Ultra-Dimensional Technology Era

The scientific committee, which is going all out, is vigorously developing various fields, and many projects have been launched one after another. No matter whether there is any gain or not, we must study first.

If there are 1 laboratories, only a hundred will get results after that, it will not be a loss for the new human beings and the scientific committee.

In the new era of extremely abundant materials and energy, new human beings have already broken away from the operating mode of the capital economy.

It is no longer the capital market that determines research and development, but civilization needs to determine research and development. This is an essential difference.

If the capital market operates controllable nuclear fusion and biological computers, it is estimated that the gap between rich and poor in human society and social solidification will further increase.

This is because the purpose is different, resulting in different results.

One is for money, the other is for civilization, the height of the two is very different.

Chapter 3 Hybrid Magnetic-Inertia

Huang Mingzhe stayed at the Lianhuashan Nuclear Research and Development Base for more than a week, only advancing multiple controllable nuclear fusion to the stage of sulfur atoms.

Sulfur atoms will face many technical problems afterwards, and the engineering will greatly increase the volume of the reactor. Obviously, this is a problem caused by unqualified materials.

"Material material! After all, it is a hurdle that cannot be overcome." Huang Mingzhe shook his head and said.

Dong Kuan patted him on the shoulder: "We have completed the theoretical design, and we can definitely come up with it next. It's just a matter of time."

However, Huang Mingzhe is not so blindly optimistic. Judging from the needs of theoretical design, the material performance of the reactor needs to be improved by at least 10 times before it can barely reach the minimum standard.

If miniaturization is to be satisfied, material performance needs to be increased by 30 to 50 times.

As a top scientist in materials science and a master of computational materials science, Huang Mingzhe knows that the materials science of new humans has entered a bottleneck period.

The bottleneck of atomic-molecular-scale materials has arrived as expected, which is what he expected.

This is a fundamental congenital limitation. Even if atomic-molecular-level materials are played out, they are still atomic-molecular materials, which are much weaker than degenerate neutron materials and quark materials.

"Old Dong, let you take care of the multiple controllable nuclear fusion. I want to deal with the matter of the nuclear fusion engine research institute."

"no problem."

As for Wei Feng, he has already put oil on his feet. He is not very interested in nuclear fusion. Huang Mingzhe dragged him here before. When he got to the carbon atom stage, he knew that nothing could be done.

Now that he is also in charge of two large physics projects, he naturally has no time to waste here.

Huang Mingzhe came to his office, put the substitute robot back into the storage cabin, and then left the nuclear research and development base.

In the unknown base, Huang Mingzhe, who had withdrawn from the virtual network, moved his body.

Come outside the base, here is a secret base built in the depths of Wuyi Mountain. Now the surrounding area of ​​Wuyi Mountain is already a natural scenic spot, and human activities are very few.

As the core area of ​​the new human race, the East Asia region will still retain a population of 4-5 million in the future.

Although it is an area of ​​human civilization, some ecologically fragile areas should be withdrawn.

For example, the Qinghai-Tibet Plateau, the Yunnan-Guizhou Plateau, and the mountainous regions of various regions will retain their populations except for the famous historical cities.

Beside this base is an abandoned town.

All the residents of the town relocated to Philadelphia, North America. It was a joke to say that it was difficult to leave their homeland. In the past, it was due to environmental restrictions. The country was overcrowded and there was nowhere to move.

Now the new humans occupy the entire Blue Star, relocating a lot of plain land, and there are many differences between the new humans' concepts and the old humans, and they do not reject migration.

Huang Mingzhe walked in the small town, Zhang Shihe followed him like a shadow to protect him.

The houses in the town are still preserved, but plastic products and household appliances have all been recycled.

On the mottled walls, lime pits reveal the red bricks underneath, and moss and weeds are encroaching on human remains.

Meow……

He looked up and saw a tabby cat with a cub staring at a stranger on the balcony on the second floor.

It has been less than a month since humans moved out here collectively, and wild animals and plants have begun to recover.

"Life is so great. Blue Star has never cared about human beings, and we don't need human beings to save us. We are just saving ourselves." Huang Mingzhe sighed.

Walking around, the traces of humans in this small town are disappearing, and the animals and plants are destroying the reinforced concrete and furniture that humans exist in.

Maybe after a few years, there will be no more small towns here.

"Let's go!"

Go back inside the base.

Huang Mingzhe entered the virtual network again and landed on the stand-in robot located in Qinhuangdao Nuclear Fusion Engine Research Institute.

Qin Changge, who is in charge of the management of this research institute, was the former head of the laser laboratory of Sisishe.

He introduced Huang Mingzhe's ideas for the next generation of nuclear fusion engines.

Huang Mingzhe quickly flipped through the materials of the institute while listening.

Generally speaking, a spacecraft engine needs two things to work—energy and working fluid.

In chemical energy rockets, the propellant is both father and mother, providing both propulsive energy and working medium for propulsion.

This seems to simplify the structure, but according to the law of conservation of momentum, the specific impulse of the rocket is proportional to the velocity of the ejected working medium, and there is an upper limit to the velocity of the ejected working medium of the chemical energy rocket.

The nuclear fusion engine is an engine that uses the energy generated by fusion to heat the working medium (the fusion product itself can also be used as the working medium) to generate propulsion.

In a fusion engine, there are three types of energy that come from fusion reactions: plasma heat, neutron energy, and bremsstrahlung energy.

Plasma thermal energy means that when the fusion fuel undergoes fusion, the fuel atoms are ionized into useful hot plasma ions, which contains most of the fusion energy and is also easy to use.

Many fusion reactions or side reactions produce lethal neutron radiation, and high-energy neutrons are also lethal to new humans.

In addition, prolonged neutron irradiation can lead to neutron embrittlement and neutron activation of engine components.

Neutron energy is in a semi-waste state in nuclear fusion direct injection engines.

Bremsstrahlung energy, on the other hand, mainly occurs when ions and electrons in the hot plasma from nuclear fusion reactions collide.

Useful plasma heat energy is converted into useless and dangerous X-ray chilled ions, which is also considered a waste of energy.

Huang Mingzhe knows that the engineering upper limit of a nuclear fusion engine is about 30% of the speed of light, but now it is difficult for humans to reach even 10%.

The main reason is that too much energy is wasted in the nuclear fusion direct injection engine, resulting in a very large fuel load ratio. It takes 12 tons of nuclear fuel to accelerate 100 tons of equipment to [-]% of the speed of light, and the fuel load ratio reaches [-].

That is, 1 ton of equipment needs 100 tons of fuel to accelerate, and too much energy and working fluid are wasted.

Huang Mingzhe has already understood Qin Changge's thinking: "Your plan is a hybrid model, which is a good idea."
