To batteries, it does not need to recharge and save millions of liters of diesel

by

While Europe looks with sweet eyes on Hydrogen train and In Argentina they already presume their solar trainAustralia boasts of her brand new electric train. Wait, how “electric train” when that exists for decades and It is called Ave? Because the Australian train has an important nuance: it works with batteries and is not connected to the catenary. The result? An “infinite train” manufactured with racing technology. And with a mission: save a lot of money in diesel. The ‘Infinity Train’. Mining in Australia is a huge business And companies invest to improve their infrastructure, thus being more competitive and efficient in every way. Fortescue (how difficult it is not to write “Fortesque” as in ‘Medievil‘) is one of those companies, and just announce who have completed the pilot trip of their “intinifo train.” Driven only by its battery system and without being connected to the current, this ‘Intinity Train’ has completed a trip of about 1,100 kilometers, and the most impressive thing is that it will have to do another 1,100 kilometers back without having to recharge. In fact, the idea is to make constant round trips without going through a plug. His trick is not called Solar panels Not anything like that: it’s called regenerative braking. Formula braking 1 AND. In 2022, Fortescue acquired 100% of Williams Advanced Engineering, a British company founded as a split of the Williams team of Formula 1, but focused on the creation of High performance batteries for formula E. The purchase was closed for 223 million dollars and the objective was Accelerate decarbonization in the company’s mining operations. One of the keys to Formula E, which also applies to the Formula 1 battery system, is the generation of electric power thanks to braking. It is like a dynamo that generates electricity with the engine in reverse, and in the case of ‘Infinity Train’, it is a tremendously magnified process. A huge asterisk. Because here the trick is that the round trip from Perth to the Pilbara region makes it loaded with materials, increasing the weight of the train and maximizing regeneration in braking. But, in addition, it is a route with a slope down. The slope on the road to the mines to the port is 600 meters, so the train has more than 1,000 kilometers to, with up to 34,000 tons of iron from the mines, generating electricity that compensates for the expense it can do. The return path makes it downloaded and ‘strip’ of that energy that has filled the batteries so as not to need an external load nor the support of the catenaries. And start again: they return to load the train, go downhill up loading their batteries and then climb the energy generated. The matter of money. In a huge continent and with the complicated terrain to install catenaries, it is a solution that has all the way, but the limitation is more than evident: the technology of this train can only be applied in situations as specific as that of long journeys in which the phase of being loaded with materials is done downhill. In other situations, it seems more complicated. But well, the company’s intention is to electrify its more than 50 transport trains for 2030 with the aim of reducing its emissions and, in addition, saving What Diesel costs. It is difficult to get the idea of ​​magnitude, but They speak to cut 82 million liters of fuel per year and reduce 11% of its annual CO₂ emissions if they electrify the train network. Electrifying the mines. From the company they affirm that this technology can be exported to everyone, and in the end it is another step in the MODERNIZATION OF MINES. It is precisely in this work environment that the electrification It seems very necessary not only to reduce emissions and that companies meet their objectives, but to improve the health of workers. In recent years we are seeing Betting for electric trucks and even automatedand the ‘infinite train’ adds to the trend, but with the great point against that it is a possible vehicle in extremely concrete situations.

We have clicks on ‘Cancel Subscription’ in Correos without thinking. It is just what many cybercriminals expect

by

The entrance tray of our email usually becomes chaos. Or, at least, in a digital landfill where messages that we have not asked or want. The reasons are simple: in almost any online procedure, however innocent it may seem, they ask us for a Mail address. From registering on the website of your electric company to connect to the free wifi of a cafeteria, the email always goes ahead. Then there comes a time when we decided to put some order in this personal space. One of the most obvious ways to start is to stop receiving emails that do not interest us. And for this, the most logical step is usually clicking on that link that some messages include at the end. It can appear as “cancel subscription”, “if you want to discharge, click here” or the classic “Unsubscribe”. The promise is clear: pulses and that sender disappears. That click to stop receiving spam can take us just where we didn’t want to enter The problem is that, although this function is legitimate, it can also be used for malicious purposes. According to DNSFilterthere are hundreds of cancellation links that actually lead to sites potentially dangerous. And that turns a harmless gesture – whispering an annoying email – into an entrance door for much more serious problems. A real example of the ‘Cancel Subscription’ button that appears in many mails. In this case it is presented as ‘discharge’ When we click to cancel a subscription we are leaving the controlled environment of our mail supplier. It takes us to an external website, and there begins the risk. The link may not have us to lower us, but to confirm that our address is active. Like those calls that hang instantly: If you answer, you know you exist. Something similar happens here, but by email. With that simple verification, who is behind can bombard us with more advertising to launch attacks on Phishing or more elaborate scam attempts. And that’s not all. There are other even more dangerous possibilities. Some malicious links can try to inject malware In our system. It is technically complex, yes, but not impossible. It is also frequent that they redirect us to pages that mimic legitimate services. There, we can end up introducing our credentials or sharing personal data under a false promise of cancellation. At this point, the doubt is inevitable: and then what do we do? Do we resign ourselves to a saturated input tray of trash emails? The answer is no. There are alternatives that allow to maintain control without assuming so many risks. The first step, as we have already mentioned, is to be aware of danger. Understanding it allows us to act with head. Let’s look at some others. Use the integrated function of cancel subscription. Some mail services, such as ICloud, Gmail or Yahoo, incorporate this option directly into their interface. It is a safer alternative than clicking on the message links. They usually appear at the top or lower part of the mail, and are part of the supplier’s environment, not the sender. Gmail (above), Mail of iOS (center) and Yahoo Mail (below) include integrated buttons to cancel subscriptions from the app itself, without the need to open links inside the mail Mark the message as spam. Another option is to point out the mail as unwanted. The effect is immediate: the message disappears from the entrance tray and the system learns to block future similar emails. But be careful, it is convenient to use this tool only when we are clear that it is spam. Otherwise, we would be training badly to the system. Use disposable email addresses. It is a very useful third way, which we analyze in depth in the article ‘How I learned to use several email addresses to keep all my protected digital accounts’. Logic is simple: if the problem is to share our real direction, the most effective thing is to avoid doing so. And for that there are tools such as the “hide my email” function of Apple. The option ‘Log in with Apple’ allows you to hide your real email and use a random address that you can delete at any time from ICLOUD Those who use apple brand devices can activate this function by registering in a service. The system generates a random direction that forwards the emails to the main account. If you start receiving annoying messages, you just have to check which of those temporary addresses are coming and eliminating it. It is worth remembering that this function is free, but those who have Icloud+ They can create new ones addresses at any timenot only during the registration process. This gives even more margin to protect privacy and improve security. All this adds to the classical recommendations: maintain updated software and have a protection tool against malware. They are not absolute guarantees, but security layers that make a difference. No, we will not be 100% safe. No system is. But we can be informed and take some measures to avoid falling into the traps that cybercounts have.

If there is something that biologists did not expect to discover is that billions of moths look at the stars to orient

by

Imagine having to travel a thousand kilometers to a place where you have never been. Now imagine you have to do it at night, without GPS, or maps of any kind. To finish curling the curl, imagine that you only have one chance in your life to do so. You don’t have to imagine it because we are not talking about a person, but of moths. The annual pilgrimage of the Bogong moths. This is the feat that billions of Bogong moths (Infusa agrotis) They perform every year in Australia. And scientists have just discovered that they are oriented looking at the stars. This discovery, Posted in Nature magazineconverts the Bogong moth in the first insect of which you have a record that uses a stellar compass for long -distance navigation, a skill that until now was believed reserved for animals such as some night migratory birds. The trip of a life. Each southern spring, these moths undertake one of up to a thousand kiometers. They hatch in the warm plains of southeastern Australia and fly towards a handful of cold caves in the Australian Alps to spend the summer (a process called Estivation). When the fall arrives, those same moths undertake the trip back to their breeding areas to reproduce and, finally, die. The big question that has fascinated biologists for years is how they do it. No one teaches them the way. It is a round trip that each individual performs only once. A team of researchers, led by David Dreyer from the University of Lund, had already demonstrated in 2018 that the moths were sensitive to the magnetic field of the earth, Like other animalsbut they suspected there was something else. They had their eyes on the sky. A planetarium for moths. To confirm your hypothesis, The team designed an ingenious experiment. They captured migration during their migration and introduced them into a flight simulator. This device, similar to a small planetarium, held the moth allowing him to beat the wings and turn freely, while a sensor recorded his flight address. The team did several tests: They canceled the magnetic field: using a coil system, they created an environment without magnetic clues. Thus they made sure that any correct orientation was due to visual signals. They projected a natural starry sky: under an artificial night sky, identical to the one they would see in the time of migration, the moths were oriented persistently in their correct migratory direction: to the south in spring and north in autumn. They turned the sky 180 degrees: In the final test, the researchers rotated the projection of the starry sky 180 degrees. The response of the moths was immediate and amazing: they invested their flight direction almost exactly 180 degrees. They project random stars: to make sure they did not respond simply to the light, they projected an image with the same amount of stars and brightness, but randomly distributed, without forming recognizable patterns. In this situation, the moths flew disoriented, without a clear direction. Unexpected. These results demonstrated without a doubt that the moths not only see the stars, but use them as a true compass to maintain a specific geographical direction for thousands of kilometers. It was already known that other insects, such as players, use the Milky Way to orient. However, they do it to move in a straight line and quickly move away from a lot of manure, a short -term orientation and without a fixed destination. The achievement of the Bogong moth is much more complex. Use the stars to “discern specific geographical directions” and sail towards a “distant objective”, something radically different and much more sophisticated. A brain connected to the stars. The researchers did not stop in behavior. They also analyzed the brain of the moths and discovered visual neurons that responded specifically to the rotation of the starry sky. Interestingly, these neurons showed their maximum activity when the moth was heading south, regardless of whether it was spring or autumn, which suggests that they have a wiring neuronal system to detect a fundamental light blue orientation. This does not invalidate its magnetic compass. In another experiment, the scientists observed that on completely cloudy nights, when the stars were invisible, the moths were still oriented correctly. The conclusion is that the Bogong moth has an incredibly robust and redundant navigation system. It uses both the Earth’s magnetic field and a stellar compass, probably using a system to calibrate the other or to take over when one of the two fails. There are still mysteries to solve, such as what stars or exact constellations use or how they compensate for the rotation of the earth throughout the night. But what is clear is that not only the ancient sailors looked at the stars to find their way. A tiny insect, on his only trip, also does.

Is olive oil the healthiest of all?

by

We tend to see olive oil, and especially the extra virgin or Aove, such as the cusp of the pyramid in terms of food fats. And not only in regard to his culinary excellence, but also in regard to his health impact. The big question is whether this pillar of the Mediterranean diet is up to this second aspect. Fats are not a necessary evil of our gastronomy, they are one more macronutrient for our body, which requires a source of lipids as required carbohydrates, proteins and micronutrients. Cholesterol and triglycerides Examples of these compounds are whose presence in our body is necessary. In addition to providing us with energy, lipids fulfill functions such as saving and transporting this or making messengers inside the cells, among others. On the other hand, problems can also cause us in some contexts, such as when cholesterol accumulates in our arteries. Nutrition is a complex area: different types of lipids can help us in different contexts and each food product can contain different proportions of each of the compounds that usually form them. Besides, Measure the impact on health of the consumption of some foods requires long follow -ups of the health status of the people who consume them. The notion that olive oil is superior to other sources of fat in regards to its impact on health is widespread. We owe this, at least in part, to the fact that this fat is one of the bases of the Mediterranean diet, considered one of the healthiest in the world. However, this does not necessarily imply that it is a healthy option. Fortunately, we have tools to evaluate this, as developed a few years ago by the Institute of Fat (IG), Research Center assigned to the CSIC (Higher Council for Scientific Research). After studying various culinary sources of fat, both animals and vegetables, the IG team developed an index (With values ​​between 0 and 100, being 100 the maximum score and with the 50 as a limit of the “approved”). To create the index, they explained at the time, those responsible for the study attended to the “dietary recommendations and health allegations of the main international organizations.” The result? Of the four best evaluated fats, three were derived from the olive. Virgin olive oil was The best valuedthus taking the maximum score, 100. As explained by the team responsible for creating the index In an article In the magazine Nutrients“One of the factors that contribute to the positive score for AOV (virgin olive oil) was its high oleic acid content.” The ranking of the fats The next three positions resulted from a tie with a index of 86. The fats that achieved this note were common olive oil, olive pomace oil, and linen oil. Sunflower oil, another usual in our kitchens received an index of 82, which placed it in the immediately following position, together with the sesame oil. In general, vegetable fats received evaluations superior to those of animal origin. Among them, the Fish fats They were better valued, and the beef tall and the lard (45), and the butter (32) the worst note received. Of course, these were not the worst valued: margarine received a worse index (14) and the list was closed by coconut butter, with a zero. Other experts seem to coincide with this evaluation. An example is those of the Harvard Medicine School, which They point that olive oil is rich in monounsaturated fats and that many of its benefits could come from there. These fats, they explain, have only one double bond between carbon atoms, which implies that they have less hydrogen atoms than saturated fats. This structure is responsible for these oils to remain liquid at room temperature. Howard E. Lewine, Chief Editor of Medicine of Harvard Health Publishing, pointed in a piece that “olive oil is rich in monounsaturated fatty acidscontaining around 75% by volume. When we replace saturated fats, monounsaturated fats can reduce your ‘bad’ LDL cholesterol. The benefits of olive oil have been attributed to its antioxidant and anti -inflammatory properties. ” In Xataka | Image | Umbe Ber

A third of Spain will be completely dark for one or two minutes. The astronomical event of the century is approaching

by

We still have the healthy envy of seeing the Spectacular images of the total solar eclipse that toured Mexico, the United States and Canada just over a year ago. It was an event that paralyzed a continent, especially in the so -called “totality strip”, the areas that were completely dark. Well, the next great cosmic appointment has Spain as a global protagonist. And we will not have to wait long. August 12, 2026. In just over a year the first total visible solar eclipse will take place since 1905, a unique opportunity in more than a century. Together with Iceland, which will enjoy 58 seconds of totality, we will be the only country in the world that can see all the phases of the eclipse. And let’s be sincere: in the middle of August, our possibilities of having clear skies are considerably greater than those of the Icelanders. Context. A total eclipse occurs when the moon aligns perfectly between the sun and the earth, projecting a shadow that immerses the lucky ones in a twilight darkness in the middle of the day. In the 2026 event, this shadow, the strip of totality, will have about 300 kilometers wide and will cross Spain from west to east, from Galicia to the Balearic Islands. The autonomous communities that will be under the shadow cone of the totality are Galicia, Asturias, Cantabria, Castilla y León, the Basque Country, La Rioja, Aragón, Catalonia, the Valencian Community and the Balearic Islands. Madrid will be right on the edge, with a fleeting totality in the north of the region. But the rest of the country will not stay empty and witness a very partial partial eclipse, with a coverage of more than 90% (and up to 74% in the Canary Islands, with Lanzarote as the island with better seats for the show). Almost two minutes. An essential tool to plan the observation of the eclipse to the millisecond is the Xavier Jubier interactive map. This resource is the gold standard for eclipses hunters because it allows you to click anywhere on the map to obtain the exact hours of each phase, the duration of the totality, the altitude of the sun in the area … The eclipse will start just before sunset. The totality phase will take place around 20:30 (summer peninsular time), with the sun already very low on the horizon. This turns observation into a race to counterreloj against sunset. In cities like Oviedo, the totality will last 1 minute and 48 seconds, only a few more moments in Burgos, León or the Island of Mallorca, which is emerging as one of the most tourist places where to see the eclipse (with the disadvantage that the sun is put before in the peninsular northwest). Safety first. As much as I tempt us, look directly in the sun, even partially eclipsed, can cause permanent eye damage. During all partial phases (before and after the totality), it is necessary to wear certified glasses to see eclipses or indirect methods to observe it. For the rest, it will be enough to look for a high observation place, with a horizon clear of mountains or buildings to the west so as not to miss the one that will undoubtedly be the astronomical event of the century.

To end the chaos of the messages without reading

by

There is a moment that can be especially annoying when opening WhatsApp: when we realize that a group has ‘uncontrolled’ and we have dozens of unrepted messages. While we were in a meeting, traveling or simply busy with something else, our contacts have made plans, they have changed their minds, they have argued and have even reached conclusions. Everything is there, in a mess of messages. And now, we have to dig between them to understand what happened. That task may be about to be easier. WhatsApp has just released A function that promises to change the way we read the chats. It is called “Message Summaries” and uses the technology of Goal AI To summarize, privately and automatically, pending messages. It is integrated into the messaging application. What exactly is this function? The idea behind the sets of messages is simple: when you enter a chat with unreposed messages, you can ask goal to summarize them by clicking on the corresponding icon. Nothing to go one by one. As we can see in the video, the AI ​​analyzes them and gives you a quick view of what has happened, as if someone made you an executive summary. A way to update without having to review the entire conversation. The goal itself raises it with a recognizable example: you arrive from a flight without wifi, you enter WhatsApp and you find too many messages to read. The summary helps you know what happened at that time, without having to read all the chats. The best thing is that the whole process is done privately, according to the company, without even WhatsApp or goal can access the content. With the focus on privacy. The key to this new function is in what Meta has baptized as “Private Processing”It is a system that allows the messages to be processed directly from the cloud, but without neither goal nor WhatsApp can see what is in them. It is a way of using artificial intelligence without compromising user’s privacy, in their own words. This system works with a confidential execution technology, based on safe environments (TEE), which allow AI to generate answers without keeping messages or sharing them with anyone. In addition, the summary is visible only for those who request it: the rest of the chat people will not know that this function has been used. According to WhatsApp, this function is not activated by default. Its use is voluntary and depends on each user. For those who decide to prove it, there is the option to configure which chats can be used with functions of ia like this, through the advanced privacy section. It is a mechanism that, on paper, allows limiting the scope of AI within the application. Available for now alone in the United States. The summaries function is beginning to deploy in the United States and, for the moment, only in English. From WhatsApp they ensure that its intention is to take it to other languages ​​and countries throughout the year, although for now there are no concrete dates for its arrival in Europe.

Airbus’s last military drone has been designed and manufactured in Spain. Its importance is not measured only in meters of altitude

by

Spain has just marked a milestone in the European defense industry. Airbus is over assembly of the first SIRTAPa New Generation Tactical Dron which has been designed and manufactured in the country. It is not just a technical advance: it is a declaration of intentions about the role that is sought to play in the development of strategic technologies. The Sirtap has been assembled at the facilities of Airbus Defense and Space in Getafe. The purchase was formalized by the Ministry of Defense in November 2023, with a request for nine complete systems composed of 27 aircraft and nine control stations on land. It is there where the first prototype has taken shape, and where it is now preparing to start the Test Campaign on Earth. The Spanish set by tactical drones The tests, which will evaluate both the structure and the main components of the system and the software, will be extended during the next months. The goal: to leave it ready for your first flight Before ending 2025at the CEUS DEL INTA trial center, in Huelva. According to Airbus, the new drone has been designed to fly in extreme conditions: it can operate between -40 ° C and 50 ° C, land on unpaid tracks and stay in the air for more than 20 hours in a row. To this is added an operational roof greater than 21,000 feet (6,400 meters), which would make it an ideal platform for long -distance recognition and surveillance missions. What Airbus poses with the Sirtap goes far beyond simple recognition. The drone has been thought of as A modular platform capable of adapt to different missions: You can monitor convoys from the air, act as an armed escort, detect electronic signals, participate in electronic war operations or control borders in hostile environments. It can also be deployed in emergency tasks, such as the search for vessels on the high seas or fire support. One of the most outstanding points of SIRTAP is that it has been designed without components subject to Itar restrictionswhich, according to Airbus, facilitates its export to international markets. This feature, together with its modular architecture, opens the door to future versions adapted to different environments, such as a naval variant or with complete weapons integration. A no less detail is that the system is also designed to interoperate with existing command and control networks. The Sirtap breaks into a segment with Several established actors. Uav like him TACTICAL HERONwith its ability to carry several useful loads simultaneously and operate from semi -sighed clues, or the Bayraktar TB2known for its missions in real combat and more than one million hours of operational flight. We also find al Falco Xplorerwith its autonomy of more than 24 hours and flight roof above 30,000 feet. Given that panorama, Airbus drone proposes a promising combination: Itar restrictions free, modular architecture, interoperability with European systems and operability in extreme conditions. Its focus is not to overcome figures, but to offer an adaptable platform, easily exportable and margin to evolve towards naval or armed versions. He has not yet taken off, but his road map places him as an actor to take into account.

The two most important chip companies in China have a problem: the 5 Nm have been choked

by

In the middle of last May Dr. Kiman expert in the manufacture of integrated circuits who has worked in Samsung and who currently investigates for TSMC in the US SMIC (Semiconductor manufacturing international corp) I was about to Start 5 nm chips production. And also that he planned to launch his first 3 Nm nodes equipped with GAA transistors (Gate-alall-around) in 2026. This company is the largest Chinese manufacturer of semiconductors, and has been working on the development of its own 5 Nm photolithography with Huawei. For these two companies to have the ability to manufacture their own 5 Nm chips is crucial, but they are having serious problems with this integration technology. Dr. Kim pointed in May that the performance by wafer that SMIC had reached in this node was less than 30%, but now there are two antagonistic means, the Canadian platform Techinsights and the Chinese newspaper SCMPthose that support the difficulties faced by Huawei and SMIC. According to Techinsights the new laptop Matebook Fold Ultimate Design Huawei incorporates a soc Kirin X90 manufactured by SMIC. Nothing striking here. What is surprising is that the chip of this ambitious team is not produced in the 5 Nm node. SMIC is manufacturing it in its second -generation 7 NM node (N+2) using an integrated circuit production technique known as Multiple patterning. This strategy in broad strokes consists in transferring the pattern to the wafer in several passes with the purpose of increasing the resolution of the lithographic process. China needs avant -garde lithographs, but endures thanks to mature chips The problem facing SMIC and Huawei, as we have explained in other articles, is that the Multiple patterning It has an upward impact on the cost of chips and the decrease in production capacity. These two Chinese companies have been forced to use this technique in their equipment deep ultraviolet lithography (UVP) because the prohibitions of the United States and the Netherlands prevent the Dutch company Asml from selling their machine their machines in Chinese extreme ultraviolet photolithography (UVE). The latter allow to produce more advanced semiconductors than UVP equipment. In Xataka The cure of some diseases "incurable" is already closer thanks to quantum computers According to Techinsightts, the new Matebook Fold Ultimate Design Matebook of Huawei incorporates a SOC Kirin X90 manufactured by SMIC In current circumstances it is reasonable to conclude that Huawei has not yet incorporated 5 Nm chips manufactured by SMIC in its most advanced equipment because the production of these integrated circuits is still very limited. This is what Techinsight and SCMP supports. And we think about it too. However, there is something important that we should not ignore. As I mentioned a few lines above, China needs avant -garde photolithographies To have the ability to make chips as advanced as those produced by South Korean companies Samsung or SK Hynix, Taiwanese TSMC or Intel or Micron Technology Americans. But, curiously, the Chinese semiconductor industry is surviving Thanks to mature chips. In fact, in 2024 it produced 12.5% ​​more than in 2023. It is not bad at all, especially if we are in mind that US sanctions and their allies prevent Chinese manufacturers of integrated circuits accessing UVE lithography equipment. And since 2024 they cannot buy more UVP lithography machines. For a good part of 2022 the production of China semiconductors suffered an important fall and did not begin to recover until the end of that same year. Of course, in 2023 this industry grew almost constantly, and in 2024, as we have just seen, the rebound was monumental, especially in the final stretch of the year. {“Videid”: “X81Felr”, “Autoplay”: False, “Title”: “A future without mole in China the industry changes the paradigm and we explain why”, “Tag”: “”, “Duration”: “182”} In this situation it is reasonable that we ask ourselves what kind are the integrated circuits that are producing the Chinese manufacturers. And the answer is very revealing: these are chips derived from mature integration technologiesusually of 28 nm or less advanced. After all, the semiconductors that we find mostly on electronic devices, appliances or cars, among other products, have been produced using them. More information | Techinsights | SCMP In Xataka | The US has declared the total war on Huawei: he does not want him to sell his chips for the most advanced outside of China (Function () {Window._js_modules = Window._js_modules || {}; var headelement = document.getelegsbytagname (‘head’) (0); if (_js_modules.instagram) {var instagramscript = Document.Createlement (‘script’); }}) (); – The news The two most important chip companies in China have a problem: the 5 Nm have been choked It was originally posted in Xataka by Juan Carlos López .

What experts explain about their maintenance

by

The heat arrives, the nights become sticky and, Like every summerit’s time to wake up the old air conditioning. But this year something is not going well. When lighting it, the first breath of air does not bring relief: it smells weird, as a moisture enclosed, as forgotten. Is it just unpleasant or is there anything else? A problem that floats in the air. Some experts They have coincided In The Guardian that if the air conditioning smells weird, something is wrong. It is not a matter of comfort: there may be health consequences. “These smells are usually a sign that there is accumulation of mold or dirt in the filters or in the equipment of the equipment,” He explained For the British media Amy Li, a professor at the University of Waterloo and a researcher of interior air quality. According to Li, the air that comes out of a dirty team is not only cleaner than the one that enters: it can be loaded with mold spores. The origin of the problem. Every time the air passes through the cold serpentine (the evaporator coil), the steam is condensed. If that water does not drain well, it is stagnant and becomes a perfect broth for bacteria and fungi. And yes, from there those smells come, like They have detailed From Bosch. Can it be avoided? It would be as manual, basic and regular maintenance. Robert Polchinski, a professor at the City Tech College in New York, explained in The Guardian that he must be washed at least once per season. If the air is very loaded – for example, in urban or pet areas – it may be necessary to clean it more often. You also have to review the coils (interior and exterior), make sure that the device drains correctly and is well level. At the end of summer, you have to keep it well, without leaning or forcing it. In addition, if you are going to use the air after months, ventilate the house with the windows open for at least half an hour while it is running, According to a series of measuring tips. More innovative solutions. In addition to maintenance, innovation is also pushing more efficient solutions. Researchers They are developing New materials capable of better absorbing moisture and improving energy efficiency, which could lead to devices that cool more and spend less. Can everyone stink? According to an expert climate videomany users neglect the outer unit of The systems Splitwhere dust and humidity can also accumulate. Even pipes can absorb odors from inside the house and return them to the environment. A little known but effective solution is to install a siphon in the drain system, which avoids the return of odors. And, of course, maintain a cleaning routine every three or four months. In the case of portable or window equipmentmaintenance is more direct, but also more urgent: they are usually more exposed to dust, and many users store them badly in winter, damaging the compressor or leaving them in positions where the water is not drained correctly. The importance of counting the years. Air conditioning equipment has an estimated useful life of between 8 and 10 years. But if you notice that the light of the light rises without explanation, that the coils freeze or that the smell does not go with a thorough cleaning, the time has come to change it. It is not just a matter of efficiency: the oldest equipment consume more energy, pollute more and cool worse. A less toxic summer. The air conditioning can be a lifeguard in times of extreme heat, but it can also become a risk if neglected. Regular maintenance not only prevents bad odors: it improves energy efficiency, prolongs the life of the equipment and protects health.

In addition to taking the first steps in a new market, the appearance of Tesla’s robotaxis in the streets of Austin leaves us many other readings. Among them how the company has approached autonomous driving, the use of artificial intelligence and how it takes advantage of its millions of cars in the street to advance faster and spending less money than competition. And that has its consequences. An unexpected brake. A Tesla Robotaxi that exceeds a crossing, which marches at the expected speed and that, without prior notice and without apparent reason, slows hard until it almost stops completely. What makes the car doubt? To the right of the intersection, in a street perpendicular to the march of the Robotaxi de Tesla, a police patrol is stopped. This does not hinder the march of the autonomous vehicle but, despite this, the car stops strongly. The video can be found on YouTube After the up of a user and Antitesla accounts have replicated them in X. Who has uploaded the video is Edward Niedermeyerjournalist specialized in the motor world in the United States and author of a book in 2019 on the birth of Tesla and the figure of Elon Musk, especially known for its critical positioning with the brand. Click on the image to go to the original tweet Fear of police. In Techcrunch They echo the video and put on the table the possibility that this type of behavior is due to learning that Tesla robotaxis have made of their own drivers. It is likely that, learning with the Huge database Of millions of cars on the road, the artificial intelligence that supports the movements of the autonomous car replicates the behavior of a good part of the humans: stop before a police car. This is what DGT defines how “Miron effect”. “Live millions of lives”. For a long time, Elon Musk presumes that the artificial intelligence used in its drinks from the vehicles that the company has in the streets. “It’s like living millions of lives simultaneously And see very unusual situations that a person in his entire life would not see, “Elon Musk said in the presentation of Tesla Cybercab. The company trusts not having to invest billions of dollars in the development of its total autonomous driving such as Waymo and Cruise because they use the data that their drivers yield with their vehicles. Thus, artificial intelligence learns from their behaviors and makes decisions that could be considered more human and less robotized. As human as stopping a police car or cover an intersection. A differential value. Tesla is confident that this approach is key to positioning itself as the best operator in the market. Although there is only a dozen robotaxis circulating through the streets, the data collected are not only obtained with trial vehicles, real data with real conductors are obtained, which should save enormous amounts of money and hours invested. Not only that, the company also aspires to have cheaper vehicles on the street. The combination of Artificial intelligence cameras It is a combo that, according to the company, allows them to save money on radars and lidar sensors, which make vehicles that are put on the streets a lot. Of course, it is not entirely clear that this is the right act because, as has been seen in some tests, The lidar sensor is much more effective in front of the cameras in concrete situations such as low visibility or with obstacles that can generate confusion to the cameras. A shadow. The latter is relevant. Mark Rober’s test showed that a car with cameras cannot discern safely If what is in front is a painted wall like a road or a real road. The lidar sensor, however, does detect the obstacle. Although this situation is not going to be given in real conditions, it does show us the effectiveness of the system to discriminate when it is facing a situation or not of danger. For example, when a Tesla Robotaxi confuses a simple shadow with an object On the road. This case, which is in A Reddit post Where all the errors of the robotaxis are being collected, it could be solved with the use of this system instead of trusting everything to the cameras.
