Urban Inventor

After Zhang Wei taught Beidou all the useful knowledge he had mastered, he let Beidou play by himself. As the world's first real artificial intelligence, Beidou can run amok on the Internet, and can reach any corner of the Internet in an instant. One second may be wandering in China, and the next second it will go to the United States. .

However, Zhang Wei still ordered Beidou not to cause trouble, and not to be discovered by others.

Beidou obediently agreed, and then excitedly got into the vast Internet world.

At this time, Zhang Wei finally had time to study the small nuclear fusion atomic furnace technology rewarded by the system.

For this technology, he is full of expectations.

Nuclear technology, in addition to being able to manufacture 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 change in which an atomic nucleus splits into several atomic nuclei. It mainly refers to a form of nuclear reaction in which a heavy atomic nucleus splits into two or more atoms with smaller masses. In this process, huge energy is released. Nuclear fission reactions can only occur in some very heavy nuclei like uranium, plutonium and other elements. The atomic bomb uses nuclear fission technology.

At present, humans have mastered controllable nuclear fission technology, such as nuclear reactors in nuclear power plants.

Nuclear fusion is the opposite of nuclear fission. It refers to atoms with small masses, mainly deuterium or tritium (helium 3 is also available). Under certain conditions (such as ultra-high temperature and high pressure), atomic nuclei will polymerize with each other to generate new masses. Heavier nuclei, such as helium, release more energy in this process than nuclear fission. The light and heat of the sun come from the nuclear fusion reaction of internal hydrogen fusion into helium.

At present, mankind has mastered the uncontrollable nuclear fusion technology, that is, the hydrogen bomb! The power of a hydrogen bomb can be said to be hundreds of times that of an atomic bomb! Someone said that the hydrogen bomb can bring the enemy country back to the stone age!

However, uncontrollable nuclear fusion can only be used to create the ultimate killing weapon that can destroy human beings, but the energy it produces cannot be used by human beings at present.

Only when human beings have mastered the controllable nuclear fusion technology can they use nuclear fusion to obtain energy, and it is unlimited energy.

As we all know, helium 3 is recognized as an efficient, clean, safe and cheap fuel for nuclear fusion power generation in the world. 8 tons of helium 3 can solve the total energy supply of the whole of China for a year, and the energy needed by the world every year is only 100. tons of Helium 3.

Although the reserves of helium 3 on the earth are very small, the soil on the surface of the moon is rich in a large amount of helium 3, and it is estimated that there are millions of tons of helium 3. What is the concept of millions of tons of helium 3? This means that as long as human beings master 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 aerospace technology are related to the destiny of the country!

However, the controllable nuclear fusion technology is not something that can be realized, and the difficulty is quite high!

Nuclear fission can occur as long as it is under natural conditions at normal temperature, while the thermonuclear fusion studied by human beings needs instantaneous high temperature of hundreds of millions of degrees to be triggered. Such a high temperature cannot be achieved by traditional heating methods. When human beings develop the hydrogen bomb, they detonate the nuclear bomb to obtain the temperature of the nuclear fusion reaction, thereby causing nuclear fusion and causing the hydrogen bomb to explode. Therefore, there is a small nuclear bomb inside the hydrogen bomb.

Therefore, there are two most critical issues in the study of controllable nuclear fusion.

First: How to heat the raw material for nuclear fusion to such a high temperature? (How to ignite the fuel in the stove?)

Second: After heating the raw material for nuclear fusion to such a high temperature, what will be used to hold it? (How to keep the fuel from burning through the stove?)

Regarding the first question.

Nuclear physicists have designed a high-energy laser ignition device,

For example, in the National Ignition Device of the United States, the laser will generate 192 laser beams, which will be shot at a hydrogen spherical target containing deuterium and tritium to cause it to collapse, and generate a high temperature of about 100 million degrees Celsius, thereby triggering the fusion of hydrogen atoms. Moreover, the collision process between the laser and the hydrogen target pellet is extremely short, lasting only a few nanoseconds (1 nanosecond is equal to 1 billionth of a second).

Regarding your second question.

So far, humans have not created any chemical structure that can withstand 10,000 degrees Celsius, let alone hundreds of millions of degrees Celsius.

In order to solve this problem, humans invented the "tokamak" type magnetic field confinement method, which uses a strong magnetic field generated by a strong current to confine the plasma to a small range to achieve nuclear fusion. Although it is close to success in laboratory conditions, it is still far from reaching industrial application.

Therefore, although controllable nuclear fusion is very beautiful, it is still far away from human beings.

However, these difficulties are something that other people need to consider. Zhang Wei is different. He belongs to the hacker. The Great Inventor System has rewarded him with the full set of technologies for manufacturing small nuclear fusion atomic furnaces. All he needs to do is digest and absorb this knowledge!

...

Thanks to his solid knowledge base, Zhang Wei only took five days to fully master the small nuclear fusion atomic furnace technology rewarded by the system.

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

Because this technology is even more powerful than he imagined.

First: The small nuclear fusion atomic furnace is very small, how small is it? The smallest can reach the size of a fist! This is real black technology, about the same size as the Ark reactor invented by Tony Stark in the movie "Iron Man".

And how big is the nuclear fusion reactor that humans are currently studying?

Take the "artificial sun" ITER project as an example.

The ITER program, also known as the International Thermonuclear Experimental Reactor Program, is led by China, the European Union, India, Japan, South Korea, Russia and the United States, and 35 countries participate together, covering more than half of the world's population. The International Science and Engineering Program of the Space Station.

Public information shows that the ITER experimental reactor has a height of 24 meters and a diameter of 30 meters, and the planned plasma volume is 840 cubic meters!

However, the diameter of a small nuclear fusion atomic furnace is only about 10 centimeters! Such an atomic furnace can be installed on products such as intelligent robots and flying cars.

The technological gap between them is at least several hundred years!

Moreover, compared with the ITER project, Zhang Wei's small-scale nuclear fusion atomic furnace technology is still a complete and controllable nuclear fusion technology that can be realized concretely!

Second: The small-scale nuclear fusion atomic furnace adopts cold nuclear fusion technology, and palladium is used as an electrode. As long as the normal direct current heating allows the palladium element to react, the nuclear fusion reactor can be ignited.

The thermonuclear fusion technology that humans are currently researching requires instantaneous high temperatures of hundreds of millions of degrees to complete the ignition of nuclear fusion reactors.

The technological gap between them is like a natural moat.

Third: There is a new type of nano-composite material among the materials of small nuclear fusion atomic furnaces. Its hardness is thirty times that of titanium alloy steel, and it is also denser than titanium alloy. Strong corrosion resistance and strong radiation resistance. The only problem is: the cost is too high. If such materials are used to manufacture an intelligent robot, the cost will definitely exceed 200 million yuan.

However, Zhang Wei is also preparing to grit his teeth and produce more of this nanocomposite material to create a group of powerful intelligent robot subordinates.

Fourth: When the nuclear fusion reaction occurs in the reaction body, the temperature will continue to rise, exceeding 20 million degrees Celsius like the center of the sun. There is no material in the world that can withstand such a high temperature. In order to solve this problem and prevent the high temperature of the reactant from burning through the atomic furnace, the small nuclear fusion atomic furnace rewarded by the system adopts a brand new technology, that is, the energy shield technology. The invisible and intangible energy shield is An airtight insulator can confine energy and temperature within the shield, preventing energy and temperature from being conducted out!

This energy shield technology made Zhang Wei's eyes shine!
