"Suppose that due to some misoperation or equipment failure or system failure, the high-intensity sunlight reflected by the reflective satellites in the sky deviates, and the light of 400 times the natural light intensity is not focused on the ground receiving device, that is, the battery pack of 120 square kilometers, then ...... Oh my god...... Academician Shen, you must have imagined this situation, right?" Wu Xinping raised his worries very worriedly.

Shen Qi said solemnly: "Then it will cause a huge disaster in the area where the light is off. ”

Wu Xinping's heart beat faster: "I am studying the environment, I have a very shallow understanding of the satellite system, I believe that it is almost impossible for our satellite system to have problems, but in case, ...... Even if there is a 1 in 10,000 probability that something will go wrong, how can we deal with it?"

Shen Qi became more serious: "There is no better way than to evacuate in time. ”

"In fact, we can all imagine that if there is no specific ground device to receive ultra-high intensity sunlight, then all life on the ground in that area will face the catastrophe...... Yes, if such a disaster happens, we will have no choice but to evacuate in time. Wu Xinping inexplicably felt a chill, and he asked: "Academician Shen, there is a sentence that I don't know whether to say or not?"

"Please. ”

"Assuming that our 120 reflective satellites are successfully launched into space and successfully operated, is it possible for human active operation to make the light reflected by the constellation of satellites 400 times the natural light intensity precisely illuminate a specific area outside the Northwest Base?

"There is such a possibility. I mean, it can be done technically, but we're never going to do it. ”

"This ......," Wu Xinping said with a cold sweat, "Legend has it that in ancient Greece, Archimedes used a huge and special mirror to reflect sunlight and burned the invaders' warships from a distance. Can I understand that under certain extreme circumstances, the 120 reflective satellites of the 'Point of Light' will become a kind of ultra-destructive optical weapon? With the current level of human defense, there is no effective means of active defense to resist optical attacks from space except for escape. Unless, the first to destroy the constellation of reflective satellites in the sky. ”

"Old Wu, this idea of yours is very dangerous. The 'Point of Light Project' is a project for people's livelihood, not a weapon of war. Shen Qi firmly denied that the "Point of Light" was used to strike at the enemy's dangerous concept.

"Academician Shen, do you know that the construction of the Three Gorges Dam did not use such a large number of well-equipped military forces......

"Lao Wu, I think you should focus on improving the various emergency plans mentioned in the meeting. Of course, if the reflected light is out of line, then a contingency plan should also be developed, mainly considering how to evacuate the people in the light-receiving area in the shortest possible time. ”

"Then I would like to ask Academician Shen, when the reflected light misalignment occurs, how much time do we have to evacuate people from the light-receiving area?"

"7 minutes, 7 minutes maximum. Shen Qi gave a data, he obviously did in-depth research and calculations on this kind of sudden event with a very low probability but theoretically possible.

Before Shen Qi, hadn't anyone else done research?

Of course, Academician Han's calculation is 24 minutes.

On the basis of Academician Han, Shen Qi shortened by 17 minutes.

Wu Xinping's brows tightened, and he said: "The area of the battery pack used to receive reflected light in the northwest base is 120 square kilometers, which is a little larger than the area of the capital's Dongcheng District + Xicheng District. Assuming that this 120 square kilometers of area is not laid with high-tech battery packs that meet the standards, then it will be affected. ”

"Assuming that 120 square kilometers is a circular area, then its radius is 6.2 kilometers. Running from the center of the circle to the outside of the circle is the longest distance. That is, when a disaster strikes, the person in the center of the circle is the most dangerous, and he has a maximum of 7 minutes to run to the safe area. And this is almost impossible, because the men's 5000m world record is more than 10 minutes. ”

"So we have to make sure that there is enough transport in the areas that are likely to be affected so that everyone can be safely evacuated. The problem is that we can't accurately predict where the light will deviate. ”

Therefore, every inhabited area in China must be equipped with sufficient escape vehicles and open up special escape channels to prevent congestion during escape. Or, in every inhabited area of China, underground shelters are built. Regardless of the contingency plan, the cost will be astronomical......"

As a rigorous scholar, Wu Xinping's concerns are justified.

He said more than ten years ago that the "Light Point Project" can't be done.

Shen Qi has considered all the issues that Wu Xinping is worried about.

Shen Qi's attitude was: "Old Wu, please believe me, I will use a new technical means to ensure that the problem you are worried about will not happen." This new type of technical means is being studied, and the premise that the reflective satellite can be launched into space is that the new technical means can be studied and verified OK to ensure 100% safety. Heaven or earth, space or earth, the basic rule that we must always abide by is that safety comes first. ”

Regardless of whether Lao Wu believes Shen Qi or not, everyone's work has to continue.

Shen Qi returned to the capital from his trip to the northwest, and he had a lot of work to do, and every job was particularly important.

The core part of the "Point of Light" project is located in geosynchronous orbit, and the smooth operation of ground power stations depends on the constellation of reflective satellites in orbit.

One hundred and twenty reflective satellites will form a huge space mirror in synchronous orbit, with the change of the curvature of the earth's rotation angle, the reflective satellite group will accurately focus the reflected light on the ground in the 120 square kilometers of battery pack light-receiving area, and the solar power station with a capacity of 50 million kilowatts will begin to generate electricity to ensure the economic construction and people's livelihood needs of the northwest region.

Wu Xinping's concern is what if the reflected light of the satellite constellation deviates?

Even if the latitude and longitude deviate by one degree, it will cause irreparable huge losses.

Therefore, the error-proofing mechanism of the satellite control system is particularly important, more important than power generation.

Shen Qi finally understood the reason why Academician Han, the chief scientist of this project, had a heart attack.

If the "Light Point Project" is to operate safely for a hundred or several hundred years, until new energy sources that are more efficient and environmentally friendly than solar energy appear, and thus terminate the "Light Point Project", then the core designers and commanders of this project will undoubtedly be the national heroes who have made great contributions.

If the "Point of Light" leads to a major catastrophe in the course of operation, then don't talk about any merits, just wait for sanctions.

Of course, the satellite control system of the "Light Point Project" has set up an error-proofing mechanism, which embodies the wisdom of China's top scientists.

If the system security score of China's four major banks is 100 points, then the safety score of the satellite control system of the "Light Point Project" is more than 10,000 points.

Theoretically, it is impossible to go wrong with the satellite control system of the "Light Point Project".

Wu Xinping is an important person in this plan, but his level is not high enough, and it is difficult for him to access the highest-level secrets of the "Light Point Project".

The reason why Shen Qi was able to calculate "7 minutes", and he shortened it by 17 minutes on the basis of Academician Han's "24 minutes", was because Shen Qi had access to the most core confidential data.

Shen Qi is still a little worried, is the error-proofing mechanism of the "Light Point Project" satellite control system absolutely safe in nature?

After all, Shen Qi did not participate in the design of the satellite control system of the "Light Point Project".

The 120 reflective satellites have not yet been launched into space, but Shen Qi has the conditions to verify the error-proofing mechanism of the satellite control system, in his own way, a completely new way.
