A huge fuel tank has fallen from heaven in Argentina. And we already have suspicious: a Chinese rocket

by

The afternoon is almost always quiet in the small Chaco town of Puerto Tirol, north of Argentina. On Thursday, that tranquility was interrupted by an object fallen from heaven. He had appeared on a rural property whose owner did not hesitate to call the police. The police cordoned off the area waiting for firefighters. All the investigations are already made on the Internet. What is known. The object measures 1.70 meters long by 1.20 meters in diameter. It is metallic, has a cylindrical shape and is covered with carbon fiber or a similar compound material, so it is surely a pressurized propellant tank, a piece of the space rockets known as Composite Overwrapped Pressure Vessel (COPV). When a satellite or a rocket re -enters the atmosphere, most of its body is burned by pressure. These containers, on the other hand, are designed to support very high pressures, so it is not strange that they survive intact. Or judging by the photos, somewhat chamuscados and frayed. What is suspected. The first identification came from the hand of the Caribbean Astronomy Society (SAC) in A Facebook post. They confirmed that it looks like a piece of space vehicle, specifically a COPV. And they pointed out that, of the most recent releases, the main candidate is a Chinese rocket released the day before. The analysis of the trajectory seems to confirm suspicions. The astrophysic and renowned Jonathan McDowell satellite tracker He corroborated this hypothesisstating that the object is “probably” the tank of the fourth stage of a Chinese jielong-3 rocket. From China to Chaco. The private company China Rocket had launched on Wednesday the eighth mission of its Jielong-3 rocket. The Y8 mission took off From a maritime platform At 07:56 UTC to put 12 satellites of the Geely Future Mobility constellation in orbit, a positioning and communications service of the Chinese automotive giant Geely. After displaying the satellites, the fourth stage of the rocket continued to orbit the earth until 9:00 UTC of the next day, when It was sighted disintegrated in the sky 15 kilometers from Puerto Tyrol. Most likely, it will not be completely burned and the deposit survived the fall. A questionable history. China has earned in recent years. The most notorious case is that of the CZ-5B state rocket, whose central stage of more than 20 tons is designed to reach the orbit and then fall to the earth unpredictably within a period of days or weeks. The reality is that this behavior is changing, and both state and private companies are actively providing their rockets on the ability to actively extend, keeping some fuel and after deploying satellites. The problem is not that. But the space garbage, and that is that the Earth’s orbit has become a landfill. There are all kinds of dead satellites and rockets in the terrestrial orbit that gradually approach the earth due to atmospheric braking. With the rise of satellite megaconstellations, every day they re -enter the atmosphere an average of three large pieces of space garbage. And in this case they do it without any control. As a result, incidents in inhabited areas are increasingly frequent. In March 2024, a fragment of a battery pallet discarded from the International Space Station crossed the roof of a house. In January 2025, A half ton ring He appeared in a town in Kenya. In February, several fragments of a spacex rocket They fell near the city of Poland. The Earth is very large and mostly depopulated or covered with water, but it is a matter of time that something happens. Therefore, space agencies such as ESA They are promoting a commitment of “zero waste” to harden the regulations of their own missions. It is necessary, yes, a global consensus.

We thought that sleeping in 90 -minute blocks improved rest and energy when you woke up. Science has its doubts

by

As so many other viral trends In social networks, in recent years a seemingly simple formula has run like gunpowder for improve nighttime rest and wake up fresh like a lettuce: Calculate the dream in 90 -minute blocks To wake up just when one ends those blocks. This technique ensures that, when you wake up just when a complete sleep cycle ends, people They will feel more rested and with greater energy to face the day. However, scientific evidence questions the reliability of this method. The myth of exact 90 minutes cycles A survey of 2024 made by the American Academy of Sleep Medicine He revealed that almost one in ten American adults (9%) had tried this technique to determine what time they had to go to bed and wake up and have even been created Online calculators To make this calculation easier. The basis of this technique is based on Natural sleep cycles that are part of the set of cycles that regulate our body known as Circadian cycles. These cycles are the ones that determine the time of sleeping, of waking up, of eating, etc. According to this technique, a person who wants to wake up at 7:00 in the morning should go to sleep at 22:00 to complete six full -minute sleep cycles, or 23:30 to complete five sleep cycles. The concept is based on the idea that awakening at the end of a complete cycle, in phase V or REM, When the dream is lighterwould avoid the feeling of morning stun that occurs when we wake up in the middle of one of these cycles. Sleep cycles were first identified in the 1950s, when researchers They discovered These patterns called Ultradian cycles. During the night, the alternate brain between different phases: light sleep, deep sleep and REM sleep (characterized by the most intense dreams). Dr. Fouzia Siddiqui, Medical Director of Sentara Rockingham Memorial Sleep Center, explained in Popular Science that each of these phases fulfills specific functions for physical and mental recovery. However, the popularization of this scientific knowledge has led to excessive simplifications that They do not reflect the real complexity of human sleep. The most important of them: that the sleep cycles last exactly 90 minutes. That is the biggest problem of this theory. Scientific reality dismantles promises Recent studies They have shown that the duration of sleep cycles is not a constant but a variable. That is, its duration varies depending on each personand even the same person You can record more or less long cycless during the same night or vary according to the day. An investigation He analyzed more than 16,000 nights of sleep in 573 different people found that the median duration of sleep cycles was not 90 minutes but 110 minutes, with 75% of the cycles ranging between 95 and 130 minutes. Another study based on 2,312 nights of polysomnography data determined that the average duration of the cycles was 116.9 minuteswith a standard deviation of 39.7 minutes. In other words, establishing the 90 minutes as a basis for calculating sleep cycles not only is not an inaccuracy, but in practice it can be counterproductive since there is also the risk of interrupting the sleep cycle before it ends. Dr. Andrea Matsumura, specialist in Sleep Medicine and founder of Sleep Goddesss Method, said In the article of Popular Science that “factors such as stress, Alcoholdiseases or even bedtime, impact on the sleep cycle, so this method does not really guarantee that you wake up less stunned. “ In addition, the studies identified that as night progresses, sleep cycles They tend to elong in a natural wayso that the former can last between 70 and 100 minutes, while the later range between 90 and 120 minutes. Making it impossible to predict at what point in the cycle You will find yourself when it is time to wake up. On the other hand, in a standard sleep session of a healthy person, it is very unlikely be ahead of a deep phase of sleep since phase 3 of sleep, the deepest and repairinglasts between 20 and 40 minutes and usually occurs in the middle of the sleep session, and then move back to phase 2 which is a relaxing but lighter dream. Therefore, unless you are sleeping very few hoursthe awakening occurs from that lighter phase, and not from a deep phase as the 90 -minute block theory supports, which would leave a greater feeling of stunning. That is, this theory is based on two real facts: that awakening from phase 3 leaves you more stunned and that sleep cycles last around 90 minutes, to set up an alleged infallible technique to wake up as a rosto. The problem is that sleep It is not an exact science And the only thing that really works is Ensure the Descaso Hours that the body needs … and there are not even certainties about How long is needed.

While industrial production collapses in the European Union, in Switzerland is triggered. And it is an energy issue

by

In the midst of the European energy storm, Switzerland seems to live in a bubble of prosperity. In a recent publicationthe geopolitical analyst Velina Tchakarova showed how the Swiss industry continues to grow in front of the European Union. And the data does not deceive anyone: in the first quarter of this year the industrial production of the Helvetic increased 8.5% year -on -yearwhile in Germany recorded last June A 1.9%collapse, the worst data in years. The contrast is even more evident in the long term: since 2011, Swiss industrial production It has grown almost 40%in front of the German stagnation. The Swiss road. True to its neutrality, but knowing how to position itself, the Swiss industry is dominated by sectors of high added value and low relative energy consumption, like pharmaceuticals and biotechnology. But here is the most revealing: that low energy consumption is not only efficiency, but also outsourcing (a sophisticated strategy of Green offshoring). An EBP consultant study for the Federal Environmental Office (BAFU) shows that two thirds of the environmental footprint of Switzerland They are generated outside their borders. The report Umwelt Schweiz 2022 Confirm this pattern: the country reduces its internal impact at the expense of moving it abroad. There are different examples that illustrate it well: the Roche company announced in May A new biopharmaceutical plant in Shanghai, the Lonza company operating in Guangzhou Or, the most striking case, Siegfried managing a global network with headquarters in different countries that allows you to distribute phases of the chain outside the Helvetic territory. Together, these movements illustrate how the Swiss industrial “miracle” retains the added value at home while displacing the most polluting and expensive part abroad. To this is added an electrical system less vulnerable to gas: the Hydroelectricity and the nuclear They represent a good part of their mix. The Labyrinth of the EU. At this time you are going through an industrial decline: Eurostat reported that in June the production fell 1.0% in the EU as a whole and 1.3% in the eurozone. The setback It was coming last yearwhen the manufacturing volume was 2% lower than in 2022. And Ing Think analysts They warn that European industrial production It remains 5% below two years ago, a prolonged stagnation signal. To this fall is added a perfect storm: high energy costsCO₂ and an internal debate about its energy model. France, With a reactor -based systemleads the block that defends nuclear energy as a backbone of the transition. Spain and Portugal, with solar and wind abundance, demand otherwise: more interconnections and networks To take advantage of renewable surplus. In addition, it is added The tireless search by the EU of looking for another output to stock up that it is not Russia in terms of gas. While Switzerland transfers its heaviest loads to Asia, Europe is enclosed in its own rules, paying CO₂ rights that further increase its energy intensive industries. Switzerland outsourizes, Europe internalizes. Switzerland harvest added value, Europe assumes added costs. The awkward contrast. Here the paradox emerges. Switzerland exhibits an expansion industry, favorable environmental statistics and a more stable electricity supply. Everything seems to indicate that it has found the perfect formula to prosper in the midst of European chaos. For its part, the European Union is paying the price If pioneer: its factories face much higher energy costs, their energy intensive industries lose competitiveness and their governments carry the pressure of meet strict climatic objectives. But Swiss success relies on a small print. The report itself Umwelt Schweiz 2022 He admits that two thirds of the country’s environmental footprint are generated outside their borders. That is, Switzerland retains at home the added value of its pharmaceutical and technological industry, while the energy cost and pollution are transferred to other places. That apparently virtuous model implies a strategic risk: to depend on global supply chains and expose themselves to political vulnerabilities in Asia. In climatic terms, the question is inevitable: are global emissions really reduced when Switzerland “is cleaned” at the cost of others getting more? Or, in other words, isn’t its industrial miracle with another way to outsource the environmental invoice? Forecasts On paper, Switzerland seems greener and more prosperous. But the true story is told in the chimneys of China and in the closed factories of Germany. The Helvetic miracle works, to a large extent, because the energy and climatic invoice is paid by others. While industrial production collapses in the European Union, in Switzerland is triggered. However, that balance, sustained in global chains and in others, could be broken when geopolitics tightens. The real unknown is not how much the Swiss miracle can last, but who is willing to pay his invoice.

Intel has been manufacturing chips for decades only for her. His only salvation is to make chips for all others

by

Let’s make a trip to the past. The year is 1997 and Steve Jobs has just returned to Applebut the state of the company is terrible and its future, uncertain. To try to save her Apple began to look for strategic alliances, and that was when she announced an absolutely unusual with Microsoft. Bill Gates’s company would invest 150 million dollars in Apple And both would collaborate on several fronts. That unique agreement seemed impossible. Both companies were large rivals, but the truth is that both won with that alliance. Now it seems that we could live an analogous situation with two other companies that are also large rivals. On the one hand Intel, which is as low as Apple was in 1997. On the other TSMC, which dominates in the semiconductor market like Microsoft did it in the software then. According to The Wall Street Journalboth companies are negotiating a possible alliance that is certainly surprising, but has very interesting ramifications. If TSMC helps Intel’s “salvation”, That will give you an advantageous position in future agreements with the US government. This government is now the owner of 10% of Intel’s shares, and for better or worse to get along with Intel, it means getting along with the administration. Taking into account the current policy that practically forces to manufacture chips and components in the US to get rid of tariffs, that potential alliance becomes profitable. Not just that. The agreement also favors TSMC interests when avoiding possible antitrust. How is it going to be a monopoly when you are helping a competitor not go to pique? As They demonstrated Apple and Microsoft, eliminating competition is not the only way to win the game. A promising transition The Historical crisis For which Intel has been going through his new CEO, Lip-Bu Tan, to make very difficult decisions. The mass layoffs They are part of that strategy, but the company has also attended a deep restructuring that It is “chopping”. But there is even more. In fact, Intel’s strategy seems to be recognized and Accept the failure of the era of “exclusive chip”. The firm has admitted that manufacturing by and for it had no route, and now wants to focus on a business model on which it is A chips factory for third parties. That is exactly what has placed TSMC where it is. If the alliance with TSMC is completed, a unique strategy would be confirmed by Intel in which in a few weeks we have lived a unique opening to alliances of all kinds and condition: SoftBank injected 2,000 million dollars USA bought 10% of Intel for 8,900 million dollars Nvidia invested 5,000 million dollars Apple is a candidate for a collaboration agreement And now TSMC could also follow those steps All these steps certainly open an escape for an Intel that seemed to be against the strings. If such alliances fruit, Intel will only lack his two great future objectives. The first, fulfill your promises With the 14th node to which everything has opted. The second, Get customers For that node. And that is where those agreements can be very useful. Image | Intel In Xataka | Intel has confirmed that the 20A node will be skipped to reduce expenses.

One thing is to knock down drones, and another very different and dangerous Russian airplanes. The second option is winning too many followers

by

The repeated incursions Russian aerials in NATO territory They have triggered a diplomatic and military escalation that places the Atlantic Alliance against one of its greatest dilemmas since the beginning of the war in Ukraine. First They were dronesand then several MIG-31 fighters next to an IL-20M recognition plane in the Baltic without flight plan. The perception, increasingly widespread in Europe, is very dangerous: the Kremlin seeks to test The allied disposition to respond firmly. The internal debate. They remembered In politician that incidents have caused urgent consultations Under article 4 of the North Atlantic Treaty, a rarely invoked mechanism that reflects the seriousness of the situation. Estonios, Poles and Czechs have claimed Hard responsesincluding the possibility of demolishing Russian aircraft in future violations. The Czech President Peta Pavel, former NATO Military High Command, affirmed that Moscow must face “military consequences.” In Tallin, Foreign Minister Margus Tsahkna insisted in which to defend the sky of Estonia is equivalent to defending that of the entire alliance. Instead, figures such as German Defense Minister Boris Pistorius and Italian Prime Minister Giorgia Meloni They alert the risk To fall into the “climbing trap” lying by Putin, aware that a demolition could be interpreted as Casus Belli. Parallel messages. The president of the European Commission, Ursula von der Leyen, adopted An unusually overwhelming tone When declaring That “every centimeter of the territory” must be protected and that, after clear warnings, the option of folding an intruder plane “is on the table.” His words resonated With Trump’sthat in the UN General Assembly he affirmed that the “yes” allies should shoot against Russian airplanes if they enter their airspace. The support of the US President was held in Warsaw, where Minister Radosław Sikorski He replied with a laconic “Roger That”. The coincidence of speeches between Brussels and Washington (although von der Leyen has no direct military authority) transmits to Moscow that there is an emerging consensus in favor of harden the rules of the game. A 12 -minute pulse. The most symbolic case was the starring By three mig-31 Russians intercepted by two Italian F-35 in Estonia. During more than ten minutesRussian fighters remained within NATO airspace, an unprecedented duration. The Italians performed the standard interception maneuvers and, surprisingly, the Russian pilots responded With a friendly gesturegreeting from the cabin. Although the meeting concluded without shots, in Tallin and in Brussels a immediate debate: Why didn’t it acted with the same forcefulness as Türkiye in 2015When did a Russian plane tear down in just 17 seconds after a border rape? The difference illustrates the current caution of NATO, trapped between the need to show determination and the fear of an incident that disappoints an uncontrollable escalation. Hybrid ambiguity. The Russian authorities They have denied Deliberate violations and attribute incidents to errors, but at the same time suggest that they respond to Ukrainian attacks in Crimea, which is equivalent to accusing NATO of direct complicity. European diplomats who met with Kremlin say that the Russian delegation He took exhaustive noteswhich reinforces the impression that Moscow uses these incursions as calculated pressure tools. Experts like the Lithuanian president Gypsyėda They point that Russia “is testing our preparation and our solidarity.” In this sense, aerial incursions are part of a hybrid repertoire that includes espionage, cyber attacks, disinformation campaigns and symbolic maneuvers in the Baltic borders, such as balloons and buoys displaced in border rivers. The strategic dilemma. NATO has reinforced surveillance with the operation Eastern Sentry and maintains Eurofighter, F-16 and F-35 fighters deployed in the region, but still lacks clear and homogeneous confrontation rules. The ultimate decision to shoot falls to governments nationals that provide airplanes, which generates a mosaic of interpretations and possible “caveats” that could leave countries as Estonia in vulnerable situation. Meanwhile, Tallin has decided to increase its military expenditure to an average 5.4% of GDP Annual until 2029, a record figure in the alliance, although without acquiring its own fighters, which maintains the dependence of the ally air coverage. On the edge of the red line. In short, the Crossing speeches reflects a paradox: while Voices increase In favor of demolition as immediate response to airspace violations, other leaders remember that Putin could be looking for that incident to legitimize a victimization and victimization narrative Sow divisions internal in NATO. If you want, the situation recalls that the defense of the European sky is no longer a mere exercise of routine interceptions, but A critical front of the ongoing hybrid war. At stake, in addition, there is not only the security of Estonia or Poland, but the credibility of the alliance as guarantor that every centimeter of its territory, in the words of Von der Leyen itself, will continue being inviolable.

Gabrielle is at the doors

by

He Hurricane Gabrielle It has become what the NHC (National Hurricane Center), the US agency dedicated to the surveillance of tropical storms, calls a post-tropical cyclone. Right now the storm The Azores Archipelago crossesbut the models indicate that their arrival to the continent will be through the Iberian Peninsula. Any Sunday. Meteorological forecasts indicate that former Gabrielle The Peninsula will arrive on Sundaytouching land in Portugal. Of course, its effects could begin to notice hours before this arrival, even during the Saturday afternoon. As explained by the State Meteorology Agency (Aemet), Gabrielle will already become an extropest storm. For now, uncertainty prevails regarding how the arrival of the storm will be, but we can expect instability to affect a good part of the Southwest Peninsular during the weekend. Gabrielle’s itinerary. Gabrielle began his journey as a tropical storm in the central area of ​​the Atlantic and took northwest direction until he approached Bermuda. Before reaching the archipelago, the storm intensified until reaching the hurricane category, and then Make a turn of about 90º and put towards the northwest and then in the direction of the Peninsula. The models indicate that Gabrielle’s most likely route will take the storm to touch the ground near Lisbon During the early hours of Sunday. The route would continue to head southeast, in the direction of the Gulf of Cádiz. “High uncertainty. ” As Aemet points out, there is a “high uncertainty” not only with respect to the trace of the storm, also with respect to its possible evolution. The agency for now has issued some yellow notices by risk of rains in Western Andalusia, where accumulated 30 mm are expected in six hours. You can expect the notices to change as the information will be more accurate. What they tell us Aemet’s forecasts We can expect abundant cloudiness. The agency indicates that the possibility of rainfall during Sunday will extend throughout practically the entire territory, although it is in the southwest (also in the Cantabrian and part of the Mediterranean coast) where they are more likely. With respect to the winds, large gales are not expected for now due to the weakening of the cyclone. Aemet speaks of “moderate winds in the northwest coastlines, with intervals of strong and Possible very strong gustsoccasionally moderate in the Gulf of Cádiz, Balearic Islands and areas of the Peninsular Northwest Third ”. Behind Gabrielle, Humberto. While we leave doubts about what Gabrielle will hold, the tropical storm Humberto could take a similar route. For now this formation advances west through the waters of the Atlantic. However, forecasts indicate that the storm will turn north before touching land in North America. This could put Humberto on the course of the east towards the second half of next week. There is still much for it for what we will have to wait to know the evolution of this potential hurricane and the real possibilities that their remnants reach us as those of Gabrielle are.

The danger of using AI chatbots for everything is real: MIT has discovered the “cognitive debt”

by

A MIT study He has shown that chatgpt and similar tools generate what they call “cognitive debt”: students who resort to them for total use end up writing better, but thinking worse. Why is it important. The study contradicts the belief that AI is like a calculator: a simple support that frees us for more complex reasoning. Actually, these tools can atrophy the brain connections that build critical thinking. The facts. 54 university students have spent months writing essays, divided into three groups: Grupo LLM, which used Chatgpt. Search motor group, which used Google. And group Solo-Cerebro, without external tools. The researchers measured their neuronal activity with electroencephalograms and the results have been overwhelming: those who used a neuronal connectivity systematically lower in all frequency bands. Compared to the group that only used its brain, there was a lower activation in key networks that connect parietal, temporal and frontal regions, fundamental for attention, memory and semantic processing. In Xataka 81% of interviewers suspected the traps with AI in interviews: 31% have confirmed it without a doubt and they have put a brake The contrast. The essays generated with AI received better notes, both from teachers and evaluating algorithms. But their authors remembered worse what they had written minutes before and felt a minor authorship about their texts. When they forced the usual users to write without help, their brain patterns showed that dependence on external support. They had lost ability to reactivate the necessary neural networks to write independently. How to walk without support after years doing it with crutches. Yes, but. The students who learned to write without ia and then used it for the first time maintained their engagement neuronal They even showed better memory and reactivation of broad brain areas. The key difference: You need to know how to think before you can think with machines. In perspective. This pattern replicates what we see in other professions: The subway driver who feels alienated because the train drives alone. Translators turned into machine editors. 3D creatives that only retouch what the AI ​​generates. {“Videid”: “X9R6K72”, “Autoplay”: False, “Title”: “Chatgpt Pulse”, “Tag”: “Technology”, “Duration”: “67”} The threat. The study also analyzed university students who already had developed writing skills. The effects could be more severe in adolescents who are still building these cognitive abilities. As a Dartmouth teacher said: we run the risk of creating “an educated generation with AI shortcuts” that lacks independent thinking skills. And now what. The sequence matters more than technology. First, you learn to think. Then, you learn to think with machines. The brain needs to build those Neuronal highways before being able to delegate selectively in AI. The study concludes that educational interventions should “combine the assistance of AI tools with learning phases without tools” to optimize both immediate skill and long -term neuronal development.

This is the new treatment approved in the USA

by

Age usually takes its toll and presbyopia is one of the main factors responsible for it. Now a few drops can change this. Approved in the US. The drug regulatory agency in the United States, the FDA (Food and Drug Administration), approved a few weeks ago A new treatment against presound. It is a solution for ophthalmic use, a few eye drops, aceclidin, which applied daily can help reduce the effects of this disorder for about ten hours. A degenerative disorder. The presbyopy is an ocular disorder associated with aging. Over time, our eyes gradually lose their ability to focus close objects, which hinders some of the tasks of our day to day, such as reading. The presbyopy It usually begins to demonstrate between the age of 40 and 45, although its progress usually touches the roof when we turn 65. Today there are different tools to fight the presbyce, which include the use of lenses or surgery. Acechlidin. The treatment is based on aceclidin, a compound that had already been proposed in ocular health In other contexts, such as the treatment of some types of glaucoma. The compound acts by contracting the Iris sphincter musclethe person in charge of contracting the pupil, and does so, according to the developers of the new treatment, with a “minimum” stimulation of the ciliary muscle, another eye muscle, is located outside the Iris. What the treatment is achieved is a stenopic effect by making the pupil contract below the two millimeters. This effect is the one that works wings cameras Pinhole Or Stenopic, which gives them a wide focal range, even losing sharpness as a consequence of diffraction. Clinical trials. According to They explain from Lenz Therapeuticsthe company responsible for the new treatment, the approval of the FDA comes after a series of clinical trials, controlled and randomized double -blind studies, the Clarity 1, 2 and 3 trials. Can we check it? For now the treatment is approved in the United States but not in the European Union. In fact, despite having been approved in the United States, the drug is not yet available in the North American country: the responsible pharmaceutical company has put October as the month of launching the new drug.

France has tried by all means that CAF does not take “the contract of the century” of the Belgian trains. There is good news

by

The contract continues. That is what the Belgian responsible for one of the country’s greatest tenders have said. The so -called “Century Contract” will therefore fall on CAF, the great Spanish rail giant. The Spanish company will be in charge of providing trains to the “Belgian Renfe”. Refused. The State Council of Belgium has spoken. And what has decided is that it rejects the last resort that Alstom had presented in the award contest to provide the CNS (the Belgian Renfe) of a huge battery of trains to modernize much of the fleet. In The mail They detail that the Belgian State Council had already rejected a resource for Siemens last week and now has been dismissed that of Alstom. The process has been especially long and complex with numerous resources presented, comings and goings and reconfirmations. “The contract of the century”. Given the enormous volume of money that will move this contract, it does not seem that the famous denomination of “the contract of the century” is left great. To start, the investment will be 1,695 million euros but if the deadlines and volume of deliveries are met, CAF could receive up to 3.4 billion euros. The amount will be paid for The supply of 500 trains Automotores including three car models with battery hybrid propulsion that will have the task of replacing the old diesel locomotives in those roads that have not yet been electrified. With the rejection of the latest resources, it only remains to negotiate the last details and sign the greatest contract in the history of CAF. Long and complex. Getting with this contract has not been simple for the Spanish company. At the beginning of the year, Alstom and Siemens resorted to the award of CAF to CAF, claiming that the motivations for it were not transparent enough. In April, a Belgian court recommended suspending the contest. During that time, Alstom took the opportunity to press by pointing out that his proposal was better because they have a plant on Belgian soil, emphasizing that the decision to take out this contract would harm the citizens themselves because they were not betting on local employment as a decisive factor. The process, however, continued. However, CAF has had to wait for the Belgian authorities to definitely reject the resource of Siemens and a second resource by emergency presented by Alstom, who insisted again on a supposed lack of transparency. Israel. During the last bars of all this bureaucratic framework, various voices rose to question the award of CAF. They defended that a company that was associated with the Israeli Shapir could not be hired to build and expand the red and green lines of the Light Jerusalem Rail. The project is problematic because it will be built on illegal Israeli settlements. That has caused the Basque company to have been indicated in an official UN report as one of the companies that take revenues from the country’s antipalestine policy. They specify that with this type of works these illegal settlements are helped. 500 million euros. That is what is estimated to take coffee If the Israeli project goes ahead. This is valued at 1.8 billion euros to lift 27 kilometers of roads and 50 new stations. With them we want to connect the West Bank settlements with those of West Jerusalem. The business for CAF does not remain alone in the construction of this light meter. It is also about to decide when it will participate in the management of the lines. At the moment, it is being assessed that its involvement is maintained between 15 and 25 years once between operation. CAF shields that the award of the contract is prior to the Israeli invasion of Palestine. Do not get into. At least that is what they say from SCNB. Appealed by up to four associations that rejected that CAF received this contest for its involvement with the project in the West Bank and Jerusalem, the Belgian operator has responded that it cannot “determine the foreign or commercial policy of the companies involved,” they collect in The mail. Its position is contrary to other companies in the sector. The Norwegian sovereign fund, for example, has retired its investments in Shapir (the partner of CAF in the Israeli project) for the genocide committed in Gaza and the Manager Storeband also took CA from its portfolio for its involvement. The Catalan company Comsa was also part of the consortium that had gained the award of the blue line of the tram to Jerusalem but In 2024 he retired from the project and The Basque Siner announced that it will not serve steel to Israeli companies.
