The world is studying controlled nuclear fusion technology, which is favored by the scientific community for its low cost and high output.

If the research is successful, how much will the electricity bill be once? How low is the price? Or don't even want any dime?
nuclear fusion is harmful?
In today's era when the nuclear research process is in-depth, people are often "fearing talking about nuclear changes". Taking the Soviet Union as an example, the Chernobyl incident directly endangered hundreds of thousands of people, causing the cancer prevalence rate of local people to remain high.
After entering the 21st century, nuclear power plant leaks occurred in Japan, and a large area of the ocean was polluted by nuclear wastewater.
"nuclear" word has made people feel scared to talk about it
For decades, the nuclear industry has gradually become the object of criticizing . Now the so-called nuclear fusion technology has appeared again, which is naturally unpopular.
In fact, previous nuclear industry leaks were all caused by nuclear fission technology and had nothing to do with nuclear fusion.
On the contrary, nuclear fusion is a completely clean and harmless energy source. The basic principle of
nuclear fusion is that a heavier nuclear and a lighter nuclear fuse together, and this process will burst out with powerful energy.
For example, the neutrons polymerized by two deuterium atoms are nuclear fusion during the fusion reaction of helium-3.
Nuclear fusion reaction principle
Although nuclear fusion can burst out powerful energy, its own fusion reaction is stable, and the half-life of the substance is short. Even after a nuclear leak, the harm caused is much smaller than that of nuclear fission.
Theoretically, after a nuclear fusion leak, it is only necessary to evacuate the leakage center one kilometer range at most.
You should know that after the Chernobyl incident, the Soviet Union officially blocked all 30 kilometers of surrounding areas.
Terrible nuclear shadow
In contrast, nuclear fusion is much cleaner than nuclear fission, and if the constraints on nuclear fusion are not maintained, the reaction will stop and will not cause continuous harm to the environment.
Many people don’t believe that energy with a nuclear word will be so clean .
But that's the case. For example, the main source of light and heat in the universe - star , is heat radiation generated through internal nuclear fusion.
Star structure
People absorb the nuclear fusion radiation of the sun every day on the earth, and it is not necessarily a problem. If the sun is not seen for a few days, people will feel uncomfortable.
Since nuclear fusion is so amazing that it is amazing , will the electricity bill be reduced if the controlled nuclear fusion is successfully developed?
Nuclear Fusion and Electricity Charge
Before discussing this issue, let’s take a look at how strong nuclear fusion is in power generation, and naturally we will know whether the electricity bill can be reduced.
Nuclear fusion reaction principle
130 mg deuterium element per , the energy generated by nuclear fusion is equivalent to the total amount of 300 liters of gasoline burned.
On the earth, seawater has the richest deuterium element content. One liter of seawater contains 30 grams of deuterium. The energy generated by a cubic kilometer of seawater through nuclear fusion is equivalent to the total amount of all oil on the earth.
Oil is still industrial blood
and, according to preliminary estimates by scientists, the content of deuterium in seawater is more than 45 trillion tons.
This 45 trillion tons of deuterium alone can be used by humans for tens of billions of years, and the lifespan of the sun is only 10 billion years.
Therefore, for humans, nuclear fusion is an inexhaustible energy that can’t take . By hundreds of millions of years later, humans have already developed newer and better energy.
Nuclear reactor
At this time, it is difficult to say whether humans are still on Earth.
Judging from the various advantages of nuclear fusion, humans do not seem to have to worry about the future energy field, and electricity prices may even be free.
But in fact, there is no such good thing. The cost of raw material for controlled nuclear fusion for power generation is not high, but the requirements for technology are very strict, and the costs incurred in the process are not expensive.
Nuclear fusion power generation
Now there are only two ways for humans to achieve controllable nuclear fusion. One is to use magnetic constraints to promote the occurrence of controllable nuclear fusion.
The first method requires the construction of a powerful ring magnetic field device . As early as 1950, the Soviet Union built a ring magnetic field device, but the operation of the device requires a stable energy gain factor to control unstable magnetic field devices.
In the next 17 years, the Soviet Union's research on energy factors failed to achieve results.
In 1993, the United States improved the stability of energy gain factor in the control magnetic field, allowing humans to take another step towards controlled nuclear fusion.
Nuclear fusion power generation principle
Currently, the technology of the stable ring magnetic field device studied by humans has matured in the laboratory, but it has never been practiced.
Experts speculate based on the current technical level that if humans want to build a stable ring magnetic field device, they will require at least to hundreds of billions of construction costs.
This is just a preliminary estimate. The costs incurred in the actual process may be higher, and may reach several trillion or even 10 trillion yuan.
Nuclear fusion reactor
Such an expensive cost , no country can easily make this money, not to mention that there is no precedent for success, and failure is also very risky.
The second controlled nuclear fusion requires an ultra-high temperature ignition point to promote atomic fusion reaction.
Nowadays, the maximum temperature that can generate is only 10 million degrees Celsius , and the temperature at the ignition point is at least billions of degrees Celsius, which is a long way to go. Once the
is successfully manufactured, in order to recover the cost, the price of electricity bills may not decrease, but will increase, at least for a considerable period of time.
High-voltage tower transmission
Take Sanxia Hydropower Station as an example. After the construction was successful, the annual power generation reached 100 billion kilowatt-hours, alleviating the tight electricity consumption of in my country. But do you see that electricity bills are dropping? As prices grow, electricity bills are increasing.
However, after recovering the cost, it is likely to be reduced to a certain extent, because our country is an socialist country , and the fruits of national development are shared by the people.
Capitalist country is hard to say, after all, capitalists are all aiming to make money.
However, no matter how much the electricity bill is reduced, cannot be reduced to a few cents . Operation of controllable nuclear fusion reactions and the process of transporting power are a considerable cost.
As for, it is free, that is even more impossible.
In fact, living in China, everyone should be proud, because the price of water and electricity in China is relatively low all over the world.
Three Gorges Hydropower Station produces a large amount of electricity to lower the electricity price
2022 Germany's electricity bill reached 0.543 euros per kilowatt-hour (equivalent to RMB 3.76), and France's electricity price is only 2.86 yuan per kilowatt-hour.
Look at Japan, which has many nuclear power plants, the electricity price of Japan is implemented as a step-by-step electricity price. The initial electricity price after conversion is RMB 1 per kilowatt-hour. If it is above 120 degrees, it will be RMB 1.33 per kilowatt-hour, and if it is above 300 degrees, it will be RMB 1.5 per kilowatt-hour.
In addition, there is also a starting electricity price in Japan: 14 yuan. Even if someone does not use electricity for a month, he has to pay this 14 yuan.
Look at my country again, the average electricity price in my country is 0.8 yuan per kilowatt-hour. In some cities with poor economy, the starting price of the ladder electricity price is 0.5 yuan per kilowatt-hour.
Compared with European countries, my country's electricity price is really cheaper than .
In fact, behind the cheapness is that the national finance is helping the people, trying to lower the electricity price and reduce living expenses, and the same is true for domestic water use.
Therefore, electricity cannot be reduced to a few cents, and everyone should also understand and tolerate .
The significance of controlled nuclear fusion
The biggest feature of controlled nuclear fusion is its cleanliness and sustainable development. Most new energy sources, such as wind energy, water energy, etc., have uncontrollable factors .
Wind energy depends on the sun's heating of the atmosphere, and water energy is even more exhausted.
Many rivers in my country rely on icebergs to replenish supplies. In the case of global climate warming , the melting speed of icebergs exceeds the freezing speed, and the storage of ice and snow decreases . Over time, the river water sources will become less and less, and the water energy value of rivers will be greatly reduced.
There is no need to say much about solar energy, it is entirely based on the face of the sun to generate electricity.
, and controllable nuclear fusion is a technology that can truly allow humans to independently master endless energy , and is called "artificial sun".
my country is leading the world in the development of controlled nuclear fusion. The EAST reactor is the most advanced controlled nuclear fusion reactor in the world. I believe that the EAST reactor will lead my country's energy to a new height.
