the material inward, instantly forming a high-temperature and high-density plasma. By utilizing the inertia of the plasma itself, nuclear fusion occurs within a nanosecond time scale before it has time to scatter around.

In other words, the duration of such nuclear fusion is very short, but China was able to achieve 403 seconds of steady-state confinement before the breakthrough in room-temperature superconducting technology, and the discharge time has been able to exceed 1000 seconds.

Guangshen also mentioned strong magnetic fields in his interview this time. I have reason to suspect that China's controlled nuclear fusion can already achieve longer discharges and achieve effects similar to those of America, that is, the energy required to construct a strong magnetic field is less than the energy generated by nuclear fusion discharge.

I even suspect that China's controlled nuclear fusion has been initially completed, and now the newly built tokamak device can operate stably for a long time and discharge externally.

It is very likely that the dilemma facing China now is no longer controlled nuclear fusion, but the commercialization of controlled nuclear fusion.

One is how to increase the actual usable amount of electricity generated by its discharge, and the other is safety.

A company in Shenhai has previously made a fully high-temperature superconducting tokamak device called Honghuang 70. Why is it called Honghuang? It is said that they hope that the Chinese people can use the Honghuang power from controlled nuclear fusion as soon as possible. Their discharge cannot even reach the level that can be actually used.

So I think the Light God’s announcement means that a big breakthrough has been achieved, and the only thing left is how to implement the technology.”

The answers on Zhihu are considered rational. On Weibo, it is directly stated that China has achieved a breakthrough in room-temperature superconducting technology.

All the major stock forums are going crazy, all vying for the title of superconducting concept stock.

Shenhai Electric has been on the board for two consecutive days and has been hyped as the first stock in the room-temperature superconductor concept.

Read the error-free version at 69shuba! 6=9+shu_ba is the first to publish this novel.

There is no way, because Shenhai Electric is located in Shenhai, in the same city as Guangjia Aerospace. When Honghuang 70 was built before, Shenhai Electric was the core supplier of the device and was responsible for the manufacture of three core components: external vacuum dewar, vacuum chamber and internal and external cold screens.

Others like China National Nuclear Corporation and China General Nuclear Power Corporation, although they are professional companies in the field of nuclear power and have been operating nuclear power plants for many years, these companies have nothing to do with nuclear fusion in public information.

Shenhai Electric is a company that has truly done nuclear fusion.

"Guess how many consecutive boards we can get this time?"

"It has been at least five consecutive days. Shenhai Electric is not just winning by doing nothing."

"No, what they need to do is to find the leaders of Shenhai and securely take over the nuclear fusion business. Isn't this a ten-fold increase in stock?"

"Shenhai Electric is definitely the leader in controlled nuclear fusion this time. It is another A-share stock with a hundred-fold return. There is a lot of room for imagination."

"Are you crazy? It's fine if you say it will increase tenfold. The current market value is 100 billion, and 10 times is only 1 trillion. It is indeed possible if it can really undertake the nuclear fusion business. But it can increase a hundred times, which means it has to have a market value of 10 trillion. This is Shenhai Electric, not Guangjia Electric."

"What's wrong with 10 trillion? If it's really a controlled nuclear fusion business, is 10 trillion an exaggeration? The Americans were able to drive Nvidia's market value to 4 trillion US dollars based on the concept of AI. If we can achieve controlled nuclear fusion, 10 trillion RMB is not an exaggeration at all."

The guy in the stock forum is like he took stimulants, and it's even more so because he has positions in Shenhai Electric. It's simply outrageous.

Even if China achieves controlled nuclear fusion, Shenhai Electric is still a long way from taking over the business. How can a local state-owned enterprise like Shenhai compete with central enterprises such as China National Nuclear Corporation and China General Nuclear Power Corporation?

However, this incident also fully demonstrates Chen Yuanguang's influence. The mere mention of controlled nuclear fusion can set off a wave of controlled nuclear fusion in China's stock market.

Back to the asteroid's orbit change, there is a very strange phenomenon, that is, Europe has the loudest condemnation. Countries you have heard of and countries you have not heard of are all condemning it and asking China not to do this. They are always mentioning the safety of the earth.

After the Fukushima nuclear accident, the EU restricted food imports from Japan-related prefectures and required pre-export testing of food for radioactivity. After the discharge of nuclear wastewater, the EU lifted restrictions on food imports from the Fukushima region of Japan.

Those who don’t know would think that Europe really cares about the earth.

Because in the era of collective right turn, the politicians who have come to power in European countries in recent years have become less and less concerned about environmental protection, and they treat the commitments made in the Paris Climate Agreement as waste paper. This is not what I agreed to, so new people, new ideas.

Of course, there were also loud protests from countries such as the Kangaroo Country, the Maple Leaf Country, and New Zealand, all of which expressed that China’s actions were ill-considered and irresponsible to the earth.

On the contrary, there was not much voice from America, and the White House only said that it would carefully monitor the possible impact of this incident.

Neither Japan nor Korea made any noise, and even no one in the public protested.

This is easy to understand. Neon and Goryeo are too close to each other and dare not talk to each other. No one wants to be hit by a nuclear bomb for no reason, especially Neon.
