Technology's opening live broadcast to build rockets

"Changing the microstructure of molecules." Du Xingyu said, this is the conclusion he came to after spending tens of millions of energy points on a technological simulator.

"You mean, something like magic angle graphene?" Zhou Ziang asked tentatively.

"Yes." Du Xingyu nodded and continued: "We all know that conventional superconductors need to be formed at extremely low temperatures. In nuclear fusion reactors with hundreds of millions of degrees Celsius, such low-temperature conditions do not exist."

"So we have to look for superconductors that can exist at high temperatures, have zero resistivity, are completely diamagnetic, and have flux quantization."

"Theoretically, ultra-high pressure can be used to create 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 is a material that can make this insulating material exhibit superconducting phenomena when the double-layer graphene is placed at a magic angle of 1.1° under a magnetic field and a temperature of 1.7K... Based on this conjecture, the molecular structure The change will also make the material become a superconducting material, and the requirements for temperature and atmospheric pressure conditions will be reduced."

"That's true, but we haven't found such material yet." A researcher said.

"I have discovered something." Du Xingyu said, "Some insulator materials similar to carbon materials will also show superconducting properties after their molecular structure is modified, and can exist at normal temperatures and pressures or high temperatures and high pressures..."

"Really?" Everyone was shocked, and Zhou Ziang said eagerly: "If we really find this kind of superconducting material, we can solve at least 30% of the problems!"

"I have several theoretical models, but they have not been produced yet." Du Xingyu turned on the computer and began to share with everyone the molecular simulation structures obtained on his simulator.

In addition to superconducting materials, he also simulated high-temperature-resistant materials used to withstand the impact of neutrons in nuclear fusion reactions and thousands of degrees Celsius when plasma disintegrates.

It can be said that the biggest obstacle standing in the way of controllable nuclear fusion technology is the problem of materials!

For more than a year, Du Xingyu spent 80% of his time simulating materials. Sometimes materials that have been successfully simulated are theoretically feasible, but cannot be manufactured with human technology; some can be manufactured, but the cost is too high; there are even some that need to be manufactured but require breakthroughs in other technological fields... …

All in all, in order to simulate these new materials, Du Xingyu estimated that he conducted millions of simulation tests on the technology simulator.

…

Three years later, it was also the fifth year since Du Xingyu announced the discovery of the Death Star.

The Sky Elevator has been operating successfully for two years. The second space elevator has also begun construction in the Pacific Ocean and is jointly funded by European and American countries. Their speed is slower than that of China. It takes two years to build the artificial island. It is expected that it will take another year to be fully completed.

Correspondingly, the United States launched a new International Space Station. With the investment of the entire world and the help of the Science Society of the Human Guardian Alliance, the aerospace technology of various countries has made great strides, but compared to China, it is not worth mentioning.

The main part of the near-Earth space port has been built, and it can now park, inspect and repair spacecraft in space, and transfer materials.

Regarding the Earth's outer space defense system, including the lunar base, only China in the world has a completely independent system.

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

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

The private enterprise Xingyao has been able to build its own Mars spacecraft. Rich people from all over the world are queuing up to place orders. There are even big forces secretly paying for it, hoping to build a "doomsday ark".

Chengfeng Space Technology Services Company has also developed into the world's largest space technology company, with business involving space transportation, travel, communications, industry, etc.

This is true for commercial space companies, and the national Aerospace Science and Industry Group is even more impressive. It is said that it is designing and manufacturing the world's first space battleship!

According to statistics, in China, a spacecraft is built every five days on average! In five years, I have owned more than 300 spacecrafts, all of which are capable of transporting Earth and Mars.

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

Ten years ago, there would have been endless debates about this internationally, but today, five years later, no one is arguing about it.

The Nemesis observed by the space telescope is getting closer and closer, and its orbit has been determined to be undoubtedly heading towards the earth. The direction is hopelessly accurate!

The 523rd meeting of the Human Guardian Alliance, this time is an important meeting, lasting for five days, will select the supreme commander of the Human Guardian Alliance who has been inactive for five years and the next self-rescue plan for mankind.

Because not long ago, the latest observational results showed that due to the influence of the gravity of the sun and the gravity of other planets, the speed of Nepheus flying towards the earth has increased!

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

"According to the current speed, Nemesis will reach the orbit of Mars in 13 years. We only have 13 years!" At the meeting, the chief executive of the European Southern Observatory announced.

"Although we have built space elevators and more outer space defense equipment and spaceships in the past few years, our progress in the most critical technology, controllable nuclear fusion, is limited," said the president of the International Thermonuclear Fusion Organization. , "The best news at the moment is that the US National Nuclear Energy Research Laboratory has just achieved a fusion reaction with a Q value (energy gain effect) of 20 times and a length of 47 minutes."

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

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

Theoretically speaking, only when the Q value produced by the fusion reaction is more than twenty times, can it be valuable.

Although countries are engaged in technological exchanges, the nuclear fusion devices built by each country are different, and the energy gain effects produced are naturally different.

"We are conducting a new stage of fusion experiments." said a Chinese atomic energy expert. "Academician Du is absent from this meeting for this reason. As expected, he will make it to the last day of the meeting."

"I'm very confused." A nuclear expert from the Mao Xiong Country asked, "In recent years, you have given up on building super-large circulation devices, and instead studied miniaturized nuclear fusion reactors... I wonder what the effect will be?"

The current international consensus is to build large-scale nuclear fusion reactors first to obtain enough energy to complete space defense construction.

"We have gained something, and everyone should know it in the past few years." said a Chinese atomic energy expert.

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

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

It’s just that little is known about the new fusion device they built. I only know that in the past few years, Du Xingyu, as the general consultant of International Science, has rarely appeared and has been involved in this project.

"Okay, everyone, since Mr. Du can't be here these two days, let's first discuss the modifications to the "Death Planet Crisis Response Plan" and the preliminary selection of the highest command of the Human Guardian Alliance." A member said.

While they were having a heated discussion, Du Xingyu and a group of nuclear physics experts were testing the newly built spherical tokamak device at the fusion test site of the China Institute of Atomic Energy.
