Chapter 3331

"With regard to the fourth technology, it is not a space technology in itself, but a technology for launching massive objects." I explained: "as we all know, launching a spacecraft is a very energy consuming activity. For example, it is quite difficult for us to launch only a few tons of satellites. In the space age, the self weight of many large space warships may exceed 10000 tons. Although the power of this class of spacecraft will be very strong, but if it depends on its own power to leave the surface of the planet is really very energy consuming. Therefore, some planets will be equipped with special devices to help large tonnage spacecraft take off. "

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

"In fact, it's not a special device. It should be similar to an electromagnet. The difference is that it's directional and uses gravitational waves instead of magnetic fields."

"Gravitational waves?"

"Yes. Simply put, a giant gravitational wave generator is set up on the earth's surface, and then the spacecraft that needs to go into space can enter the upper area of the device. When the device is started, it will generate an upward gravitational wave, supplemented by a special repulsion field, which can send the spacecraft directly into space without starting its own engine.

This technology is widely used on the creator's planet, and its launch cost per unit mass is higher than that of space elevator, but its own construction cost is very low, the construction difficulty is also very small, and the maintenance is simple. The most important point is that the rail elevator can transport scattered goods or small spacecraft that can be loaded into containers, but for some large spacecraft, the rail elevator is obviously not suitable. This kind of device is just complementary to the rail elevator. It is a kind of launch device with high safety and low construction cost. The creators' military launch systems are basically based on this, and rail elevators are more like civilian technology.

As far as our current situation is concerned, we don't have enough technology to complete the rail elevator, and even if we have that technology, we don't have the time. But this launcher is very simple, and according to my estimation, we can do at least a few thousand of them around the world without affecting other construction projects. "

"So what's the use of this launcher?" Asked a tycoon.

"It's a lot of use. For example, the spacecraft can go directly into space without consuming any fuel, which means that our spacecraft can save some more fuel. In addition, because of this technology, all immigration ships we will build from now on can be modified to reduce the fuel tank size and make room for more sleeping cabins. In this way, more people can be taken away without additional workload. Don't you think that's a good thing? Even if the space saved does not need to be filled with people, it is a good choice to take more resources and equipment. Don't you want to take away all the antiques, famous calligraphy and paintings on earth? "

When I heard the last part of my speech, the big guys obviously reacted differently.

No matter what degree of social development, there is no real equality between people. Although due to the great crisis of human extinction, all countries have made great efforts to reserve space for manned use. But even that doesn't mean the tycoons will leave empty handed. Many of them have actually planned to leave with jewelry, antiques, calligraphy and paintings, and they really have the ability to take some of these valuables. But even if these tycoons have the ability to carry these things, they still can't take away all their collections, because even they have to compromise in the face of the great crisis of human extinction, so each of them may take less than one third or even one fifth of their collections.

These big guys don't think about this kind of thing? Of course not. So, when they heard that a lot of space could be made available, these people immediately got excited.

What they don't know is that the space saved on these ships is actually much larger than they thought.

Although these immigrant ships under construction all over the world generally use the super electromagnetic engine and the thrusters left by aliens, they still need to use human rocket assisted technology to launch when taking off. And the rocket boost technology has many holes, perhaps some people know. We can see how big the Rockets were when we launched the satellites, but how big were those rockets? A rocket is dozens of stories high, and the satellite only accounts for one percent of its volume. The rest of the space is basically a fuel tank.

If the immigrant ship can enter space without its own power, that is to say, we can not only reduce the volume of the fuel tank, but also can directly omit this part without installing rocket booster equipment.

If it did, it would mean that today's immigrant ships would be able to maintain their original performance without losing a third of their volume. What's the concept of one third of a ship's volume? It's not just volume, it's weight. This means that the construction cost and construction period of the new immigrant ship will be shortened by a large section, but the performance will be improved slightly. If the volume is not reduced, then the extra one-third of the internal space can be filled with two sets of auxiliary thrusters, more people, or more spare parts.I don't intend to introduce these details to them here. Anyway, they will certainly ask themselves in the future. Of course, this kind of modification can only be applied to the ships that have not yet been completed. If the immigration ships that have been completed are reworked, the time will be delayed. It is better to build more new ships.

In fact, I personally think that it is not bad to retain some immigration ships with large thrusters. In fact, the output power of the super electromagnetic engine we are using is very small. It is OK to accelerate for a long time in space and maintain stable endurance. However, the explosive force is not enough. In case of emergency, it is difficult to correct the trajectory of the ship. The power output of those engines removed from the remains of aliens is very good. Unfortunately, these things are not enough. What's more, we installed the thrusters used by small spaceships into large spaceships, which is a little bit of a horse pulling a cart. Even if the thrust of other people is very large, it is still relatively small compared with the original size, which is not enough for large spaceships.

Although human rocket propulsion has many shortcomings, but at least one thing is very good, that is, the explosive power is very high. Now that you can't use rockets to launch a spaceship, you can save the fuel for emergency use.

Of course, only these old migrant ships can do emergency avoidance, and the newly built ones will not have such an opportunity. However, I am not worried about this, because according to the immigration plan, the population in the process of immigration should be less and less.

According to the immigration plan, all the people who have been taken away will enter the dormant cabin after the immigration starts, and then these people's thinking consciousness will be connected to the game world of "zero" to survive and reproduce in it. At that time, the offline function of 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 to have children, the extractor in the outer dormancy chamber will extract germ cells from the two people respectively, and then the automatic equipment will complete in vitro fertilization. After the embryo is stable, it will be re implanted into the mother. During this period, the mother will be moved into the special sleeping cabin for pregnant women. This kind of dormancy chamber has a larger volume. Many corresponding devices are specially prepared for pregnant women and fetus, such as those for fetal education and auxiliary delivery.

During the pregnancy of the fetus, the female players in the game will have synchronization effect, that is to say, the real reactions of the game characters and the outside world will appear synchronously, such as pregnancy reactions such as vomiting and abdominal pain. When the actual fetus gives birth, the game will also be synchronized. When the delivery is completed, the fetus and the mother will stay in the special sleeping cabin for pregnant women for a month. During this period, the special dormancy cabin will provide professional automatic nursing for the fetus and pregnant women. Moreover, the biggest difference between this kind of dormancy cabin and the general dormancy cabin will also be reflected, that is this Sleep module can allow pregnant women and fetus to access the game at the same time, while the general dormancy cabin can only allow one person to access the game.

After one month, the fetus and mother will be removed from the sleeping cabin for pregnant women. The mother will return to the previous ordinary cabin, and the baby will be sent to the special sleeping cabin for infants and young children. Until the baby reaches the age of three, he or she will access the game in the special sleeping cabin for infants and young children, and will not be transferred to the ordinary cabin until he or she is three years old. Of course, people in the game can't feel the transition of these sleeping cabins. The state of the game will be like in reality, giving birth to children directly, and then slowly bringing up the children. This process will not change.

This whole set of procedures can ensure the normal reproduction of human beings. However, according to the plan, after the immigration starts, human beings will implement the comprehensive family planning policy. Since the number of dormant cabins has been constant at the time of takeoff, there is no way to build more sleeping cabins on the way. Even if you bring a small number of spare ones, you should also take into account the damage of the sleeping cabins. Therefore, the population must be controlled, or it will be troublesome for the newborn to come out without a sleeping chamber.

These immigration boats are designed according to the fact that human beings have been in a dormant state. If someone leaves the dormant state, it means that his consumption will exceed that of normal people, because people can't lie still all the time after offline, and once the muscles are active, the energy consumed is definitely much more than that in the dormant state. What's more, people who wake up need more space, and there's not so much space on the ship. What's more dangerous is that if someone does something harmful to the safety of the spacecraft because of boredom or some motive, it will be even worse. If a person's nerves are not well done, it means that tens of thousands of people will be buried with a boat. No one can afford the loss.

Therefore, the simplest and most practical way is to control fertility.

In fact, the birth rate of European countries has not been very high, and the probability of accidental pregnancy will be reduced to zero after immigration. As long as you do not apply for birth, the system will not collect germ cells for you to breed embryos. If you love each other in the game, it should actually be called "divine friendship". No matter how much this kind of thing is done, there will be no children.

Because the developed countries have the ability to build a large number of immigration ships, those countries with a frightening birth rate can't walk a few people. However, the population birth rate of developed countries is already low. As long as we make some policy preferences in the game, requiring a couple to have only one child, if they want to have more lives, they need to spend money to buy them, or they have to do difficult tasks in the game We are setting some barriers to limit the second child. In this way, only one offspring will be produced for every two adults, so that the population will be less and less if the generations continue to reproduce.Of course, we won't let the number of humans fall below the warning line, but eventually we'll keep the population on the immigration ship at about one tenth of what it was when we took off.

It's humanitarian for the spacecraft to take everyone with them when they take off, while population control after takeoff is a necessary action. Moreover, one tenth of the final population standard is also a calculated conclusion.

As the whole process of immigration may be as long as thousands of years, during this period, our immigration ships will inevitably encounter various problems. It's no big deal when we first take off, but after several hundred and thousands of years, the proportion of equipment aging and damage on immigration ships must be very high.

In space, we can't build new equipment to replace it, so all we can do is tear down Peter to pay Paul.

As the immigrant population declines, we can make some of the equipment stand-by. Dismantle the replaced damaged equipment, and reserve the available parts for repairing other damaged equipment. In this way, the support time of the equipment will certainly be longer. Moreover, if necessary, we will even dismantle some of them to repair the damaged ones. In any case, the arrival time of the fleet is quite different from the expected one in the future. If all these boats are full, then we will have to face the multiple-choice question of giving up some people. If we don't want to make this choice, we can only have family planning ahead of time. In this way, when the equipment or spaceship is damaged and some spaceships need to be abandoned, we can concentrate the population, and then dismantle the empty ship without any people. Isn't it more leisurely?

As long as family planning is implemented, the population will drop rapidly. After several hundred years, most of the spaceships will have no problem, but the population will certainly have been reduced a lot. By then, those spaceships with additional rocket propellers can be hit and used. We can even accelerate the fleet again to make the fleet reach the destination faster. It can be said that these are predictable things.

Listening to my beautiful blueprint, all the tycoons were very excited. They were all there to calculate what Dora would like to go.

After they calmed down a little bit, I continued to speak and made a summary of this contact. After that, these guys went to their men to discuss how to make good use of these technologies. As for me, I came to the pilgrims again because they had something to talk about with me.

Before the mind network connection only transmitted knowledge and memory and so on. Ideas still need to be communicated, which can't be copied.
