Metropolis: My IQ is 300

Chapter 169

Chapter 164 If it's Chen Fan, I'm willing to sell it in packages (seeking subscription, second)

In August, the sky was very good. The university welcomed a new holiday. Many students left the school. This time, Chen Fan did not go home, but stayed at the school and called home.

It seems that doing scientific research has become a habit.

After eating breakfast with Nie Sisi, the two sat in the laboratory, writing a design book.

On the table, a hanging stone is Chen Fan's latest achievement.

"Teacher, I have calculated that according to this ratio, the cost of this is too high."

"I naturally know that it is because it is too high, so it can only be seen as a joke at the moment."

"What about nuclear fusion?"

"I don't know, don't ask me, I don't have a place to experiment now, how can I do this?"

It seems to be the truth. ,

Two people, big and small, looked at each other, not knowing what they were doing for a while.

"Or, I'll take you out to watch the fun."

"Ah, is the teacher a new subject?"

"No, I just think I should take you to see the excitement. I have been in the laboratory. I can hold it. You are not good enough. You are still growing."

Nie Sisi nodded.

The two changed into clothes.

Xiao Mei is in charge of looking at home, and of course the voice of Xiao Mei is transmitted in the earphones.

When they were out of school, the two of them were a little at a loss. Tao Yaoyao was responsible for their travels. Suddenly, they were very uncomfortable when they traveled by themselves.

"How to deal with it?"

"Xiaomei will plan, and Xiaomei will book us a chartered car."

"Okay, user, in fifteen minutes, the vehicle will arrive at your address."

Chen Fan bought some fruit for Nie Sisi to eat.

"Teacher, why don't you eat ginseng fruit."

"That can't be mass-produced. Your body needs too much nutrition to maintain it. If you have bracelets, you don't need these."

"Well, I feel like I'm a lot worse. Recently, I just solved the Mason prime number."

"It's okay. Take your time. Mathematics is the foundation. You can learn other subjects after you learn it well. If you can't do mathematics, don't talk about other subjects."

"But I feel that I have learned a lot and found that I don't understand mathematics more and more."

"I don't know how to comfort you, but it's probably, in fact, this thing is not that difficult, just like this, this way, and then this way, understand?"

"understood."

Great, this is much smarter than the previous students, f*ck.

Some of the newcomers I brought before, Chen Fan now remembered that his back was sweating cold, wipe it.

Thermonuclear reaction [1], or the fusion reaction of atomic nuclei, is currently a promising new energy source. The hydrogen nuclei involved in nuclear reactions, such as hydrogen (protium), deuterium, tritium, lithium, etc., obtain the necessary kinetic energy from thermal motion and cause the fusion reaction (see nuclear fusion). The thermonuclear reaction is the basis of the hydrogen bomb explosion, which can generate a large amount of heat in an instant, but it cannot be used yet. If the thermonuclear reaction can be generated and carried out in a controlled manner according to people's intentions in a certain restricted area, a controlled thermonuclear reaction can be realized. This is a major subject of experimental research currently being carried out. Controlled thermonuclear reaction is the basis of fusion reactors. Once the fusion reactor succeeds, it may provide mankind with the cleanest and inexhaustible energy source.

D (deuterium) and T (tritium) fusion will produce a large number of neutrons, and carry a large amount of energy (), neutrons are very dangerous to the human body and living things.

The real trouble with fusion neutrons is that neutrons can react with the walls of the reactor. It must be replaced after a period of use, which is very costly. And the replaced wall may be radioactive (depending on the choice of wall material) and become nuclear waste. Another bad factor is that tritium is radioactive, and tritium may also react with walls.

Deuterium-tritium fusion can only be regarded as "first-generation" fusion. The advantage is that the fuel is extremely cheap, but the disadvantage is that it contains neutrons.

The "second generation" fusion is the reaction of deuterium and helium 3. This reaction itself does not produce neutrons, but since there is deuterium in it, the deuterium-deuterium reaction will also produce neutrons, but the total amount is very, very small. If the first-generation power station must be far away from the downtown area, the second-generation power station is estimated to be placed directly in the city center.

The "third generation" fusion is to make helium-3 react with helium-3. This fusion produces no neutrons at all. This reaction can be called the ultimate fusion.

The information in the mobile phone was shared with Chen Fan by the Chinese Academy of Sciences. The information is extremely valuable. It took Chen Fan a long time to find it.

"Teacher, this, nuclear fusion, I think, if it is combined with your nuclear power, does it have inexhaustible energy?"

"Stupid, you forgot the fluid theory that the teacher developed before. Did you lose energy?"

"Remember, but if you calculate according to time, it will take a long, long time."

.. .... 0

"Yes, it has been a long time, no need for people to wait, but energy conservation will not change."

Chen Fan took a bite of the apple, which was not bad, the farmer’s.

Nie Sisi also took a bite.

"Is that, when you have this energy, teacher, you can build a house suspended in the sky?"

"Probably it is possible, but you have to have a concept, suspended, such a large place, what is the material I need, in addition, you must not forget a core point, how to send it up, how to build on it, these are all It's the problem."

His head hurts, his head hurts, and he subconsciously touched his hair. Now Nie Sisi feels that he is going to be bald.

Nie Sisi's identity is Chen Fan's younger sister, who was asked by Chen Fan to write it in the account book.

The specially rented vehicle drove over, and the two sat in the back seats.

"Guest, where are you going?"

"Go and take a look at the World Trade Center."

"Are you also attending a sociology seminar?"

"Uh, no, I went to see my girlfriend."

Nie Sisi nibbled the apple again. The apple was not tasty, it was a bit bitter, and a bit sour. It was strange, it was still sweet before.
