The most powerful countries and with greater electricity consumption per capita, ordered in this graphic developer

by

He Electric consumption It is a great thermometer for countries. The amount of energy we consume is an economic, but also social, climate indicator, of technological decisions and even lifestyle. The reason is that there is a wide range of factors that influence this consumption, and the following graph prepared by Visual Capitalist We can see what are the 15 countries with the highest GDP in the world which consume more electricity per capita. The surprise is called … Canada. Oh, Canada. The data comes from Ember and reflect the difference between the consumption of electricity per capita of the main world economies In 2024 and the one they had in 2000. A quarter of a century is more than enough to see a change in this regard, but what has not varied an apex are the two nations that lead the graph. Canada occupies the first position with consumption in 2024 of 15,708 kWh per person in 2024. The figure is considerably less than the one that registered 24 years ago and that high consumption is driven by an industry (especially mining and Aluminum production) very demanding at the energy level and for the electricity necessary to withstand the long winters. The United States, with 12,741 kWh per person, is not behind and the reasons are very similar: industry and air conditioning (which is at an excessive temperature both in winter and in summer). South Korea and China. Australia is another of the countries that traditionally exceeded 10,000 kWh per person, but these last 24 years have passed something curious: South Korea has glued a time comeback in this indicator. Here we enter that of electricity consumption as an economic thermometer, by relating the passage of the 6,200 kWh at 12,100 kWh due to an advance in advanced industrialization and manufacturing, especially in the segment of semiconductors and cars, as well as the growth of data centers. In China we live a very similar phenomenon, with a consumption of about 1,100 kWh in 2000 and one of 7,100 kWh currently due to that same technological expansion with the Accelerated industrialization in steelaluminum, electronics, data centers, semiconductors and electric vehicles as main protagonists. In addition, even if it is practically half of the per capita consumption of Canada, we are talking about a population of 1,400 million people compared to about 40 million. To put it in percentage: 17% of the world population compared to 0.5%. Logical. But the increase in consumption in these two countries is not only due to industrialization. Japan also has a strong industry and consumption has remained practically identical. There is another factor: The increase in middle classespecially in China. The increase of living standards, urbanization and electrification in homes has contributed considerably to this increase in consumption. Migration to large cities has generated a boom in construction and electrification due to the use of appliances, services and goods such as electric cars. Now, that is causing other problems, such as a life train incompatible with the formation of families wave Lack of people working in factoriesbeing two of the Shared problems with their neighbors Japan and South Korea. Two prominent outside the graphic. Germany, Spain and Italy have consumption very similar to those of 25 years ago, but if we look beyond this classification for the 15 main world economies, we have two names that eclipse everyone else. On the one hand, Iceland, with an imposing consumption of 51,920 kWh per person, thanks to the fact that there are not many Icelanders (about 300,000), but they do have A very potent industry such as aluminum, as well as very few hours of light and an extreme climate that requires constant lighting and heating. In Norway they also put the heating and light the lights, they also have an industry and a high standard of living that allows high consumption, but something that helps its consumption of 24,580 kWh per capita is a tremendous electric car park. In fact, in 2024, Almost 90% of the new cars sold were 100% electricwith what this entails at the charge level both at home and in public networks- In Xataka | This chart exposes self -sufficient countries at the food level.

The culture of queuing in UK is so powerful that many British suffer a real cultural shock by “asking for the time”

by

“The other day I go to the post office and everyone is sitting everywhere, in a corner of the room, etc … there is no tail.” So explained The British Tiktoker @edwardthelife What for him is “one of the greatest greatest cultural differences: the fact that in Spain” is asked at the same time. “ And it may seem an exaggeration, but (in the light of comments) it makes sense: “An English, even being alone, will form an orderly tail of a person,” said George Mikes and Check the anthropologist Kate Fox: The British loves to queue each other. Or, at least, they have them so within their cultural conception of the world that they make them by default, almost without realizing it. But does it make sense? The theory of tails. As it seemsthe first serious mathematical study on the queues was made by a Danish, Agner Krarup Erlang. His intention was to know how to dimension the telephone switches to attend optimally. At that time, the operators had to manage the calls manually and the intention of the Danish mathematician was how to reduce the queues without spending disproportionate. Since then we have learned a lot of interesting things. For example, now we know that common sense (the solution to bottles is to expand the number of lanes) It doesn’t always work. In the case of roads, for example, there is an optimal number for a certain amount of cars: if the number of lanes above that optimal lanes is wide, cars change too much lane and, in the end, the flow becomes slower. But in this case the two are tails, right? Indeed, the fundamental difference between the “English tail” (to call it in some way) and the “Spanish time” (to call it from another) is not that one is a tail and the other does not, but the rules that govern each one. The second, in fact, is still a social/virtual order without physical training. The English, requiring that all members physically make a line, allows us to better ponder the number of people in front of them. The Spanish, having verbal control, allows people to do things in the meantime (or to wait in more comfortable places). Is there any better than another? From what we know about virtual tails, order without physical formation usually Improve satisfaction of users (to the extent that you release the client from “being planted”). However, this system also encourages abandonment more than the other. That is why, when I wait for her It is not too long And therefore release user time does not make sense, a single long row (especially if there are several homogeneous attention positions) It usually favor the feeling of equity. ANDSa may be the most reasonable explanation. Because, in Spain, there are also physical tails. It is when the wait is long or when the physical space does not allow to create a tail easily when “asking for the time” emerges naturally. So I suppose that whoever has to take note of the Tiktoker comments is the mail itself. Most likely, neither space nor the time of waiting is the most recommended.

Nvidia, TSMC and SK Hynix are the most powerful chip companies on the planet. None can allow any of the others to fall

by

Nvidia dominates the global chips market for artificial intelligence (AI) with a fee that during the last three years has oscillated between 80 and 94%, according to Fourweekmba. Your leadership is supported by A very competitive hardware and a software ecosystem in which CUDA (Compute Unified Device Architecture) It has an essential role. This technology brings together the compiler and development tools used by programmers to develop their software for NVIDIA GPUs. However, the company led by Jensen Huang has a fundamental partner: TSMC. Nvidia designs the chips for AI and this manufacturer of Taiwanese semiconductors, the eldest of the planet with A global quota close to 60%it produces them. Its iron leadership is the result of Its peak technology and its titanic production capacity. TSMC has many important clients, such as AMD, Qualcomm, MediaTak or Broadcom, among many others, but thanks to the AI ​​NVIDIA, it has established itself as Your second best customer Only behind Apple. Presumably TSMC is about to start MANUFACT 2 NM GPU For Nvidia, but this is not the only thing that this chips manufacturer is going to do for one of its best customers. And this Taiwanese company has decided to start An expansion plan for five years of its manufacturing capacity of integrated circuits using its advanced cowos packaging technology (Chip-on-Wafer-on-Substrate). According to Beth Kindigof the I/O Fund consultant, this technology will monopolize between 50 and 60% of the market in 2025 compared to 15% it supported during 2024. The synergy of these companies is indisputable The high demand for GPUs for AI with Blackwell MicroAritectura de Nvidia is largely responsible for the implementation of this plan. The company led by Jensen Huang can respond better to the needs of its customers and will see how its competitiveness is increased in a phase in which Depseek and other Chinese companies represent a challenge. In March 2024 TSMC officially announced which was building two cowos packaging plants in the town of Chiayi, housed in southern Taiwan. However, this is not all. He also shuffled the option to put a plant more specialized in this advanced packaging technology in Japan, presumably on the island of Kyushu, in which this company is currently building two semiconductor production plants of avant -garde. In any case, there is something else. And it is that Chiayi plants will be trained to work, in addition to the packaging cowos, With advanced Info and Soic technologies (System on Integrated Chips). Nvidia and TSMC synergy is indisputable, but this recipe requires a third ingredient: SK Hynix It is evident that TSMC wants to cover your back well and look to the future to prevent its production capacity from being threatened by a bottleneck. An interesting note: currently the Cowos packaging is being used with the AMD Instinct Mi250 chips and with the A100, H100, H200, B100 and B200 NVIDIA GPUs, as well as in its derivatives. The review used in these last two chips, the B100 and B200, is known as Cowos-L. Before the TSMC ends this year, you will be able to process no less than 60,000 wafers per month using its advanced packaging technology. The synergy of Nvidia and TSMC is indisputable, but this recipe requires a third ingredient: SK Hynix. This South Korean manufacturer of memory chips leads the HBM memories market (High Bandwidth Memory) that work side by side with the GPUs for ia with a shocking authority. Your market share Broken 70%so that the remaining 30% are distributed by Samsung and Micron Technology. After them, Chinese manufacturers of Yangtze Memory Technologies Co. (YMTC) and CXMT (Changxin Memory Technologies). At the end of 2024 SK Hynix took advantage of the celebration of an innovation forum organized by TSMC to publicize its mastery of the manufacture of HBM memories. According to SK Hynix itself Its MR-MUF process, which, in broad strokes, is a technology that makes possible a faster punch of the DRAM compared to the TC-NCF process that other companies use, has allowed it to achieve an efficiency 8.8 times higher than that of Samsung and Micron. This simply means that it manufactures its HBM chips much faster than its main competitors. SK Hynix is ​​manufacturing 12 -layer HBM3E memories on a large scale while Samsung and Micron have problems with their production As we can intuit, the speed at which a company that is dedicated to manufacturing semiconductors is capable of producing its integrated circuits deeply condition its competitiveness. It is evident that greater efficiency will allow you supply more guarantees to your customersespecially in an upward market like that of HBM memories. In addition, SK Hynix is ​​manufacturing 12 -layer HBM3e memories on a large scale while Samsung and Micron have problems with their production. In any case, both Samsung and SK Hynix are already working on the development of HBM4 memories with the purpose of catapulting their competitiveness. Here it is precisely where Nvidia appears. SK Hynix announced in October 2024 that he intended to deliver the first HBM4 memory chips to his clients during the second half of 2025. However, Jensen Huang asked him That the delivery advances. Chey Tae-Won confirmed itthe president of SK Group, so it is absolutely reliable information. Why does NVIDIA require so urgently the HBM4 chips? Simply because you need to support your chips for the most capable with the most available energy and energy efficiency memories. And in this field SK Hynix currently has the pan well grabbed by the handle. Image | TSMC In Xataka | South Korea fears US reprisals.

Your grandmother was right with Kiwi, and now science has given her marketing a powerful weapon

by

It is a milestone for European regulation: for the first time, a fresh fruit, the green kiwi, has made the European Commission authorize you A “specific health declaration”. What your grandmother told you now comes with an official stamp and scientific support. But this also gives rise to a Great marketing network. A victory for brands. This news, which at first glance seems a victory for science and consumers, is actually a fascinating case study on how food industry, marketing and European regulation that has more recesses than it seems. The application, driven by the neozygous giant Zespri, has taken seven years to see the light and, although it celebrates a real benefit, reopens the debate on what we consider “healthy” how we sell us. A cooked health statement for years. So that A food can carry a slogan related to healththe inventiveness of a marketing team is not enough. As the Food Technologist explainsMiguel Lurueña in the country, for almost two decades the European Union demands a rigorous process to avoid misleading advertising. The first request for the Kiwi to have its recognition started in 2018 when Zespri, the world’s largest kiwis marketer, submitted a request to the European Commission claiming that the Kiwi contributes to the maintenance of normal defecation. To support him, he contributed 19 scientific studies. It is not something two days. The scientific verdict did not reach 2021, when the European Food Security Authority (EFSA) comes into play. His work is to review scientific evidence and determine if it is solid enough to give your approval. Something that arrived three years after the initial application. The next step was the politician, where the Member States of the European Union had to agree on a statement on this food and its properties. Because obviously it is something that will directly affect their citizens. A text with a small print. The official text approved is: “The consumption of green Kiwi contributes to the normal functioning of the intestine by increasing the frequency of the strokes. “The law allows simplifying it, so get ready to see ads with a clear and direct:” Help to go to the bathroom. “ But the statement will only be able to use for fresh green kiwis of the variety Hayward And the consumer should be informed that the effect is achieved with a daily intake of 200 grams of pulp, which is equivalent to about two kiwis of good size. The kiwi’s “superpower” is not so exclusive. This is where history becomes very interesting. Zespri argued that the kiwi effect was due to a unique combination of factors: its fiber, an enzyme called Actinidinephenolic compounds and other substances that They altered intestinal motility and the Microbiota. It seemed that the Kiwi had a secret formula. However, EFSA itself in its scientific opinion reaches a much less exclusive conclusion: evidence does not demonstrate that the effect of green Kiwi on defecation is higher than the one that could be expected because of its dietary fiber content. Figures can be put. Keep in mind that 200 grams of Kiwi provide approximately six grams of fiber. This is the amount that, according to studies, produces the beneficial effect. But that amount is not, much less, exclusive to Kiwi. We can get a similar fiber contribution in other foods that are often much cheaper. For example: A cup of cooked lentils (about 180 g) contains more than 15 grams of fiber. A ration of raspberries (125 g) provides about 8 grams of fiber. A comprehensive pasta dish (80 g dry) is around 7 grams of fiber. Two medium pears also add up to 6 grams of fiber. In this way we see that the Kiwi can work and is very healthy. But the approved benefit is not a ‘magical’ property, but the result of its fiber content, which is a nutrient present in many other foods. In your skin is where its benefits lies. Although a priori it may seem necessary to peel the entire fruit, including kiwis, Science tells us something different. In past studies it was made clear that Kiwi on your skin contains a fiber rich fountain and vitamin E, although it is recommended to wash it well before consumption. The same occurs in other types of fruits, where much of the fiber is also found in the shell that is in essence is viscous fiber. A guy that helps reduce appetite when gastric emptying and stimulating hormones that They promote satiety. The door open to advertising picaresque. The Kiwi case feels a precedent, but also reminds us of the strategies that the industry has been using for years. Regularization allows a product to contain a significant amount of a nutrient with an already approved health statement such as vitamin D, can use a slogan to promote it. He Most famous example is Actimel’s. Danone did not get the EFSA to approve specific statements for bacteria L. Casei. The solution? Enrich the product with vitamins D and B6, for which the declaration “contributes to the normal functioning of the immune system” is authorized. From there, to the famous slogan “help your defenses” there is a very short step and, above all, legal. Valuing food by a nutrient. This strategy that we have seen in the food industry leads us directly to the tendency to value food by a single function. In the case of Actimel only for its function for the immune system and now the Kiwi to go to the bathroom. In this way, a food is not valued in conjunction with all its nutrients. Eating two kiwis a day can help with constipation, but it will not serve as “antidote” if the rest of our diet is based on poor ultraprocesses in fiber. The great forgotten: the nutritional profiles. To prevent an industrial bun and saturated fats from being advertised as an iron source that helps diminish, simply because it is enriched, European legislation foresaw in 2006 The creation of … Read more

It is less powerful than its previous version but it is faster and much more refined

The Tesla Model and Performance has been revealed. He has done it with a little surprise. The new version of the Model and Performance lowers the feet to the ground to deliver a little less power and, nevertheless, to manage them to be faster in 0 to 100 km/h. But that’s not, much less, the only thing that this new version brings. Why does an electric car have less autonomy than the announcing Tesla Model and Performance Technical Card Tesla Model and Performance Measures and weight 4,790 mm long, 1,920 mm wide and 1,624 mm high. 2,890 mm of wheelbase. Weight to be confirmed.

Spotify, Disney+, Steam, YouTube applications, Netflix specifically developed. PRICE From 61,990 euros More refined at a very competitive price The tightening and tesla competition rises. The new Tesla Model and Performance is the most powerful and refined version of the company’s electric SUV that We already tried this year. The model, then, already presumed to refine the formula to offer a more mature version of the original concept. Now it seems to perfect this. The Tesla Model and Performance adopts the same formula as the Tesla Model 3 Performance. The car stays at 460 hp when it used to rise to 480 hp but is faster, lowering the acceleration 0 to 100 km/h in 3.5 seconds, two tenths faster than the outgoing model in this performance version. The maximum speed is 250 km/h. In the information sent by Tesla, the company talks about “an improved battery pack, equipped with new cells that offer a higher energy density, provides more energy without adding weight.” However, its size or capacity is not specified. Of course, an autonomy of 580 kilometers is advanced, according to WLTP cycle and an average consumption of 16.2 kWh/100 km. But the new performance is also more refined. To improve its dynamics, the electric car arrives with Achnid 2.0 forged tires of 21 inches staggered with integrated aerodynamic roofs for greater efficiency. They show the red brake tweezers. The car will also benefit from new shock absorbers and stabilizer bars that are coupled in an adaptive suspension As for design, abroad brings small novelties in its front and rear bumper that show that we are facing the most powerful version (like a small carbon fiber wing) but it is inside where it has received the most care. Now, the one who opts for the Performance version also takes the best screen, which scale until 16 inches and is offered with finer frames. The pedals are aluminum and the seats are also specific with extension on the thighs. All this with a highly competitive price. Their 61,990 euros They make it one of the most attractive options in the Power/Autonomy of the market if we take into account its size. In that price range we only have Chinese options in the market. The XPEng G7 for 56,500 euros and 476 hp of power but with a slightly lower size and the Smart #5 (of Geely) that with a price below 60,000 euros is the one that offers the most power, leaving the 500 hp, but has a higher consumption. On the contrary, if we look at the most powerful options of Hyundai Ioniq 5 or the Ford Mustang Mach E we find cars with much more power but a similar acceleration, a higher consumption and a slightly lower autonomy. All for a surcharge that goes well above at least 10,000 euros more than the version of Tesla. Photo | Tesla In Xataka | Byd wanted to have his hole in history.

The most powerful console in the world is not from Sony or Microsoft. It is from Nvidia, and costs $ 20 a month

by

The cloud game was the future. But it seems that The future resists arrivingbecause the gamers continue to prefer to go to their consoles and their pcs. And yet GeForce Nowthat has just reinforced the big. For all. To start, the guts. The GeForce Now infrastructure has been reinforced, and now the servers in charge of distributing all these games may Take advantage of the powerful RTX 5080 graphics that will undoubtedly help the fluidity of the experience be as perfect as possible. The goal has always been the same: that you do not notice that you are playing in the cloud. That hardware will of course help you get it. The update occurs two years after the last great improvement of that infrastructure, which then It was filled with the predecessors of those graphicsRTX 4080. Best experience. This hardware improvement will also allow you to enjoy streaming games to resolutions that reach 5K at 120 fps, or at 1080p at 360 fps. Users of Steam Deck Oled They can enjoy cloud game at 90 Hz (before was only 60 Hz). There is A new mode called Cinematic Quality Streaming that according to NVIDIA improves the quality of colors and graphics in general, in addition to supporting the distribution of games to 100 Mbps, when before the maximum was 75 Mbps. More data per second, better graphic quality and fluidity. Or what is the same: best experience. Steam to power. Another of the great novelties is the arrival of the option “Install -to-Play”, which actually returns an old characteristic: to be able to install games without waiting for Nvidia to “homologue” as compatible on its platform. That means we can install old games from our library and then enjoy them in the cloud, but also games that are part of the catalog of Steam Cloud Play. Many more games. According to one of the NVIDIA managers, that will suddenly allow the Geforce Now catalog will be reinforced with “2,352 games” present in Steam. This option also facilitates that future games and demos are included in the Cloud Gaming platform in Nvidia in a simple way: it will suffice that its developers activate that option by distributing them in Steam. But. There is a small disadvantage in this option, it is in the fact that the Install-To-Play games cannot be instantly executed as it happens with the “approved” games. We will have to download them and install them every time we want to enjoy them, unless we pay Nvidia a subscription to enjoy storage in the cloud for those games: three dollars per month for 200 GB, five dollars a month for 500 GB or eight dollars per month for 1 TB. Strategic alliances. To that catalog are added new alliances that further reinforce the options of the platform. Now GeForce Now can “merge” with Discord, and gamers can try new games for free directly from discord serverswithout the need to log in to GeForce Now. Epic Games is part of this agreement, and the result is striking: a user can start playing Fortnite from Discord in just a few seconds and without installing anything. At the moment the service has just taken its first steps, but Nvidia expects more and more studies to offer that possibility for players to have another alternative, especially if they are discord users. Pay $ 20 a month for renting a PC? The truth is that all these developments make Nvidia’s GeForce Now service, but once again what we “rent” is not the ability to play video games, but “a cloud pc” to enjoy them. The service does not include the games, which we will have to buy separately if we had not bought them. It is an important difference with respect to analternatives such as Xbox Game Pass Ultimate, that “video game” that does include by default a large catalog of hundreds of titles. A small cost analysis. The cost of owned by a console compared to the use of a service such as GeForce Now allows you to get an idea of whether or not to compensate for an option like this. Consoles like Xbox Series x wave PS5 They are around 600 euros, while their basic online subscription services (Xbox Game Pass Core / PS Plus) are priced at 80 euros per year. Meanwhile, Geforce Now has a fixed cost of 22 euros per month. If we take a five -year period without taking into account the cost of acquiring the games, the cost of those five years would be the following: Consoles: 1,000 euros (approximately) GeForce Now: 1,320 euros Two philosophies and both are good. But of course, we are facing two very different proposals: the consoles offer a consistent and predictable experience, but always dependent on playing where the console is. With Geforce Now we can enjoy an high -end PC experience in all types of devices – our TV, an old PC, a Steam Deck – although we depend on some external factors such as connectivity. Even so, the recurring cost is higher after that period, but as “virtual console”, its validity is clear. Here it should be remembered that GeForce Now It has striking rivals In this segment (Gamepass, Luna), which further enriches the panorama for users. The options are good.

His model is not only powerful and free, but it has cost much less

by

Openai yesterday launched its first models with open weights since 2019: GPT-Oss-120B and GPT-Oss-20B. Two reasoning systems that mark a radical change in the company’s strategy after Deepseek R1’s success At the beginning of the year. Why is it important. Openai has gone from defending the safety of closed models to recognize that “it was on the wrong side of history” with open models. The earthquake that caused Deepseek In January he forced them to rethink their entire strategy. The context. Until now, Openai had kept all its models closed since GPT-2justifying it for security reasons. But rivals as a goal with Calls And especially Chinese companies with Depseek, Qwen and Kimi They have gained ground in the open ecosystem. The turning point came when Depseek R1 showed that it was possible to create advanced reasoning models with a fraction of the cost of Americans. Sam Altman then admitted that Openai needed “finding a different open source strategy.” And here it is. In figures: The major model, GPT-Oss-120bworks at a single 80 GB GPU with just 5,100 million active parameters of its 117,000 million total. His little brother, GPT-Oss-20bit can be executed in a laptop with 16 GB of memory (although the speed seems to be very slow with such a configuration, in the absence that we can try it more thoroughly). The current situation. The Benchmarks independent They place GPT-Oss-120b with a score of 58 in the intelligence indexsurpassing O3-mini but being below O3 and O4-mini. In competitive programming tasks it reaches 2622 points in Codeforces, while Depseek R1 achieves less score with a much heavier model. In detail. Architecture uses a system of Mix of experts (Moe, Mixture of experts) that activates only a fraction of the total parameters for each consultation. This allows the 120,000 million model of parameters to activate only 4.4% in each consultation, while the 20,000 million activates 17.2%. Both models maintain chain reasoning ability without direct supervision, following the principle that visible reasoning is necessary to detect undue behaviors. Yes, but. OpenAI has not made public training data, maintaining part of the secret. Nor does it include multimodal capabilities, limited only to text. Hallucinations are significantly higher than in their own models: 49% and 53% respectively compared to 16% of O1. Between the lines. This launch responds to both Chinese competitive pressure and the new Trump administration, which has urged US companies to release more technology to “promote the global adoption of aligned with American values.” The company has worked with partners such as Orange, Snowflake and AI Sweden for real use cases, seeking to validate whether the advantages justify continuing to invest in open models. Deepen. The models are available under Apache 2.0 license on platforms such as Hugging Facewith native support in tools such as Ollama, LM Studio and Services Cloud of the main suppliers. Openai has organized a network Teaming Challenge with $ 500,000 in prizes to identify security risks. This is OpenAi’s response to his Deepseek moment: recognizing that open innovation is not only inevitable, but necessary to stay competitive in a panorama where cost and accessibility matter as much as performance.

China already thinks about strategies to neutralize Elon Musk’s Starlink satellites. Your plan: submarines and powerful lasers

by

Chinese scientists have developed strategies to neutralize the Starlink Satellite Network of Elon Musk, which Beijing considers a military threat. According to the medium The Independentamong the proposed measures are furtive submarines equipped with spatial lasers, attack satellites with ionic propellants and sabotage of the supply chain. An analysis of 64 academic articles published in Chinese magazines reveals the concern of the Asian country for Spacex’s spatial domain. Why worries so much Starlink. The constellation of satellites carried out by Elon Musk controls two thirds of all active satellites in the world, with more than 8,000 operational units. Its ability to provide fast and cheap connectivity anywhere on the planet, including remote areas, makes it a strategic tool. Chinese researchers They fear that the United States will use it as a military weapon after checking its effectiveness in Ukraine, where facilitated the communications of the Ukrainian army and the control of combat drones. What China poses. Several Chinese researchers and scientists have proposed multiple approaches To counteract Starlink. Engineers of the Popular Liberation Army suggest creating a fleet of spy satellites that follow those of Musk, collecting signals and using corrosive materials to damage their batteries. Other researchers propose optical telescopes to monitor the network, generation of false objectives through Deepfakes and the use of powerful lasers to burn equipment. They have also identified vulnerabilities in the Spacex supply chain, which has more than 140 main suppliers. They will not only be countermeasted. Beijing is not limited to planning countermeasures: it is building its own alternative. In 2021 the Chinese state company created SATNET To develop Guowang, a military megaconstellation that already has 60 operational satellites of the 13,000 planned. In parallel, The Qianfan companysupported by the Shanghai government, has launched 90 satellites of the planned 15,000 and already competes for contracts in Brazil, Kazakhstan, Malaysia and several African countries. The geopolitical context. The Ukraine War marked a turning point in Starlink’s global perception. The conflict showed that the control of satellite communications can tip the balance. What worries China is that a single man like Musk can also interrupt critical services. The medium raises as an example that time in which the tycoon He denied his coverage For a Ukrainian counterattack in Crimea. This dependence on private actors He has not only alarmed Chinabut also to traditional allies of the United States such as the European Union, which invests billions in Your own Iris2 constellation. What comes now. The overwhelming domain of Starlink in space, which already operates in more than 140 countries and only has dead areas in North Korea, Iran and China, has triggered a undercover space race. While Amazon develops her Project Kuiper With just 78 satellites, China accelerate your programs To reduce Musk’s advantage. Interestingly, one of the papers of Chinese researchers simply had the following title: “Be careful with Starlink”. It is clear that space control will be an advantage for armed conflicts and commercial wars that are being released.
