Chapter 451: A new stage of nuclear fusion research, the masses: I hope to see it in my lifetime!
Wang Hao does not want to take over the moon landing and round trip trajectory correction project.
One is because the research is too complicated.
If it is a direct mathematical problem, there is no problem in spending a few days to help with research, but the moon landing plan is very large. The calculation of the spacecraft trajectory involves many problems and was completed by dozens or hundreds of scientists.
.
This complex problem cannot be solved in a short time.
In addition, the income is too low.
Dozens or hundreds of scientists worked together to calculate the results. Even though there were many approximate calculations along the way, the approximate and precise values were definitely very close.
He took over the research and spent a lot of energy to correct the trajectory. Compared with the original plan, it would not gain much.
So Wang Hao suddenly thought of a good idea, "Teacher Zhao, there's no need to bother at all. You just need to replace the solar panels with higher performance."
This method made a few people who came here laugh at the corners of their mouths.
Yuan Zhifang smiled bitterly and said, "Academician Wang, of course we hope to have solar panels with higher performance..."
"There is no problem!"
"The solar panels we use are already the most advanced, and are more efficient than those used on the space station."
"Oh? Tell me."
Wang Hao became interested.
There happened to be a researcher who was familiar with solar panel technology, named Cui Heping. He said, "We use triple-junction gallium arsenide panels."
"Triple-junction gallium arsenide solar panels are currently the most advanced panels with the highest conversion efficiency in the world. For example, our space station uses flexible triple-junction gallium arsenide panels, with a photoelectric conversion efficiency of 30%. Four of them
The total area of solar panels is 134 square meters, and the power supply efficiency exceeds 100 kilowatts."
"In recent years, triple-junction gallium arsenide battery panel technology has improved again. The photoelectric conversion rate of the battery panels used in my lunar module exceeded 31%, reaching the current bottleneck of mastering the technology..."
Cui Heping said a lot in succession.
One issue he emphasized is that the solar panels they use are already the most advanced in the world.
He also made a comparison, "The photoelectric conversion efficiency of the panels on the International Space Station is only 23%, while ours is 31%..."
Wang Hao immediately became confident after hearing this.
He doesn't know much about solar panel technology and is not sure that solar panels made of new upgraded materials will have higher photoelectric conversion efficiency than cutting-edge technology.
Now it's certain.
Wang Hao said with a smile, "We have a research result that has not been made public yet, but we can reveal it to you in advance. We have discovered upgraded silicon elements and detected higher electronic activity."
"To put it simply, solar panels made of upgraded silicon will have a very high photoelectric conversion rate..."
"Exactly how high it is, we still need to experiment."
This news immediately surprised several people, and they finally knew why Wang Hao talked about the issue of solar panels.
If we can create solar panels with a higher photoelectric conversion rate, we can directly increase the auxiliary energy of the lunar module.
Even if the conversion rate is only 1% higher, there is a high probability that the benefits will be greater than correcting the trajectory.
Wang Hao continued, "Solar panels are only one aspect. There are other solutions. You can all consider them."
"For example, materials."
"The Superconducting Materials Research Center developed a special new material last month. This new material has a resistivity higher than silver but lower than copper at room temperature."
"What's more, this material has a transition temperature as high as 201k."
"In addition, this material has a characteristic. The closer it is to the transition temperature, the lower its resistance will be, and the reduction is much greater than that of ordinary metal conductor materials."
"I think you can replace some lines with this new material, which will reduce the energy loss of the circuit..."
Wang Hao listened for a moment and then continued, "Also, we are studying a dense material technology, which can produce materials with higher density and more active electromagnetic properties."
"You can consider using this new type of dense material on some parts."
"Of course, this technology is not perfect yet and we are still researching it, but the moon landing will not be possible this year..."
…
Teacher Zhao, Yuan Zhifang and others walked out of the Mason Mathematics Laboratory Building together.
Their expressions were still a little dazed.
Everyone's expressions were very complicated. After walking together for a long time, Yuan Zhifang sighed, "We seem to be falling behind?"
Others continued to remain silent.
The moon landing program is a big project, a goal that the space agency has been striving for, and hundreds of thousands of scientists are involved.
Since the Apollo lunar landing program, no country has successfully landed on the moon. However, they have built the lunar landing module and most of the other supporting research has been completed.
Preparations are now underway for the moon landing.
Every scholar involved in such a huge project would think that they are at the forefront of science and technology. However, when they came to Xihai University, they found that they seemed to be lagging behind.
Faced with the problem of energy shortage, what they thought of was to correct the trajectory.
There is no way around it.
As a result, the problem was placed in front of Wang Hao, and he proposed several solutions in succession, and each solution involved quite advanced technology.
"When I just listened to Academician Wang talk about the latest research results, I felt like I was about to be eliminated by the times..."
"We don't even know about that."
"I feel the same way. I thought our technology was the most advanced, but it turns out they have so many high-end materials..."
"Hey~~"
Teacher Zhao said, "That's why you feel this way when you come to Academician Wang. Academician Wang has been researching the most advanced technology, and we are just doing engineering."
This sentence is very accurate and true.
Wang Hao is engaged in the research of annihilation physics, and also studies annihilation technology and superconducting technology. He is researching the most cutting-edge technology, while the space agency is using existing technology to realize the project.
This chapter is not over, please click on the next page to continue reading! The nature of the two is different.
Of course, the good news is that Teacher Zhao and his team have made great gains and they know how to solve the problem.
the other side.
After Teacher Zhao and his team left, Wang Hao immediately checked the latest submitted report. There was a lot of data on the research on first-order silicon.
One of the main applications of silicon is in the manufacture of solar panels.
First-order silicon will naturally also conduct experiments on photoelectric conversion rates. In a laboratory environment, first-order silicon has achieved a photoelectric conversion rate of 41%.
Wang Hao was immediately reassured, "The laboratory environment can achieve a conversion rate of 41%, and the solar panels produced can also have a conversion rate of over 35%."
"Trijunction gallium arsenide is indeed a very good material. The theoretical conversion rate can reach up to 50%, but theory is just a theory after all. It is remarkable that it can exceed 30% in practical applications."
"The upper limit of first-order elemental silicon is only about 45%. The upper limit is a little lower, but the application effect is good; the theoretical upper limit of triple-junction gallium arsenide is high, but the actual conversion rate is not high..."
"For the most cutting-edge applications, first-order silicon is more effective."
…
In the following period, material technology at home and abroad developed rapidly.
Materials research and development institutions in various countries seem to have started a competition in the research and development of materials related to first-order iron and first-order lithium.
If you pay attention to academic journals in the field of materials, relevant new materials can appear almost every day, and teams are constantly updating their results.
But the initiative in the competition is in the hands of Annihilation Technology.
Whether it is first-order iron or first-order lithium, only Annihilation Technology Company can buy it.
The research that Wang Hao is concerned about has also made some progress. The biggest breakthrough in the annihilation force field experimental group is to prove the existence of the material's 'radiation critical point'.
They mainly focused on "gold" and found that the "radiation critical point" of pure gold is around 6.7 times. The closer the annihilation force field intensity is to 6.7 times, the lower the radiation intensity of the dense pure gold produced.
At the same time, they have produced dense pure gold with extremely weak radiation.
The radiation is extremely weak, which means it does almost no harm to the human body, so it can be used as a conventional material.
The bad news is that they also determined that the 'future element' first-order iron cannot eliminate its radiation properties.
However, research must be carried out around the ‘future element’ first-order iron.
One characteristic of ‘Future Elements’ is that it does not produce special phenomena, and special phenomena are the biggest obstacle to the creation of annihilation force fields by advanced elements.
"Conventional first-order iron and first-order lithium are affected by special phenomena and cannot be used to create high-intensity DC annihilation force fields, but 'future elements' can."
"So we must continue to conduct research in this direction..."
"We can try to study it with iron isotopes, and we may be able to create future iron elements that do not contain radiation."
The investment in this research is very large, and it is aimed at DC strong annihilation force field technology.
In the future, elements will not be affected by special phenomena and will be able to replace the high-pressure hybrid materials currently used to create high-intensity DC annihilation forces.
The reason why DC strong annihilation force field technology is important is that it can be used to manufacture upgraded materials on a large scale.
No matter how high the intensity of F-rays is, because the coverage area is extremely limited, the materials produced are still too few. The current impact is mainly on radiation issues, and many experiments will have safety risks, but research must be advanced step by step.
on the other hand.
The F-ray experimental team also stabilized the new equipment. They also tried to release fan-shaped F-rays, but unfortunately the experiment still failed.
Wang Hao believes that to release sector-shaped F rays, it is necessary to re-evaluate the internal spiral magnetic field, that is, to create new equipment, and at the same time to increase the energy intensity of the built-in nuclear reactor.
The material testing was fruitful.
High-intensity F-rays have produced several upgraded elements. In addition to silicon, it has been determined that there are also mercury, tungsten, copper and hydrogen.
The discoveries of silicon and copper were both heavyweights.
The first-order silicon content in the magnetized silicon material is very high, and its direct application is to help the space agency manufacture new solar panels.
The discovery of first-order copper was also important.
First-order copper is more active and has much lower resistance than silver, almost close to "zero resistance". It is even considered to be a substitute for superconducting materials.
Unfortunately, the first-order copper content in the magnetized copper material is very low.
In addition, F-ray manufacturing of magnetized materials cannot be mass-produced at all. Every first-order copper produced must be measured in milligrams.
Therefore, if advanced materials want to be developed and applied in large quantities, they still have to rely on DC annihilation force field technology to achieve large-scale manufacturing.
In terms of manufacturing advanced materials, F-rays can only be classified as "laboratory methods" after all.
…
In the blink of an eye, three months have passed.
The science and technology department once again organized a nuclear fusion demonstration project meeting.
This project demonstration meeting is very important, and can even be said to be decisive. Many scholars who are deeply involved in the demonstration project believe that the nuclear fusion project is about to enter the next stage.
This is also the case.
The project demonstration meeting was very unusual at the beginning. Several top decision-makers came to the meeting led by the science and technology department.
The conference also closely follows the focus of domestic and foreign research, and half of the conference is a demonstration of advanced materials technology.
Wang Hao gave a speech at the meeting. He talked about breakthroughs in dense material technology and briefly introduced technologies related to nuclear fusion containers.
Although it was only a brief introduction, the inner antigravity field, outer layer of strong annihilation force field thin layer, coupled with high-end material technology and magnetic field demonstration, made all the scholars at the venue listen with interest.
They all felt that they had seen new technology and were more confident in the nuclear fusion project.
Nothing was decided at the project demonstration meeting, but after the meeting, a series of related meetings were held, including technical meetings in various directions. Most scholars had to attend at least two meetings.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Wang Hao and his colleagues Tang Jianjun, Wang Ye and others participated in multiple meetings in succession, including meetings with high-level decision-makers.
After that, the project is determined to enter the next stage - design.
A super large-scale project will be divided into three stages in total. The first stage is demonstration, and the second stage is design.
Finally, there is manufacturing.
The first two stages involve a lot of experiments, and it is uncertain how long it will take to actually enter manufacturing, which is project approval.
For example, the Manhattan Project.
It took several years from demonstration to design, and then the Manhattan Project was officially established, and it took several years to create the first atomic bomb.
After it is determined that the project has entered the design stage, it also involves experimental allocation, R&D allocation, and the formulation of a promotion plan. Of course, personnel arrangements are also indispensable.
Wang Hao was appointed as the chief designer of the nuclear fusion project.
Tang Jianjun, Wang Ye and Zhou Dongwei from the Institute of Nuclear Physics were appointed as deputy chief designers. There are also more than a dozen academicians and a large number of institutions participating in the cooperation.
Wang Hao served as the chief designer of the project, and his main job was to lead the team to complete the overall design of the nuclear fusion device.
When design involves a certain technology, other scientists and institutions are needed to assist in research.
The nuclear fusion engineering project is very large, and it has attracted much attention after it officially entered the design stage. Many scholars are discussing the time issue of device design.
This question is very straightforward.
For example, the design of high-end fighter jets often spans several years.
Nuclear fusion devices are countless times more complex than high-end fighter jets, and the number of people involved is also very large. How long does it take to design the specific device?
"Normally, this kind of research takes at least five years."
"Academician Wang Hao must be different from others. I guess three or four years will be enough? There are too many technologies involved and too many things to consider."
"Such a complex research can only be done by Academician Wang."
"Three or four years? By then, the design will be completed and the manufacturing stage will begin. It will take at least ten years to complete this project, right?"
"It took Asanguo more than 20 years to build an aircraft carrier. We are fast and efficient, but... ten years?"
"I think it would be amazing if it could be completed in twenty years."
