Chinese mobiles have batteries 11% higher than those in the rest of the world. The culprit is called sic

by

Chinese smartphones have a clear advantage: their batteries are 11% larger than those in the rest of the world. A consolidated suspicion that is now measured thanks to Counterpoint Research. The average in China reached 5,418 mAh in May 2025, compared to 4,900 mAh in the rest of the world. The difference has expanded to exceed 500 mAh in recent months. Why is it important. China is adopting carbon-silicio batteries (sic), a technology that allows greater energy density without increasing the thickness of the device. The rest of the world maintains more conservative technologies even though Two years ago we warn of this impact. The context. Chinese brands have opted to solve one of user’s biggest headaches: autonomy. With larger screens, more frequently soda and applications that consume more energy, including Local generative AIThey need more capacity. 6,000 mAh or more mobiles already represent 35% of the Chinese market, compared to 9% of a year ago. OnePlus leads with the greatest average capacity thanks to Your Ace series, exclusive to China. There is a revealing pattern: brands such as Honor, Huawei and Vivo launch models with larger batteries specifically for the Chinese domestic market. But their global versions maintain minor capacities. Why does this happen? Because China is its test laboratory: SIC batteries certifications are more agile there. In China you can try that technology before facing the expensive and slow western approval processes. It is cheaper to try at home than to risk out with a new technology. And now what. China will maintain this short -term advantage while Western brands wait for SIC technology to mature. The gap will be reduced when more manufacturers adopt large batteries as a global differentiation factor, and not only in China.

Ouigo excuses himself from the collapse in the bird and believes to know who is the culprit

by

They were “13 hours trapped in the middle of a plain”. And, since then, the Government, Ouigo and Adif are trapped in a major battle. Specifically, to find a culprit to the collapse of high Andalusian speed last week. Thousands of affected travelers, many unknowns and only a safe thing: nobody wants to peeled. “A Sinking”. “How to attribute responsibility in the sinking of a road to stuck cars, something frequent and habitual.” This is how Ouigo has described in a statement, collected by Europa Pressthe report derived from the collapse of the high speed that was lived on June 30 when hundreds of travelers from the Andalusian corridor their trains were stopped But, above all, when the passengers of one of those trains spent the night in the bird, No water and without being rescued. That report has elaborated Adif And he points out that an Ouigo train was to blame for the collapse of the network. According to the infrastructure manager, the French company train “lost the check with the signal systems standing on the road.” That caused four other trains to stop, causing the dominated effect already conspired. Adif points to Ouigo … The report, collected by The worldHe points out that the French train stop accumulated up to five trains in seven kilometers of tracks. The manager explains that the catenary tension is designed to feed a train in motion but not to keep five trains active at the same point. In that case, there is a risk of over -overtime. When this happens, the train is disconnected from the catenary to avoid greater risks but causes a tension drop in the line. It is something like lowering the leads at home so that appliances do not shrink with a voltage rise. The whole system is controlled by the pantograph. This manages the electricity between the train and the catenary and is the one that is supposed to be in the Avant de Renfe that remained in the middle of nowhere. That is, Adif points to Ouigo as the seed that ended up creating chaos. … ouigo blames Adif … “This cannot be used as an alleged cause of the tension drop in the catenary. The infrastructure must normally contemplate this type of situations.” Ouigo said in the aforementioned statement to subsequently underpin the phrase with the previous metaphor. The company emphasizes that Alstom’s MEPs, the trains with those operating in Spain, are one of the “most reliable and insurance models in Europe” while emphasizing that they will collaborate in any request for information that is requested from ADIF to clarify what happened. … And the government puts the eye in ouigo. The mention of trains safety is not accidental. Last Wednesday (July 2), at a meeting between Addar and the PSOE, María Jesús Montero, Vice President of the Government and Minister of Finance, was hunted by an open microphone. There he could say that the maintenance of “the ouigos these” was not correct. “We from Renfe remove them, which do not remove the trains from the tracks,” Montero was heard to tell various representatives of adding, in words collected by the media, among which is 20 minutes. “Apparently there is a problem too, well, of those operators, and I plan to raise it. I do not know if there is a certain sabotage, I cannot understand it, I am a user of that bird, it is my usual means of transport,” Montero insisted. More investment with canons flying In addition to defending themselves, from Ouigo they have insisted to Adif on taking into account their demands of greater investment in the maintenance of the infrastructure. They point out that the situation lived last week is “unpublished and unacceptable”, in the words of Helene Valenzuela, CEO of the company in Spain, during the IV Mobility Forum organized by The economist. They ensure that the projected image directly affects high speed and believes that The ADIF Plan It is not enough because “you cannot identify all the weak points of the network.” That is why they demand a greater investment at the time that the canons that the manager wants to apply to the operators for the use of the infrastructure. Until now, Ouigo has pointed to the canons as the main reason why they are not profitable on their arrival in Spain. That absence of profitability has been denounced by the Government who even warned that would denounce Ouigo against Europe for unfair competition.

A strange night a whistle has been listening for weeks in Vigo. They just found the culprit

by

There are phenomena whose sounds They challenge not only reason, but even the very perception of reality. One of them is remembered in Scotland Since the late 90s, a low frequency buzz that is heard in different enclaves and that in recent times he has returned strongly. In Spain something similar to this part happened in an area of ​​Vigo. Weeks with acute noise when the night that had altered the dream of the neighbors. The problem is that they have just detected the “guilty”, and has a difficult solution. The mystery had wings. It The Faro de Vigo had. For weeks, the neighborhood of Vigo’s journey and Aragón Street has lived in confusion and irritation because of an acute, intermittent and persistent beep that began at nightfall and repeated every two or three seconds until dawn. The initial suspicion fell to multipable guilty: a spoiled alarm after the blackout of April 29, a port of the port amplified by the wind, or even some damaged traffic light out of decibels. The neighbors, unveiled and perplexed, mobilized to find the origin of the annoying sound, called 010, patrolled the streets in search of sound tracks and requested the intervention of the local police. In the end, neither industrial alarms nor port machinery: the author of the beep has turned out to be An unexpected creature and surprising, whose presence had gone unnoticed until then because of its historical silence and its expertise for camouflage. Small and nocturnal. Yes, apparently, the Local Police, after inspecting the area and confirming that it was not any mechanical source, identified the person in charge: a European autillo (Otus Scops), one of the smallest raptors in Europe (does not exceed 20 cm in length or 100 grams of weight) whose song remembers a high frequency electronic whistle. In fact and how I told the middle The biologist of SEO BirdLifeGustavo Ferreiro, the repetitive beep is part of the AVE mating ritual, which is in this time in an incubation phase. In other words: the autillo does not sing to bother, but to communicate its presence, claim territory and maintain the link with your partner during the breeding. Invisibility. Although common in southern Pontevedra, his nightlife and his perfect camouflage among the trees make him an almost inhabitant invisible which can only be detected by your voice. In this caseHabitat’s choice was an urban environment with dense vegetation and old trees, which surround the Matías Park and a nearby abandoned house. European Autillo Survival paradoxes. The case also offers other readings. The paradoxical is that The European Autilloonce a rural bird, it is today forced to take refuge in urban environments due to the loss of biodiversity In the field. Agricultural intensification has eliminated large trees, essential for nesting, and the massive use of pesticides has decimated insect populations that are fed. Thus, the natural habitat has degraded to such an extent that birds seek shelter in urban parks, where they can still find cavities and some food. This forced migration to the city is a reflection of the ecological decline in which the species is found, already included in The “vulnerable” category In the Red Book of the Birds of Spain 2021. Thus, the presence of the Autillo in Vigo is not an isolated anomaly, but rather a symptom of a deep change in the distribution and behavior of many species affected by human pressure on ecosystems. Endangered species. The case of the beep in Vigo demonstrates how a daily discomfort can actually be the life sign of an endangered species. What began as a sleep disturbance became an opportunity to reflect on coexistence between the city and nature. The case reminds others where the presence of cities ends up modifying the life of species. In fact, in Valencia something similar has happened With another copy. EITHER In Icelandwhen the frailecillos season begins and humans hunt them and throw them through the cliffs (by A good reason). In this case, climate change and cities lights threaten the survival of birds. With the autillo, the loss of biodiversity is what is throwing them into such Obern Like cities. That said, and if everything follows its course, the song will send for the neighbors in August, when the chicks and the priorities of the bird change from the courtship to the care.

North Korea was going to throw his greatest war boat and ended up sinking it into the sea. Everything points to a culprit: Kim Jong-un

by

Making a fool of it is something that It is not anyone’s pleasure. Surely you have ever stumbled down the street and looked around to see if someone had seen you. Now, imagine that what stumbles is a Military ship of 5,000 tons and several million dollars and sinks at the time of its premiere. That is what happened last week when Kim Jong-un He witnessed how His brand new war ship sank before the impotence of all those present and under the watchful eye of the rest of the planet. And everything indicates that the error was because, as the Spanish proverb points, the hurry are not good. Short. Days before the event, satellite images They showed both the vessel and a scenario in which what seemed to be an observation zone. Probably, the place from which Kim Jong-un was going to witness that historic moment. And the truth is that it was historic, but not for the reasons he would have wanted. On May 23, during the launch ceremony of the new North Korean destroyer (the second of its most advanced class), all attendees in the front row and the world was witnesses of a Technical failure that ended in disaster: the ship overturned. That symbol of power, with 143 meters in length and 74 vertical missile launch cells, ended up ridiculous. How do we float it? Satellite images later Analyzed by the Center for Strategic and International Studies, or CSIS, they showed the ship partially sunken with tarps that covered the disaster. And, although at first the rush was blamed, we now have more clues about everything that could go wrong. Obviously, there is no official information from North Korea, but in The New York Timeswe can see that there are analysts who are quite clear what the problem was. Or the sum of them. Image | CSIS/BEYOND PARALLEL/MAXAR When a ship is finished, there is Several ways to ‘throw it’ into the water. We have the sliding launch in which the ship slides on a ramp into the water. The dry dock in which the ship is built in a dry dock and, once finished, the water dike is filled (That is done with cruises). Also the mechanical launch by cranes, the launch with airbags that are placed under the ship and allow it to slide to the water. And the side launch that drops the side ship into the water. Normally, a single technique is used, but in the North Korean destroyer disaster it seems that sliding and side techniques were used. And not because that’s how it was planned. Perfect storm. As noted The New York TimesIt was the first time that analysts watched North Korea use the side launch to throw a war ship. This technique is sure if it is done well, but in Large ships It is more likely that a problem appears, with dire consequences if it happens. The reading of the analysts is that, using that technique for a 5,000-ton ship points to a lack of experience added to the political pressures by Kim Jong-un to achieve rapid results. The destroyer was manufactured in the port city of Chongjin that has experience assembling ships of such magnitude, but not something as huge as this ship. This puts on the table that a possible trigger was that inexperience When throwing such large ships. In the absence of a dry dike of the appropriate size, it is estimated that the engineers tried the lateral launch to throw it into the water, but the angle was not correct and, when trying to slide it, the ship was unbalanced and ended up lying on the right side. When it goes well, as happened with this fighting ship of 3,500 tons in 2013, it is worth seeing: And it can also go wrong: The hurry are not good. Interestingly, this destroyer is from Choe Hyun classwhose first model was inaugurated successfully Last month. It was going to be the second great frigate of North Korea and the new example of that naval remodeling that Kim Jong-un is promoting. And the precedents were good: the first It was built In the city of Nampo and, because it is a larger shipyard, they could put it afloat through the technique of dry dock. There were no major problems and, at the inauguration, the ruler saw how test missiles were thrown successfully. However, there are hurry in the government dome to follow demonstrating to the world its military potentialwhich has led the president to visit the shipyards who are building new ships to accelerate delivery deadlines. In addition, there are information They point out that, although the ship could have thrown out correctly, the ocean exit street is narrow and has a questionable depth. I made a. pic.twitter.com/urflog6leo – Dr. Jeffrey Lewis (@armsControlwonk) May 22, 2025 Firm hand. And who will pay for this? At the moment, the ridiculous has resulted in several arrests of members of the responsible shipyard itself. The Central News Agency of Korea reported that the chief engineer, a senior armament official and another member of the installation had been arrested, and Kim himself described The accident as a “criminal act”, demanding An urgent restoration of the ship before June. Country engineers estimate that, pumping seawater, they can straighten the ship and repair damage. And it will take about ten days to do it, but it seems complicated because, after a week, Keep as it was. Sentinel-2 images of May 23 and 28. Despite the clouds, we can see that the destroyer continues exactly at the same point And sarcasm. From South Korea, which always have an eye and a half placed in what their neighbors doThey think something else. Yang UK is an expert in North Korean military affairs of the Asan Institute for Policy Studies in Seoul and, as Tnyt comments, the incident may not be only an accident, but something caused by a structural imbalance on the ship itself. … Read more

In 2021 Texas stayed in the dark for days. Politicians blamed the wind, but the culprit was an old acquaintance

by

The story occurred in February 2021when a historic winter storm that affected much of the state of Texas generated the last great electric blackout. Between February 13 and 17, extremely low temperatures and adverse weather conditions caused the disconnection of more than 4.5 million homes and business, some for several days. The event is considered one of the blackouts more serious in history Modern of the United States, so much that politics tried to take advantage of the “guilty.” The mirage of the wind. As we said, in February 2021, Texas lived one of the most serious energy crises in its modern history, when a winter storm paralyzed a good part of the state, causing massive power cuts, dozens of deaths and extreme conditions that affected millions. In the midst of chaos, the governor Greg Abbott appeared on national television (in Sean Hannity program, in Fox News) to directly hold the renewable energies of collapse, and especially wind. In a sharp statement, he said that the ruling showed that the State and the country continued to need fossil fuels to guarantee the winter supply. However, the accusation, repeated by other leaders conservatives and related media, not only It was wrong but deeply interested, because the data showed that the main person in charge of the collapse had been … Natural gas, not the wind. The Texas Network and its fragility. Texas has a unique electrical grid, known as Ercot (Electric Reliability Council of Texas), which operates almost independent of the rest of the national network. This deliberate disconnection, designed to avoid federal regulations, also prevents the State from importing electricity easily in case of emergency. Thus, when temperatures fell dramatically in February 2021, many electric plants (especially those fed with natural gas) They were not prepared To operate in freezing conditions. The pipes froze, the valves failed and gas production collapsed, just at the time of greatest energy demand. Although some wind turbines also froze, their weight on the network was relatively small: about 7 % of the production planned for that time of the year, according to expert calculations. Most cuts came from thermal and nuclear plants that could not operate due to lack of fuel or technical problems derived from extreme cold. Politics in a blackout. Despite this evidence, the narrative that was quickly imposed in conservative sectors was that the ruling had been caused by clean energy. From Fox News to the Wall Street JournalHE They multiplied the voices that ridiculed the renewables, called them “non -reliable” and demanded a return to coal -based energy. An old ideological campaign against environmental policies was reactivated and, in particular, against the Green New Deal promoted by some Democratic legislators. Even false images were shared, such as a photograph of frozen turbines supposedly in Texas that It turned out to be from Swedencaptured years ago during a thaw test. Social networks, media and politicians such as Congresswoman Lauren Bobert or state senator Mike Thompson They spread without contrast Uninformed arguments that placed wind and solar energy as guilty of the blackout, reinforcing a rhetoric that had been downed long before the incident. The response of experts. Numerous researchers and electrical systems specialists They denied the official version repeated by the governor and other leaders. Jesse Jenkins, engineer of the Energy System of Princeton, summarized in a phrase What happened: “All generation sources are being beaten.” Indeed, freezing affected both gas and coal, nuclear and renewable plants. The problem was not a single technology, but the lack of preparation of the infrastructure set in the face of extreme weather conditions. Leah Stokes, political scientist at the University of California in Santa Barbara, The irony stressed to New York Times of the situation: the same fossil fuels that were feeding climate change were those that had failed in an increasingly common weather scenario. From that prism, what did not support the system was not renewable energy, but an obsolete network model, little resilient and possibly more focused on economic efficiency than in climate emergencies. Climate change as a backdrop. Plus: the crisis occurred just when Joe Biden came to the presidency and had signed his First executive orders In climatic matters, reincorporating the United States to the Paris Agreement and canceling the Keystone XL pipeline. Under that context, the Texas blackout became a discursive battlefield between those who asked for more investment in clean energy and resilience, and who defended the continuous and reinforced use of fossil fuels. Biden had made it clear that his vision went through Modernize infrastructure Energy of the country, generate green jobs and reduce emissions towards a zero net target in 2050, but the storm served the opposition sectors as excuse to discredit said agenda. Broken system Far from demonstrating an alleged “uselessness” of wind energy, the Texas blackout In 2021 it was a more warning about the vulnerabilities of an energy system unable to adapt to the 21st century climate. While the authorities blamed the turbines, millions of people froze without heating, hospitals worked with emergency generators, and citizens (such as state deputy Brandon Woodard, in Kansas) they wondered if those interruptions would become A new standard. If you want also, the event left a teaching: reliability does not depend on a type of energy source, but on an integrated, resistant and modernized system that combines technologies, storage, interconnections and preparation against climatic extremes that will be more frequent. In Texas, loading the blame for the wind was a convenient, but dangerous distraction. As almost always, the true enemy were not renewable, but negligence.
