Facing Hu Lao and Sun Lao, Ji Zhen still had reservations. But in the face of the chief, Ji Zhen began to speak in his own real way, expressing his foresight and overall situation.

The chief has never been with Ji Zhen, so the consideration of Ji Zhen's character comes from the document, and it is inevitable that there will be a sense of unreality in his heart.

And Ji Zhen's external performance is the identity of a scientific researcher, which is very tall in the academic world. But in the hearts of people like the chief, who have laid out the whole country, it may not be so sacred.

In the hearts of the leaders, they may have a feeling of braggadocio about what Ji Zhen said.

Therefore, the space city plan that Ji Zhen said is actually to change the inherent concept in his heart in front of the chief, so that his own words have more weight in the chief's heart.

China itself has a large population and is too large, and every policy needs to be considered repeatedly and holistically. There is still a contest between various interest groups, and before the policy is actually implemented, it will take time to conduct pilot research.

It can be said that the implementation of every policy takes a long time to consider and pilot before it is truly implemented.

Some policies are still going smoothly, while others will have a lot of problems when they are implemented in reality.

The situation in China is too complicated, which is why many policies change frequently, because they have to adapt to the current social situation.

Now that China is still on the earth, the policy situation is already so complicated, and when it enters the era of anti-gravity and the space age, the population is even larger and the policy is more complicated.

At that time, it was really a matter of affecting the whole body, and we should be even more cautious about policies.

Therefore, Ji Zhen wants to plant a seed in the chief's heart and tell about the future development of the space city. Otherwise, it is inevitable that some people will have other thoughts, what to play to transform the planet, what to play to colonize the planet, it is all floating clouds.

It's like the whole of China has only developed Beijing, and other provinces, autonomous regions and cities, even the neighboring Hebei and Tianjin, are wastelands that no one has developed and lived in and needs to be reclaimed and built, but they want to go on an expedition to Australia and America to immigrate to mining, which must be a brain disease.

Ignoring the rich and vast solar system and thinking about interstellar expeditions can really only be seen in science fiction.

There is often a world of difference between reality and reality.

"Ji Zhen, you value the space city very much! Can you tell me more about that? ”

The brains of genius demons are always different from others, and in the eyes of the chief, Ji Zhen is this kind of genius demon.

Ordinary people can only see in front of them, but visionaries can see five years from now, or even ten years from now. And Ji Zhen, a person who arms himself with IQ and knowledge, sees it even further.

In the eyes of the chief, Ji Zhen's thinking is at least twenty years ahead of this society. Think about the time when their leaders were still being shocked by his western development plan, human dormancy technology, and life enhancement technology, and people were already focusing on the space cities of outer space.

"Okay, I'll give you a detailed explanation. In fact, space cities are not as difficult as imagined. Even without gravitational technology, space cities can be built, and the technical limitations are not too great. The rotation of the space city simulates artificial gravity, which is not so difficult to do. ”

"The space city is not fragile, and there is a shield layer with a thickness of more than 2 meters on the outside to block radiation and impact, plus air tightness, which can be said to be the standard of three-proof bunkers. Condenser mirrors, photovoltaic arrays, and radiators in space cities can be folded when necessary. ”

“···”

For the space city, Ji Zhen still has a lot of thoughts and what the chief said, because he has the fact that he has personal experience.

A long time ago, he traveled through the world, and he entered the world of "Interstellar", where the earth had been swept by blight, and the entire earth could not grow crops.

At that time, people built space cities.

"To sum up, without the development of anti-gravity technology, space cities can only be regarded as an idea, and the cost is too high. But the breakthrough of anti-gravity technology, as well as the breakthrough of nuclear energy technology, super-large space cities, are not difficult to build. ”

Ji Zhen's explanation does not have profound knowledge, he goes deep and simple, and tries to explain it to the chief in popular language.

This matter, in Ji Zhen's opinion, is indeed to be prepared.

The pattern of the future world will certainly not be as simple as a map of the world, the five permanent members of the Security Council, and more than 100 other countries today, but the thousands of independent administrative corpses scattered in the solar system, which are unprecedentedly diverse and complex.

The economic system will also be very different, with precious metals, precious stones, rare earths, and communication delays causing problems for trans-satellite commerce.

"The greatest significance of space cities is to build a livable environment in space without occupying the land of the planet, and to meet the demand for land and resettle the population. And there are as many asteroids and lunar minerals as raw materials. ”

"It's not a joke, it's better to go to the South China Sea to fill in coral reefs in the future than to build a city in space, which is environmentally friendly and funny, and can be self-sufficient."

Ji Zhen's words are very popular, which is very appetizing to the chief. Listening to it, the chief felt that Ji Zhen's words were full of temptation, and this temptation was not vain, it seemed very real.

It was as if he was right in front of the chief's eyes, and he could reach out and touch the entity.

"Wait, Ji Zhen, the cost of building this space city is very expensive, right?"

Ji Zhen smiled, when a person considers the cost, it means that he is tempted. Because the only thing that hinders the project is the cost, as long as the cost problem is solved, the project is almost passed.

Of course, the space city is certainly not so simple, but this is the first step of Ji Zhen's intervention.

"Not really."

Ji Zhen shook his head and raised his first finger, looking very calm.

"First, when building giant space structures such as space cities and space-based solar power stations, there is no doubt that a completely reusable launch system that is much cheaper and faster will be used, such as the BFR super rocket under development by SpaceX, which is 150 tons in low-earth orbit when fully reusable, and the launch cost is less than $10 million."

"Second, space cities can be manufactured in sets, and it doesn't matter if they are exactly the same, there is no need to pay attention to individuality, so they can be manufactured in batches."

"Third, space cities and space-based solar power stations are mainly built with materials from the moon and asteroids, which are gravitationally located on the moon and asteroids, with low escape speed, convenient take-off and landing, and much lower transportation costs than the earth. Launching materials with an electromagnetic launch system is even cheaper than any rocket. ”

"Fourth, artificial intelligence and automation are explosive developments, and even Foxconn has begun to replace workers with robots, which has greatly improved productivity and also greatly reduced costs."

Ji Zhen's four fingers shook in front of the chief, "Each of the above four can greatly reduce costs, and the cumulative productivity and cost are fully bearable." Coupled with the current breakthrough in anti-gravity technology, the cost is already very low. ”
