Vol 2 Chapter 668: Fight lightning

Tranquil replied: "There are many ways to use no thermal power or hydropower. Solar energy and wind power are now practical. There are also tidal power stations. As far as I know, there are already successful experimental power stations. What you are saying are these ?"
"No, no, that's not what I'm talking about." Kaan shook his head, his face showing pride. "These methods are already traditional methods, and my ideas are more advanced than them."
"It can only be fighting lightning ..." Tranquil could not help laughing, Qin Hai told her a joke, saying that a group of residents on a small island had anti-nuclear power, anti-hydro power, anti-fire power, and finally shouted A slogan of lightning. Tranquility has always thought that this is just a joke. Presumably this man doesn't have such a thought right now?
Unexpectedly, as soon as her words came out, the dear's eyes glowed. He raised his hand, and quite a few wanted to take a quiet hand, shouting something like "I can count as an organization." Fortunately, he still It is reasonable to know the consequences of pulling a strange lady's hand in the public. He rubbed his hands concealed and asked, "How did you guess?"
"I sell cakes!" Serenity blurted out an English exclamation, "Sir, don't you really want to use lightning to solve energy problems?"
"Why not?" Kaan retorted without thinking: "There are 60 billion lightning bolts a year in the world. The energy of a lightning bolt is calculated at 100 kWh. The energy of a lightning bolt is equivalent to 6 trillion kWh a year. It is equivalent to half of the world ’s annual power generation and can be used by 20 Brazil. Why ca n’t such a large amount of energy be used?

"This ..." Tranquility was dumbed by Caan at once, and she deliberately said that the account was not calculated like this, but she did not know how to refute it. Ideas about lightning collection. It is also often seen in some domestic high school student publications, but those who are really engaged in scientific research are dismissive of it. As for the specific reason, I couldn't remember the moment of tranquility.
"Pretty lady. You will understand after I introduce you." Ka An saw the serenity and hesitation, anxiously pointing to a nearby bench for customers to rest and said, "Please sit down, I will show you some materials. "
"Okay." Serenity thinks that he had nothing to do, and it would be interesting to listen to this folk scientist. From the fact that the other party can accurately tell the data of the frequency, energy and global power generation of lightning, it can be seen that this person is not an absolute "civilian", and still has some common sense.
Two people walked to the bench. Sit down. Kaan took out a stack of information from a large leather bag that he took with him, shoved it into quiet hands, and said, "Look, this is the drawing of the lightning collection system I drew. Of course, this is just what Franklin did. There is nothing new about a copy of the experiments that have been performed. In this system, the most critical are the two links, the wires and the energy storage system. All current lightning collection systems cannot be put into use because of these two bottlenecks. "
Tranquility involuntarily accepted the drawings handed over by Kaan. Taking a closer look, I couldn't help but have a new understanding of Kaan. This drawing is very professional, and there are no mysterious things that ordinary "civilians" like to make. It is a technical diagram that can be seen at a glance. On this schematic, she unexpectedly saw a vocabulary she was very familiar with:
Superconducting!
"You mean, wires need superconductors?" Tranquility turned his head and looked at Caan intently.
"Yes, you are very professional!" Kaan said cheerfully, "I have checked the relevant information. The voltage of lightning can reach several hundred million volts and the current intensity can reach tens of thousands of amps. If other wires are used, it will be in strong current It is high temperature and burned down, so it can not achieve the function of collecting electrical energy. Therefore, the first key factor of a lightning collection system is that superconductors must be used as the lightning conductor to transfer the electrical energy to the energy storage device without damage. "
Serenity said: "But superconducting materials can only work at low temperatures. This means that you must keep the superconducting wire in the middle of liquid nitrogen. The cost of maintaining the temperature of the wire is much higher than the electrical energy you collect. Worth it. "
"Yes, you're right!" Kaan said, as a folk scientist, he sold his thoughts to people more than 10,000 times, but never encountered a serious and professional audience like tranquility, which made He was suddenly excited. He reached out his thin finger and pointed at the drawing, saying, "This is the biggest obstacle to the establishment of a lightning collection system, but the existence of this obstacle is entirely because the current superconducting research has gone completely astray. Going forward, superconducting research is not promising. "
In one sentence, he gave Lei Dewai Jiao Linen the tranquility directly. This man is really worthy of studying thunder and lightning, and he speaks with mad thunder. Quiet self-confidence can also be regarded as the top authority in the field of superconductivity. How can a folk scientist be able to release such crazy words in front of himself?
"Mr. Kaan, you said that the current research on superconductivity has gone astray. Can you say more clearly?" Quiet asked.
"Of course you can," Caan said confidently. "Yttrium barium copper oxide is currently the most popular superconducting material, and almost all superconducting scientists are spinning around this material. However, its structure determines this kind of It is impossible for the material to break through the liquid nitrogen temperature region, and it is even more impossible to achieve normal temperature superconductivity. In addition, the mechanical properties of yttrium-barium-copper-oxygen are too poor to be processed into free-form wires ... "
"Wait, Mr. Ka'an, I ventured to ask, have you ever done research on superconductivity?" Tranquility interrupted Ka'an and asked in amazement. The statement made by Kaan just now is very professional, which is definitely not something a layman can say casually.
Sure enough, Ka'an proudly patted his chest and said, "I have been engaged in the research of conductive materials for nearly 30 years, and I have also been involved in yttrium-barium-copper-oxide superconducting materials. It was also because of my research on superconducting materials that I turned my interest Lightning collection, I think that superconductivity is the key link to solve the problem of lightning collection, but the research of all scholars has gone in the wrong direction. "
"So, what do you think is the right direction?" Tranquility asked Kaan with the shock in her heart.
"Iron-based materials!" Caan said categorically. "I think we should abandon copper-based materials and look for iron-based superconducting materials. By doping other elements in iron, we can obtain higher temperature and better mechanical properties of superconductors. . "
Quietly looking at Kaan's eyes, she wondered if Kaan was acting. However, what she saw was a look of perseverance and self-confidence. If this was false, it could only be said that Kaan's acting skills were too high. Tranquility remained silent for a few seconds, and then said, "It is impossible for magnetic substances to have high temperature superconductivity. This is an authoritative point of view. Your thinking is wrong."
The word serenity is a scam. Magnetic materials cannot have high-temperature superconductivity. It was indeed an authoritative point of view, but with the advent of iron-based superconducting materials, this point of view has been self-defeating. To overthrow this view is precisely to calm yourself. She said this in front of Kaan, in order to test how much Kaan knows about superconducting research. Obviously iron-based superconducting has been around for a few years. He also regards this as his great foresight, which is a bit abnormal. .
"Miss, the authoritative point you speak is not necessarily the truth." Kaan blushed and put on a frame that was intended to argue about 300. He was so paranoid that he didn't even think about why. Right now the young girl was able to say such professional words. If he thinks more, at least he should ask the quiet teacher.
"There is more than one kind of superconducting mechanism. Through the scattering of electrons on the Fermi surface, it should also be able to produce superconducting characteristics, which are exactly the characteristics of traditional metal conduction. If it can prove the existence of such superconductivity , Research on superconducting materials at room temperature is just around the corner! "Kaan torrented.
Quiet eyes were widened. What Kaan said was precisely the research results of her and Chen Zongze and others. From the perspective of Kaan's narrative, he did not understand the dynamics of the superconducting academic community in recent years, and even knew that iron-based superconducting materials have been available. However, in this case, he was able to accurately describe the mechanism of iron-based superconductivity. It is conceivable that if given certain experimental conditions, he would be able to manufacture iron-based superconductors independently.
This is a Daniel who is no less than Chen Zongze! Serenity commented in her heart ~ EbookFREE.me ~ Although she herself is the discoverer of iron-based superconductors, she knows that this discovery largely benefited from Qin Hai's hints, and Qin Hai's ideas came from In some sort of inexplicable epiphany. To say that people who can theoretically foresee the iron-based superconductor have only seen two quietly, one is her mentor Chen Zongze, and the other is Kaan, the in front of her.
"Mr. Ka'an, since you have such an idea, why not verify it through experiments? If you can prove the existence of iron-based superconducting materials through experiments, wouldn't it be more reasonable to stand here and tell me?" Tranquility Asked suspiciously.
Saying this sentence, Ka An Lima was like a deflated rubber toy, and the whole body of Wang Baqi's air suddenly disappeared. He waited for a while before he said negligently: "I was dismissed from the teaching post because of the promotion of the collection of thunder and lightning, and my property was confiscated by the police station, so ... now I can only do this ..."
"Because of the promotion of the idea of ​​lightning collection, the property was confiscated?" Tranquility was even more surprised. The two were clearly irrelevant, okay. Could it be that the old card was fine for the police station, and the police station was split? Is it?
Seeing calmness, Kaan sighed and talked about her sad past. (To be continued)
