"About the fourth technology, it is not space technology itself, but a technology for launching large-scale objects." I explained: "Everyone knows that launching spacecraft is a very energy-consuming behavior. For example, it is quite difficult for us to launch satellites weighing a few tons now. In the cosmic era, many large space warships may weigh more than 10,000 tons. Although spacecraft of this level will also be very powerful, it is indeed very energy-consuming if they rely on their own power to escape the planet's surface. Therefore, some planets will specially set up some devices to help take off large-tonnage spacecraft."

"What kind of device is it?" someone asked.

"In fact, it is not a special device. It should be similar to an electromagnet. The difference is that this thing is emitted in a directional manner and uses gravitational waves rather than magnetic fields."

"Graining Wave?"

"Yes. To put it simply, it is to set up a huge gravitational wave generation device on the surface of the earth, and then let the spacecraft that needs to enter space enter the upper area of ​​the device. When this device is activated, an upward gravitational wave will be generated, and it is supplemented with a special repulsive field boost. The spacecraft can be sent directly into space without starting the engine of the spacecraft at all.

This technology is widely used on the planets of the creators. The launch cost per unit mass is higher than that of space elevators, but its own construction cost is very low, the construction difficulty is very small, and the maintenance is simple. The most important point is that the orbital elevator can transport scattered cargo or small spacecraft that can be loaded into containers can also be transported. However, for some large spacecraft, the orbital elevator is obviously inappropriate. This device just complements the orbital elevators, and is a launch device with high safety and very low construction cost. The military launch systems of the creators are basically based on this, and the orbital elevator is more like civilian technology.

As for our current situation, we don’t have enough technology to complete the track elevator. And even if there is that technology, there is no time left. However, the structure of this kind of launch device is very simple. According to my estimate, we can complete at least a few thousand of these things around the world without affecting other construction projects."

"So what is the use of this kind of launch device?" asked a tycoon.

"It's a lot of uses. For example, the spacecraft can enter space directly without consuming any fuel. This means that our spacecraft can save more fuel. In addition, because of this technology, from now on, all the immigration ships we built can be redesigned, reducing the size of the fuel tank and freeing up some space to store more dormant pods. In this way, we can take away more people without adding additional workload. Don't you think this is a great thing? Even if the saved space is not used to hold people, it is a good choice to bring more resources and equipment. Don't you want to take away the antiques on the earth, famous calligraphy and paintings, etc."

After hearing my last words, these big guys obviously had a different reaction.

No matter how society develops, it is impossible for people to be truly equal. Although all countries have made up their minds this time because of the great crisis of human extinction, immigration ships must try to keep the space for manned use. However, even so, it does not mean that these tycoons will leave empty-handed. Many of them have actually planned to carry some jewelry, antiques, calligraphy and paintings and other things. And they are indeed capable of taking away some of these valuable items. However, even if these tycoons have the ability to bring these things, they still cannot take away all their collections, because even they have to compromise in the face of the great crisis of human extinction, so what each of them can take away may be less than one-third or even one-fifth of their collections.

Will these big guys have no idea about such things? Of course not. So, when they heard that they could make a lot of space, these people immediately became excited.

In fact, what they didn't know was that the space they could save on these spaces was actually much larger than they thought.

Although these immigrant ships being built by countries around the world generally use ultra-electromagnetic engines and the propellers left by aliens, they still need to use human rocket boost technology to help launch during takeoff. Some people may know how crap the rocket is. Everyone can see how big the rockets are when launching satellites, but how big are those rockets? A rocket is dozens of floors high, and the satellite accounts for only one percent of the volume, and the remaining space is basically fuel tanks.

If the immigration ship can enter space without relying on its own power, it means that we can not only reduce the volume of the fuel tank, but also do not install rocket boosting equipment at all, and directly save this part.

If this is true, it means that the current immigration ship can keep its original performance unchanged while removing one-third of the volume. What does this mean? What is saved is not only the volume, but also the weight. This means that the construction cost and construction cycle of the new immigration ship will be shortened by a large amount, and the performance will be slightly improved. If the volume is not reduced, then the extra one-third of the internal space can be filled with two sets of auxiliary thrusters or bring more people, or it is also good to prepare more spare parts.

I don't plan to introduce these specific situations to them here, anyway, they will definitely ask them in the future. Of course, this modification can only be used for spacecraft that have not been built yet. If those immigrant ships that have been completed are reworked, it will delay time. It is better to build more new ships than to have the effort.

Actually, I personally think that it is not bad to retain some immigration ships with large thrusters. The output power of the ultra-electromagnetic engine we currently use is actually very small, and it is okay to accelerate for a long time and stabilize the battery life in space, but the explosive power is not enough. In case of an emergency, it is difficult to correct the vessel movement trajectory. The output power of the engines removed from the alien ruins is very good. Unfortunately, the number of these things is not enough. Moreover, they were originally thrusters for small spacecraft, but they were installed on large spacecraft by us, which was a bit like a small horse pulling a big cart. Even if the thrust is very strong, it is still relatively large. It is still a bit insufficient for large spacecraft.

Although humans' own rocket propellers have many shortcomings, at least one thing is that they have high explosive power. Since the rocket boost is not used when launching spacecraft, they can completely save the fuel for use until an emergency moment.

Of course, only these old immigration ships can be used for emergency avoidance, and the newly built ones probably won’t have such an opportunity. But I am not worried about this. Because according to the immigration plan, the population during the immigration process should be smaller and smaller.

According to the immigration plan, after the immigration begins, all the people taken away will enter the dormant compartment, and then the thinking consciousness of these people will be connected to the game world of "Zero" and survive and reproduce. At that time, the offline function of the ordinary account will be cancelled, and everyone will be left in the game forever. If two people fall in love in the game and want children, then the extractor in the dormant compartment outside will extract germ cells from the two people, and then the automatic equipment will complete in vitro fertilization, and then the embryo is stabilized and re-implanted into the mother for pregnancy. During this period, the mother will be moved into the dormant compartment for pregnant women. This dormant compartment is larger in size and specially prepared a lot of corresponding equipment for pregnant women and fetuses. For example, equipment that can educate the fetus in prenatal education and equipment that assist childbirth.

During the fetus pregnancy, female players in the game will have a synchronous effect, which means that the game characters will have real reactions synchronized with the outside, such as morning sickness, abdominal pain and other pregnancy reactions. When the fetus is delivered in reality, the game will also be synchronized. After the delivery is completed, the fetus will stay in the pregnant woman's dedicated dormant compartment with the mother for one month. During this period, the dedicated dormant compartment will provide professional-level automatic care for the fetus and pregnant women, and the biggest difference between this dormant compartment and the general dormant compartment will also be reflected, that is, this dormant compartment can allow pregnant women and the fetus to access the game together at the same time. The general dormant compartment can only allow one person to access the game.

After one month, the fetus and mother will be removed from the dormant compartment of pregnant women, and the mother will return to the previous ordinary compartment. The baby will be sent to the dormant compartment for infants and toddlers. Until the baby grows to three years old, he (she) will be connected to the game in the dormant compartment for infants and toddlers, and will not be transferred to the normal compartment after three years old. Of course, people in the game cannot feel the transition of these dormant compartments. The state in the game will give birth to a child directly like in reality, and then slowly raise the child. This process will not change.

This complete process can ensure the normal reproduction of human beings, but according to the plan, after immigration begins, human beings will implement a comprehensive family planning policy. Because the number of dormant cabins is constant during takeoff, and there is no way to build more dormant cabins on the way. Even if a small amount of spares are brought with them, the damage to the dormant cabin must be considered. Therefore, the population must be controlled, otherwise it will be troublesome if there is no dormant cabin after the newborn comes out.

These immigrant ships are designed according to the fact that humans have been dormant. If someone leaves the dormant state, it means that their consumption will exceed the consumption of normal people, because after going offline, people cannot lie down and move. Once the muscles move, they will definitely consume more energy than the dormant state. Moreover, the people who wake up need more space, and there is not so much space on the spacecraft. What's more dangerous is that if someone here does something that endangers the safety of the spacecraft due to boredom or some motivation, it will be even worse. If a person is nervous, it means that tens of thousands of people will be buried with him in a boat. No one can bear this loss.

Therefore, the easiest and most practical method is to control fertility.

The birth rate of European countries has never been very high, and the probability of unexpected pregnancy after immigration begins will also be reduced to zero, because as long as you do not apply for childbirth, the system will not help you collect germ cells and nurture embryos. Just love in the game, it should actually be said to be "god friends". No matter how much you do this, there will be no children.

Because those who are able to build large quantities of immigration ships are developed countries, those countries with scary birth rates cannot actually leave a few people. The birth rate of developed countries is already low. As long as some policy preferences are made in the game, requiring a couple to have only one child, and if they want to have more children, they need to spend money to buy them, or they have to do difficult tasks in the game. Anyway, some levels are set to find ways to limit the second child. In this way, every two adults will only produce one offspring, and the population will become smaller and smaller as generations continue to reproduce.

Of course, we won't let the number of humans fall below the cordon, but in the end we'll keep the population on the immigration ship about one-tenth of the time of takeoff.

Try to bring everyone with you when the spacecraft takes off. This is out of humanitarianism, and controlling the population after taking off is a necessary action. Moreover, one-tenth of the final population standard is also a calculated conclusion.

Since the entire immigration process may last for thousands of years, our immigration ships will inevitably have various problems during this period. It is definitely not a big deal when they first take off, but after hundreds or thousands of years, the proportion of equipment on the immigration ships will be a very high.

In space, we have no way to build new equipment to replace it, so all we can do is to tear down the east wall and repair the west wall.

As the population of immigrants decreases, we can make some equipment a spare equipment. The replaced damaged equipment is separated, and the parts can be used to repair other damaged equipment. If repaired in this way, the equipment will support it longer. Moreover, when necessary, we will even dismantle some of the spacecraft to repair the damaged spacecraft. Anyway, this kind of thing must exist during the entire voyage, and it can be expected that the number of ships will be absolutely a big difference when the fleet takes off and when it arrives at the destination in the future. If all these ships are full, then we have to face the choice of giving up a part of the people's multiple-choice questions. If we don't want to make this choice, we can only plan for family planning in advance. When the equipment or spacecraft is damaged and some spacecraft needs to be given up, we can concentrate the population and then remove the empty ship without anyone. Wouldn't that be more calm?

As long as family planning begins to be implemented, the population decline will actually be very fast. In hundreds of years, most of the spacecraft should be fine, but the population has definitely decreased a lot. At that time, those spacecraft with additional rocket propellers can be hit and used. We can even have a second acceleration to allow the fleet to reach its destination faster. It can be said that this is foreseeable.

Listening to the beautiful blueprint I drew, the tycoons were all very excited, and they were all calculating what to pull away at that time.

After they calmed down a little, I continued to speak and summarized the contact. After that, these guys hurriedly went to discuss how to use these technologies well. As for me, I came to these pilgrims again because they still had something to discuss with me.
Chapter completed!
