To be honest, most of the three problems raised by Comrade Diao can be solved in Liu Feng's opinion.

Antimatter can already be manufactured on a large scale, and it is a matter of course to use it for power generation, and the problem of being able to use it in spacecraft to generate electricity and obtain energy lies in the miniaturization of the Penning ion trap device.

Naturally, it is indeed difficult to achieve the kind of miniaturization that the Penning ion trap device can be carried by an individual, in 2 or 30 years;

But shrinking a device the size of a small house to the point where a small truck can pull it away, if there was a bit of a problem before, is now...... After he advanced computational materials science to a new level, causing the country's materials research results to become a blowout, it was only a matter of one or two years.

As for the power of launch vehicles or spaceships, after having the most thrust of the antimatter engine, all this is just trivial.

Because the thrust-to-weight ratio of the antimatter engine can be completely done to the extent of a small horse-drawn cart.

If the launch weight of the most advanced "Energy" carrier rocket in the woolly bear country is 3,600 tons, but at most it is only about 40 tons, close to one-90th of the payload, then the spacecraft based on the antimatter engine can reach 36,000 tons or even 360,000 tons or more of the launch weight, and the payload can reach at least half of its launch weight!

More than 50%, not at all in the same order of magnitude!

Therefore, human beings can have enough supplies to sail in the starry sky of the universe, and no longer worry about supplies for 10, 20, or even a lifetime, and at that time, the interstellar era will naturally come.

And now, the scientific research team led by Academician Kim Donghan has already designed the drawings of the antimatter engine.

The reason why the prototype has not yet been produced is that on the one hand, it is too late, on the other hand, in fact, it is the same as the domestic aircraft engine, facing the same problem - the engine produced under laboratory conditions may be okay with use, but there is still a long way to go to achieve more practical and reliable large-scale production.

After all, whether it is a space engine or an automobile or aircraft engine, in fact, any research team can draw a design picture very sci-fi;

In the case of aircraft engines, what vector nozzles, high thrust, high thrust-to-weight ratio, etc., even Ah San's designers can design to break through the sky - punch F22, kick J20......

However, the reason why aircraft engines are called the pearls of the industries of a large country is not just about design;

Because no matter how beautiful the design drawings are, if there are no suitable materials, there is no ability to precision process these materials, even if the indicators are advanced and the cowhide is blown loudly, but it can't be produced, what is the point of not being able to make it?

Therefore, the design of the engine must also take into account the existing materials in China and whether there is such a precision manufacturing capacity, which Academician Jin Donghan and others have considered, but they have not yet begun to build it, and they cannot specifically point out what difficulties will be encountered.

However, with the successful test flight of J20 as an example, Liu Feng believes that with the power of the whole country, this kind of precision machining problem is the easiest to solve.

As for the last question, the biosphere system, it is even simpler.

In essence, it is only a matter of energy, and with antimatter as the basis of energy, the 'artificial sun' is not an unattainable dream, and it is not a matter of growing whatever you want at that time.

……

Regarding Comrade Diao's suspicions, Liu Feng patiently answered them.

After all, this guy also knows that whether his life in the future can be as nourishing as it is now, most of it will fall on this person.

Naturally, Comrade Diao listened to Liu Feng's opinions very carefully.

As for the elder on the side, although he was also very concerned about how Liu Feng answered, unlike Comrade Diao's continuous in-depth inquiries, the old man did not express any opinions throughout the whole process, just listened quietly to the conversation between the two and nodded from time to time.

In the end, the result of the dialogue - Liu Feng was not fully able to convince Comrade Diao.

After all, there is a specialization in the art industry, and a lot of knowledge is not something that this elder can understand.

But it was not without results.

Because Comrade Diao said that in the near future, he will organize a more formal, stricter, and more extensive scientific policy, and at that time, not only the antimatter engineering project team represented by Liu Feng, but also scientists in other fields, senior state officials, and high-ranking military officials will also attend.

And Liu Feng will also accept these people's stricter and trickier 'interrogation'!

……

This high-end dialogue is naturally something that no one dares to record.

However, in the memoirs of Comrade Diao in the future, this dialogue was evaluated as a landmark dialogue that would affect the national fortunes of China in the next few hundred years, and this was known to future generations!

'Politics' has finally come to an end.

As soon as Liu Feng walked out of the office, the Great Elder and Comrade Diao discussed it.

Great Elder: "What do you think of this young man?"

After a moment of silence, Comrade Diao responded:

"As the best scientist in China today, his scientific research results are not something that I can ignore, and I may not be able to understand it, but from the conversation just now, I can feel that he has his own principles, and he will not stand idly by because he may offend people, this kind of responsibility is precisely the most important quality that a scientist must have in order to be called a national treasure-level master, and I think he has such a quality. ”

Hearing Comrade Diao's evaluation of Liu Feng, the old man nodded with satisfaction.

……

The sky dawned, and the clouds rolled up.

After the continuous rain, the first rays of sunshine finally fell on the horizon of the capital.

Just like Liu Feng's mood now.

From the apprehension he felt when he first saw Comrade Diao to the present day, he already had confidence in his heart.

Obviously, this dialogue is a small event under the transfer of power of the Great Elder, but for Liu Feng, it is a major event related to the direction of his future life, to say the key point, and even related to the life and death of the entire antimatter project.

Although in the end, he was not able to completely convince the future Great Elder, from his attitude towards him, Liu Feng could completely see that he had passed the test.

As for whether Huaguo's weapons development process in the next few decades will run according to his suggestions, it is not up to him to decide, and Liu Feng only wants to have a clear conscience and do his best to convince the high-level.

So, after coming out of the Great Elder's office, Liu Feng then convened a meeting of the heads of the various sub-projects of the antimatter.

"Academician Tian, next, for the latest research on the Pengning ion trap project, we will temporarily change the direction. ”

After giving a detailed introduction to his plan for the future interstellar era to the responsible persons, Liu Feng first instructed Academician Tian Xuelin.

"Understood!"

Academician Tian nodded solemnly.

During this time, he has been researching the Penning ion trap device that can store more antimatter, from the previous 1mg~100mg, to the next 1g, 10g, and even 1kg, he has a very clear plan.

Therefore, for the Penning ion trap device, the volume and weight are not in his consideration at all, and of course it is developing in the direction of becoming larger and heavier.

And this time, since Liu Feng has set the tone, he wants to conduct miniaturization research on the Pengning ion trap device that can store 100mg of antimatter for the time being, and the ultimate goal is to be able to install it on the spacecraft, knowing the seriousness of this, he naturally responded very readily.

Liu Feng also nodded with satisfaction.

The cooperation between him and Academician Tian Xuelin has always been very pleasant, in addition to the rich academic knowledge of both of them, his own courage and Academician Tian's execution are also the lubricant for maintaining a good relationship between the two.

Liu Feng also believes that it is definitely the wisest choice to hand over the Pengning ion trap to Academician Tian to be responsible.

This is followed by a question about antimatter power generation projects.

Academician Qian Zhengying, who gave Liu Feng an answer.

"On how to convert the energy of antimatter annihilation into electrical energy, after a year of research, we have finally designed a plan, here, I bring a design sketch, and I also ask for more advice from academicians. ”

The old lady skillfully opened the PPT on the computer, and a design drawing was projected onto the screen through the projector in the conference room.

Obviously, in this drawing, the old lady borrowed some of the advantages of hydropower generators and thermal power generators, and finally combined the design ideas of high-temperature gas-cooled reactors for nuclear power generators.

The reason why most of the design ideas are similar to those of high-temperature gas-cooled reactors for nuclear reactors in the end is clear to Liu Feng.

The research and development of high-temperature gas-cooled reactors in China began in the mid-70s, and the main research unit was the Nuclear Research Institute of Mizuki University, and up to now, the research departments and teams have already branched out more than one, and China's high-temperature gas-cooled reactors have also developed to the fourth generation, becoming one of the few countries in the world that can process and manufacture key equipment for high-temperature gas-cooled reactors!

In addition, high-temperature gas-cooled reactors have good inherent safety, will not cause damage to the public in the event of an accident, can compete economically with other power generation methods, and also have the advantages of short construction period.

It can be manufactured independently, and the technology is advanced and mature, with many advantages, and the economic performance is also very good, so it has naturally become the primary reference object of antimatter power generation projects.

However, after a brief glance at the sketch, Liu Feng shook his head.

"It's rare for us to come up with such advanced technology, and it's a bit wasteful to continue to use the method of 'boiling water'. And, if we want to use it in the spacecraft of the future, where are we going to find so much water?"

Academician Qian: "First of all, we ruled out the idea of being able to use it on a spacecraft to generate electricity, after all, we have been considering the direction of using it for power generation projects on the earth, so we will arrange research on this set after the meeting; moreover, you can't deny that boiling water is still the most efficient way to generate electricity on the earth." ”

Liu Feng shook his head: "Well, we will talk about the future that can be used for spacecraft power generation, and as for the question of whether boiling water is the most efficient to generate electricity on the earth, I don't think it maybe!"

Academician Qian did not speak, but waited for Liu Feng to continue.

However, Liu Feng did not give any explanation, just took a piece of A4 paper and spread it on the table, then picked up the signature pen and drew a sketch on it.

As he has been exposed to more and more engineering projects, such as the construction of the super collider he is responsible for, the comprehensive power system engineering of Academician Ma Mingwei of the Naval University of Engineering, and the construction of electromagnetic guns and electromagnetic catapults, etc., he has accumulated enough practical experience in addition to brushing up on the level of engineering.

With his current attainments in engineering, ordinary academicians of the Academy of Engineering may not be able to compare with him, otherwise, Academician Ma Mingwei would not have admired him so much.

And in engineering, drawing is only the most basic ability.

At this moment, the signature pen in Liu Feng's hand seems to be dancing, even if he strokes casually, it is as standard and beautiful as a ruler and a drawing.

Looking at Liu Feng's drawing movements, Academician Qian narrowed his eyes, and a look of surprise flashed in his pupils.

If she remembers correctly, this Professor Liu will not be 20 years old until June of a few years, and it is absolutely impossible to do this skillful strokes without three or five years of experience;

What a wickedness!

Liu Feng naturally didn't know about Academician Qian's exclamation, he just focused on the drawing work in his hand wholeheartedly.

First, the outline of the Penning ion trap device was outlined with simple lines, and then the structure of the generator set behind was simply outlined on this basis.

Staring at the more and more lines on the picture, which became clearer and clearer, Academician Qian gradually saw some doorways, and raised his eyebrows with interest.

"This, is this a ferrofluid generator?"

"Yes and no,"

Stopping the pen in his hand, Liu Feng looked at the sketch and nodded with satisfaction,

"I say yes because this power generation method is similar to the principle of magnetofluid generators, no, because although the principles are similar, in essence, this generator mainly generates electricity by controlling the high-energy charged mesons and some high-energy γ rays generated by the annihilation of antimatter. Of course, at my level, the design drawings can only be drawn to this extent, and the specific design has to be re-discussed by you experts. ”

When protons and antiprotons are annihilated, 3 to 7 mesons are produced, usually 3 charged mesons and 2 neutrons, of which the neutral mesons are converted into high-energy γ rays almost immediately, while the charged mesons have a certain lifespan, the normal half-life is 28 nanoseconds, but because they move at 94% of the speed of light, the half-life is extended to 70 nanoseconds, and they advance an average of 24 meters before the decay is completed.

These charged mesons, on the other hand, contain 60% of the energy annihilated by the positive and antimatter and are therefore easily charged, and can be used to propel the engine using a magnetic field to control their direction, and the high-energy γ rays converted by the neutron mesons can also be partially used elsewhere.

Therefore, it can be used to propel the engine, and naturally it can also be used to propel the 'generator', although the energy conversion efficiency in this is only about 60%, but compared to the 40% used to boil water, the efficiency is almost twice that of the latter!

Staring at the sketch, Academician Qian shook his head: " IMHO, your design is similar to the principle of magnetofluid generator, although it has a more attractive prospect, but you must know that magnetofluid fluid generator technology began to be developed as early as the 70s of the last century, but so far, decades have not been able to get decent results, the technology has not been perfect, and the economic benefits can not keep up with the needs of the market, so that it has gradually been abandoned by the mainstream of academia and industry, and it may not be a suitable choice to use it to generate electricity. ”

As if expecting Academician Wang to say this, Liu Feng smiled and continued:

"This is true for magnetofluid power generation, but not necessarily for our antimatter high-energy meson power generation. ”

"Oh?" the old lady's face showed an expression of surprise, and she turned her inquiring gaze to Liu Feng, "What do you say?"

Liu Feng: "As far as I know, the ferrofluid power generation technology is nothing more than heating the gas to a high temperature of 2000 degrees Celsius to form a plasma beam, and then cutting the magnetic field lines through the plasma beam to generate induced electromotive force for power generation, which seems to be something that many laboratories can do. ”

The old lady smiled: "However, these ferrofluid generators are coal-fired and fuel-oiled, heating the gas to a high temperature of 2000 degrees to form plasma, this process is accompanied by a large amount of heat energy loss, so almost no one can achieve an energy conversion efficiency of more than 20%, it is better to use these energy to boil water to generate electricity?"

"If it is antimatter power generation, we don't have such a problem at all," Liu Feng also smiled and continued, "Because we directly use the charged mesons after the annihilation of positive and antimatter to cut magnetic field lines and generate induced electromotive force for energy conversion, there is no such process as heating high-temperature gases to form plasma to propel the 'generator'! That is to say, we don't need to spend more energy to heat the ionized gas, we only need to use these mesons carrying huge energy!"

"Moreover, in addition to using charged mesons to 'push' the generator, we can also use additional high-energy γ rays to boil water or air, and 'push' another generator to generate electricity, which is equivalent to 'pushing' two generators to generate electricity at the same time, and the energy utilization rate is naturally far more than 60%!"

Hearing this, Academician Qian's expression moved.

Immediately looked at the sketch again, combined with Liu Feng's explanation just now, after a while, the old lady's eyes were excited......
