Chapter 353, Xinghai Agricultural Technology Group
The size of space battleships and spaceships is also an important indicator to measure the level of scientific and technological development of a civilization.
This does not mean that you can build it as big or small as you want. Just like shipbuilding, the larger the ship, the higher the technical content. Especially for warships used in war, there are many factors to consider.
Apart from anything else, speed alone is very critical.
Battleships at sea are basically living targets if they are not fast enough. Under the rapid attack of fighter planes and missiles, a slow speed means waiting for death. No matter how good the ship defense is, there will always be flaws, let alone
The speed is too slow, making it difficult to rush or escape.
This is especially true in the interstellar universe. Speed is life and time, and determines everything.
In interstellar wars in the universe, the attack speed of weapons is basically the speed of light, or even super-light speed. If your warship is only built to be large but does not have enough speed and flexibility, it will be easily destroyed by others as a living target.
To be able to confidently build a battleship large enough must have mastered powerful power technology, which can provide strong enough power for a huge space battleship, allowing it to have sufficient speed and flexibility, as well as strong energy protection.
Medium-sized spaceships and space battleships are nothing. What is truly huge are large space battleships, which are generally more than 10 kilometers in length and several kilometers in width and height.
This type of space battleship and spaceship is truly a behemoth, like a small planet.
A civilization that can build such large spaceships and space battleships is at least a star field level civilization. It spans huge star fields and is the overlord of a vast star field.
Of course, when cosmic civilization continues to develop and technology reaches a higher level, the size of spaceships begins to continue to develop smaller, especially when they start to touch space technology and master space storage technology.
Spaceships and space battleships began to get smaller and smaller again.
Small does not mean weak. In fact, when cosmic civilization develops to the stage of advanced civilization, the smaller the spaceship is, the more powerful its technology will be.
Often advanced cosmic civilizations dispatch a few seemingly miniature space battleships to easily destroy those seemingly huge and numerous space battleships.
The whole process develops from small to large, and then from large to small, returning to basics. This is what it means. However, this process is extremely long, involves countless high-tech technologies, and can also represent a powerful universe.
The path civilization takes.
Liu Yuan is very clear about these, because with the guidance of the inheritance seeds, what he has to do now is to develop from small to large and create a bigger and stronger spaceship.
"Boss, if we want to manufacture medium and large spacecrafts in space, we need to build steel plants in space so that we can directly manufacture and cast medium and large parts in space."
Tang Peng is in charge of Xinghai Aerospace and has the most say in this matter. Although he is very excited when he thinks of building a medium to large spacecraft, there are also many problems that need to be solved.
The larger the spacecraft is built, the larger the parts required.
Many people may say that large parts can be spliced together. What's so difficult? It's more difficult to make them smaller, such as chips, and nano-level processes are more difficult.
But in fact, it is not easy to go to a big city.
Splicing can indeed solve some problems, but it will involve a very important thing, the issue of strength and toughness.
There is a huge difference between large spliced parts and parts formed by integral casting. Their strength, toughness, load-bearing capacity and many other aspects are incomparable.
Especially when it comes to engines, the use of controllable nuclear fusion technology to provide power and energy, as well as warp speed flight, will place very high demands on the ship. It is simply impossible to use splicing to build medium and large spacecraft.
Tang Peng participated in the manufacturing of the space carrier, and Xinghai Technology itself has built many aircraft as large as the space carrier, and is very aware of this.
If we were to build a larger spaceship, we would definitely not be able to do it with the current technology.
Moreover, medium and large spaceships cannot be manufactured on planets, because even powerful anti-gravity technology cannot guarantee that such a massive spaceship will not have problems during takeoff and landing.
The gravitational pull of the planet is very huge.
It may not be noticeable when the mass is small, but when the mass reaches a certain level, the planet's gravity becomes very important and is something worthy of attention.
The manufacturing of medium and large spaceships must be done in space, and medium and large spaceships do not need to take off and land on the planet. They will always be parked in space, loading and unloading cargo, etc., relying on small,
It can be realized with a miniature spaceship.
"Whatever supporting facilities are needed, we will do it from beginning to end and explore slowly, because what we are doing now is unprecedented, and we are creating a new history and chapter."
Liu Yuan nodded and said.
When a space factory should be built, a space factory should be built. A space steel plant must also be built, which is related to another space mining industry.
The iron ore for the space steel factory is definitely not transported from the earth or the moon. It usually needs to mine asteroids and directly smelt asteroids to obtain a large amount of steel raw materials.
When everyone heard the order, they nodded.
The reason why every employee of Xinghai Technology is proud is not only because the salary package provided by Xinghai Technology is good enough so that everyone can live a dignified life, but also because Xinghai Technology is a real technology company and has researched many
Technology is at the forefront of human technology.
Biotechnology, electronic technology, virtual technology, aerospace technology and many other fields are all at the forefront of the world. What we play is high technology, and our dreams are the stars and the sea. How can we not be proud of such a big deal?
"The third thing is that I am going to set up a subsidiary group company called Xinghai Agricultural Technology Group."
After talking about building spaceships, Liu Yuan talked about developing agriculture.
"ah?"
When everyone heard this, they were immediately shocked. They all looked at Liu Yuan in disbelief.
"Boss, let's go do some farming?"
Xie Xin was a little dumbfounded and asked quickly.
He himself was born in a rural area and knows very well what agriculture is like.
Nowadays, one acre of land can produce about 1,000 kilograms of rice, and one kilogram of rice can be sold for about 1,22 yuan, which is even 1,300 yuan.
This rice seed costs 100, arable land 100, chemical fertilizer 100, and pesticide 100. The cost is almost 400. After all, it seems that you can still earn 900.
However, farming requires a lot of labor, including plowing, weeding, transplanting, spraying pesticides, harvesting, fertilizing, draining, harvesting, etc. It takes at least 20 days to plant a crop of rice.
Even if calculated based on the minimum wage, which is 40 yuan a day, it will be 800 yuan in these 20 days. In the end, the net income from one acre of land is only 100 yuan. Just plant a ball.
This is still based on ordinary people's calculations. If Xinghai Technology is engaged in agriculture, it will definitely be a loss to grandma's family.
Everyone knows how expensive the company's labor costs are. Any employee earns millions every year. If you are still farming, even if you are engaged in pesticides, fertilizers, seeds, etc., you will probably lose a lot of money.
So everyone doesn’t understand why Liu Yuan is engaged in agriculture. Is it because he has too much money and no place to spend it, or does he think there are any prospects for agriculture and what can he do in space?
"Yes, this kind of agriculture is like scraping the flesh off a mosquito's legs. We will definitely lose money. Even if we develop agriculture in space, no matter how much technology we use, we will still lose money."
Lu Yong also followed suit.
It’s true that Xinghai Technology has money, but you can’t spend it indiscriminately, right? If you have a big family and a big business, you still have to save money. You still have to save the money you should save, and you can’t build it randomly, otherwise even if it’s gold and silver, it will be lost.
It’s gone.
In everyone's opinion, agriculture is definitely a loss-making business and field. Xinghai Technology will definitely lose money when entering this field, and it will be a blood loss.
Even if agriculture is developed in space, the output and quality may be higher and better than on earth, and the price may be more expensive, but the benefits are still not commensurate with the input and cost.
Agriculture is not of much importance or value when there is food to eat. The time when it is most valuable is during times of famine.
However, with modern technology, the restrictions and impact of natural conditions on agriculture are getting smaller and smaller, and food can be bought and sold on a global scale, so the impact is even smaller.
Therefore, the possibility of global food famine is obviously relatively small. Even if the price of food rises several times, there will not be much profit. What's more, there are many places to grow food in the world. This transaction of Xinghai Technology is not
It's a way to do exclusive business.
"The purpose of developing space agriculture is not to make money, but to research agricultural-related technologies and reserve related talents and resources."
"Although agriculture is inconspicuous, it is of great importance and the technical content is actually quite high. Developing agriculture in space has huge advantages. It can get rid of the restrictions and influences of natural conditions. It is also a trend in the development of interstellar agriculture."
"What's more, in the future we will move towards the interstellar universe. If one day we immigrate to alien planets, of course we will start to grow food in space battles."
Liu Yuan looked at the astonished expressions of everyone and said with a smile: "Of course, this can be considered a kind of welfare. We develop our own space agriculture and grow our own food and vegetables. We know what we are doing and can eat with more peace of mind.
Don’t worry, there are too many genetically modified things now.”
Hearing Liu Yuan's words, everyone immediately nodded, this benefit is okay.
PS: Do you think genetically modified things are safe?
