North America, Washington.
In a spacious conference room, the important figures of the country gathered, they came from the White House, the Department of Defense, the Central Intelligence Agency, as well as the heads of NASA and major laboratories.
Musk is also in the ranks of these people, and is in a more important position. He seems to be a little bored playing with the ballpoint pen in his hand. With a light flick of his thumb, the black ballpoint pen spins quickly in his palm up.
“Musk, what do you think about the space elevator?” The old man in a general uniform asked curiously. He seemed to be representing the Ministry of Defense to attend the meeting.
Musk frowned, then stood up, walked to the front of the meeting room, where the big screen was located, pointed to the No. 0 space station in the picture and said: “My view is very simple, those Chinese people, they have succeeded, So far, Star Technology’s space elevator plan has overcome all resistance and is moving forward steadily.”
“Someone mentioned the issue of pulling force just now, and thought that each nanotube weighs 360 tons, completely exceeding the pulling force of station zero. As the construction progresses, more and more nanotubes will eventually put the The space station was pulled into the atmosphere from the synchronous orbit, resulting in a crash.” New 81 Chinese website updates the fastest computer terminal: https://
“I disagree with this speculation. The weight of the elevator is indeed heavy, but Station Zero is like the counterweight of the space elevator. It is constantly being built and expanded, providing stronger and stronger pulling force. “
唰唰唰唰~
Musker brought over a whiteboard and began to write quickly, bringing the self-weight of station zero, the speed of the earth’s rotation, the length and weight of nanotubes, and a series of parameters into the formula, and finally got 1.6679 such a number. New 81 Chinese website updates the fastest mobile terminal: https:/
“Look, the pulling force provided by station zero is always kept at 1.6 times the self-weight of the nanotube line. Star Technology has left enough safety redundancy. In my opinion, they are not radical, even very conservative. Always put safety first in the space elevator.”
Mathematics does not lie. Musk’s calculations undoubtedly confirmed the safety of the space elevator. At the same time, this well-known North American genius also showed his strong mathematical skills. He calculated the space in his head without using tools. Elevator tension redundancy.
There was a sigh in the conference room, and everyone was speechless for a long time. Up to now, they still can’t believe that a miracle-making space elevator is on top of their heads, and the Chinese people who built the elevator are just a few dozen Years ago, they were too poor to eat enough.
However, in a blink of an eye, Diaosi counterattacked, and the Chinese actually crushed the invincible North American and Western civilizations in the space field with a destructive momentum, which is embarrassing.
President’s special envoy Mitterrand nodded slightly: “The White House does not want to delve into the fact that it has been established, but Mr. President wants to know that the elevator of Star Technology will be completed in February next year. What can we do to surpass those Chinese people? ?”
Overtake?
The conference room became even more silent now, and the elites from the scientific community secretly slandered that the president is indeed a layman who doesn’t understand farts. Not bad, as for geosynchronous orbit and outer space, North America simply has no strength to compete.
Seeing that everyone was silent, a sense of sadness welled up in Mitterrand’s heart. Back then, NASA was the only one in the world, and Armstrong successfully landed on the moon, which shocked the world and attracted worldwide attention. What kind of scenery and courage was that .
In a blink of an eye, the smoke cleared, and upon receiving the news that the space elevator was about to be built, many countries, including some allies in North America, lined up to visit China, hoping to get a share of the future space development.
Compared to the small earth, a fool also knows that the future of mankind can only lie in the distant sea of stars, and China is the only existence that can provide tickets for the sea of stars.
“We still have a chance in the field of controllable fusion.” Dr. Shulakel said in a deep voice: “At present, we have many laboratories that are investing in the research of controllable fusion at any cost. Once we succeed, Whether Star Technology’s Karman vortex street power generation technology, or their space elevator, will be overtaken by our Jedi.”
Everyone nodded slightly. North America has indeed invested a lot in controllable fusion research. The famous Ross Laboratory, Oak Ridge Laboratory, Argonne Laboratory, etc., all have fusion research teams.
Musk smiled and said: “Nuclear fusion is indeed an opportunity. Although Star Technology’s Karman vortex street power generation array is strong, it cannot be applied outside the earth. Spaceships equipped with fusion reactors and super ion thrusters, theoretically It can take off and land vertically between the earth and space, so the significance of Huaxia having a space elevator is also offset.”
“The liquid oxygen methane engine currently used by space vehicles is very heavy and consumes a huge amount of energy. If we want to develop Mars without fusion technology, we must build a permanent space station in the outer orbit of Mars. Then use the Mars spacecraft to perform landing and disengagement operations. Sixty percent of the mass of the spacecraft must be used to load fuel. For example, if it weighs ten tons, six tons of it will be used to load fuel. Otherwise, it will not be possible to return to Mars. Here we come.”
“Of course, we can also have the luxury of making the Mars spacecraft into two stages. The landing stage sends the spacecraft to the surface of Mars and then it is discarded. When it comes back, we only drive to upgrade. Due to the weight reduction, we can carry more One ton or half a ton of supplies.”
“At the same time, we also need to build a large number of transport spacecraft to travel between the Earth space station and the Mars space station. Even if the best window period occurs every two years, the distance between Mars and the earth is as long as 7,000 Eight million kilometers and a standard flight time of 609 days, considering that we cannot always send a spacecraft during the window period, the average round-trip time to Mars will take four to five years.”
“We must build at least a dozen transport spacecraft, because people who stay on Mars will consume supplies every moment, and the distance from Earth to Mars is so long, assuming we don’t have enough transport power , the construction team stationed in the Martian area will run out of ammunition and food, after all, unlike Xingchen Technology, we don’t have robotic technology, and we need to send a large number of human engineers to develop Mars.”
“But if there is controllable fusion, the situation is completely different. A super-large spacecraft equipped with controllable fusion can weigh thousands of tons or even tens of thousands of tons, and has decades of self-sustainability. Not to mention Mars, crossing the Ebola belt and flying out of the solar system is definitely not impossible.”
“So everyone, do you understand? A spaceship equipped with controlled fusion will be as powerful as the Star Destroyer we have seen in Star Wars, and a small wreck that uses liquid oxygen methane fuel is not a species at all! “
Musk talked eloquently that colonizing Mars is his lifelong dream. Various designs and concepts have already been very mature. The long starry sky and countless risks and difficulties are presented to everyone through Musk’s description, which makes people sigh.
After a pause, Musk continued: “According to intelligence, Xingchen Technology has started a fusion experiment in southwest China. Fortunately, they, like the group of dead-brained Germans, chose the stellarator It is expected that there will be huge resistance to the plan.”
Hahaha~
There was a knowing smile on everyone’s face. If the stellarator can be successful, it would be hell. Except for the stubborn Germans, no one has played this thing for a long time.
Mr. Mitterrand let out a cold snort, and said in a deep voice: “It is rare for Star Technology to make a strategic misjudgment. Since they want to die by themselves, we should seize the opportunity and give them a funeral.”
In the end, these big figures in the North American authorities unanimously decided to increase investment in controllable fusion research, and invest more funds in this field, as well as in all other fields that may compete with Star Technology.
As we all know, the finances of North America have long been unable to make ends meet, and the deficit generated by increasing investment will be raised through the issuance of national debt.
…
Chengdu, Southwest Branch of Xingchen Science and Technology Fusion Research Institute.
On the eve of the fusion experiment, many people came than expected. In addition to the leaders of the two institutes, the military also sent a representative team, and the general’s most trusted secretary, Lu Junlin, was also among them.
“The general has a special status and it is inconvenient to appear here, but he told me to tell you, do it boldly and don’t have any worries. The army will always be your solid backing.” Lu Junlin said to Luo Jia.
Luo Jia has heard this kind of words for countless times. Anyone with a discerning eye can see that the relationship between Xingchen Technology and the military is absolutely extraordinary. This probably belongs to the sympathy between tough guys. Throw your temper, how you look at how pleasing to the eye.
The two walked into a classroom-like room hand in hand. Due to the large number of people, there was no room to sit in the conference room, so the administration department arranged another large room for Luo Jia, and Luo Jia wanted to represent Xingchen Technology to respond to the big bosses from all parties. The problem.
“Mr. Luo, when will the fusion experiment start?” an old man wearing glasses asked.
Luo Jia raised his wrist and glanced at the smart watch, “Specifically speaking, there are still three hours and forty-five minutes, which is one o’clock in the morning tonight, and we will carry out the double-helix stellarator fusion device on time. The first ignition, currently, my colleague, Dr. Xie Tian, is conducting the final inspection and preparation.”
“I heard that you not only abandoned the traditional tokamak and chose a stellarator for the fusion device this time, but you are also different in terms of fusion matter, choosing the deuterium-deuterium reaction?” the bushy old man asked.
After hearing these words, there was an uproar. Most of the people present were experts. react.
“Reaction with deuterium and deuterium? So awesome!?”
“Am I not mistaken, Xingchen Technology has mastered deuterium-deuterium reaction technology?”
“It’s a bit unbelievable, don’t worry, let me take a look…”
Seeing the surprised expressions of everyone in the audience, Luo Jia hurriedly explained with a smile: “Senior, your source of information may be misunderstood. First of all, I am really optimistic about deuterium-deuterium fusion, because deuterium-deuterium fusion is really very cheap. “
“Deuterium is an isotope of hydrogen. The content of deuterium in seawater is very high. On average, there is one deuterium atom for every 6420 hydrogen atoms. The total tonnage of seawater on the earth is about 1.4 times 10 to the 18th power, which is Forty trillion tons of deuterium elements, without considering the energy conversion efficiency, so much deuterium can theoretically generate 9 times 10 to the 24th power of electricity, enough to use the entire earth for 90 billion years.”
“According to the current market price, the price of deuterium monoxide per kilogram is 7,000 yuan. After fusion, it can generate 80 million kWh of electricity, and the cost is almost negligible. What’s more, traditional space probes often have to carry several Tons of liquid oxygen methane are used as propellant, and with controllable fusion, we can travel back and forth in the solar system with just a kilogram, and with a few tons of fuel, we dare to rush out of the solar system. Break into the galaxy!”
After listening to Luo Jia’s words, everyone nodded their heads. The reason why there were nearly 20 bigwigs from the two institutes at the scene was because of the emphasis on controllable fusion. If the experiment is successful tonight, the scientists will almost Wake up with a smile, controllable fusion is one of the most critical keys to the road to the sea of stars, it is really against the sky.
“That is to say, deuterium-deuterium fusion is the future goal of Xingchen Technology, not the current goal?” An academician understood Luo Jia’s words and tried to ask.
Luo Jia said: “That’s it~Soverse.com~ In the experiment early this morning, the reactants we used were traditional deuterium and tritium, but tritium is really too expensive, because the half-life of tritium is only ten years, so Tritium almost does not exist in nature, and it is extremely difficult to artificially prepare it. The price per kilogram exceeds 150 million U.S. dollars, and we cannot afford it, so we added a multiplication system to the reaction.”
“To put it simply, the breeding system is to use the neutrons produced by fusion to react with lithium to generate and multiply tritium, which means to consume and reproduce at the same time, but the efficiency of using neutrons to generate tritium is not high, so We developed a second system, the recycling system.”
“First, we reduce the retention of tritium outside the recycling loop, and maintain the total amount of tritium. Then, we use the plasma material that directly wraps deuterium and tritium in fusion, mainly tungsten, to create a tritium capture and recovery system.”
“Anyway, our double-helix stellarator fusion device only needs to consume extremely small amounts of tritium as fuel, and adding deuterium and lithium continuously during the reaction process is enough to maintain its normal operation, because we have multiplication The tritium is protected by two auxiliary systems, the cyclic capture system and the circulation capture system, which are our original creations.”
Luo Jia talked about his design ideas. Energy Civilization is indeed the top player in star fusion technology. Just look at the expressions of the experts present to see how advanced the double helix stellarator fusion device is.
At this moment, the room was silent. After hearing about the fusion device of Xingchen Technology and two sets of auxiliary systems that had never been heard before, the bigwigs from the two houses felt as if they were listening to a book from heaven, and they were all stupid .
