Wandering Spaceship in Deep Space Chapter 407: 1 major earthquake

　　 "Yes, it is really troublesome." The mechanics expert discussed: "Many technological advances are essentially advances in materials science."

　　"If there is a lack of rare earths, it will be difficult to make progress in materials science, and naturally, there will be no powerful engines. Even some composite ceramics require rare earths."

　　How important is rare earth?

　　In materials science, it is as important as petroleum!

　　 Take the engine as an example: In the era of turbojet engines, the gap between the turbine blades and the casing is wide, the temperature in front of the turbine is lower, and the deformation of the turbine blades during operation is within a controllable range. Conventional materials can still Will be used.

　　 In the era of turbofan engines, the temperature in front of the turbine of the high-pressure turbine is higher, and the tip clearance is also smaller. The problem of the deformation of the turbine blades becomes particularly prominent. The main element to solve this problem is rhenium. The addition of rhenium to nickel alloys can significantly increase the creep strength of the alloy, and it can also resist deformation well under long-term work.

　　If this element is lacking, then the Taipu people will develop turbojet engines and they will not be able to develop it anymore. No matter how smart they are, it is difficult for clever women to cook without rice.

　　 Most of the things that can be used on mobile phones are light rare earths, and the reserves are pretty sloppy, but heavy rare earths like rhenium are very rare.

　　"The mineable rhenium resources on the earth are only 2500 tons. This planet may be even less, perhaps only...100 tons? Such a large planet is useless at all."

　　 Zhang Yuan couldn’t help asking: “Our current material technology has widely used composite ceramics and nanomaterials, right? Many materials do not have rhenium. Is it possible for them to jump into technology.”

　　 "It is impossible. There are many materials that still have to use rare earth elements. It is more because we have developed for hundreds of years...no, thousands of years. Your Captain, we are already a third-level civilization." This scientist Said: "You have to eat one bite at a time, and the road has to be taken step by step. Without the previous results, it is impossible to have funds to study the follow-up results."

　　 "If you can't even research on ordinary propeller airplanes and jet engines, how can it be possible to get to the sky in one step and come up with our ramjet?"

　　 This is also one of the important reasons why the Taipu Civilization has so far not produced an aerial vehicle. Not only is the money not in place, but the lack of materials is also a major cause.

　　Of course, the Taipu civilization still faces the fourth difficulty, that is, the problem of too thick atmosphere and difficulty in launching rockets.

　　 The friction coefficient of the atmosphere is proportional to the air density. Rockets flying at high speeds will experience greater resistance. At the same time, the high temperature of the rocket's surface also places more demands on materials science.

　　"If this civilization wants to launch rockets, it must have higher-performance materials. However, this difficulty is the simplest one, and it can be overcome by barely."

　　"The above is the objective environment currently facing the Taipu people, all of which are difficult points."

　　 Hearing this, Zhang Yuan frowned, "Compared to humans, the Tap people are really a very unlucky civilization...So, if I were the leader of the Tap civilization, I would use human hands to launch some Satellites are indeed a very cost-effective thing."

　　 Li Zhendong said: "As for the next few decades, this batch of satellites will be scrapped. Whether there is another batch of satellites or not is actually not important. Anyway, I am no longer in office, and I will probably retire. The people will only read me well."

　　 "You are very politically conscious."

　　 Then, suppose the Enlightenment civilization really came to this planet 150,000 years ago. After they have surveyed the entire planet, they should be able to foresee these difficulties. How can they help them? In particular, this kind of help may happen hundreds of thousands of years later.

　　This issue is very complicated, and the Enlightenment civilization has always disliked direct gifts.

　　"If it is a human being, it is really difficult to help without directly donating technology. Especially, the other party was a group of primitive people 150,000 years ago... High gravity, high pressure, lack of rare earth elements, how to solve it? ?? Talking to primitive people about rare earths and the like, they don’t understand."

　　 The expert said excitedly: "...So we followed the idea of ​​archaeology to study what major events happened 150,000 years ago, whether it was natural disasters or **. If this happened Sufficient influence will definitely be able to find some clues in history."

　　 "Sure enough!"

　　"A super earthquake broke out from the ocean 150,000 years ago!"

　　"It is conservatively estimated that the magnitude of the earthquake has reached at least 13."

　　 13 magnitude earthquake!

The difference in magnitude of 　　 is 1.0, and the difference in energy is about 32 times. In other words, a magnitude 6 earthquake is equivalent to 32 magnitude 5 earthquakes, and a magnitude 7 earthquake is equivalent to 1,000 magnitude 5 earthquakes.

　　 Then, a magnitude 13 earthquake is equivalent to a magnitude earthquake!

　　 such a super earthquake can already cause the shift of the crustal plates.

　　At that moment, a huge tsunami occurred!

　　A large number of volcanoes erupted at the same time, and the dust covered the world's sunlight. Immediately afterwards, because of the drastic drop in temperature, which brought heavy global precipitation, a small ice age caused by earthquakes was born.

　　 The duration of this Little Ice Age is not too long. It lasted for more than two years. A large amount of precipitation caused the dust in the sky to fall again, revealing bright sunshine.

　　 Two years, there will be no mass extinction of species.

　　 However, the Taipu people have not yet investigated the specific cause of this earthquake. They can only attribute the ambiguity to the movement of the crustal plates.

　　 Zhang Yuan couldn’t help asking: “So, is this earthquake related to the Enlightenment’s civilization? Could it be said that rare earth elements appear in large numbers in volcanic eruptions and earthquakes? It’s a little bit possible... But this method is too great. A little rough...explode?"

　　 This is the intuitive thought of many people~IndoMTL.com~ so that everyone will be surprised and speechless for a while.

The scientist on the 　　 platform couldn’t help but smiled bitterly, and then said: “We first investigated the area where the earthquake occurred. There is already a deep sea area, and the deepest trench can reach 30,000 meters. I think, even if the deep sea area contains huge reserves. Taipu Civilization has no way to develop the mineral resources of China."

　　 "Thirty thousand sea waters, even we can't develop it."

　　The ocean is indeed a huge treasure house. The deep seabed manganese nodules are well-known deep-sea minerals, containing more than 20 elements such as manganese, iron, nickel, and cobalt, which have great economic value. However, these mineral sources will naturally occur even if there is no earthquake.

　　 And most of the seabed mineral mining bases are built in shallow waters. Human deep-water drilling generally refers to offshore operations with a water depth of more than 900 meters, and extreme water depth refers to a water depth of more than 1,500 meters.

　　The deeper the water, the greater the difficulty will be. In the deep water area of ​​30,000 meters, even the human submarine seems a bit difficult, not to mention the large-scale development.

　　"It is temporarily impossible to confirm whether the earthquake has an impact on the number of seabed minerals around the world. According to computer simulations, after a major earthquake, there is a certain probability that because of the eruption of seabed volcanoes, there are more seabed mineral resources in the world... We have no way to measure specific numbers."

　　 "However, this earthquake also brought a series of subsequent chain reactions..."
