Fusion releases energy by merging lighter nuclei into heavier nuclei.

Ye Tian wrote on the paper: The most common is the fusion of hydrogen isotopes deuterium and tritium into heavier nuclei such as helium to release energy.Nuclear fusion has two major advantages over nuclear fission.

One is that nuclear fusion energy in the world is far more abundant than nuclear fission energy.

According to calculations, every liter of seawater contains three thousandths of a gram of deuterium, so there are more than 40 trillion tons of deuterium in seawater alone on the earth.

The deuterium contained in one liter of seawater, through nuclear fusion, can provide the energy equivalent to the energy released after burning three hundred liters of gasoline.

The nuclear fusion energy stored on the earth is about 1000 million times of the total nuclear fission energy that can be released by the stored nuclear fission elements, which can be said to be an inexhaustible energy source.

As for tritium, although it does not exist in nature, it can be produced by the interaction of neutrons with lithium, and seawater also contains a large amount of lithium.

It is no exaggeration to say that this is an inexhaustible resource!

of course.

compared to other technologies.

The biggest technical advantage of nuclear fusion is that this thing is quiet and safe.

Because it does not produce radioactive substances that pollute the environment, it is clean.

At the same time, the controlled nuclear fusion reaction can be carried out continuously and stably in a thin gas, so it is safe.

In fact.

Ye Tian looked up some information about nuclear fusion before.

He found that, in fact, there are many ways to achieve nuclear fusion in the world.

The earliest well-known method is the tokamak type magnetic field confinement method.

It uses the powerful magnetic field generated by the strong current to confine the plasma in a small range to achieve the above three conditions.

Although close under laboratory conditions, it is still far from reaching industrial applications.

According to the current technical level, hundreds of billions of dollars are needed to build a tokamak nuclear fusion device "[-]".

For our country, this is naturally not cost-effective.

Ye Tian didn't allow that kind of thing to happen either.

Another way to achieve nuclear fusion is the inertial confinement method.

In inertial confinement nuclear fusion, several milligrams of mixed gas or solid of deuterium and tritium are packed into a small ball with a diameter of about several millimeters.

When the laser beam or particle beam is evenly injected from the outside, the spherical surface evaporates outward due to energy absorption, and the inner layer of the spherical surface accumulates inward due to its reaction.

The reaction force is a kind of inertial force, which makes the gas restraint, so it is called inertial restraint, just like the gas in a jet plane sprays backward and pushes the plane forward, the gas in the ball is squeezed and the pressure rises, accompanied by A sharp rise in temperature.

When the temperature reaches the required ignition temperature.

That is to say, when it takes about several billion degrees, the gas in the ball will explode and generate a lot of heat energy.

This explosion process is very short, only a few picoseconds.

The so-called picosecond is a unit of measurement, and one picosecond is roughly equivalent to one trillionth of a second.

If such explosions occur three or four times per second and continue continuously, the energy released is equivalent to a million-kilowatt power station.

This is the information Ye Tian found.

But although it is so simple in principle, the power that can be achieved by existing laser beams or particle beams is dozens or even hundreds of times worse than what is needed.

Coupled with various other technical problems, inertial confinement fusion is still elusive.

but.

This time.

With 20.00% of the system rewards to control nuclear fusion technology, Ye Tian suddenly discovered.

It seems that some of the previous ideas are possible to realize.

"Got to speed up."

Ye Tian thought for a while.

Speaking to himself.

The main purpose of his visit to Shencheng this time is to make the laser transmitter.

As for this nuclear fusion technology, it is purely a system reward.

He didn't think of it at all.

fortunately.

The reward of the system is 20.00% controllable nuclear fusion technology.

In other words.

This is just the beginning.

thought here.

Ye Tian picked up his cell phone and dialed Jiang Haichao's number.

"Why did you remember to call me?"

Jiang Haichao asked in surprise.

"About the nuclear fusion thing you told me last time, I have a little immature idea."

Ye Tian said calmly.

About 20.00% technology, it is normal to say that it is an immature idea.

"Young is good."

Jiang Haichao laughed: "It's okay to have an idea, I'll write it into a report first and I'll have a look. We don't want to achieve it in one go, and it's okay to take it step by step."

As an old Jianghu.

He is more patient than Ye Tian.

Because Jiang Haichao knew that sometimes a scientific research cannot be completed by one or two generations.

Take the use of nuclear energy as an example.

In the early 30s, the principle of nuclear fusion was deduced.

But five years later.

Nuclear fission, which changed the world pattern, was discovered.

Moreover, the principle of the nuclear fusion reactor is very simple and easy to understand, but its realization was almost impossible for the human technology level at that time.

In the first step, the reactant gas mixture must be heated to a plasma state.

That is, the temperature is high enough to allow electrons to break free from the shackles of the nucleus, and the nucleus can move freely. At this time, it is possible to make direct contact with the nucleus. At this time, a temperature of about [-] degrees Celsius is required.

In the second step, in order to overcome the Coulomb force, which is the repulsive force between the same positively charged nuclei, the nuclei need to travel at extremely fast speeds,

There is only one easiest way to get this speed, and that is to continue heating to 0 .

Takes the Brown Movement to an insane level!

To make the nucleus reach this operating state, a temperature of hundreds of millions of degrees Celsius is required.

Then it is simple, the atomic nuclei of tritium and the atomic nuclei of deuterium directly collide with each other at a great speed, producing new helium nuclei and new neutrons, releasing huge energy.

After a period of time, the reaction body no longer needs to be heated by external energy sources, and the temperature of nuclear fusion is sufficient to continue the fusion of atomic nuclei.

In this process, as long as the helium nuclei and neutrons are removed in time, and a new mixture of tritium and deuterium is input into the reaction body, nuclear fusion can continue, and a small part of the energy generated stays in the reaction body, maintaining a chain reaction, and a large Part of it can be exported and used as energy.

It sounds easy.

But there is a core problem,

That is,

Where is this reaction body with a temperature of hundreds of millions of degrees Celsius placed?

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

This is why there is the emergence of inertial constraint law.

Because that is not a chemical method, but a physical method.

That is the inertial restraint method that Ye Tian knows.

"You are a smart boy, I hope you can come up with new ideas like my teacher."

Jiang Haichao said to Ye Tian.

As everyone knows,

One of the founders of the theory of inertial restraint release is his teacher, Professor Wang, who is a scientist with honor level 0.2.

Hear Jiang Haichao's words.

Ye Tian hesitated for a moment, then said cautiously: "Actually, I'm thinking about using magnetic restraint.

Because the nucleus is positively charged.

Then as long as my magnetic field is strong enough, you won't be able to escape.

If I build a ring-shaped magnetic field, then you can only move along the direction of the magnetic field lines and in a spiral shape, and you cannot run out of my range.

And at a little distance outside the toroidal field, I can build a large heat exchange device.

Because at this time, the energy of the reactant can only be transferred to the heat exchange body in the form of heat radiation, and then use the method we are already familiar with to convert the heat energy into electrical energy. "

???

???

Hearing Ye Tian's words, Jiang Haichao was stunned.

People always like to hear what they like to hear.

But such a person is very difficult to grow.

Because in that case, people are only learning about themselves and can never grow.

That's why people need to listen to harsh things.

As the saying goes,

If you listen, you will be dark, and you will be clear if you listen.

The same principle applies to academic research.

Especially in the field of physics, it is particularly obvious.

If you are a fledgling novice, or a layman with little experience and level.

Maybe I don't quite understand what Ye Tian means.

But Jiang Haichao is different.

As one of the only remaining theoretical physics masters in China.

There is no doubt about Jiang Haichao's level.

to some extent,

There are no more than ten people in the whole country who can understand and understand what Ye Tian is saying.

And among these ten people.

Jiang Haichao's level is undoubtedly the highest.

Precisely because of this.
