After that, he smiled and asked Gu Zongyan: "Are you still listening?"
Gu Zongyan said, "Listen! Please tell me! I'm so anxious!"
After teasing Gu Zongyan, Xia Longju said proudly:
"Let me start with the conclusion. The technology I saw today will greatly change our entire country's plans for the next five years. It will change everything, and it will change the entire world situation."
Gu Zongyan concentrated and asked, "Is it really that exaggerated?"
Xia Longju is not a person who likes to brag, and he has never spoken so exaggeratedly before.
He even makes light of important matters, and downplays some very important things. When you listen to him, you have to learn to hear thunder in silence.
From this perspective, it is really incredible that something could be described by him in this way.
"Have we achieved controlled nuclear fusion? Have we made a breakthrough in photolithography technology? Have we made any new advances in nanotechnology?"
Gu Zongyan asked three questions in a row about the major technological breakthroughs he thought were most likely to occur.
After hearing this, even the uneducated Yi Yangbing knew that this conversation was of extraordinary value.
Yi Yangbing and Cai Zhenyi, who were standing behind him, became nervous and pricked up their ears, afraid that they might have missed something.
Zhang Weiqiang didn't even know whether he should still be standing here. He was worried that if he heard a conversation of this level, he would be silenced.
Only Yi Yangbing's female companion, the 18th-tier actress Big Wave, looked a little bewildered. Her cultural level meant that she didn't quite understand the meaning of those words.
After Gu Zongyan finished speaking, Xia Longju shook his head and said:
"What you mentioned is indeed very important, but I suggest you try to be a little bolder."
"Be bolder..." Gu Zongyan was at a loss.
He thinks these techniques are already very bold, how much bolder can they be?
"Have you found the alien spaceship?" Gu Zongyan asked.
Xia Longju laughed out loud.
"Old classmate, you're quite humorous," Xia Longju said with a smile. "If I really found aliens, would I tell you about it here?"
Xia Longju was honest. He didn't say whether he found it or not, but just said he couldn't tell. Gu Zongyan also laughed.
Xia Longju restrained his expression and continued, "Do you know about room-temperature superconductivity?"
"Room temperature superconductivity?"
Except for Zhang Weiqiang, who had a background in science and engineering, no one present had ever been exposed to this field, and had never even heard of its name.
Only Gu Yuqing frowned, feeling as if she had heard this word somewhere before.
Where is it?
Zhang Weiqiang said tremblingly, "I know a little."
Xia Longju glanced at him and said kindly, "You go ahead."
Zhang Weiqiang was like when he was a kid and his teacher called his name in class. He said nervously:
"Superconductivity is a phenomenon in which the electrical resistance of a conductor disappears at extremely low temperatures, right? I've only come across it before, but I don't understand it very well."
"What you said is very professional." Xia Longju nodded.
Gu Zongyan was a little confused.
The reason he was able to build such a big business is that his intelligence gave him a great advantage and he is not a person who knows nothing.
But based on Zhang Weiqiang's definition, he couldn't tell how it was high enough to challenge controlled nuclear fusion, nanotechnology, photolithography machines and other technologies.
Xia Longju said, "At first, I didn't understand the significance of this thing. Isn't it just a lack of resistance? But then I learned something that made me realize how amazing this technology is."
"Do you know how much power loss there is in transmission lines?" Xia Longju asked. "This year, our national power generation is 7.5 trillion kilowatt-hours. Do you know how much loss there is just in the power lines supplying businesses?"
"How much?" Gu Zongyan asked.
"370 billion kilowatt-hours!" Xia Longju said, "This only accounts for the loss of electricity used by businesses. Most businesses use electricity in high-voltage areas, so the loss rate is not high. The loss rate of residential electricity is even higher!"
"A 10-kilovolt high-voltage transmission line loses an average of 1.5 kilowatt-hours of electricity per kilometer. This is all due to power loss caused by resistance," said Xia Longju.
"my country is a country with uneven development and uneven resource distribution. The north has more coal, the south has more water conservancy. At the same time, economic development is also uneven. The eastern coastal areas account for 60% of the country's electricity consumption, but most of the energy they need depends on transportation."
After a pause, Xia Longju continued, "Just think about it. How much electricity is lost in the process of transporting it from the west to the east?"
Cai Zhenyi nodded and said, "Oh, so if the resistance disappears, then there's no need to waste that much electricity, right?"
"right."
After Xia Longju finished speaking, he took a sip of water and continued, "But this is only the most insignificant use of this technology."
"Um?"
Xia Longju continued, "Resistance is reduced to zero, which means all electrical appliances will no longer heat up. This also means that long-distance power transmission no longer requires alternating current (AC), but can directly use direct current, eliminating the need for conversion."
Then, lowering his voice, he said, "This also means that quantum computers can be realized in superconductors. It also means that the key constraints on controlled nuclear fusion have disappeared."
"Controlled nuclear fusion? Why are we still talking about controlled nuclear fusion?" Gu Zongyan said.
Xia Longju enjoyed the confused look of his old classmate and said slowly:
"The current technical difficulty of controlled nuclear fusion is the low conversion rate. The energy required to start a thermonuclear power plant is higher than the output. However, with superconductors, the starting energy of thermonuclear fusion can be reduced to less than 10% of the current level. This solves a major difficulty in the commercialization of controlled nuclear fusion."
