Chapter 2009: superconductor

Qin Guan is also very speechless. Qin Guan is definitely not a qualified matchmaker, and he is not good at paying attention to other people's families. Now, Major Yang said generously: "Okay."
However, there is no more to follow, and the scholar on the side winks one after another, so Yutong can only stop the topic.
Looking at Major Yang, there seemed to be no difference, but seeing his mental point suddenly rise, he knew that his mood must have been abnormally fluctuating, and he must have remembered something.
Qin Guan couldn't ask anymore.
"Come on, let's watch TV." It was the scholar who broke the embarrassment and turned on the TV. Needless to say, the whole land outside has become a world wrapped in silver, which is most comfortable for the north. It’s just staying at home, drinking small wine, boiling lamb and watching TV. Now, many families don’t have a TV. In Qin Guan, it’s already a large-screen LCD TV. From the dining table, you can’t see To the screen but can hear clear sound.
Listening to that familiar tune, you know that it is news broadcast. Moreover, domestic news has passed, and there are five minutes left to broadcast international news.
"Now, we broadcast the latest news. The Chinese scientist Zhu of Eagle Country announced that they have obtained superconductors above 90K for the first time. This is very important for the research of superconductors."
Hearing this, Qin Guan's hand stopped immediately, and his chopsticks seemed to be shaking.
"Huh, if I want to say it, don’t emphasize the Han Chinese. They are originally Han Chinese, but they don’t want their own country, but they went to a foreign country and joined the foreign nationality. Compared with our older generation Deng Jiaxian and Qian Xuesen, What are these people?" Xiucai's words contained dissatisfaction.
It is normal for people to go to high places, but they don’t even want their own motherland. Such people are despised by scholars. Here is their roots. Without the motherland, where is there a person?
"Hmph, these people, they will definitely say that they are doing research, because the domestic level is low, and their value cannot be realized. They are looking for a better platform. They only have scientific research in their eyes, without borders." Xiucai continued, raising his head and drank a glass of wine into his stomach, obviously starting to sulking.
Seeing Xiucai's appearance, Xiao Lu gently stroked his hand with his hand, and his hand gently put down the wine glass. He always listened to Xiao Lu's words.
"Superconductors are the country's most important weapon." Qin Guan said: "In this regard, we absolutely cannot relax."
In the past, Qin Guan did not have this ability, but now it is different. Qin Guan already has this new system and found many things that can be easily obtained, such as this superconductor.
Ordinary conductors have resistance. Because of the resistance, when the current passes through, it will generate heat and consume electrical energy. This is also a conflict of interests between the power plant and the user. I sent out five thousand kilowatt-hours of electricity. To charge five thousand kilowatt-hours of electricity, but the user refused. If the user only received four thousand kilowatt-hours, he was given four thousand kilowatt-hours. The remaining one thousand kilowatt-hours was all consumed on the transmission line.
Of course, the actual gap is not so big, which is also the reason for using high-voltage transmission, but there must be losses. But superconductors are different. The resistance of superconductors is zero.
What are the benefits?
The first is to save the energy loss of power transmission. If superconductors are used for transmission lines and power stations to users, there will be no loss.
However, this is just a dream. No transmission line uses this material because it is too expensive.
The biggest difficulty of superconductors is temperature. When superconductors were first discovered, the mercury coil was lowered to near absolute zero, and the resistance suddenly disappeared.
And to reduce the temperature to absolute zero, the effort is very great, at least with current technology, it is absolutely high.
Therefore, there have been countless scientists devoted to the research of high-temperature superconductors. Although they are called high-temperature superconductors, they are still more than one hundred degrees below zero. Among the commonly used low-temperature objects, liquid nitrogen is minus 196 degrees. If the critical temperature of superconductors is changed from Objects between absolute 0 degrees and minus 196 degrees are low-temperature superconductors. Those higher than minus 196 degrees are high-temperature superconductors. If they can achieve superconductivity at daily temperatures, they are normal temperature superconductors.
Now, everyone is increasing this critical temperature little by little. This 90K temperature has reached the temperature range of liquid nitrogen, which means it is easier to use. This is definitely a major discovery.
"Superconductors, for us, the most useful thing is electromagnetic ejection, including electromagnetic guns. The most important part of it is the superconducting coil." Qin Guan said: "We must carry out basic physics research in this field. "
At this time, the two children were already full. Yutong took the two children to the children's room to play. At the same time, he knew that their adults were talking about some very secret things, which were not easy for them to know.
When Qin Guan was on the table, he was already talking.
"In the future, our aircraft carriers will inevitably use electromagnetic catapults. Our short-range protection weapons will inevitably be replaced by electromagnetic guns, or even capital naval guns. They may be replaced with electromagnetic guns. Therefore, we must pay attention to it. The development of this system." Qin Guan said.
Speaking of weapons, Major Yang is an absolute expert. Now, hearing Qin Guan say this, he can immediately sketch a scene in his mind.
At present, the most mature catapult is the steam catapult. If it is said that there is an electromagnetic catapult, it will definitely make people think that it is a fantasy. However, Qin Guan knows that this is not science fiction. Just in 2020, Yingguoren’s Aircraft carriers, Han's own aircraft carriers, have all begun to use electromagnetic ejection, and Han's electromagnetic ejection is even more advanced!
There are many advantages of electromagnetic ejection. The whole process has suitable acceleration. At the same time, it is also convenient for light-load ejection of drones, etc. Now, we will start to make technical reserves and achieve breakthroughs in the field of high-temperature superconductors!
Moreover, in that parallel time and space, the research on high-temperature superconductivity in Han was originally from an advanced position.
Now, Qin Guan is looking forward to it.
As long as the country is determined, it can use its own system to exchange advanced superconductor research results. Huh, do you think you can easily produce research results if you go abroad? The country with real potential is Han!
"Yes, in this respect, we really should put a lot of effort into research." Major Yang said, "I will report tomorrow. You have to be prepared."
What Major Yang said, Qin Guan certainly knew what it meant. He patted his chest: "Don't worry, I'm already ready."
