Chapter 84: The Theory of Fusion

Money opens the way, and the company's qualifications, which originally took more than ten days to be approved, were successfully handled by Wilson in just a few hours.

Sitting in the moving car, holding a stack of documents in his hand, Shen Sen couldn't say whether he should criticize the corruption and disorder of this country, or whether he was glad that it was because of this that he had the opportunity to fish in troubled waters.

However, one day, when he can control this country, Shen Sen will definitely not allow this kind of behavior to exist.

The incorruptible should be incorruptible, enforce the law impartially, and realize their life pursuits, and without such an enlightened manager, he will not be condemned to this.

Since they themselves could not correct this shortcoming from human nature, as their leader, Shen Sen felt that he had an obligation to help them erase this false idea.

What cannot be done by ordinary education, under the effect of spiritual broadcasting, the leading group will achieve the most honest and just rule, and dedicate everything to the great cause of mankind with a selfless spirit and the most just means.

"In this way, it should be possible to achieve the so-called great harmony in the world, and everyone is for the public!"

When Shen Sen thought of this, a little expectation flashed in his dark pupils, which was perhaps the highest pursuit in his life.

Solving the problem of qualification for material purchase, Shen Sen didn't care about enjoying the luxurious life of the modern city, got in the car, and began to contact material suppliers everywhere.

In the STC standard material library of the Pioneer mecha, there are more than 1,700 production materials in total, and if they are arranged and combined, there are hundreds of material solutions that can be substituted for each other.

And to produce a primitive-level Pioneer light mech in its most perfect condition, a total of 137 materials are required.

When Shen Sen was leaving, Old Man Li once said that the STC factory did not have much requirements for the quality of materials.

Because whether it is the most primitive ore or steel that has entered the blast furnace, as long as it is sent to the STC standard factory, they will be re-smelted and combined in an intelligent processing center with thousands of production workshops on up to a dozen floors, and adjusted to meet the material properties by using high-energy magnetic fields and molecular oscillation equipment.

The difference is that iron ore is a little more energy-intensive than a synthetic metal that is already prepared.

And this is precisely where the problem lies, the STC factory in the wasteland is preparing STC templates that have been scrapped and disposed of, and it needs not much energy and fuel reserves left, and it cannot supply production for a long time.

In order to ensure the normal operation of the energy center, Old Man Li gave Shen Sen two options, it may be that his memory has become stronger because of the effect of spiritual energy, and he remembers those words clearly until now, and he does not drop a word.

"In the past, the energy supply of the STC plant was provided by the STC Production Directorate of the United States Department of Energy, which was responsible for delivering energy fuels according to demand, such as fusion fuel collected on nearby asteroids and artificially created antimatter.

The first is easier to obtain, and it is also more low-level, and the leader can find a way to get some fusion fuel, such as deuterium tritium, which is easier to ignite, burns at a lower temperature, and is easier to control.

What the old man needs to tell the leader is that there is not much left in the wasteland of these two fuels, and we have used them up, so we don't know if there is one in the other world where the leader goes.

If there is, that's the best result, and if not, it's okay to make some hydrogen, but the critical temperature of proton fusion is relatively high, and the pressure is relatively high.

In view of the fact that we only have this set of equipment left, the attrition rate is too high, and if any part is damaged, it is really difficult to repair, and the best case scenario is that the leader can find deuterium tritium. ”

What Old Man Li said, as a science fiction lover, Shen Sen also understood it.

The central mechanism of nuclear fusion is the strong interaction that binds the neutrons and protons of different atoms together.

The hydrogen nucleus is a single proton, and the interaction between protons and protons is dominated by the Coulomb force between nucleons most of the time, and the electrostatic field is too strong for the two protons to be able to approach and let the strong interaction play a major role. The probability of such a fusion occurring is extremely small.

However, when the nuclei are close to each other to the range of strong interactions, there is a high probability that the nucleons will break through the barrier of mutual repulsion of the Coulomb force (quantum tunneling) and eventually attract each other.

The range of the strong interaction is similar to the radius of the nucleus. If we put aside too much theoretical analysis, it can be said that the smaller the charge, the greater the radius of the nucleus, the more likely it is to fuse between the nuclei.

Therefore, deuterium and tritium, which also have a positive charge and a much larger radius of the nucleus, are more likely to fuse.

For example, deuterium-tritium fusion takes about 100 million degrees, while the temperature of the solar center in Shen Sen's previous galaxies was only 15 million degrees, and hydrogen lithium 7 requires tens of billions of degrees.

This fusion can occur in an optically thick environment, where there is no loss of radiant energy and the temperature is extremely high, such as in the case of a supernova explosion.

However, with the technology of Old Man Li and his team, the realization of hydrogen or lithium fusion under engineering conditions, that is, the energy gain generated, is simply not enough to make up for the energy and equipment losses to maintain fusion.

In popular understanding, that is, it cost 10,000 yuan and got a benefit, which is not cost-effective at all.

But these are not the point, the point is that the fuel on the wasteland actually let Old Man Li and them run out, it is unimaginable!

Didn't experts say that with nuclear fusion, there is an endless source of energy?

Shen Sen remembers very well that the global energy consumption given by a professional scientific research organization on the earth is about 10∧14W, and doing a mass-energy conversion is equivalent to consuming a little more than one gram of matter per second.

Convert to fusion, consider the problem of energy utilization, that is, a dozen kilograms to tens of kilograms of deuterium tritium. At this rate of consumption, there is enough deuterium on Earth for 90 billion years.

Even if there are not many reserves on the wasteland planet, Old Man Li said that they are still mining on the surrounding asteroids, and they can also artificially create antimatter, and the population is not as large as on the earth.

If the experts are right, it will not be wasted in so many decades.

But when Shen Sen asked this question, Old Man Li first looked at Shen Sen in surprise, and then suddenly explained.

"The leader should have obtained this knowledge from that world, it's incredible, it seems that that planet is a very rare civilization world, but their technological development is a little too backward, and they may not have encountered this problem.

Let me tell you a simple parable that my teacher's teacher once said.

At that time, his old ancestor once said that primitive humans looked at the forest and sighed that so much wood would never be used up for cooking and heating, but later, who shaved the green mountains.

And modern human beings look at coal and oil, and say the same thing as their ancestors, but now, is it gone?

How high and far to see, the level of science and technology is the level of energy consumption, with the development of civilization, the growth of energy consumption is beyond the exponential.

In the past, humans may have felt that hundreds of kilograms of fusion fuel could provide the entire year of consumption for a planet, but in a thousand years, this consumption may reach tens of millions, or even hundreds of millions, times that of today.

For example, the damaged atmospheric regulation systems of Rain God and Thor above our heads, if converted into nuclear fusion fuel, consume hundreds of tons per day, but this is mainly on the premise of relying on solar energy.

However, their words cannot be said to be completely wrong, it is true that sticking to one planet is not inexhaustible, but when we enter the sea of stars and technology develops to an unimaginable level, this sentence may be true! ”
