For industry insiders in the fields of low temperature physics or electromagnetics, electromagnetic guns have never been an unattainable and mysterious product.

In the early 19th century, the Norwegians built the world's first conceptual electromagnetic gun model. During the in full swing of World War II, the Third Reich, the Japanese Military Department, and the US National Laboratory conducted in-depth research on electromagnetic guns, hoping that they could become epoch-making weapons and thus change the course of war.

However, due to the constraints of metallurgy, mathematics and engineering technology at that time, the progress of electromagnetic guns in practicality almost stagnated. Apart from the beautiful hope in theory, they were almost wandering in the darkness of the eternal night in engineering applications, and there was no sign of breakthrough.

After the end of World War II, after realizing that human technology is absolutely unable to solve the stable and huge instantaneous energy supply, miniaturization, heat dissipation and other technical levels, countries around the world almost gave up the development of electromagnetic guns and instead focused on superconducting technology, hoping to obtain breakthroughs from here and solve the difficulties in the practicalization of electromagnetic gun technology.

After all, from the science known to mankind, there is no other way to meet the requirements of electromagnetic guns in miniaturization and instantaneous energy enormous.

Although scientists around the world have invested countless energy and money in superconducting materials, there has been no breakthrough progress from World War II to the mid-1980s, and the scientific community is still wandering around in its original circle. It was not until 1986 that Bernoz and Muller of IBM in Zurich, Switzerland brought a glimmer of hope to the superconducting materials industry.

During the experiment, the two did not look for superconductors with higher transition temperatures from common metal alloy systems, but chose to explore superconductivity from ceramic materials generally believed to have poor conductivity. As a result, they discovered for the first time that superconductivity may exist in the La-Ba-Cu-O system, and its Tc (transition temperature entering the superconducting state) was as high as 35K.

This discovery triggered a global high-temperature superconducting research craze, and then staged an unprecedentedly fierce battle to break the Tc record. Before someone was thrown into this time and space, Zhu Jingwu, the Wu Maokun research group of the University of Houston, and Zhao Zhongxian's research team of the Institute of Physics, Chinese Academy of Sciences, respectively, found that there were Tcs above 90K in the YBa2Cu3O6+ system.

So far, superconducting research successfully broke through the liquid nitrogen temperature zone for the first time (the boiling point of liquid nitrogen is 77K), making large-scale research and application of superconducting possible. Later, in 1988, Sheng Zhengzhi and others discovered a compound with Tc=125K in the Tl-Ba-Ca-Cu-O system, which raised the transition temperature of high-temperature superconducting materials to a new peak.

Before the discovery of high-temperature superconducting materials, nearly all superconductors needed to cool liquid helium to reach the transition temperature. On the earth, the content of helium in the atmosphere is only 5 parts per million on average. The liquid helium used by humans is almost a non-renewable resource and is mainly produced from natural gas. The maximum content of helium in natural gas can reach 7.5%, which is 15,000 times that of air.

However, helium in natural gas is the product of the decay of radioactive elements such as uranium. Only when there is uranium mine near natural gas mines can helium gather in natural gas. This high-helium natural gas mine is not many in the world. Judging from the distribution of global helium-containing natural gas reserves, the United States has more than 50% of the global reserves. It has a decisive monopoly position, while the Republic accounts for only a pitiful 0.2% of the global reserves.

When Zhao Yinong demonstrated the superfluidity and superconductivity of liquid helium to the junior class, the liquid helium used was only 2 liters. Even when the price of liquid helium was relatively low in the 1980s, the cost of these two experiments was still close to US$30. The estimated superconducting coolant required by practical electromagnetic guns was calculated in tons, even if the Americans were rich and wealthy. As a war tool that required more than ten years of service in daily use, it was impossible to afford low-temperature superconducting materials that could maintain superconducting characteristics at liquid helium temperatures.

It can be said that the reason why the United States restarted the development plan for electromagnetic gun weapons in the early 1990s is closely related to the breakthrough progress of high-temperature superconducting materials.

Liang Yuan said that he would participate in the competition by going to a superconducting electromagnetic gun. If experts like Zhao Yinong heard this, he would probably not believe it. In an era when the Internet was not popular, things like electromagnetic guns that were extremely professional were definitely monopolized from a knowledge perspective in narrow circles such as military industry, low temperature physics, and electromagnetic majors. In addition to knowing the basic principles and being shocked by the domineering name of superconducting electromagnetic guns, ordinary people must have no idea about related engineering knowledge.

No one knows that someone comes from the future of the knowledge explosion. Twenty years after the Internet is spreading on this blue planet, as long as you are willing, even the production process of the atomic bomb can be found on the Internet. For Liang Yuan, it is difficult to get a sample of the US military that can pull out to shoot armor. But it is still not difficult to get a sample of an electromagnetic gun that can penetrate coins.

In the extremely chaotic life of Liang Yuan's private life, a woman who regarded Liang Yuan as a blue face was a fan of cosplay. In a large-scale 2D event, Mikoto Misaka, the heroine of "Magic Forbidden Books" who could use electromagnetic gun skills. In order to achieve a shocking effect, Liang Yuan, who was determined to roll the sheets at the time, decided to use his science and engineering knowledge to serve hormones.

Of course, the principle of electromagnetic guns and simple circuit engineering drawings at that time had long been ruined. Liang Yuan had seen a civil science inventor in Zhangjiazhuang Village, Beiwangli Town, Zhao County, North Province, applied for a patent for high-temperature superconducting electromagnetic guns. Thanks to the great Taobao, all the components required for coil electromagnetic guns can be found - thyristors, large-capacity capacitors, copper-core painted wires, voltmeters, boosters, circuit breaker insurance, light emitting diodes... The total cost is less than 5,000 yuan (Note 1).

Liang Yuanhongyan's performance was extremely successful. With the theme song that did not estrange the world, a charming woman dressed in a wide kimono made Mikoto's classic move towards a piece of pre-prepared multi-layer foam. The brilliance of the secondary tube flashed in the wide sleeves of the kimono. The light was slightly fixed. A coin rolled out from the PE tube hidden on the arm, penetrated through the two thin layers of foam, and was deeply embedded in the base material baffle...

On the night of the cosplay event, someone had a wish to taste it. He successfully turned her beauty into a friend of the art of writing poetry. It's a big deal to talk about literature and write poetry. In the era of technology, the girls who can use this old antique method to get started are basically literary dinosaurs. Afterwards, Liang Yuan proudly brags with Cai Xiaobing.

Liang Yuanlian was in a hurry to deal with the various problems of what the two girls' superconducting electromagnetic guns were and when did he learn to assemble that thing.

I worked hard for more than ten minutes, and after receiving a satisfactory reply, the two girls let Liang Yuan go.

Seeing the two girls lying on their thighs again and looking at the leisurely white clouds in the sky, Liang Yuan breathed a sigh of relief. If Jia Jia knew the real reason why he assembled the electromagnetic cannon, would he be thrown into the Hunhe River to feed the great white shark? Liang Yuan thought in great chaoticness.

How could Liang Yuan make a big move to sponsor the Youth Science Competition? The three of them returned to the 909 community and Liang Yuan called Liang Haiping directly.

In the evening, Liang Haiping and Zhang Yi came to the community with two carp.

The two girls and Zhang Yi went to the kitchen to get Liang Yuan's favorite boiled fish. Liang Yuan sat in the living room and told him about the idea he got from the two girls during the day. However, due to the promise to Tang Wan, Liang Yuan did not talk about the tent problem that caused him a headache, but instead threw the cause of the matter on Qingkesai.

"My uncle also knows that the entire Yuanjia founding is closely related to the Qingke Competition. Without the Qingke Competition, there would be no such messy things later. Now we are living a good life. We can't see where we started our business and live a tight life. We should just do it or do it."

"It's that simple?" Liang Haiping asked with a smile.

Liang Yuan also knew that this kind of argument was enough to fool my uncle two years ago, but now Liang Haiping is definitely not going to believe it.

Rubbing his index finger, Liang Yuan smiled and continued, "Old Su and his team had a meeting a few days ago, and my uncle was there. Inspur officially opened for business next month. I drove Liu Feiyang and Wang Xin to Inspur. Inspur always had to make something to relieve their resentment."

"Lao Su and his friends are all cultural people, and they pay a lot of attention. I guess they are allowed to advertise like powerful feed. It is better to make any powerful feed. Pigs eat pigs to increase fatness, and chickens eat chickens to lay eggs. I think invisible advertising methods such as Qingkesai exclusively sponsored by Inspur is more in line with their aesthetics."

After hearing Liang Yuan say this, Liang Haiping felt it was more reliable. He smiled and nodded and said, "Xiaoyuan's statement is almost the same, but how do Xiaoyuan plans to sponsor it?"

"It's better to be the responsibility of the Shangri-La Foundation. I plan to use around one million yuan of funds every year to improve the competition system of the Youth Science Competition, expand the participation subjects, build a group of interest groups closely related to Inspur's main business, and improve the hardware conditions of the Youth Palace in some remote areas..." Liang Yuanyang said several things.

"From the national administrative map, there are almost 1,000 counties in the country. After Inspur is officially established, I asked Liu Feiyang and others to produce a batch of 186-level compatible machines to ensure that each county's Youth Palace or Central School has at least two computers produced by Inspur."

After hearing Liang Yuan say this, Liang Haiping lowered his head and calculated silently, saying, "The value of this batch of computers alone is more than 20 million. Xiaoyuan's advertisement is really a waste of money."
