The Science Fiction World of Xueba

A week later, Pang Xuelin appeared in New York again on a special plane.

Pang Xuelin first went to the United Nations Building to meet the new Secretary-General of the United Nations, Dewey Clive, and the rotating chairman of the PDC, Preet Leslie. Afterwards, Pang Xuelin went directly to the Strategic News Bureau of the Planetary Defense Council, which is not far from the United Nations headquarters.

"Director Vader, it's a pleasure to see you again!"

"Professor Pang, what can I do for you?"

Wade was obviously a little surprised by Pang Xuelin's arrival, and went straight to the point.

It's been five years since Vader didn't seem to have changed much. He was smoking a cigar, and the smoke shrouded his stern face, but his sharpness remained the same.

Pang Xuelin gave Cheng Xin a wink, and Cheng Xin led his followers out of Wade's office, not forgetting to close the door before going out.

Pang Xuelin stepped forward, casually pulled the swivel chair in front of the desk, sat down opposite Vader, and said with a smile, "Mr. Vader, five years ago, I asked you if you would like to work in the Wallfacer's office. You choose Now, I would like to ask, are you willing to work in the Galapagos Islands? As long as you are willing, you will be the chief executive officer of Halo City, Halo City and Halo Institute for Advanced Study in the next 20 years All the construction and development of will be led by you."

Vader took a deep breath of the cigar, the smoke was lingering, covering the subtle changes on his face.

"why me?"

Vader said coldly.

A member of the Office of the Wallfacer, and the chief administrative officer of Star Ring City, the power here is completely different.

Today's Star Ring City is a well-known existence both in the academic world and internationally.

The only port city designated by the Wallfacers has invested a lot in the field of basic science. There are even rumors that Xinghuan City is preparing to develop controllable nuclear fusion technology.

Among other things, the annual PDC funds of up to 50 billion U.S. dollars in Star Huancheng alone are enough to make anyone salivate.

Therefore, Vader seemed a little surprised that Pang Xuelin suddenly proposed that he be the Chief Executive Officer of Star Ring City.

Pang Xuelin laughed and said: "I am very optimistic about you. In fact, I have been optimistic about you five years ago. The overall planning ability and firm belief you showed during the implementation of the ladder plan are all what I need.

Also, I see ambition in your eyes. I need people like you to protect Xinghuan City, and the future of mankind also needs people like you. I believe you can bring glory to Xinghuan City. And I heard from Vadim that you seem to be getting tired of being the director of PIA, and want to go to the future through hibernation! I hope you will work for me for twenty years before hibernating! "

"Then what can you give me?"

The expression on Vader's face remained unchanged.

Pang Xuelin said: "Absolute power! But there is a premise, I want you to complete all the technical accumulation of controllable nuclear fusion, modern agricultural factories, and electromagnetic orbital space launch systems within 20 years!"

Wade frowned and said, "Professor Pang, your request is a bit high. The annual investment of 50 billion US dollars may not be enough."

Pang Xuelin smiled lightly: "How much profit do you think an ultra-high-density energy storage battery can bring to Xinghuan City every year?"

"Ultra-high density energy storage battery?"

Vader had a look of surprise on his face.

Pang Xuelin nodded.

The ultra-high-density energy storage battery is naturally the kind of super battery brought from the world of Wandering Earth.

Although in a short period of time, it cannot make human energy technology develop by leaps and bounds, but it can profoundly change the global energy structure.

The Three-Body World has been able to industrially produce high-purity graphene materials in large quantities. It is not too difficult to manufacture super energy storage batteries in the wandering earth.

In fact, in the three-body world, there is also the concept of graphene batteries.

But this is not an accurate concept. To be precise, a little graphene is basically added to the material to improve part of the energy of the lithium battery. It can be called a graphene-based lithium-ion battery.

In the laboratory, scientists have been able to increase the specific energy of graphene-based lithium-ion batteries to more than 600wh/kg, twice that of the best lithium-ion batteries currently on the market.

Moreover, this kind of battery only takes less than 8 minutes for a single full charge, and its service life is four times that of traditional hydrogenated batteries, twice that of lithium batteries, and its weight is only half that of traditional batteries. In the field of energy storage batteries, this can be regarded as a revolution. breakthrough.

But this is only the data in the laboratory. In the practical stage, it is basically misfired.

The reason is simple. First of all, the cost of all-graphene batteries is very high, and the preparation is difficult, making mass production almost impossible. Some of the amazing data released now basically come from graphene batteries with extremely high purity, which only appear in the concept stage or in the laboratory.

Secondly, the role of "doped graphene battery" in lithium batteries is a conductive agent or electrode lithium intercalation material, but compared with the low cost of traditional conductive carbon and graphite, the energy improvement brought by the former is not enough to attract manufacturers.

Third, the high specific surface area of ​​graphene materials is not compatible with the current technical system of the lithium-ion battery industry.

In addition, problems such as the impact of other materials and the high difficulty of the dispersion process restrict the application of graphene in lithium batteries.

And theoretically speaking, the theoretical capacity of pure graphene negative electrode material is only 0.78KWh/kg, which is only much better than the lithium batteries on the market, but compared with the theoretical capacity of the legendary lithium-air battery of 10kwh/kg, The two are not at the same level at all.

What Pang Xuelin wants to do is the official lithium-air battery. In the world of wandering earth, it has a more accurate name, graphene-based lithium-air battery.

Li-air batteries are not a new concept.

Since the oxygen in the air is used as the active material on the positive electrode, the capacity density of the positive electrode is theoretically unlimited, and the capacity can be increased.

In addition, if lithium metal is used as the negative electrode, the theoretical capacity will increase by one digit compared with lithium-ion rechargeable batteries.

However, lithium-air batteries also have a fatal flaw, that is, lithium hydroxide, a solid reaction product, will accumulate on the positive electrode, blocking the contact between the electrolyte and the air, resulting in a discharge stop.

In the world of Wandering Earth, scientists have developed a graphene two-dimensional film with a large specific surface area, which allows lithium hydroxide generated by solid reactions to accumulate on the film, thus solving this long-standing problem in the battery industry.

This technology is quite mature in the world of Wandering Earth. In the world of Trisolaris, a breakthrough has been made in the industrial production of high-purity graphene. As long as we continue to invest in research and development in this direction, Pang Xuelin expects to be able to produce such a battery within three years.

Wade had some doubts about the so-called ultra-high-density energy storage battery. After pondering for a moment, he raised his head and said, "Professor Pang, I hope to visit Xinghuan City. As for whether I agree to your request, it depends on my acceptance." Come down and see the results in Star Ring City."

Pang Xuelin laughed and said, "You are always welcome!"

...

Going downstairs from the PIA headquarters, Pang Xuelin saw Cheng Xin chatting with Vadim.

Seeing this simple and honest aerospace engineer, Pang Xuelin felt a little emotional.

According to the original script, Vadim had already been killed by Vader at this time, but now, he is still alive and well, and it can be seen that his life is not bad.

"Cheng Xin, it's about time we left!"

"Oh, okay, brother Vadim, then I'll go first, and I will contact you when I have time!"

Pang Xuelin and Cheng Xin got into the car, and Cheng Xin said, "Professor Pang, what did Director Wade say?"

Pang Xuelin said with a smile: "He said that he would go to Xinghuan City with me. If Xinghuan City meets his requirements, he will agree."

Cheng Xin nodded and didn't ask any more questions.

The convoy returned to the Hilton Hotel. As soon as they arrived at the entrance of the hotel, Pang Xuelin found that the security of the hotel seemed to be much tighter than before.

When he got out of the car, he saw a UN official hurried up to greet him, and said, "Professor Pang, I am Bryant, the liaison officer of Wallfacer Rey Diaz, and Rey Diaz wants to see you!"

Pang Xuelin couldn't help being taken aback.

He didn't have much contact with Rey Diaz. In fact, apart from the two roundtable meetings, the two basically had no contact in private.

Rey Diaz is busy promoting the research and development of stellar hydrogen bombs every day, while Pang Xuelin is focusing on his Star Ring City. In addition, he has been hibernating for the past few years, and the two have no intersection at all.

What is Rey Diaz looking for at this time?

It is impossible to say that someone has deciphered his strategic thinking.

His stellar hydrogen bomb has not yet been manufactured, let alone the weird horror.

With such doubts, Pang Xuelin met Rey Diaz in the reception room of the Presidential Room.

"Professor Pang, hello!"

"Mr. Rey Diaz, hello!"

The two shook hands for a moment.

Pang Xuelin cut to the chase and said, "Mr. Rey Diaz, what do you want me to do this time?"

Rey Diaz smiled and said, "Actually, I have nothing to do. I just want to come and talk to you. I'm going to hibernate soon."

"Um?"

"The stellar hydrogen bomb requires powerful computing power. The current supercomputer level cannot support such a project. I can only wake up after the supercomputer has achieved results."

"I see."

Pang Xuelin nodded.

Rey Diaz was silent for a moment, and said: "Professor Pang, I actually know that what happened half a year ago is true... Taylor and I are old rivals, I can guess what he's thinking, and I believe he can too." It's what I thought. It's just that ETO people probably didn't expect that this matter would be taken by you to fight back. Not only did it solve the idea that the wall-facing plan might be questioned by the public, but it also put the development of ETO in trouble. Today I Come here, one is to express my gratitude to you, another question, what I want to ask is, if my plan was cracked by ETO, but ETO did not announce it, but only informed the three-body civilization, let them fight in the battle of the end I was prepared at the time, so is such a plan still meaningful?"

Pang Xuelin smiled slightly and said: "Mr. Rey Diaz, I once said that the plan is not static. Our wall-facing plan can be modified at any time according to the latest technological development of human beings. As for whether it will work or not, that is not something we have to consider. We only need to fulfill the duties of a Wallfacer, and leave the rest to our descendants. We must learn to trust them !"

Rey Diaz said thoughtfully, "Professor Pang, I understand."

Next, Pang Xuelin and Rey Diaz relaxed and exchanged views on some current international political and economic situations.

That night, Pang Xuelin and Rey Diaz had a meal together.

Early the next morning, Rey Diaz went to the hibernation center to prepare for hibernation.

Two days later, Pang Xuelin and Wade took a special plane to Xinghuan City for investigation.

A month later, Vader agreed to the request to take over Star Ring City.

In the same month, Pang Xuelin set up a graphene lithium-air battery research and development team.

Half a year later, that is, in February of the ninth year of the Crisis Era, Pang Xuelin took Cheng Xin back to China and held a more in-depth meeting with the Chinese high-level officials.

In March, China announced that it will provide further support for the construction of the second phase of the Star Ring City.

At the same time, Pang Xuelin went to see Zhuang's mother, and Li Yao and his wife.

Mother Zhuang has remarried and is living a decent life.

Pang Xuelin asked her if she would like to work and live in Xinghuan City. Zhuang's mother finally chose to refuse after considering for a long time.

In April of the same year, Pang Xuelin and Cheng Xin returned to Xinghuan City. Pang Xuelin left Wade a copy of Xinghuan Institute of Advanced Technology Development Outline for the next 30 years, and then entered a hibernation state together with Cheng Xin.
