I Have A Super USB Drive

There are three forms of nuclear reactions known to mankind, namely nuclear fission, nuclear fusion and nuclear decay.

Among them, nuclear fission and nuclear fusion can provide energy for human beings. According to Einstein's mass-energy equation E=mc^2, as long as there is a mass attenuation before and after the nuclear reaction, a certain amount of energy is released.

The so-called nuclear fission is the production of energy through mass loss caused by the fission of heavy atoms.

Nuclear fusion, on the contrary, uses light atomic nuclei to gather together to produce heavier atomic nuclei, and mass attenuation occurs, thereby generating energy.

The reason why nuclear fusion is better than nuclear fission is not only because the energy released by nuclear fusion is greater, but more importantly, the raw materials for nuclear fusion can be extracted from seawater. Deuterium is abundant in the earth's seawater, up to 400,000. 100 million tons, if all used in fusion reactions, the energy released will be enough for humans to use for tens of billions of years.

The common nuclear fission reaction raw material-uranium 235 reserves are scarce, and the nuclear waste produced will affect geology for hundreds of years. Therefore, nuclear fission cannot be compared with nuclear fusion whether it is reserves or clean and safe.

Therefore, nuclear fusion energy is an infinite, clean and safe new energy that countless people yearn for.

Of course, nuclear fusion does not only refer to deuterium-tritium fusion. As long as it is an element smaller than iron in the periodic table, nuclear fusion can actually occur. The reason why humans choose only tritium and deuterium as fusion materials is because they have nuclear fusion. The conditions are the simplest.

Compared with other elements, the hydrogen isotopes, deuterium and tritium nucleus, have only one proton. The fusion reaction between tritium and deuterium only needs to overcome the repulsive force between the two protons, while other elements need to overcome a bunch of protons. The difficulty of the previous repulsive force is not the same.

Now that he determined the next route to overcome nuclear fusion, Chen Chen returned to his office and found out the nuclear fusion reactor technology on the plane of "Elysium".

However, after a few glances, Chen Chen frowned. He has been specializing in medicine and biology. Although he has a slight understanding of nuclear physics, it is limited to the surface, and at best it is more than ordinary people know.

So Chen Chen looked up and said, "X, immediately sort out a document that can quickly understand nuclear physics."

With that, he took out the chewing gum tin box, opened it gently, and suddenly an NZT-48 flew into the mouth.

Then Chen Chen's expression became clear in vain.

At the same time, Xiao X quickly sorted out a piece of information about nuclear physics from shallow to deep, so Chen Chen looked through the technical documents provided by Xiao X, and at the same time confirmed the nuclear reactor on the plane of "Elysium". data of.

This time, Chen Chen could almost understand it.

"Unexpectedly, there is more than one nuclear fusion reactor technology used in the plane of "Elysium".

Chen Chen smiled and opened the second drawing, "Is the inertial confinement nuclear fusion reactor and the magnetic confinement nuclear fusion reactor? It's incredible..."

"In fact, the mainstream of the continents of the Earth Federation is also these two."

Xiao X explained, "But if these technologies are subdivided, they can be divided into multiple branches, and there are even similar jokes circulating on the Internet..."

"What joke?" Chen Chen couldn't help asking.

"It divides the various fusion technology into the nine camps of DND in a straightforward and intuitive way. Each camp has a anthropomorphic speech."

Little X explained, "For example, a star simulator that represents'lawful goodness', the anthropomorphic speech is: My heart and my walk are calm as stars, and everything I do is steady."

"And the neutral and kind magnetic realm, the anthropomorphic statement is: there is no magnetism to leak, there is no helium-3 to burn, because I will not be a reactor!"

"And the chaotic and kind Tokamak: I'll tell you the plasma current again, you don't want to do anything more!"

"In addition, there are spherical tokamak representing lawful neutrality, field anti-constrained tokamak representing absolute neutrality, and magnetized target fusion representing chaotic neutrality, etc..."

The more I talked about the latter, the more excited Xiao X's tone became, "And the most funny is the laser fusion technology that represents chaos and evil-its anthropomorphic statement is: I TM shot!"

"..."

Chen Chen looked up in amazement, "X, I heard you right, are you in GHS?"

"I, I don't have..."

Little X suddenly hesitated, "What kind of yellow is this? Humans are called yellow. I'm an intelligent life... can I be called yellow in the matter of intelligent life? I'm a stalker, playing nuclear physics. A terrifying stalk!"

Chen Chen shook his head and didn't care about this issue. He just remembered Xiao X's increasingly humane changes in his heart, and said again, "Now I basically understand why the development of nuclear fusion is more difficult than nuclear fission. Many, in fact, because the physical laws of the two reactions are different."

"The mass of nuclear fission nuclei is relatively large, and it is unstable. Therefore, as long as the environment of normal temperature and pressure can realize fission reaction, nuclear fusion is different. To overcome the huge electrostatic repulsion between nuclei, there is not enough energy or special When the environment breaks this critical point of repulsive force, it will not be able to fuse atomic nuclei together."

"So, the key is to create a high-pressure and high-temperature environment?"

"Yes, it is."

Little X replied, "The most common nuclear fusion reaction in the universe is the sun. Because of its own mass, the sun can make the core form an ultra-high pressure of 200 billion atmospheres, plus a temperature of 15 million degrees. Fuse hydrogen atoms into helium atoms."

"But if humans want to achieve this same nuclear fusion on the earth, the ultra-high pressure conditions are completely impossible to achieve. Therefore, today’s nuclear fusion devices need to work hard at high temperatures, and they need to change the core temperature from the sun’s core to 1500 The 10,000 degrees should be raised to more than 100 million degrees."

"The simplest and most direct method is to use a large number of energized coils to form a ring along the ring to generate a strong magnetic field to form a magnetically confined nuclear fusion reactor, and this device that can generate a sufficiently strong ring magnetic field is Called the'tokmak device'."

"Another inertial confinement nuclear fusion reactor uses a mixture of deuterium and tritium in milligrams as a unit to fill a small ball with a diameter of a few millimeters, and inject a laser beam uniformly from the outside. The spherical surface absorbs energy and moves outward. Evaporation, and by its reaction, the gas in the ball is squeezed and the pressure rises, accompanied by a sharp increase in temperature. When the temperature reaches the required ignition temperature, the gas in the ball will explode and produce a lot of Heat!"
