The special ecological environment of this world has also allowed the development of special technology trees here, such as trains that are driven by the heat of magma. The construction method is quite strange. The train tracks are built above the magma river.
Even during a considerable distance of the train's advance, it is advancing on the top of the magma. The heat-absorbing grid of the engine is placed on the chassis of the vehicle. When passing over the magma, it does not require any external power.
Can advance automatically.
This completely separates railways and highways into two systems.
The highway system should avoid underground magma rivers as much as possible. This can ensure the safety and smoothness of the road and prevent it from being suddenly enveloped by the gush of magma while driving.
However, the railway system must guide the flow of the magma river and travel above the river along the magma river. Most of the railways are made of high-temperature-resistant materials. The closer they are to the surface of the magma river, the more efficiently they use the heat energy below.
The higher it is, and this means that the trains do not need to carry too much fuel most of the time. They only need to absorb some magma at the parked station to keep these trains running.
On a certain level, this thing can still be called a train. After all, it really travels by burning fire. Not only that, it also travels on flames and magma.
Because of the harsh environment inside this kind of vehicle, there are basically only people in the front of the vehicle, and it is not used to carry passengers, but to transport various industrial materials.
With the construction of these railways, various ores and finished materials needed in industry can be transported to various places at high speed.
It is also quite energy-saving and cost-saving. A single transportation hardly consumes any additional energy to deliver the transported items to the place.
This is an unimaginable environment on earth. Of course, it is also unimaginable on earth that the weather here is so cold and freezing, but the temperature difference has a great impact on human beings.
The roar of the train connects the underground caves together. With the emergence of these subways, a small number of subways far away from the magma are also being constructed as underground public transportation networks, which can further expand the scale of the city.
Let more people live and work in the same cave. The more people an industrial system can accommodate, and if these people can be used to their best advantage, the faster the industrial progress can be promoted.
It's just that now the location of concentrated population is gradually shifting. Road construction is gradually moving towards the ocean. Industrial centers on land can only become secondary industrial centers in the end. With the discovery of the ocean, the ocean will
It has become a real industrial focus. In seawater, humans can maintain a comfortable life for a long time. The temperature will make people feel extremely comfortable.
At the same time, in this environment, various processing industries are also very easy to carry out.
What needs to be considered when processing underwater is not how to soften the metal, but how to make the softened metal hard after mixing.
At this time, you can't just consider metal materials. Not all metal materials can withstand high temperatures. At such high temperatures, sometimes the alloy must be doped with some non-metallic substances.
The physical conditions of this world are so strange. Human beings are not yet capable of building cities underwater, but they have determined their own development direction. Human beings in this world will develop in the direction of aquatic life.
As they get out of the trough under the on-demand broadcast, human beings in this world have gradually begun to move towards their own prosperity. When their IQ is not suppressed, human beings are actually a very tenacious species. Even in extremely harsh natural environments, without any
Despite the interference of thousands of people in the wild, you can still find your own way of survival bit by bit in the complex and peculiar natural environment.
As the population gradually increases, human industrial technology in this world also begins to continue to develop and become more and more advanced.
People have also begun to develop in directions other than basic necessities of food, clothing, housing and transportation. In addition to basic survival needs such as food, clothing, housing and transportation, people also need more convenient access to knowledge. In the past, the knowledge of this world was recorded on fiber-like materials like paper.
.
But this kind of thing is too inconvenient after all, especially in underground environment or water.
Needless to say, if paper made from this fiber is placed in water, it will be soaked immediately like a puddle of mud.
In particular, the water temperature in this world is still very high. Even plant fibers can withstand this high temperature to a certain extent and can adapt to this high temperature like the human body. It is definitely not suitable for use in water.
In addition, if it is used in a relatively dry place in a cave, it must be stored in a place that is quite cold for humans. Because only in places that are quite cold for humans, the temperature can be reduced to below 50 degrees, which is equivalent to this world.
If these papers are stored in a warm and fresh place, they will burn uncontrollably.
When people are close to Lianjiang, they will feel dryness on their skin, and the same is true for these papers. If you want to preserve them for a long time, you need to wet them with water. After soaking them with water, let them freeze one by one in a relatively cold environment. Freeze
Store in ice cubes.
After freezing, the possibility of damage to the paper is greatly reduced. Even if it is placed near magma, at most the water that froze the paper will slowly melt. It will not directly burn the paper.
But there is also a problem, that is, during such freezing, one of the flexible characteristics of paper is lost.
In such an environment, the paper becomes cardboard that is difficult to fold. If it is folded with force, it is likely to break into two sections.
In addition, another problem is that after freezing, the surface of the paper is as smooth as ice, and there is no fiber to absorb ink. In this case, writing on the paper is no longer possible.
.
Relatively speaking, in such a harsh environment, you need to first write down what you want to record on paper, and then completely freeze and seal it.
Books in this world are not bound. Instead, the leaves to be read are put in a box, like playing cards. When you need to read, the contents are pulled out. There are. A small number of books are and
They are bound together like normal books. However, their binding method is not to glue one side together. These frozen papers are almost inelastic. Their binding method is to punch holes in the paper and then use spring-like binding methods.
Connect them in series, so that the page turning effect can be achieved. When turning the pages of this kind of book, although the order will not be disrupted because of forgetting the order of each item, it will still face some problems, such as
If you apply too much force, the joints will easily break. This is the problem with paper that has lost its flexibility.
And even if this thing has been improved in this way, it cannot be used underwater. People in this world have also begun to explore in the field of chemical industry. Because the various characteristics of water have become unique, their chemical industry
The road is also very strange.
Plastic is very difficult to make because there is no petroleum, but they extracted similar chemicals from the inside of a certain plant they grew. Because it contains crystal water inside, it has certain high-temperature resistance.
, some properties close to plastic make it more suitable for recording than ordinary paper, and its high temperature resistance makes it not easy to burn. It can be easily stored even if it does not touch water. It is just a little troublesome to write, but there is no
Due to the nature of the fiber, the things written on it can only float on the surface, and can only be written on it with something similar to a marker.
But anyway, it is difficult to write on paper with fiber even under water. If you want to write on plastic-like paper without fiber, you must also use high-concentration pigments, or you must find a completely new way.
It is also possible to leave traces on such materials in a similar way to engraving. When making these papers, the manufacturers have already considered the possibility of using them underwater. When underwater, all
Pens will leak ink, even if they are made into special ballpoint pens, they will still face similar problems.
So what should we do if we want to solve this problem? Just give up the ink in the pen and make fuss on the paper instead.
If you carve words on a piece of white paper, even if you don't consider the possibility that the paper will be missed, it will be quite difficult to distinguish the words engraved on it. Carving words on a stone slab can be easily distinguished because the unevenness of the stone slab is relatively small.
Obviously. As long as you look at it slightly from the side, you can easily distinguish the uneven marks on it. Naturally, it is relatively easy to identify what is written on it.
But if you look at it from another angle, if there can be obvious optical phenomena after engraving on paper, then writing on paper through engraving will become one of the feasible solutions. The original engineer thought that it should be made
A material that changes color under pressure or that may change color when cut.
After developing this idea for a long time, they discovered that this idea was not feasible. It was almost impossible to create brand new compounds simply relying on this pressure, or even to synthesize new elements for labeling in this way.
.
Technology in this area theoretically exists, but existing civilization cannot develop it. The temporary technology that replaces this area of technology is actually quite simple. It only takes a little thinking to solve this problem, which may require a lot of effort.
Problems that can only be solved by technology.
The solution given by engineers in this world is to replace ordinary paper with two or three layers of paper.
It means that the outside of the paper is normal white, but the inside of the paper is black or other colors. Then put the two papers together opposite each other, so that only the white side is exposed.
In this way, when using these papers, you only need to scratch the paper through engraving, and you can see the white paper, leaving dark writing on the paper.
In this way, you can leave what you want to write on the paper. The technical difficulty of doing this is obviously much simpler than changing the color of the paper surface by compressing the paper surface and maintaining it continuously.
It can be seen from this that humans in this world are not lacking in creativity at all. Although this brand-new material is difficult to apply paint on, as long as the two sheets are put together, it is actually a perfect writing material.
Even the back can be written. However, this will cause some topological problems during the writing process. If there are equally vacant positions inside some words, writing on them may cause the paper in the vacant positions in the middle to fall off.
What needs to be tested is the adhesive. It must be strong enough when the two pieces of paper are stuck together. It will not break even if it is wet.
Okay, now that we’ve got it figured out, it’s much easier to write underwater. The current plastic-like paper doesn’t have much of a problem when it comes to writing. It’s easy to scratch the surface of the paper. On the paper
After leaving traces, it is not so easy to be damaged. However, compared to traditional paper, the information stored in this way is still more susceptible to damage.
And people in this world are not limited to storing information through paper. They want more efficient information storage equipment. And through the invention of this new paper, they are thinking about whether information can be stored on paper tape?
The characters they use are still hieroglyphics. Therefore, writing on paper takes up a lot of space. It is also inconvenient for mechanical equipment to read what is written on it.
But on the other hand, if the text is converted into another form, such as a binary form, the space occupied by a text should be compressed smaller, and it will be easier to convert the text under special circumstances.
Write it successfully.
So their development direction began to develop in the direction of magnetic tape. Magnets must exist in this world, after all, they made the earliest generators that way.
But it is often not suitable to use it underwater. Current generators are rarely used underwater. On the one hand, there is leakage, and on the other hand, the relative temperature of water in this world is very high. And
Demagnetization often occurs at high temperatures. If you want to make magnets or tapes out of conventional particulate matter, you need to consider whether demagnetization will occur due to high temperatures when used underwater.
As a result, tapes in this world have taken some different paths in the process of development. They are also carriers for storing information. They do not necessarily need to be magnetic. In theory, as long as the material can leave traces, it can be used to store information.
The use of media and materials with a certain degree of magnetism only makes the process of reading and writing easier.
