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 rampant on www.biquge.info the Internet, and can reach any corner of the Internet in an instant, one second it may be hanging out in China, and the next second it will run to the United States.

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

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

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

He is full of expectations for this technology.

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

Currently, nuclear technology is divided into nuclear fission technology and nuclear fusion technology.

Nuclear fission is a change in the splitting of an atomic nucleus into several atomic nuclei, mainly refers to a form of nuclear reaction in which a heavy nucleus splits into two or more atoms with a smaller mass, and a huge amount of energy is released in the process. Only some very massive nuclei such as uranium, plutonium and other elements can undergo nuclear fission reactions. The atomic bomb uses nuclear fission technology.

At present, mankind has mastered the technology of controlled nuclear fission, such as the nuclear reactor of nuclear power plants.

Nuclear fusion, on the other hand, is the opposite of nuclear fission, which refers to atoms with small masses, mainly deuterium or tritium (helium-3 is also acceptable), and under certain conditions (such as ultra-high temperature and high pressure), the nuclei of the atoms polymerize with each other to form new nuclei with heavier mass (such as helium), and in this process will release greater energy than nuclear fission. The sun's light and heat are nuclear fusion reactions that come from the fusion of hydrogen into helium.

At present, mankind has mastered the uncontrollable technology of nuclear fusion, that is, the hydrogen bomb! The power of the hydrogen bomb can be said to be hundreds of times that of the atomic bomb! Some people have said that the hydrogen bomb can return the enemy country to the Stone Age!

However, uncontrollable nuclear fusion can only be used to make murder weapons, and the energy generated by it cannot be used by humans at present.

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

As we all know, helium-3 is recognized as an 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 the whole China for a year, and the energy required by the world every year is only 100 tons of helium-3.

Although helium-3 is found in very small quantities on Earth, the surface soil of the moon is rich in large quantities of helium-3, which is initially 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 technology of controlled nuclear fusion and can develop the helium-3 resources of the moon, there will be no energy crisis for thousands of years!

Therefore, controlled nuclear fusion technology and aerospace technology are related to the fate of the country!

However, controlled nuclear fusion technology is not something that can be achieved if you want to achieve it, and it is quite difficult!

Nuclear fission can occur as long as it is at room temperature, while thermonuclear fusion, which is currently researched by humans, requires an instantaneous high temperature of hundreds of millions of degrees Celsius to initiate, and such a high temperature cannot be achieved by traditional heating methods. When humans develop hydrogen bombs, they detonate nuclear bombs to obtain the temperature at which they reach the nuclear fusion reaction, which causes nuclear fusion to explode hydrogen bombs. So, there is a small nuclear bomb inside the hydrogen bomb.

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

First: How do you heat the raw materials for nuclear fusion to such a high temperature? (How do you ignite the fuel in the furnace?)

Second: What to use to heat the raw material for nuclear fusion to such a high temperature? (How do you keep the fuel from burning through the furnace?)

On the first question.

Nuclear physicists have devised high-energy laser ignition devices, such as the National Ignition Facility in the United States, which generates 192 laser beams that crash into a deuterium-tritium-containing hydrogen spherical target and generate a temperature of about 100 million degrees Celsius, triggering hydrogen fusion. Moreover, the collision process between the laser and the hydrogen target is extremely short, lasting only a few nanoseconds (1 nanosecond equals 1 billionth of a second).

On the second question.

To date, 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, mankind invented the "tokamak" type magnetic field confinement method, which uses a strong magnetic field generated by a strong electric current to confine the plasma to a small range to achieve nuclear fusion. While success is close to success under laboratory conditions, it is still far from reaching industrial applications.

Therefore, although controlled nuclear fusion is beautiful, it is still far from humans.

However, these difficulties are something that other people need to consider, but Zhang Wei is different, he belongs to the people who are hanging, and the great inventor system has rewarded him with the full set of technology for making small nuclear fusion atomic furnaces.

……

Due to his solid knowledge base, Zhang Wei only took five days to thoroughly master the system-rewarded small nuclear fusion atomic furnace technology.

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

Because this technology is even more awesome than he imagined.

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

And how big are the nuclear fusion reactors that humans are currently working on?

Take, for example, the "Artificial Sun" ITER program.

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, with the participation of 35 countries, covering more than half of the world's population, and is currently the world's second largest international scientific engineering program after the International Space Station.

According to public information, the ITER experimental reactor has a height of 24 meters, a diameter of 30 meters, and a planned volume of 840 cubic meters of plasma!

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

The technological gap between these is at least a few hundred years!

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

Second: the small nuclear fusion atomic furnace uses cold nuclear fusion technology, using palladium as an electrode, as long as the normal direct current heating allows the palladium element to react, the ignition of the nuclear fusion reactor can be completed.

At present, the thermonuclear fusion technology being studied by mankind requires hundreds of millions of degrees of heat to complete the ignition of nuclear fusion reactors.

The technological gap between them is like a moat.

Third: there is a new type of nanocomposite material among the materials of the small nuclear fusion atomic furnace, which is 30 times harder than titanium alloy steel, and is denser than titanium alloy, with a working temperature of minus 523 to minus 3300 degrees, strong corrosion resistance and radiation resistance. The only problem is that 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 ready to grit his teeth and produce a little more of this nanocomposite material to create a group of powerful intelligent robot subordinates.

Fourth: When the reactor undergoes a nuclear fusion reaction, the temperature will continue to rise, like the center of the sun, more than 20 million degrees Celsius, and there is no material in the world that can withstand such high temperatures. In order to solve this problem, the system-rewarded small nuclear fusion atomic furnace adopts a new technology, that is, the energy shield technology, the invisible and intangible energy shield is an impermeable insulator, which can confine energy and temperature in the protective shield, so that energy and temperature cannot be conducted!

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