Chapter 115

After Zhang Wei taught Beidou all the useful knowledge he had, he let Beidou play by himself. As the first real AI in the world, Beidou can roam freely on the Internet, and can reach any corner of the Internet in an instant. In the last second, it may roam in China, and in the next second, it will go to the United States.

However, Zhang Wei ordered Beidou not to cause trouble or be found by others.

Beidou is very clever to agree, and then excitedly into the vast Internet world.

At this time, Zhang Wei finally has time to study the small fusion furnace technology that the system rewards.

He is full of expectation for this technology.

Nuclear technology, in addition to being able to make nuclear weapons, can also be used in medicine, industry and agriculture, and can solve the energy crisis of mankind.

At present, nuclear technology is divided into nuclear fission technology and nuclear fusion technology.

Nuclear fission is a kind of nuclear reaction in which a nucleus splits into several nuclei. It mainly refers to a form of nuclear reaction in which the heavy nucleus splits into two or more atoms with smaller mass. In this process, huge energy will be released. Only some very heavy nuclei, such as uranium and plutonium, can produce fission reactions. The atomic bomb uses nuclear fission technology.

At present, human beings have mastered the technology of controlled fission, such as the nuclear reactor of nuclear power plant.

In contrast to nuclear fission, nuclear fusion refers to the atom with small mass, mainly deuterium or tritium <. Under certain conditions, the atom nucleus polymerizes with each other to generate a new heavier nucleus, which will release more energy than the nuclear fission change. The light and heat of the sun is the fusion reaction from the internal hydrogen to helium.

At present, mankind has mastered the uncontrollable nuclear fusion technology, that is, hydrogen bomb! The power of hydrogen bomb is hundreds of times that of atomic bomb! It has been said that hydrogen bombs can bring the enemy back to the stone age!

However, uncontrolled nuclear fusion can only be used to make weapons of killing, and the energy it produces cannot be used by human beings at present.

Only by mastering the technology of controllable nuclear fusion can human use nuclear fusion to obtain energy, and it is infinite energy.

As we all know, helium 3 is recognized as a highly efficient, clean, safe and cheap nuclear fusion power generation fuel in the world. 8 tons of helium 3 can solve the total energy supply of China in one year. Every year, the world needs only 100 tons of helium 3.

Although there is little helium on the earth, the soil on the moon surface is rich in helium, which is estimated to be millions of tons. What is the concept of millions of tons of helium 3? This means that as long as mankind has mastered the controllable nuclear fusion technology and can develop the helium 3 resources of the moon, there will be no energy crisis for thousands of years!

Therefore, controllable nuclear fusion technology and space technology are related to the fate of the country!

However, controllable fusion technology is not to be realized, which is quite difficult!

Nuclear fission can occur only under the natural conditions of normal temperature, while the current human research on thermonuclear fusion needs a temperature of hundreds of millions of degrees in an instant, such a high temperature can not be achieved by traditional heating methods. In the development of hydrogen bomb, the temperature of nuclear fusion reaction is obtained by detonation of nuclear bomb, which causes the explosion of hydrogen bomb. So, there is a small nuclear bomb inside the hydrogen bomb.

Therefore, there are two key problems in the study of controllable fusion.

First: how to heat the fusion materials to such a high temperature?

Second: what will the fusion material take after it is heated to such a high temperature?

about the first question.

Nuclear physicists have designed a high-energy laser ignition device, such as the national ignition device in the United States. The laser will generate 192 laser beams, which will shoot at a spherical hydrogen target containing deuterium and tritium and cause it to collapse, and generate a high temperature of about 100 million degrees Celsius, thus triggering the fusion of hydrogen atoms. Moreover, the collision process between laser and hydrogen target is extremely short, lasting only a few nanoseconds.

On the second question.

So far, humans have not created any chemical structure that can withstand 10000 degrees Celsius, let alone hundreds of millions of degrees Celsius.

In order to solve this problem, we invented the Tokamak magnetic field confinement method, which uses the strong magnetic field generated by the strong current to confine the plasma in a small range to achieve nuclear fusion. Although it is close to success under laboratory conditions, it is far from being applied in industry.

So, although controllable nuclear fusion is beautiful, it is far away from human beings.

However, these difficulties need to be considered by others. Zhang Wei is not the same. He belongs to the person who is on the hook. The great inventor system has rewarded him with a complete set of technologies for making small nuclear fusion atomic furnaces.

……

With a solid foundation of knowledge, Zhang Wei took only five days to fully master the technology of small fusion atomic furnace which was awarded by the system.

At this time, he was completely shocked and couldn't help but live in his heart and praise the system!

Because this technology is more powerful than he thought.

First, the small nuclear fusion furnace is very small. How small is it? Minimum fist size! It's a real black technology, about the size of the ark reactor invented by Tony Stark in iron man.

And how big is the fusion reactor currently being studied?

Take the ITER project "artificial sun" for example.

ITER project, also known as the international thermonuclear fusion experimental reactor project, is led by China, the European Union, India, Japan, South Korea, Russia and the United States, with the participation of 35 countries, covering more than half of the world's population. It is now the world's second largest science and Engineering project after the international space station.

According to the public data, ITER experimental reactor is 24 meters high and 30 meters in diameter, with a planned volume of 840 cubic meters!

However, the diameter of the small nuclear fusion furnace is about 10 cm! Such an atomic furnace can be completely installed on intelligent robots, flying vehicles and other products.

The technology gap between them, at least hundreds of years!

Moreover, compared with ITER plan, the small nuclear fusion furnace technology mastered by Zhang Wei is a complete and controllable nuclear fusion technology that can be realized concretely!

Second, the small nuclear fusion furnace adopts the cold fusion technology, using palladium as the electrode. As long as the normal direct current heating causes palladium element to react, the ignition of the nuclear fusion reactor can be completed.

At present, the thermonuclear fusion technology that human beings are studying needs hundreds of millions of degrees of high temperature in an instant to complete the ignition of the fusion reactor.

The technology gap between them is like a natural moat.

Third, there is a new type of nanocomposite material in the materials of small-scale nuclear fusion atomic furnace. Its hardness is 30 times of that of titanium alloy steel, and its density is higher than that of titanium alloy. Its working temperature is between - 523 and - 3300 degrees. It has strong corrosion resistance and radiation resistance. The only problem: the cost is too high. If such materials are used to make an intelligent robot, the cost will definitely exceed 200 million yuan.

However, Zhang Wei is also preparing to produce more nano composite materials and build a group of powerful intelligent robots.

Fourth: the temperature of the reactor will continue to rise when the fusion reaction takes place, which is more than 20 million degrees Celsius like the sun center. There is no material in the world that can withstand such a high temperature. In order to solve this problem, the small fusion atomic furnace awarded by the system adopts a new technology, that is, the energy shield technology. The invisible and intangible energy shield is an airtight insulator, which can restrict the energy and temperature in the shield, so that the energy and temperature can not be transmitted out!

This energy shield technology makes Zhang Wei's eyes bright!
