The AI is putting the US power grid in trouble. And Google has already taken a measure that shows the magnitude of the problem

by

Google data centers work 24/7, processing searches, videos and now also AI models. But not everything can grow at the same pace. In several areas of the United States, electricity begin to notice the pressure: Energy demand is accelerated and In some places already exceed capacity forecasts. Given that scenario, Google moves: It will reduce the consumption of your data centers when there are peaks, prioritizing the essential and postponing what you can expect. The novelty is the focus: Machine Learning charges. Artificial intelligence progresses. The electricity grid notice. The expansion of AI is going so fast that companies receive more connection requests than they can meet in certain areas. The consequence is no longer only technique: there is an energy restriction that conditions the deployment. It’s not about turning off machines, but moving loads. The “demand response“It consists of adapting consumption to what the network can supply at all times. In practice: displace or reduce non -urgent loads – like the processing of programmable videos or tasks – outside critical hours. It is a tool used in intensive industries and cryptocurrency mining, now applied to data centers with AI. The system has clear limits. This type of flexibility is not applicable in all centers or in all situations. Google recognizes it clearly: there are services that you just can’t expect. Platforms such as Search, Maps or the cloud for critical sectors – such as health or emergencies – require continuous availability, without margin for load settings. There are no “non -urgent” tasks that can be postponed. Therefore, although the response to demand is a valuable tool, its implementation will remain partial and selective. It requires planning, previous agreements and an infrastructure designed to absorb that type of reorganization. Not all centers can do it. But where it is possible, it becomes a real way to relieve pressure on the network without compromising the essential. There is already experience, and now. It is not theory. Google tested this flexibility With the public electric of Omaha and reduced demand associated with Machine Learning in three network events last year. The next step are formal agreements with Indiana Michigan Power (Fort Wayne) and with Tennessee Valley Authority: in Indiana it will be integrated from the beginning of the new center, and in Tennessee it will be applied coordinated with the operator. From experiment to strategy. What began as a pilot becomes operational policy: Managing demand flexible helps stabilize the network and accelerates the connection of large loads without waiting for new lines or centrals. It is not a magical solution, but it wins time while the infrastructure is reinforced.

It is called 815a and its power lies in the place from which you can watch

by

That China is determined to intensify its operations Navales is out of any doubt. Not only is it raising a fleet of aircraft carrier that you have never had, its operations with Combined exercises in nearby waters (And not so much) They attest to that explicit demonstration of their global ambition. Now, in addition, you have to add the last demonstration of Beijing force: a gigantic detective. The new era of naval espionage. Yes, spy ships Type 815a They have become a fundamental piece of Chinese maritime strategy. His recurring presence in disputed waters and in international exercises reflects Beijing’s determination to project power and collect strategic intelligence persistently. In fact, the recent case of tianwangxingintercepted by the Philippines coast guard within the exclusive economic zone of Manila while escorting a destroyer and a Chinese coast guard, symbolizes this new stage of aggressive surveillance. And more. The remarkable thing is that the operation coincided with the Aerreo Exercise Cope Thunderin which the United States first deployed F-35 furtive fighters In the Philippines, which reveals how the Chinese Navy guides its naval espionage to capture in real time the military capabilities of Washington and its allies in the Pacific. Expanding float. The origin of 815a dates back to late ninetiesWhen China sought technological independence in naval intelligence. The first ship, Beijixingwas the first totally designed and built in the country, opening a series that since 2010 has multiplied with the arrival of more advanced variants. With dimensions of 130 meters of length and 6,000 tons of displacement, these boats count With diesel engines of great autonomy capable of sustaining prolonged missions thousands of kilometers from its bases. By incorporating furtive techniques into the helmet, closed masts and absorbent coatings, they manage to reduce their radar firm. The Type 815a One More Thing. However, the distinctive feature of the class are its bulky radomes, which protect electronic intelligence systems (ELINT), of communications (Comint) and radars capable of capturing and analyzing signals in wide ranges of the electromagnetic spectrum. Detection capabilities. What really makes these ships A complete map of the adversary military environment. As? They can identify radar emissions of aircrafts and destroyers to more than 700 kilometersand even to 1,200 according to some reports, in addition to tracking 1,500 kilometers. The information collected is transmitted in real time through connected redundant satellite links to the Beidou systemallowing immediate integration with anti -men’s ballistic missiles like DF-26 or the Hypersonic YJ-21. In this way, the presence of a single 815a in the vicinity of a multinational naval exercise is equivalent to placing a whole fleet under the sight of Chinese attack systems. From sea to space. Plus: The new recognition ship Liaowang-1 He has taken this doctrine even further. Its sensors, with detection capacity of up to 6,000 kilometers and satellite monitoring in geostationary orbit, expand the Chinese surveillance field to space. With six poachers endowed with multiband sensors, neural networks algorithms to classify targets with 95% precision Even under electromagnetic interference, and Aesa radar modules based on gallium nitride (ten times more powerful than previous generations), the Liaowang-1 constitutes a jump that S sItúa China at advantage against US equivalents such as Howard O. Lorenzen. This not only strengthens Chinese naval deterrence, but opens a spectrum of early control and warning operations that transcends the maritime surface. Surveillance strategy. The constant practice of sending An 815a to monitor international maneuvers (from RIMPAC In Hawaii Even Talisman Sabre In Australia) it has become a routine tactic. The mere entry of one of these ships in the area of an exercise Activate the network Chinese satellite, which transforms a routine deployment into a real -time attack simulation. For United States allies, this presence means having to Limit radar emissions and communications, which reduces the effectiveness of joint maneuvers. In other words: in an open conflict scenario, the shadow of an 815a would imply that the position of each enemy ship would already be incorporated in the Chinese missile guidance calculations. Strategic implications. Beyond electronic war and classic naval espionage, 815a constitutes A central node in the concept of Chinese multidominium warcapable of linking the surface of the sea, airspace and terrestrial orbit. Its visibility, however, also represents a weakness, since its radomes make it an easily identifiable target. Analysts expect future variants incorporate antennas Conformal integrated into the helmet, increasing its stealth and reducing vulnerabilities. The inclusion of command systems based on artificial intelligence is also anticipated to coordinate swarms of drones and electronic attacks autonomously, expanding the radius of action of Chinese intelligence beyond physical. Silent threat. In short, the 815a shipswith its low profile in terms of weapons and its enormous reach in matters of intelligence, they embody the new paradigm of the Naval War: it is not the visible fire power that defines superiority, but the ability to collectprocess and exploit data in real time to guide long -range weapons. China has turned these platforms into strategic multipliers that guarantee that any American attack group in the Indo-Pacific is under constant observation and, potentially, under direct threat of its missile arsenal. In them, Beijing’s transition is condensed from being a regional vigilant power to Aspiring superpower With the ability to control the sea, air and outer space.

How to create a Power Point presentation with artificial intelligence

by

Let’s explain How to create a Power Point presentation with artificial intelligence. In this way, you can create your slides quickly and easier, without having to have knowledge to design them manually. We are going to start the article with some previous tips that you must take into account before starting to create your slides. And then, we will tell you two or three ways to do it using different free tools. Before starting, some tips Before putting your PowerPoint slide designs, you must be clear of the presentation you are going to create. You will have to know the general idea of what you mean, the ideas you want to convey, and the tone you want to do with. Secondly, you must also Be clear about what you are going to put in each vignette that you generate for your presentation. It is not enough to know the objective and what you want to convey, you also have to order the ideas and plan the basic structure. Think of the classic introduction, development and conclusion schemes. An additional advice is that You can also use AI for planning. You can tell a generative AI as Chatgptalthough you can also use COPILOT, Deepseek, Gemini or similar that you want to make a presentation on a subject, and that helps you organize ideas on different slides telling you what you can put in each of them. It is also important Be clear about visual style What do you want to use. Think if you want a formal, creative, academic presentation or with a concrete personality, and then think of the colors or the type of images you want to use, so that you can then go to the AI in the creation process and that each vignette is not completely different from the previous one. Make the slides in chatgpt One of the things you can do is compose the presentation through images created with chatgpt or others capable of generating images. For example, you can use a Prompt like this: “I want you to create a PowerPoint slide. In it, the presentation title has to appear, which is” Xataka Basics “. Below, as a subtitle put” How to make your PowerPoint presentation with AI. “The slide must have the image of the face of a robot to one of the sides, and it must be the size of the PowerPoint slides.” Here, as you see, it is important to say what you want it to appear in the image. It is also important Specify size and dimensions. We, not to complicate much we have said that you use the size of the PowerPoint slides, so that I looked for and knows the exact dimensions. Although we have not included it, too You can mention a visual style with a description that you can then repeat in the other slides. Or if not, in the same AI chat that you are using asks to use the same style as in the previous slide to take into account. And finally, in the case of Chatgpt You can ask you to offer it in PowerPoint format. This will make the AI pass this slide to the PPTX format, which is the Microsoft tool officer. Copilot and Gemini can give you additional help Copilot is from Microsoft, the same PowerPoint company, and Google has another alternative called Slides, and Gemini’s AI. This means that They will give you extra facilities to create presentations or slides for these own tools. Even if you don’t know what to do, you can start with say you want to create a template or slide PowerPoint in Gemini, for example. Then, AI will guide you for the process and ask you questions to design everything to your liking. Make the slides with gamma Gamma is An application specialized in creating powerpoints using artificial intelligence. Your website is Gamma.appand after registering you will go to a creation screen where you should Choose between three creation options. With a free account you can make a presentation of up to 10 modules, and APRA make up to 60 you will have to go to the payment plan. If you choose the option of Paste textyou can create your presentation from a note, a scheme, or text content that you want to use. First hit the text, and then choose what you want to do. You can generate vignettes or loose ideas from notes or schemes, summarize the extensive text that you have put in several vignettes, or keep the text as it is and distribute it in vignettes. After configuring that, in the section of Paste textyou will go to A second screen to edit instructions. Here you can choose the subject and language, also the tone to be used. You can also choose the amount of text per vignette and many other elements to configure everything to your liking. If you choose the option Triggereverything is simplified to the maximum. First you have to choose the amount of modules, size and language, and then Describe the idea you want. When you have all that click on Generate scheme. Now, you will go to A second step with a scheme of what each of the slides will include. This scheme will be able to edit to your liking. When you have it click on the button Trigger that appears below, and then the slides will be generated. And if you choose the option of Import file or URLthen you will only have to choose a PowerPoint, Word, PDF or slides file, or directly a web page where you point to information, and will be used to create the slides from this material.

The earthquake has revived the fear of a new Fukushima. This time, nuclear power plants are armed to teeth

by

The red tsunami alert issued on the coast of Japan after a strong earthquake in Russia has served as a raw reminder of the 2011 disaster. Japanese televisions cut their usual programming to show an unequivocal order in capital letters: “Tsunami! Evacuate!“The message, shouted in unison by the presenters, resonated with those of 14 years ago. But this time, the nuclear power plants were much better prepared. Context. For millions of Japanese, The scene that was lived this Wednesday It was too familiar. The collective memory immediately returned to March 11, 2011, when an earthquake of magnitude 9 unleashed a tsunami that not only charged about 20,000 lives, but caused the worst nuclear accident of the 21st century in the Fukushima central. Yesterday, the workers of the own Fukushima plant They suspended their tasks and evacuated the nuclear power plant towards higher land, knowing that nuclear safety has suffered a radical transformation. The global nuclear industry not only learned Fukushima’s lessons: it made them concrete, steel and new protocols on an unprecedented scale. The turning point. To understand the magnitude of the changes, we must remember what exactly failed in Fukushima-Daiichi. The disaster It was not caused directly by the earthquakebut for the tsunami that followed. Waves of up to 15 meters far exceeded the containment wall of the plant, flooding the emergency diesel generators and cutting all the plant power of the plant. Without capacity to refrigerate reactors, Three of the nuclei merged. The lesson was brutal: the security margins, designed for probable events, were insufficient before an extreme event. Fukushima was a global attention call that unleashed a regulatory and technical revolution. The paradigm shift is summarized in moving from a probabilist approach (designing for what is expected) to a total resilience (being ready for the unexpected). Not only in Japan. Immediately after the accident, regulators around the world launched A thorough review of its facilities, creating international frames to ensure that the lessons learned will be applied everywhere. China and the United States They promoted strategies so that all nuclear power plants can support an indefinite loss of energy. In Europe, all plants passed Stress tests against earthquakes, floods and total loss of security systems, forcing each country to implement a national action plan in case of finding defects. Gravelines, the largest nuclear power plant in France, reinforced his dike and added new gates Mobile Concrete and steel. Japanese centrals have been working like none, investing billions of dollars. They sealed all possible water input routes with stagnant doors, installed high capacity Achique pumps and built higher walls. Onagawa, the central closest to the 2011 epicenter, survived thanks to its 14 -meter wall. After Fukushima’s accident, the Tohoku Electric Power energy company did not walk with little girls and built A new 2 meter high dikealmost like a 10 -story building. Hamooka raised his breakwater 22 meters above sea leveland relocated the emergency diesel generators in a hill at 25 meters high. Tokai-2 raised A slope 1.7 kilometers longprepared to resist a wave of 17.1 meters. The reactors of the future. These lessons have also moved to the new designs of third and fourth generation reactors, including compact modular reactors (SMR), which incorporate them as standard. The AP1000 and its Chinese CAP-1000 derivative They can keep safe for 72 hours without any human intervention or external energy thanks to passive cooling systems that work by gravity and convection. The European EPR-2 includes double containment, a filtered vent system and A “Core-Catcher” Designed to contain the molten nucleus in the hypothetical case of an accident. And the Nuscale or the BWRX-300 of Gen-Hitachi can be installed as underground reactors, which makes them intrinsically immune to tsunamis and other surface disasters. A safer world. Wednesday’s Tsunami alert is a reminder that we are still at the mercy of nature. But also an opportunity to verify that, in the 14 years that have passed since Fukushima, the defenses of nuclear power plants have become a real fortress. The 2011 disaster was not in vain.

China goes for those who mock their export controls. The focus is in strategic minerals that sustain their power

by

Beijing has just tightened your control over one of its most valuable assets: strategic minerals that feed chips, electrical networks and satellites. A spokesman for the Ministry of Commerce He assured that smuggling will be pursued without concessions. The Asian giant redoubles the pressure. China does not stay in the ads of a firm policy: it has launched an operation that, as they say, already yields concrete results. During the last two months, multiple cases of illegal exports have been investigated, with arrests of involved and a “strong deterrence”, CGTN points out. A key meeting of July 19 at Nanning – with the presence of the Ministry of Commerce, Public Security, Customs, Attorney General’s Office and other agencies – served as an intermediate point after the operation initiated in May. In that meeting it was agreed: Establish a Joint Coordination Center for Export Application and Control of Double Use Articles. Publish exemplary judicial cases and expand the list of foreign entities subject to controls. Issue compliance guides for exporters, with emphasis on avoiding deviations to military purposes. Why these minerals matter so much. Strategic minerals –including rare earths such as neodymium, prseodimio and disposium– They are essential for high -tech industries: computer chips, electric vehicle batteries, wind turbines, satellites and military equipment. China controls about 60% of refined world productionwhich gives you a critical position in the global supply chains. Having this domain allows Beijing to influence key markets and exert economic pressure on international tension contexts. In addition, the refining of these matters requires advanced technology and complex chemical processes, which raises entry barriers to other countries. The threat: smuggling and technological leaks. Beijing’s message is not limited to economic damage. The Ministry of Commerce warned about an added risk: mineral smuggling can facilitate technological filtration towards foreign actors, including those linked to the military. It is feared that certain materials end up in defense applications without going through adequate controls, thus avoiding the official export mechanisms. The authorities claim to have detected sophisticated attempts to overcome the rules: false documentation, transfers through third countries, and fragmentation of cargoes to reduce customs scrutiny. The technical complexity of these schemes forces constant surveillance, according to He Yadong himself. It is not the first time that this is tried to stop. Frenting the smuggling of strategic products is not new, and it is rarely simple. The restrictions imposed by the United States on advanced chips and NVIDIA GPUS offer a clear example: despite the formal prohibition of exporting models such as A100 or H100 to China, China, Recent analysis indicate that these components continue to reach the country through opaque networks and triangulations with third countries. A movement with geopolitical echoes. The decision to harden control over strategic minerals cannot be understood outside the pulse between powers. While the United States multiplies controls on chips, AI and sensitive exports, China counterattacks in one of the few lands where it has a margin of real maneuver: that of critical raw materials. The country is responsible for more than 85% of the global refining of rare earthsand has begun to use that position as a pressure tool. He already demonstrated it in 2023 with the imposition of licenses To export Galio and Germaniotwo essential minerals for advanced electronics and defense. This new turn hardens its position and is interpreted as a response to the western fence. It is not a total closure, but a reminder that who controls the materials, controls a part of the game. Will these measures work? What is not clear is whether these measures will be effective in the long term. Smuggling networks usually adapt rapidly, especially when there are global interests at stake and high economic benefits. Nor do we know if these decisions will affect prices, the international supply or the negotiating position of China in future technological disputes.

Save the price or save power. And he has chosen the path of self -destruction

In just ten minutes of video call, eight OPEC+ countries made a decision with the potential to alter the balance of the global energy market. Behind this new movement, that could be expectedthere is something else: a carefully calibrated strategy, with economic and geopolitical implications that could spread far beyond the barrel. Opening the tap. Saudi Arabia, Russia, Iraq, United Arab Emirates, Kuwait, Kazakhstan, Algeria and Oman – the eight OPEC+ countries that They applied volunteer cuts In 2023— they have been gradually increasing Your production. Now they have decided to accelerate this process: from August they will add 548,000 additional daily barrels, and do not rule out another similar increase in September. According to the official notethis could be completed before planning the total reversal of 2.2 million barrels per day that stopped pumping last year. Do you enjoy good health? It seems that yes, or at least that the reason declared by the OPEC+. From the organization They have expressed that there is a “good health of the oil market”, with low inventories and a global demand that remains stable. Giovanni Staunovo, UBS analyst cited by BloombergHe explained that “the market remains adjusted, suggesting that it can absorb additional barrels.” However, there are more reasons behind the scenes. According to Goldman Sachs bank has pointed out for Reuters that the measure is part of a broader strategy to normalize idle capacity and discipline the schist sector in the US. In this way, the entity provides that the eight countries will increase its collective production by 1.67 million BPD between March and September, with Saudi Arabia leading more than 60% of the increase. The threat of oversupply. In the short term, the market seems receptive. The same day of the ad, the price of crude rose slightly, challenging the most pessimistic predictions about the fall in demand. However, medium -term consequences are uncertain. The reality is that the market is currently “adjusted”, commercial tensions and The “Peak Oil” Chinese They could translate into a significant oversupply for the end of the year, especially in winter. The International Energy Agency It foresees a surplus of up to 1.5% of world consumption for the fourth quarter of 2025. In addition, some experts like Doug King, from RCMA Capital, They have remembered in Bloomberg that the “official” increase of the offer does not always equals real availability, since countries like Kazakhstan They keep breaking installments while Saudi Arabia presses for compensation to those who have overcome in the past. A possible domino effect. The OPEC+ decision impacts unevenly. For importing countries such as India or the European Union, the lowest prices of oil relieve internal economic tensions. But for producers outside the poster, the stage is more uncertain. The pressure on the American shale sector, highly dependent on prices above $ 60-65 per barrel, intensifies. Here enters the United States. Interestingly, this measure is also aligned with the political interests of Donald Trump, who has promised to reduce fuel costs to relieve the crisis of the cost of living. Your pressure on OPEC to increase production is well known, and its insistence on Apply tariffs and interest rate cuts could be tilting the balance in its favor. But there is another face: the American oil industry, one of Trump’s main economic and political bastions, It is also the most exposed. If prices fall below 60 dollars, many shale companies could see their profitability compromised. As Oilprice has pointed outdespite the current difficulties of companies such as Exxon and Shell, demand remains more robust than expected, challenging the collapse narrative for electric vehicles. However, the risk is clear: a new price drop could put in check to the United States’s own energy, which has already announced less perforations for this year due to the uncertainty of the market. Can Riad hold it? This is one of the big questions. Despite its apparent confidence, Saudi Arabia also faces internal pressures. According to the International Monetary Fundyou need prices above $ 90 per barrel to cover your budget. The economic reforms of the heir prince Mohammed Bin Salman, which include ambitious national projectsThey require sustained investments. According to Bloombergif prices collapse, Riad could be forced to cut public spending or even withdraw oil from the market to defend their income. A cyclical dynamic. This episode reveals a change in the OPEC+strategy: less emphasis on high prices and more focus on recovering market share, even at the expense of lower prices. As Oilprice has detailedoil remains a market subject to temporary swings, and large oil companies are better prepared to resist. But volatility remains the sign of time. The next chapter will be written on August 3, when the OPEC+ decides if it continues with the last stage of the planned increase, the oil market faces a key question: will the OPEC+ short -term pricing stability work in long -term influence?

Spain promised them very happy as the power of the data centers. Did not have the heat waves

by

On July 19, 2002, at 06:33 PST, Google and Oracle Data Centers in London They stopped working. The reason was not a human or electrical failure. The only thing that happened is that 40 ° C were exceeded in the British capital, and the cooling systems of that data center could not support those temperatures. The result: falls of multiple services for hours. It was a dangerous advance (and we are talking about London, which is not especially hot) for data centers, especially considering what comes to us. Climate change also threatens data centers. The only good news of this summer’s extreme heat is that It will be carried compared to the one in the coming years. The theme, which is worrisome to humans, has a surprise derivative: these extreme temperatures are going to be a colossal challenge for data centers. We do not stop seeing record temperatures one summer after another, and that will test the cooling systems of those centers. Hello, cooling. There are no definitive data on the temperature at which data centers must work, and while certain experts They recommend that work in a range of 18 to 27 ºC, others They hold that the range must be even cooler, between 17 and 21 ºC. And of course, that is only achieved with powerful air and liquid cooling systems. Heat comes out. If it is more hot, it is necessary to refrigerate more, and that imposes greater electrical consumption and therefore, a greater electricity bill. Of not controlling those temperatures the efficiency of the components is decreasing. As in mobile. It is exactly the same thing that happens in our mobiles and computers when they overheat: if the cooling systems fail to bother those temperatures, The ‘throttling’ is normally produced: The components “go round” to consume less and dissipate less heat. And the water, too. In many data centers liquid cooling also plays a fundamental role, and in the face of heat waves, water consumption also rises. That is especially worrying now that Big Tech have announced that they will invest tens of billions of dollars in new data centers for AI. Liquid cooling to power. In those facilities dedicated to AI a huge amount of chips accumulates in small spaces, which makes liquid cooling solutions much more appropriate. And the same thing happens again: before extreme temperatures, it is up to “climb the cooling systems to deal with possible overheating. Evaporative cooling. Of course, engineers who develop these types of projects go to solutions to try to avoid problems, especially when data centers are in areas where summers are especially extreme. There come techniques coom the Direct evaporative coolingin which the refrigerated and humidified air is directly entered the data center. There are other techniques such as water cooling towers and of course an intelligent management of air flow management is optimal. Be careful where you look up your data center. That makes it more and more important to choose the ideal location for new data centers. In Spain Aragon is becoming In an absolutely protagonist region. There are several projects in which Big Tech will put (theoretically) in progress data centers in this autonomous community, although the risk of extreme temperatures there is not so high as would be further south of the peninsula. But with increasingly high temperatures in summer, what can be done? Ice cream clusters. The option in some cases is simply to choose locations in which the weather is much cooler … or even icy. Facebook has already built several Data centers in Lulea (Sweden) In 2013, but in Spain we have an even more striking case: the Social Security CPD He moved from Madrid to Soria for the simple reason that it is colder there. That, among other things, allowed to save The 150,000 euros that would have cost the cooling of these systems in Madrid during the summer.

While the spotlights point to b-2 bombersthere are other deployed planes that go through practically unnoticed: KC-135 Stratotankerveterans with more than six decades of service that have once again operated in the Middle East, just when the United States has attacked several nuclear facilities in Iranian territoryincluded Fordow, After reinforcing its military presence in the region in full climb with Israel. They do not launch missiles or participate in direct attacks, but their role is essential: they allow fighters, bombers and recognition planes to hold prolonged flights without landing. In the military deployment that the United States is executing in the Middle East, the KC-135 Stratotanker It is not a footnote. It is part of the logistics nucleus that allows aerial machinery to continue working without interruptions. According to Media as Reuters and BBCat least 30 cistern aircraft have been mobilized, mostly of this model, to accompany f-16 fighters, F-22, F-35 and other aerial assets deployed in the region. Its function may seem secondary to the naked eye, but has direct strategic implications: to the replenish in flightthe KC-135 eliminates the need for aircraft to interrupt their mission to refuel on land. That translates into operational continuity, greater tactical autonomy. And it’s not just a support for fighters. It also serves as a support for bombers, recognition aircraft, medical units and, when necessary, allied forces A beast with more than 60 years of history (and still has rope) When the KC-135 It flew for the first time in 1956the world was another. The Cold war He dominated the military strategy, and the United States needed a fleet capable of sustaining its aerial power at a global scale. Boeing offered a solution: a military variant of the Model 367-80the prototype that would also lead to the mythical 707. Thus was born the Stratotanker, which began to reach the air bases in 1957 and that, against all prognosis, remains in service in full 2025. Of the more than 700 built copies, much was subjected to a process of radical modernization. The most visible change: engines. The ancients were replaced by CFM56more efficient, powerful and silent turbo. Thanks to them, the KC-135R-the most common version today— consume 25 % lessit costs 25 % less operating and is almost 96 % quieter than the original model, according to official US Air Force data. But not everything has been mechanical. Throughout the decades, the KC-135 has also been adapted for very different tasks: aerial command, surveillance, experimental tests or even missions in compliance with the open skies treaty. Few platforms have demonstrated so much versatility and resistance to the passage of time. How the Replacement in Flight works From outside it may seem a simple maneuver: two planes flying nearby, one transfers fuel and everything continues as if nothing. But in reality, aerial refueling is an extremely delicate operation that requires Perfect coordination between pilots and operator. In KC-135, this task falls on the call Boom Operatora crew member that is located at the back of the plane, lying down, with direct vision of the receiver and total control over the extensible pole of refueling. That articulated arm (Flying Boom) It is the main tool of KC-135 to transfer fuel in flight. Its design allows a precise connection between aircraft that fly at high speed and altitude. The connection requires absolute concentration: the operator guides contact and keeps it stable even in turbulence or maneuvering conditions. In addition to the pole system, some KC-135 are equipped with an additional system: the Druga kind of aerodynamic funnel that allows us to refuel aircraft with probes, as European helicopters or fighters. There are also models with pods in the wings that allow supplying two planes at the same time. All this makes Stratotanker a flexible platform, capable of adapting to multiple configurations according to the mission. A key piece also in the modern war Behind his austere silhouette and his gray paint without ornaments, the KC-135 hides an optimized machine for efficiency. It is propelled by four large thrust engines, capable of taking it at speeds close to 850 km/Hy to operate at altitudes up to 15,240 meters. He is not intended for agility or combat, but meets an immovable premise: being there when he is needed. Can take off with a maximum weight of 146 tons and transport more than 90 tons of fuel to transfer to other aircraft. If the mission requires it, it can also load up to 37 passengers or about 38,000 kilos of material on the upper cover, just above the refueling system. All this in a structure of 41.5 meters long, with a wingspan close to 40 meters. As for its reach, it can cover more than 2,400 km with 68 tons of transferable fuel on board. In type missions Ferrywithout external load, can exceed 17,700 km, allowing intercontinental flights without scales. In medical evacuation missions, the KC-135 becomes a kind of flying ICU. Thanks to special pallets, you can transport patients on a stretcher with a specific medical crew. It is this versatility is what Stratotanker has made a piece difficult to replace. The KC-135 continues active duty more than SEis decades later of his first flight. Although the KC-46 pegasus It has already begun to assume part of its functions, Stratotanker is still one of the main resupply platforms of the US Air Force. Its maintenance, its successive modernizations and its capacity proven in multiple scenarios explain its constant presence in long -range operations. Images | US Air Force (1, 2, 3, 4) | Master Sgt.

China has built the most elegant economic power lever in modern history: rare earths

by

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.
