With wood products and ceramic products, the next thing the commissar will visit is the micrometallurgical factory, an important factory for the third material.

The metallurgical industry has been an industry with high temperature and high energy consumption since ancient times. Steel does not melt into a liquid state until it is more than 1,500 degrees Celsius, and this temperature will continue to rise, at least above 1,600 degrees Celsius, taking into account the cooling effect.

How to efficiently and cheaply obtain high temperatures of 1600 degrees Celsius is the key to portable metallurgical plants. The Doomsday Factory, which won the bid, uses a method of obtaining heat energy from deep underground.

The temperature of the earth's crust changes more dramatically than in the atmosphere, but it is not possible to dig tunnels indefinitely with today's high-tech means, and it is now difficult to dig all the way to the mantle where the temperature is high enough to liquefy rocks.

Scientists also need a second way to raise the temperature of several hundred degrees by a large margin for the first time, using the conversion of matter in the liquid and gaseous states will take away the heat and bring the heat, scientists have been able to raise the temperature of more than 500 degrees to more than 1600 degrees after painstaking research.

The diameter of such a device can be as thick as a large bucket. To obtain heat in this way, the plant needs to drill through two tunnels, which must be more than 20,000 meters deep, almost to the edge of the earth's crust.

The two tunnels were needed because the equipment needed hot air to circulate continuously above and below the surface to generate electricity and drive the heat pumps.

The excavation system will use a striker hammer to squeeze out of the tunnel and a vacuum chamber material as a power to lift the striker to a certain potential energy height.

This striking ram is also an important component, as the entire striking hammer system is initially dropped from a height of 30 meters and hits the ground, shattering the backlog of rock and soil. By the second half of the operation, the height of this free-falling-powered ram will reach several thousand meters.

On average, it takes 3,000 seconds, or 50 minutes, to drive 0.1 meters without a ram, and at this rate, it would take the plant 20 years to open a 20,000-meter tunnel.

However, the director of the project told Mr. Besh that their data was only preliminary in the lab, and that they were working to reduce that time to a year's level.

The first is to increase the weight of the ram and reduce the average impact time from 3,000 seconds to 300 seconds, so that the excavation time from 20 years can be reduced to two years.

Although this efficiency is not particularly satisfactory, it is already reluctantly acceptable. After all, their doomsday equipment is to build such a factory when it has lost nuclear energy. If nuclear energy were still alive, there would be no need for them to resort to such inefficient practices.

Two 20,000-meter tunnels were opened to extract 500 degrees of air from the ground to the surface, so that the mini-factory had enough heat and electricity.

Most of the metal can be recovered from the waste used by humans, but their mission at the Doom Factory is to mine from scratch from the earth's crust, and the aforementioned method of using metal jets to crush the soil to the extreme can be used in the mining process.

However, this time it was more demanding, because they were dealing with extremely hard ores, and the method now used by the laboratory was to replace metal particles with diamond particles. With the advancement of science and technology, the cost of diamond particles has long been about the same as that of cabbage, which is not a luxury solution.

Ultrasonic stratification of the ore crushed by the diamond jet can eliminate most of the traditional chemical filtration technology, which also reduces a large amount of pollutant emissions, which is also a practice adopted by the entire metallurgical industry.

In the steelmaking process, the plant also needs pure oxygen to replace the carbon in the iron ore and release it as carbon dioxide. And for today's technology, extracting pure oxygen has become a piece of cake.

The factory will use a micro-turbine called carbon nanotubes, under high pressure, all the components in the atmosphere will be liquefied one by one, the liquefaction time varies slightly depending on the composition, once a gas is liquefied, the rate at which it passes through the carbon nanotubes will change significantly with the gas, and the carbon nanotube turbine uses this speed difference to obtain different components.

This highly efficient turbine separation technology can extract pure oxygen and other usable gases, such as nitrogen, the main source of nitrogen fertilizers, at the same speed as "domestic tap water" in a plant with a length of about 5 meters and a diameter of about 30 centimeters.

Carbon nanotube turbines are a good thing, in the aerospace industry, the use of hydrogen fuel is still quite extensive, and the production of hydrogen fuel by electrolysis is an important scenario for the application of carbon nanotube turbines.

The traditional process of electrolysis of water wastes a lot of energy, most of which is lost as heat, while in the efficient process, high-purity water is pressed into carbon nanotubes, at this time, water molecules pass through the nanotubes in the form of almost a single molecule, and the water molecules absorb almost all the energy of electrical energy in a small space and decompose into oxygen and hydrogen.

The two gases are then separated by a rate difference. This is the mechanism of modern electrolysis of water. How efficient is this water electrolysis?

Outdoor enthusiasts can use this method to ignite fires, as long as outdoor players can find a stream with a little potential energy in the wild, and put the device in it, they get two things: first, water raw materials that can be used for electrolysis, and second, potential energy of water that can be used to generate electricity (this is common in mountainous and hilly areas, and small waterfalls are also available).

In this scenario, a lighter that almost never goes out appears, and it is a lighter fueled by hydrogen, how much is the volume of such a tiny device? The answer is: only the size and weight of a book.

However, because it involves a very complex carbon nanotube turbine technology, only hardcore outdoor players will have this kind of black technology equipment. As you can imagine, a dozen of these "lighters" in a circle can act as a reliable hydrogen-fueled stove.

Barbecue and cook outdoors, nothing at all.

Yuanzhou Rat is now quite familiar with the owner of the outdoor store, he saw this super outdoor equipment in the store, and was deeply attracted by the product description.

"How much does this thing cost?" He asked the owner, Brad.

Brad replied to him, "Ten thousand golden eggs!" ”

This number startled the Yuanzhou rat classmate, and he exclaimed: "Wow, this little thing has 10,000 golden eggs, what a robbery!" ”

Boss Brad smiled and said, "Carbon nanotube turbines are not something that can be produced by a random copycat factory. What's more, it is this super structure that electrolyzes water with an efficiency of 99% energy conversion rate. ”

The Rat was interested in the device, but he still thought it was too expensive. He complained, "Isn't this just a lighter? Even if you rent a luxury RV, you can rent it for two years. it! It's better to live in the wild by drilling wood for fire. ”

Speaking of drilling wood for fire, the boss came back to work, he said: "Eh, don't say it, I have a good equipment here, which can make drilling wood for fire more efficient." ”

Yuanzhou Rat Jun followed the boss's instructions to a cabinet and saw a few words written on it: * furnace.

The boss continued: "The biggest problem with making a fire in the field may be to spend a lot of energy to collect dry firewood, so water is a big obstacle to the use of biomass energy, if you want to drill wood for fire, you may need to get it on wood with high humidity for several hours, and if you can get very dry firewood, you can imagine, maybe three or two clicks can be done."

The most important core component of this thing is the carbon nanotube turbine, but the manufacturing of this turbine is not difficult, and the purpose of its existence is only to extract the air and moisture in the confined space to form a high-vacuum drying chamber, which can remove almost all the water in firewood.

It only takes an hour to turn a stack of soggy firewood into dry firewood. In the wilderness, the last thing that is lacking is trees and grass. It's just that they don't burn easily in a normal state. Now here's the good news!

All you have to do is throw the firewood into the 'stove' and your job is done. Maybe you only need to spend 5 minutes, and you can compare to the hard work of 5 hours! This thing only needs 1000 golden eggs, isn't it cool? ”

The Far Continent Rat had nodded busily, and by the time he had reached this point, he was already quite shocked by the level of technology in the Empire. Ignition was a big problem for primitive humans to survive in the wild, and now well, with this thing, you can have an almost endless number of *. It's unbelievably good.

The boss said to him: "I heard that there are still some people living in primitive societies in the deep mountains and old forests, and they often drill wood to make fire, and get a piece of such equipment to sell to the natives, and it is estimated that they can be their chiefs!" Of course, this is against the laws of the Empire, which explicitly stipulate that these 'living fossils' should be protected so that scientists can study anthropology. ”

Yuanzhou Rat: "Yes, if the primitive man saw this, he would definitely be shocked, even I was surprised. ”

He imagined how pleasant it would be to live in the wilderness with endless fire.

The boss said: "As a senior outdoor fan, I can tell you in charge that the most important thing in the outdoors is transportation, and a balloon made of vacuum material is indispensable."

With it, you can go to the sky and the earth, omnipotent, you think, the forward speed of a balloon is 30 kilometers per hour, if you fight for a day and a night without eating or drinking, you can run 720 kilometers away, I think there is no horror area more than 720 kilometers in a straight line of no man's land, you can rest assured to travel to the no man's land, willful play, as long as you don't get bitten by a poisonous snake, everything else is secondary. ”
