    Cheng Yuan doesn't care much about the problem of cheap production of robots. After all, these things have long been prototyped, and the most important intelligent control system is also helped by Xiaolan. Alfonso and others are just reverse research and development of the prototype robot and carry out some material aspects.  It's just a simplification, and it's not too difficult. The only thing worthy of praise is that it takes faster time to produce results.  What Cheng Yuan is really concerned about is actually nanochips and the supposedly relatively mature 5G mobile communication technology. Because these technologies did not borrow much from Louis, but were developed by the disciples themselves using the original technology of the earth.  of.  "However, these two developments have little to do with Alfonso. Instead, they were developed by two of Louis' twelve disciples, named Harlan and Fedin, who studied theoretical mathematics.  At the beginning, among the twelve original disciples of Lewis, there were two mathematicians. Although they both studied theoretical mathematics, their tendencies were slightly different.  One of them, Fedin, mainly studies cutting-edge science such as quantum mathematics, and the other person, Harlan, mainly studies computational mathematics, a subject between applied mathematics and theoretical mathematics.  Of course, there is a lot of overlap in the research and development of the two, so their laboratories are actually connected.  As long as a group of people are together, there will inevitably be fights. Take the Blue Illuminati as an example. Although it is not stated explicitly, the people inside are basically divided into three major factions with their vice president as the core.  , respectively, are the Lewis Faction, the Martina Faction and the Vivian Faction, and even within a faction, different people will compete.  For example, although people like Alfonso, Harlan, and Fedin are from the same lineage and are the original Twelve Apostles, and have all eaten Green Flash, they are still very competitive with each other, or in other words,  These twelve people are each other.  Different small circles were formed.  No matter what you do, it is always better to have more people, even if you are engaged in research and development, it is the same.  Therefore, whether it was due to the competitiveness of the young people or indeed for their own research projects, the twelve disciples of Lewis were constantly working hard to produce results in exchange for membership of the new disciples.  Because there were regulations within the organization at the time, the qualifications to recommend new members must be those who have produced valuable results.  Whoever comes up with results recognized by the organization first will get more blue flashes, or memberships.  Obviously, whoever has the right to recommend, then after the recommended person enters the organization, he will basically become a member of his own line. This is an obvious way to strengthen himself, and when Cheng Yuan tried hard to give Louis a  After adding new disciple candidates, it has become a consensus.     To know.  So far, Louis' men have the largest number of disciples, which has already aroused the jealousy of Martina and Vivian's men.     anyway.  Why was Alfonso able to produce results so quickly?  It is because there are enough new disciples studying materials science assigned to them, and then they will lead some ordinary scientific researchers and use super-technological equipment, so it is normal for the progress to be accelerated.  Although Alfonso and others already have many disciples.  Alfonso and the twelve people who had eaten the green flash in the early days have all become de facto small bosses, but no one thinks there are too many people.  So this time I heard that Cheng Yuan was actually concerned about other colleagues' projects, so naturally I felt a little uncomfortable.  However, they were from the same faction after all, so Alfonso's discomfort was fleeting, and he quickly took Cheng Yuan to the laboratory on the other side, where Harlan and Fedin's joint laboratory was also  Where nanochips and 5g mobile communication technology come out.  Regarding the arrival of Cheng Yuan, Feidin and Harlan were a little cold, not as enthusiastic as Alfonso, but this was probably related to their personalities and not deliberately pretentious.  Although they behave indifferently, they are still very excited when talking about technology. After all, for people like them who have become scientific research madmen, technology is like their biological children, so they naturally want to show off to others when they have time.  one time.  ???First, let¡¯s talk about nanochips.  To put it simply, nanochips use nanotechnology to directly combine designed molecules in the laboratory to form chips. In this way, there is no need for an ultra-clean production workshop like traditional silicon-based chips.  There is no need for expensive production equipment and a large production team, which can greatly save costs.  Moreover, nanochips are smaller in size, faster in computing, and consume less energy. A nanochip composed of carbon nanotransistors is not only much smaller than a silicon chip, but is also more than 15,000 times faster than a silicon chip, but consumes a lot of energy.  Reduce, it can be said to be a very cost-effective chip.  In fact, the technology of nanochips is not new. The technology of nanochips has been around for a long time, and the system is relatively mature. The main thing that restricts the development of this technology is the acquisition of materials.??It's just how easy it is to obtain carbon nanotransistors.  After carbon nanotransistors could be produced in large quantities, this technology broke through the bottleneck. With the joint research of Feidin and Harlan, they quickly broke through a series of other small problems and began to mature this technology.  change.  When nanochips mature, nanocomputers can be developed. In fact, so far, new nanostorage technologies, carbon nanocircuit boards and other technologies have been developed. Nanocomputers have also been born in research laboratories, and even industrial production methods have been developed.  We have also researched it and are just waiting for further improvement before launching the production line directly.  "Is this that kind of nanochip?" Cheng Yuan asked, looking at the small square in his palm that was only the size of a seven-star ladybug.  "To be precise, this is a nanocomputer." Feidin explained on the side. "A real nanochip is much smaller than this. It is only as thin as a hair and smaller than a grain of sand. This thing in your hand  , is a complete computer, which not only includes a microprocessor, but also a motherboard and storage, and can be operated independently. " "Oh? Can you demonstrate it?" Cheng Yuan asked with interest.  "Of course." Feiding nodded, picked up the seven-star ladybug in Cheng Yuan's palm with tweezers, and then carefully placed it in a small square box only the size of a fist, and explained at the same time, "Because this kind of nanocomputer is too  It is small, so it is necessary to design the power supply system and the internal and external transmission system separately. This small square box is a combination of the power supply system and the internal and external transmission system. " After finishing speaking, Feiding closed the glass cover of the small square box, and then  He took the monitor, keyboard, stereo and other items, plugged a series of data cables into the sockets of the small square box, and then said to Cheng Yuan: "It's ready now. Do you want to turn it on and try it yourself?" "Oh, then  Of course." Cheng Yuan smiled and pointed to an oval button in the small square box.  "Is this the power-on button?" "Yes." Feidin nodded.  After receiving the reply, Cheng Yuan stopped talking nonsense and directly pressed the power button. Soon, the monitor lit up and a familiar operating system screen began to appear.  Seeing this situation, Feiding smiled and said: "Because the speed is too fast, the operating system screen will be launched directly when you turn on the computer, so you no longer have to wait for the boot screen." "This is not bad. I usually hate it the most.  Waiting for the startup screen." Cheng Yuan smiled. After laughing, he operated again and found that the computer responded very quickly.  No sluggishness at all.  Nodding with satisfaction, Cheng Yuan asked Feiding again: "What are the parameters and performance of this computer?" "The processor of this computer is a 164-core processor, and the clock frequency of each core can be as high as 36ghz.  Frequency, as for the memory, the memory is 256t and the external memory is 756t, which is completely comparable to a supercomputer." Feiding paused here.  Then he continued, "After our calculations, this computer can perform 4 quadrillion operations per second. The peak speed of double-precision floating point operations can reach 459 quadrillion operations per second. If it continues to operate, the double-precision floating point operation can reach 4.59 quadrillion operations per second.  The peak operation can reach 239 billion times. Of course, the most important thing is that this one can be said to be completely comparable to a supercomputer, and the power consumption is only the amount of an AA battery! " "Really? "  Cheng Yuan exclaimed, "I know that nanocomputers are very good, and foreign countries have already developed finished products, but they are not so powerful, right?" "Haha, the key is still a matter of materials and technology." Alfonso next to him suddenly rushed to grab it  Said, "Actually, the key to this kind of computer is to look at the material technology. If there are good carbon nanotransistors and better chip design, there will naturally be a big leap forward." Glancing at Alfonso, next to him  Feidin nodded: "Yes, the key is still the issue of materials and technology. Of course, architectural design and other aspects are also very important. In fact, the reason why this computer has such strong capabilities is mainly because of all its design  They all use carbon nanotransistor materials, and this carbon nanotransistor is not an ordinary carbon nanotube, but is made directly from graphene material. It is a perfect carbon nanotransistor. In addition, not only all.  The core chip is made of carbon nanotransistors. Other motherboard materials are also carbon nanotransistors made of graphene. The same is true for the memory. The entire computer is made of a two-dimensional graphene, which is then folded like origami.  Different shapes form different circuit modules. Because the graphene structure has super strong electron conductivity and is the fastest material to transfer electrons at room temperature, it consumes very little energy. This leads to this.  This is because the computer is very powerful and consumes very little power." "Yes, that's right." Cheng Yuan nodded."In this way, the miniaturization of supercomputers can be achieved, and the effect will be revolutionary." "It's more than that." At this time, Harlan, who didn't speak much next to him, suddenly said, "We are interested in supercomputers."  The discovery of this material is still very shallow, and we are also using traditional chip models. In fact, due to the unique quantum field force of graphene material, the structural properties have undergone fundamental changes, so quantum computing can be achieved, that is to say,  As long as we do more research and change the computing mode, we can realize a miniaturized quantum computer. By then, the computing speed will be a qualitative improvement! " "Quantum computer, you mean, a quantum computer based on nanometer technology?" Cheng Yuan asked.  .  "Yes." Harlan nodded. "This kind of computer is actually just our experimental work. It's nothing. What Fedin and I are working on is actually the miniaturization of quantum computers. As long as we are given a little more time,  With resources, I believe that the trial production will be successful soon. By then, the whole world will be different!" "Yes." Feidin sighed and nodded, "Just imagine, in the near future, you can  The watch you wear is a computing device that is faster than today's supercomputers. In this way, we humans will truly enter the era of computing. At that time, everything will become simpler and faster, and so will intelligent robots.  Becoming smarter, virtual reality networks will become a reality. Isn't that a wonderful era? " "Indeed, the prospects are bright." Cheng Yuan nodded, "Let's not talk about quantum computers for now. Let's talk about this computer.  The performance of a computer is already very strong. I would like to ask how much does this computer cost? " "The cost," Feidin thought for a while, "because it is a test product and has not been industrialized, so it will be higher.  Including the cost of materials and production, such a computer costs about 100,000 euros. ""One hundred thousand euros considering this kind of performance, it is very cheap." Cheng Yuan nodded.  "So, what if this kind of computer is simplified? For example, it doesn't need such high performance, it doesn't need 164 cores, and it doesn't need such high storage capacity. If it only has 6 cores and about 10t of storage, how much cheaper will it be?"  "I'm afraid it's not much cheaper." Feiding shook his head, "Because this is mainly the price of materials. In terms of production technology, because it uses a new type of intelligent tunnel scanning technology, manual operation is no longer required. So on the same chip  , there is not much difference between making 6 cores and making 164 cores. On the contrary, making 6 core circuits will cause a lot of waste, and the same goes for storage materials. In other words, the current computer was made by us.  The most cost-effective one, even if the process is simplified, the price will not be less than 90,000 euros, but the performance is too poor, so it is not cost-effective." "I understand," Cheng Yuandao, "In the final analysis, it is because of the production process.  Different, so the production method has changed, and the price can no longer be calculated purely based on the performance of the computer." "That's right," Feidin nodded.  "So, how much would it cost to set up a factory to produce this kind of computer? How much space is needed?" Cheng Yuan asked again.  "I'm afraid this doesn't require much space. Just a 100-square-meter room can be used to build a nanocomputer factory." Feiding said, "As for the investment, I haven't calculated it specifically, but based on the materials required for the production line we designed,  Calculated, at the current market price, about 150 million euros is enough. After completion, it can theoretically produce 220 such computers per day, and in fact, it can produce more than 200 computers. The output is still considerable.  "More than 200 units? You mean the complete computer?" "Of course." Feidin nodded, "Because this is a direct synthesis of circuits using nanotechnology, there is no need for a complicated assembly process.  Partially synthesize a highly integrated computer. Of course, it is not impossible to assemble it into individual components, but that would consume more resources and be uneconomical. " "In other words, this kind of computer is integrated.  "You can't use the parts separately?" "That's right." Feidin admitted, "So in other words, if it breaks, the whole machine needs to be refurbished and replaced with a new one." "What about the data?  If it breaks, what should I do with the stored data? " "Basically, the part that stores the data will not break easily. The main thing that is easy to break is the processor," Feiding said, "So if the computer breaks, you can just put it inside.  The stored content is read out and saved. Even if the storage device is broken, the undamaged part of the data can be read out. Of course, there will be a certain loss. However, in real computers, if the storage device is broken, the data  Same thing. In comparison, our nanocomputers are made ofIt's extremely small, and it's made of carbon nanotransistors. Its strength is several times higher than steel, and it won't break easily. Even if you step hard on that ladybug-sized computer, drop it hard, or even hit it with a hammer.  , generally not bad.  "    "Not bad.  Cheng Yuan looked at Fannia who started playing Need for Speed ??on the computer, and nodded, "It seems you have developed something amazing."  By the way, didn¡¯t you also develop some 5G communication system?  Can you tell me about it and take a look?  " "Oh, you are talking about terahertz mobile communication technology.  Feiding said, "Indeed, we have also achieved a breakthrough in this technology. Well, how about I demonstrate it to you here."  " After speaking, Feiding took out a black 5.0-inch mobile phone and said: "This mobile phone is specially made. The unique thing is that it is embedded with a new nanocomputer that we just demonstrated.  However, since the mobile phone motherboard is still a normal circuit board design, it cannot fully utilize the performance of the nanocomputer embedded in it. However, even so, 5g communication can be directly achieved through this mobile phone. Here, we only use the processing of the nanocomputer  It's just a function, after all, it's the fastest way.  " "Well, then you can demonstrate it.  "Cheng Yuandao. "Okay.  Feiding nodded, and then started to operate. Then he opened a piece of software and showed it to Cheng Yuan, "Look, this is a test software that can perform wireless downloads and uploads. Through this, you can get the wireless download speed of your mobile phone."  With the transmission speed, this base has already covered the 5g mobile communication network, which is not a wifi and other modes, but a real long-distance mobile communication technology!  " Finished speaking. Feiding clicked one of the buttons, and then he saw a clock-like thing constantly changing numbers. Then Feiding pointed at the clock and said: "Look, this is to test the download speed.  We just downloaded a large video file, which is 180g. Now we can see that the download speed is 10gb per second.  You see, as we speak, the 180g video has been downloaded.  The whole thing takes only 19 seconds!  ¡± Having said this, Feiding showed the phone screen to Cheng Yuan. Sure enough, Cheng Yuan found that in the following records, the recorded average download speed reached 9.92gb per second, and the highest peak download speed was 10.65gb per second, downloading a 180g  The video only lasted 19 seconds! ¡°South Korea made a statement some time ago, saying that they have developed a 5G system, haha, but that thing is just a toy compared to ours.  Feidin smiled, "With Korean technology, the download speed cannot even reach 1g per second, and the transmission distance is limited. It is said to be two kilometers, but in fact it is only about one kilometer."  What we use is terahertz technology, which has higher frequency, farther transmission speed, wider coverage, and can directly realize point-to-point transmission between the ground and satellites.  " "Terahertz technology?  Already mature for research?  "Cheng Yuan asked. "Of course.  Feidin nodded, "Actually, Ericsson has been exploring terahertz technology before, mainly researching terahertz communication technology. However, you also know that the main difficulty of terahertz technology is economical and portable transmitters and receivers."  , the application is actually easy, and after our material technology breakthrough, they applied nanotechnology and easily achieved technological breakthroughs in terahertz.  Coupled with the application of our micro nanocomputers and the application of terahertz technology, 5g communication is completely mature.  " After a pause, Fedin continued: "Due to the superiority of terahertz technology, in our vision, the future 5g communication technology will be a brand-new model, that is, it can be launched through satellites and  Create a model of high-altitude airship base stations to achieve global coverage and no blind spots around the world.  Of course, it can also be combined with existing base stations to accommodate existing 2G and 3G communication technologies.  " "Launching satellites, high-altitude airship base stations?  Will there be any cost issues? Also, have you thought about the maintenance issues in the future?  " "We have thought about all this.  "Fedding said, "Due to the variability of this technology, the traditional base station model has become uneconomical.  For example, the traditional base station model requires building a base station at a certain distance and connecting it into a network. It also requires corresponding personnel to perform regular maintenance. It is indeed convenient under the existing technology, but under terahertz and microwave technology, these technologies are outdated.  .  You see, our terahertz transmission technology has longer transmission distance, more data transmission volume, and stronger penetrability. Even 50 meters underground, signals can be received, and the data download speed can still reach 8g per hour.  Seconds, the upload speed can also reach 6g per second.  And because it can accommodate a larger amount of data, a high-altitude airship base station can accommodate 300 million information objects, which means it can accommodate 300 million people calling each other to download data without problems.  Basically, for the six billion people in the world, we only need to build twenty high-altitude airship base stations, or??Twenty satellites can perfectly solve all communication problems.  Compared with the construction of ground base stations, the cost advantage is much stronger.  Moreover, because we have nanocomputer technology, each satellite can accommodate multiple supercomputers, allowing the satellite to become smaller and have stronger data processing capabilities. Therefore, the satellite can be miniaturized and the launch cost will be lower.  Low.  We have calculated that if 20 satellites are launched, and each satellite can accommodate 300 million information objects, then one satellite only needs to be as big as a mobile phone. In this way, one rocket can be launched at once and carry 20 satellites.  , using multi-body separation technology, it is possible to achieve full coverage with one rocket.  Of course, in practice, it is impossible to launch only 20 satellites and double as backup, but the cost will not be very high.  As for maintenance, let alone high-altitude airships, they are very convenient. Even for satellites, new satellites can be directly launched to replace broken satellites. Broken satellites can be recovered by spacecraft. Due to the small size of satellites, recovery will become very complicated.  convenient.  "    "not only that.  Harlan said on the side, "In fact, launching satellites can not only be used for this new transmission system. Since they can carry our newly developed nanocomputers, each satellite is a supercomputer, so it can also be used in other aspects."  parallel operations.  For example, this satellite can carry out navigation, geological research, meteorological research, etc. It is equivalent to a satellite with multiple functions. It can be said that it combines the functions of meteorological satellites, military navigation satellites, communication satellites, etc., and the price/performance ratio will be better.  Becoming more superior.  "    "Yes.  "Feiding continued, "At that time, the entire earth will be transparent to us, and if the satellites are equipped with high-energy laser weapons, haha, then the missiles will completely enter the end of the era!  It can be said that as long as we launch enough satellites, the whole world will be in the palm of our hands!  " "Yes, a very good idea.  Cheng Yuan nodded calmly, "How much will it cost to complete the construction of this system?"  " "This has not been carefully calculated.  Feidin shook his head, "However, if there are two to three billion US dollars, it should be enough."  " "Twenty to three billion US dollars" Cheng Yuan nodded, "In terms of building a new system, this cost is not high.  "    "I think so.  "Feiding also nodded. "Very good.  Cheng Yuan said with satisfaction, "You have done a good job. I will report your matters truthfully. Well, do you have any requirements?"  " "Well, if possible, can you increase the number of new members for us?  Feidin said, "Actually, Harlan and I still have many friends and relatives. If possible, can we bring them in?"  " "Friends and relatives?  Cheng Yuan frowned, "You should know that the organization's affairs cannot be told to the outside world easily. You" "Don't worry, I didn't tell them about the organization's affairs."  Feidin said quickly, "They just know that I work here."  However, they are really reliable, and we do lack manpower. If there are enough members to help, our research speed can definitely be faster.  " "That's it.  Cheng Yuan thought for a while, "You can give me a list later. After we investigate and there are no problems, we can authorize you."  Well, in view of your performance, I will give you and Harlan 20 quotas each. What do you think?  "    "Very good!  Feidin snapped his fingers, "That's enough, haha, I'll just say, our organization is the future of mankind, and we will eventually make history!"  "(To be continued, please search Piaotian Literature, the novels will be better and updated faster!
