forget

The Silver Route seemed like the perfect train for the Spanish west. They seek to recover it with one objective: forget about Madrid

by

Cáceres and Salamanca are separated by just 200 kilometers but the journey takes seven hours in the best of cases and requires passing through Madrid. We talked, of course, about going by train. And the capitals of these two provinces represent one of the biggest railway holes that our country has. The situation is not unique in Spain (from Murcia to Granada you also have to go through Madrid) but perhaps it is more bloody because one day there was that option that structured the west of Spain. It was known as the Silver Route. Now, more than 40 years after its closure, there are those who continue fighting for its reopening. A line that was born sentenced From Seville to Gijón, passing through Mérida, Cáceres, Salamanca, León or Oviedo. The Silver Route It was designed as a railway corridor for passengers and goods away from the large Spanish economic centers. It was about finding an alternative so that not everything went through Madrid, Bilbao or Barcelona. And, curiously, its origin must be sought very far from these cities. It was in Paris in 1877 when the contract was signed to build a railway between Palazuelo (current Monfragüe station) and Astorga, they explain in The Extremadura Newspaper. The project was ambitious as it passed through a lot of unpopulated area in its attempt to connect the north of Extremadura with Salamanca, Zamora and León. Yet, the line went ahead in the last years of the 19th century. Between 1893 and 1896, the four sections that would end up forming the most representative axis of the line were inaugurated from south to north. This was the backbone of a road that connected to the south with the Mérida-Seville section and the Venta de Baños-Gijón in the north. Without a large city to drive it and without direct access to a large port, the line was falling into ostracism. First, because the State did not find sufficient reasons to modernize it and, at least, electrify it. And without investments, the tortuous path became less attractive for passengers and companies. The axis survived the Civil War but beforehand an investment had been requested that never arrived. In 1933, the iron bridges were replaced by steel ones but no major efforts were made. In the following years, they point out in the local mediaderailments and accidents multiplied due to lack of investment. For decades, once sentenced, the line remained open but in 1984 its definitive closure was confirmed. By then, the trains were barely running at 50 km/h, an average speed lower than that recorded during their opening. A train bus accident in 1981 in which a woman died put the finishing touches on a decision that began decades ago when no one wanted to invest in the western axis. Let it come back! Today, the connection between Cáceres and Seville, passing through Mérida, continues to exist, although it is a single-lane railway and is not electrified. The connection between Salamanca and Gijón is also maintained. But how you can see on this Adif mapa hole separates Cáceres and Salamanca. From Plasencia, you will see a green line leaving towards the north. In Salamanca, another leaves in a southerly direction. Are they projects to recover this train? No, they are Greenwaysconditioning of the old railway section to convert them into easy paths for walking, running or cycling. What some institutions have been demanding for years is that these Greenways are not the only vestige that remains from those days. In 2023, the city councils of Salamanca, Cáceres, Béjar, Plasencia Guijuelo and Hervás together with the Chambers of Commerce of those first three cities signed an institutional declaration demanding the return of the train. “Employment, creation of opportunities, logistical development, diversification of the productive system and stopping depopulation,” with these words they began a text to justify their demands. It pointed out some technical issues such as that the section between Plasencia and Salamanca has 4G network coverage on 90% of the route. But, above all, it was remembered that the new train could be an alternative route for the transport of goods in the western area, capable of connecting the Atlantic ports in the north with those in the south without passing through Madrid. This was the premise, in fact, with which the idea of ​​resurrecting the West Corridorunder the Government of José Luis Rodríguez Zapatero. A project that, as they remember in the text, was not carried out. in the diary Today They collected information that the Gijón Chamber of Commerce put on the table in 2022 to defend this line: it could capture up to 625,000 journeys for goods which now carry trucks going up the A-66, also known as Vía de la Plata. Beyond unfulfilled promises (in addition to Zapatero, José María Aznar also promised to reopen the line after Felipe González closed it to passengers in 1984 and to goods well into the 90s), one of the biggest problems that this Western Corridor has is that it does not fall within the plans of the European Union as far as the railway is concerned. The Trans-European Transport Network ignores this and maintains that hole already mentioned between Cáceres and Salamanca and Salamanca and the south of Asturias if it is not passing through Valladolid. Regardless of whether we are talking about a passenger or freight network, the result is the same. That is why from the Corredor Oeste platform, together with the city councils and the rest of the local organizations, They have been organizing mobilizations and meetings to press and get the project taken to Europe. According to his calculations, it would hardly be necessary to invest 1.9 billion eurosvery far from what is being invested in other corridors such as the Mediterranean, which already exceed 8,000 million in investment. They also defend that the new Silver Route railway would be key to connecting the Atlantic Corridor, which does have European approval, with the Spanish south, offering a … Read more

charges in four minutes and 6,000 hours of stability to forget about lithium

by

I think we all dream of that moment: connecting our cell phone to the power and having it go from 0 to 100% in the time it takes to make a coffee, without the battery suffering any long-term damage or losing capacity over the months. This still sounds like science fiction, but it is what a team of researchers in China has just proposed and they have achieved it. In short. A consortium of scientists from Southeast University, HiNa Battery Technology and Yangzhou University has developed a new quasi-solid electrolyte (QSE) designed specifically for sodium metal batteries. The results of your research, published in the scientific journal Nano-Micro Lettersshow how they have achieved ultra-fast charging (equivalent to filling the battery in about four minutes, at a rate of 15C) while retaining 90% of its capacity after 2,000 high-speed charge and discharge cycles (3C). Sodium has just hit the table compared to lithium. More in depth. To understand the magnitude of this finding, you have to look at the current market. sodium batteries They have been capturing the attention of the industry for some time because sodium is a material infinitely cheaper and more abundant on Earth than lithium, which makes it possible to avoid global supply chain bottlenecks and price volatility. Until now, however, sodium’s big Achilles’ heel was the “equivalent trade-off”: if you wanted fast charging, you drastically sacrificed battery life and safety. This was due to the slow transport of sodium ions and the instability of the interfaces within the stack. This new advance makes a symmetrical sodium cell operate stably for 6,000 hours uninterrupted without failures related to short circuits. For the end user, this translates into a near future where electric vehicles and electronic devices will be much more affordable, safer and have charging times that will completely eliminate the famous “range anxiety.” The science behind the milestone. Researchers have dubbed this solution “dual intertwined mediator engineering.” In simple terms, they have completely redesigned the highway on which the ions travel inside the battery, eliminating traffic jams and reinforcing shoulders, without losing the physical-chemical rigor of the process. In conventional electrolytes, sodium moves clumsily, achieving a transfer number (the metric that defines how efficiently and freely ions move) of just between 0.4 and 0.7. The new electrolyte, called Sn-FB QSE, achieves an almost perfect index of 0.94. This indicates “single-ion conduction”: sodium travels individually and directly, without dragging heavy elements in its path. To achieve this, they have used two main chemical protagonists that act as a team: The releaser (DFOB⁻ Salt): At the molecular level, this salt weakens the strong coordination interaction between the sodium ions and the polymer network of the electrolyte. By removing this chemical “glue”, the sodium is freed. Molecular dynamics simulations show that ion diffusion reaches 16.8 Ų ns⁻¹, about six times faster than in traditional liquid electrolytes. The builder shield (Tin ions, Sn²⁺): During charging, the Sn²⁺ is first reduced at the anode. This creates a protective film (scientifically known as Solid-Electrolyte Interface or SEI) rich in a sodium-tin alloy. This layer acts as a mold that homogenizes the electric field, forcing the sodium to deposit flat and uniformly. Goodbye to the dreaded “dendrites”, those needle-shaped metal structures that pierce the battery and cause short circuits. Additionally, the dual effect is completed at the other end of the stack. While tin protects the anode, DFOB⁻ is sacrificially oxidized at the cathode to form another extremely robust, inorganic protective layer (CEI) just 14 nm thick. This thin film stops the degradation of the electrolyte in its tracks at high voltages, guaranteeing the longevity of the battery. From the laboratory to the real world. Often, these discoveries remain in tiny laboratory “button batteries” that never see the light of day. But the most promising thing about this research is its scalability and practical application. The researchers constructed flexible, pressure-free “pouch cells.” In a video demonstration, they managed to use one of these batteries to charge a smartphone continuously, even while repeatedly bending and manipulating it with their hands, demonstrating exceptional flexibility and resilience. Added to this is that the electrolyte remains stable up to 4.7 volts, opening the door to pairing it with even more powerful materials in the future. And most importantly for the industry: this approach is fully compatible with current manufacturing methods and could even be extended to lithium and potassium metal batteries. The future knocks at the door. Charging your phone in four minutes without destroying the battery in a few months has always been the Holy Grail of consumer electronics. With materials engineering innovations such as this quasi-solid electrolyte, sodium is no longer “the cheap brother” to position itself as a very high-performance technology. Although there is still a way to go to see these batteries on commercial shelves, this discovery makes it clear that the future of portable energy involves abandoning exclusive dependence on lithium. The era of accidentally plugging in your cell phone and having battery power for the entire day is a big step closer to being our daily routine.

“We recognize that we have done things wrong.” Peugeot apologizes for the PureTech and presents the engine that wants to make us forget it

by

Peugeot has decided to close one of the most uncomfortable chapters in its recent history. The lion brand gathered the motoring press in Madrid a few days ago to do two things at the same time: apologize for PureTech engine problems and introduce your substitutethe new Turbo 100, a block designed from scratch that is in fact already available. Bad reputation. For years, the PureTech 1.0 and 1.2 gasoline engines that the Stellantis Group installed in brands such as Peugeot, Citroën and Opel have had a considerable bad reputation for two of their most common breakdowns: their oil dipped strap deterioration and excessive oil consumption. Now Peugeot has come forward and publicly acknowledged that it was wrong. “We recognize that we have done things wrong,” admitted those responsible at the press event, according to collect I amMotor. And, above all, that They took too long to respond to clients and workshops. Figures. In Spain alone, around 500,000 units of these engines were sold, adding the three affected brands, and more than five million were manufactured throughout Europe. Furthermore, Spain is more affected than other territories by how things go for Peugeot, since as they mention Our colleagues at Motorpasión, Stellantis produces up to 14 models here in its plants in Vigo, Figueruelas and Villaverde. The brand closed 2025 with more than 81,000 cars sold in our country, so regaining trust is a priority for the company. Issues. On the one hand, the timing belt deteriorated due to chemical aggression, because on short, daily city trips (3 to 5 kilometers), the fuel mixed with the oil, swelled the belt and ended up releasing fragments that clogged the oil pump, which led to quite serious breakdowns. On the other hand, in the first generation PureTech (2014 to mid-2018) the repeated cycles of cold and heat accumulated carbon in the piston rings, which increased oil consumption. As the Stellantis engineers explained, the determining factor was not the total kilometers of the car, but the “quality” of those kilometers. Between the lines. Peugeot insists that this was not cost cutting. Its engineers denied that controls were eliminated to save and they remembered that “non-quality in the end is very expensive”, alluding to what extended guarantees now cost. The real failure, according to the brand, was in testing protocols that did not take into account the intensive urban use that a good part of the drivers in Spain, Portugal, France or Italy do. The wet belt, by the way, was chosen around 2010 because it was then a technically sensible solution, being quieter and with less friction than a chain, and useful for balancing the internal pressures of a three-cylinder engine. A decision that other manufacturers madeincluding Japanese (like Honda, although in a much more conservative way, until it turned out that it was not a good idea). The new engine. Here enters the Turbo 100presented by Fabien Gouzonnat, Director of Engine Development in Europe at Stellantis, and Vincent Jaquier, Engine Project Manager at Peugeot. At first glance it looks similar to the PureTech, because it had to fit in the same cars, but inside it is something else. In fact, the brand states that 70% of all the components that make up the engine are completely new and of the above the only thing they say is preserved is screws and some gaskets. The most notable change is that it dispenses with the belt and adopts a silent and maintenance-free distribution chain throughout the life of the car. And not just the chain. The Turbo 100 is a 1.2 three-cylinder engine with 100 HP and 205 Nm that debuts technology that has hitherto been unusual in high-volume gasoline. It works with a Miller cycle, direct injection at 350 bars and a variable geometry turbo (the first that Peugeot uses in a mass-produced gasoline engine). To reduce oil consumption, the pistons have been completely redesigned, with an internal cooling gallery and reinforced segments, as well as a new oil separator with a more resistant membrane. The brand assures have reduced mechanical wear up to 80%. To validate it, he says that he has subjected the block to more than 30,000 hours of bench tests and more than three million kilometers in real conditions. The guarantees. The other front is customer trust. New cars with the Turbo 100 extend the usual coverage up to 8 years or 160,000 km through the Peugeot Care program, as long as maintenance is carried out on the official network. For those who already have a PureTech, there are a web tool that reimburses for repairs paid between January 1, 2022 and December 31, 2024, providing the invoice for the repair and the three previous maintenances. And if the engine has not failed, the Check Plus certificate (free) covers up to 10 years or 180,000 km, even for second-hand cars or those with maintenance carried out in independent workshops, as long as they can be accredited. And now what. The Turbo 100 is already available in the Peugeot 208 and 2008, and serves as the basis for the 110 and 145 HP hybrid versions that are fitted to the 308, 408, 3008 and 5008, in addition to being extended to the rest of the group’s brands. It’s clear that Stellantis is making a monumental effort to eliminate the footprint left by its PureTech engine. Time will tell us if this new engine lives up to its promise.

We believed that the secret to rest was sleeping eight hours. A study has shown that we forget a big element

by

One of the mantras most repeated ad nauseum in the field of health is related to the need to sleep at least eight hours nightly. A goal that has been widely studied with the repercussions that failure to meet it may have. But now we have seen how the regularity in sleep is a much more powerful preacher of long-term health than mere duration. It’s when you sleep. Although we had very ‘glorified’ how much sleep we have to, trying to make up for lost hours on the weekendthe reality is that the important thing is to have good consistency, as is the case with many other processes. The regularity. The scientific consensus on this paradigm shift is gaining strength, and the last major proof is published by the National Sleep Foundation with an article that points to this regularity as one of the most forgotten components of our nocturnal habits. The key here lies in the internal clock, since we must remember that the time of waking up and early exposure to natural light is what activates our internal system with the cortisol release. In this way, by maintaining a constant reference, we ensure that critical biological processes, from hormonal secretion to body temperature, are regularized. When we don’t respect it. Just like when we travel to another country and we follow schedules very different from ours, the same thing happens here. We have the classic situation on the weekend, where we go to bed late and get up two or three hours later than usual, and surely the feeling when we get up is exhaustion. This is what is now known as ‘social jet lag’ or ‘Monday jet lag’, responsible for that mental fog, lack of alertness and low cognitive function with which we start the week. A shield. Unlike total sleep duration, regularity is a direct marker of the integrity of our circadian system, since when the internal clock and the demands of the environment become out of sync, known as chronodisruption, the body suffers. Just like when we travel between countries or experience time change. Here, a study published in Health Data Science HE dedicated analyzed more than 88,000 adults in the United Kingdom and found that irregular sleep patterns are associated with a greater predisposition to suffer from up to 172 different diseases. In fact, actigraphy studies have shown that intra-individual variability in our sleep hours is a direct marker of all-cause mortality, so trying to accumulate hours on Saturdays and Sundays not only does not save the furniture, but it puts us at risk. The impact of irregularity. In this sense, a linear relationship can be seen between sleep instability and the risk of suffering a cardiac event. But trying to “compensate” for tiredness on the weekend also results in worse insulin sensitivity and ends up altering glucose metabolism, which causes the bill to be quite expensive in the long run. Furthermore, the lack of a clear sleep routine causes a chronic pro-inflammatory state. This alteration compromises our immune response to pathogens, worsens the regulation of autoimmune diseases, and decreases the ability of our cells to repair themselves and eliminate metabolic waste. In summary, following set hours of sleep is essential if we really want to have optimal results in our daily lives.

how to create an interactive list so you don’t forget the things to pack

by

Let’s explain to you how to create an interactive packing list with everything you have to carry in your suitcase. We are going to do this with Claudea artificial intelligence which will create a module with elements that you can select when you put them. This list will have a counter in addition to the checks, so always you will know what you have put in and what you still have to put in in your suitcase, and this way you will make sure that you don’t forget anything. There are several ways to proceed, letting Claude create the list automatically for you based on where you are going to go and other information, or by dictating the items you want to have. Automatic packing list First, you can have Claude create the packing list for you automatically. For that, you’re going to have to tell him where you are going, for how many days and the activities What are you going to want to do? You can use a prompt like this: “I want you to make me an interactive packing list. I am going to spend 5 days on the Costa Brava during Easter from April 3 to 6. There will be some hiking, trips to the beach if the weather is good and some dinner at a restaurant. Can you make me a complete suitcase list, including clothes, shoes, toiletries and various items?” The most important thing is indicate that you want it to be an interactive list. When you ask him, Claude will first look for the weather information that there will be during those days, with the temperatures that you will encounter. And based on this data and everything you have said, it will generate your packing list. As you can see, the list will indicate what each thing is for, and there will be counters with which you will know how many items on the list you have added and how much remains to be added. Besides, you can ask it to remove a group of elementssuch as removing the hiking ones because you’ve changed your mind and don’t want to go to the mountains, and Claude will redo the list to your liking. Personalized packing list item by item But if you don’t want Claude to add a bunch of stuff that you might not need, then it’s best to create your personalized packing list with the elements you have in your head. To do this, you will have to ask him for a list telling him the items you want. You can use the following prompt: “I want you to create an interactive packing list for my trip to Dublin from April 23 to 26. It should only have the items that I tell you. I want you to add: Mountain shoes, 4 long-sleeved t-shirts, 2 sweaters, 1 jacket, 2 jeans, 4 underwear and 4 pairs of socks, 1 pajamas, toiletry bag, charger for cell phone and watch, passport, ID, sunglasses.” As you can see, in the prompt we have started by telling you that we want the interactive packing list, and then We have given you the list of items we want to add. Claude himself is in charge of categorizing them. We have also specified the dates and the place we are going, then we will tell you why. When you have the list added, leave that chat and don’t touch anything else. Then, if something else occurs to you, you can go back to the chat and ask him to add or remove thingsand Claude will regenerate this list. A useful trick is that you can ask Claude if you are missing something important on your list. That is why we told him at the beginning where and when we are going, because when you ask him if you are missing something, he will be able to take this information into account and tell you the things that you may be missing. In my case, a trip to Dublin reminded me that I will need a plug adapter, and I took the opportunity to add it.

There’s a reason you forget to write things down on your shopping list: prospective memory.

by

Have I turned off the gas? Where have I left the keys? What was I coming to the kitchen to do? These are some of the questions we often ask ourselves. Of the three, the last one is perhaps the most interesting, the one that involves a form of memory with which we are not very familiar: the prospective memory. What exactly is prospective memory? This form of memory is what refers to our ability to remember planned or future actions, to remember intentions. It could be remembering what we were going to look for in the refrigerator or the dentist’s appointment on Thursday. Prospective memory is something we deal with in our daily lives, but it is not a concept that many people are familiar with. Neither do the experts: research on this form of memory was, until the beginning of this century, virtually nonexistent. But in recent years we have managed find out some key aspects of this memory. For example, we now have an idea of ​​which brain regions work for the correct functioning of future memory. A 2010 study found three regions of the brain whose activity was linked to prospective memory results: the parahippocampal gyrus, the left inferior parietal lobe, and the left anterior cingulate. However, there is still much to investigate in this regard. Other studies, for example, have given greater importance to the activation of the right lobe in relation to this memory. Othersfor example, emphasize the role of the anterior prefrontal cortex and the medial temporal lobe. But it’s not all neurobiology. Things we forget Why do we forget what it is that we were going to write down on the shopping list? Prospective memory is not very different in this from other forms of memory. Here attention is key. In one interview for RAC1 radiothe neuropsychologist Saul Martínez-Horta explained, starting from “what did I come to the kitchen to do”, he explains how it is that we have this facility to forget things. Distractions are one of the main factors that affect this memory. If we go to the kitchen to get salt, but in the meantime we remember that we left the oven on, this second fact will make us confused and make it more likely that we will forget about the salt. In Martínez-Horta’s own words “Normally what makes us forget what we should do is the saturation of the system and the distraction mediated by another event. brain capacity “It is limited and sensitive to distraction, so it is relatively easy for us to direct our attention to something other than what we are doing.” Concentration is, therefore, key if we want our prospective memory (or our memory in general) to have more of itself. Memory can be trained, but generally the exercises that allow us to do it They are not useful beyond of the memory function they seek to train. That is to say, there is no evidence that solving crossword puzzles will make us remember to buy popcorn for when we have visitors. That does not mean that we are helpless. Some healthy habits impact in our brain’s ability to perform its tasks, and although studies focused on prospective memory are scarce, it may be a good idea to incorporate them. A varied diet, exercise and sleep properly they can help us with our memory. Perhaps, they can also help us remember what it is that we were looking for in the closet before receiving WhatsApp from our brother-in-law. In Xataka | How much information can our brain store?

The bird to Andalusia has stopped again. This time he has touched Malaga in an July to forget at high speed

by

The president of Renfe, Álvaro Fernández Heredia said, just a few days ago that Renfe “tried not to leave anyone behind.” Only a few months ago, Oscar Puente, Minister of Transportation, took a breast out of the company’s punctuality. Yesterday, the high speed line in Malaga suffered delays again. It is the last case in a summer that seems to accumulate problems. The latest. The detachment of a vault and water leaks. That is the reason why the bird was delayed yesterday on its way to Malaga. They point out in The worldthat the problem was in an aquifer that borders the tunnel and that caused the filtering of water. Quickly, Adif went out to make clear that the structure of the tunnel and official sources were not compromised indicated to local media as South newspaper that no cut in the line had occurred or the passengers had to be evacuated. Everything was solved taking the trains to the farthest path of the affected wall. “Minimum affectation”. With these words, according to COPERenfe defined the impact that this last incidence has had. The company assured that the delay did not exceed half an hour and that it was because the trains had to circulate at low speed and in a unique way. For the Popular Party it is a “negligent action” that should force Pedro Sánchez, president of the Government, to face. Beyond political proclamations, the truth is that the Malaga case is the last one of a summer in which Adif and Renfe are focusing the debate on the reliability of their service. Click on the image to go to the original tweet The eyes set in Adif. The involvement in the high speed line was taken yesterday by Renfe but also ouigo and Iro. It has been in Adif in whom they have put their eyes since they are responsible for the maintenance of the roads. In fact, in Malaga today They remember that that of the aquifer is a problem that has been maintained since 2005 when the works “pricked” the same and since then Adif pays compensation to the neighbors for the damages caused. José Ramón Carmona, general secretary of the PP of Malaga, pointed out that the problem is the “investment abandonment and the absence of maintenance in the rail network that entails a serious infrastructure degradation.” The situation is delicate because the leaks of these aquifers directly affect the Abdalajís Valley, where the tunnel was built. They explain in eldiario.es That the tunnel was built with a stagnant lining, formed by a reinforced concrete ring inside by prefabricated dovelas. It has a thickness of 35 centimeters and concrete of different resistance was used in two different sections to avoid leaks while releasing the pressure that water can cause. A summer to forget. Adif claims begin to be constant in a summer that is being to forget. The most controversial case focused the looks the first days of July when A train was stopped 13 hours On the tracks, without assistance and with an old woman who ended at the hospital. So, The Government and Adif They pointed out that the problem was originated by an ouigo train whose fault resulted in a domino effect that ended with the Renfe train abandoned to its fate. In Ouigo they pointed that nothing would have happened if Adif had maintained the facilities correctly. And Adif defended himself by ensuring that they would put an ongoing plan to solve the possible problems in their catenaries. Days later, A train stopped In Toledo for a problem in the infrastructure, which once again stopped travel between Madrid and Andalusia. Beyond Adif. To problems directly linked to Adif, other incidents that have stopped circulation in recent months or weeks must be added. We have had delays and cancellations for uncontrollable phenomena such as torrential rains either Fire next to the tracks But also for him copper theft which came to derive in the collapse of the Andalusian bird and in the accusation of Boicot by Óscar Puente, Minister of Transportation. Balls out. In spite of everything, the leaders of Renfe and the bridge itself have long since defended that the train situation is not as bad as we imagine (or we see). RENFE President himself He presumed days agopointing out that the company is among the best in Europe and criticized those who defined the last days as “rail chaos”. In December 2024, Bridge defended exactly the same in a session in the Congress of Deputies. The truth is that passengers do not seem to see it like this and have negatively highlighted Renfe’s performance in recent months. Renfe also has expanded the times To return the money in case of delay. And in The confidential They collected how delays in high Spanish speed have shot themselves in recent years.

Before many we wanted a Xiaomi Su7. Now we also want the new Xiaomi Yu7: The company sold 200,000 units in three minutes In China and beat The remarkable record of his first model. But attentive, because that overwhelming success can now end up replicating in the rest of the world. It has already happened with its mobiles, and in Xiaomi they seem prepared to replicate the same strategy with which they reaped success in that market. In 2027, expansion.Lei Jun, CEO of Xiaomi, indicated on Wednesday that he hopes to start selling his electric vehicles outside China. For now it is confirmed with its market, where you are getting kneel. In its first year selling Xiaomi electric cars has lost 800 million dollars, but it is that That is excellent news for your future. Traditional manufacturers tremble. Xiaomi’s international expansion is a great news for them, but potentially terrible for European manufacturers. The reason is that Xiaomi electric vehicles compete in benefits with the best of European manufacturers, but do so with a much lower price. We have a clear example in Porsche, who has fallen 30% in sales in the last yearespecially for the irruption of Xiaomi Su7. Of choltoteléfonos to chollocoches. Xiaomi’s strategy is traced to which he already allowed him to destroy competition in the mobile industry. His smartphones, especially at the beginning, were choltoteléphones that They offered high-end specifications at entry-media range prices. The same is expected to occur when exporting their cars, which have high -end cars benefits of European manufacturers, but which cost significantly less. It is a battle that traditional mobile manufacturers – those of Apple, Samsung or LG of the time – have already dealt with and, mostly, lost. The example of Yu7. The latest creation of Xiaomi, the Yu7, follows the trail of its predecessor: autonomy of about 540 km, battery that carries 80% in 12 minutes – the Tesla Model and or the Porsche Macan takes more than 20) and acceleration from 0 to 100 in 3.3 seconds (in the Xiaomi Yu7 Max, the most powerful) and power of up to 681 hp (630 hp in the macan, 514 CV in Model Y). Volkswagen already knows what can happen. Volkswagen had a well -off position in China, leading the distance sales of its rivals. However, in recent months these sales have collapsed, although in that case it has been more for the Byd overwhelming thrustthat he did not paint anything in 2020 and that from 2021 he experienced a vertiginous rise in the Chinese market. Byd’s success in Spain is also a reality, and it is because it follows the same tactic as Xiaomi: “bargain cars” that have surprising benefits for their price, at least if we compare them with those of traditional manufacturers models. And the tariffs not seem to impact. The European Union It has been since October 2024 Applying tariffs to the Chinese electric car, and vary according to the brand between approximately 8 and 35%. China Has a Trojan horse With its combustion cars in hybrids, but it does not even seem to be needed, because even with those tariffs the price/performance ratio of Chinese electric cars are still remarkable. At least, for now. The ecosystem is the key. As with Apple, Xiaomi not only wants to sell you a car, but they sell a complete ecosystem. Its electric vehicles are part of that ecosystem in which the mobile, home automation and xiaomi appliances are integrated. All an integration that no other manufacturer has achieved, but that Xiaomi has already well profiled. Let us remember what happened to mobiles. Xiaomi first focused on China and then Start an international expansion that many users were waiting. He triumphed with his baroteléphones for a few years, but ended up remarkably: for years he competes as one more in the high -end market – who tells them to Xiaomi 15 Ultra– And created two submarks (Redmi and little) so that they were the ones that offered more modest and affordable mobiles. It remains to be seen as its strategy with its electric cars. Image | Xiaomi In Xataka | Byd promised them very happy with his new plant in Mexico. He has just canceled all his plans

To win the AI ​​race, OpenAi wants the US to forget about laws. Specifically, those of Copyright

by

OpenAi is immersed in one demand seriesand all of them for the same thing: the alleged violations of the copyright that he has committed when training his AI models. Now a unique idea has occurred to get rid of all those problems. No copyright for AI. In one Proposal published by OpenAIThe company suggests the US government to consider a “copyright strategy that promotes the freedom to learn” and that “preserves the ability of American models to learn from materials with copyright.” Or what is the same: that copyright laws are not applied. IA companies have done what they wanted. We have been in which the demands for copyright rape to AI companies have been frequent. Companies that develop these models have shown no shame in this regard, and The funny thing is that there is still no consequences. What OpenAi now asks is that there are definitely not and that those works can work without legal concerns. China steps on our heels. The main argument to recommend something like that is to compete with more guarantees against China. The Asian giant has demonstrated striking advances, and in fact in Openai indicate how “although America maintains its leadership in Ia today, Deepseek It shows that our leadership is not broad and is narrowing. “ Fair use. As usual, the excuse of a “fair use” of the contents with copyright appears. According to the proposal: “If the developers of the People’s Republic of China have unlimited access to US data and companies, they run out of fair use, the AI ​​race will have finished. United States loses, just as democratic AI does. Ultimately, access to more data from the widest possible range of sources will guarantee greater access to more powerful innovations that provide even more knowledge.” “AI Action Plan” in sight. In January Trump revoked The Executive Order on the Biden He had signed In October 2023. Shortly after he issued a new one And he proposed an “Action Plan” that should be ready in 180 days. Openai’s intentions are that this plan includes such concessions. But the relationship with Trump is delicate. It is true that Openai is the great fencer with softbank of the Stargate projectand that is an initiative that Trump has presumed a lot. However, the relationship of Sam Altman’s company with the current president is complex, especially since Openai is In full legal battle With Elon Musk, the main advisor Trump. White letter. In Openai they seek to have white letter to train their models with works protected by copyright. Not only that: they also want to get their tools to help modernize government agencies being approved more quickly. Experts have not been warning that a too premature adoption of these tools could have dangerous consequences, for example in terms of possible leaks and information security. OpenAi commercialized Chatgpt Gov In January precisely with the idea that government employees had access to this type of services. China’s AI models should be revealed. The company’s proposal led by Sam Altman goes further and indicates that the AI ​​models of the People’s Republic of China are prohibited. According to them, models like Depseek They are “financially supported and controlled by the State”, and pose national security risks. Companies such as Microsoft, Perplexity or Amazon stay on their servers from the Deepseek service, but the data stay on US servers, so it seems difficult for the China Government to have access to them.
