Tranquility replied: "There are many ways to not use thermal power and hydropower, solar energy and wind energy, which have now entered practical use. There are also tidal power stations, as far as I know, there are already successful real yàn power stations, are you talking about these? ”

"No, no, no, that's not what I'm talking about." Ka'an shook his head, a smug look on his face, "These methods are already considered traditional methods, and my ideas are more advanced than them. ”

"Then it can only be a fight for lightning...... Ning Ning couldn't help laughing, Qin Hai told her a joke, saying that there was a group of residents on a small island who were anti-nuclear power, anti-hydropower, and anti-thermal power, and finally shouted a slogan to fight lightning. Tranquility has always thought that this is just a joke, presumably this benevolent brother in front of him will not have such an idea, right?

Who would have thought that as soon as her words came out, the brother's eyes lit up, and he raised his hand, quite a little like to take Tranquility's hand, and shouted something like "I can be regarded as finding the organization", but fortunately he was still sensible, and knew what the consequences of pulling a strange lady's hand in front of the public. He rubbed his hands in disguise, then asked, "How did you guess?" ”

"I sell cakes!" Tranquility blurted out an English interjection, "Sir, you don't really want to use lightning to solve energy problems, do you?" ”

"Why not?" Without thinking about it, Caan retorted: "There are 60 billion lightning flashes in the world a year, and the energy of a lightning bolt is calculated as 100 kilowatt hours, and the energy of lightning in a year is equivalent to 6 trillion kilowatt hours, which is equivalent to half of the world's annual electricity generation, which can be used by 20 Brazils, so why can't such a large amount of energy be utilized?" ”

"This ......" Tranquility was suddenly dumbfounded by Ka'an, she had the heart to say that the accounts were not calculated like this, but she didn't know where to refute it. Ideas for lightning collection. It is often seen in some middle school student publications in China, but people who are really engaged in scientific research are disdainful of it, and as for the specific reason, Ning Jing really can't think of it for a while.

"Pretty young lady, you can understand when I introduce you." Ka'an saw Tranquility's hesitation. Overjoyed, he eagerly pointed to a bench next to him for customers to rest, and said, "Please sit down, I will show you some materials." ”

"Okay." Tranquility thought that she had nothing to do, and it would be interesting to listen to this citizen scientist talk about it. Judging from the fact that the other party can accurately say the frequency, energy, and global power generation of thunder and lightning, it can be seen that this person is not absolutely "civil", and there is still some common sense.

The two men walked over to the bench and sat down separately. Kaan pulled out a stack of documents from a large leather bag he had with him and stuffed it into Serenity's hand. He said: "Look, this is the blueprint of the lightning collection system I made, of course, this is just a copy of the real Yàn that Franklin made, nothing new. In this system, the most critical are two links, the wire and the energy storage system, and all the current lightning collection systems cannot be put into use because of these two bottlenecks. ”

Tranquility involuntarily took the blueprint handed over by Ka'an. After taking a closer look, I couldn't help but have a new understanding of Ka'an. This drawing is very professionally drawn. There are no various mysteries that ordinary "civil science" likes to make, but a technical schematic diagram that can be understood at a glance. On this diagram, she unexpectedly saw a word that she was very familiar with:

Superconducting!

"You're saying that the wires need to use superconductors?" Tranquility asked, turning her head and looking at Kaan earnestly.

"Yes, you are very professional!" Kaan said happily. "I've checked the relevant information, the voltage of lightning can reach up to hundreds of millions of volts, the current intensity can reach tens of thousands of amperes, and if other wires are used, they will emit high temperatures under strong currents and be burned. As a result, it is impossible to achieve the effect of collecting electrical energy. Therefore, the first key element of the lightning harvesting system is that superconductors must be used as lightning conductors to transmit electrical energy to the energy storage device without loss. ”

"But superconducting materials can only work at low temperatures, which means that you have to keep the superconducting wires in the middle of liquid nitrogen, and the cost of just keeping the wires cold is much higher than the value of the electricity you collect." ”

"Yes, you're right!" As a citizen scientist, Kaan said, he had pitched his ideas to people tens of thousands of times, but he had never met such a serious and professional audience as Serenity, which made him excited. He stretched out his thin finger and pointed to the drawing, and said: "This is the biggest obstacle to the establishment of a lightning collection system, but the existence of this obstacle is entirely because the current superconductivity research has completely gone astray, and according to the current research ideas, superconductivity research will not have a future." ”

One sentence directly gave the tranquility to the thunder and the inside was tender, this benevolent brother really deserves to be a researcher of thunder and lightning, and he speaks with wild thunder. Jing Jing thought to himself that he was also the top authority in the field of superconductivity, how could he allow a citizen scientist to let out such wild words in front of him.

"Mr. Caan, you said that the current superconductivity research has gone astray, can you be clearer?" Tranquility asked.

"Absolutely." "Yttrium-barium-copper-oxygen is the most popular superconducting material at the moment, and almost all superconductologists are revolving around it. However, its structure determines that it is impossible for this material to break through the temperature region of liquid nitrogen, and it is even more impossible to achieve superconductivity at room temperature. In addition, the mechanical properties of yttrium-barium copper oxygen are too poor, and it is difficult to process them into free-form wires......"

"Wait, Mr. Caan, I take the liberty of asking, did you do superconductivity research before?" Tranquility interrupted Ka'an, asking in surprise. Caan's statement just now was very professional, and it was definitely not something that a layman could say casually.

Sure enough, Kaan patted his chest proudly 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-oxygen superconducting materials. It is precisely because of my research on superconducting materials that I turned my interest to lightning collection, and I believe that superconductivity is the key link to solve the problem of lightning collection, but all scholars are going in the wrong direction. ”

"So, what do you think is the right direction?" Tranquility suppressed the shock in her heart and asked Ka'an.

"Iron-based materials!" "I think we should abandon copper-based materials and look for iron-based superconductors, and dope other elements with iron to get superconductors with higher temperatures and better mechanical properties." ”

Serenity looked seriously into Ka'an's eyes, and she was a little suspicious that Ka'an was acting. However, what she saw was a look of persistence and confidence, and if this was a fake, it could only be said that Ka'an's acting skills were too high. Tranquility was silent for a few seconds, and then said: "It is impossible for magnetic matter to have high-temperature superconductivity, this is an authoritative opinion, and your thinking is wrong. ”

Tranquility is a deception, magnetic matter cannot have high-temperature superconductivity, it was indeed an authoritative view, but with the advent of iron-based superconducting materials, this view has been self-defeating. And it is precisely the tranquility of oneself that overturns this view. She said this in front of Ka'an in order to test how much Ka'an knew about superconductivity research, obviously iron-based superconductivity has been around for a few years, and he still regards this as his great prediction, which is a bit abnormal.

"Miss, what you say about the authoritative point of view is not necessarily the truth." Caan's face flushed, and he posed as if he was going to argue 300 times, he was so paranoid that he didn't even wonder why the young girl in front of him could say such professional words. If he thinks a little more, he should at least ask Tranquility's teacher.

"There is not only one mechanism of superconductivity, and the scattering of electrons on the Fermi surface should also be able to produce superconducting properties, which are the characteristics of traditional metal conductivity. If this superconductivity can be proven, the study of superconducting materials at room temperature will be just around the corner! Caan gushed.

Tranquility's eyes widened, what Ka'an said was precisely the research results of her, Chen Zongze and others. Judging from Caan's account, he is not aware of the dynamics of superconductivity in recent years, and is not even aware of the advent of iron-based superconducting materials. However, in this case, he was able to accurately describe the mechanism of iron-based superconductivity, and it is conceivable that if he was given certain practical conditions, he would be able to independently create iron-based superconductors.

This is a big bull whose level is no less than that of Chen Zongze! Tranquility commented in her heart. Although she herself was the discoverer of iron-based superconductivity, she knew that this discovery was largely due to Qin Hai's prompting, and Qin Hai's train of thought came from some kind of inexplicable epiphany. If you want to say that people who can really foresee iron-based superconductivity theoretically, Tranquility has only seen two, one is her mentor Chen Zongze, and the other is the god in front of her.

"Mr. Ca'an, since you have such an idea, why don't you go through Guò Shi Yàn to verify it? If you can prove the existence of iron-based superconducting materials through guò real yàn, wouldn't it be better than standing here and reasoning with me? Tranquility asked suspiciously.

When this sentence was spoken, Ka'an immediately looked like a deflated rubber toy, and the aura of the king eight in his body suddenly disappeared. He hesitated for a while before he said, "Because of the promotion of lightning collection, I was dismissed from my teaching position by them, and the police department confiscated my property, so ...... Now that's all I can do......"

"Because of the promotion of the idea of lightning gathering, the property was confiscated?" Tranquility was even more surprised, between the two, it is clearly irrelevant, is it okay, could it be that Lao Ka has nothing to do with the police station and picked up a wire to the police station and split the police station?

Seeing Tranquility's puzzled look, Caan sighed and talked about his sad past. (To be continued......)
