"Master, this battery-binding power device can be used for nuclear fusion." [Four-Armed King Kong] reminded.
When Wu Siyuan heard this, his eyes lit up.
Nuclear fusion, also known as nuclear fusion, fusion reaction, fusion reaction or thermonuclear reaction.
The nucleus refers to atoms with small mass, mainly deuterium. Under certain conditions (such as ultra-high temperature and high pressure), only under extremely high temperature and pressure can the electrons outside the nucleus be freed from the shackles of the nucleus, allowing the two nuclei to
They attract each other and collide together, causing the nuclei to fuse with each other to generate new nuclei with a heavier mass (such as helium).
Although neutrons have a relatively large mass, since neutrons are not charged, they can escape from the constraints of the atomic nucleus and be released during this collision. The release of a large number of electrons and neutrons represents a huge energy release.
This is a form of nuclear reaction.
There is huge energy in the nucleus, and changes in the nucleus (from one type of nucleus to another) are often accompanied by the release of energy.
Nuclear fusion is the opposite form of nuclear reaction to nuclear fission.
At present, uncontrollable nuclear fusion can already be achieved.
But what scientists want to achieve is controllable nuclear fusion.
Once successful, nuclear fusion could become the energy source of the future.
Nuclear fusion fuel reserves are abundant, the energy released by the reaction is several times more than that of nuclear fission, and the reactants are almost pollution-free. There is no doubt that nuclear fusion is an ideal clean energy source.
There's just one problem. Fifty years ago, scientists said that nuclear fusion would be possible within fifty years. Fifty years later, scientists are still saying the same thing.
Just because the requirements for controllable nuclear fusion are a little too high.
Because the conditions for nuclear fusion reactions to occur are extremely harsh, the reaction process must be coordinated with extremely high temperatures and pressures.
The difficult problem in controlling nuclear fusion is to confine the plasma.
When fusion occurs, extremely high energy is produced, so nuclear fuel cannot be stored in conventional containers, as everything will be melted by the high temperature.
To constrain the plasma, it can only be carried out without contacting the container. The current constraints include inertial constraints, magnetic constraints, and gravitational constraints.
The gravitational constraint refers to the sun.
Because the sun is undergoing nuclear fusion all the time, it produces light and heat.
And because it has a very large mass, the strong gravitational internal pressure offsets the huge outward pressure generated by nuclear fusion, forming a pressure balance.
On the one hand, this pressure balance prevents the material from exploding, and on the other hand, it forms a strong and stable internal pressure so that nuclear fusion can occur.
Unless the sun explodes, this reaction will continue until the sun cannot survive and becomes another kind of star.
This gravitational constraint method cannot be accomplished by humans, so it is only for reference.
The current main research direction of mankind is still inertial constraints and magnetic constraints.
Inertial constraints!
According to Newton's second law: F=ma, when an external force F is applied to an object of mass m, the object will acquire an acceleration a. The inertial constraint is to use multiple ultra-high-power lasers to align the small balls encapsulated with nuclear fuel and emit lasers at the same time. Small
The surface of the ball instantly vaporizes outwards, creating a reaction force on the inside, violently squeezing the nuclear fuel. Because the action time is very short, the nuclear fuel has been pushed together to undergo nuclear fusion before the nuclear fuel can gain enough speed to take it away.
Of course, there are many difficulties at the moment.
Magnetic confinement is relatively simple, because the high-temperature plasma produced by nuclear fusion has a temperature of hundreds of millions. Any object that encounters this temperature will be directly vaporized. When a container cannot be found, scientists thought that since protons are positively charged
, then a magnetic field can be used to restrict the movement of protons and avoid contact with the container.
Scientists have therefore invented many devices. Among them, one device with particularly good results is called "Tokamak".
But it still has not helped mankind achieve the goal of controllable nuclear fusion.
And now, the dawn appears on the [Ningyun Gas] that Wu Siyuan picked up from Doraemon.
Wu Siyuan thought hard and never thought that electromagnetic restraint force field equipment could be developed from a black technology product like [Ningyun Gas].
Moreover, [Four-Armed King Kong] also told him that it could be used in nuclear fusion.
[Four-Armed King Kong] has said this, which means that the feasibility is very high.
Wu Siyuan imagined that once controllable nuclear fusion is first developed in the real world, the impact on the world will be earth-shaking.
He will also be able to harvest unimaginable influence and energy.
It's just that... when he promotes it on a large scale, he must take confidentiality measures to prevent the technology of controllable nuclear fusion from leaking out. Wu Siyuan thought in his heart.

Wu Siyuan said to [Four-Armed King Kong], "Continue studying."
Then consciousness returns to the real world.
This Doraemon world makes Wu Siyuan feel very awkward, mainly because of the existence of the space-time police, which prevents Wu Siyuan from doing things at will.
But the harvest is indeed extraordinary.
Wu Siyuan has only obtained [Ningyun Gas] from Doraemon so far, but it is only a preliminary study on [Ningyun Gas], and it is expected to create an electromagnetic binding power device.
If we get other magical props for research, I don’t know what black technology we can come up with!
Like the [Bamboo Dragonfly], if Doraemon hadn't taken away the charger, Wu Siyuan would have definitely taken it back for research.
Several key technologies of [Bamboo Dragonfly], such as anti-gravity devices and brain-computer connection, Wu Siyuan has related technologies, obtained from the world of [Godzilla].
But the technologies he obtained are far from as advanced as [Bamboo Dragonfly].
How big are the devices produced by Wu Siyuan's technology and how restrictive are they? But what about the [Bamboo Dragonfly]?
The technological generation gap here is unimaginable to Wu Siyuan. It may be that the technological gap between the first generation of computers and current computers is as big as that.
Wu Siyuan can still understand these technologies.
But many of Doraemon's technologies are difficult for Wu Siyuan to understand.
For example, [Time Machine]!
Wu Siyuan is especially interested in Doraemon’s [Time Machine].
It would be really amazing if Wu Siyuan could get Doraemon's [Time Machine] for research and have the opportunity to master the ability to travel through time!
I'm afraid Wu Siyuan could become a [Pseudo-God of Time] if he went to some Western fantasy world!
[The God of Time] has a high level of prowess in various Western fantasy worlds. At the very least, he is a powerful god or the main god.
That’s so cool!
Of course, Wu Siyuan also knows that this is a difficult thing.
If you want to use a "time machine" to research the "time travel technology" behind it, it is really not easy.
This is equivalent to primitive people looking at a mobile phone, completely unable to start or understand.
If Wu Siyuan can obtain scientific research results related to the future world, then there will be a glimmer of hope.
With such thoughts in mind, Wu Siyuan fell into sleep.
