"Change the microstructure of molecules," said Du Xingyu, who spent tens of millions of energy points on science and technology simulators.

    "You mean like magic horn graphene?" Zhou Ziang asked tentatively.

    "Yes." Du Xingyu nodded and continued, "we all know that conventional superconductors need to be formed at a very low temperature. In a nuclear fusion reactor with hundreds of millions of degrees Celsius, there is no such low temperature condition."

    "So we have to find superconductors that can exist at high temperatures. They have the properties of zero resistivity, complete diamagnetism and flux quantization."

    "In theory, ultra-high pressure can be used to make high-temperature superconductors, but the atmospheric pressure required is comparable to the pressure in the center of the earth, such as superconducting hydrogen under high pressure."

    "Magic angle graphene can make this insulating material superconducting when the double-layer graphene is placed at a magic angle of 1.1 ° under the condition of magnetic field and 1.7k temperature... It is speculated that the change of molecular structure will also turn the material into superconducting material, and the demand for temperature and atmospheric pressure will be reduced."

    "That''s right, but we haven''t found such materials yet," said a researcher.

    "I have a little discovery," said Du Xingyu. "Some insulator materials similar to carbon materials will also show superconducting properties after molecular structure transformation, and can exist at room temperature and pressure or high temperature and high pressure..."

    "Seriously?" everyone was surprised, and Zhou Ziang said eagerly: "if we really find this superconducting material, we can solve at least 30% of the problem!"

    "I have several theoretical models, which have not been manufactured yet." Du Xingyu turned on the computer and began to share the molecular simulation structure obtained from his simulator with the public.

    In addition to superconducting materials, he also simulated high-temperature materials used to withstand neutron impact in nuclear fusion reaction and thousands of degrees Celsius during plasma disintegration.

    It can be said that the biggest difficulty in front of controllable nuclear fusion technology is the problem of materials!

    Du Xingyu spent more than a year simulating materials. Sometimes materials that simulate success are theoretically feasible, but they cannot be manufactured with human technology; Some can be manufactured, but the cost is too high; Some even want to be manufactured and need to make breakthroughs in other scientific and technological fields

    In a word, in order to simulate these new materials, Du Xingyu estimated that millions of simulation tests had been carried out on the science and technology simulator.

    ……

    Three years later, it was also the fifth year after Du Xingyu announced the discovery of the death star.

    The skylift has been running successfully for two years, and the second space elevator has been built in the Pacific, jointly funded by European and American countries. Their speed is a little worse than that of China. It takes two years to build the artificial island. It is expected that it will take another year to complete it.

    Correspondingly, the United States launched a new international space station. With the input of the world force and the help of the Science Society of the human Guardian alliance, the aerospace science and technology of various countries have made great strides, but it is not worth mentioning compared with China.

    The main part of the near earth spaceport has been built. At present, it can park, repair spacecraft and transfer materials in space.

    For the earth outer space defense system, including the lunar base, only Huaxia has a completely independent system in the world.

    On the Mars base, nearly 80% of Chinese astronauts and construction personnel also account for.

    In the construction of satellites and spacecraft, China is the first country to form an industrialized satellite and spacecraft industry chain.

    Xingyao, a private enterprise, has been able to make its own Mars spacecraft. Rich people all over the world are lining up to place orders, and even big forces secretly pay money in the hope of building a "doomsday Ark".

    Chengfeng space technology service company has also developed into the world''s largest space technology company, whose business involves space transportation, travel, communication, industry and so on.

    Even so for commercial space companies, the National Aerospace Science and industry group is even better. It is said that it is designing and manufacturing the world''s first space warship!

    According to statistics, in China, on average, one spacecraft is manufactured every five days! In five years, we have more than 300 spacecraft alone, all of which can carry out transportation from earth to Mars.

    It can be said that China is now the world''s strongest space power.

    If it had been ten years ago, the international community would have been arguing about it, but today, five years later, no one is arguing about it.

    The space telescope observed that the death star is getting closer and closer. Its orbit has been determined to face the earth. There is no doubt that the direction is desperate!

    The 523rd meeting of the human Guardian alliance, which is an important meeting for five days, will elect the top commander of the human Guardian alliance who has been shelved for five years and mankind''s next self rescue plan.

    Because not long ago, the latest observation results showed that the speed of Death Star flying to the earth increased due to the influence of the gravity of the sun and other planets!

    In other words, the time left for them will be reduced again!

    "At the current rate, in 13 years, the death star will reach the orbit of Mars. We have only 13 years!" announced the chief of the European Southern Observatory at the meeting.

    "In recent years, although we have built space elevators and more outer space defense equipment and spacecraft, we have made limited progress in the most critical technology, controllable nuclear fusion." the president of the international thermonuclear fusion organization said, "at present, the best news is that the National Nuclear Energy Research Laboratory of the United States has just realized the Q value (energy gain effect) 20 times, up to 47 minutes of fusion reaction. "

    "It can be said that this is the most promising nuclear fusion device for mankind."

    "At present, except for the unclear fusion test data in China, the Q value of fusion reaction in various countries has not reached 5. It is far from enough!"

    Theoretically, only when the Q value produced by fusion reaction is more than 20 times, it can be used.

    Although countries are exchanging technology, the nuclear fusion devices built in each country are different, and the energy gain effect is naturally different.

    "We are conducting a new stage of fusion test," said the Chinese atomic energy expert. "Academician Du is also absent from the meeting for this reason. Not surprisingly, he will catch up with the last day of the meeting."

    "I''m very confused." a nuclear expert in Maoxiong asked, "in recent years, you have given up building super large circulation devices and studied miniaturized nuclear fusion reactors instead... I don''t know the effect?"

    At present, the international consensus is to build large-scale nuclear fusion reactors first and obtain enough energy to complete the construction of space defense.

    "We have gained something. Everyone should know in recent years," said an atomic energy expert in Huaxia.

    He did not disclose more, because he knew that if the experiment was successful, the results would subvert the whole human civilization!

    Everyone nodded. Some ideas and new materials they provided these days really made nuclear fusion technology advance by leaps and bounds.

    But little is known about the new fusion device they built. Only know that in recent years, Du Xingyu, as the general adviser of international science, has rarely appeared and has been participating in this project.

    "Well, ladies and gentlemen, since Mr. Du can''t arrive these two days, let''s first discuss the revision of the Death Star crisis response plan and the primary election of the supreme commander of the human Guardian alliance," said a member of the Committee.

    During their heated discussion, Du Xingyu and a group of nuclear physics experts are testing the newly built Spherical Tokamak at the fusion test site of the China Institute of atomic energy.
