The world-famous Time Weekly has launched a special issue. On its cover, there is the ladder leading to space on Penglai Island!

    "So far, the greatest super project in human history has been born!" this is a comment written by the chief editor of time weekly.

    In the report, they described in detail the construction and test run of the space elevator.

    "It is undeniable that although it is the power to gather the world, Chinese enterprises and scientists have played the most important role in the design and manufacture of space elevator! This is a great creation in the history of human engineering!"

    "The road to space has been paved. It''s on Penglai Island in China!"

    "It''s really built!" countless people are celebrating and cheering internationally.

    "China is amazing. I always thought that the space elevator could not be built before. Unexpectedly, it was only two years!" netizens on the island said with emotion.

    "Such a great project is not ours." American netizens were shocked and felt some regret.

    "I want to see Penglai Island myself!"

    "What would it be like to take an elevator into space?"

    In Europe, people were surprised by the news, "the space elevator in the East has been built!"

    "They are so great. It is a feat beyond national boundaries!"

    "The first step of Du Xingyu''s plan has been realized. He will save us! Amen!"

    The video of space elevator transportation has exploded the world network, becoming the video with the highest playback volume and the highest praise comments in the world.

    It is difficult to count the data of various countries, but Du Xingyu knows that the energy points in his science and technology simulator soared by one billion points in one day!

    The successful operation of the heaven ladder finally let all mankind see a glimmer of hope for the Death Star crisis. Let negative people have confidence again.

    According to the survey of research institutions, one month after the news of TIANTI was broadcast, the suicide rate around the world decreased significantly, and the new number of patients with depression and doomsday phobia began to decrease.

    ……

    "The space elevator has been completed. Next, we will increase the number and frequency of lift cars, start to transport materials, build a near earth space port, and build bases on the moon and Mars," Du Xingyu said at the meeting of the human Guardian alliance.

    "The construction of spaceport, lunar base and Mars base will be led by China, and all parties can cooperate."

    Du Xingyu made clear the space construction plan in the era of crisis, just as the United States led the construction of the international space station.

    The current spaceport, lunar base and Mars base will also be built under the leadership of Huaxia, and other parties will pay and contribute to obtain a certain space.

    There is no doubt that they have absolute dominance in this.

    ……

    "If this goes on, they will become leaders in the space age!" after the meeting, several major forces on earth were dissatisfied.

    "Yes, now the space elevator has been built in China. The Tiangong space station and the near earth space port will follow the space elevator over them. The transportation hub of the space age is completely controlled by them."

    "They led the construction of lunar base and Mars base..." these strong men of the old era were worried.

    They have foreseen that in the foreseeable future, Oriental civilization will take the lead in entering the space age and walk ahead of everyone.

    "This is also a matter of no choice. The crisis of all mankind is coming. Without such cooperation, mankind will only have a dead end."

    Both Western Europe and North America are powerless about this. Within them, there are also a large number of capitalists and people who hope to cooperate with the East in exchange for the opportunity to survive the asteroid crisis in 20 years.

    "If you want to become a leader in the era of crisis, the only opportunity now is to master controllable nuclear fusion technology!" all parties mean that controllable nuclear fusion technology will be the only scientific and technological authority to "seal the gods" in the era of crisis!

    Up to now, the human Guardian alliance has failed to elect the top commander. The reason is that all parties are clearly aware that only the party who controls the controllable nuclear fusion technology is really qualified to lead all mankind through the crisis and survive!

    "Spare no effort to smash the controllable nuclear fusion technology. This is the moment to bet on fate!"

    All parties have begun their full research and development of controllable nuclear fusion.

    China is no exception. In order to develop controllable nuclear fusion technology, the Academy of Sciences has invested countless funds and resources in the Institute of atomic energy and the Institute of nuclear physics.

    Research and develop all materials needed; If there may be a promising model, make it; Learn foreign advanced technology... This is the real R & D of the whole country!

    Akimovich, a former Soviet physicist and the father of Tokamak, once said: "when the whole society needs it, fusion will be realized."

    Now is the time when all mankind needs nuclear fusion technology!

    But this is only the most ideal situation, although under the crisis, mankind erupted into crazy creativity. Every few months, technical problems will be overcome, but it seems that it is always decades away from mastering nuclear fusion technology!

    At the Institute of atomic energy, Du Xingyu and a group of nuclear physics experts are discussing the construction of a new Tokamak device.

    "Tritium supply and production problems; radioactivity problems; material problems; Tokamak rupture problems; instability control problems; plasma survival time; optical device damage; superconducting protection; first wall; repetition frequency... The difficulties in front of us can be said to be 100000 mountains! We study nuclear fusion against the sky!" Luo Yongzhen, a senior researcher at the Institute, frowned deeply. Even the top experts in this field feel a deep sense of powerlessness at the moment.

    No one knows when they will overcome one of the problems. And the most fatal thing is that sometimes studying a problem will produce four or five new problems.

    "The three key points of density, temperature and constraint time are the summary of all the problems we have encountered!" said Zhou Ziang, a gray haired academician of the Chinese Academy of Sciences, "I think the construction of a larger ring Tokamak device, at least ten times larger than the current Oriental super ring, can enhance the ability of magnetic restraint and temperature control, so as to have the opportunity to realize stronger nuclear fusion reaction."

    "Mr. Zhou, I don''t agree very much." everyone thought it was feasible, but Du Xingyu objected.

    "What do you think? Talk about it." Zhou Ziang looked at him.

    "In theory, the super large annular Tokamak device can indeed improve the fusion reaction, but it may only improve from thousands of seconds to tens of thousands of seconds, which is limited." Du Xingyu said. "Its construction needs too much time and money. We are racing against time, and we must master the nuclear fusion technology in the shortest time, otherwise everything will turn into dust when the death star comes!"

    "So I suggest that we can try to build a small Spherical Tokamak. Both the cost and construction time will be reduced."

    "What you said is also reasonable, but now we don''t have such materials at all. We can build a super magnetic field in a small container and accommodate nuclear fusion reactions." Zhou Ziang thought deeply.

    "To generate a super magnetic field with superconductors, the current superconducting materials need to be around 130K. While the temperature of high-temperature plasma is more than 100 million degrees, superconductors need to maintain more than minus 100 degrees Celsius, which is too contradictory unless we can find room temperature superconductors," said the researcher.

    "It''s not just room temperature superconductors. Even if the plasma is bound by the magnetic field, the high temperature generated will also produce a high temperature of thousands of degrees Celsius on the inner wall of the Tokamak device; moreover, neutrons generated by nuclear fusion cannot be 100% isolated, and high-energy neutrons will damage the superconducting coil..."

    "For large-scale Tokamak devices, we can also make the Q value of nuclear fusion reaction (energy output to input ratio) greater than one. When you talk about Spherical Tokamak devices, I''m worried that fusion will destroy the devices in one second," Zhou Ziang said.

    "What if I have a way to get room temperature superconductors?" Du Xingyu suddenly said.

    "What?" they were stunned, and then asked eagerly, "what way?"
