Douluo See You For a Long Time

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 closed environment. 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 make internal combustion engines, but it is very wasteful to use, 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 finally freeze. There is no way for people in this world to use ice water.

The energy is wasted in this process as the temperature of the water decreases. It is unforgivable for people in this world to waste such a large amount of energy without being able to apply this part of the energy. If it is only reflected in the form of water, it may not be too profound, but if it is Replacing the water belt with magma 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 can be regarded as 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 processing technology of this world to a level that does not belong to them. The biggest industrial problem they face is actually to create materials that can exist stably in water, so that the human body can survive comfortably in water, and to make various metal materials like kneading mud, but when making these materials, they want to ensure that Sufficient accuracy requires them to have sufficient strength, and there is no way for this thing to cheat underwater. If it wants to be used as a tool underwater, it must be able to withstand the high temperature in the water without any softening. This This means that even in water, there will be no reduction in the difficulty of processing these materials. It is conceivable that it is difficult to create a higher temperature than water in water. Using high temperature to soften these materials is almost impossible.

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. It is also best to use the polishing process. Metal-made equipment and some steel materials specially used for polishing will also soften due to high temperature when placed underwater. They can only remain hard on the ground and are suitable for polishing.

Although making materials that can be used underwater has a huge technical threshold for humans in this world, as they continue to develop, they are assembled from parts one by one, and underwater machine tools are gradually born. If it can remain hard underwater, the difficulty of processing those soft metals will be greatly reduced. After the first engine was manufactured, people in the entire underground cave alliance celebrated for three days. This was very important to them. Said to be a revolutionary change, it 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 is to store methane. Although the molecules of this thing are not very big, they are not as easy to escape as hydrogen gas.

As related technologies continue to develop, the distance humans can travel in the wild is also increasing. But there has been nothing revolutionary about the speed of progress 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 limited after all. Possible Continuous Work Compared with most large herbivores, humans are not advantageous in size and strength and are not suitable for pulling carts.

But now that there is a machine that can push the car forward on its own, the forward speed in the wild will be much faster. On the one hand, the power of the machine is greater than that of people, and the forward speed can be faster. On the other hand, machines do not require humans to rest as long as humans do to recover their physical strength. In the case of large-scale mass production, they can also save labor. Saving labor means that more space can be freed up to carry resources during the journey. If you want to If you want to travel a long distance, you can carry more food and water, and only part of it needs to be divided to carry fuel, and the part carrying fuel can also replace water to a certain extent.

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. Roads can be opened 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. Five, six, or six or seven children in a family are very normal. As humans gradually break away from primitive tribes, these new children also begin to receive education. For feudal society, Human beings in this area are still very weak due to the instillation of institutional hierarchical concepts. The reason is also very simple, the conditions do not allow it.

On the one hand, the natural environment is too harsh. Let humans in this era habitually choose to stick together. Compared with the feudal era, there is enough productivity that a man can be more united when supporting 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 tribes to concentrate their efforts on 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 dominate in this era. But if this is really done, the workers who have lost their enthusiasm for production are likely to cause the productivity in this cave to drop significantly, so that it will eventually return to the original primitive era. And even the rulers don't want the era to return to that barbaric period, so there are things like internal fighting and the oppression of the bottom. It keeps 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 destroyed by natural disasters at any time. 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 carry the most fuel and want to explore the furthest places.

However, after they advanced hundreds of kilometers, the sight before them shocked them.

It was an endless plain, 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 mostly covered with snow. A small amount of snow covers the ice surface and will soon be blown away by the wind. The ice principle gives people an extremely terrifying feeling.

Because they are too deep, when you look down, you 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 fall on it.

And standing on such ice and looking down, look for Shuyuan www. zhaoshuyuan.com The psychological pressure brought to people is extremely huge. The bottomless abyss seems to be able to swallow everything. Just standing on this layer of ice requires strong psychological quality.

In fact, there is no need to worry about falling at all. The exploration team carried some metal equipment to drill here, and they dug a cave tens of meters deep. They are far from penetrating this layer of ice, such a thick ice surface. It could even be ice that spreads all the way to the very bottom of the ocean, with little need to worry about them breaking and letting people fall in.

It was 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 the precious things in this ice layer, because it can help humans in this world avoid most temperature damage, and it is also an indispensable resource in industrial production. If there is liquid water under this endless ice sheet, it would 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.

But as the drill suddenly lost its support and fell downwards, everyone involuntarily concentrated their attention.
