Chapter 668 Fighting Lightning

Jing Jing replied: "Instead of thermal power, there are many hydropower methods. Solar power and wind power have now been put into practical use. There are also tidal power stations. As far as I know, there are already successful experimental power stations. These are what you are talking about.

?"

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

"Then we can only fight lightning..." Ning Jing couldn't help but laugh. Qin Hai told her a joke, saying that a group of residents on a small island were anti-nuclear power, anti-hydropower, and anti-thermal power. Finally, he shouted:

A slogan that spells lightning. Tranquility has always thought it was just a joke. Presumably the friend in front of me wouldn't have such an idea, right?

Unexpectedly, as soon as she spoke her words, the man's eyes shone with light. He raised his hand, wanting to hold Jing Jing's hand and shout something like "I have found an organization." Fortunately, he still

He was sensible and knew the consequences of holding the hand of a strange lady in public. He rubbed his hands in a covert manner, and then asked: "How did you guess that?"

"I sell cakes!" Ning Jing blurted out with an English exclamation, "Sir, you don't really want to use lightning to solve the energy problem, do you?"

"Why not?" Ka'an retorted without thinking: "There are 60 billion lightning strikes in the world every year. The energy of one lightning bolt is calculated as 100 kilowatt hours. The energy of lightning in one year is equivalent to 6 trillion kilowatt hours.

It is equivalent to half of the world’s annual power generation and can be used by 20 Brazils. Why can’t such a large amount of energy be used?”

"This..." Jing Jing was dumbfounded by Ka'an. She wanted to say that this was not how the accounts were calculated, but she didn't know how to refute it. Ideas about lightning collection were often published in some domestic middle school student publications.

I see, but people who are really engaged in scientific research are dismissive of this. As for the specific reasons, I really can't remember it for a while.

"Beautiful lady, you will understand after I introduce it to you." Ka'an was elated when he saw Jing Jing's hesitant look, and eagerly pointed to a bench next to him for customers to rest. He said: "Please sit down,

I will show you some materials."

"Okay." Ning Jing thought that he had nothing to do. It would be interesting to listen to this citizen scientist. From the fact that the other party could accurately tell the frequency, energy and global power generation of thunder and lightning, it can be seen that this person is quite capable.

It's not an absolute "civil science", but it still has some common sense.

The two walked to the bench and sat down separately. Ka'an took out a stack of information from a large leather bag he carried with him, stuffed it into Jing Jing's hand, and said, "Look, this is the thunder and lightning I drew.

Collection system drawings, of course, are just a replica of Franklin's experiment, nothing new. There are two links in this system, wires and energy storage systems. All current lightning collection systems are because of these two

bottleneck and cannot be put into application.”

Ning Jing couldn't help but took the drawing handed over by Ka'an. After taking a closer look, she couldn't help but have a new understanding of Ka'an. This drawing was very professional and not something that ordinary "civilians" like to do.

All kinds of mysteries, but a technical diagram that can be understood at a glance. On this diagram, she unexpectedly saw a vocabulary that she was very familiar with:

Superconducting!

"You mean, the wires need to use superconductors?" Jing Jing turned her head and looked at Ka'an seriously and asked.

"Yes, you are very professional!" Ka'an said happily, "I have checked the relevant information. The voltage of lightning can reach up to several hundred million volts. The current intensity can reach tens of thousands of amps. If other wires are used, the high current will

It emits high temperatures and is burned down, making it impossible to collect electrical energy. Therefore, the first key factor in the lightning collection system is to use superconductors as lightning conductors to transmit electrical energy to the energy storage device without loss."

Jing Jing said: "But superconducting materials can only work at low temperatures, which means you have to keep the superconducting wires in the middle of liquid nitrogen. The cost of just maintaining the low temperature of the wires is much higher than the electricity you collect.

It’s valuable.”

"Yes, you are right!" Ka'an said. As a civilian scientist, he has sold his ideas to people more than tens of thousands of times, but he has never met an audience as serious and professional as Jingjing. This makes him

He suddenly became excited. He pointed at the drawing with his skinny fingers and said: "This is the biggest obstacle to establishing a lightning collection system, but this obstacle exists entirely because the current research on superconductivity has completely gone astray.

If we continue with the current research ideas, there will be no future for superconducting research."

With just one sentence, Ning Jing was shocked on the outside and tender on the inside. This dear man really deserves to be a researcher of thunder and lightning, and he spoke with a thunderous tone. Ning Jing thought to himself that he was the top authority in the field of superconductivity, how could he tolerate this person?

Civilian scientists make such wild claims in front of themselves.

"Mr. Ka'an, you said that the current research on superconductivity has gone astray. Can you be more clear?" Jing Jing asked.

"Of course." Ka'an said confidently, "Yttrium barium copper oxide is currently the most popular superconducting material, and almost all superconducting scientists are focusing on this material. However, its structure determines this

It is impossible for the material to break through the liquid nitrogen temperature range, and it is even more impossible to achieve normal temperature superconductivity. In addition, the mechanical properties of yttrium barium copper oxide are too poor, making it difficult to process into free-shaped wires..."

"Wait a minute, Mr. Ka'an, let me take the liberty to ask, have you ever done any research on superconductivity?" Ning Jing interrupted Ka'an and asked in surprise. Ka'an's statement just now was very professional.

It's not something a layman can say casually.

Sure enough, Ka'an proudly patted his chest and said: "I have been engaged in research on conductive materials for nearly 30 years, and I have also been involved in yttrium barium copper oxide superconducting materials. It was precisely because of my research on superconducting materials that I turned my interest to

Regarding lightning collection, I believe that superconductivity is the key to solving the problem of lightning collection, but all scholars’ research has gone in the wrong direction.”

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

"Iron-based materials!" Ka'an said decisively, "I think we should abandon copper-based materials and look for iron-based superconducting materials. By doping other elements into iron elements, we can obtain superconductors with higher temperatures and better mechanical properties.

."

Jing Jing looked at Ka An's eyes seriously. She was a little suspicious that Ka An was acting. However, what she saw was a look of persistence and confidence. If this was fake, it can only be said that Ka An's acting skills were really good.

Too high. Jingjing was silent for a few seconds, and then said: "It is impossible for magnetic materials to have high-temperature superconductivity. This is an authoritative view. Your thinking is wrong."

Jing Jing's words are deception. It was indeed an authoritative view that magnetic materials cannot have high-temperature superconductivity. However, with the advent of iron-based superconducting materials, this view has been overturned.

It was Jing Jing himself who held this view. The reason why she said this in front of Ka'an was to test how much Ka'an knew about superconducting research. Obviously, iron-based superconductors have been around for several years, but he still regarded this as his own.

The great foresight, this is a bit abnormal.

"Miss, the authoritative point of view you mentioned is not necessarily the truth." Ka'an blushed and pretended to argue for 300 years. He was so paranoid that he didn't even think about why.

The young girl in front of him could speak such professional words. If he thought more, he should at least ask Jing Jing's mentor.

"There is not only one mechanism of superconductivity. Through the scattering of electrons on the Fermi surface, superconducting properties should also be produced. This property is exactly the conductive property of traditional metals. If the existence of this kind of superconductivity can be proven

, Research on room-temperature superconducting materials will be just around the corner!" Kaan said gushingly.

Jing Jing's eyes widened. What Ka'an said was exactly the research results of her, Chen Zongze and others. Judging from Ka'an's narrative, he did not understand the dynamics of the superconducting community in recent years, and even

He didn't even know that iron-based superconducting materials had been introduced. However, in this case, he was able to accurately describe the mechanism of iron-based superconducting. It is conceivable that if he was given certain experimental conditions, he could completely independently

Create iron-based superconductors.

This is a master whose level is no less than that of Chen Zongze! Ning Jing commented in her heart. Although she herself was the discoverer of iron-based superconductivity, she knew that this discovery largely benefited from Qin Hai’s work.

Tip, and Qin Hai’s idea came from some inexplicable epiphany. Speaking of people who can truly predict iron-based superconductivity theoretically, Ning Jing has only met two people. One is her mentor Chen Zongze, and the other is

The godly Ka'an in front of me.

"Mr. Ka'an, since you have such an idea, why don't you verify it through experiments? If you can prove the existence of iron-based superconducting materials through experiments, wouldn't it be stronger than standing here and reasoning with me?" Ning Jing

asked suspiciously.

After saying these words, Ka'an immediately felt like a deflated rubber toy, and all the bastard energy in his body was gone. He hesitated for a while, and then said calmly: "Because of the promotion of thunder and lightning collection

I was dismissed from my teaching position, and the police station also confiscated my property, so... now I can only do this..."

"Because of promoting the idea of ​​lightning network, your property was confiscated?" Ning Jing was even more surprised. There is obviously no connection between the two. Could it be that Lao Ka connected a wire to the police station for nothing and hacked the police station?

Already?

Seeing Jing Jing's confused look, Ka'an sighed and talked about his sad past. (To be continued.)
