Is controlled fusion the core of the future?

Today, when the earth's resources are gradually being consumed, solar nuclear energy has become one of the main resources of mankind in the future. Controlled nuclear fusion technology is the mainstream technology that can control nuclear energy. It will also be the core of the future.

Controlled nuclear fusion will become the core of human development in the future, no matter what we do in life, we can't do without energy, if there is controlled nuclear fusion, human beings will not worry about the problem of energy shortage.

It should become the core of the future, but nuclear fusion technology is difficult and should have a high enough temperature, so there are certain limitations for the time being, but at present, the solar core has become a resource for mankind, so there is no need to worry about nuclear fusion will naturally become the core of the future

Mastering nuclear fusion technology is the future development direction of mankind on the use of nuclear energy, but it is not the core of the future, because nuclear energy alone is not enough to enable human beings to generate large kinetic energy in a small volume, because even if the reaction of nuclear energy is controllable, its energy supply is still limited.

Controlled nuclear fusion technology is not a core of the future, because this nuclear energy has many limitations. And it's going to change a lot, and you can't use it for everything.

Controlled nuclear fusion will be a science and technology for mankind to move toward cosmic civilization.

Can the reactor ratio be maximized? Has nuclear fission found the safest way? Is the heat and residue treatment synchronized?

See if the theory is true and whether it is a **.

First of all, the subject is discussing the importance of controlled nuclear fusion, that is, what the implications are for the future:

1. Mastering controllable nuclear fusion can obtain more powerful and stable energy. Controlled nuclear fusion uses the principle of nuclear fusion, through particle collision, the energy obtained is very huge, and stable, the sun is a living example, the solar energy is strong and stable, if human beings have this technology, the future can be rapid development in many fields, once human energy becomes strong and stable, science and technology will definitely advance by leaps and bounds, and the energy level used by scientists will be greatly improved.

2. Mastering controlled nuclear fusion can improve the earth's environment. Due to the access to the efficient clean energy produced by nuclear fusion, we can use less, or even no longer use the earth's polluting energy, such as gasoline, oil, can effectively reduce the emission of carbon dioxide and harmful gases, which is simply good news for the earth's ecological environment, human beings can also take a more sustainable development route, but also solve the greenhouse effect, ozone layer hole and other thorny problems, in short, controllable nuclear fusion brings clean energy, pollution-free, this is the top priority.

3. Master controllable nuclear fusion and make efficient use of the earth's resources. The earth's resources needed for controlled nuclear fusion are water, the earth's oceans account for 71% of the earth's area, and water resources can almost be said to be inexhaustible and inexhaustible. Under this efficient development trend, the earth will accumulate more other resources for human use in the future.

4. Master controlled nuclear fusion and change the world pattern. Due to the change of energy, the earth's energy pattern will be cleansed, the snatching of resources due to war will no longer occur, and the reduction of war will make the people of the world more harmonious and united. With the joy of the spirit and the rapid development of science and technology, the whole earth will be greatly sublimated, and the list of such problems is simply endless.

In short, the realization of controllable nuclear fusion is of great significance, and it will have a huge impact on the future survival of mankind, and the improvement of energy will not only affect human society, but also change the ecological system of the entire earth, and the above four points are only relatively important, objective and intuitive. Thank.

If controlled nuclear fusion is achieved, humans can use nuclear energy as they please, which can get rid of dependence on fossil energy and reduce air pollution and the greenhouse effect. Existing nuclear power plants will also be withdrawn from the stage of history.

The importance is that nuclear fusion can be controlled, nuclear fusion can be better applied, nuclear fusion can be better developed, nuclear fusion can be better used, and better use in scientific research.

It has a particularly important role in releasing energy through nuclear fusion, which can improve the application rate, drive the development of new energy, and then make good use of the sun's energy and save resources.

The meaning of energy and the environment.

Controlled nuclear fusion, under certain conditions, the speed and scale of nuclear fusion are controlled by a lack of slip to achieve a safe, continuous and stable nuclear fusion reaction with energy output. There are forms of laser confinement nuclear fusion, magnetic confinement nuclear fusion, etc. It has the advantages of sufficient raw materials, excellent economic performance, safety and reliability, and no environmental pollution.

Due to the extremely high technical difficulty, it is still in the experimental stage.

There are about three main methods of controlled nuclear fusion: gravitational confinement, inertial confinement, and magnetic confinement.

Nuclear fusion is the process by which two lighter nuclei merge into one heavier nucleus and release energy. The easiest fusion reaction in nature is the fusion of deuterium and tritium, isotopes of hydrogen, which has been going on on on the sun for 5 billion years. Controlled nuclear fusion is commonly known as artificial sun, because the principle of the sun is nuclear fusion reactions.

Nuclear fusion reactions rely mainly on hydrogen isotopes. Nuclear fusion does not produce the long-term and high level of nuclear radiation that occurs in nuclear fission, does not produce nuclear waste, and certainly does not produce greenhouse gases, and basically does not pollute the environment) People understand that thermonuclear fusion began with the hydrogen bomb. Scientists hope to invent a device that can effectively control the process of the "hydrogen bomb**" and allow the energy to continue to output steadily.

Is nuclear fusion controllable as follows:

At present, human beings cannot control nuclear fusion, and controllable nuclear fusion is generally recognized by experts in the nuclear field, but the realization of artificial controllable nuclear fusion is not at the same level as controllable nuclear fission, and many core technologies and equipment of controllable nuclear fusion are still being gradually explored.

The main types of controlled nuclear fusion:

Sun-gravitational confinement fusion, everything on Earth relies on the sun's constant energy to sustain its development.

Hydrogen bomb - inertial confinement fusion hydrogen bomb is an artificially realized, uncontrollable thermonuclear reaction, and it is the only way to obtain fusion energy on a large scale on earth by artificial methods, but it must be ignited by fission, so it is essentially a mixture of fission and fusion, and the fission energy and fusion energy in the total energy are roughly equal.

The hope of controlled fusion – magnetically confined charged particles (plasma) are bound by the Lorentz force in a magnetic field that moves around the magnetic field lines and are therefore confined in a direction perpendicular to the magnetic field lines. At the same time, the plasma is also heated by electromagnetic fields. Since it is not yet possible to achieve a magnetic field strength of more than 10 t, the magnetically confined high-temperature plasma must be very rare.

Nuclear energy includes two main forms: fission energy and fusion energy.

Fission energy is the huge energy that the atoms of heavy metal elements release through fission, and it has been commercialized. Because the uranium and other heavy metal elements required for fission are scarce on the earth, and conventional fission reactors produce long-lived and highly radioactive nuclear waste, these factors limit the development of fission energy. Another form of nuclear energy is fusion energy, which has not yet been commercialized.

Deuterium is abundant in the Earth's seawater, up to 40 trillion tons, and if all of it were used for fusion reactions, it would release enough energy for humans to use for tens of billions of years, and the reaction product would be non-radioactive contaminated helium.

In addition, because nuclear fusion requires extremely high temperatures, if there is a problem in one part of the process, the fuel temperature drops, and the fusion reaction will automatically stop. In other words, the fusion reactor is a subcritical reactor, and there will never be an accident similar to the Chernobyl nuclear (nuclear fission) power plant in the former Soviet Union, and it is safe. Therefore, fusion energy is an unlimited, clean, and safe new energy source.

Nuclear fusion is uncontrollable.

Controlled nuclear fusion is the process of causing two light atoms to collide in a high-temperature and high-pressure environment to coalesce into a single heavy atom, and in the process there is a loss of mass, and the lost mass is released in the form of energy. From the mass-energy equation, energy is equal to mass multiplied by the speed of light squared, so a small loss of mass will be converted into a huge amount of energy.

The raw materials needed for controllable nuclear fusion, some people say that it is helium 3, deuterium and helium 3 can carry out nuclear fusion reactions, and the moon has very rich helium 3 resources, but the problem is that the technical difficulty of this Kai potato seed reaction is relatively high, it belongs to the second generation of nuclear fusion, and what is being studied now is the first generation of nuclear fusion with relatively low technical refiring difficulty, and the raw materials used are two isotopes of hydrogen, deuterium and tritium.

The principle of synthetic tritium:

In principle, it is not too difficult to synthesize tritium, which can be obtained by bombarding lithium with neutrons, but in reality, if you want to make synthetic tritium, you can use gas-liquid catalytic exchange technology and special electrolysis technology. In fact, it is not difficult to synthesize tritium, the difficulty lies in consumption and cost.

The study of controlled nuclear fusion is to obtain energy, and the process of making tritium must consume energy, and the later confinement fusion reaction also consumes energy, although there are many artificial synthesis and manufacturing of tritium leakage technology, but the cost is very high, and it is still difficult to produce it in large quantities, which is also a difficulty to face in the process of controlled nuclear fusion research.

Controlled nuclear fusion could free humanity from the energy crisis once and for all.

Based on the current energy consumption of human beings, once controlled nuclear fusion is realized, energy will no longer be something that needs to be saved.

Taking helium-3, a raw material that can be used for nuclear fusion, as an example, every 100 tons of helium-3 can meet the energy needs of all mankind for a year of shortage, and the content of helium-3 in the soil on the surface of the moon is more than one million tons. In addition to helium-3, the isotopes of hydrogen tritium and deuterium can also be used for nuclear fusion. Frankly.

Humans can now use nuclear fission to generate electricity, but the resources of nuclear fission on the earth are very limited, according to relevant data, the current proven raw materials that can be used as nuclear fission on the earth are only enough for human beings to use for a few decades. In contrast, there are far more resources for nuclear fusion on Earth, with 40 trillion tons of deuterium (the isotope of hydrogen is lacking) in the Earth's seawater, and if fully utilized, one kilogram of deuterium fusion reaction can produce almost 100 million kilowatt-hours of electricity. And that's not even counting the other widely available nuclear fusion resources in the universe, such as the moon's staggering reserves of helium-3.

If humans could control the energy of nuclear fusion at will, we could achieve complete self-sufficiency, even without relying on the sun

What about controlled nuclear fusion, what exactly is it, and this resource is in the beginning.
