"Is this...?"

After seeing this twisted twist-shaped special device displayed on the booth, Xu Lei suddenly felt familiar and vaguely guessed what it was.

Then, in order to confirm his guess, he immediately turned his attention to the information screen without any hesitation.

Suddenly the content that appeared above jumped into my eyes.

Name:Controllable nuclear fusion technology

Level: First level civilization

Evaluation: The illuminator of the universe, the sign that civilization has entered the first level.

Influence:0/10 million

Collection unit: Universe Civilization Science and Technology Museum

"As I guessed, what was unlocked this time turned out to be controllable nuclear fusion technology. No wonder the device displayed gave me a sense of familiarity."

After seeing the booth introduction template information on the information screen, Xu Lei couldn't help but murmured softly.

I didn't expect that the exhibit I unlocked this time would be this.

The so-called controllable nuclear fusion refers to a nuclear fusion reaction that controls the speed and scale of nuclear fusion under certain conditions to achieve safe, sustained and stable energy output.

The change of one atomic nucleus into another is often accompanied by a huge release of energy.

If a heavy atomic nucleus changes to a light atomic nucleus, it is called nuclear fission; if a light atomic nucleus changes to a heavy atomic nucleus, it is called nuclear fusion.

At the center of the sun, the temperature reaches 15 million degrees Celsius and the air pressure reaches more than 300 billion atmospheres.

Nuclear fusion reactions consume about 5 million tons of material every second.

And converted into energy and released.

For billions of years, the sun has been like a huge nuclear fusion reaction device, releasing energy endlessly, and like other stars, its power comes from fusion energy.

As the museum says about this technology, it is nuclear fusion that lights up the universe.

In a sense, the fossil energy sources currently used by humans, such as wind energy, are ultimately derived from fusion energy from the sun.

As human beings have developed to this day, indirect acquisition of fossil energy can no longer meet demand.

So in this case, nuclear fusion becomes the hope of mankind.

Only by truly mastering this ultimate energy can mankind continue to develop. At that time, those views that advocate that modern industry will perish because there is no energy source will also go bankrupt.

In short, nuclear fusion determines the survival and destruction of mankind.

If it is solved, human material civilization can continue to develop; if it cannot be solved, mankind will fall into an unprecedented crisis.

For this reason, many countries around the world have established relevant laboratories and are always conducting research on controllable nuclear fusion, hoping that one day they can truly control it.

However, as of today, it is still in the research stage.

Xu Lei knew that the Chinese Academy of Sciences had reached a cooperation intention with other overseas fusion laboratories in the past few days, and was preparing to gather global forces to jointly launch a charge on nuclear fusion, and planned to achieve it within five years.

But thinking that new exhibits would be unlocked soon, I didn’t participate.

But I never expected that the booth unlocked this time would be controllable nuclear fusion technology.

I don’t know if it’s a simple coincidence or if the museum did it intentionally.

certainly.

Xu Lei is very satisfied with this technology.

Controllable nuclear fusion determines the potential for the development of human civilization. Mastering this technology can completely change the energy structure used by society today.

At the same time, we develop nuclear fusion-powered spaceships, high-speed trains, and powerful laser weapons.

By that time, building a Mars base will also become a very simple matter.

However, Xu Lei still complained a little about the requirements for influence. Unexpectedly, it was the same as virtual reality technology.

It needs to reach tens of millions of points of influence.

Although to a certain extent, controllable nuclear fusion technology has a greater impact on human beings than virtual reality, at least the virtual helmets produced through virtual reality technology are not lacking in sales and can quickly become a hot-selling product around the world. In this way, within a few months

Completion of influence requirements within.

At present, controllable nuclear fusion also requires tens of millions of influence to continue to unlock new exhibits. The best way is to apply it to as many fields as possible.

But you must know that the current human research on controllable nuclear fusion requires very large devices.

This alone has many limitations.

However, the situation has become like this, and now we can only take one step at a time.

"It seems that this time the impact can only come slowly. Now let me see what is unique about this technology collected in the museum."

Xu Lei's thinking was very clear at this time.

No matter how this technology gains a large amount of influence, the first thing to do is to create a controllable nuclear fusion device through an understanding of technical knowledge, otherwise everything will be pale.

After his thoughts stopped here, Xu Lei naturally did not hesitate any longer and immediately stretched out his finger to point on the note in the lower right corner of the information screen.

suddenly.

The template data content originally on the information screen disappeared.

What replaced it was the detailed technology of nuclear fusion.

Because Pei Hongyin, the vice president of the Future Science and Technology Research Center, was in charge of the artificial sun project of Luyang Science Island before he retired.

Later, it was handed over to the younger and more outstanding Li Chengzhe.

In addition, Pei Hongyin has always had a strong obsession in his heart, hoping to see the actual advent of a controllable nuclear fusion device in his lifetime.

Therefore, there was still no research at the research center, and Shi Chang analyzed and studied this technology through the capabilities of Star Pupil and quantum computers.

This made Xu Lei somewhat aware of it.

The difficulty of controllable nuclear fusion technology lies in artificial ultra-high temperature.

Nuclear fission can occur spontaneously or under stimulation, but nuclear fusion must occur under ultra-high temperature and ultra-high pressure conditions, which is why nuclear fusion is difficult to achieve.

It is difficult to achieve both ultra-high pressure and ultra-high temperature in an artificial physical environment. However, if you want to achieve nuclear fusion, you must create a high-temperature environment more extreme than that of the sun.

But looking at all the materials in human cognition, it is impossible to withstand continuous high temperatures of one billion degrees.

In this case, physicists proposed to make the fusion plasma suspended in the vacuum by cleverly constructing a non-contact supporting magnetic field.

thereby constraining it.

And by controlling the adding speed of nuclear fusion fuel and the amount added each time, the nuclear fusion reaction can be carried out continuously or rhythmically on a certain scale.

For this reason, physicists also proposed the criterion of fusion triple product.

That is, the product of the temperature density and confinement time of the plasma.

Only when this basic value is exceeded, the power output by the fusion body is greater than the power input to drive the reaction.

Achieve usable energy output.

In today's society, people's research on nuclear fusion is divided into two directions.

They are magnetic field constraints and inertia constraints respectively.

As for Pei Hongyin’s research direction, it is the tokamak device of magnetic field confinement device.

However, as Xu Lei examined and studied the detailed technical knowledge on the information screen, his expression involuntarily became serious.

It seems like something else has been discovered.

I don’t know how much time passed before Xu Lei finally made a new move.

He slowly moved his eyes away from the information screen.

"It is indeed unique to be collected by a museum. It seems that Lao Yang and the others still have a lot of detours to take this time if they want to develop controllable nuclear fusion!"

At this time, Xu Lei recalled the information that had just been transmitted in his mind, and subconsciously muttered this sentence.

Because this international cooperation is mainly focused on the artificial solar project of the Science Island of the Chinese Academy of Sciences, the research direction must also be the magnetic field-constrained Tokamak device.

But the unlocked controllable nuclear fusion technology is not like that.

According to Xu Lei's understanding, the controllable nuclear fusion technology in the museum is a composite design that combines magnetic confinement and inertial confinement.

At the same time, the magnetic field confinement device is similar to a stellarator.

If the tokamak device is a donut, then the stellarator is a twist.

Compared with tokamak, stellarator can operate in a steady state and does not have the difficulty of generating plasma current.

It is the only fusion device that does not require external energy after ignition.

Tokamak has the advantage of simple technology and low cost, so it is favored by various fusion laboratories.

Of course, the device used in the controllable nuclear fusion technology in Xu Lei's mind must be more powerful than the stellarator known to the public today.

It can be said to be an optimized version.

The key thing that Xu Lei likes most is that the stellarator does not require a very large volume like a tokamak device.
