In the lead-gray workshop, there is a glass room in the corner, and more than a dozen mechanical arms poke out from the top and side, some end of the welding gun, some are manipulators, and some are holding wires. From time to time, sparks arc through the room, and a device is being assembled at a speed visible to the naked eye.

There are more than a dozen people outside the room, all wearing AR glasses, and in their AR vision, the assembly process of the device is presented in real time with 3D images. Every screw, every solder joint, as their gestures zoom in and out, the relevant data is also identified in the field of vision.

This is the D21st day of the Springboard project, which is the 21st day of their official launch of the project. After completing the theoretical design of the 1 MW VASIMR and the verification of each core component, they entered the actual machine manufacturing stage, and if the prototype was no problem, they created the feat of building 1 VASIMR in 1 month.

This is not only due to GEI, but also to this set of "robot workshop", which is a further development of Yi Liyan on the basis of the robotic arm. Relying on strong intelligence, a complex device that requires various processes can also realize the fully automated production of robots, and now her power armor assembly workshop is this.

It's a pity that the "robot workshop" is completely invested regardless of the cost of work, and the cost is hundreds of millions, otherwise it will be released, and the global robot manufacturing industry will usher in a major earthquake.

Two or three hours later, an engine about one meter long and half a meter in diameter lay quietly in a glass room, and the VASIMR, codenamed "Fuze", was finally launched. At this moment, all the members of the project team felt their heartstrings stirring and felt like crying.

"Wait and cry again, pull it out, and get ready for a test drive!" Lou Xinghai held back his mood and said, and then patted the little fat man Dongfang Sheng with an unbelievable face: "It's up to you!" ”

Dongfang Sheng shook his head, and his eyes burst out: "Absolutely no problem!" The physics of VASIMR are simple in itself, and I have also optimized the coils. Definitely light up! ”

"It's not enough to just light up, we have to see if we can reach 1 megawatt of power", Vasily is playing soy sauce, gesturing strange gestures as he says, probably still pondering the problem of the track. ”

The engine sank under the glass house, and then was carried along the track to the workbench outside the house, where two mechanical arms lifted the nearly 200-kilogram engine and moved it to the flatbed tram, which was like a flying carpet without making a sound. Silently delivered to the test bench in the center of the workshop.

The shield was raised to cover the test bench, but everyone's AR glasses showed you looking at the engine up close from all angles. With Lou Xinghai's order, Dongfang Sheng clicked the "start" button in the air with a slightly trembling finger.

At first there was no response for a second or two, but gradually, the buzzing air oscillated sound, getting louder and thicker. And in the picture. The blue flame appeared in the vent of the engine, brighter and brighter, denser and more showy.

0.1、0.2、0.3…… 0.9、1.0、…… 1.3.、1.4……

Look at the numbers that are constantly beating in the AR field of view. Finally, it stabilized at 2.2, Dongfang Shengsheng blushed and screamed: "2.2 megawatts!" I made the most of my design! ”

The 2.2 MW VASIMR can provide 5 kg of thrust, which looks pitiful. It can continue to accelerate in space, and speeds of more than 100,000 kilometers per hour are not a problem.

Others began to wipe their tears, 21 days! Tell outsiders. They built a 2.2 MW VASIMR in 21 days, and they would definitely be scolded for talking in a dream, but they did it!

Relying on all the necessary equipment, readily available materials and materials, GEI's infinite wisdom, and robots that can do all the manual work, the speed of scientific research has been increased to a terrifying level that makes people's scalps tingle.

Of course, they did not come this step comfortably, and in these 21 days, in addition to sleeping, eating and necessary physical exercise, they worked 18 to 20 hours a day, and they also fought to the limit.

Miracles were happening before their eyes, and even greater miracles were beckoning to them. 2.2 MW VASIMR is just around the corner, is 10 MW or even 20 MW VASIMR far away?

Dongfang Sheng wiped the tears that flowed to his cheeks and said, "I have to tell Xiao Xia!" ”

"I saw it", Xia Ming's voice sounded in the workshop, trembling like Dongfang Sheng: "I saw it, we did it, thank you, thank you!" ”

"This is just the first step", Lou Xinghai said solemnly: "And it's not finished yet, the next thing is to depend on Lao Yang." ”

Vasily nodded: "Yes, even if you get the solar cell, you can't cope with the appetite of 2.2 megawatts VASIR, you can only keep it at the level of 1 megawatt." ”

Xia Ming smiled: "I believe in Lao Yang, I believe that he will bring us a second miracle"

Everyone smiled with relief, yes, since they can create miracles, of course Lao Yang can too.

"No, that's not ...... enough"

Yang Bin didn't pay attention to the news push in the AR glasses at all, he had signed an agreement, his wife and son were all sent to the research institute, as for the photovoltaic company where he originally stayed, he had made a lot of contributions to technology in the past two years, and he felt that he was benevolent and righteous, and there was no psychological burden. When the boss wanted to keep him, he asked a question, and the other party respectfully sent him away, and stammered that he would have any business to help the village in the future, and the sentence was: "Can you get me a laboratory for 300 million?" ”

After more than half a month, his progress is also extremely fast, and Semprius's four-junction gallium arsenide solar cells have been copied by him. Coupled with the intelligent management program jointly written by Xia Ming and Lin Cheng, as well as the automatic control system designed by Yi Liyan, when the customized lens set arrives, he will be considered to have completed the task in a week at most.

However, he was not satisfied, after more than half a month, he felt that Xia Ming had devoted almost all his efforts and resources to this project, such as the lens group. Xia Ming accepted his suggestion in its entirety, and at the same time asked Mitsubishi of Japan, AMS of Germany and Reddy of China to customize, just to improve the fault tolerance rate.

Just to prevent anything else on the lens group, he is willing to spend tens of millions more, Yang Bin feels that if the things he takes out are just barely improvised, he will be too sorry for Xia Ming and his conscience.

He didn't have much ideological consciousness and moral standards, and he felt that he couldn't do such a thing as a soldier dying for his confidant. But the bottom line of reciprocating the peach is as solid as a dam in his heart.

Barely exceeding the 30% conversion rate, or achieved under advanced intelligent management, although this has broken through the results of the previous research institute, and can earn a lot of praise when taken out, but even the limit of the triple junction gallium arsenide has not been reached, and it is far from the blueprint of Semprius, which shows that his mastery of the four junction technology is not good enough.

If you want to master the Four Knots technique, you have to do a lot of basic experiments, which belongs to the material field that he is not familiar with, but it can be transferred to the person who looks smaller than Xia Ming. But she is a female student with a double doctorate.

After Yang Bin forwarded this topic through artificial intelligence, he was still unwilling and began to wonder whether more improvements could be made in the original three-junction gallium arsenide technology.

An idea came to mind irrepressibly, ten years ago, when he was just starting out and provoked the research group alone, he challenged one of the most advanced technologies at that time, and although he failed, he also had a lot of experience. Ten years later, no one has been able to break through this technology. Can he try again?

"GaN indium solar cells?"

In the standard AR scene, Xia Ming, Xiaotang and Yang Bin got together, and when Yang Bin talked about this, Xia Ming, who didn't know much about materials, was confused.

Xiaotang explained: "GaN is recognized by the scientific community as a third-generation semiconductor material. The first generation is silicon, the second generation is gallium arsenide, the third generation is gallium nitride, and there are materials such as diamond. As for graphene. Although there is a fourth-generation statement, everyone's opinions are still very different. ”

It's so awesome, Xia Ming searched. I immediately understood the value of gallium nitride.

SiliconEveryone knows that modern semiconductor technology is based on silicon. But there are a number of natural flaws that make it unaffordable for future semiconductor development, and this sign became clear when gallium arsenide appeared.

Gallium arsenide has been widely used in the military and scientific research fields, gallium arsenide semiconductor in the operating temperature, photoelectric conversion rate, resistivity and other aspects of the comprehensive surpass silicon, if it is not for the highly toxic elements, production pollution, high cost, its application will not be limited to specific fields. For example, the oscillation frequency of silicon semiconductors is 10 GHz, and the heat generation is already difficult to cope with, but gallium arsenide can easily achieve more than 20 GHz.

Compared with gallium arsenide semiconductors, gallium nitride semiconductors have a stronger photoelectric conversion rate and a lot better performance in all aspects. In recent years, technologies such as wireless charging have been hyped up on the basis of gallium nitride semiconductors, and coils made of gallium nitride provide the possibility for large-scale commercial applications of wireless charging, and are also the key to improving terahertz imaging resolution.

GaN semiconductors have also entered the daily field, such as LED lamps, LED lamps made of gallium nitride semiconductors, which are brighter and consume less electricity. And such gallium nitride elements are only a primary product with many technical defects.

"Covering the triple junction gallium nitride with indium film can achieve full-frequency solar conversion, and the theoretical conversion limit is 76%. Now that components are available, gallium nitride wafers are produced by manufacturers in China and Japan, and although they are expensive, I think it is worth it. The conversion rate of the solar cells should be close to 40%. ”

Yang Bin's words set in motion Qianyan's assessment: "If the energy is increased by 30%, VASIMR can operate at 1.3 megawatts of power, which will shorten the voyage time from 90 days to 75 days." ”

She added another development: "Vasily has a plan to orbit Mars and use Mars' gravity to make a wave, which can be shortened to 68 days, which I think is feasible." ”

This is already very close to the 60 days that Xia Ming asked for at the earliest, and Xia Ming said: "Okay, then take the gallium nitride route." ”

Xiaotang said: "I also improved the manufacturing process of graphene to help Lao Yang complete the triple junction of gallium nitride." ”

On the D23rd, Xiaotang handed over all the information of another improvement to Qianyan for sealing.

"My protein macromolecules are becoming more and more like bio-making machines, they are like spinning silk, weaving graphene structures layer by layer under the action of an electric field. Today I did another edit of the DNA of 15, and it became 16, and they weaved the graphene to a size of 60 square centimeters in two hours, and then stopped because they ran out of splits. ”

"This looks like a new process that will disrupt all nanomaterial production, with an estimated cost of less than $10 per square centimeter. And because of the editable nature of the weaving process, graphene conduits, graphene transistors, and other components can be directly manufactured. The graphene revolution is now in my hands. ”

"Semiconductor devices made of graphene catheters and graphene transistors can provide more powerful and more precise tools for Liluo to observe human neural movements, and can be used as devices to connect human neurons, and brain-computer interface technology has a reliable foundation. For all the graphene applications that everyone is looking forward to, I can start testing. ”

"Even Qianyan can use graphene as a conductor of QNI, so that the neural quantum effects of each synapse can be connected, and her ability will go to the next level."

"Unfortunately, I don't have the time, these technologies are meaningless now, and what I need to find is a more reliable process for triple or even quadruple GaN."

Xiaotang's oral statement was also used as top-secret information and sealed by Qianyan.

On D24, in Yang Bin's laboratory, the robotic arm held a band-aid-like soft piece without wires, directly emitting a dazzling white light to illuminate Yang Bin's workbench.

The coils etched on the multi-layer GaN LED components, which correspond to the GaN conductors on the laboratory power supply to achieve wireless charging, are just a small test for Yang Bin to verify the reliability of the GaN components.

Wireless charging is not a black technology and has been mature for many years. However, in the past, it has been subject to problems such as transmission distance, radiation, and thermal resistance, and it has been applied in some low-energy fields, and there are still many problems with wireless charging as power. The reason for this is that wireless charging requires innovation across the entire semiconductor industry.

While researching gallium nitride as photovoltaic cells, Yang Bin also experimented with the direction of gallium nitride semiconductors and came up with a bunch of process technologies. Such a technology, in addition to providing him with a little convenience for the time being, was also sealed by Qianyan.

Just as Xiaotang is thinking about four-junction gallium nitride wafers, Yang Bin is thinking about gallium nitride solar cells.

Yang Bin understands gallium nitride, and although he hit his head in front of gallium nitride ten years ago, he knows where the difficulties are. Now he has Qianyan as a staff officer, and every difficult point will be given to him to find out what others have tried to do, as well as the implementation methods of similar technologies, and bring him a steady stream of inspiration. He was completely planted with a pair of wings, and the once impassable mountain bowed his head a little below him. His progress is fast and he can't be distracted.

When Xia Ming saw these sealed materials from Qianyan and knew that the two of them had pointed out the technology tree that subverted the entire materials and semiconductor industry on the two backbones of graphene and gallium nitride, he was both surprised and helpless.

This is really Hu Lai's science and technology tree, when he scratched his head for energy technology, he made a bunch of black technologies in the field of materials and semiconductors, and commercialized these technologies, he can build a new business empire in the fields of materials and semiconductors, but now, he doesn't have that time. If the Springboard project fails, none of this technology will be meaningless. (To be continued.) )

PS: Thank you Fanta! But it's a bit of a ...... for the first alliance leader to come here like this I don't know what to say, anyway thank you for your support! You can only continue to code words in return.

There is only one shift today, and then two shifts will be sought.
