Great Country Academician

With the experimental data of the porous liquefied DAC carbon dioxide collector, Xu Chuan returned to Nanjing University.

In the office, he flipped through the data he brought back and stared at the ceiling in deep thought.

"Tang Ran."

Coming back to his senses, he called out to the assistant room outside.

Soon, the round-faced assistant Lv Ling walked in: "Sister Ran went out more than ten minutes ago and hasn't come back yet. Professor, do you have anything to do?"

Xu Chuan nodded and said, "Then please help me contact the leaders of the municipal government and make an appointment with them."

"Okay, professor." Lv Ling responded quickly, and then asked, "Are there any specific leaders or work?"

A municipal government, especially a sub-provincial megacity like Jinling, must have different responsibilities for different jobs. Leaders who can directly connect with corresponding fields are naturally more efficient.

Xu Chuan thought for a while and said, "Industry and environmental protection."

"Okay, professor, are there any other jobs?"

Lv Ling looked at Xu Chuan with some surprise. The word environmental protection did surprise her. When did the professor start studying this?

"Not for now."

Xu Chuan waved his hand, his eyes fell on the experimental data on the table, and he pulled out a stack of manuscript paper from the drawer.

Although the current purification speed of porous liquefied DAC carbon dioxide collectors is not very fast, the quality can be compensated by quantity.

Especially in large cities with tall buildings, in theory, it is possible to expand the purification area by occupying one floor or the outer wall of several floors.

He plans to do a pilot to see whether investing a large number of porous liquefied DAC carbon dioxide collectors in densely populated urban agglomerations can change the ecological climate of a large city.

Jinling is a good choice. Although the initial investment may be too large, Jinling has sufficient economic strength.

And for a city, especially a city like Jinling that is like a "furnace" every summer, it is undoubtedly worthwhile to improve the temperature and make it more livable.

It's very simple. Cities are the result of population and industrial agglomeration. The population determines the development of cities. The impact of a large population is huge.

Not only the economy is more developed, but also the development of industry, the number of infrastructure, the richness of cultural and sports entertainment, the level of medical education and other aspects will have a great impact.

After the first batch of Dawn Fusion Reactor was piloted in Jinling, the city's permanent population has exceeded 12 million, and is still rising rapidly.

If Jinling can be made more livable, I believe the municipal government will be happy to see it and willing to pay for it.

However, what Xu Chuan did not expect was that he sent the invitation to the municipal government through his assistant at noon, and before four o'clock in the afternoon, the heads of the two major departments of industry and environment in Jinling City hurried to Nanjing University.

Carrying a textbook, he finished a big class, and just rushed back to his office from the teaching building when he received a report from his assistant.

"Professor, the two directors of the Municipal Bureau of Industry and Information and the Bureau of Ecology and Environment have arrived."

Hearing this, Xu Chuan was a little surprised: "So soon? Where are they?"

Lv Ling quickly replied: "In the reception room."

Throwing the textbook on the desk, Xu Chuan casually asked: "How long have they been here?"

"About half an hour."

"Please ask them to come over."

"Okay, professor."

Lv Ling responded and walked out quickly.

After a while, two middle-aged and elderly men in suits and leather shoes walked in quickly.

"Sorry to have kept the two leaders waiting for so long. I was teaching students just now." Seeing the two city leaders coming in, Xu Chuan stood up and greeted them with a smile.

"No, Academician Xu, you are too polite. Teaching and educating people is the foundation of the country. We have just arrived not long ago."

The middle-aged man with gold-rimmed hairline in front laughed and came up, extending his hands enthusiastically: "Hello, Academician Xu, I am Han Zizhen, temporarily serving as the director of our Jinling Municipal Industrial Information Bureau. I heard that you invited us to discuss work, I hope I am not late."

Xu Chuan smiled and shook hands with Director Han, and then greeted the director of the Ecological Environment Bureau next to him.

"Director Han, Director Li, please sit down first."

Gestured to the sofa next to him, Xu Chuan sat down with a smile.

After a few pleasantries, Lv Ling came in with tea, poured a cup for each person, and then quietly left, closing the door of the office.

After taking a sip from the teacup, Xu Chuan looked at the two directors and said, "I'm bothering you two leaders to come this time. The main reason is that I have a new technology, or a new idea, and I want to do a pilot in Jinling City."

When the two directors heard about the new technology, their eyes lit up and they quickly said, "Academician Xu, please tell me. If Jinling can help, we will do our best."

This new technology, no need to think too much, it must be amazing.

With a smile, Xu Chuan handed over the experimental data of the porous liquefied DAC carbon dioxide collector that he had prepared on the coffee table before, and said,

"I didn't expect the city to be so efficient. I remember that I sent a message through my assistant at noon, and you arrived in the afternoon."

"I haven't had time to make the relevant project plan, but I have a copy of the experimental data here. You two can take a look first."

Han Zizhen laughed, took the experimental report with both hands, and said with a smile: "Serving the people is what we should do."

On the side, Li Jian from the Ecological Environment Bureau came over, took a look at the information on the experimental report, and looked at Xu Chuan with some curiosity and asked.

"Porous liquefied DAC carbon dioxide collector? What is this? Can Academician Xu explain it to us briefly?"

"Of course."

Xu Chuan nodded and said with a smile: "Simply put, it is a device that can absorb and capture carbon dioxide from the air and convert it into oxygen, starch, glucose, gasoline, graphene and other materials."

"It uses the technology of combining ion exchange membrane + isophorone diamine, and is driven by electricity to capture carbon dioxide in the atmosphere. At a concentration of 400ppm, the ability to remove carbon dioxide in the atmosphere exceeds 99%!"

"It is more than twenty to fifty times the ordinary carbon dioxide adsorption technology or materials on the market. Even the best amine materials are only about one-fifth to one-tenth of it."

Across the sofa, Han Zizhen's eyes lit up when he heard this introduction.

Adsorbing and capturing carbon dioxide, converting it into industrial products such as oxygen, starch, gasoline, and graphene, turning waste into treasure, it's a good thing.

If other people proposed these concepts, he, the director of the Industrial Information Bureau, might still consider questioning whether this technology can really be commercialized.

But the person in front of him, there is no need to worry about it.

After thinking for a while, he quickly said: "In other words, this set of equipment can cooperate with the industrial system to treat carbon dioxide emissions to the greatest extent."

Across the sofa, Xu Chuan nodded and smiled: "It is undeniable that the removal of carbon dioxide in the industrial system is indeed its value, and its efficiency will be higher than other carbon dioxide removal systems."

"But in my opinion, its greater value is not here, but in another direction."

Hearing this, Han Zizhen and Li Jian, the two leaders of Jinling City, looked over with some curiosity and interest.

"Another direction? Which direction?"

Xu Chuan smiled, his eyes fell on Director Li of the Ecological Environment Bureau, and said: "I believe the two leaders are also very clear that with the development of industrialization and the large-scale emission of carbon dioxide, the impact of the greenhouse effect has become more and more serious since the 21st century."

"Not to mention the various problems it brings, such as global warming, melting of polar glaciers, and rising sea levels, just in the city, it can be said that the situation is getting hotter every year, which is enough to make people miserable."

"The porous liquefied DAC carbon dioxide collector may not necessarily completely reverse the climate of the entire earth, but for the high concentration of carbon dioxide in the city, it theoretically has a certain mitigating effect."

"Although the high temperature of the city cannot be completely attributed to greenhouse gases mainly composed of carbon dioxide, when these greenhouse gases are greatly reduced, the temperature of the city will definitely decrease accordingly."

"In short, this system can play a significant role in regulating the temperature in the city, and it can also produce a certain amount of oxygen, starch, light-chain gasoline, glucose and other carbon compounds."

"And the only thing that needs to be paid is It's just some electricity that is so cheap that it can't be any cheaper now. "

"This is currently on the market, even in the world, no country or any company can do it."

Looking at the two in front of him, Xu Chuan asked with a smile: "How about it, is the Jinling Municipal Government interested?"

Listening to Xu Chuan's explanation, Han Zizhen from the Industrial Information Bureau, who had briefly read the experimental data report in his hand, thought for a long time and asked cautiously:

"Although I don't understand things in the technical field, I think if I want to change the carbon dioxide content of a city as a whole, I'm afraid the number of carbon dioxide adsorption devices that need to be deployed should be not small, right?"

Xu Chuan nodded and said: "This is for sure. According to the current experimental data, if we want to have a certain impact on the atmosphere of the entire Jinling City, we may have to transform most of the high-rise buildings in the city."

"At least use the first floor of these buildings or transform the external areas of multi-story buildings."

"Of course, this refers to non-residential communities, mainly those buildings with more than 30 floors in the city center."

Hearing this, Han Zizhen couldn't help but smile bitterly.

If it is only the high-rise buildings in the super-high commercial centers that are being renovated, it would be easy to say. After all, there are only about 30 or 40 high-rise buildings over 200 meters in the entire Jinling City.

However, a building with about 30 floors is almost the backbone of a city.

Whether it is an ordinary commercial building or a residential building in a residential area, many of them are around or above this number of floors.

Even if we leave aside non-residential areas and only renovate commercial buildings, the amount of work is so huge that he cannot calculate it in a short time.

There are probably more than 500 buildings with 30 floors and about 100 meters in Jinling City.

Especially after the completion of controlled nuclear fusion technology, the Dawn Fusion Reactor was the first to be piloted in Jinling, and a large number of super-high-rise buildings have been built in the past two or three years.

Taking a deep breath, Han Zizhen asked: "Academician Xu, how much does this carbon dioxide adsorption capture device cost?"

Xu Chuan shook his head and said, "I'm not sure about this. However, in the porous liquefied DAC carbon dioxide collector, the most expensive part is the material that absorbs carbon dioxide. The others shouldn't be that expensive."

"As for the carbon dioxide adsorption material, that is, ion exchange membrane + isophorone diamine, according to the current cost, it is about 300 per kilogram."

"One kilogram of isophorone diamine can cover an adsorption area of ​​about two square meters. And each square meter can treat about one hundred cubic meters of air per hour."

"But isophorone diamine is not disposable, it can be self-circulating. Simply put, it can be used for a long time after being invested once. According to the current experimental data, it can run for about ten years."

"The specific cost price, I'm afraid, will be calculated later."

Han Zizhen nodded and silently calculated it in his mind.

Three hundred yuan per kilogram can cover two square meters. According to the area of ​​20,000 square meters of a commercial building, even if only the exterior wall is renovated, the carbon dioxide adsorption material alone will cost at least 300,000.

It doesn't sound like much, but this is just one of the 'parts' in this equipment, and it only renovated one floor of a building.

If there are 500 buildings in Jinling City that are more than 100 meters, that is, more than 30 floors, and each building is renovated with one floor, then the adsorption material alone will cost at least 150 million.

Although the person in front of me said that it is the most expensive part of the whole set of equipment, other parts, especially this kind of high-tech equipment, are probably not much cheaper.

Overall, if this project is carried out, it is roughly estimated to start at tens of billions.

This number is too large, and he can't make the decision alone.

Moreover, this project will not see benefits in a short time. Strictly speaking, this is a public welfare project for people's livelihood.

Although Han Zizhen believes what the person in front of him said, carbon dioxide is a resource and can also be converted into starch, gasoline and other materials.

But overall, the main purpose of this project is to change the atmospheric environment of Jinling City and reduce the temperature in the urban area.

Whether it is worth it, I am afraid that there will be some arguments on the side of the municipal government this time.

Of course, although the investment is large, if it can really be done, then Jinling will undoubtedly become the most livable city in the country, and it can even be said that there is no other.

Because the suitable living climate is fatally attractive to ordinary people.

Who doesn't want the temperature outside to be only 25 or 26 degrees in summer?

This is to create a super city that is most suitable for human habitation.

Suddenly, an idea flashed through Director Han's mind.
