Douluo See You For a Long Time

This can be regarded as a unique phenomenon unique to this universe. The energy required to electrolyze water in this universe is much higher than in other worlds. If you want to electrolyze water, the energy barrier you have to break through is quite high, and this energy is naturally stored in the gas after the water is decomposed.

This is an important reason why direct current was developed here. Compared with alternating current, the biggest advantage of direct current is that it can separate hydrogen and oxygen when electrolyzing water.

In this way, hydrogen can be stored separately, with a much lower mass than its storage capacity. You only need to carry this hydrogen when you go out. In this process, the low temperature and temporary heat will not ignite these gases when water is needed, and water can be obtained. And obtaining liquid water means that when traveling long distances, you don’t need to worry about the liquid water you carry solidifying during the trip, making it impossible to continue moving forward.

The only problem is that hydrogen is difficult to store for a long time. It seems that it is a gas and can be stored. Other gases should also be able to store it. But in fact, because the molecules of this thing are too small, in most cases The container will penetrate through the gaps between molecules, so don't think about playing with the hydrogen balloons you buy on the street for many days after you take them home. In a few days, the balloon will no longer be able to remain suspended in the air because the gas inside will leak out from the gaps.

But compared to the time it takes for liquid water to freeze in the cold outside environment, the time that hydrogen can be stored is already long enough. With such a long time of storage, it is enough for a team traveling far away to obtain enough liquid water. Supplied.

More importantly, if you simply carry hydrogen, one advantage is that the quality will be very low during the carrying process.

This is a very simple reason. The proportion of mass occupied by hydrogen in water is very small. Even if it is carried in a container that can withstand high pressure, the extra mass required is less than that of carrying liquid water directly. too much.

Relying on this method, you can carry more water with less space and less mass.

After all, there are no big livestock in this world. Cars have to be pushed and pulled by people. The animal power that can be used is limited, which also makes the mass that the car can carry become limited.

In this case, the role that the car can play. This means that every bit of space and every bit of quality that can be carried must be carefully utilized.

As for the bottle filled with hydrogen, it is relatively easy to get. People in this world have unique advantages in metal processing. If you want to process such a seamless steel bottle in water, it is as difficult as blowing a glass bottle. You can directly make a bottle like kneading dough, and then Then blow it up a little bit. In this way, there is basically no need to consider the problem of gaps. If there are no problems in the alloy manufacturing, the strength can be guaranteed.

If such a cylinder were produced in other relatively primitive civilizations, the production cost might be astronomical, but here, it is really not a precious thing.

After many attempts in the materials science laboratory, we have found several bottles that can relatively effectively isolate hydrogen leakage. The rest is to find a way to pressurize the bottle so that it can carry more gas. In this regard, they chose a structure similar to a pump. Anyway, the structural strength of the bottle is guaranteed, and it is stronger than that of one-piece casting. High, in this case, as long as there is enough power to pump air inside, you can pump as much as you can. Theoretically, you can create a liquid environment inside, and the precision of the metal they can process is also very good. With some relatively soft materials, an extremely airtight cylinder can be made to complete this inflation work.

For this era, driving a car to travel far away is a very dangerous thing, especially exploring unknown areas, which requires unparalleled courage.

Therefore, the king of this country can have a considerable degree of tolerance for the costs incurred by explorers, and can pay extremely high costs to allow the exploration team to explore.

In the process, they are also thinking about how to improve the power of these cars so that they can travel farther. For a long time, the only way to travel long distances was to rely on people pulling carts, and the limitations were too great.

Because the productivity of development was too fast, it did not enter the slave age. Otherwise, it is actually possible to pull the car to a certain extent with effort. To solve the current problem. However, efficiency still needs to be improved.

And people in this world have begun to think about how to make something like an engine in a car to drive the car forward.

Someone tried to make pedals like a bicycle and use them on the car. This method has a certain effect. It saves effort when riding on flat ground. Just like riding a bicycle, the driver can sit in the car with several people, which makes it faster and easier.

But this method can only be used on flat ground. If the ground is uneven or uphill, this method will be more tiring than pulling the car directly.

But this is at least a big improvement. At least on downhill or flat ground, it can save a lot of manpower and speed up the process to a great extent.

With the invention of four-wheeled bicycles, some people also began to try two-wheeled bicycles. The biggest difficulty in producing bicycles with the current production capacity may be the chain, and the amount of engineering in this area has become widespread as stamping technology has begun to spread on a large scale. , the difficulty has become the easiest part, which is just the car's tires, which is still relatively difficult to deal with now.

After all, there are no rubber trees in the tropics in this world. Synthetic rubber also requires petroleum and other things to make it. So far, it can only be woven into tires using the fur of some animals or the fibers of plants, which has certain performance in terms of shock absorption. The shortcomings are that it is a bit tiring to ride.

But this is already a pretty good means of transportation. With this new means of transportation, at least traveling between different caves becomes easier.

Several kilometers of roads have been built between the different caves. These roads could only be passed by walking. Even if there is a car pulling the car, it will not be faster than walking. So much so that it takes a long time to travel between different caves. As a result, the circulation of materials and personnel has become difficult. A cave person can basically only work in his own cave. If you want to work in other caves and concentrate the labor force, commuting time will become quite troublesome.

But with the birth of the car, the distance of a few kilometers no longer counts. The roads between caves are not formed by flowing water or wind in nature, but are built by humans. Depending on the factors, these roads are quite smooth.

On such a road, riding a bicycle-like thing through different caves, even the longest cave that is nearly ten kilometers away can be crossed in two or three hours.

Even if you ride faster, you can further shorten the time. This change does not seem revolutionary, but it has a very significant effect, that is, it allows people in different caves to gather in the same cave, and the labor force is gathered together and dispersed in various places. The difference is huge. If you can gather a large number of people to carry out concentrated work, you can build some relatively grand projects.

Industrialization itself requires the concentration of large amounts of labor in cities. This time, after having the ability to concentrate labor, the expansion of the cave began. Compared with the water conservancy projects of people who normally live on the surface, the projects carried out by people in this world should be called thermal power projects.

That is to say, the magma is guided to various parts of the cave through pipes to create a geothermal-like effect. Make the temperature in most areas of the cave suitable for survival.

In addition, the stone walls around the cave are excavated. After excavating these areas, more living space can be obtained. By building new magma rivers in these living spaces, you can maintain a relatively comfortable environment in this space.

As for this underground world, a large amount of water has been transported. Magma flows through underground pipes, and above the magma pipes is a groove. These grooves are filled with flowing water. This water acts as The medium of heat conduction can allow a small amount of water vapor to exist in the cave, and the existence of water vapor can resist the harm of high temperature to the human body.

Simply approaching the area along the river. If you get too close, the high temperature will burn your skin. But if you pour a basin of water into the magma, the water will not boil in the high-temperature magma. But it will evaporate slowly. When the water vapor content in the high-temperature gas is high enough, the damage to the human body will be greatly reduced, and you will not be burned by the magma at a relatively comfortable temperature.

Human beings in this world have figured out how to transform the world's environment to suit their own survival.

Water is almost a universal balm. Human beings in this world in the future will probably be more accustomed to living in a humid environment, with water vapor everywhere.

The central cave was enlarged to five times its original size in the process. And a larger factory has been built in this area that is most suitable for human survival. At the same time, on one side of the cave is a mine next to it.

Because they live in underground caves, mining is basically an innate skill for them. The mineral resources of this planet are also relatively abundant. In the process of continuous communication from cave to cave, they can Various mineral veins are found underground. This is also an important reason why they did not lack any metal during the construction process.

In addition to this, another major project is to transport the ice and snow from the outside into the cave in a systematic manner. This can really be regarded as a water conservancy project, but in the end, ice cubes have to be dug from the outside.

The only difference from before is that when you go downstairs from the outside, you can pile ice blocks directly along the slide and slide from the surface to the cave. Because it is downhill all the way, even if you don't need a car to transport it, you can rely on the ice blocks. With a relatively smooth surface, you can easily reach your destination, and then in a huge pool heated by magma, to be precise, a high-temperature-resistant super iron pot, the ice will melt into water and turn into a temperature that is warm to people. Suitable water flows to all parts of this cave, maintaining an environment suitable for human survival.

For humans in this world, the most comfortable thing is probably to take a bath in warm water heated by magma after a busy day at home. Only when the whole body is soaked in water can humans feel that they truly belong to themselves. comfortable temperature.

As industrial capabilities have increased, research and development capabilities have also been further enhanced. After reaping the benefits of transportation, they are even more motivated to try to develop vehicles that can walk on their own.

It's just that in this world, there is no hope for steam engines. Find the book www.zhaoshuyuan.com. And humans in this world have taken two technical directions at the same time, one is the technical direction of internal combustion engines. One is the technical direction of the Stirling engine.

Both directions are technologies that can be realized in this special world. First of all, let’s talk about the direction of internal combustion engines. To be precise, it should not be internal combustion engines, but machines that use natural gas.

Promoting rotation through the reciprocating motion of the cylinder has been basically recognized as an effective power conversion method. It's just that fossil fuels like petroleum have not yet been discovered, so hydrogen is used to provide energy.

In fact, people in this world want to use electric motors to power their cars. They have also manufactured electric motors. The problem is that having electric motors does not mean they have batteries with sufficient capacity. Batteries are nothing even in the 21st century on earth. It is a very troublesome problem that has not been effectively solved. After all, this thing itself is quite difficult to make. The industry in this world has just begun to develop. How can it be possible to manufacture portable and high-energy batteries.

So you can only take off your pants and fart, first use electrolysis of water to obtain hydrogen, and then use this gas as fuel. Of course, some people also try to use methane as fuel. If it is through fermentation, this gas can also be obtained to a certain extent. Yes, you have no doubt that fuel is a pretty expensive thing in this world.

In comparison, the Stirling engine is much more practical for the residents of this world. This is a machine that can work as long as it provides a heat source and a temperature difference, and this world is very rich in magma resources. What's more important is that liquid water itself has a huge temperature difference with the outside world and can be used as an energy source for this kind of engine.
