But these are all small things, and Tang Rui won't say anything.

Anyway, Red Lotus's computing power is there.

It's a waste not to use it.

Besides, the computing power that calculates the shape of the car is not even a drop in the bucket.

At night.

After Tang Rui finished eating, he received the data uploaded by the employee.

"Red Lotus, according to this data, make a robotic arm, remember to install the haptic feedback sensor and the neural signal conversion chip."

"Master, do you need to load the weapon system?"

"No, I don't."

"Okay, master, Red Lotus knows."

Less than ten seconds.

Honglian will get the design of the robotic arm, and the internal structure is ready-made, as long as the shape is modified according to the data.

Under the control of Red Lotus.

Nanoscale 3D printers, starting to print the bones of the robotic arm.

The hollow mesh skeleton made of the new alloy is lighter than the bones of the human body, so even if you load a little more electric equipment, the overall calculation is no different from that of a real arm.

More than an hour later.

A robotic arm is built.

Tang Rui sent a message to the employee, asking if he wanted metal skin or released skin.

There is no difference between the two.

It's just that the appearance is different.

Metallic skin is really cyberpunk.

Bionic skins are like real arms.

"Thank you, Mr. Tang, we still want bionic skin."

"Okay, come and get it tomorrow."

After Tang Rui explained to Honglian, he went to sleep.

The next day.

Tang Rui went to Lin Chao and asked him to help with the production license of electric vehicles, and then asked his private team to register the patent for the appearance of the car designed by the employees.

The next three days were less than three days.

Hundreds of employees exchanged points for electric cars, all of which were handed over to them.

Don't worry about playing cards.

Directly through the special passage, I got a green license plate from the DMV.

Everything on the company's side is taken care of.

Tang Rui took Li Shuyao to his grandparents' house to prepare for the New Year.

Compared to last year.

This year, my grandparents' health is much better.

He changed the physiotherapy mattress for two elderly people last year, which is the same principle as his physiotherapy cabin.

But he's used to strengthen his body.

And what he prepared for the two old people was to repair the body and regulate various systems in the body.

A year has passed.

The body of the second elder is stronger than before, not to mention, the common symptoms of the elderly have been cured, and even the blood pressure has been lowered, so there is no need to take blood pressure medicine.

"Xiao Rui, when are you going to get married?" Grandma had been thinking about it all the time.

He said before that things were busy, and the old man didn't rush him.

Now it's the New Year.

Began to urge marriage as usual.

"Wait two days to go to her house, ask her parents' opinions, and set a date when the time comes." Tang Rui did not shirk.

After all, they've been together for a year.

There are no conflicts and contradictions, and they get along more harmoniously.

So getting married or something, he didn't resist.

When Li Shuyao heard Tang Rui say this, she gave him a special look, which meant that there was a reward.

Needless to say, what the reward is.

Tang Rui chose a nun dress this time.

Chinese New Year's Eve.

Tang Rui received a lot of blessing messages, as well as a large number of New Year's gifts, the specific number he didn't remember.

Anyway, there are seventeen pages of the list of gift lists counted by Red Lotus.

Most of them were sent from abroad.

What antique jade, jewelry, diamonds, calligraphy, calligraphy and paintings, a lot of them are enough for him to open a museum.

Tang Rui didn't feel anything when he saw it.

Because he himself is not interested in these things, Li Shuyao is very interested in those jewelry.

Oh, woman.

Accompanying his grandparents to celebrate the New Year, Tang Rui took Li Shuyao to his parents' house for lunch and dinner on the first day of the New Year.

Then there was another meal of urging marriage, saying when the parents on both sides would meet and set the matter to a certain point.

On the second day of the Lunar New Year, I came to Li Shuyao's house.

Tang Rui took the initiative to mention marriage, which made Li Shuyao's parents very happy, and then began to talk about this topic.

"Brother-in-law, if you hold a wedding, how many tables will you have?" The eldest brother asked curiously.

Tang Rui was also stunned for a moment when he heard this question.

How many tables?

If it's just relatives and friends on both sides, that's fine, but the problem is that there aren't many people on his side.

Even if he doesn't invite people to come, there will definitely be a lot of people rushing over, and you can't rush people when you get married.

At that time, it is difficult to say whether a hundred tables will be enough to sit.

"It's really a problem, and I have to think about it." Tang Rui said solemnly.

"Actually, there's no need to make a big deal, just call relatives and friends to have a meal together." Li Shuyao's father said.

"That's not good, just get married once, and there should still be a scene." Tang Rui shook his head, at this point, he still had his own ideas.

"Brother-in-law, if there are too many people, we can take the resort down, there is enough space over there."

"Lodge? No, the grade is not enough. Tang Rui shook his head.

"Wedding City, how about a Chinese wedding?"

"Ten miles of red makeup, phoenix crown?"

When Tang Rui heard about the Chinese wedding, his eyes lit up, and he turned his head to look at Li Shuyao, wondering what she thought.

Li Shuyao was also very moved when she heard the eight words Tang Rui said.

What woman would not like the phoenix crown and the xiaxia.

The wedding dress is in front of the phoenix crown, which is not high-grade at all.

Come on.

Got it.

Tang Rui saw Li Shuyao's expression and understood.

"That's a Chinese-style wedding, but the wedding city can't do it, I'll figure out the venue."

"Brother-in-law, you don't want to go to Hengdian, just build a palace to hold a wedding."

Tang Rui shook his head, Hengdian was not in his consideration.

According to his character, if you want to do it, you can make it big.

The palace in Hengdian is enough, but the grade is not enough.

But there's no hurry.

It's really not possible, just get a piece of land and build an ancient palace complex specifically for weddings.

It's a high-profile thing to do.

But in his current situation, as long as it is not a matter of principle, then everything else is not a problem.

In a blink of an eye, it came to the seventh day of the Lunar New Year.

After the New Year, everyone started to work, and Tang Rui was also going to start getting busy.

But he hadn't had time to get his business done yet.

I was called to a meeting.

The content of this meeting is to discuss several major projects this year, namely the space station, earth orbit defense and space elevator.

These three plans are mutually reinforcing.

It can even be said that these three plans can be started at the same time, so the content discussed at the meeting is the actual construction difficulty and design indicators.

Meetings are important.

Therefore, the questions raised by everyone are also pertinent.

One such issue is the material of the cable for the space elevator.

Fortunately.

Tang Rui can give a direct answer to this question.

"On the issue of cables, we all know that carbon nanotubes, according to calculations, as long as the cable made of carbon nanotubes has a tensile strength of 70GPa, then it meets the manufacturing standard of space elevators.

At present, the tensile strength of the carbon nanotubes manufactured by Shenhong is 350GPa, which far exceeds the demand for strong materials for space elevators.

At the same time, the 80 52,000-kilometer-long cables required for the entire space elevator can be manufactured in half a year. ”

Tang Rui opened his mouth and directly solved the biggest difficulty of the space elevator, the strength of carbon nanotubes before, everyone knows it, but the problem is that if you want to make carbon nanotubes for such a long time, you can't do it at all.

But for Tang Rui, this is not a problem at all.

"May I ask Academician Tang, how is the length of 52,000 kilometers calculated? Why choose such a length? ”

After listening to this, an academician immediately asked.

It's not that it's aimed at Tang Rui, it's just asking the key questions, after all, this length also has a saying.

"According to my design of the space elevator, it can be divided into three stages, the first stage is the section from the base of the earth's surface to the airport space station, which is 36,000 kilometers long.

The second stage is the airport space station, where a huge ring is created and centrifugal force is used to create pseudo-weights that allow workers to stay at the airport for a long time.

The third stage is the 16,000-kilometre triumph from the airport space station to the trim gravity-armed satellite platform at the end of the cable.

The reason for the length of 52,000 kilometers is that the altitude of the geostationary orbit is taken into account first, and the weight of the armed satellite platform is considered secondly.

If there is no armed satellite platform, then the length of the cable needs to reach 130,000 kilometers, which is certainly not possible.

However, if the armed satellite platform is too heavy, although the length of the cable at the tail end can be shortened, it will lead to the stability of the entire platform.

Therefore, after countless simulations and calculations, the length of 52,000 kilometers is the optimal solution for the length of the space elevator cable. ”

Tang Rui did not hesitate and directly said the specific situation.

This is the optimal result obtained after many calculations by Red Lotus, and a little longer or shorter will affect the stability of the whole system.

"Academician Tang, according to you, the airport space station uses centrifugal force to create gravity, but then the mass of the entire space station will become very terrifying.

Once the space station tilts, then the cable of the space elevator will break, how to solve this problem? ”

Another academician questioned, after all, this is indeed a fatal problem, unless you can guarantee that the space station will never tilt once, otherwise even carbon nanotubes will not be able to withstand the power of the space station.

"Regarding this point, it is actually very easy to solve, that is, to separate the space station from the main orbit of the space elevator, and not to make a hard connection, only to use a soft connection.

Although this can be a big problem in terms of attitude adjustment and track control, it can be solved by using a soft connection like an electromagnetic bearing.

At present, this technology has been conquered by me, so the orbit, attitude and inclination angle of the airport space station are no longer a problem. ”

After hearing this, everyone nodded.

If so, then the technical difficulties of the space elevator project have basically been overcome.

As for the engineering difficulties, it is a matter of effort at most.

"Academician Tang, do you have any recommendations for the manufacturing location of the space elevator?" The person from the National Yuan Office asked.

Tang Rui said four words: "Mogadishu." ”
