Compared with conventional internal combustion engines, the Stirling engine is obviously a bit unpopular. The principle it uses is to provide power through temperature differences, which means that it does not need to continuously release substances to the outside.
, for example, when using an internal combustion engine, exhaust gas will be continuously discharged to the outside, and when using a steam engine, steam will also be discharged.
When using a Stirling engine, only external heating is required, and the inside of the engine is a sealed environment, so there will be no gas leakage during this process.
Of course, this is of little significance to this world. If there are certain application prospects in space, there will be certain advantages in the absence of gas leakage.
In this world, people have chosen this technical route. The most important reason is that this technical route is the most suitable. People can indeed build internal combustion engines, but it is very wasteful to use them, especially
When hydrogen is used as fuel, even if the water produced by the fuel can be collected, the high-temperature water is wasted. Once the hydrogen condenses into water, the water will continue to lower its temperature and eventually freeze.
There is no way for people in this world to use ice water.
The energy wasted in the process of lowering the temperature of water is unforgivable to people in this world. Such a large amount of energy is wasted and this part of the energy cannot be applied. If it is only reflected in the form of water,
Maybe it doesn't feel too profound, but if the water belt is replaced by magma, it means that the huge energy from the liquid state to the complete cooling of the magma will be wasted, and there is no way to use it.
From this point, it is not difficult to see the huge waste caused here.
But if you choose to use a Stirling engine, you can first ignite it with hydrogen for heating. In a relatively closed environment, it is easy to collect condensed water, and the water itself has a very high temperature, and it is also
It can be used to heat the engine. After the heating is completed, the water will gradually cool down and even gradually solidify. But even the solidified water is quite hot in this world and can still provide heat to the engine until
The ice cubes can be thrown away after they are cooled down to a temperature that is not high enough for the engine to run at high speed. This is a great use of the heat in the water. Even if other fossil energy sources are discovered in this world, most of them will produce water after burning.
Yes, if this water is collected, the huge heat contained in it can also be used to drive machinery. In theory, the energy utilization efficiency can reach a very high level.
Although the cost of making this kind of thing is not low, with the production capacity of humans in this world, if it is produced underwater, it can already maintain a high output.
All metals can be softened underwater, which pushes the world's processing technology to a level that does not belong to them. The biggest industrial problem they face is actually creating materials that can exist stably in water.
The human body can live comfortably in it and make various metal materials like kneading mud. However, in order to ensure sufficient accuracy in making these materials, they need to have sufficient strength, and there is no way for this thing to cheat underwater.
That's it, if you want to use it as a tool underwater, you must be able to withstand the high temperature in the water without any softening. This means that even in water, there will be no reduction in the difficulty of processing these materials.
, and it is conceivable that it is difficult to create a higher temperature than water in water. It is almost impossible to use high temperature to soften these materials.
In other words, most of the materials produced in this environment are not ductile like metal, and most likely need to be cast in one piece and then finely polished before they can be used.
Therefore, most of the materials used in water are processed on the ground, that is, corresponding proportions of metal liquids or liquids of other materials are produced, and they are mixed for casting. After the casting is completed, they are cooled and then cast.
Sand the ground.
The reason for choosing the ground is that it is best to use solid molds for casting. All molds will soften underwater, making it difficult to perform precision casting. The grinding process is best to use metal manufacturing equipment and some specialized equipment.
Polished steel will also soften due to high temperature when placed under water. It can only remain hard on the ground and is suitable for polishing.
Although making materials that can be used underwater has a huge technical threshold for humans in this world, with their continuous development, they are assembled from parts one by one, and underwater machine tools are gradually born. Underwater can
If it remains hard, the difficulty of processing those soft metals will be greatly reduced. After the first engine was manufactured, the entire underground cave alliance celebrated for three days. This was a revolution for them.
The change in nature also means that they can explore more distant places. The limitation of exploring more distant places before was that liquid water cannot be stored in the outside world for a long time.
Even if hydrogen is made into a high-pressure cylinder that can be stored for a limited time, it will leak when storing hydrogen.
Of course, there are technological breakthroughs in this area, such as synthesizing organic matter, and then using water through the water produced during the combustion of these organic matter.
The simplest thing is to store methane. Although the molecules of this thing are not very large, they are not as easy to escape as hydrogen.
As related technologies continue to develop, the distance that humans can advance in the wild has also continued to increase. But there has been no revolutionary change, that is, the speed of advancement in the wild. Relying on humans to pull carts without large livestock,
The speed of progress is always limited. Although human physical strength and endurance are the best among most mammals, this endurance is ultimately limited and it is impossible to work continuously. Compared with most large herbivores,
The size and strength of animals and humans are not dominant, and they are not suitable for pulling carts.
This chapter is not over yet, please click on the next page to continue reading the exciting content! Now that there is a machine that can push the car forward by itself, the speed in the wild will be much faster. On the one hand, the machine
The power is greater than that of people, and the speed of progress can be faster. On the other hand, machines do not need as long a rest as humans to recover their physical strength. In the case of large-scale mass production, they can also save labor. Saving labor means traveling
You can free up more space to carry resources. If you want to travel far, you can carry more food and water. You only need to separate part of it to carry fuel, and the part that carries fuel can be fixed.
to a certain extent instead of water.
During this time, the underground alliance has also continued to expand. Human beings are indeed quite fragile, but as a species they are also quite tenacious. There are humans in all major underground caves, so after their exploration capabilities become stronger, they move towards
You can find it by exploring further afield. There are more caves underground. You can open roads through the caves on the edge of the original territory to connect to these new caves, establishing a huge survival network underground.
However, due to the development of industry, the development speed of these remote areas that have just been connected to the network is obviously slower. To maintain the rapid development of industry, a large number of people must be concentrated in cities.
This also means that the development of remote areas will always be half a beat slower. Fortunately, there is no need to worry about the growth of the world's population. It is normal for a family to have five, six, or six children. As humans gradually
After breaking away from the primitive tribes, these new children also began to receive education. Human beings in this area are still very weak in instilling the hierarchical concept of the feudal system. The reason is also very simple, conditions do not allow it.
On the one hand, the natural environment is too harsh. Human beings in this era have habitually chosen to stick together. Compared with the feudal era, there is enough productivity to allow a man to be more united when he feeds his family.
Because if you don’t unite, you will freeze to death in this era. The existence of this primitive collective inhibition makes it easy for the tribe to concentrate on doing big things. Because everyone is used to this model.
In turn, technological progress and productivity progress are forcing changes in production relations. The fact that a large number of people who understand technology are needed makes it necessary for people to develop everyone's subjective initiative, especially in recent years.
Towards the birth of brand-new technology, let people realize the importance of groundbreaking thinking.
Today's human beings are far from getting rid of the existential crisis caused by the harsh natural environment. Although some people want to occupy more resources and become kings in this era. But if they really want to do this, workers will lose their enthusiasm for production.
It is very likely that the productivity in this cave will drop significantly, so that it will eventually return to the original primitive era. Even the rulers do not want the era to return to that barbaric period, so things such as internal fighting and the oppression of the bottom
.It is constantly being pushed back. When productivity has developed, it will be difficult to go back to the original era when the emperor could decide everything.
They can only be forced to move forward. As the underground network gradually communicates and underground passages are gradually established, a new generation of people grows up in education and becomes better workers and developers. The national power of this underground kingdom finally no longer worries
, the country may be completely wiped out by natural disasters at any time, and the scope of their exploration has finally expanded to hundreds of miles, and now they have the ability to build roads on the surface.
But the road they built on the surface finally led to the destination that surprised everyone.
It was the largest exploration team in history. They came to the ground from the edge of the cave and headed east. Their purpose was to go to the end of the legendary world and explore what was there? They carried the most fuel and wanted to
Explore to the furthest reaches.
However, after they advanced hundreds of kilometers, the sight in front of them shocked them greatly.
It was an endless plain, or to be precise, it should be an endless stretch of ice.
People in this world are familiar with ice, but in their impression ice is covered under snow most of the time. It is rare to see such extremely vast ice fields. There is almost no snow on the ice fields.
The snow covers the ice and will soon be blown away by the wind, while the ice beneath your feet gives people an extremely terrifying feeling.
Because they are too deep, when you look down you will see darkness. It is an extremely dark environment, as if you are staring into the abyss.
In fact, it is quite pure water. After this water freezes, it is still extremely transparent. Although you cannot see the bottom of the water, you can still see hundreds of meters deep. This is the ocean on this planet, but
It is a frozen ocean. The sea surface is frozen into an extremely flat ice surface. Because it is so flat and smooth, there is no snow on the surface. A gust of wind will blow away all the snowflakes that have fallen on it.
And standing on such an ice surface and looking down brings tremendous psychological pressure to people. The bottomless abyss seems to be able to swallow everything. Just standing on this layer of ice requires a lot of effort.
Strong psychological quality.
In fact, there is no need to worry about falling. The exploration team carried some metal equipment to carry out drilling work here, and they dug a cave tens of meters deep. They were far from penetrating this layer.
Ice, such thick ice. It may even be ice that extends all the way to the bottom of the ocean. There is almost no need to worry about them breaking and letting people fall in.
It was also hard for them to imagine that a piece of ice would freeze. It was so crystal clear, with almost no gas mixed inside, that it was so chilling to look down at the depth below.
The exploration team, with some extra fuel, dropped markers along the way and also tried to drill underneath here to see how thick the ice was.
The most important thing is that they want to see if there is liquid water under the ice. For humans in this world, liquid water is the most precious thing, because it can help humans in this world avoid most temperatures.
Damage is also an indispensable resource in industrial production. If there is liquid water under this endless ice sheet, it will be unparalleled good news for the future development of human beings today.
The work of drilling is extremely boring, breaking through the ground layer by layer and exploring downward layer by layer.
Everyone felt that maybe they were thinking too much. All the water on the ground had solidified into ice. Even though this was a vast sea, the depth of the ice here seemed to be invisible at all. Maybe it was all ice below.
There is no water at all.
But as the drill suddenly lost its support and fell downwards, everyone involuntarily concentrated their attention.
