If VASIMR is done, the obstacle to controllable nuclear fusion will be basically cleared, and Dongfang Sheng sees it this way.

Let's start with VASMR, where the original ion engine simply heated the gas to the plasma and discharged it through a grid. Not only is the kinetic energy of the ions emitted not high, but it is also blocked a lot by the grid, so the ion engine is completely ineffective.

The principle of VASIMR is to confine the ions that are initially heated into plasma in the magnetic field, further heat them with microwaves, and then rely on the deflection of the magnetic field to let the ions with sufficient kinetic energy escape by themselves.

But this process is not perfect, the heating rate of the plasma depends on the microwave frequency to synchronize with the ion resonance frequency, if the state of the plasma cannot be accurately calculated, this heating process will be relatively slow, and less plasma can be ejected per unit time.

When the fully heated plasma is detached from the magnetic field, the control of the magnetic field also requires a very precise control of the state of the plasma to ensure that the plasma with sufficient energy is effectively separated from the magnetic field. But in fact, there is still a large part of the ions that do not break away when they are at their best, wasting energy.

Combining the two aspects, Kunpeng's existing 20 MW VASIMR is at best 10% efficient, capable of generating 50 kilograms of thrust, and there is still a lot of room for improvement.

Theoretically, VASIMR can get more than 1 ton of thrust at 100 megawatts, and if the engine weight is controlled at 100 kg, this is a thrust-to-weight ratio of 10, which can be compared with the engine of a fighter jet.

Of course, such beautiful numbers are only on paper. For example, the energy system cannot be matched without black technology.

At present, the mainstream installed power of nuclear power plants is 1,000 megawatts, and the power supply power of the Ford-class nuclear-powered aircraft carrier in the United States is 200 megawatts, which is enough to solve the electricity consumption of a small city of 100,000 people and a space reactor of 100 megawatts.

In addition to energy, another difficulty goes beyond the scope of black technology, that is, the calculation of the state of plasma motion.

The motion of plasma is extremely complex, and it is impossible to calculate the trajectory of a single ion at a certain moment, but the motion of a group or even a small number of ions can still be estimated theoretically. And this estimation will require a super, no, super supercomputer to do it.

This calculation is related to controlled nuclear fusion.

Controlled Nuclear Fusion and VAMSIR are two branches of the same technology tree, of course, the former is a basic technology, and the latter is just a more detailed application branch, but they are both making a fuss about plasma.

To put it simply, controlled nuclear fusion is the burning of plasma to the point where it can trigger a nuclear fusion reaction and then convert it into electricity. VAMSIR also burns plasma, but when it burns almost enough, it is ejected to provide a reaction force. If you replace the nozzle with a focusing device and shoot the ions out as rays, it becomes a plasma cannon.

Controlled nuclear fusion simulates the high-temperature and high-pressure environment of the sun through the hundreds of millions of degrees of plasma, pressing two light atoms into one heavy atom and releasing huge energy. There are two main problems in this process, one is how to make the plasma have the conditions to produce nuclear fusion, that is, "ignition", and the other is how to continue to exist with hundreds of millions of degrees of plasma. After solving these two problems, it is possible to talk about converting the energy of the plasma to form a complete chain link.

According to the principle of confined plasma, the research of controlled nuclear fusion is mainly groping for two paths. Inertial confinement is the use of multiple lasers to irradiate fuel balls, and magnetic confinement is the same as VAMSIR, which uses a magnetic field to confine the plasma. However, controlled fusion requires a longer confinement time than the time required by VAMSIR.

Inertial confinement solves the "ignition" problem of nuclear fusion, but it does not solve the problem of containers for continuous reactions. The magnetic field confinement solves the container problem, but because the confinement time of the plasma is not long enough, it is difficult to achieve the condition of "ignition".

In contrast, the route of magnetic field confinement is more optimistic, but neither the tokamak route nor the stellar route can effectively extend the confinement time of the plasma, and then effectively ignite, because this requires more precise control of the plasma, and the premise of control is the accurate calculation of the plasma motion state.

"In this direction, the quantum physics theory and mathematical model we have mastered are like using Newtonian mechanics to solve quantum mechanical problems, and the deviation is too large."

Dongfang Sheng talked about the most critical point, Xia Ming asked: "That is, the problem of Planck's constant?" ”

"Yes, there is a benchmark for calculation, but the current constant can't cope with it at all," Dongfang Sheng said: "If there is a breakthrough in this area, coupled with the progress of materials and intelligent control, we can take the stellar simulator route and solve the two technologies of controlled nuclear fusion and VAMSIR in one fell swoop!" ”

Sure enough, it was a constant problem, Xia Ming groaned.

This problem should be solved in high-dimensional space-time, after all, the cosmological constant has a more complex embodiment in high-dimensional space-time, and it should be possible to break through by doing research there. But not only will it take a trip to Homo sapiens to make progress, but it will also have to pull in a theoretical physics team specializing in the cosmological constant, as well as a number of instruments, which will squeeze the observer position.

The kind of thinking logic cloud state that Xia Ming experienced in high-dimensional space-time, there seems to be something about the cosmic constant in the cloud. And the technology cloud carried by the core of Zhiyin, although there is no scientific theory, some creations are also related to constants.

"There are several places in the technology cloud of Zhiyin's core that are difficult to explain, and the most suspicious of them is this", Xia Xiaoyan projected something into his field of vision, Xia Ming looked at it for a while, and his heart was shocked.

Isn't this the rune pattern on the core of Zhiyin?

"I have a guess ......"

Xia Ming thinks, could this rune be something related to the cosmological constant?

There should be these things in the logic cloud, and he will understand it, but after exiting the high-dimensional space-time, the details will be blurred, and it seems that only in this case will the things he once understood be triggered.

Since it feels this way, then it must be like this. Xia Ming decided that after Qianyan rebuilt, the first thing he would do was to give this rune to Qianyan for analysis.

The plane began to land, and from the porthole, the fighters escorting the plane on the left and right were waving goodbye to the plane. On the left is Huaxia's J-16D, the Qilu aircraft carrier from Huaxia, and on the right is the F/A-18E, the USS Ford aircraft carrier from the United States.

Xia Ming now travels, on the high seas or in the air without state, and enjoys security treatment beyond that of the head of state. This is not what he asked, it is the result of the mutual distrust of the five hooligans, especially China and the United States.

Xia Ming asked the captain to convey his thanks to the escort fighters, and then looked down at the coastline below, thinking, Madagascar, I'm here again.

"Antsiranana welcomes you with the utmost enthusiasm, Natsu-chan!"

Albert put on the most solemn guard of honor at the airport, and when he hugged him, his arm was also extra forceful.

Xia Ming said: "What I hope to get is the enthusiasm of the whole of Madagascar. ”

"Passion is not enough, what you need is loyalty", Albert is much more mature than he was two or three years ago: "Loyalty to a great scientist who is committed to the benefit and liberation of mankind." ”

Xia Ming stood in the car, like the head of state inspecting the guard of honor, waving to the people who greeted him with singing and dancing, from the airport to Albert's official residence, his hand was never put down, sour, his smile never disappeared, and he froze.

After dealing with Albert's subordinates and Antsiranana's dignitaries, Xia Ming rubbed his face and said, "I'm really not used to this battle, let's get straight to the point, are you ready?" ”

"Everything is in place, only the east wind is owed", Albert showed off a handful of Chinese, and then introduced the current situation.

For more than two years after Xia Ming's departure, Albert and his organization of lowly people followed Xia Ming's advice to not take the lead in politics and not participate in the political and military battles in the capital Antananarivo, but to concentrate on farming.

Farming was multifaceted, and politically, Albert pursued a harsh revolutionism, swept away aristocratic families like Radama and institutionalized the organization of the lowly. In this regard, he has ample ideological weapons from China. Militarily, he built up a lean professional corps and reorganized the local police into a credible reserve. Economically, he adopted a gentle approach to improvement, adapting measures to local conditions, and building basic industries that could meet daily needs.

In terms of social control, he rejected the populist line of the revolutionaries in the past, established the Antsiraana Management Committee with the lowly as the core, established the leadership of the lowly in French, and made the rule of law the core of social control.

During this time, Antsiranana, and indeed the entire Diyana district, was the best in Madagascar. It has also become a place for Malagasy people to take refuge in civil unrest, and foreign investors are gradually returning.

Throughout the process, Albert did not work alone, from propaganda and promotion to economic planning and social management, he knew how to use technology to solve problems. In particular, the use of GEI in economic and social management has made the rule of the lowly organizations in Antsiranana more and more stable and popular.

After Lin Cheng arrived in Madagascar, he helped Albert complete the information technology reform in many aspects such as social security, and also gave Albert the confidence to sit in the north and look south.

"In recent years, I have also put a lot of effort into political theory, and the 'Malagasy doctrine' I put forward is now not only the guiding ideology of the lowly, but also the program of many political parties and groups in the south. If Madagascar had an uninterrupted general election, I would have at least a 60 percent chance of being elected. ”

"But you also know that it's impossible to be undisturbed, and we don't want to continue playing the kind of electoral politics that we used to have. I am ready for a solution by force, our army already has ten infantry battalions, three artillery battalions, two tank battalions, two fighter squadrons, two small fleets, and the equipment, although poor, is of high quality. ”

"As long as we make a call, once we go south, there will be many areas in the south that will respond to us, and the rotten class who are still struggling in the mud of Antanari Livo will not be able to make any waves."

Hearing Albert say this confidently, Xia Ming asked, "Then what are you waiting for?" ”

"I ...... Still hesitating", Albert said: "Our country, starting with the kingdom of Merina, has not yet had a history of large-scale civil wars, and we will definitely defeat the enemy. But after defeating them head-on, what kind of chaos will become, how long it will take to calm down the chaos in the whole country, and how many people will die at that time, I don't know what kind of chaos will become. ”

Albert is not a revolutionary who came out of the melting pot of China after all......

Xia Ming thought so, but in this regard, he and Albert had the same idea.

"It's simple, on the one hand, launching a political offensive, taking up the name of righteousness, winning the support of the grassroots people, and breaking the morale of the opposing forces. On the other hand, use precise military operations to eradicate stubborn faction leaders. Turn a large-scale war into a small-scale special operation. ”

Albert listened to Xia Ming's suggestion very humbly, but he still raised a question: "The level of our army is not able to do such a precise thing......

"There are satellites in the sky, advisers on the ground, and high morale among your officers and soldiers, which is enough," Xia Ming also said with a red heart: "I need to establish a scientific research and aerospace base in Madagascar, and the situation in Madagascar will be calmed down as soon as possible, and I will do my best to help you." ”

"Speaking of which......"

Albert showed his patriotic side: "What exactly do you want? ”

Xia Ming said: "A piece of land with convenient transportation, no less than 100 square kilometers, and completely independent legal rights, yes, you can treat it as a concession." ”

"Words ...... the Concession"

Albert showed an embarrassed expression, and Xia Ming said again: "Hundreds of millions of dollars in rent every year, countless jobs, and corresponding supporting industries have driven the service industry of at least one million people in the surrounding area, which is the benefit." Of course, the downside is obvious, you Malagasy people can't look back on the colonial past, and you are very sensitive when it comes to foreigners buying land, let alone concessions. ”

He looked at the other party seriously: "As the future leader of the country, you should weigh it well." If you don't agree, I can understand. ”

"No, no, how could I disagree", Albert waved his hand repeatedly: "I was thinking, how to wrap this thing up...... Let the Malagasy people accept it willingly, so as not to leave any hidden dangers in the future, hidden dangers for both of us. ”

"That's right!" Albert thought of something, slapped his face and said, "If you are not a country, then it is not a concession." If you buy it in the name of an individual, it is too ostentatious, so why not rent it in the name of an international organization? Like the various nature conservation societies that have long-term leases in us, although the area is much larger, Malagasy people are used to it. ”

That's a good way, but what should I name this organization?

Xia Ming suddenly felt that for him, this was a bigger problem.

"Called...... Xia Ming and his seven friends. ”

Later, at the AR scene meeting, Xia Ming asked the question, Lin Cheng joked, and then he was thrown two flashbangs.

"I think it's better to incorporate Liu Ruru's People's Revolutionary Federation into an official organization, and with this name, it's loud enough!"

He Xinghui's current mentality seems to be a bit extreme, or the second in secondary school.

"To have a sense of beauty and history, I think it's better to call it seven...... No, the Mountain of the Eight Sages. ”

Liluo arrived in Yandu and was undergoing psychological rehabilitation, looking like this, she was clearly French, but she put up the black tea recipe of the British, and it would take a long time to return to normal.

"What's there to think about, the high-dimensional space-time office on Earth."

Xiaotang is joining in the fun, so she doesn't care what the name is.

"Homo sapiens tour!"

Xiao Huan reappeared, raising his hand and shouting with vitality.

It's a pity that Qianyan hasn't been built yet, otherwise Xia Ming really wants to hear what strange name Qianyan will take.

"For the time being, let's call it the Zhishen Star Gate Management Alliance, referred to as the Star Gate Alliance, or Star Alliance, we are the gatekeepers......"

After discussing for a long time, Xia Ming slapped the board. There is no need to mention the high-dimensional space-time for the time being. It was so high-profile before, in order to bring everyone together. When the forces are kneaded together, it's better to keep a low profile, and let everyone treat their group as gatekeepers first.

"Lao Hong and Pang's mother are going to die", Xiaotang pursed his lips and smiled: "Just now, Dada's mother was still complaining, saying that you just stewed the ribs, and you ran away." (To be continued.) )
