A study has simulated what would happen on Earth if Asteroid Bennu ends up impacting in 2182. The climate we know would not exist

by

The chances of crashing an asteroid of “large” category on our planet They are, on average, 0.001%. Therefore, everything that begins to raise that figure begins to be “less” normal. Hence Let’s talk about 2024 YR4 and its 1.6%. That said, and although there are less possibilities that it will occur, due to its size, The Bennu Asteroid It would be one of the most dangerous of the solar system. How much? That is precisely what they wanted to find out in South Korea. Potentially dangerous. The Bennu Asteroid, an object close to the land of approximately 0.5 kilometers in diameter, has been identified as one of the greatest known space threats. His orbit brings him closer to our planet every six years, and although the risk of impact is extremely low (right now it is 0.037%), the possibility of colliding with the Earth on September 24, 2182 has led the scientific community to the scientific community analyze in depth its possible effects. An unprecedented recent study, Posted in Science Advances By researchers at the IBS Institute of Climate Physics of the National University of Pusan ​​in South Korea, it has modeled for the first time the climatic and ecological consequences of an impact of a medium -sized asteroid such as Bennu. The results, of course, are not the best. The legacy of an ancient asteroid. Scientists believe that Bennu detached himself from a larger asteroid, rich in carbon, between 700 million and two billion years ago, progressively approaching the Earth’s orbit. Its composition is of great scientific interest for a simple and fascinating reason: contains key elements for lifewhat motivated NASA’s Osiris-Rex mission to explore it in 2020 and bring samples to Earth in 2023. However, and beyond its scientific value, Bennu represents a real risk that, although unlikely, cannot be ignored. Impact simulation. As explained in the study, South Korean researchers designed Detailed models to analyze how that possible impact of Bennu would affect climate, biodiversity and food security. What did they find? The most extreme scenario revealed that the impact would inject into the atmosphere between 100 and 400 million tons of dust. In other words, more graphic: it would block sunlight and plunge the planet in abrupt cooling. As for the effects, the simulation showed a certainty: They would be global and devastating. Namely: reduction in the average planet temperature in up to 4 ° C, a decrease comparable to the eras glaciers, 15% drop in rainfall, affecting the water supply and agriculture, loss of 32% of the ozone layer , exposing life on Earth to dangerous levels of ultraviolet radiation, and the decrease in photosynthesis by 20-30%, both in terrestrial and sailor ecosystems, which would cause a serious crisis in food production. In short, these combined effects would trigger, according to the study, A winter of impact that would last between three and four yearscausing global famine and an ecological crisis of enormous proportions. Comparison with past events. While a Bennu impact would be devastating, the truth is that the earth has faced major threats. The best known event occurred 66 million years ago, When an asteroid of 10 kilometers in diameter hit what is now Chicxulub, Mexicocausing the extinction of dinosaurs and climatic alterations that endured thousands of years. In comparison, Bennu is significantly smaller, but large enough to cause mass destruction and deeply alter the biosphere. Not just that. Other studies suggest that medium -sized asteroids such as bennu collide with the earth approximately every 100,000 to 200,000 years, indicating that Our prehistoric ancestors could have experienced similar events with impact on human evolution and global biodiversity. Impact on the oceans. Despite the catastrophic effects, Bennu’s impact could generate an unexpected reaction on the oceans. The iron released in the stratosphere would be deposited in the sea, stimulating the proliferation of phytoplankton and zooplanktonessential organisms for the marine food chain. According to the study, while land ecosystems would take two to three years to recover, Marine life could recover in just six monthsand even exceed their levels prior to the impact due to the increase in nutrients. Planetary Defense Strategies. Despite the low impact risk, NASA and other space agencies work on the development of planetary defense technologies. For example, the Dart mission (Double Asteroid Redirection Test)carried out in 2022, he successfully demonstrated the human ability to divert the trajectory of an asteroid, opening the door to future mitigation strategies. And besides Bennu, there are other more immediate threats. For example and as we have explained these days, Asteroid 2024 YR4 has a 1.6% probability of impacting the Earth in 2032which reinforces the need to continue with research and develop effective prevention systems. What does seem clear to this last study is that not only reveals the vulnerability of our planet to cosmic events, but also highlights that need to advance surveillance and planetary defense technology. While the possibility that Bennu or any other asteroid impact the earth is minimal, geological history demonstrates that events of this type have shaped the evolution of life and could happen again in the future.

Online trade was supposed to end the shopping centers. Reality has been just the opposite

by

The combination of online trade boom and the Platforms of Ecommerceadded to The misgivings that came from the US and THE MAZAZO The pandemic made the shopping centers face a particular (and threatening) ‘storm’. There was even talk of “Apocalypse of retail“. That is left behind. Or at least this is suggested by the figures that handle the commercial areas of Spain. In addition to grow in sales and activitythey have become an appetizing candy in the eyes of investors, one that moves hundreds of millions of euros in transactions. And there is a round data that demonstrates it: 1,000 million. Complicated years. Pandemia hit enough sectors and business models. And shopping centers They were no exception. Between health restrictions and changes in consumption habits, during the worst years of COVID-19 its managers suffered a Influence collapse of customers and a collapse in Sales. As in other industries, although in the case of large surfaces that scenario was added to another more structural cariz threat: the competition of the Ecommerce and platforms such as Aliexpress. Was who wondered If the shopping centers would have a future in a world in which trade and entertainment changed driven by Amazon or Netflix. In the US they even coined the term “Apocalypse of retail“. From there a fear expanded that He arrived in Europe (and Spain) despite some experts They warned Already at that time that the sector was different here from the American, with an average density of commercial areas lower than that of the US market. From ugly duckling to swan. That scenario seems to be behind. The salmon press carry months suggesting itbut the most forceful test left it a few days ago A chronicle of Five days in which a significant fact is provided: 2025 has started with five operations of sale of shopping centers from Spain to the point of caramel and adding, together, around one billion euros. The data is interesting for its volume. But also because it shows that, despite the catastrophic scenario that was painted years ago, when there was talk of the “apocalypse of the retail“And the threat of electronic commerce, shopping centers continue to interest investors. As suggests The chronicle of Five days, The data suggests that the old “real estate duckling” will become swan. What operations are? These five operations on track and in which relevant news is expected during the first half of the year are starred in centers distributed by the country. The Economic newspaper speaks of Mediterranean space (Cartagena), Corridor Park (Torrejón de Ardoz), the 50% of the capital from Madrid Xanadú (Aroyomolinos), Bonaire (Aldaya) and Alcalá Magna (Alcalá de Henares). Each case has its peculiar, route and actors, but share a common denominator that says a lot from the sector: they all point to draft operations, for high amounts, nine digits. Its sum would in fact around the one billion. And the most curious thing is that the figure does not seem to respond to a specific interest in shopping centers. The AECC data They show that in 2024 there was already progress in relevant transfer and investments for more than 900 million. The key: profitability. It is not surprising that 2025 start with such a scenario. The operations of the shopping centers are moving investmentthe sector It has managed to grow both in billing and in traffic throughout the last year and appraisals – after the scenario that was lived in 2022 and 2023 – are attractive enough to awaken the appetite of investors. The economic return they aspire is also tempting. Five days Precisethat transactions are closing to a profitability between 7 and 8%, which exceeds other assets, such as offices Prime or the house for rent. “The commercial centers market is at an optimal time. Investors are aware that assets offer a ratio between very attractive risk and profitability and we are facing a window of limited opportunity to benefit from these conditions,” He pointed in 2024 Augusto Lobo, Capital Director Markets Retail de Jll Spain. “Again at the radar”. In July the financial firm BNP Paribas Real Estate launched A similar message When talking about Spain. “The shopping centers are again in the radar of investors,” he summed up in Your balance July after remembering that during “a long period” the activity in the sector retail He had focused on other types of premises, such as commercial miles (High Street) or food. The keys to change: good sales and influx figures and “profitability that begin to be attractive.” Throughout the last months they have been published Several balances that They reflectIn fact, shopping centers have thrown out of the sector retailagglutinating a good part of your investment. “In the years before the pandemic it seemed that the segment of physical stores was falling and that the Ecommerce I was going to monopolize the sector as a whole. However, it has been shown that the sector retailIt is very resilient and still has a lot to offer “, Cristina Macarrón commentsfrom Castilana Properties, to Five days. In 2025, with good mouth taste. The shopping centers have started 2025 with a good foot for another reason, beyond the millionaire transactions in the trees: despite the most pessimistic predictions of the “apocalypse of the retail“, In Spain, large surfaces are gaining traffic and billing, a trend that probably also influences investors’ prospects. The last Cushman & Wakefield data They show that sales on these surfaces grew 3.5% in 2024, an increase very similar to that registered in the influx of customers, which was 3.4%. Another positive percentage for the sector is the occupation of commercial spaces, which has reached 95.4% of the GLA, the gross alleged surface. They are good data, especially if one takes into account that in 2023 the sector (commercial centers and parks) had already raised its sales by 9.6% year -on -year, with 52,051 million eurosachieving its historical maximum.

The NFC takes its first big step in Spanish football. Atlético has adopted it to access its stadium

by

Atlético de Madrid has just become the first LaLiga club to implement technology NFC To access the stadium. It is good news that in turn uncovers the delay that this technology has had in Spanish football, who has opted much more for the codes QR as an alternative to entries and physical fertilizers. Why is it important. The NFC has been demonstrating more than a decade to be an efficient and safe system in payments and accesses, but Spanish football has remained anchored to the QRs, which have their advantages but slow down the process. The context. Asia or the United States normalized the NFC for a long time for all types of transactions, including access to enclosures and events. In Europe, and especially in Spain, we have maintained a certain resistance to adopt it. The NFC surpasses QR in three fundamental aspects: Speed: Transmission is immediate, without the need for focus or scan. Security: requires physical proximity and a biometric or PIN validation prior to the device. Reliability: It works in low luminosity conditions and does not depend on the brightness of the screen or the print quality. Between the lines. This Atletico movement tells us about the change in Spanish football mentality: technology is no longer just something to use in the field or in the locker room, nor a simple marketing tool: it is an element with which to improve the experience of the fan. The Atlético, in fact, is the first LaLiga club that has all the input and fertilizer formats: physical and digital card with QR, physical entrance or in PDF for mobile, and Wallet both of the fertilizer and the entrance.

Elon Musk is applying to the US the same recipe that has applied to all its companies

by

Elon Musk did not receive Not a single vote in the elections from the US, neither a dollar from the US government receives. However, many consider him the most powerful person in the country, and has declared war on bureaucracy. Not two weeks ago that Donald Trump was invested as 47th President of the United States, but Elon Musk has had plenty of time to put An army of twenty -year -old engineers Even the kitchen of the US administration. That a private citizen, without an official charge and without obligation to account for anyone, can access classified information has lit all alarms in the country. Elon Musk’s “demon” mode. The “modus operandi” that has shown Doge during its first weeks of operation carries the Elon Musk personal stamp. Just observe minimally what happened when Elon Musk He took Twitter controleliminating functions and dismissing your staff, to find the same pattern in the “control” of Donald Trump that He has executed Doge In the last two weeks. The Millionaire has used this system of harassment and demolition of the structure established in all its companies or projects. Your biographer defined This scenario as “demon mode”, in which Elon Musk orders to stop everything and eliminate all the unnecessary or superfluousregardless of whether some norms or regulations are breached in the process. As he quotes in his biography, Elon Musk considers these operations as “giving things to things and purging all the shit of the interior of the system.” Work in “Extremely Hardcore” mode. When Elon Musk enters that “demon mode” demands a Extreme work commitmentliterally describing it as “Extremely Hardcore”. Again, something we already saw in the landing of Musk on Twitter. Now, Doge’s team is also applying that extreme work discipline and has even mounted sleeping beds in the offices of the Blanca to the White House that became its headquarters, According to sources of The New York Times. As published by Musk, they are working Even weekends. The US is not a company. Elon Musk applied that optimization exercise in Space X when he developed his First Merlin engineswith the Starlink satellites and with the Starship rocket. Tesla also suffered Musk’s “demon mode” when he faced the company bankruptcy If the Production rhythm of your Model 3. Elon Musk even He slept under the table of his office while I found formulas To optimize the assembly line. The millionaire has applied these optimizations in all its companies using a policy of Challenge to regulationswhich left them exposed to sanctions. However, they are private companies and, as such, they must be aware of the risk of incurring these infractions and assuming the consequences. However, what Many wonder in the US It is whether the government of a country can afford that luxury. Doge and officials. One of Doge’s first battles has been against officials, which began when the president He repealed the measures that protected career officials, those who carry out their work in the administration regardless of who governs. Following the same pattern as on Twitter of 2022, it was sent An email more than two million officials under the matter “Fork in the Road” (bifurcation on the road). In that email, They were invited to give up just by responding to the mail in exchange for receiving the equivalent of your salary until September as compensation for dismissal. In 2022, mail trick It did not fullysince the company had to pay compensation to its ex -employed. In this case, it has not been too successful and the measure has been taken before the courts. Some twenty -year -old engineers. Another aspect of Doge’s “control” has been the Young entourage, twenty -year -old They had been doing practices In Elon Musk companies. These “black men” of Doge entered the databases More sensitive from the administration without even showing a government employee credential, since Doge is an external consulting body, not a government agency. In fact, in many cases they refuse reveal their names. To the officials who refused for a group of intruders They had access to the data that the Treasury Department has of millions of citizens, They were withdrawn from service. Treasury Secretary Scott Besent, He had to order To officials that allow access to the Musk team, since, remember, they are not government officials officially. Trump triggered. Doge’s “control” has raised controversy both for its intimidating methods and for the legality of its actions. The recent one Total closure From the United States Agency for International Development (USAID) by Doge has made alarms jump of those who consider that neither Doge nor Donald Trump have the power of Close government agencies. According to him Article 1 of the Constitution That is a prerogative that It must be given from the Congresssomething that has not occurred. Therefore, not only are they being questioned that “the black men” anonymous of Doge act in an opaque way by accessing the most sensitive databases of the government, but also put on the table if the own Trump would be overreach in their functions passing Above Congress’ competences. Citizen Musk. In the midst of all this storm: Elon Musk. A private citizen who does not pay accounts for his acts and only responds to the president, who has given him free way to access all areas of the federal government. Will it cut the funds of NASA, from the SEC or FAA with the same lightness that you have used with USAID? It is difficult to define where the public service of the millionaire actions begins and where its private interests. SPACE X receives huge amounts of NASA money and the increase in missions with the American space agency points to an upward trend in that financing route. In addition, Elon Musk has in his hand the survival of regulation agencies such as FAA that regulates precisely the spacex scope, so it becomes a judge and part, giving rise to a conflict of interest more than evident.

A VPN is ideal to protect us on social networks. Surfshark is one of the best and now it hardly costs like coffee

by

It is almost impossible to count the hours we spend on the Internet every day, especially with regard to social networks. It does not matter if it is Instagram, Facebook or Tiktok (for just mentioning some), most of us enjoy a lot of time immersing ourselves for them to hang out or share things with our acquaintances. Internet navigation or these networks, unfortunately, certain risks for our privacy or our information (especially when we use A public wifi network). Therefore, it’s not a bad idea to use A good VPNand although we have several free options that do not work badly, none of them yields as well as surfshark, One of the best options we have available. It’s nothing expensive, but now we have it at a very good price: only 2.19 euros a month. Surfshark Starter Subscription – Monthly * Some price may have changed from the last review Surfshark is the ideal solution to increase the security of our data It is not uncommon to seek information about today and see that there has been a new hacking. This is something that is the order of the dayeven in social networks, where there are few cases of users who suffer robberies of information through them (and in the most serious cases, the total theft of the account). With a VPN, we are winning an extra layer of privacy and safety, whether we use it from our mobile phone and from the PC. In that sense, use surfshark It allows us to maintain the privacy of our IP addresssince it prevents hackers or any entity from monitoring our activity on the Internet. In addition, when using a VPN in our usual use on social networks, we can also have another series of advantages. For example, Tiktok shows us content based on our geolocation, so using surfshark can allow us to discover What kind of videos are popular in other areas of the worldsomething suitable for creators. Eye, Because this plan brings much more withsuch as an advertisement blocker and emerging cookies windows, a generator of personal details and a masked email generator. And all this without counting that we do not have a limited number of devices in which to use surfshark. The usual price of surfshark VPN is 4.85 euros per month, so we would be paying more than 58 euros in a year. If we take advantage of the offer we have available right now, we will only pay 2.19 euros A month, so a full year would cost us just over 26 euros. And be careful because it also comes with three additional months of gift. Some of the links of this article are affiliated and can report a benefit to Xataka.

Google has announced he Gemini 2.0 launchtheir new family of AI models. They actually launched experimental versions of Gemini 2.0 Flash in December And above all they showed their preliminary reasoning model, Gemini 2.0 Flash Thinking, but now all those movements are consolidated with more mature and stable versions. Best of all, Gemini 2.0 Flash Thinking, OpenAi O1 or Deepseek R1is already available as one of the available models In Gemini’s mobile and desktop application. Gemini 2.0 is more “agetic”, and according to Google it can “interact with YouTube, Search and Google Maps.” The company announced these days bittersweet fiscal results: they have more money, users and benefits than ever, But they are on the defensive. SUCTAR PICHAI, CEO of Alphabet, highlighted how the company will invest 75,000 million dollars in AI for 2025, when its CAPEX (capital expenses) in 2023 was 32,300. The decision shows that clear intention to invest but not necessarily to lead, but to try not to be left in front of a competition that also seems willing to spend colossal amounts of money. One of the outstanding notes of this Google announcement is the launch of a Experimental version of Gemini 2.0 Pro. This model, successor of Gemini 1.5 Pro, is more precise and “factual”, and according to Google exceeds clearly to the previous version in programming tasks and mathematics related. Google qualifies Gemini 2.0 pro as “your most capable model so far”, and will be available for GEMINI Advanced subscribers and for those with access to VERTEX AI and AI STUDIO. Together with Gemini 2.0 Pro is Gemini 2.0 Flash-Lite, a lighter version that offers more quality in its response than the previous Gemini 1.5 Flash, but that maintains its speed and cost. This model has a gigantic context window (One million tokens) and multimodal support, and for example you can generate a brief description of a line for a set of 40,000 different photos … and all for less than a dollar, indicate those responsible.

It seemed that iOS was unwavering. Until this malware slipped in App Store and started reading screenshots

by

Talk about iOS (usually) to be synonymous with Talk about security. But there is no infallible operating system. In the case of Android, we are quite accustomed to the fact that occasionally Some type of malware in Play Storebut in Apple’s application store this is not common. For the first time, a malware capable of reading screenshots has been found in App Store. Is, According to Kasperskythe first case detected of an app published in APP Store capable of using technology to extract image text using Google technology. The Antivirus company has explained that this malware is part of a campaign that sought to attack users to find cryptographic keys. The severity of the matter comes from the distribution method: applications infected with both iOS and Android. In the case of Android, these apps exceeded 240,000 downloads. These apps were varied and did not follow a thematic pattern. Some were “Chat AI”, other Delivery apps, others of messaging … Some of these applications had thousands of downloads in the Apple application store. What was its operation? In both cases, the same. Apps executed technology OCR of Googlea Google Cloud solution capable of recognizing text automatically. Once we gave apps gallery permits, they were able to look for text in our images and send it to the server. Thus, the attackers were made with cryptocurrency wallet passwords or with phrases and recovery codes of any app. From Kaspersky they affirm that “they cannot confirm with certainty that the infection has been the result of an attack on the supply chain or a deliberate action of developers.” Similarly, they point out that there may still be apps with this malware available in application stores. As we always indicate from Xataka, it is crucial not to give gallery permits to apps in which we do not trust 100%.

The tariffs and doctrine “of Minimis”

by

On February 1, President Donald Trump issued a new Executive order in which he imposed 10% tariffs on all types of Chinese merchandise. That has ended up having an immediate impact on the business of Temu and Shein, two of the great Chinese electronic commerce platforms, and in the last hours a singular situation has been experienced. Duty. The activation of the 10% rate on Chinese goods that arrive in the United States is one of the measures that Trump has created for increase taxes to the countries with which it is most traded. In fact, he raised 25% tariffs for Canada and Mexicoalthough it has postponed its application for 30 days. No Chinese packages. The impact can be huge, and the first side effects have already been noticed. A few hours ago the US postal service stopped accepting packages from China and Hong Kong, which among other things caused all chaos between the Truck carriers They tried to carry their packages as they had done until then. Private courier companies such as UPS or Fedex did not announce restrictions at that time, indicate In The Verge. Restored service. As they point out In CNBCthe postal service ended up accepting those packages. In a statement On their website they indicated that both they and the customs service were “collaborating closely to implement an effective mechanism for collection of new tariffs to China, in order to guarantee the least possible interruption of the delivery of packages.” The exception “of Minimis”. China’s trade with the United States has benefited for years of an exception called “Minimis”, a Latin term that indicated that packages with value below $ 800 could enter the United States without paying taxes. It is a mechanism that platforms such as Shein or Temu have taken the opportunity to offer really competitive prices in their merchandise. They are not the only ones who have taken advantage of that “shortcut”, and also US companies such as Amazon, Etsy or Ebay have benefited from this exception. Trump puts an end to minimis. But this exception, which carries about a century Active, was blocked by the new president of the United States. The impact of this measure can be enormous: the American customs agency Indian Recently that it processed more than 1.3 billion minimis shipments in 2024. Not only that: A report The US government revealed that Temu and Shein are “probably responsible” for more than 30 % of all minimis shipments that arrive in the US, and practically half of all shipments of this type that do not pay taxes came from China. The rise of electronic commerce and the avalanche of arrival of low value products made the limit of minimis products in 2016 rose from 200 to $ 800 With the Obama government. To check all packages. The deactivation of the Minimis doctrine will cause the workload for messaging companies and postal service to increase colossally. In theory they must check all packages to verify that new regulations do not breach, something that could significantly delay (at least, initially) shipping times. Can Temu and Shein continue competing? Both platforms benefited from Minimis and the absence of current tariffs to be able to sell their products at prices with which it was very difficult to compete. Amazon began a plan to do that precisely with the launch of Amazon Haul: All at less than $ 20although shipments are completed in a weeks. Trump’s measures could make Amazon change their plans with that service. Most likely: that everything costs more. All these tariffs and taxes probably end up being paid by American consumers, for whom all products will probably be more expensive. As they explained In The Vergetariff rates “are a tax on the person or entity that imports goods, not to their exporter. A study of the National Bureau of Economic Research of October 2024 made it clear that American citizens with more tight economies will be the most affected. Spain and the VAT package. The situation that is now lived with Minimis’s doctrine remembers what happened in Spain in 2021. It was then that the call was activated “Electronic Commerce VAT Package“That made VAT apply to shipments with a value not exceeding 150 euros. Chinese platforms such as Aliexpress, which took advantage The shortcuts of the lawthey were especially affected. A year later The firm itself made it clear that the mark in its income had been evident. The shopping experience for consumers also changed: They could not trust at all (at least, initially) of the price that appeared on the products of its website, which Normally it was more expensive. A complicated future for Temu and Shein (and for their clients). The measures taken by the Trump administration will undoubtedly have a direct impact on the future of Temu, Shein and other Chinese electronic commerce platforms when operating in the United States. Price increases and perhaps delays in shipping times are expected. Bad news for China … and for US consumers who benefited from those Chinese products at competitive prices. And a jug of cold water for finish or google. But that will also have negative effects for the US economy. It is estimated that last year Temu invested about 3,000 million dollars In online marketing, and Shein has been flooding Instagram for years by advertising their garments at balance prices. Meta indicated last year that 10% of their advertising income came from Chinese companies, and now all that money – which of course invested in other US platforms – could fate.

We have a problem with heat in buildings. A Navarra investigation knows how to cool them without air conditioning

by

Every year we repeat the phrase that this has been the year less hot in the coming yearssince it is one of the consequences of climate change. One of the “traditional” ways that we have to refresh in our homes is with an air conditioning system, but poses an economic problem, because the invoices are not paid alone. However, a new Navarro study has managed to find a solution to refrigerate buildings with hardly any energy expenditure. Short. A research team, Formed by Amaia Zuazua Ros from the University of Navarra and Cristina Salazar Castro of the Luredera Technology Center, has developed a project to cool buildings without the need for air conditioning. Under the financing of the Government of Navarra and within the framework of the Navarro R&D System (SINAI)and with the coordination of Aditechthe proposal has sought to boost new passive cooling technologies through modules coated with nanomaterials, designed to eliminate heat from buildings without resorting to electrical systems. The challenge is not less. In the last 30 years, the energy consumption for the cooling of a home is It has tripled. These data, detailed in the International Energy Agency, have highlighted the impact on global electrical demand. For this reason, reducing this consumption without compromising thermal comfort is one of the great challenges of energy efficiency today. The operation. The system is much simpler than it seems. To explain it more easily, the researchers have identified a material that allows to cool the surface of the building, even when exposed to the sun. On the other hand, they have designed a structure to eliminate accumulated heat and thus improve air circulation on the facade by vertical dissipating modules. In addition, they have developed a system to easily adapt to different types of construction. The possibilities. Since the investigation they have detailed that the implementation of these modules in residential and commercial buildings would mean a reduction in energy consumption aimed at refreshing the environment. In addition, in cities with the large amount of solar panels that are being installed and The urban heat island effectthis new system will help mitigate high temperatures from these factors. However, the researchers, who are optimistic, have explained the challenges they have to overcome and how they should observe the long -term application. However, they have added that this technology represents a step forward in the fight against climate change and the design of more sustainable cities. Any other alternative? In the search for sustainable solutions for refrigeration without energy consumption, researchers from different parts of the world are betting on different approaches. An interesting example comes from Indiawhere a system based on recycled clay has been developed. Inspired by botijo ​​technology, this system uses clay cylinders to reduce the ambient temperature by up to 15ºC by evaporation of water, without the need for air conditioning.
