0152 The tech tree is getting more and more bizarre

On D35, Xia Ming began to discuss the second phase of energy issues with Xiaotang.

The first stage of the "fuze" probe will arrive at Zhishen on D132, this total weight of only 500 kilograms of the detector, nearly 90% of the weight is consumed in the engine and power supply, the detection equipment only has cameras and LED searchlights, the communication system is all based on Qianyan MINI, the risk is very high, in fact, it is to try your luck first.

The real hope lies in the second phase of the "detonator" detector, if the 10 megawatt VASIMR can be successfully developed, the total weight of the "detonator" can reach 4 tons, and then the detection and communication equipment will have a larger margin.

The Detonator is planned to reach Homo sapiens on D160, and it is designed to be faster than the Fuze, which is expected to take only 50 days. That is to say, on D90, 23 days after the departure of the "fuse", the "detonator" will follow the sky.

However, the bottleneck of the "detonator" is still in energy, and solar cells cannot meet the appetite of 10 MW VASIR, so they can only be used as auxiliary energy.

Xia Ming has devoted himself to various cutting-edge energy technologies during this time, and now he has finally come up with the energy system design of the "detonator" detector.

However, when Xiaotang heard this term, he was suspicious.

"Flywheel batteries?"

"Yes, flywheel battery!"

Xia Ming explained: "The energy system that Qianyan and I conceived is like this, with solar cells, supercapacitors and flywheel batteries forming a joint system, with flywheel batteries as the core, complementing each other. As long as the total weight of the detector is maintained within 4 tons, the energy of this solution is sufficient. ”

Xiaotang was silent for a while, probably using PEI to find information to confirm this technology, and then she frowned and said: "This flywheel battery still needs to be improved a lot." ”

Xia Ming nodded: "It's indeed a huge challenge, but compared to other technologies that require new principles or new discoveries, flywheel batteries still have a lot of potential." The technical difficulty lies in the material. ”

Xiaotang pinched his chin and squinted his eyes: "Interesting, gallium nitride is almost done, I'll solve it." ”

Flywheel batteries, or FESS for short, are indeed an interesting energy storage technology.

Unlike nuclear batteries and chemical batteries, flywheel batteries are mechanical energy storage, and its technical idea is very simple.

As we all know, power stations rely on rotors to cut magnetic field lines to generate electricity, and the mechanical energy of the rotors becomes electricity. Hydropower plants rely on the flow of water to propel the rotor. Thermal power plants rely on the heat energy of medium and oil or natural gas to propel the rotor, while nuclear power plants rely on the heat energy of nuclear fission and boiling water to propel the rotor.

The flywheel battery uses the flywheel as a rotor, and when it is charged, the rotor rotates rapidly to convert electrical energy into mechanical energy. When discharging, the rotor converts mechanical energy into electrical energy. The DC motor is reversible, can generate and discharge electricity, the principle is simple, and the structure is simple.

But. The seemingly simple technique has many thresholds, the first is frictional resistance, and the second is the material, and the flywheel must reach at least tens of thousands of revolutions per minute. Ordinary materials are not bearable.

This concept was put forward in the seventies of the last century, and because of these two difficulties, it took more than 40 years to become a reality in the previous years.

Flywheel batteries are now well established. UPS is the most widely used in the field. In other areas, such as electric vehicles, there have also been applications for a long time. Load the flywheel battery into the wheels of your car. Absorb the energy of wheel braking, which is already standard in many luxury cars. Porsche's F1 cars also use flywheel batteries as auxiliary power, and NASA also has flywheel batteries on the space station.

The most eye-catching application is still aircraft carriers, Ford's electromagnetic catapult system has flywheel battery components, Huaxia's electromagnetic catapult system also takes this route, because its power density is higher than that of supercapacitors, in the saying that it is explosive.

But even now, flywheel batteries still have great defects, and the main problem is frictional loss.

Nowadays, flywheel batteries, which are widely used, are operated by vacuum. Even so, the rate of natural attrition is more than 10% per day. Once discharged, the losses will be more severe.

However, superconducting technology has significantly improved the flywheel battery, using the superconducting principle to stabilize the flywheel, removing the bearing with direct contact, and reducing the friction loss a lot. The flywheel battery based on superconducting magnetic levitation has a natural attrition rate of less than 2% per day.

Another difficulty is the flywheel itself, in order to store higher energy, the flywheel must rotate faster and be lighter, not only to reduce friction (vacuum is not absolute), but also to allow the entire battery to adapt to motion with a higher margin.

In motion, it is difficult for the flywheel to remain stable. In a superconducting environment, the superconducting electric field generated by the superconducting magnetic levitation will stabilize the flywheel's state and prevent it from moving. If the flywheel is light enough, it is very stable.

It's just that superconducting technology has not yet stepped into the field of room temperature, and a set of cooling equipment is needed, and the volume and energy consumption of cooling equipment are not small, so superconducting flywheel batteries have not been able to enter daily applications.

However, for astronautics, these two problems are not prominent.

Whether it is materials or superconductivity, it happens to be Xiaotang's professional field. She roughly estimated that the speed of the flywheel would have to be increased by a factor of ten and the losses reduced by a factor of ten to meet the needs of the "detonator" detector, both of which fell on the material.

"Come on, Qianyan, go crazy", in the laboratory, Xiaotang muttered to Qianyan.

"Are you talking about a workload or a spontaneous mindset? In the case of the former, my average load has reached 27% in the last month, and the number of thought patterns I have been exposed to has increased to 72, which has allowed me to grow faster. But it's not up to me to make me more loaded, it's up to you. ”

"If it's the latter, I'm sorry I can't do it, humans rely on intuition to do sparkling thinking, and I can only rely on random numbers, which makes no sense."

Qianyan's serious correction made Xiaotang smile bitterly and shook his head, after all, it was just a simulated mental model.

"To be light, to be strong, is this intentional?"

When Xia Ming said about the take-off wheel battery, Xiaotang thought of an answer, but she couldn't believe it, it would be so coincidental?

"Qianyan, unseal the technical information on graphene."

The discovery of gravity is smashed by an apple, the discovery of penicillin is careless, and the discovery of graphene is a boring act, although this is a fairy tale of bosom friends. The importance of luck in scientific research cannot be denied.

Xiaotang didn't bother to ask if there was anyone in the dark who was taking care of her, she only knew that the windfall from the previous stage had become the best choice at this stage.

That's right, what could be lighter and stronger than graphene materials?

Of course, she can't directly use a single layer of graphene to make a flywheel, it is too light, and the strength is definitely not enough. What's more, the flywheel material must be permanently magnetic. Graphene is not magnetic, she has to find magnetized graphene. Methods without compromising performance. Then use the nanotubes woven from graphene as fibers, and mix them with polymer carbon fibers to form a flywheel.

How do you magnetize it......

"Searching for relevant academic papers, graphene can be permanently magnetized by yttrium iron garnet, and yttrium iron garnet is an insulator, which will not affect the electronic properties of graphene."

Qianyan's prompt is like a fairy sound for Xiaotang to come to the club, this is the benefit of Qianyan, an omniscient research consultant.

She asked Qian Yan again whose paper it was. Qianyan said: "University of California, Professor Shi. ”

Xiaotang snapped his fingers: "I've heard him give him several classes, it's great!" ”

is still a senior in the same school, and this threshold has been crossed in a few thoughts......

When Xiaotang was buried in the laboratory. Xia Ming was pressed to the bed by Liluo.

Of course, it was not rolling the sheets, but Liluo's human neural model had preliminary results, and Xia Ming was asked to do the experiment.

The model was transmitted to Xia Ming's brain through QNI, and was deployed by Xia Xiaoyan. A panel appears in Xia Ming's AR field of vision.

Strong: ...... to be tested

Reaction: ...... to be tested

Sensitive: ...... to be detected

Constitution: to be tested......

Dexterity: To be analysed......

Endurance: To be analysed......

Status: To be analyzed......

This is a properties panel.

Xia Ming almost choked on saliva: "Hey! When did it change the system or game text? This style of painting is wrong! ”

"The first three are a trimeter assessment of your nervous system, the last three are a trimeter assessment of the nerve-related musculoskeletal conditions, and the last one is an assessment of your current state. As for what style of painting......"

Lilo spat back: "I, who don't play games, also know that the interactive interface of the game is the most user-friendly." Nowadays, whether it is industrial or military, human-computer interaction interfaces are moving closer to games, and those complex things are lost to intelligence to deal with. ”

"Didn't the remote control system you put on your power armor also be adapted from the game? What's wrong with digitizing information about your nerves and body and presenting it in an easy-to-understand way? ”

"Okay, Grandma of the Lord God", Liluo said so reasonably, Xia Ming was speechless.

Liluo tilted her head and thought about it, but she didn't understand what the main god and the old grandmother were together, so she threw it away: "Do you want to start testing?" As a reminder, you're going to have to suffer a bit in order to test your limits. ”

Looking at the patch electrodes all over his body, as well as the needles inserted into the muscles and blood vessels, Xia Ming sighed: "You have to be gentle." ”

"There's no one else but me, and no one will take care of you if you shout at a throat cut," Lillo laughed, "whatever you want to call it." ”

Uh, Xia Ming felt a little dangerous......

After Lillo's finger tapped in the air, the well-soundproofed ward was drowned out by waves of terrifying sounds. The nurses and doctors who occasionally passed by outside the door faintly heard the distant and mournful cry, as if a demon was howling in hell, and they all subconsciously shuddered, shrunk their heads and hurried away.

Ten minutes later, Xia Ming's face was as red as a drunken shrimp, the sweat was clearly rising, and the sheets under him were all wet.

"What is my name?"

"It's very penetrating, the rhythm is good, and the pain is just right."

"Thanks, please rate it."

"I'll give 9 points, 1 point less because I'm afraid you'll be proud."

"I mean this model of yours!"

The kung fu of arguing with Lilo, in the AR vision, the score also came out.

"Strong, 28 (Your nerves are thicker than an elephant, are you still human?) )”

"Response, 2.5 (Your nerves react 2.5 times faster than the average person!) In general, the stronger the nerves and the slower the reflexes, your existence is anti-science! )”

"Sensitive, 22 (Your nerves are sensitive enough to detect a mite crawling around your body, and if it weren't for consciousness, you'd be unlucky.) )”

"Physique, 0.7 (Your muscle strength, bone density, cardiorespiratory capacity, are only 70% of the standard adult male, you are either suffering from injuries or death. )”

"Dexterity, 0.6, (Whether it's the athletic envelope of your joints and muscles, or the tolerance of your ligaments and other soft tissues, it's only 60% of that of a standard adult male, and you're so clumsy that you can't even handle it as a junior high school student.) )”

"Endurance, 4.2, (Your body's patience for exhaustion and pain surpasses that of the saints!) )”

"Status, danger, (Your condition is obviously not normal, your body is too weak, your nerves are too strong, you are like a guy who has just crossed the house.) )”

Xia Ming closed this "attribute report" and asked Xia Xiaoyan first: "The text in the brackets is not that you are complaining, right?" ”

Xia Xiaoyan's two-dimensional little avatar shook cutely: "No, but if you like it, I will take the initiative to add it in the future." ”

"Veto!"

Xia Ming dismissed her attempt and asked Liluo again, "Have you been reading online novels recently?" I really thought there was a system cheat. ”

"I haven't read the kind of systematic text that has been outdated for many years", Liluo is equivalent to confessing, so Xia Ming has to sigh that the Chinese Internet culture is broad and profound, and it is already influencing foreign friends.

"The panel just gives you an intuitive understanding of your own body and nervous condition, and this model currently only involves the cerebellum and autonomic nerves, not the brain, after all, it is too complicated and sophisticated, and I don't dare to do it in that area."

"Now the model just has some templates for muscle and skeletal movements, and you can edit specific functions in the functional areas defined by these templates, and the next stage is to correlate the detection and management of all your organs."

Lilo explained the purpose of the model, which can be used for medical teaching and research, and can also be added to QNI for more precise control of the body. For Xia Ming, his QNI has become Xia Xiaoyan, and this model is Xia Xiaoyan is managing.

Xia Ming can set up various functions in this model, let Xia Xiaoyan manipulate his body, punch and dance, and it will be all at once. He can also manage his senses as needed, without having to use his brain to manipulate them directly.

"What are the specific features? Pain and touch management should be in place, right? Xia Ming asked, "Can you directly control your heartbeat?" ”

Lilo shook her head: "That's too dangerous, I didn't test it all the way from a guinea pig, so I didn't dare to try it easily." ”

She was curious: "Why do you want this feature?" ”

"If the springboard project needs the third stage, I have to go to Homo sapiens, and if something goes wrong and I can't come back, I can hibernate there and wait for you to come to my rescue."

Xia Ming seemed to be joking, Liluo smiled, smiled and smiled, but her expression became more and more solemn, and her eyes changed when she looked at Xia Ming.

"What's under the template? Functions and equations that haven't been formed yet? There's a lot to do. ”

Xia Ming muttered again: "Yo, this part is a little familiar......

"That's something I'm not sure about yet, don't move, some are related to autonomic nerves, like ......"

Before Liluo finished speaking, Xia Ming asked Xia Xiaoyan to perform one of the associations that he felt he knew, and then, his pupils suddenly constricted.

He shouted in his heart, "Stop! ”

Xia Xiaoyan stroked his forehead: "It's too late, muscles are not motors." ”

The water stains on the sheets spread out in a large circle, looking at Xia Ming's flushed face again, Liluo bit her lip, desperately held back a smile, and finished speaking: "For example, sphincter." ”

"Thank you for the late reminder", Xia Ming's face stiffened, what happened to Hou Yunting was repeated in himself, and the retribution was unpleasant.

A pair of hands grabbed his trouser belt, Xia Ming looked at Liluo in amazement, and blinked: "Don't get me wrong, it's ...... at this time."

She slapped her nose: "I'm not sexually interested, but it's not good for others to see you like this." ”

She asked tentatively: "If you are shy, just let Xiao Huan or Xiaotang come over?" ”

Xia Ming thought for a while and sighed: "It's your sin, I can only rely on you." ”

Lilo smiled coquettishly, but a hint of gloom flashed in her eyes. (To be continued.) )
