How to do it and what time limit do you have?

by

Let’s tell you how you can check the operation of your new V16 beacon without alerting the DGT. As you know, these beacons have an internal SIM card that connects with the DGT, so that when you activate them because you have an accident or breakdown, they can geolocate you. But what happens when you just want to check that everything works well on a beacon you just bought? Well, we are going to tell you the amount of time you have before this connection is established. Because in the end, when you have spent money on one, what you want is to see that it works to see if you should return it or keep it. 100 seconds margin As specified by the DGT in one of his postsV16 beacons and their SIM cards They have a margin of 100 seconds during which no information is sent. This is the time the device has to establish the connection with the mobile network, check its GPS and prepare to send data. This serves to provide a secure testing window, as well as to prevent false alerts or messages from being sent in error. This means that you can turn on the beacon and test that it works, since will not alert the DGT until 100 seconds have passed. This way, you can see that your light is working and everything is fine. Remember that you must activate these beacons on the roof of the car if you have an incident. And when they send your position to the DGT after those 100 seconds, it will be able to use the road information panels to warn other drivers, send notices to compatible navigation applications such as Google Maps, and make it easier to locate you. They are mandatory from January 1, 2026. In Xataka Basics | What to look for in a V16 beacon: requirements and how to check if the one you have or want to buy works for you

A Japanese city has had enough of its neighbors spending the day on their cell phones. So he has set a limit: two hours

by

“When you get on a train in Japan, most passengers are looking at their phones. They don’t do anything else.” Speaks Masafumi Kouiki, mayor Toyoake (Japan) and probably the country’s most recognizable face in the fight against addiction to smartphonesthe sleep hygiene and life away from the screens. The reason is very simple: despite the suspicion on the part of his neighbors, Kouiki has promoted an ordinance that limits the use of cell phones and tablets to two hours a day. The measure was launched October 1 and for now it has served one of the objectives that Kouiki pursued: to move consciences and generate debate. What has happened? That October has arrived with a curious legislative novelty in Toyoakea city of almost 70,000 inhabitants in Aichi Prefecture that in practice functions as a dormitory city for Nagoya. On Wednesday the 1st, a new rule came into force that restricts the time that your neighbors can spend in front of a screen for recreational reasons: maximum two hours. 120 minutes. Not one more. The measure was announced months ago, in Augustwhen it was still a proposal, and despite the huge stir that it generated has managed to move forward: in September it received the endorsement of the municipal assembly with 12 votes in favor and seven against. What does the standard say exactly? Roughly speaking, the ordinance, 2,400 charactersestablishes a limit on the recreational use of smartphones, tablets, consoles and computers. The rule applies to Toyoake residents and sets that limit at two hours a day, not counting time spent studying or working. There is an important nuance, of course: although it is an ordinance endorsed by the municipal assembly, in reality what it offers is a guidelinenot a mandatory rule. No one will check whether the residents of Toyoake conform to that standard or not. No sanctions are foreseen either. This is just a recommendation. Is it wet paper then? At all. To begin with, because Japanese culture exerts strong social pressure to follow official guidelines. Beyond its real impact, the rule has also served to open the debate on the excessive use of screens and its influence on aspects such as sleep. In fact, the same ordinance advises that younger children stop using their devices at 9:00 p.m. and those in secondary school and those under 18 should not drive them after 10:00 p.m. The objective: guarantee your correct rest. That’s all? No. On October 1, coinciding with the entry into force of the rule, the Toyoake Government sent emails to young people and parents in the city to insist on the same message. Primary and secondary school students were in fact urged to “take care of their rest and health hours” and agree with their families how much time they would dedicate to their devices. “The main objective of the ordinance is to guarantee sufficient hours of sleep,” underlines the organism. The City Council has also carried out a survey among 250 residents registered in its monitoring system and wants to find out the real scope of the guideline: whether the use of smartphones during free time, the duration of sleep or the hours of family conversation changes. TO beginning of next yearIn fact, the authorities want to do a new survey among their students. Why have they done it? To change habits. “It’s very sad to end the day looking at your phone all the time at home,” explained a few days ago Kouki a The New York Times. “I hope citizens change their behavior.” Rather than strictly limiting the recreational use of screens to 120 minutes a day, its purpose is to invite “reflection and debate” and make people think about how much time they spend on screens and until what time they do it. In 2024, a state study revealed that, on average, younger Japanese (those in primary or secondary school) invest about five hours up to date on their mobile phones. And not only that. More than 80% of Japanese people between 15 and 24 years old consider themselves “dependent” on smartphones and 14% already show symptoms of addiction. How have people responded? Depends. Not everyone has reacted equally well to Kouki’s attempts to restrict screen use. Although it is not a mandatory rule nor are there fines for breaking it, there are those who believe that the mere existence of the ordinance means an intrusion in the lives of the people of Toyoake.”In one sentence: it’s none of your business”, claims Mariko Fujie, one of the local politicians who voted against. In his opinion, there is no “scientific evidence” to support a norm that, he warns, also does not take into account the perspective of young people. “Many of my supporters find it condescending. This ordinance is complete nonsense.” Is Toyoake a unique case? Yes. And no. The Town Hall assures that theirs is the first standard of its kind in Japan. This is also presented by media such as The Japan Times either The Mainichiwhich have highlighted its pioneering nature. Whether or not this is the case, the truth is that it is not the first attempt by a Japanese public institution to put limits on the use of screens among the population. Especially among young people. A few years ago Kagawa promoted another ordinance that aimed to restrict young people’s access to video games. Their objective: that minors do not dedicate themselves to them more than one hour daily during the week, a margin that the authorities were willing to extend to 90 minutes on holidays. In Yamato, another town, they also prohibited use mobile to pedestrians while they walk.

Walmart has already approved the first green hydrogen truck in Latin America. Its great limit: the load infrastructure

by

What if the future of heavy logistics in Latin America had already begun, and would have done it with a single truck? In a region where the transport of goods depends largely on diesel engines, Walmart has achieved homologation of the First Tonnage Tonnage Moved by Green Hydrogen. It happens in Chile, with a vehicle that, on paper, It can exceed 700 km of operation without issuing CO2. It is a test, for the moment. But one that marks the beginning of something much bigger. Chile has not only been the country chosen to test this truck: it has also been the engine of a public-private collaboration that seeks to open the way in heavy transport without emissions. Walmart participates in the Hidrohaul program, promoted by the Corporation for Production Promotion (Corfo), with an initial investment of 6.15 million dollars and a clear goal: Check if this technology can climb. An experiment that can mark a before and after For Walmart, the experiment fits with Its global objective to decarbonize all its logistics operation before 2040. For Chile, it is a general essay of what could become a National Transportation Network Green hydrogen driven. Manufactured by the Chinese company Feichi Technologythe truck uses a hydrogen fuel battery that generates the electricity that feeds its engine. Can transport up to 49 tons and is designed to travel up to 750 km per full load with 75 kg of hydrogen. Although it does not seem, this truck is also an electric vehicle. The difference is how that electricity generates. Instead of loading a battery connecting to the network, use a Hydrogen fuel battery: A system that mixes hydrogen with oxygen to produce electricity, water and heat. That electricity feeds an electric motor that drives the truck. There is no combustion, there is no CO2. And as a byproduct, it only emits water vapor. It is a different way to reach the same destination: a heavy transport without emissions. It all starts in Quilicurain the metropolitan area of Santiago. There, Walmart Chile installed in 2023 The first green hydrogen industrial plant in the countryin collaboration with Engie. The installation has a 0.6 MW electrolyzer which uses electricity from renewable sources – solar and wind – to separate water molecules and generate hydrogen. That plant not only supplies the new truck: it also feeds a fleet of hydrogen lifting wheelbarrows that already operate in the logistics center. The refueling, the great challenge for this to climb The autonomy of the truck is sufficient to operate within the central area of the country, but not beyond. Today there is no public network of trucks for trucks. The challenge is not only technical, but also logistical and economic: how many trucks will need to justify a hydroiner? ¿Where to place them To cover routes without wasting resources? In scenarios like Californiathe order of dozens of high volume stations is projected to serve several thousand trucks towards the beginning of the next decade. Chile will have to solve its own puzzle. The big question is not whether hydrogen works, but it is worth betting on it. In long -running trucks, it has clear advantages: autonomy, quick recharges, zero emissions and lower impact of weight than in pure electric. But it is still a expensive technology, with a limited refueling network and a lower energy efficiency compared to other options. It is not a universal solution, but a useful tool on the right place. That is precisely what Chile is trying to find out: if the hydrogen fits on its real logistics map.

The industrial paradox that has put worldwide trade to the limit

by

In Europe, steel costs less than a bottle of water. In the United States, it costs almost double if it comes from abroad. And in China, it produces so much that the world no longer knows what to do with it. According to estimates by the Organization for Economic Cooperation and Development (OECD), The excess world capacity will reach 721 million tons within two years. And no one is willing to stop. Steel that is left over. The steel industry lives a perfect storm: global overproduction, state subsidies, fall in internal demand in China and protectionist policies. In a report for the New York Times They have explained it through the Tata Steel plant in Ijmuiden (Netherlands), one of the most advanced in Europe. It manufactures steel on commission for high precision applications. Even so, the company announced 1,600 layoffs this spring, while 18,000 jobs were cut throughout the European Union and nine million tons of capacity were closed in 2024. The background reason, As explained by the same mediumis the avalanche of cheap steel from China, which manufactures more than the rest of the combined world. This overproduction, fueled by government support and lower environmental standards, has flooded global markets, forcing traditionally non -exporting countries such as South Korea and Japan to seek buyers desperately. A scale problem. Steel is much more than an industrial product. As He remembered for the New York environment Atlantic Council researcher Elisabeth Braw, steel is one of the few goods that every country wishes to have “in any circumstance.” Its use ranges from food cans and forks to war tanks and combat planes. However, there is another aspect to take into account: steel pollutes. As We have already explained in Xatakaeach ton produced emits two tons of CO₂, which is equivalent to 7% of global emissions. This makes steel an obstacle to achieving climatic objectives. The paradox is clear: the world needs less steel, but nobody wants to be the first to close ovens. The industry is too big to abandon it, but too inefficient to sustain it as it is. This generates a vicious circle between price drop, minimum margins, lack of investment in clean technologies and greater pollution. The King of Steel. China is not only the largest world producer of steel, but also exerts a disproportionate influence on the global market. It produces more than the rest of the combined planet, largely thanks to a more lax state and environmental regulations system than in the West. According to data from the National Statistics Office cited by BloombergChinese production registered in June the greatest fall in ten months, due to adjustments in the capacity and government pressure to contain internal competition. Even so, more than 60 % of Chinese gatherings are already profitable, a notable leap compared to 30 % of just a year ago, driven by the rebound in demand in sectors such as automotive, machinery and, above all, exports. These exports have continued to grow despite international tariffs and commercial tensions, flooding markets in Europe, Asia and Africa with steel at dumping prices. This dynamic has reduced the margins of Western steel and left them without sufficient resources to invest in low carbon technologies, a problem that the OECD considers a critical obstacle to achieve the climatic objectives. With an still weak internal consumption for the real estate crisis, Beijing seems to bet more and more to export its excess steel as an economic influence tool, which multiplies clashes with the United States and Europe. Another power wants to face. The United States also wants to regain control of its industry. In January 2025, then President Joe Biden blocked the purchase of Us Steel by the Japanese Nippon Steel, claiming national security motifs. The decision, backed even by Donald Trump and by the unions in the sector, generated diplomatic discomfort in Tokyo and tensed the relationship with one of its main strategic allies. Six months later, that same logic translates into terrain conversions. In an article for The Washington Post They have detailed as in Weircon (Western Virginia), a city forged by the steel, the company Form Energy has occupied part of the vacuum left by the closure of the local steelter, hiring more than 400 workers – many of them extrabajadores of the steel – to manufacture energy storage batteries. Although initially driven by federal subsidies, the initiative has even survived the cuts of the Trump administration, and represents an attempt to reindustrialize without fully renouncing the steel legacy. The message is clear: the United States does not want to let your steel, your industrial narrative, fall into foreign hands. And Europe is trapped. In all this triangle, Europe loses ground, trapped Between the Chinese dumping and Tariff hostility of his Atlantic ally. And now, in addition, committed to buying massive amounts of fossil fuels to avoid major sanctions. Being more concrete, Europe has some of the most advanced gaits in the world, such as the Tata Steel plant in Ijmuiden, the Netherlands, which manufactures specialized steel for batteries and high -end cars. However, he is facing a perfect storm: high energy costs, strict environmental standards, unfair competition and political pressure. Despite attempts to modernize – like Tata’s plan to go to hydrogen – the necessary investment is counted in billions. In addition, American tariffs have hindered European exports, just when block countries need income to finance ecological transition. As for the United Kingdom, the government has had to intervene high ovens and subsidize plants to avoid massive closures. And in Germany, European industrial bastion, the approaches face the largest decline in decades, with a 11.6 % drop in production during the first half of 2025, According to The New York Times. Where does steel go? The steel faces a crossroads: between the industrialization of the twentieth century and the ecological demands of the 21st century. The only sustainable output seems to be green steel. Companies such as Swedish SSAB have already begun to produce it through … Read more

If something matches all mortals, it is the limit of 100 ml in the plane’s hand luggage. That is about to end

by

100 milliliter boats in a transparent bag of up to a liter of capacity. That is the limit that everyone, absolutely everyone, we have tax if we want to wear liquids in hand luggage when traveling by plane. But that measure, dating from 2006, looks close to being eliminated in the European Union. The reason? The new 3D scanners That, little by little, community airports begin to populate. But let’s start at the beginning. Why 100 ml? To understand the why we have to go back to 2006. The 11-S attacks in 2001 caused, among other things, an important hardening in security measures Airport. With this tragic recent event, in 2006 the CIA and the MI5 frustrated an attempt of attack that sought to explode several aircraft in full flight using two hidden liquid explosives in bottles: acetone peroxide and hexamethylendiamine triperoxide. From then on, the authorities decided to limit the maximum capacity of the boats to 100 milliliters. The figure is not trivial. According to explained Kip Hawley, former director of the TSA (Transportation Security Administration), some explosives need to have “a critical diameter to achieve an explosion that causes damage.” The container size is, therefore, a self -safety measure itself as conventional X -ray escapes They cannot detect Liquid explosives reliably. Image | Roberto Arias Yes, an attacker could devote himself to mixing the liquid of several small bottles in a larger in full flight, but the liquid explosives are very unstable, so mixing them on board can end quite badly for the attacker. Acetone peroxide explosions They are 80% more powerful than those of the TNTbut it is a much more complicated compound to manipulate, to the point that a stronger blow of the account can cause an explosion. The new scanners. The arrival of C3 scanners, however, has the potential to change the rules of the game. These scanners use computerized tomography to generate three -dimensional luggage images, so that the operator can see the content without the passenger to open the suitcase or backpack. Yes, but no. These scanners have gone, little by little, reaching European airports. In fact, until September 2024, some airports allowed to pass security control with liquids above more than 100 ml. However, last year the European Union activated a temporary restriction due to a technical problem in the scanners. First in the HI-SCAN 6040 CTIX and, finally, in all others. That is why right now, even if you go through a new scanner, liquids are still limited to the capacity that accompanies us since 2006. Out limits, but calm. As reported from Brussels, the European Union intends to eliminate this limit as soon as possible. Only the approval of the European Civil Aviation Conference (CEAC) is missing, according to the Italian newspaper Corriereit could come as soon as today or Monday. Now, the reality is what is: there are few airports that have these scanners. According to him Airports Council International Europeas of July 2024 there were only around 350 scanners in 13 countries. What does that mean? That the measure will not be removed from all airports. “It will only affect those airports that currently have this state -of -the -art team of scanners,” they point out from the commission. When will it happen? How before and imminently, they expect from Europe, although there is no concrete date.

The strokes have become a huge silent health problem in Spain. And there are ways to limit risks

by

Every year 90,000 cases of strokes are produced in Spain that leave 23,000 deaths on average, According to the data of the Spanish Society of Neurology. This number could be significantly reduced, after all, many of the Risk factors which are associated with this type of event correspond to behaviors and habits that we can modify. Before reviewing what the risk factors are controllable or not, associated with the stroke, maybe it is appropriate to consider us What exactly is an stroke. The stroke or stroke (stroke) occurs when the blood flow that reaches a part of the brain is interrupted or drastically reduced. There are two types of accidents: ischemic and hemorrhagic. The former are the most common, are produced by the blockade of one of some circulatory route, for example by a clot or its narrowing as a result of fatty deposits. Hemorrhagic strokes for their part are produced by the breakage of a blood vessel. There is no exact list of risk factors that are related to these episodes since there are numerous overwhelms and interconnections Among these factors. Nor can we make an accurate distinction between the factors that we can control and those that do not. A clear example is that of diabetes. This disease is a risk factor in the appearance of ICUTS. Suffering or not this disease is not under our control, but we can avoid factors that in turn are linked to it. Despite the difficulties when delimiting these concepts, experts estimate that controllable risk factors are associated with 60% and 90% of the risk of suffering a stroke. That is, avoiding these factors we can reduce very significantly the risk that this type of event will be triggered in our brain. And what are the risk factors on which we have the greatest control? According to the National Heart, Lung and Blood Institute From the United States, controllable risk factors include blood pressure, obesity, physical inactivity, poor diet and tobacco. According to the American medical institution Johns Hopkins Medicinea blood pressure of 140/90 or higher is a factor that can condition our probability of suffering such an accident. Obesity, food and physical inactivity They are clearly interconnected risk factors. Smoking is one of the Risk factors More widely mentioned, but alcohol and some recreational drugs such as intravenous or cocaine are also related to an increase in the risk of suffering from an stroke. Some legal substances such as the contraceptive pill have also been related to an increased risk of stroke. With anxiety, depression and stress, something similar occurs than with other diseases: we have a certain degree of control, but this can be very limited depending on the circumstances of each person. Something similar happens with the environment in which we live: although residing or working in contaminated areas can aggravate our risk of suffering from an stroke, changing work or residence is often not in our hand. What we cannot change Some of the risk factors that we associate with the stroke totally escape from our control. Maybe age is the most important: Age. As we become greater the possibilities of suffering a stroke are increasing. Sex is another factor linked to the appearance of this disease and in a unique way: it is fine at an early age men suffer from these accidents more frequently, the greatest life expectancy of women means that throughout life these suffer more such problems. Different ethnic backgrounds can lead to different levels of risk: in the United States African -American, native and Hispanic people have a higher risk of suffering a stroke. Finally, Genetics And family history can also be considered risk factors, especially in cases where a family member has experienced one of these events at earlier ages. In addition to the risk factors, it is worth remembering what are the main symptoms that accompany these events in order to better identify an stroke and improve the chances that whoever suffers it receives medical assistance on time. There are a few key factors that can help us Identify an stroke quicklybut there is also a challenge of symptoms that can also be associated with strokes. Among the Key symptoms There are the loss of strength or sensitivity in the face, arm or leg, which usually swams to a single side of the body; Confusion in speech, for example in the use of unconnected words; sudden loss of vision; dizziness, loss of balance or the appearance of a severe headache without a clear origin.

Xàbia set a capacity limit and access control in its two most famous coves. The problem is that nobody wants to take care of it

by

In Xàbia they live around 30,000 people. At least according to the INE data, which only formally registered neighbors in the town. If we talk about the summer months and include visitors in the equation, the thing changes and that figure It multiplies exponentially. And it is understandable. Xábia is known for its landscapes, its gastronomy and beaches and coves as portitxol or grenadella. The problem is that this attractive threatens to be a collapse condemnation. One that this year promises Leave images of access to saturated sand. The beaches, face and cross. Having a beach near home in summer is a blessing. And an ordeal. Almost a year ago the residents of O Hío, in Cangas, a town in the Baixas Rías very popular for their sand, protest tourist that suffers every summer. To make clear their position on a Sunday they began to cross a village zebra crossing for minutes and minutes, blocking the traffic of access to the beach area. “The neighbors have the right to live. It is an avalanche of cars that not only contaminates, but affects everyone’s life because they park where they want,” regretted A neighbor. The Baixas Rías are not the only ones who deal with tourists in search of paradisiacal beaches. At the other end of the Peninsula, in Xàbia, the coves also attract thousands of vacationers, many of them aboard cars, which has forced the town to take action To control your transfer. Objective: Ordered beaches. Does Just a year The Alicante municipality presented a special device to control access to two of its most popular coves, the GRANADELLA and the Portitxolwith vigilantes in charge of supervising the passage and a regulated parking system in the street. The idea was simple: from June 1 to 21 (the “middle season”) the accesses were controlled only on weekends; From 21 that supervision became daily until September 13 and then the surveillance focused again on Saturdays and Sundays until October. It was not the only measure. Alicante Plaza Precise That in June 2024 the parking lot in PICT Tort began to be regulated, in the Cala Granadella, and La Barraca (Cala Portitxol). To avoid vehicle collapse, the City Council He chose to resort to a system with “barriers and payment”, which allowed visitors to park for almost all day (from 9 a.m. to 7:00 p.m.) paying nine euros for each vehicle. Once the parking lot was filled, the operators blocked access with barriers. “Avoid bottling”. And even City Hall He installed panels Informative on access roads to the coves so that drivers could know almost in real time the availability of parking spaces in Granadella and Portitxol. “The system tries to prevent the bathers from reaching the point where the control barrier is located and the parking lot is around,” I clarified The councilor of beaches. The idea was that these bathers could “opt for another beach and avoid bottling.” And arrived (almost) the summer of 2025. At the doors of 2025 Xàbia now meets a challenge, according to He revealed yesterday Levante-El Mercantil Valenciano. The newspaper ensures that the contest launched by the local government to take care of the control of access to Granadella and Portitxol seems to have not aroused the interest of any company. Last Monday the envelopes of the candidates opened and the executive discovered that no company had been presented. The exploitation of the service would not even attract the firm that assumed it in recent years. At the end of May Levant He already warned that Xàbia was approaching summer with the beaches without beaconing, anchoring buoys or supervision of access to the beaches. The tender of the surveillance, control and safety service in the coves of the town, which among other things aims to avoid the collapse of cars in Granadella and the Portitxol, would have been launched for a extendable year and a budget of almost 104,000 euros. Now, Clarify the newspaperthat hired has been deserted, the file has been filed and the coves face an uncertain horizon. “There are those who threaten to run over us”. The alleged disinterest in companies comes after drivers will alert last year of the encounters that live in the coves with choleric visitors. One of them admitted in August 2024 to Levante-El Mercantil Having met bathers who, when they find out that they cannot park in the area, take them with the workers, those who threaten or even love to run over. Without barriers or control, parking on the roads to Granadalla and the barrack also suppose a problem. When parking where they should not, cars complicate traffic and even reach hinder the step of firefighters and ambulances. In fact the sands already They have left saturation scenes.

more expensive light and marketers to the limit

by

It has been a month since the great blackout that left the entire Iberian Peninsula. Since then, the national electrical system has been operating under a new extreme surveillance protocol: “reinforced operation.” Its goal is simple, but ambitious: avoid another total collapse. Its effect, however, begins to feel in the pocket of companies, marketers and consumers. Reinforced operation? Electricity and the Government have chosen to contain renewables and activate backup technologies such as gas, hydraulics or nuclear to gain stability. These sources, although more predictable, are also more expensive. But this operational turn has a price: renewable energy is being left out, cheaper, in favor of more expensive conventional technologies. As He has collected Five days, this new strategy has triggered the participation of traditional plants in the so -called adjustment markets or technical restrictions. So is there a contradiction? After the blackout, many pointed to the low inertia of the system, associated with the high penetration of renewables, such as the great culprit. However, like has collected this medium In an analysis by Matías Zavia, the peninsular electrical system counted in the moments before collapse with an “according to European recommendations” levels: 2.3 seconds, above the minimum threshold of 2. Both Minister Sara Aagesen and Secretary of State Joan Groizard have confirmed this data in parliamentary headquarters. The technical explanation that gains force points to a chain of failures: anomalous oscillations, Almost simultaneous generation surgeons and disconnections. It was at that critical moment, with the peninsula already isolated from France, when the low inertia aggravated the final fall. It was not the cause, but the collapse accelerator. In the absence of the official report, planned for the coming months, the blackout is emerging as a complex structural failure, not as a simple excess photovoltaic. The real problem: a shooting price. Since this reinforced operation was activated, the costs of the electrical system have shot. According to El Confidencialthe so -called restrictions techniques and Adjustment services – requirements necessary to maintain the stability of the network – have been remarkable. The problem is that these costs are initially assumed by marketers, especially the smallest and independent, which do not have their own generation capacity and have to buy this energy in markets managed by Red Electric. According to data the Independent Energy Marketers Association (ACIE), collected by the confidentialthe average cost of technical restrictions has gone from € 11/MWh in April to € 24/MWh in May, and at specific times it exceeds € 30. This pressure has led to several marketers, such as totalenergies, Moeve or Factorenergy, to send a letter to Red Eléctrica requesting clarity and a temporary forecast of these extraordinary measures. It has already been seen in the light bill. Starting with the almost 10 million consumers host of the regulated rate (PVPC) that have seen how their receipt At least four euros rose in May. And what began as an extra cost for companies, also begins to move to private clients and companies of the free market. In B2B contracts, some marketers have begun to introduce an “antiapagon rate”. As it picks up fiftiesthe client assumes up to € 12/MWh in adjustment costs, and what exceeds that figure is impact at the end of the month. In the case of households, where contracts cannot be modified easily, companies choose to raise the price of the megavatio in renewals or new offers. The dilemma is clear: raise prices or assume losses. A market to the limit. Independent marketers denounce that Red Electrica has increased costs without offering clarity on how they are calculated or until when they will be maintained. This uncertainty prevents planning and leaves those who do not have financial muscle to cover this volatility, According to El Confidencial. The pressure of the sector has also reached the institutional level. Acie, which brings together 20% of the market, has sent formal letters to Red Eléctrica and the Ministry for Ecological Transition asking for explanations and collaboration, such as He explained Fifodies. To date, they have not received a response, which increases the tension between the operators of the system and the most vulnerable actors in the electricity market. With an ignition system … The risk is not only a more expensive invoice, but a more concentrated and less competitive market. If independent marketers continue to carry costs without certainty or regulatory support, many will not survive. And if they disappear, consumers will have fewer options, more dependence on large electricity and less power to negotiate prices. The reinforced operation maintains the system on, yes. But it can also be extinguishing an essential part of the market: its diversity. With the technical report even on the horizon, what happens in the coming months will mark not only the stability of the network, but also who can continue to compete in it.

It is very useful for us to always carry it with us, either on the mobile, on the PC or on the device we want, since there is no device limit. In addition, it also stands out for being very simple to use, so you do not expect a complex interface. On the contrary. It is also worth noting that Surfshark VPN is included in the Starter Plan. This comes with an additional tool included ALTERNATIVE IDideal if we do not like to enter personal information on certain web pages. Thanks to this tool, we can create virtual data that we can use where we want. This plan, as we have said a little higher, has a price of 2.19 euros a month. That means that we can have two years of the service complete for a total price of 55.56 euros, a discount if we take into account that the price that this period of time is normal is 439 euros. And there does not end the thing: We will have 3 months extra giftso we will enjoy 27 months in total. Some of the links of this article are affiliated and can report a benefit to Xataka.

Its solar panel in tandem already exceeds the theoretical limit of silicon

by

The efficiency of solar panels always andStá in object of studyand the only country capable of developing new advances is China. In fact, the company Longi has achieved have even a certificate of the National Renewable Energy Laboratory (NREL) of the United States. Short. The Chinese giant of the solar modules He has achieved A new record in solar energy conversion, reaching 34.85% efficiency in a pervskita solar cell in two terminal tandem. In this way, Longi has managed to overcome The previous 34.6% record that Longi herself held two years ago. A key technical advance. To understand the feat, it is important to know the tandem design. This structure combines an upper cape of Perovskita and a lower crystalline silicon, allowing to capture different ranges of the solar spectrum. Through a technique called bilayer interface passive, two layers are introduced that improve the passage of electricity between both active layers. On the one hand, lithium fluoride (LIF) acts as a barrier against load losses. On the other, the ethylendiamium diyoduro (EDAI) fills the nanometric scale holes, ensuring a more efficient load extraction. It’s not just about materials. The Chinese company has also redesigned the structure of the crystalline silicon, making the frontal surface more rough to facilitate the adhesion of the Perovskita and maintaining a standard texture in the rear to optimize the capture of infrared light. This texturing improves the absorption of light and, therefore, the efficiency of the panel. Achievement is not less. Apart from overcoming its own record, the Chinese company has overcome The so-called Shockley-Queisser limit. In other words, it has managed to exceed the maximum efficiency limit marked by 33.7% for a single union. However, tandem cells, which combine different materials such as Perovskita and silicon, can overcome this limit by taking advantage of a broader range of the solar spectrum from the theoretical aspect. For example, research has shown that tandem cells can achieve higher efficiencies 40%and theoretically, some configurations could reach up to 60% . Institutional support. Thanks to the participation of the universities project such as Suzhou and Hong Kong (HKPU), together with the Huaneng Clean Energy Research Institute, They have allowed A Longi perfects its silicon hetero -union technology and optimizing manufacturing processes, bringing Tandem technology to a more commercializable level. The next challenge. Longi has shown that the solar efficiency roof remains a mobile objective. However, he will now have this laboratory technology to the mass market. The durability of tandem cells, production costs and industrial scalability They will be key factors To determine if this record becomes a commercial standard or another technical advance without immediate practical application.
