Homo sapiens

The prototype is still spitting out terrifying plasma.

During this period, Carl's team successively tested the extreme operation, low-power operation, engine power adjustment, and power adjustment of the power generation system of the power generation system.

When Carl's team designed it, the initial design plan was a Levi's ring and a spiral magnetic field device.

But during simulation tests, they discovered that a Levi's ring is not only huge in size and weight, but once it malfunctions, it means the spacecraft loses power.

In order to solve these problems, they studied more than a hundred solutions, and after supercomputing simulation tests hundreds of trillions of times.

This system was finally designed.

The six Levi's rings are not only convenient for maintenance, even if five of them are broken, as long as one can still work, the spacecraft will not lose power.

In addition, the parts of the Levi's ring device are all universal. In case of an emergency, you can find some usable parts among the faulty Levi's rings. Maybe two damaged Levi's rings can be pieced together to make a good one. of.

The test of the power generation system composed of Levi's rings went very smoothly.

In the open spiral magnetic field device, some problems occurred in the nitrogen-rich plasma project tested.

The reason is that nitrogen is not easy to ionize.

"It seems that the plasma engine needs to be adjusted." Carl bit his capacitive pen and thought.

Mikoyan reminded: "I heard that there is a laboratory over there on Venus that has developed an efficient ionization electric field. You can contact them."

"Oh? You can learn from that."

In fact, the engine studied by Carl's team is for generation spacecraft, so the working medium of this engine must not be fixed on one or two elements.

For example, many Hall engines can only choose xenon as the working fluid for efficiency. However, the content of xenon in the universe is not high, so it is very troublesome to enrich and refine it.

Carl hopes to integrate a plasma engine whose working fluid can use elements 1 to 26, including iron.

In this way, the working fluid required by the engine does not need to be specifically searched for. When encountering asteroids and planets, the materials can be quickly obtained locally.

The generation spacecraft must not be too picky, otherwise it will not be able to endure the long flight that started decades ago.

Using this prototype as the power standard, it would only take about 150 years to fly from the earth to the six-clawed giant star.

It only takes about 200 years to get to the parallel system.

At present, the life span of new humans is about 150 to 170 years. Using absolute zero freezing technology, the life span can be extended by hundreds of years.

In this way, Homo sapiens companies can colonize the Proxima system.

However, the company's management currently has no relevant plans.

Instead of building generations of spaceships to cross the planetary system, it is better to continue farming in the solar system and try to see if we can break through the technology of light speed navigation.

In Li Qingye's view, it would be difficult for a first-level civilization without light-speed navigation technology to colonize other planetary systems unless the distance between the two parties is within one light-year.

But the solar system is in the Orion spiral arm, not in the core of the Milky Way. The distance between the planetary systems here starts at a few light-years, and there are very few two planetary systems within one light-year.

With a distance of several light-years and no light-speed navigation technology, sending a generation spacecraft to colonize the interstellar space is simply too cost-effective, and there is a risk of loss of control and separation.

After all, there is nothing for one or two generations. Once it exceeds five generations, the human forces between the two planetary systems will inevitably become at odds.

Instead of sending generation ships, we should send out the spark of civilization.

Of course, Generation Spaceship Technology Company will definitely continue to invest in research. After all, this is one of the fallback options for mankind.

If something goes wrong in the solar system one day, or if it encounters a powerful first-level civilization, at least the company can still escape.

Homo sapiens never lets up when it comes to planning for a rainy day.

Of course, the engines studied by Carl's team will also greatly improve transportation within the solar system.

Mikoyan saw that there were no major problems in the test, so he asked Karl's team to continue their efforts, and he went to inspect another project.

After 17 hours of trial operation.

Suddenly an alert pops up on the test system.

[Local deterioration of the neutron absorbing layer detected...]

Karl frowned: "Continue testing."

He then took several colleagues to inspect the deterioration of the neutron absorbing layer.

A researcher said with some helplessness: "The degradation rate is much faster than the predicted model. If this degradation rate is followed, it is estimated that the entire neutron absorption layer can only last for 30 to 40 days, and it must be replaced with a new one."

"What do you think?" Karl turned to the others and asked.

Huang Xiaoyu, a researcher in plasma hydrodynamics, carefully looked through the data. He saw that the degradation was not comprehensive, but small local points, which showed that the neutron flow was extremely irregular.

He input some data again, substituted it into the plasma operation model, and quickly analyzed an unexpected reason.

Huang Xiaoyu's face was full of disbelief: "The gravity of the moon? It's actually the gravity of the moon?"

"Gravity?" Karl was also very surprised.

In the simulation analysis of the model, it can be clearly seen that the nuclear fusion defense process bound by the magnetic field, the high-energy neutrons ejected, are disrupted by the interference of the moon's gravity.

This chaos is very troublesome, because it will lead to uneven local distribution of high-energy neutrons, causing a part of the neutron absorption layer to rapidly deteriorate.

"What to do?"

"We do not have current efficient gravity adjustment technology unless we go to outer space to test it."

"There is actually no way to completely avoid the interference of gravity in outer space."

A group of researchers fell into hard thinking.

There are actually only two roads before them now.

One is to use thicker lithium carbon nanolayers.

The other is to adjust the magnetic field to make the nuclear reaction more uniform, thereby making the ejected neutrons more even.

Increasing the thickness of the lithium carbon nanolayer may seem like nothing, but it is actually very troublesome.

Because when Carl's team designed this plan, they took into account the amount of lithium carbon produced during the nuclear fusion reaction, combined with the service life of the lithium carbon nanolayer.

About 70 days is an optimal value. During the nuclear fusion reaction, the newly generated lithium carbon elements are just enough to make up for the elements in the lithium carbon nanolayer.

It is not that the lithium carbon elements in the lithium carbon nanolayer disappear, but that a large part of these elements are converted into radioactive isotopes.

Radioactive isotopes of lithium carbon cannot be used as neutron absorbing layer materials.

Therefore, the best solution now is to adjust the binding magnetic field and acceleration tail field to make the nuclear fusion reaction more uniform. This is the fundamental solution.

Otherwise, when it comes to interstellar voyages across planetary systems, this problem will be quickly amplified due to the resource-scarce environment.

Just adjusting the magnetic field binding model and tail field acceleration model needs to be adapted to local conditions, because there are subtle differences in the gravity at various points in the universe.
