Chapter 70

As for the harvest of all kinds of metals, Lei Tiantang doesn't bother to count their specific quality. Anyway, he doesn't know how long it will take to use up the harvest now. He simply estimated that there will be more than 300000 tons of gold for six nines. How much of these gold can he take to the earth? It's not as useful as iron. At least, it can be used a lot in building his own underground laboratory.

With such a large harvest, Lei Tiantang finally has a passion for work. The universe is so big, I want to see it! If you want to go to the middle of the universe, you have to have a spaceship at least, and it has to be a super high-tech superluminal spaceship! Otherwise, if the conventional spaceship does not have a superluminal engine, it can only travel at a speed lower than the speed of light. Even if you fly faster, what can you do?

In the vast expanse of space, there are countless stars, among which the nearest star to the sun is called neighbor star. It is located in Centaurus, scientific name: alpha Centaurus C, only 4.22 light-years away from the sun, equivalent to 39923.3 billion kilometers. If we use the fastest spaceship to travel to neighboring star, it will take 170000 years to travel back and forth. We can imagine that the size of the universe, even if it is neighbor, is far away.

In this way, we should know the difficulty of waves in the universe? Even if we drive an ordinary spaceship to 0.99 times the speed of light, it will take more than 4 years to get to the neighboring star. It is the nearest galaxy to the earth. What's more, when can the spaceship reach such a speed?

Lei Tiantang has a lot of ideas on this point. He has no doubt that he can go to the waves in the universe, because he can handle the most important materials for building spaceships. There is no problem with what quality materials he wants. Of course, building a spaceship that can fly in the universe is a huge system engineering, but it's not just a matter of materials.

Therefore, Lei Tiantang set a small goal to build a spaceship that can sail in the solar system. With the development of science and technology, there will be no problem. Now the main reason that restricts human beings from building solar system spaceships is material problems. Without good materials, the thrust of rockets can not go up and the mass can not be increased There are too many dangers in space. All kinds of radiation and dust can threaten the safety of spacecraft.

If you want to build a spaceship that can take off directly from the earth, there are many things to do. Because human beings have never done such things, everything has to start from the beginning. However, Lei Tiantang is confident that he can solve the most critical material problems, and the rest is the design.

Of course, the design and construction is also a big project. Each system of the spacecraft has only limited experience to learn from. Almost all of them have to start from scratch. For example, the communication in the universe must now choose quantum communication, and quantum communication is still the most advanced science and technology in science. Huaxia is at the leading level in this field, but it is far away from the mature response on the spacecraft There is still a long way to go.

Another example is the life support system of the spaceship. Although there is an example of the international space station, the international space station is regularly replenished. If the spacecraft needed by Lei Tiantang needs to navigate in the solar system for a long time, the replenishment will be a big problem. Can't we launch the replenishment spacecraft often? So the sustainable life support system on the spacecraft is very important, and green plants can relieve the anxiety of astronauts who are in confined space for a long time.

There is also the engine of the spaceship. If a large-scale spaceship wants to take off from the earth, of course, it needs a powerful engine. There is almost no precedent for such an engine to learn from. Therefore, it must be designed and manufactured from the beginning, which will be a big project again.

There are control systems, escape systems and so on, almost all of which have to be designed from scratch. However, Lei Tiantang is not frightened by these problems. His life has already started. Now it is a good thing to have a goal for him to strive for. Otherwise, how to make money every day? He will not be short of money now. Regardless of the value of the precious metals such as gold he owns, let's say that he is now focusing on the development of new materials company. After the arrival of new laboratory equipment, he will open up and help develop some new materials. How much does it cost?

Of course, there's nothing wrong with having money. To build a spaceship, you need to spend astronomical amounts of money. But money alone is not enough. Sometimes it's useless to have more money. For example, Lei Tiantang plans to build a spaceship. Without the participation of the state, Lei Tiantang and his company can't do it.

Lei Tiantang considered this point when he thought about this small goal. Without the participation of the state, many things can't be done. The simplest point is that the top talents are almost the treasures of the country. If you want to design a spaceship, you must ask these babies to participate in the design. Otherwise, if you recruit some talents to train yourself to participate in the design, then the spaceship is still I don't know how long it takes to build it!

The key is that such a big project can only be done in a superpower like China, because it has the foundation of this industry, and there is no shortage of talents. If you want to build a spaceship in a country like India, you can't even build their own guns! That's why Tang Lei's country must support him.It is impossible for the state to agree to such a plan in the first place. It is estimated that the state will participate in the plan only in the middle and later stages. If an individual runs to the country and says that I want to build a spaceship, the country will take care of you. It's not good to have money. You have to prove that you can do this, and then go to the state for help. This is the way to do things. Otherwise, slogans are called out The sound of the sky is useless.

However, he still needs to keep in touch with the country in the early stage, and Lei Tiantang has also selected the target for the early contact. His company is going to carry out the research on new materials. After the laboratory equipment comes back, he plans to develop the first new material, which is the invisible coating used in high-end armaments such as stealth fighters. The current stealth coatings are basically the most popular If you use it a few times, you have to repaint it all day, like the F22 of Meidi.

There are several F22 in his storage space. There are ready-made invisible coatings on them for his reference. After he solves the problem that the invisible coatings are not durable, his company will also become a key military industrial cooperation unit of the state. In this way, he will develop new materials in the future, cooperate with the state gradually, and prepare the spaceship in advance It will be very convenient to seek cooperation with other countries.
