October 3.

Huang Xiuyuan returned to his hometown from Baker Island in the Pacific.

In Chang'an City, I met Lu Xuedong whom I haven't seen for a long time. Lu Xuedong introduced him to some recent scientific research projects.

In the Guanzhong Plain in October, the autumn wind was already blowing, and the street trees on the streets and alleys were dyed red and yellow by the weather.

At the 6036 Institute under the charge of Lu Xuedong, Huang Xiuyuan saw a very strange new technology. He had previously said that Lu Xuedong, Zhang Jingjian and others have been engaged in semiconductor technological innovation research.

But the directions of the two people are different.

Zhang Jingjian focuses on the research and development of chip technology, while Lu Xuedong focuses on the application of new technologies.

Lu Xuedong took out a small bottle from a small box, unscrewed the bottle, threw the bottle into the test site in front of him.

This test site simulates wasteland in the natural environment, including weeds, stones, sand and soil, and even some residual domestic waste from human society.

After the bottle was thrown in, Lu Xuedong picked up a tablet and entered some instructions on it.

On a machine next to it, a row of equipment similar to searchlights is constantly adjusting the illumination direction, and then launching a continuous high-energy microwave to the position where the bottle falls.

Suddenly, the surroundings of the small bottle began to undergo drastic changes.

A model is rapidly "growing" at the location of the bottle at a speed visible to the naked eye.

In less than half an hour, a two-story building was grown.

"Is this your achievements?" Huang Xiuyuan looked at the building in front of him, and there seemed to be no surprises. He knew this technology very well.

Lu Xuedong nodded: "Yes, the nanorobot that can be used initially can be put into use."

That's right, this is the effect of nanorobots.

This nanorobot that sets fixed programs in advance uses high-energy microwaves as wireless charging energy, and uses small supercomputers as program main body and computing power to realize the control of the nanorobot.

As for how nanorobots synthesize compounds, this is to use the "electric field synthesis technology" of Xie Qing's team, coupled with the semiconductor technology further developed by Lu Xuedong's team, which allows nanorobots to have some of the functions in the design.

Huang Xiuyuan turned his head and asked, "How strong is the building?"

"It is stronger than ordinary reinforced concrete buildings, but it is not as strong as the material of integrated buildings. The advantage is that it is very fast." Lu Xuedong said while pulling out a document from the database for him.

Huang Xiuyuan took the file and browsed it carefully.

The nanorobot named "Creation-52" is the nanorobot in front of you, and it is also the latest version developed by Lu Xuedong's team.

This nanorobot integrates technologies in more than a dozen major fields such as nanotechnology, electric field synthesis, semiconductors, artificial intelligence, wireless charging, and wireless communication.

The small vial I just tested weighed only 10 grams. With just so many nanorobots, it built a two-story building covering an area of ​​100 square meters and 8 meters high in just 24.3 minutes.

Moreover, since it is a nano-scale structure, its strength is one small order of magnitude stronger than that of ordinary reinforced concrete buildings.

The key is that the speed is fast enough. As long as there are enough nanorobots, microwave chargers and control computers, it is not impossible to instantly build a large building.

Of course, this nanorobot is not without its shortcomings.

When Huang Xiuyuan saw the last part of the document, it was the disadvantage of this nanorobot.

To sum up, the disadvantage of this nanorobot is that its control distance is limited, it has certain dangers, its energy consumption is too high, its cost is too high, and its life is too short.

The current effective control distance is only about 170 meters. If this distance exceeds, the nanorobot will lose control, either working randomly or being silent.

This effective control distance is mainly limited by microwave charging technology and wireless communication technology.

Unlike large robots, nanorobots are currently unable to achieve long-distance control at all.

As for the danger, it is mainly microwave radiation during microwave charging, and the working mechanism of nanorobots that are inseparable from each other.

If you missed the nanorobot during work, you can't stand it for a few minutes even if you wear exoskeleton armor.

The pervasive microwave and nanorobots will quickly destroy substances within the working range.

This is mainly because the raw materials for nanorobots are either prepared in advance by the construction party or taken locally.

If it is a local material acquisition mode, then all the substances within the working range are within the utilization range of nanorobots.

Nanobots don't pay attention to it. Even if the creatures that exist within the working range are set up in advance in the computer and setting up some prevention programs in advance, they cannot guarantee 100% safety.

After all, there is a delay in the machine. The living thing is mistakenly entering the working range of nanorobots. A few seconds will be enough to destroy the skin and penetrate into the muscles and blood.

This is still a large animal. If it is a small animal, the control computer cannot detect it 100%.

"The cost is not a problem, but the service life is indeed too short." Huang Xiuyuan commented pertinently.

Lu Xuedong also spread his hands: "There is no way, microwave charging can't solve the damage to semiconductors for the time being."

At present, the service life of the "Creation-52" nanorobot can only be used continuously for about 85 hours in the laboratory stage, which is only a little over three days.

Compared with its cost of 75 million per gram, the cost performance is indeed too low.

If real estate developers in the old era used this nanorobot to build a house, they would probably lose money to their grandma's house.

This thing can only be used in specific fields for the time being, such as space garbage recycling and emergency construction of alien bases.

Of course, this is because the functions of this nanorobot are too complicated. If it is a nanorobot with relatively simple functions, the cost is not that expensive.

For example, the "silene-ultracarbon nanotubes" developed by Xie Qing's team previously used special nanorobots and combined with electric field synthesis technology to achieve rapid manufacturing.

Huang Xiuyuan returned the tablet to Lu Xuedong: "I'm still optimistic about your plan No. 43."

"Terminate labor type?" Lu Xuedong was stunned and nodded again: "In a short time, a division-based nanorobot is indeed the best choice."

In fact, the Creation 52-nanometer robot is not the most mature technology of Lu Xuedong's team. After all, the most advanced technology often represents another characteristic, that is, "immature".

Creation 43 is the type that can be put into large-scale use. Its cost is only 350,000 yuan per kilogram, its service life is about 1,300 hours, and its electrical efficiency is also good.

It is to use it separately. Lu Xuedong's team splits all the functions to be realized into 15 specific nanorobots.

When you need to use it, just follow the capture step by step, so the speed will be much slower.

It also takes about 273 minutes to build a two-story building covering an area of ​​100 square meters and 8 meters high.

"The Ministry of Aerospace should be interested."
