Hand rubbing nuclear fusion live in the wilderness

Chapter 351
Staying in the control room, Han Yuan chatted with the audience in the live broadcast room while watching the log files flowing on the screen.

If there is no accident, it is certain that the space shuttle will go to the sky, but such things as satellite deployment, orbit adjustment and angle adjustment may not be executed smoothly.

He could still see something in the control room through the pictures transmitted back synchronously by the space shuttle and the reconnaissance communication satellite.

If the satellite fails to enter orbit, he can use the space shuttle as a transfer station on the ground to make command adjustments and supplements.

As long as the satellite can receive signals normally, the functional chip carried can function normally.

Through the function chip, he can call and write the control program in the control room, and adjust the height and angle of the satellite slightly.

This is the second hand, and it is his means to increase the success rate of satellite orbiting and normal operation.

Of course, KRW does not want to use this kind of backhand, because in this situation, the failure rate of satellites entering orbit is as high as 80.00%, and the effect of ground adjustment is not high, it can only give people a little hope. .

Besides, KRW also wanted to feel the sound of "satellite orbiting successfully" at the first time.

This kind of joyful achievement and pride cannot be replaced by other things.

More than two hours is quite a long time for Korean Won who can stare at the log files on the display screen with nothing to do.

Fortunately, the sand sculpture netizens in the live broadcast room can relieve him from his fatigue. This will be not long after the satellite launch, and the topics discussed by netizens are basically related to this.

[Do you think the anchor's satellite can be successfully launched into the sky? 】

【God is definitely fine, I don’t know if I can enter orbit (dog head)】

[I remember that satellite launches are very troublesome, but it feels so easy to come to this anchor. 】

【Simple?You don't even look at how much black technology is contained in the satellite just launched into the sky. 】

[You said that the space shuttle built by the anchor can carry people? 】

【it should be OK? 】

[Upstairs you should ask, can this space shuttle fly out of the solar system! 】

[Space Shuttle, when will our country have one? 】

[The anchors have been created, and we can also copy them. If they can carry people, it will be easy to go to space in the future. 】

【Are you here to provide liquid xenon?The last time it consumed four or five tons, or two or three billion, it was not as good as traditional fossil fuels. 】

[Hey, why is this thing copying it?The space shuttle has been proven to be unreliable. Look at Midi, one of them was launched and one was lost, and the astronauts were damaged. Now the space shuttle has been sealed up. 】

[I am more concerned about when this anchor will make a nuclear bomb, or when he will get out the nuclear fusion technology. 】

Looking at the barrage of these discussions, Han Yuan thought for a while and said, "This space shuttle consumes a lot of liquid xenon working fluid."

"But it's not impossible to improve."

"Do you still remember the base that I discovered by flying around the world with a Lero delta aircraft?"

"In the Taishan base, there is a controllable nuclear fusion power generation device. If it is miniaturized, it can be installed on the space shuttle to greatly reduce the consumption of working fluid."

"Regarding this aspect, if there are no accidents, we should be able to meet you in the next live broadcast."

Hearing this, the audience in the live broadcast room were immediately stunned, staring at the live broadcast room with wide-eyed eyes, a little in disbelief.

[Hold the grass!Is controlled nuclear fusion coming? 】

[The next live broadcast will be two years away. 】

[This live broadcast has been live for three years, and it has been a year and a half, only a year and a half. 】

[I didn't expect to see controllable nuclear fusion in my lifetime! 】

【Brilliant! 】

[After controllable nuclear fusion comes out, interstellar travel will not be far away, I really want to visit other planets. 】

[Electricity prices have plummeted, and those local tyrants in the Middle East will be miserable. 】

[They have been miserable for a long time. When lithium-sulfur batteries and thin-film solar panels came out, the price of oil was cut in half. 】

[The worst thing should be coal. Thermal power consumes so much coal every year, and a lot of it will be used up after one and a half years. 】

[Fuel car: I just cry and don't speak. 】

[Thermal power generation is boiling water, and controllable nuclear fusion is also boiling water, just a more advanced method. 】

[I remember that I saw it in a scientific research report before. It seems that the efficiency of the use of controllable nuclear fusion power generation is not high. The high temperature of hundreds of millions of degrees is wasted, which will cause a lot of thermal radiation pollution. 】

[No matter how high it is, it is lower than coal power generation. 】

[That’s not necessarily true. At present, the thermal efficiency of nuclear power plants in the world is much lower than that of ordinary thermal power plants, about 30%, while ordinary thermal power plants can reach 40-50%, and the controllable nuclear fusion is not higher than that. where to go. 】

[Don't talk, this kind of thing is nothing to the anchor, it uses controllable nuclear fusion, I don't believe it will boil water. 】

[Indeed, boiling water is not a good way to use heat. 】

[Didn't the anchor say that there is a controllable nuclear fusion power supply device at the base on Mount Tai?What is used in that? 】

In the live broadcast room, there was a lot of discussion.

Although they knew that if the live broadcasting room continued, the controllable nuclear fusion technology would appear sooner or later, but no one would have thought that this day would come so soon.

It is only a year and a half away from the next live broadcast.

In a year and a half, will controlled nuclear fusion be available?
Especially the people from various countries who were in the live broadcast room immediately, after hearing the news, they were excited at first, and then panicked as if they remembered something.

This is destined to be another news that will be on the hot search.

After so many years of live broadcasting, most of the viewers in the live broadcast room, including scientists from various countries, have a kind of confidence in Korean won.

The most important thing is that the other party has realized what they said from the beginning to the end, including various black technologies.

Although it is not clear how high the technical level of this anchor is, in the eyes of most viewers, controllable nuclear fusion is definitely not a hindrance.

Even in the eyes of the opponent, controllable nuclear fusion is just like firewood to human beings. It is a completely inconspicuous, primitive and backward energy supply equipment.

Other countries don't talk about it, but Hua Guo knows it.

The ruins discovered in the Shennongjia Scenic Area two years ago allowed Huaguo to provide full information on controllable nuclear fusion thermoelectric energy conversion.

In the Shennongjia Scenic Area, there is a set of special nuclear power generation device. According to human definition, this special nuclear power generation device belongs to "nuclear fission power generation".

But the power generation material it uses is not the common 'uranium' or 'plutonium', but another radioactive element 'curium'.

'Curium' is a metallic element with atomic number 96 and element symbol Cm, which is a radioactive 'artificial' element.

Its radioactivity is very strong. If it is placed in the dark without a light source, it will sparkle and become its own light source.

This element has no elemental or compound mineral deposits on the earth, that is to say, it is unnatural and can only be synthesized artificially, which belongs to man-made synthetic substances.

And the plutonium contained in the white mist that was leaked before is one of the raw materials used to make 'curium'.

'Curium' can be produced by bombarding plutonium atoms with helium nuclei. This is the main source of curium in the Shennongjia base, and it is also the reason why radioactive plutonium elements leaked and caused casualties after the base stopped operating.

Of course, although the use of curium as an energy source is relatively rare, it is not uncommon among human beings, and some satellites also use this material as energy source.

The mention of this has something to do with the thermoelectric conversion system used in this base.

The Shennongjia base uses nuclear fission power generation, but the thermoelectric conversion system it uses is a radioisotope thermocouple generator that has not been developed by humans.

This kind of radioisotope thermocouple generator has a much higher utilization rate of heat energy than boiling water.

At present, human society’s utilization and assumptions of controllable nuclear fission power generation and controllable nuclear fusion power generation are still the same as nuclear power generation. A set of thermal cycle devices is needed to convert the heat energy of fission and fusion into electrical energy, and then use it.

And there are some laws of physics involved.

For example, the most common second law of thermodynamics tells everyone that with human technology, it is impossible to take heat from a single heat source and convert it into useful work without causing other effects.

However, no matter whether it is controllable nuclear fission or controllable nuclear fusion, what is provided is a single ultra-high temperature heat source.

But to utilize this ultra-high temperature single heat source, it is bound to be accompanied by the loss of energy.

It is a pity that even in the 21st century, human beings have not made any waves in thermal power generation.

A way to directly use thermal energy with ultra-high conversion and utilization rates has also not been explored.

The most commonly used thermoelectric conversion is still a heat engine.

That is to say, various machines that use internal energy to do work, such as steam turbines and internal combustion engines.

However, the thermoelectric conversion of the heat engine has a limit, and the loss of heat is also very large.

For ordinary thermal power plants, the thermoelectric efficiency can reach 40.00% to about [-]%.

This is almost the limit of mankind's current conversion of a single heat source.

The power generation devices used in the controllable nuclear fission power generation developed by various countries are also based on the "Carnot cycle" heat engine power generation.

Therefore, for ultra-high temperature nuclear fission power generation, the efficiency of high temperature use is not high, and a large part of the heat is wasted.

And this is also a problem that controllable nuclear fusion will encounter later, and it is a problem that power generation devices based on the Carnot cycle theory will inevitably encounter.

Of course, relevant scientists must have corresponding research and theories on this issue.

But it is still a pity that no good thermoelectric conversion method has been found so far.

Whether it is thermoelectric power generation or thermionic pile power generation, its thermoelectric conversion efficiency is terribly low.

For example, it sounds very high-tech, and it is also used in thermionic reactor power generation on nuclear-powered submarines in the United States and Lao Maozi, and its efficiency is only about 5.00%.

Compared to a heat engine, it's terribly low.

For current humans, it is undeniable that boiling water is still the most efficient way.

If a more efficient way than boiling water can be found, the power generation efficiency of controlled nuclear fission alone can be improved by a large level.

Although for Huaguo, which is laying a large number of LaGaSi solar thin film power plants, nuclear power plants are not so important anymore.

But it does not mean that other countries also have such capabilities.

Especially in some countries with small land area but developed economy, in addition to purchasing electricity from other countries, nuclear power plants are still a very good way of generating electricity.

Even in Huaguo, if the efficiency of thermoelectric conversion can be improved, the nuclear power plant will not necessarily be abandoned.

After all, not all places can build a photovoltaic electric field. It not only needs to occupy a large amount of land, but also has strict requirements on the environment.

In addition, ultra-long-distance power transmission, light pollution caused by photovoltaic electric fields, etc., are very troublesome things.

If the thermoelectric conversion efficiency is improved, nuclear power plants are still an excellent way of generating electricity.

Just like today's Huaguo, after obtaining the Shennongjia base and obtaining a lot of scientific and technological information from it, the major nuclear power plants that were originally planned to shut down not only did not shut down, but there were plans to open new nuclear power plants.

Because there are two key technologies in the Shennongjia base that can solve the troubles caused by nuclear power plants.

One is a white mist that can absorb radioactive elements.

After more than a year of research, the Chinese Academy of Sciences has thoroughly understood this material, and has initially achieved the ability to produce and develop it.

And this white mist can be used to deal with nuclear waste generated by nuclear power plants.

Another technology is this 'radioisotope thermocouple generator'.

It can use the ultra-high temperature generated by nuclear fission and nuclear fusion to generate electricity, and its thermoelectric conversion efficiency can reach about 80.00%.

It is far superior to boiling water, temperature difference power generation and thermionic stack power generation.

This technology has greatly improved the cost and efficiency of nuclear power plant power generation.

Coupled with the fact that there are ways to deal with the extremely troublesome nuclear waste problem, nuclear power plants have actually become a very good way of supplying electricity.

Therefore, Huaguo's customized plan has been revised all the time.

From the beginning of preparing to build large-scale photovoltaic power generation to gradually shutting down nuclear power plants, wind power plants, etc., and then stopping later, and starting to shut down thermal power plants,

Although the transformation of each step is troublesome, it represents the progress of technology.

But now, it's even more troublesome.

The anchor in this live broadcast room said that he may demonstrate the technology of controllable nuclear fusion in the next live broadcast.

This is very painful.

They have just spent a lot of manpower and material resources to lay a large photovoltaic field in the northwest desert, and they are preparing to intensify their efforts to continue.

With your backhand, you have completely changed the technique.

Don’t want the photovoltaic field we laid out?Don't continue to do it?
After all, compared with controllable nuclear fusion, the laying and maintenance of photovoltaic electric fields are more troublesome and occupy a larger area.

Controlled nuclear fusion is really going to be realized, and building one in a province can almost supply the power supply of the entire province.
