problem

When a laptop’s battery began to smoke, an plane had to be evacuated. The problem is that it is no longer an isolated case

by

Airlines fear the flammable potential of devices Like Power Banks Or large laptops, and therefore establish capacity limits in batteries that can go on board in cab. A good example of the situations that seek to avoid we have had on an American Airlines flight, where a bag containing a laptop He started to smoke. What happened. While the shipment was carried out at the San Francisco International Airport (SFO) of flight 2045 to Miami, there was a small stampery with shouts like “fire in the rear.” The deceased was the smoke that came out of the bag of a passenger. The crew acted quickly, starting the evacuation of the aircraft and taking out the bag. What was done. The airline workers instructed passengers to leave the plane in order. However, as can be seen in a Video recorded insidethe hall became a chaos where passengers ignored one of the requests: leave bags, suitcases and other belongings in the cabin and go out empty. Some passengers left the plane with bags along the ramps, without following the rules. The evacuation ended without damage to the plane, but with three minor injuries. According to firefighters From the San Francisco Fire Department (SFFD), which confirmed that a laptop was the cause of smoke, the problem was born in its battery, without offering more details. Although before they arrived, smoke had already extinguished, firefighters introduced the equipment into a container with water to prevent future problems. What do protocols say. The European Air Security Agency (AESA) Establish clearly What to do as a passenger in an evacuation situation: Listen: Follow each and every one of the instructions on the cabin crew. Leaving luggage: “Trying to take your belongings will not only hinder you, but will also endanger other passengers. Luggage could hinder the exit and cause damage to the evacuation equipment” In the United States, process priorities They are exactly the same: follow the crew instruction and leave belongings behind. The objective is always that any aircraft is safely emptied in 90 seconds. A growing problem. Although since 2016 the lithium -ion batteries are prohibited in the wineries of the airplanes, the number of incidents related to them has shot themselves, either by smoke, fire or extreme warming. The Federal American Aviation Administration (FAA) carries A count And the figures are fully fired: between 2006 and 2016 there were 120 incidents. Between 2017 and May 2025, 377. More than triple cases, and in less years. The majority of incidents occur in commercial airplanes: 385 cases of 119 of transport aircraft. We have analyzed express mentions on fire in the descriptions provided by FAA, and there are 201 cases: 47 from 2006 to 2015, and 144 from 2016 to May 2025. And its solution during the flight. FAA incident records are also useful in another sense: they indicate how the crew mitigates the problems in full flight. The great key are “Thermal containment bags” as is from AvsaxThey are igniphed containers capable of sealing a device and preventing major disasters. In many cases, the crew chose to introduce the problematic device in water before moving to the protective bag. Airlines are taking measures, and for example Southwest Airlines already forces passengers who use Powerbanks to that they have them in sight while carrying. Why the batteries burn. If the question is why they explode, the answer is in a phenomenon, “Thermal leakage“: Overheating due to a heat production process that is self -demand, which ends up causing overpressure explosion. If the anode does not correct the cathode, there is heating, which leads to additional exothermic reactions, which overcome the chemical system and shape oxygen bubbles, CO2 and other gases. With luck, the reaction does not pass from smoke, but it is the precedent of something worse: fire. Why not everyone burn. Because of its characteristics, the batteries They occur following rigorous security plans. But nothing prevents batteries of worse quality or defective, such as Samsung confirmed for the Galaxy Note 7. There is also an additional factor that no longer depends on manufacturers: mechanical blows such as high -height falls, which can deform the battery and make different parts of it touch, which would cause a short circuit and contribute to heating.

Train liberalization in Spain has been a success for travelers. The problem is that companies are losing a money

by

Railway liberalization has reached cruise speed with spectacular results for passengers … but demolving for operators accounts. Why is it important. The train price war is changing the transport map in Spain. Users earn with more low options and prices, but companies are bleeding money in a battle that has also begun to question the sustainability of the current model. In figures: Almost 40 million travelers They used high speed in 2024. That is 77% more than in 2019, before pandemic. Prices They have fallen up to 42% On some routes. Passenger income is 35% below the levels prior to liberalization. The context. Ouigo has become the undisputed EY of low prices. In the first quarter it was the Most economical operator in four of the five liberalized runners: Madrid-Barcelona (18.59 euros). Madrid-Sevilla (29.09 euros). Madrid-Málaga (26.89 euros). Madrid-Aliante (20.80 euros). Only in Madrid-Valencia surpassed him Avlo, and it was for just 25 cents. This aggressive strategy It is giving results. The French subsidiary has managed to capture 36% of the market in Madrid-Aliante, 25% in Madrid-Valencia and 15% in Madrid-Barcelona. Yes, but. Profitability is another issue. The sources do not indicate the concrete losses of each operator in 2024, but The data They indicate that the average income remains far from the levels that Renfe achieved alone. The operators have increased only 6% the average income in Madrid-Barcelona, to the 8 cents per traveler and kilometer, a figure that remains 35% lower than the era of the monopoly. Deepen. Beyond numbers, liberalization is changing mobility habits. The train has won the battle to the plane bluntly: In Madrid-Barcelona, the rail share went from 65%to 81.5%, while other routes exceed 80-90%. And now the financial sustainability of the sector is at stake. If current margins do not allow long -term profitability, something will have to give in: either prices, or some operators will end up withdrawing from the market.

Europe has promised to spend 250,000 million dollars in US energy. The problem is that the USA surely does not have it

by

On the facade of the Turnberry golf course, between the Scottish Greens and the handshakes of hand, Europe and the United States They avoided a commercial war with an agreement that has been received with relief, but with considerable skepticism. As a headline, diplomatic victory sounds, but energy reality hides much greater complexity. The tariff pact. Donald Trump described the agreement as “the greatest of all”, announcing it from his Scottish resort. For his part, Ursula von der Leyen stressed that they had avoided reaching 30 %tariffs, which Washington had threatened to impose if an agreement was not reached before August 1. The agreement establishes a 15% tariff On European exports to the United States, accompanied by investment and import commitments that seek to “rebalance” a historically asymmetric commercial relationship. However, among the headlines a figure stands out: 250,000 million dollars annually in European Liquefied Natural Gas Purchases (LNG), Petroleum, coal and even US nuclear fuel. And there begins the problem. Does the United States have the capacity? The answer, As the journalist Clyde Russell has analyzed in ReutersIt is a clear “no.” In 2024, the total value of the United States energy exports to the European Union – including raw, gas, coal and refined products – was approximately 65,000 million dollars. To reach 250,000 million promised, they should quadruple. Even if Europe bought 100 % of US exports of crude oil, gas and coal – and no other country received a single drop of American energy – it would continue to be well below the objective. Russell He has described it As “an illusion”, comparable to the failed “phase 1” agreement between Trump and China in 2019, when energy purchases of 200,000 million were promised that were never fulfilled. So what is motivation? The explanation is more in politics than in logistics. The EU has preferred to avoid an escalation that threatened to paralyze its industrial exports, especially in sensitive sectors such as motor, pharmaceutical or semiconductors. As Columnist Pierre Briançon has explained in Reutersit is a “chapter disguised as success.” The new 15 % tariff multiplies by ten the previous average (1.6 %) and is not accompanied by equivalent tariff concessions by the US, beyond some specific sectors such as aviation or certain chemicals. Meanwhile, the European bloc also promises an additional 600,000 million dollars in direct investment in the United States during Trump’s mandate, including armament purchases. All this in a context of increasing tension by war in Ukraine, the dependence of NATO and American pressure on European technological regulations. From Moscow to Texas. One of the key justifications presented by Von der Leyen is that this energy turn reinforces European independence with respect to Russia. As pointed out in The Telegraphimporting US gas and oil will allow the continent “to free itself from Russian energy blackmail.” However, As several diplomats cited by Financial Times have pointed outThis also means a deeper dependence on an unpredictable and volatile trade partner. “Trump knows exactly where our pain threshold is,” an ambassador confessed to the British newspaper. In fact, it is not the first time that Trump threat directly to the EU with punitive tariffs if there are no immediate concessions. In addition, the London medium has detailed That the EU had a retaliation package worth 93,000 million euros, but was never activated due to lack of internal consensus. Germany, Ireland and Italy pressed to soften measures and protect national interests. Brussels’s “commercial bazuca” never shot. A word flies over: renewable. This energy turn also puts the European ecological transition under pressure. The pact does not mention concrete commitments in renewables, and on the contrary, Trump took advantage of the summit to load against wind energy, describing it as “the most expensive energy form” and a “scam”, As the Telegraph has collected. This raises a contradiction: while Brussels promotes projects such as Invest ai To create chips gigafactories and boost green digitalization, at the same time compromises astronomical sums on fossil fuels. A dissonance that, As the expert Mujtaba Rahman recalled in statements to Nyt“It reflects European concern for other geopolitical scenarios rather than for energy coherence.” Are they winning time? To ask ourselves, this is the first thing that comes to mind: it seems that Europe has bought time. Time to avoid immediate reprisals, to keep Trump moderately satisfied, and for the next administration – be it or not – redesign the rules of the game. A strategy that reminds the “Run the Clock” with which China sailed the 2019 trade war. Meanwhile, neither 250,000 million exist, neither gas flows yet, nor are the details closed. As The journalist Tim Wallace has summarized: “What seems like a tactical victory today, tomorrow can reveal its strategic cost.” Image | Unspash Xataka | The US has come to threaten Apple to manufacture the iPhone in the country.

The big problem of green hydrogen is the dependence of fresh water. We have found the solution in the sewers

by

In the great darking puzzle, Green hydrogen points ways to become one of the most important pieces. Has become one of the Great bets of the European Union For the Energy transitionbut although renewable energies such as solar or wind are used to produce it, it has a big problem: Consume a huge amount of fresh water. Some researchers want to stop this problem using something we produce in industrial quantities. Sewage. The water problem. Talking about clean energy implies looking at some initial point of the process to realize that there is still an ecological footprint. Electric cars do not emit, but make their batteries yesFor example. Something similar happens with green hydrogen. Solar or wind energy is which is used to perform the electrolysis process With which hydrogen is generated to use as a source of energy, but as we said, a lot of water is consumed, a resource that is increasingly scarce For millions of people. That is why we are investigating alternative ways to generate green hydrogen without those huge amounts of fresh water. For example, using seawaterbut there is a type of fresh water that had not been considered for the process and that has now entered the equation. Trash Treasury in wastewater. These waters contain a series of pollutants that, according to logic, would make it difficult to Electrolysis process. They have nickel, platinum, chromium and other metals that, until now, had to be extracted from water in an expensive purification process before using that water in electrolysis. However, a team from the School of Sciences of the Australian Rmit has found a way to take advantage of these metals to accelerate the production of green hydrogen. In electrolysis, electrodes are a key component because it is the one that facilitates the reaction that separates water in its base components: hydrogen and oxygen. To do this, an anode is used (where water breaks down releasing oxygen and electrons) and a cathode (protons earn electrons and form hydrogen molecules). In the anode and cathode metals such as nickel, platinum or iride are used as those found in wastewater, and what they have done from the RMIT is … take advantage of them. The invention. To do this, the electrode is manufactured with an absorbent carbon surface that attracts those metals present in wastewater, as if it were a magnet. When they “catch them”, form catalysts that conduct electricity and start that task of dividing water into its components. Nasir Mahmood is one of the researchers and, as we read in Miragenewsexplains the reaction as follows: “The catalyst accelerates a chemical reaction without consumed in the process, allowing metals to interact with other elements present in wastewater and enhancing the necessary electrochemical reactions to divide water into oxygen and hydrogen. And, beyond the theory, the team devised a device that managed They expose in ACSa stability of 95%. This pilot device, connected to a small solar plate, is the one you can see in the image that opens this article. And the waters look at everything … except purified water. Potential. Now, it is not as easy as taking the wastewater and using it directly. The team Confirm which used wastewater that had been subjected to some treatment to eliminate solid waste, organic matter and other nutrients. Not metals, yes. The water used for the experiment comes from agricultural waste, which opens another door to the circular economy of the materials. HE esteem that more than 80% of wastewater return to the planet without any treatment (although other sources They point at 50%), but if we started using a part to produce green hydrogen, we would be reducing that percentage, giving a breath to areas with drought problems and allowing to inject energy into those areas without affecting their Drinking water deposits. In developing countries it would have great potential. An upcoming step is to try more types of wastewater, since not all have the same amount of metals in their composition, and as professor Nicky Eshtiaghi, another of the authors of the study, comments, the plan now is to look for partners to climb technology and find commercial applications.

Openai has invested billions in chips. His only problem is that he has forgotten something important: cables

by

While Openai designs increasingly complex models and promises cities size data centers, a much more terrestrial reality threatens to stop the advance: the electrical infrastructure is not ready for what is coming. At the beginning of the year. Sam Altman (OpenAI CEO) promised, together with Oracle and SoftBank, an investment of 500,000 million dollars in AI infrastructure Under the name Stargate. The announcement, Made at the White House with President Trumphe talked about building 10 gigawatts of data centers on American soil by 2029. However, the start has been slower than expected. According to The Wall Street Journalnot a single formal contract with SoftBank has not been signed, and the first center, in Ohio, is still in the evaluation phase. Meanwhile, Openai has advanced on his own, expanding his alliance with Oracle to develop 4.5 more gigawatts, adding more than 5 GW under construction, As the company itself has reported. A big problem behind. This does not only affect Openai, rather the entire AI sector since no investment or quantity of GPUS can solve the true bottleneck of the sector alone: the electricity grid. As Le Monde explainedtraining models such as GPT-4 consumes dozens of gigawatts -hora, but the real challenge is in the “inference”, that is, in daily use. Each consultation to a model like Chatgpt implies complex calculations that consume energy every second. From the International Energy Agency (IEA), It was warned That the global electricity consumption of data centers could double before 2030, exceeding 945 TWH, more than all Japan today. And there the paradox appears: we can generate more energy, but we have no how to move it. In other words, high voltage lines, transformers, substations, adequate land, permits, technicians are missing. It’s like wanting to fill a city with bottled water, but without having pipes. The project continues. In a last statementOpenai has affirmed that its expansion with Oracle is already creating tens of thousands of jobs in Texas and that the objective of the 10 gigawatts is on its way to being surpassed thanks to new alliances. The Stargate I site, in Abilene, has already begun to operate with NVIDIA GB200 chips. However, As the Wall Street Journal has detailed, Disagreements with SoftBank persist on where to build, how to finance and how to connect data centers to electrical networks that are already saturated. Sam Altman recognized the challenge in an internal memorandum cited by axios: “The thirst for computer science is beginning to tension the supply chain and demands some real creativity.” Other paths: atomic energy. Faced with these limitations, technological giants are looking for solutions outside the traditional electrical system. The answer, for many, is in a surprising return: nuclear energy. Goal has signed a 20 -year contract with Constellation Energy to supply part of its data centers from a nuclear plant in Illinois. Google and Amazon They have also opted for small modular reactors (SMR). Microsoft, meanwhile, will reopen a closed nuclear power plant since 2019exclusively to support your AI infrastructure. Nvidia has not been left behind. In 2024, it invested 650 million dollars in Terrapower, the company founded by Bill Gates that is building the first Natriat reactor, a fourth generation machine that, According to their developersIt will generate electricity by half of the cost of a conventional reactor. The project, which takes place in Wyoming, has a Spanish participation: the public company sees the reactor cover. Without cables, there is no ia. Meanwhile, the number of users continues to grow. Chatgpt reached 800 million active users in April, According to Altman cited in axios. Each of them generates requests, questions, images, instructions, and all that consumes energy. According to Le Mondetasks as simple as writing an email can be more than 7% of a complete mobile phone charge. And generating an image consumes even more. Elon Musk says his company XAI already operates with 230,000 GPUS, and expects 550,000 more. The AI does not rest, but the cables that feed do not supply. Artificial intelligence promises to change the world, but before it will have to face something more basic than any algorithm: the physical laws of electrical systems. There is no needless. There are no servers without energy. And there is no energy without cables.

A video game is recruiting the brightest minds of Russia for war. The problem is that they still go to school

by

Russia gave a blow this week revealing a video of a few minutes. In it, the interior of what they have called as “the largest secret factory of combat drones on the planet”, located at some point in Alabuga, in the Tartaristan region, was prisoned. The piece showed us a huge army of drones with their workers assembling the pieces. However, there was something else: most were not adults, They were teenagers. A video game and a war. History is part of an investigation and exclusive to Russian media in exile The Insider. Apparently, since the summer of 2022, under the appearance of an educational and entertainment platform called Berloga (“Bear Dirridge”), Russia has been recruiting hundreds of thousands of schoolchildren in a progressive technical-military training system focused on the development and use of drones, camouflaged after video gamescompetitions and programs with academic incentives. The game, approved Personally by Putin And symbolically presented in the busy city of Sebastopol, introduces children into a children’s narrative in which “smart bears” They defend The vital resource of “bees” insects, a barely concealed allegory where bears are Russia and Ukrainian bees. From the first levels of the game to participation in face -to -face competitions and the physical assembly of drones, children are guided along a route designed to transform them In technicians and operators useful for the Russian military complex, all while assures them that “they should not say that it is for war.” From command to the welder. Berloga is not an isolated initiative, but the entrance door to a broader educational network built by the so -called agency for Kremlin strategic initiatives, in which They converge NTI Technology Clubs, the TALANT student achievement monitoring platform and the national archipelago intensive. These programs are connected to each other through competitions As great challengesin which thousands of students work in solutions to “technological” problems (which often have undercover military purposes) proposed by companies associated with the Russian State. Screen capture of the concept of a superpesado launch vehicle with a water -based launch system from the “Large Challenges” program Privileged minds to war. He counted the medium That the students who stand out are rewarded with extra points in the national exam, presidential scholarships and direct entries in companies in the defense sector, such as Geoscan, Yakovlev or Almaz-Agent. The tasks presented to them range from the Improvement of the navigationN from UAVS to the design of unmanned vehicles launched from floating platforms, through automated drone detection systems and laser loaders for tactical use. Although J is requiredUstify the projects As if they were for civil use, the students themselves admit That it is a formality: the real objective is military. Children engineers. Adolescents who participate in these training skills and networks not only program or design prototypes, but some (related to research for themselves) They train soldiersthey set up FPV drones and work to undercover military laboratories in exchange for contracts by work with the consent of their parents. The components they use in the contests are the same as they then use in the operational versions of their creations. In other words, knowledge flows directly to the front. Dual technology. In one of the cases, a young man named Stas developed a kamikaze drone low cost to replace current models of the Russian army whose price exceeds $ 10,000 per unit. Another, Vladislav, collaborated with a state company for Test war teams electronics about its own air platform. Companies, Like Geoscan or Yakovlev, segment their operations between civil and military branches, a common practice that allows maintaining the legality facade against international sanctions. This structure of “dual technologies” is held by officials such as Vice Minister of Commerce Vasili Shpak, who argues that there is no longer a clear distinction Between the civil and the military. The official narrative line points to a future in which all technological innovation will be automatically usable for the war conflict. A photo of the Official Telegram Channel of Zarnitssa 2.0 Child Military Training Child involvement in these programs goes beyond technical learning. Here it seems Intensive archipelagowhich in its beginnings covered various sectors, and has been reconverted in an almost exclusively drone course. Includes exercises like Recognition, electronic evasion, drone launch from land stations or search for objectives with thermal cameras. In parallel, Berloga allied in 2024 with Zarnitssa 2.0the modern version of a Soviet military game. The program, financed with millions From rubles of the state budget, he has trained tens of thousands of schoolchildren between the ages of 7 and 21 In the use of weapons Compressed air, Wannera-47 rifles massers, drones flight and choice of military specialties such as Zapador, UAV operator or political instructor. Discrepancies. Some schools are They have complained that both students and teachers have been forced to participate. Zarnitsa It is managed For the Yunarmiya Youth Movement (Young Army), linked to the Ministry of Defense and that in 2025 will receive More than one billion of rubles in subsidies. For the Russian authorities, the objective It seems clear: Detect military talent from an early age and channel it to the defense industry. War pedagogy. There is much more, since research emphasizes that this mass and silent recruitment of minors for war purposes is being institutionalized with Explicit support of the Kremlin. Putin has ordered drone competitions for children since the age of 7, and new school subjects Centering national security include training with UAVs. The official goal is to achieve “technological sovereignty” by 2030, and today’s adolescents are expected to become the military operators of tomorrow. Officials such as the Deputy Minister of Education Dmitry Afanasyev defend The formation of children in military technology under the pretext that “there are no purely civil applications.” In His wordseven a agricultural drone operator You must have combat competitions, as in China. Thus, Russia is institutionalizing a war pedagogy where the child ceases to be a citizen in training and becomes an anticipated military resource. Rights of the … Read more

What Spacex has achieved with Starship is incredible. The only problem is that he has done it at the expense of the health of his employees

by

Spacex has no paragon. The speed at which it assembles its rockets, the tests and itera in its design is far from the competition. But it comes with a hidden cost: a rate of injuries that multiplies by four of its rivals and reminds the security figures of 30 years ago. Context. Starbase is the Starship operations basethe place where the Aerospace Company of Elon Musk manufactures and proves the gigantic Rocket Starship with the ambition to launch thousands of ships to Mars in the coming decades. Although the program has achieved unthinkable technological feats, its frantic rhythm and its vertiginous deadlines are having a high human cost, especially if the risks assumed by Spacex are compared with the usual caution of the space industry. Six times more work accidents. Official data analyzed by Techcrunch They reveal that Starbase suffers six times more occupational accidents than the industry average, which makes it the rocket factory with the highest risk of injury in the United States. The Spacex headquarters registered a rate of injuries that multiplies by four of its rivals and resembles the figures of 30 years ago, when the security protocols were more lax. The figures are public. They leave The database of the United States Occupational Health and Safety Administration (OSHA) and use a standardized metric: the total rate of registrable incidents (TRIR), which calculates the number of injuries in one year per 100 full -time workers. Are public data that Spacex is obliged to report. And they are overwhelming. Starbase’s trir in 2023 was 5.9. That is, for every 100 employees, there were almost six recordable injuries. In comparison, the average of the space vehicle manufacturing sector was 0.7. And the average of the entire space sector was 1.6. A 30 -year setback. Although Starbase’s trir improved 4.27 in 2024, it is still a fact comparable to that of the sector 30 years ago. In 1994, the average trir was 4.2. In Starbase, with 2,690 employees in 2024, more than four injuries per 100 employees was 3,558 days of work with restrictions and 656 days of low labor. Anomalous even within Spacex. Starbase is not only a black point compared to the rest of the industry, but also within Spacex itself. None of the company’s facilities approaches the figures in southeastern Texas, with the exception of risky rocket recovery operations on the high seas (with a 7.6 trir). While Starbase registered 4.27 in 2024, the Falcon rocket factory in Hawthorne (California) recorded 1.43. A figure closer to that of competitors such as Blue Origin (a 1.09 in its Florida factory) or United Launch Alliance (1.12 in his Alabama factory). On the other hand, Starlink Terminal Factory in Bastrop registered 3.49, the Redmond satellit factory registered 2.89, the McGregor engines factory recorded a 2.48. Move fast and break things. Elon Musk’s philosophy works when applied to rockets, but squeaks when applied to the safety of his workers. What does Musk say? That the traditional media lie. Or at least that said when Reuters published that Spacex had not declared injuries that included amputations, crushed members and a death For a burst of wind that launched a worker from a truck. What does NASA say? NASA contracts with Spacex They include specific clauses that would allow the agency to intervene in case of a “serious security violation”, as a “repeated” sanction by the OSHA. The high trir rate, alone, is not enough to activate these clauses. Image | Spacex In Xataka | Starbase residents voted to be the city of Spacex. Now a letter has reached the right to their property

You have the solution ready before the problem appears

by

Nvidia is where it is by chance. Just two weeks ago the company led by Jensen Huang reached a capitalization value of 4 billion dollars. It is the first company in history that materializes this milestone. Largely His overwhelming success of recent years It is the result of the privilege position it occupies in the hardware industry for artificial intelligence (AI) with a global market share higher than 80%. However, to find the authentic reason for its success we have to go back to its origins. According to Tae Kim, the author of the trial book ‘The Nvidia Way’this company continues to compete today thanks to two qualities of Huang: its perseverance and its intuition. Thanks to them, he managed to overcome in 1998 a crisis that He was about to end Nvidia. And thanks to them this executive has developed a surprising capacity of anticipation. Nvidia has trouble making the H20 GPU, but the solution is on the way ‘The dilemma of innovators’ It is one of Jensen Huang’s favorite books. The ideas that Clayton M. Christensen exhibited in 1997 have helped him not only to place his company in The privilege position that currently holds in the technology industry; They have also allowed him to keep it at the top of success for more than two decades. And, above all, they have taught him how to anticipate the blows and how he can prepare to fit them. The last one received it in April. And is that in the middle of that month the US Department of Commerce imposed new restrictions to the export to China of the GPU for AI H20what in practice caused this chip to stop arriving at the Chinese clients of this company. This news Nvidia’s shares sank 6% in the bag because I could no longer attend the commitments linked to the H20 GPU that it had acquired. Among the Chinese clients who had bought great amounts of this GPU, and who presumably planned to continue doing it, were Tencent, Alibaba or Bytedance. The most advanced TSMC manufacturing lines have a very high demand and there is an endless waiting list Finally, like We explain to you on July 15Nvidia has made the Department of Commerce review its regulation and allow you to sell the H20 GPU in China again. “The US government has assured us that licenses will be granted. We hope to start deliveries soon,” Pray a statement from Nvidia. But, once again, this company has stumbled upon a problem. When the Trade Department restricted the export of the H20 GPU, Nvidia asked TSMC to stop the manufacture of this chip. It is normal. It was expressly designed for the Chinese market and was not going to be able to continue selling it in China. Now resume large -scale production of the H20 GPU in the TSMC nodes is a problem because the most advanced manufacturing lines They have a very high demand And there is an endless waiting list. A priori this scenario could be a hard blow for Nvidia because it would prevent him from serving his Chinese clients, but the solution has been on his way for many months. And it is that the company’s engineers have been working on A new GPU with Blackwell microarchitecture The latest generation that is intended to occupy in China the place of the H20 chip. In fact, presumably TSMC began in June the production of The B30 GPUwhich is how it seems to be called. What we know at the moment is that this chip for AI will be less capable than the H20 GPU, as is logical, and also that its price will move between $ 6,500 and $ 8,000. For domestic users it is a lot of money, but in the field of professional GPUs for AI it is a moderate price. In fact, the H20 GPU costs between $ 10,000 and $ 12,000.

We have detected the greatest fusion of black holes seen to date. It is a problem for our theoretical models

by

One of the enigmas that most intrigue astronomers is that of Black holes of intermediate size, those black holes halfway between the holes of stellar mass and the supermassions such as the one that dominates in the center of our galaxy. These are black holes with masses between 100 times that of our sun and those that multiply this star mass by millions. GW231123. A group of Ligo-Virgo-Kagra (LVK) collaboration researchers (LVK) has announced The detection of the greatest clash between two black holes registered to date. The discovery has occurred thanks to the gravitational waves generated by the impact, whose signal has been called GW231123 by those who detected it. November 2023. The name of the signal refers to the date on which it was observed, on November 23, 2023. The study of the detected waves led those responsible for the new study to estimate that the resulting black hole had a dough some 225 times higher than that of our sun. Until now the most massive had been “alone” 140 solar masses. It was in 2021, the GW190521 signal. Estimates indicate that the 2023 signal was the result of the collision between a black hole of 100 solar masses with one of 140 solar masses. That is, only one of the black holes was already as massive as that of the fruit of the largest shock detected so far. From this event not only highlights its magnitude, but also the fact that the speed of rotation of black holes was surprisingly high. A new enigma in heaven. All this planet an important unknown for the team. As they explain, the holes of such mass cannot be formed from the death of a star, at least based on what contemporary physical models say. The only way we know can be formed is through the fusion of smaller black holes. LVK. In 2015, the Ligo experiment made history detecting for the first time the clash of two black holes through the expansion of gravitational waves associated with such a violent event. This pioneering experiment has been company in Europe and Kagra for years (Kamioka gravitational wave detector) In Japan. Together they have already detected more than 300 clashes between black holes. The details of the study They have been presented In the 24th International Conference on General Relativity and Gravitation (GR24) and 16th Conference Edoardo Amaldi on gravitational waves, a joint conference held this week in Glasgow, Scotland. Not so easy to observe. The detection of GW231123 “pushed the limits of both gravitational wave detection technology and current theoretical models,” says the responsible team. Analyzing these types of events through gravitational waves is not easy, but knowing more about them can help us unravel some key mysteries of the cosmos. “Black holes seem to turn very quickly, almost to the limit of what is allowed by Einstein’s theory of relativity,” explained in a press release Charlie today, co -author of the study. “This makes the signal difficult to model and interpret. It is an excellent case study to push the development of our theoretical tools.” Looking for the midpoint. Theoretical tools that perhaps help us reveal the secrets of the elusive black sized black holes. Today we do not know very well how these holes are formed whose mere existence implies the certainty that we still do not know about our universe.

The big problem of marine wind is cables. Germany has a plan to avoid them

by

In the middle of the North Sea, an anchored barge off the German coast does not transport merchandise produces fuel. It is not science fiction: it is the first floating floor that converts wind, seawater and air into energy for the future. Short. In the port of Bremerhaven, Germany floats a rare platform. At first glance it looks like another industrial barge, but in reality it is a floating laboratory that prepares for something unpublished: to manufacture synthetic fuels directly in the sea. More in depth. The project His name is PTX-Wind and is part of the national H2Mare initiative, focused on the production of clean energy on the high seas. It is promoted by the Institute of Technology of Karlsruhe (Kit), together with the German Aerospace Center (DLR) and the Technical University of Berlin. The installation has not yet left the port, but it is already ready for its next phase: operating in real conditions against Helgoland. The purpose of the kit with this test is clear: show that e-combustible in the high seas can be generated, without electricity or land infrastructure. No cables, network or land firm. One of the most striking things of this platform is that it is not connected to any electricity grid. It works totally autonomously, using only wind energy, seawater and the surrounding air. What you get from there transforms it into liquid fuels ready to use, without net emissions of CO₂. According to Professor Roland Dittmeyer, director of the Institute of Microprocess Engineering of the Kit and project coordinator, this installation not only seeks to demonstrate the technical viability of the system, but also learn to climb it for future large industrial platforms. The heart of the barge. Inside, this platform integrates several advanced technologies that, together, form a Power -to-X (PTX) chain (PTX). In other words, they convert renewable electricity into fuels or other chemicals. The giant laboratory has a first phase of Direct air capture (DAC)which extracts carbon dioxide directly from the atmosphere. After that, desalination to transform seawater into water suitable for electrolysis. That water is divided into hydrogen and oxygen using electrolysis fed by wind energy. Finally, a synthesis is used Fischer-Tropsch to combine hydrogen with CO₂ and generate liquid hydrocarbons, also known as e-combustible. The entire system has been designed to operate in a modular, flexible and disconnected way of the electricity grid, adapting to the natural intermittency of the wind. This allows maintaining active production even in variable conditions, a key aspect for its replication at an industrial scale. First in your class? While there are other hydrogen production projects on land or offshore wind platforms, none until now had gathered all these pieces in a single floating and autonomous structure. According to Interesting Engineeringthis is the first plant that converts marine renewable energy into liquid fuel without depending on the mainland or electrical networks. The point is that not everything can plug. Today, many sectors already advance towards electrification: cars, heating, even some trains. But there are industries – as aviation, maritime transport or heavy chemistry – that still depend on liquid fuels with high energy density. The e-fuels, like those produced by this platform, They are a neutral alternative in carbon that could replace diesel or kerosene without the need to completely redesign airplanes or ships. And the best: they do not compete for agricultural lands nor consume fresh water. When operating directly in the sea, they take advantage of the wind potential and avoid costly terrestrial infrastructure. According to the Federal Ministry of Investigation of Germany (BMBF)also helps relieve pressure on local electrical networks. Not only diesel. Although for now the main objective is liquid fuels, the team behind PTX-Wind is also investigating other possible production routes, such as Synthetic methane (compatible with current gas networks), The green methanol (useful for maritime transport or chemical industry) and renewable ammonia (It works as a hydrogen bearer or as fertilizer without emissions). The sea as a new energy border. More than a prototype, the PTX-Wind platform represents a scalable and adaptable model for the production of fuels in the high seas. Its modular design would allow to replicate this technology in different coastal areas of the world, creating a distributed network of floating refineries of clean energy. At a time when climatic solutions are urgent and promises often stay on paper, this floating barge is a tangible example that innovation is already out there, literally floating in the sea.
