Change Earth’s rotation

by

The dams are colossal engineering works that provide numerous benefits to the surrounding cities, such as energy and flood protection. However, They are often accompanied by national and international controversies. And no dam has acquired both renown (and controversial) and the Chinese dam of The three throatsone of the most titanic construction projects on the planet and the largest hydroelectric dam. Its connected reservoir is capable of containing a volume of water so large that the rotation of the Earth has changed, extending the duration of the day by 0.06 microseconds. The three throats. Built along the Yangtze River in the province of Hubei, it was planned in 1919 by the first president of the Republic of China, Sun Yat-sen, as a measure to control the floods of the river and generate energy. But, above all, to become a symbol of China’s power. Although its construction would not begin until December 1994 and would be put into operation in 2009. It has more than 2 kilometers long and 182 meters high. When it is at its maximum point, can contain 42,000 million tons of water. Suffice it to say that 510,000 tons of steel were needed to build it, which would be needed to erect 60 Eiffel towers. What is it for? It has three objectives: flood control, hydroelectric energy production and improve navigation. Keep in mind that the three throats generates today 11 times more energy than the gigantic hoover preythe world’s largest power plant with 22,500 MW. And through 34 huge generators, supports a large part of the Chinese nation. Besides, Helps keep the Yangze River at baythe longest third in the world, during the flood season protecting adjacent cities such as Wuhan, Nanjing and Shanghai. It has slowed the rotation of the Earth. However, there is a price to pay to store so much water. Once the dam reservoir, the weight of the dough, which is more than 39 billion kilos, It is enough to slightly change the rotation of the earth. As? The inertia of the earth depends on its mass (water) and the distribution of that mass with respect to the axis of rotation. The axis of the Earth It is an imaginary pole that crosses the center of the earth from “up” to “down.” The earth revolves around this pole and performs a complete rotation every day. But as the dough is redistributed on the planet, This change slightly alters rotation. And the greater the distance of a mass (relocation of the water from other areas to the Chinese reservoir) to its axis of rotation, the slower it will turn, therefore It affects the duration of earth days. To understand the phenomenon, it is only necessary to visualize the turn movement of an ice skater: if its mass is uniformly distributed (for example, collecting their arms towards the body), it will turn better and faster after a few laps. If the dough changes, rotation and turn also change. The result. That means that raising 39 billion kilograms of water at 175 meters above sea level increases the inertia of the earth and, therefore, slows its rotation. However, according to NASA, the impact is minimal. His scientists calculated That the change of such mass increases the duration of the day by just 0.06 microseconds and makes the earth just a little more round in the center and flatter in the upper part. It has passed other times. In fact, hundreds of phenomena that alter that movement are produced every year. He tsunami that hit the Southeast Asia in 2004 or the 2010 Chilean earthquake They also affected the rotation of the planet. NASA then confirmed that the 2004 Indonesian earthquake had decreased the duration of the day by 2.68 microseconds. What affects us? Nothing. Although it sounds very shocking, the reality is that we will not notice any change. Miguel Sevilla, deputy director of the Institute of Astronomy and Geodesia, He defended years ago in this information article That these phenomena “have no greater significance, apart from the large material and human damage they cause.” Although they serve to warn us of “the effects they have on people, buildings and in nature.” Other controversies that do matter. In fact, beyond how this Chinese dam affects the rotation of the earth, the project has been plagued with other controversies that do significantly affect the life of humans and ecosystems. One of them is the amount of damage that causes the environment. It is estimated that 70% of China’s fresh water is contaminated and The dam could be worsening the situationsince it is based on old waste and mining operations facilities. Every year 265 million gallons of wastewater are deposited without treating on the Yangtze River. On the other hand, when the project was built, 1.2 million people were forced to relocate In new homes. And currently, the Chinese government is still migrating people out of the area.

The “lost continents” of our planet are leaving their trail in an unthinkable place: the earth’s magnetic field

by

Life as we know it depends largely on the stability of the Earth’s magnetic field. But this stability (or the absence of this) depends in turn on factors that we still do not understand. Some of these factors are in the outer space, others instead are thousands of kilometers hidden under our feet. From the bottom up. Huge geological structures located in the land mantle They could be contributing To destabilize the magnetic field that protects the land from radiation and particles from space. These are the “sunk continents”, the large provinces of low speed (LLVP). Sunk continents. This last name is due to the fact that these rock masses located in the deep layers of the land mantle stand out from the rest of its surroundings because the seismic waves move more slowly through them. Through this method we know the existence of two large LLVP, one located under the African tectonic plaque and the other located under the peaceful plaque. We do not know exactly what they are or what is the origin of these rock masses. A hypothesis indicates that could be remains of the impact between the primal earth and a second planet called Theia. The Moon would be one of the results of that impact, another would be that part of The remains of Theia would have been “embedded” on earth, specifically in the mantle, giving rise to these “lost continents.” However, other studies have pointed out that these masses would be formed, at least partially of ocean cortex buried through subductive geological processes, which would make them more close to “lost continents” of the surface of the earth. The new study can be linked to this last hypothesis. Fed by a “fire ring.” The team He modeled the movements Convectives of the land mantle, also creating a reconstruction of the possible movement of the tecton plates on the surface of the Earth in the last 1,000 million years. Thus they found indications that the African dough would contain older and more “mixed” than the peaceful mass, which would contain 50% more oceanic crust, a more “young” cortex and different from the surrounding mantle. This could be explained with the call “Pacific Fire Ring”, A vast network of failures, many of them subductive that little by little they engulf part of the earth’s crust. This “banquet” would have been producing for at least 300 million years and would be serving to feed the Pacific LLVP. The details of the study were published In an article In the magazine Scientific Reportsof Nature. In diversity is the key. Until now, intuition pointed out that these two underground “continents” had a similar composition. The reason is precisely that the two slow down the passage of seismic waves in a similar way, which leads us to the intuition of thinking that these are very similar in their characteristics. However, the team responsible for the new work indicates that this may not be the case. The reason is that the temperature is more than the material that makes these regions slow the waves that cross them. The balance is complicated. The formations are more or less opposite in the Terrestrial globe, which in principle is great news: since these masses influence the way in which the temperature of the earth’s core is spread in higher layers, which in turn affects the conductive movements inside the nucleus of the planet. Since these movements are those that allow the existence of a magnetic field On Earth, the way in which they occur has a lot of impact on this field. If the LLVPs are different, the way in which the field is generated ceases to be symmetrical as one would expect, which gives rise to the appearance of imbalances. Discussing the different hypotheses. As we pointed out at the beginning, the new study can be linked to the idea that the LLVPs are the result of the sinking of earth cortex pieces and not the remains of a planet of the original solar system. Although the study does not offer conclusive evidence confirming this first hypothesis, It can be seen as a new more test in this address.

China’s domain is spreading far beyond rare earths. Even where the US had no rival: the sea

by

While the United States is has launched yet to the search of those minerals and rare earths that China governs well above the rest of the planet, even with the pentagon and the Apple very Inverting a stratospheric sum, Beijing has been adding and building A small empire that begins to make many nations nervous. To Japan and Taiwan, who believed the seas as nobody: Washington. Maritime ambition. In a context of growing strategic rivalry with the United States, China has intensified their Naval operations long range as part of an explicit demonstration of its global ambition. Already We tell it: Between May and June, the aircraft carriers Liaoning and Shandong They carried out combined exercises in waters near Japan, operating beyond the so -called “First Islands Chain” and entering the “Second Chain”, including Guam in Equation, an important military enclave United States. Nerves The presence of these two aircraft carriers in the Western Pacific not only caused Concern in Japanbut also revealed the New scope of the Chinese Navy, which seeks train their units To operate independently, far from the continental coasts, both in peace and war times. The ability to perform air operations from ships in open sea (including Removal and landings of fighters and helicopters up to 90 times a day) provides China an operational experience that, although still incipient, anticipates a future use of these assets as force projection instruments beyond their immediate influence areas. Shandong Inroads under construction, in 2019 Aircraft carrier as a message. Beyond its military utility, Chinese aircraft carriers represent a powerful status symbol international. For the Government of Xi Jinping, the possession and deployment of these ships constitutes an affirmation that China has left behind the limitations of a regional power and progressly advanced towards the image of global power. Even though Three Chinese aircraft carriers current (the liaoning, the Shandong and the still inactive Fujian) operate with conventional propulsion and are below technologically of the Eleven nuclear aircraft carriers From Washington, his exercises are promoted in official media as an unequivocal signal of the country’s maritime rebirth. And one more when falling. In addition, the possibility that The fourth carriercurrently under construction, use nuclear propulsion and electromagnetic catapults indicates a gradual but ambitious evolution. Plus: The recent opening to the public Shandong in Hong Kongafter completing their maneuvers, reinforces that nationalist propaganda approach aimed at strengthening the legitimacy of Chinese leadership through military power. CNS FUJIAN Dispute for the Pacific. China’s aircrafts not only serve for training or to project distant influence, they also constitute a Operational tool Within the framework of Territorial disputes Activated in the Sea of South and Eastern China. Analysts agree that Beijing could use them to reinforce your claims in front of Japan, South Korea or Southeast Asian countries, or even to exert coercive pressure on Taiwan through A maritime block that prevents the flow of goods and communications. Although in a direct conflict with the United States the aircraft carriers would be vulnerable to missiles and torpedoes (and would probably have a limited role in a immediate confrontation by Taiwan), its value lies in the control of broad areas, surveillance, political intimidation and support for combined naval operations. As He pointed out A Japanese academic to NYT, these platforms allow pressure on both military and civil vessels, becoming a hybrid instrument of economic and military coercion. Evolutionary logic. From the Strait crisis from Taiwan in 1996, when the United States deployed two combat groups Of aircraft carriers to deter Beijing, China understood the need to develop its own naval response capacity. The starting point was the acquisition of the helmet of An old Soviet aircraft carrier In Ukraine, converted into the Liaoning and incorporated in 2012. Since then, the advance has been progressive but constant. The Shandong, released in 2017was the first built entirely in Chinese shipyards, while The Fujianeven in the test phase, it incorporates for the first time a system of Electromagnetic catapultkey technology to operate heavier and better armed aircraft. A long way. Despite these advances, experts like Narushige Michishita They warn in the New York Times That Chinese naval operations are still in a rudimentary phase, marked by a slow but disciplined learning curve. China prefers to avoid expensive errors and seeks, however, consolidate a coherent maritime doctrine and functional that allows, in a few decades, to compete from you to you with the great naval powers of the world. The Indo-Pacific Theater. Plus: the simultaneous display Of the Liaoning and Shandong in deep waters, it has a double value: it allows the Chinese fleet to operate in unknown environments and reinforces its capacities for future intervention scenarios in critical areas, such as the Indian Ocean, the Persian Gulf or even the Mediterranean. According to him Timothy Heath researcher of the Rand Corporation, the aircraft carriers will offer China the ability to project aerial missions in any balloon area Where your Navy sails, beyond the only foreign base that currently maintains in Yibuti. In that sense, the control of routes to the Middle East or the Strait of Malaca, vital for Chinese economic and energy interests, will probably be one of the Strategic objectives in the medium term. A symbols war. I remembered the Times that, as Beijing builds More warshipsconsolidated alliances with African countries and reinforces its port diplomacy in Asia and Africa, the Indo-Pacific converts On the board where a new naval power competition is outlined, with the aircraft carriers as a tool of that Geostrategic ambition. While the aircraft carriers do not guarantee maritime domain (especially in front of a power with Interdiction capabilities as the United States), its value lies both in its operational function and its symbolic weight. In other words, Beijing is no longer satisfied with defending their coasts, but with drawing routes on waters that, until recently, only dominated Your main rival.

Japan believes to have the largest deposit of rare earths hidden on a tiny island. And it is already date to extract them

by

The Rare earth They are an element of great economic and geopolitical value and China stands as the greatest power. To its Japanese neighbors He didn’t make any grace have to depend on them and, after an exhaustive search, a year ago they found the treasure: A huge site of rare earths at the bottom of the ocean. Japan has already set date to start extracting them. January 2026. It is the date on which Japan will begin with the first test extraction, according to Nikkei Asia. They expected to start this year, but the delivery of the necessary duct to reach the deposit did not reach last May and delayed the project for a year. The duct, manufactured in the United Kingdom, has cost 12,000 million yen (about 71 million euros) and will allow them to reach a depth of 5,500 meters. The Chikyu. The Japanese Marine-Terrestrial Science and Technology Agency or JAMSTECfor its acronym in English, will use the chiichyu, the name received by the Japanese drilling boat with which these valuable minerals will extract. In 2022 they already did a test at 2,500 meters deep In front of the coast of the Ibaraki Prefecture, but the challenge they face now is to drill more than double deep: 5,500 meters. If they get it, it would be the first time that rare earths are extracted to so much depth. In the first phase, Chikyu will extract 35 tons of mud. It is estimated that a ton of mud contains about 2 kilos of rare earths, so, in the best case, we could be talking about 70 kilos of rare earths. A key discovery. As we said, Japan found the site almost a year ago in front of the island of Minami-Torishima, located about 1,900 kilometers southeast of Tokyo. The site is located in the exclusive economic zone of Japan, so their extraction corresponds to them. Among the minerals it contains, one of the most abundant would be gadolinio, used in the nuclear industry, and the disposium, used mainly in magnets for electric vehicles. It would also be rich in manganese, cobalt and nickel nodules, key components in the creation of batteries. The amount is not clear and is decisive. At first there was talk of a site of 16 million tons, which would place Japan in third place behind China (44 million) and Brazil (21 million). However, a Analysis of the University of Tokyo He pointed to the loot would be much more juicy: 230 million tons. If confirmed, Japan would overcome China and be placed as the largest reserve of rare earths in the world. Independence. Japan’s efforts to find rare earth date back to 2022 and had a clear goal: to be independent. Currently, Japan depends on imports to meet their needs of rare metals, with 60% of them from China. The Japanese government invested 6,000 million yen (about 42 million euros) in the first extractions and have made it a priority since then. Friction. As we said, China currently has the largest reserve of rare earth and that gives it A huge power. Just a few weeks ago something unusual happened: A combat fleet, headed by two Chinese aircraft carriershe entered the Japanese ZEE near the island of Minamitori. Japan He did not confirm If he presented a formal protest and just declared that he had sent “the appropriate message.” It is not the first time that China enters the Japanese area, nor are the friction between the two countries, But it is certainly a somewhat controversial maneuver given the economic importance of the area.

This city of China is the world epicenter of rare earths. The problem is that nobody thought of its inhabitants

by

To get an idea to what extent It has control Of those precious minerals that form the set of rare earths, the greatest enemy that China has is not outside its borders. It is such a monopolization in the sector that the danger has in “house” through of the smugglers. And of all enclaves, one stands out greatly as an epicenter of the entire heart. His name is Baotou, and everything that shines for the surrounding inhabitants is not gold. A normal city in appearance. Baotouan industrial core of 2.7 million inhabitants on the border with the Gobi desert, seems to the naked eye a second category Chinese city like so many others: shopping centers with western chains, local restaurants overflowing and children playing late. However, a short journey to the outskirts is enough to discover His true nature: A landscape dominated by factories, smoking chimneys and an environmental legacy forged by one of the most strategic and persecuted sectors of the planet. The heart of rare earths. Yes, the enclave houses More than 80% of the Rare reserves of China. Since in the 30s they were discovered in the nearby Mining District of Bayan Obo elements such as Cerio, Lantano or Samario, its exploitation has turned the city on a chain axis on global supply on industries such as electronics, automotive and defense. We have counted before: During the 90s, China increased its production by 450%, while other countries, such as the United States, They closed their mines. This concentration made Beijin the almost exclusive supplier of these critical metals, and today, in the midst of the commercial war with Washington, its control has been transformed In diplomatic weapon. Economy vs Human Cost. The problem? The Guardian told that mineral wealth has favored the economic development of Baotou, whose GDP per capita It widely exceeds the national average. However, prosperity has Your reverse: Processing plants generate toxic (often radioactive) waste that are discharged into huge artificial rafts. The most infamous, the Weikuang dam, for years was the largest landfill of rare earth waste on the planet, without adequate coating and directly close to the Yellow River. In fact, official reports have confirmed that these activities caused a 87% decrease of ammoniacal nitrogen in a tributary between 2020 and 2024, although accumulated ravages remain visible. Yin mountains on the outskirts Cancer and poison. For example, numerous studies They have documented devastating consequences in the health of nearby communities: from bone malformations to a “Epidemic” of cancer. Exposure to these elements, capable of crossing the blood brain barrier, has been associated with motor and sensory disabilities, as well as alterations in fetal neurological development. Not just that. 2020 investigations revealed that the dust of the streets contains concentrations so high that the children of Baotou and surroundings are exposed to dangerous levels Just to breathe. Daily particle ingestion rates in mining areas far exceed the limits considered safe. A washing … halfway. Given the growing international criticism, China has tried to clean its image. In 2022, state media announced that Weikuang’s dam had been transformed into an urban wetland, now supposed paradise of migratory birds. The reality? Explained the medium British that when arriving at the place, what one is located is a concrete wall that hides a dry and desolate lodazal. Behind, ruins of ancient “villages of cancer” and oxidized industrial structures extend. New homes built for displaced are practically empty, and foreign journalists are It usually blocks actively to prevent them from talking to residents. Rural sacrifice. So things, Baotou exemplifies an uncomfortable truth: the China domain In the rare earth market it has been possible not only for its geological reserves, but for a political decision where rural communities have been allowed to support Toxic costs of a globalized economic boom. It is not an exempt problem from China, of course, the same thing happens in other sectors such as AI and its data centers (we recently counted it with the Elon Musk Supercomputer). Be that as it may, and although there are less polluting technologies to process these metals, they are rarely used: its implementation would make the low costs that have cemented the Chinese position. If you want, in a context of growing international pressure and commercial sanctions, the extractive model It reveals both the fragility of environmental balance and the rawness of contemporary geostrategic priorities.

The key to China’s success with rare earths are not the rare earths: it is the magnet

by

The response of the Chinese administration to the tariff pressure to which the United States wanted to submit in early April was immediate: significant restrictions on the export of rare earths. A measure that ended up relaxing this week, with the granting of licenses of export for six months. A truce to which the United States accessed by lowering another of the key elements in this commercial war: The admission of Chinese students in American universities. These are one of the most important pieces of the geopolitical board: they are scarce chemical elements, difficult to extract and refine, and a key resource For the technological, automotive and energy industry, among many others. China is controlling access to these elements to defend their interests, but the key is not just to isolate its rivals of this precious material: is in the disability outside China to take advantage of them. China is the fundamental piece in its prosecuted. China controls rare earth production by 70% and 90% processing them. In the case of heavy strange earth, a subgroup of them even more scarce, their participation in the refining is 99%. According to the newspaper The New York TimesChina has up to 39 university programs so that its students can train and develop their career in the chemical industry specializing in this field. It is just a sample of the importance it has for the country led by Xi Jinping to continue controlling this geopolitical weapon. This graph is the best visual test of China’s domain in rare earths. The access toll. Although the focus on how they are affecting the restrictions on the export of rare earths to the supply chain is currently, there is a key that has gone unnoticed: the real problem is not access, it is the difficulty of working even in the case of obtaining them. When the Ministry of Commerce of China and the General Administration of Customs They imposed access controls for the export of medium and heavy rare earthsthe supply chain staggered. From their entry into force, all exporters were obliged to obtain specific licenses for each shipment, even if they are products in which they have already been refined, such as magnets. Why touch the rest. These licenses are a complex bureaucratic process, slow and studied case by case. Although the primary political objective is the United States, European companies that need heavy land (or materials manufactured with them, such as magnets), are seeing supply interruptions. Suzuki has already arrested swift production in Japan Due to the scarcity of pieces, Musk You are having trouble building your robots and, in Europe, the secretary general of CLA (European Association of Automation Suppliers) made an urgent call: production is entering the paralysis phase. “With a deeply interconnected global supply chain, China’s export restrictions are already paralyzing production in the European supplier sector.” The magnet as geopolitical treasure. William Huo, ex-intel and one of the most prominent figures in the critical analysis of Western industrial policy, summarizes it in the best possible way: West has been focusing on optimizing spreadsheets instead of factories, And now he is not able to manufacture a single magnet. The industry depends on the Chinese refining of rare earths to manufacture high performance magnets. Without them, there is no competitiveness in electric cars, defense, nuclear or consumer technology. The rest is not prepared to refine rare earths. “Middle East has oil. China has rare earths.” They are words of Den Xiaoping in 1992, who was the top leader of the People’s Republic of China. The country has been acquiring the necessary knowledge to extract and refine these materials, while the rest of the world enjoyed a comfortable (and economic) dependence. West has tried to self -abuse with at least 10% of the remaining rare lands. Countries like Norway and Sweden are finding new deposits, and have confirmed the intention of exploiting them not beyond 2030. None of this is enough. Refining is the main bottleneck for the use of rare earths in industry, an expensive, sensitive process and with complex waste management.

He Rare Earth Agreement announced last night says more than what appears to be a simple commercial truce: China has the most sophisticated geopolitical weapon we have seen. One that is capable of paralyzing entire sectors of any developed economy. And with the elegance of who closes a tap. China controls the entire ecosystem of Rare earth: The Ganzhou mines. Processing plants. He know-how technical. Specialized labor. Even the only American Mountain Pass mine Send your material to China to refine it. It is the same difference between having oil and controlling the refineries of the world. China has built a monopoly on elements that are the blood of the digital economy: Without neodymium there are no wind turbines. No Disposio there are no Tesla engines. Without Terbio there are no iPhone screens. Deng Xiaoping He saw it in 1992: “Middle East has oil. China has rare earths.” Three decades later, That prophecy is a reality and a definition of the present. And the interesting thing is that West has financed its own vulnerability. For decades, US and European companies outsourced the extraction and processing of “dirty” minerals to China, celebrating the margins that gave them that specialization. That dependence has had a strategic cost. And now… The same companies that built the supply chains to maximize their efficiency now discover that they also optimized their vulnerability. And China executes in a way we could call “civilized blackmail“. It does not close the whole tap, but it does slow down the supply with bureaucracy. Ask for forms, photos of the factories, customer listings, production details. That, in addition to a bureaucratic nuisance, is also to open a window to the industrial secrets of its competitors. Industrial espionage, but institutionalized, disguised as commercial policy. You take it or leave it. When he negotiates, he does it from a position of strength. The agreement, of only six months, works as a constant reminder. Each western company now knows that its production depends on Chinese benevolence. And if a geopolitical escalation of any kind arises, the industrial blackout can be almost instantaneous. The West now discovers that economic interdependence can become a lethal weapon, because China has shown that in the technological era, who controls critical materials controls the rules. The agreement last night postpones the moment in which the West will have to decide if he is willing to pay the price (economic and strategic) to recover his mineral sovereignty. China has won this pulse and has plenty of strength to win all the following. In Xataka | China monopolizes rare earths.

China has emerged a new problem with its rare earths: smuggling

by

China is deploying police, customs agents and even spies to stop the smuggling of its increasingly precious Rare earthcritical minerals on which it maintains an official embargo. Why is it important. The Asian giant The world production of these materials is obsessively controllingessential for the car, technological and military industry. Its new anti -policy campaign aggravates even more the shortage that US and European companies are already suffering, who are not finding short -term alternatives. The context. China cut legal exports of seven types of rare earths –and magnets manufactured with them– last April 4. The measure is part of a pressure strategy for the United States to reduce tariffs on Chinese products and allow the sale of sensitive military technology to China. Yes, but. Smuggling had historically been an escape valve. Chinese organized crime unions came to traffic half of the country’s annual production before 2010. Multinationals such as Boeing, Volkswagen and Toyota depended on supply chains where legal and illegal production was mixed, according to a report from The New York Times. Between bambalins. Senior customs, trade, police and intelligence services met on May 9 to Plan the offensive. Three days later, representatives of eleven national ministries and seven provinces issued a joint statement: the control of strategic mineral exports is “related to national security.” In detail. The new license system demands thorough documentation. Complete traceability. Chinese companies have to certify not only who buys the material, but how it will be used at each subsequent stage of production, including photographs of final products. This information, in addition to avoiding smuggling, can also become a detailed map of the use of rare earths abroad for the Chinese government. And that would facilitate future attacks directed against specific companies and countries: they will know who will produce what. The facts. Traditional smuggling routes have been complicated: With the scarcity getting worse outside China and prices shooting, the potential benefits for smugglers willing to assume the risk are enormous. But new security measures make the game more and more dangerous. Outstanding image | Lio voo In Xataka | China has executed three master moves to break the technological dependence of the West.

China’s absolute dominance over rare earths is the result of a strategy that no one else has. Not even the US

by

The Rare earth They have a leading role in the commercial, technological and geostrategic war that the US and China support. These chemical elements are relatively scarce, and, in addition, they are not usually found purely in nature, but what makes them so special are Its physicochemical properties. In fact, thanks to them they have established themselves as A very valuable resource In numerous industries, especially in electronics and renewable energies. During the last year and a half the Chinese government has used its control of these chemical elements to defend their strategic interests In full confrontation with the US, Europe and its allies. The interesting thing is that it can do it because it produces approximately 70% of rare earths They are distributed in the world market, and, what is even more important, controls 90% of the processing industry to which it is necessary to submit rare earths so that they can be used. China refines 99% of the weighing land of the planet At the current US tension situation, Europe and its allies need to bet on their independence and consolidate their own supply chain. They are in it, but they don’t have it easy. The old continent in particular has been proposed to self -abuse At least 10% of rare earths He needs for 2030 thanks to the exploitation of the new deposits, such as the one he found in January 2023 the LKAB mining company near the city of Kiruna, in northern Sweden. China’s starting point is very favorable. As we have just seen, with a 70% production of the global market and a control of 90% of the rare earth processing industry this Asian country has this absolutely controlled market. However, we have not yet repaired in a figure more that is also very important: China refine no less than 99% of the heavy lands of the planet. These chemical elements are a subgroup of rare earth characterized by its greater density and lower ionic radius. Heavy rare earths are a subgroup of rare earths characterized by its greater density and lower ionic radius In addition, heavy rare earths are less abundant in the earth’s crust than the light ones. To this subgroup belongs as elusive minerals and with names as exotic as gadolinio, the terbio, the display, the holm, the erbium or the tulle, among others. How can we intuit, China does not control 99% of the processing of this kind of rare earth by chance. This absolute leadership is the result of a strategy in which teaching institutions are having an unquestionably protagonist role. And, according to the newspaper The New York Timesat the moment China has 39 university programs of chemistry specialized in rare earths. Presumably in these training programs students acquire the necessary knowledge to develop their professional career in the chemical industry specialized in rare earth processing. There is no doubt that this is one of the great strengths of the country led by Xi Jinping in this area, especially if we keep in mind that US universities currently do not offer a single specialized program in rare earths. The article published by The New York Times does not collect it, but in all likelihood European countries that have a greater dependence on rare earths, such as Germany or France, as well as Japan or South Korea are in the same situation as the US. These countries will cost a lot of time to acquire the favorable inertia that China has objectively, so it is reasonable to anticipate that in the short and medium term the rare earth processing industry will continue to be led by strong by the country headed by Xi Jinping. This Jens Eskelund statementthe president of the Chamber of Commerce of the European Union in China, clearly reflects what the US and Europe face: “Some approvals are coming (the result of negotiation with China), but they are far from being enough to Avoid imminent stops in production. We still face A great interruption in supply chains“ Image | Volker Braun More information | The New York Times In Xataka | We already know what is the best natural factory of the precious rare earths: a cosmic kilonova

To this peculiar group of chemical elements belong some metals as elusive and with names as suggestive as neodymium, promised, gadolinium, ititrium or scandio, among others. Some of them They are relatively scarceand, in addition, they are not usually found purely in nature, but what makes them so special are their physicochemical properties. Its characteristics are beyond the reach of the other elements of the periodic table, which has caused that during the last decades they are consolidated as A very valuable resource In numerous industries, especially in electronics and renewable energies. They are involved, for example, in the manufacture of hybrid and electric cars engines, batteries, semiconductors, catalysts, optical fiber, LCD panels, and even in wind turbines. Europe wants to stop being in the hands of China once and for all China dominates the rare earth industry with an indisputable forcefulness. According to him US Geological Service For many years it has produced more than 90% of this valuable resource. In 2022 its market share was reduced to 70%, but did not do so because of a decrease in production; This fall had its origin in the increase in rare earth production quota experienced Australia, Vietnam and Myanmar, among other countries. In addition, the country led by Xi Jinping also dominates the processing industry to which it is necessary to submit rare earth so that they can be used. So much so that according to Xincaifu Its quota if we expressly stick to the global processing industry ascends 90%. And with a 70% production of the global market and a 90% control of the Chinese rare earth processing industry has this absolutely controlled market. The Chinese government is using its control of rare earths to defend their strategic interests in full confrontation with the US The government of this Asian country is using its control of these chemical elements to defend their strategic interests In full confrontation with the US, Europe and its allies. In this context, the old continent needs to bet on its independence and the consolidation of its own supply chain. And it is in it. In fact, Germany has just made a very important contribution in a scenario of fundamental use of rare earths: the manufacture of lasers. These devices are used to produce medical equipment, in scientific research, in the manufacture of consumer electronics, and even in the tuning of Quantum computersamong many other industries. Rare earths are used to dopar the crystals That, very broadly, they are responsible for amplifying the light before emitting it with a fixed wavelength. The problem is that if these chemical elements are not available the production of high quality lasers is not viable. Well, it really wasn’t until now. And it is that the Fraunhofer Institute of Optronics, which is located in Karlsruhe (Germany), has found a way to manufacture the crystals involved in the production of lasers without using rare earths. In fact, we can see some of these crystals in the cover photography of this article. During its manufacturing process it is essential to minimize impurities and preserve the polarization properties of the crystals, but, apparently, the researchers of the Fraunhofer Institute have given in the Diana. Your plan now goes through developing production processes that guarantee the supply of these crystals that Europe requires.
