Is it reasonable for me to build a space elevator when filming The Wandering Earth?

Hearing Liu Lang's words, Shi Lei couldn't help but be stunned.

Recently, I got the news about Liu Lang from the security department, or his film performed well in the international film market, earning billions of box office.

Liu Lang has properly become a rising director star in China and even around the world.

Shi Lei almost forgot for a while that the other party was a scientific research expert in 'radiating radar electromagnetic waves' and 'carbon nanotube materials'.

Of

course, we know that a certain degree of controlled nuclear fusion has been achieved in many scientific research institutions in many countries.

The problem is that the energy of ignition and maintenance is smaller than the energy output of the fusion reaction, and it only consumes electricity but does not generate electricity, so it is currently mainly used as a neutron source.

Among them, electrostatic inertial confinement fusion devices are simple and easy to manufacture...

Listening to Shi Lei's eloquent conversation on the other end of the phone, Liu Lang was a little stunned.

He didn't expect that Shi Lei, who was born in the army, would also know about this kind of international cutting-edge scientific research project.

"Brother Leizi, how do you know so clearly

? Take the liberty of asking, isn't your education an adult junior college?

Of course, I'm not discriminating... "

Listening to Liu Lang's words, Shi Lei had a black line, thinking that you are just a bachelor's degree from a film and television academy, just in terms of the gold content of academic qualifications, how much higher can you be than me?"

Last month, a technical school student said that he had mastered the technology of controlled nuclear fusion, and said that he wanted to rely on it to upgrade his education.

I personally led the team to the scene to deal with it, and I was full of expectations, but it turned out that guy made it a 'electrostatic inertial confinement fusion device' for a long time, and the practicality was almost zero, which made us happy in vain.

"Hey, did you succeed in giving him a special upgrade?"

"Of course not, if he can do nuclear fission, it's about the same, but then he will probably have to be supervised by the Security Bureau for the rest of his life, and he is a potential social terrorist."

Far away, why are you mentioning 'controlled nuclear fusion'?

Could it be that there are any progress achievements in controlled nuclear fusion?!"

Compared with the unreliable technical school student, Liu Lang is undoubtedly much more reliable.

Although Liu Lang's academic qualifications are only an undergraduate student in the School of Film and Television, he is a scientific research expert who has provided 'radiation radar electromagnetic wave shielding device' and 'carbon nanotube material industrial mass production technology'.

No matter how different Liu Lang's identities as a director and a scientific research scholar are, just for the sake of his two scientific research achievements, the head of the Security Bureau should pay him corresponding attention.

However, controlled nuclear fusion, which belongs to the scientific research field of 'nuclear physics', is very different from the 'carbon nanotube materials' of polymer materials science and the field of radar electromagnetic waves.

Although in Shi Lei's heart, Liu Lang is an amazing talent of non-governmental self-taught scientific research giants, he does not think that Liu Lang can make any amazing breakthroughs in 'controllable nuclear fusion'.

After all, this question has puzzled the world's 'nuclear physics' scholars for decades.

"Well, it really has something to do with it.

I'm talking about controlled nuclear fusion of heavy elements. "

Controlled nuclear fusion of heavy elements?!"

This really touched Shi Lei's knowledge blind spot.

"To put it simply, what you call controlled nuclear fusion, to be precise, there are many forms of fusion reactions, including deuterium-deuterium (D-D) reactions, deuterium-tritium (D-T) reactions, deuterium-helium-3 (D-He3) reactions, etc.

At present, the fusion community generally believes that the (D-T) reaction is the easiest fusion reaction to achieve, because it requires the lowest triple product, that is to say, the required reaction conditions are the easiest to achieve, and scientists from all over the world are working hard to achieve stable combustion of D-T fusion reaction.

He3 is almost non-existent on Earth, but it is abundant on the Moon, and it is one of the decay products of T. Both D and T are isotopes of hydrogen (H).

The storage of the D element in the seawater is very abundant and can be considered almost inexhaustible. However, the T element is not, in the entire earth, in the heavens, the earth and the sea, there are only 3.6kg of T element, such a small amount of T is distributed in all corners of the world, it cannot be used by people.

As a result, the initial stage of fusion research can only rely on artificial production, such as the ITER - International Thermonuclear Experimental Reactor in the world today.

At present, the world's T production mainly uses CANDU heavy water reactors, with an annual output of about 100g, while a 1GW fusion power station consumes about 56kg of T per year.

Also, T is a radionuclide that decays by about 5% per year. Therefore, how to get enough startup T and store it for application is also a big problem.

All in all, whether the 'controlled nuclear fusion' that mankind is carrying out so far can provide mankind with nearly unlimited energy depends on the face of "tritium" at this stage.

Shi Lei, who looked confused, listened to Liu Lang's research direction on controlled nuclear fusion in the world, and probably figured out what he meant, the material problem is the biggest difficulty in controlled nuclear fusion at present.

"Ahem, these are indeed the current problems in the world's scientific community, but what does this have to do with the 'controlled nuclear fusion of heavy elements' you mentioned?

"What I mean by 'controlled nuclear fusion of heavy elements' means that under the premise of ensuring that nuclear fusion is controllable, all elements in the periodic table, from hydrogen to above, below iron, can be used as fuel for heavy nuclear fusion.

To put it simply, it is possible to use a controlled fusion reactor as fuel simply by 'burning stones'.

It perfectly solves the material problems faced in deuterium-tritium controlled nuclear fusion!"

Liu Lang broke the meaning of 'heavy nuclear fusion' and explained it to Shi Lei, who can realize the significance and value of this 'heavy nuclear fusion' technology even if he is not a scientific researcher.

"So, Mr. Liu, have you successfully experimented?"

"I can't build a heavy fusion reactor myself, and if I want to ignite a heavy fusion reactor, I must first input a large amount of energy to make the ignition point temperature meet the standard."

Its temperature requirements are a bit harsh, and at present, it is probably only the effect of a nuclear weapon explosion that can meet the requirements.

However, I can assure you that as long as the 'heavy nuclear fusion reactor' is built according to the drawings I provided, the controllable nuclear fusion of heavy nuclear elements will definitely be realized!"

Hearing Liu Lang's solemn promise, Shi Lei also became more serious than ever.

Liu Lang has never joked about this kind of scientific research project, if what the other party said is true, then this is definitely a technology that is 100 times more important than the 'industrial mass production of carbon nanotube materials'!
