It is very likely that charging bar is more false than a wooden euro

You get home after a long work day, you throw yourself into the couch, you turn on your console, you release the game you are already vitiating. Well, no, because before your avatar, the map and your mount appear before you There is a load bar that must be completed. It’s normal, you’ll think. You have to load the textures, the game or whatever, go to know, but that bar advances, so something will be doing. There is little left. A little less. Oh, how slow, will now be with something heavy, surely. Well, most likely no. Most likely, this load bar will be false and its only goal is to play with your brain. Charging… Load screens, with their bar, an illustration and perhaps a text with advice or some of LoreThey were necessary. They served to entertain the player while the machine was looking for, read and loaded the game information on a console whose power was not, from afar, the one that the current devices have. It was a normal solution, because the other was a black screen or showing a half -load level that would leave a bad impression. Load screen of ‘The Elder Scrolls: Skyrim’ | Image: The Elder Scrolls Wiki However, technology has evolved and, currently, the few bars of progress that we can find in video games have more customs and psychology than useful. That does not mean that there are no load screens, because there are even if they are very well camouflaged, but the speed of the components has allowed us to use alternative methods to avoid them. It is false. If we are in the tail of an attraction in Port Aventura, we calculate how much a trip lasts and we look forward, more or less We can estimate how much is left to ride. In a process that is happening on a computer without us seeing anything, that is much more complex not to say impossible. Load screens and progress bars are the only way that the software has to indicate that something is happening, that everything is going well, but they are false. Progress bars are the only way to tell us to indicate that it is doing something, even if we don’t see it Because? Because players They don’t trust fluid progress bars. A progress bar that moves slowly gives a feeling of bad optimization, but a bar that moves too fast or an instant load could lead to think that something has gone wrong or that is not well done. Mike Bithell, developer and creator of ‘Thomas was Alone’, He already pulled the blanket in 2023 When he confirmed that the cargo bar is fictitious and that, really, it is the pulls that the bar gives that indicate that something is happening. Load screen of ‘Guild Wars 2’. Below right can the progress bar that, in this case, is circular | Image: Xataka Basically, the bottom of everything is that we expect to wait, if that makes sense. Rami Ismail, video game developer and well -known industry disseminator, confirmed In X that he had “worked on projects where we simulate load bars, we extended load times or made the load bars move artificially at unequal speeds.” Raúl Munárriz, executive director of the Now extinct Tequila Workshe also said that “I have never worked in a game that did not have a false load bar. The reais cause anxiety.” Is your whole life a lie? Yes and no. Making a progress bar is something complex because there are many processes that come into play during a load, as many as factors can make it more or less fast. We could make a progress bar based on how many files they have moved from x a y, but it would not be fluid because the files, surely, have different sizes. Nor would it work to do it based on the transferred data, since moving few heavy files is faster than moving many small files. And neither depends on how much it remains so that all the steps of the process are completed because it is enough for Chrome to open so that the state of the PC is altered and the times change. There is no perfect solution. The load screens are still there. Although they are not seen as such, many current video games continue to have load screens. More dynamics, more concealed, but visible. Normally, when a game artificially slows you it is a sign that, in the background, it is carrying what is coming later. A known example is that of the elevators of ‘Mass Effect‘, but we can also think about travel through the hyperspace of’Star Wars: Jedi Survivor‘, any medium of teleport, the time we run through Yggdrasil in’God of War‘, when we receive a call in’Gears of War‘That forces us to walk very slowly or in a kinematics that jumps at the right time to separate one level from another. The techniques for video games not to disappear with a load screen are wide and varied. It is very likely that the game is carrying elements in the background while we do something else without realizing it. Or to load and download the textures in real time depending on the distance and our position.

The Captcha had become an excellent tool to fight the bots. Until Chatgpt Agent arrived

In 2003 a young Guatemalan named Luis von Ahn published a unique study along with two colleagues from the Carnegie Mellon University and an IBM researcher. That project described an automated test that was easy to solve for humans but practically insurmountable for artificial intelligence systems. Those researchers called that test Captcha. The concept was simple and focused on the already famous Moravec paradox: there are things that humans do effortlessly – such as solving the visual puzzles that the captcha propose – but that the machines fail to solve. The idea turned out to be one of those between one million. Von ahn He ended up creating an improved version to which He called recaptcha that not only verified that you were human: I did it helping Train and perfect OCR systems. That other complementary idea was another unique moment “Eureka!” De von Ahn, and in fact he ended up making him a millionaire in 2009, the year Google decided to buy his service. Then he would dedicate himself to another equally striking project (or perhaps more): Duolingo. A dizzying (and juicy) evolution While doing so, the captcha continued to grow and evolve. Putting it more and more difficult for machines that gradually stated that perhaps those tests were no longer so valid. From those basic captchas we ended up moving to recaptchas of all kinds in which visual puzzles not only challenged the abstraction capacity of machines, but also helped to train no longer OCR systems, but artificial vision systems to better recognize cars, buses, zebra crossings or, how not, fire mouths. But artificial vision and intelligence systems also improved, and that struggle between these tests (Captcha comes from Completely Automated Turing Tests to Tell Computers and Humans Apart) and the machines became more and more interesting. It was a Singular cat and mouse game with spambotsand when some AI system managed to overcome a captcha or any of its variants, the puzzles became more and more difficult. The story has repeated again. He did this Friday. It was then that a User of the R/OpenAI community in Reddit published captures of Chatgpt agent overcoming without apparent problems one of the recaptchas more popular and used today on the Internet. This is the system TURONSTIL from Cloudflare, which presents a small box with the text “I’M not a robot“(” I am not a robot “) to click on it. It seems very simple and simple, but it is not so much for the machines. As indicated in Cloudflare, this recaptcha variant analyzes various signals such as the mouse movement, the time we take to click, the “digital footprint” of our browser, the “reputation” of our IP or some Javascript execution patterns. With them determines whether the user is a human being or is suspicious of being a bot. And if there is suspicion, the system presents after that first captcha another in which we do have to solve some type of visual puzzle. AI does not know if it is human, it only tries to operate as such The funny thing here is that Openai’s agent solved the problem in an obvious way: seeing what was on the screen to act accordingly, something that had not been easy until now. The agent was even narrating what he was doing, and while doing that step he showed the following text: “The link is inserted, so I will click on the” verify that you are human “click to complete the verification in Cloudflare. This step is necessary to demonstrate that I am not a bot and be able to continue with the action.” Or what is the same: The machine was self -healing like a human being. It is something unusual, but perhaps not quite strange considering that 1) AI does not really know what it says and 2) has been trained to speak (and act, at least in a limited way) as a human being. Operator, Openai’s previous agriculture, passed it really bad With these systems. Does this mean that captcha are threatened with death? Probably not. This is nothing more than another battle of that war between the bots and the captcha. One that for example we saw Another AI victory In October 2024 but it did not involve the debacle of this type of user verification tests. As they point out In Ars Technicathe captcha systems have not stopped evolving. From those blurred and deformed texts we go to recaptcha in which we had to solve visual puzzles of all kinds that lately force us not to identify traffic lights, but to place an image in a specific orientation – a increasingly popular system called Arkose MatchKey– Oa having to identify some element of an image that does not agree on it. In fact, the most recent captchas are no longer so much to prevent bots from exceeding that barrier to slow them so much that making brute force attacks with bots does not compensate. Captchas not as a barrier, but as a bots brake An article of those responsible for Arkose Labs, creators of Matchkey, made it clear that “There is no completely impenetrable captcha“, and that with their proposal what they intended was” to introduce an economic deterrence or cost proof for the malicious behavior of the bots. “Or what is the same: than to develop a bot that exceeds those captcha was so expensive that It was not worth it. Thus, we should not worry much in case the agents of AI can overcome this test, because surely they will appear captchas that continue to assume an almost impassable barrier for these systems. It is precisely the same concept with which it works THE ARC-AGI 2 TESTwhich measures visual understanding and abstract reasoning of AI systems and that is so complicated that the best AI models, which are also very expensive, do not exceed 4% of cases in the best case (O3-Preview). Will there come a time when those agents of ia get … Read more

It cannot be allowed penalizing with Asml tariffs

The commercial agreement signed by Donald Trump, the US president, and Ursula von der Leyen, the president of the European Commission, at the end of last week states that the majority of the products imported by the US and manufactured by Europe will have a 15% tariff. However, strategic products will not be subject to any tariff. And the photolithography equipment that designs and manufactures The Dutch Company ASML They have a strategic role for both Europe and the US. “We have agreed to zero tariffs for zero for a series of strategic products,” Clarifies the European Commission statement. “In this agreement all aircraft and their components are included, as well as some chemicals, generic components, semiconductor equipment, agricultural products, natural resources and critical raw materials. And we will continue working to add more products to this list.” The US is a very important market for ASML, so this exemption from tariffs benefits it. Intel, Globalfoundries, Micron Technology, Texas Instruments, Samsung and TSMC are some of its clients in the country led by Donald Trump. These last two companies are not Americans, but They have chips factories in the US. In fact, the exemption of tariffs is so important for these companies as for ASML because the latter is the only company that produces extreme ultraviolet lithography machines (UVE). And they need them in some of their plants to produce avant -garde chips. For Asml your effective monopoly is everything ASML has no competition since its first UVE photolithography team placed on the market. Japanese Canon and Nikon companies, their natural competitors, also tried to develop this machine, but failed in the attempt. The technical and economic resources that were necessary to make it possible were so large that they decided to retire from the struggle with ASML. Free road. Today the most advanced semiconductor manufacturing machines that we can find in the TSMC, Intel, Samsung or SK Hynix plants It produces them ASML. Currently his reign seems imperturbable. Canon has developed a team of nano -impression lithography that it seeks to compete from you to you with the UVE machines of ASML, but for the moment it is not clear that this technology will be able to rival The most advanced team of the Dutch company: the machine of High Opening Photolithography (UVE). Presumably thanks to it they can produce chips of less than 1 nm before this decade expires. The most advanced chips manufacturing machines that we can find in the TSMC, Intel, Samsung or SK Hynix plants produce ASML UVE photolithography equipment is extraordinarily sophisticated. The GPUs for artificial intelligence more advanced from Nvidia; The most powerful soc that Apple or the CPUs with the highest AMD performance are possible thanks to them. Of course, none of these companies make their own chips. They design them, but they are produced by the Taiwanese company TSMC using ASML UVE lithography machines. However, this European Corporation has not developed solo all innovations that have made its most advanced integrated circuit production equipment possible. One of its most important allies is the American company Cymer. This company founded in 1986 specializes in the manufacture of lasers and deep ultraviolet light sources (UVP) and extreme (UVE). It has a very close relationship with ASML for many years; In fact, the role that Cymer manufactures in lithography machines is so relevant than in 2013 ASML bought this company of San Diego with the purpose of investing in it to accelerate the development of the technologies involved in UVE lithography. Anyway, the transport of ultraviolet light from the fountain that produces it to the wafer is only possible thanks to the intervention of the mirrors that the other great ally of ASML designs and manufactures: the German company Zeiss. The role of Zeiss’s optical elements in these lithography equipment is crucial. And it is because they are responsible, leaving aside the most complex details, of moving the UVE light with a wavelength of 13.5 nm from the source that is responsible for its emission to the mask contained in the geometric pattern that is necessary to translate into the silicon wafer.

A millionaire spent a money to paint an exclusive RUF CTR YellowBird. I didn’t expect them to return it by doing the pine

Who plays with fire can burn, and who transports cars valued at millions of dollars also runs the risk of burning since the slightest carelessness can generate damage valued in thousands of dollars. This is what happened to a passionate owner of a RUF CTR ‘YellowBird’, one of the 80 more rare derivatives of Classic Porsche 911. After investing more than $ 150,000 in maintenance tasks and a total repainting of his painting, the valuable car It ended up rugged When downloading it from the truck that transported it before the stunned look of its owner. An icon of the 80s: the Ruf Ctr ‘YellowBird’ The RUF CTR ‘YellowBird’ is a modified version of the Porsche 911 Carrera 3.2 and developed by the German firm Ruf, specialized in converting the sports firm’s sports car In authentic beasts. Specifically, only 29 units of this RUF CTR ‘YellowBird’ were built, which makes it one of the most coveted cars in classic auctions, and a usual of cars video games. His exclusivity has led him to reach historical figures: in March 2024, one of these units was sold for 6.05 million dollars, As reported Topgear. Despite being based on the chassis of the Porsche 911, the Ruf Ctr It was very different In specifications. Its weight was reduced to 1,170 kg thanks to the use of aluminum in several body panels and carbon fiber defenses. It mounted a six -cylinder boxer engine with double KKK turbocharger, double intercooler and a DME injection system derived from the Porsche 962 competition. All of the above granted 476 hp of power and a maximum torque of 553 Nm, capable of exceeding 342 km/h in official tests, surpassing Ferrari F40 by then. Of “yellow bird” to bright black Be that as it may, the Ruf Ctr ‘YellowBird’ protagonist of this story is one of these 29 unique copies that originally went on the market with a body painted in a striking yellow color, as indicated by its last name ‘YellowBird’. Looking for a more elegant appearance, the owner resident in California sent his unit to the RUF headquarters in Germany so that, in addition to making mechanical adjustments, the car in bright black was repainted. For many collectors, modifying the original color of such an iconic model may seem risky, but in this case, the change added an even greater touch of distinction. As you can imagine, neither the transfer nor the restoration process was at all cheap. In total, the owner disbursed more than $ 150,000, according to details Road & Track. These types of restoration operations are common between collectors of high -value cars, which do not hesitate to send their vehicles even to other continents to ensure that they are in the hands of experts accredited by the manufacturer. A very expensive carelessness The tragedy arrived just when the owner was about to receive his Ruf Ctr back and with his new body color. When downloading it from the truck in the transport gondola, the car tires were not correctly secured, which caused it to slide through the ramp without control. Deportivo fell painfully from an approximate height of 2.4 meters, hitting the ground on the rear bumper, while the front was raised at a 45 degree angle on the truck. Touch the image to go to the original message The images of a six million dollar car making the pine on a transport truck soon became viral on social networks, and accounts like @johnclaywolfeshowThey shared them on Instagram accompanied by messages such as “Guess how many millions this little bird was worth.” In these photos you can see the transport operator inside the car at the time of the accident, observing impotent how a newly restored collection piece suffered damage that has not yet been evaluated at all but that, without a doubt, will mean an important disbursement for the person responsible.

What cars can circulate and which ones rest on August 2

Saturday. August 2, specifically. Moment to rest … especially if you are a car that is part of the restrictions of today does not circulate Sabatino. Because, indeed, today some cars will have to stay at home. What we are talking about is the program today does not circulate, that designed by the CDMX Ministry of Environment (Sedema) that forces to leave some cars at home with the idea of improving the quality of the air we breathe. With him, polluting emissions should go down. The system is simple: some cars, especially the most pollutants, have to stay at home. For them there are restrictions but the same Saturdays do not always stay at home. And, where it applies, some cars have to rest. And where is it applied? Specifically in the 16 mayors in Mexico City and in the following conurbation municipalities of the State of Mexico: Atizapán de Zaragoza Coacalco de Berriozábal Cuautitlán Cuautitlán Izcalli Chalco Chicoloapan Chimalhuacán Ecatepec de Morelos Huixquilucan Ixtapaluca La Paz Naucalpan de Juárez Nezahualcóyotl Nicolás Romero Tecámac Tlalnepantla de Baz Tultitlán Chalco Valley What cars and plaques affect the Sabatino today Taking all this into account, who should stay at home? Daily, restrictions are simple to understand, you can clarify all the details in the superior image. But not every Saturday, for example, they have to stay home on Saturdays. And some of them can move with total freedom but others have more problems. Which is it? Specifically, those who have total freedom and other weeks cannot move. Because, indeed, there are restrictions that alternate week by week. Because, indeed, one day as the following conditions can be applied today. Cars that can circulate every Saturday Cars that have to rest every Saturday Cars that rest on a Saturday yes and another no+ These restrictions, however, do not apply all day. At night they do not take into account and, therefore, are active between 05:00 and 10:00 p.m.. That is, at night we can move freely and without being afraid of fines. Clarified all this, should we take something more into account? Yes, as we told you, the Sabatino does not circulate today has the peculiarity that it does not always apply in the same way. Therefore, it does not always affect the cars themselves. First you have to look at the calendar (then we will see why it is important), then the hologram and, finally, the plate number. This is because Saturday is a special day in the program of today does not circulate Sabatino. It does not always affect the same cars in the same way. Those of Hologram 2, for example, cannot circulate any Saturday but those of Hologram 0 and 00 can do it every week. In that case, they have total freedom. And those of Hologram 1? Here is the crumb because a few weeks can move and others do not. In this case, the Saturday, August 2, 2025are obliged to rest those that the registration ends in odd number. This is because we are on the first Saturday of August and, therefore, it is these cars that must stay at home. Next week, the second week (PAR) will affect cars with a plate finished in torque. Of course, do not forget that there are some exceptions that allow some cars to move with total freedom. Are the following: However, there are some exceptions that must be taken into account because those cars can move with total freedom: Those that work for electricity, natural gas or are hybrid Those who have disabled plate All those dedicated to urban transport services (includes funerals) Those who offer school or passenger transport Those destined for public safety and/or civil protection In case of breaching these restrictions, the fine will be 20 to 30 times the unit of measurement and update (Uma), which is equivalent to 1,924.40 pesos and even 2,886.60 pesos.

California will test a “co -pilot of AI” at one of the most sensitive points of its electricity grid. Can go very well … or very bad

There is a less visible part of the electricity grid: the one that goes out on purpose. From time to time, whole teams must disconnect by maintenance. They are routine tasks, but their coordination and validation are decisive so that the system continues to work. In California, that work falls to the California Independent System Operator (Caiso) human team. Now, an artificial intelligence will begin to collaborate with them. Caiso has launched A pilot project with the firm Oati. The objective is to verify how a language model, similar to the one that drives Chatgptcan attend in a critical mission: manage requests – especially the scheduled – that come daily to perform maintenance in the network. Artificial intelligence to attend a task that cannot fail Many of these requests imply, although not always, temporarily disconnect key assets. If the information is incomplete or incorrect, the consequences can be felt in real time: from Network instability even alterations in the electricity market. Therefore, although part of the flow is already automated, the final review remains manual and exhaustive. Between 2020 and 2025, internal graphs show a high volume of applications, with clear spring and autumn peaks, the usual maintenance windows. That seasonality, added to the total number of requests, converts maintenance management into one of the most complex operating challenges in the system. The tool is called Oati Genie and is raised as a co -pilot of AI. Detect anomalies, extract operational information and suggest steps based on previous cases. To achieve this, it combines retrieval-augmented generation (RAG) with a system of multiple agents: operators formulate questions in natural language and receive contextualized answers, with links to documents and records that support them. The operator can, for example, ask what work could affect a certain electric route and obtain a history, procedures and public data such as those of OASIS (Open Access Same-Time Information System), the regulated base that centralizes technical and market information in real time. That consultation, which previously demanded manual searches, now comes with much more agility. The co -pilot does not decide for itself, its role serves to reinforce and expedite the human decision. If everything is going as planned, the tool will enter internal tests before the end of the year. Those who use it may report failures, limitations or improvements and help profile their evolution. It is not an isolated experiment, but part of a broader strategy to Apply to other areas of the system. The plan is underway, but there is still knowing if Oati Genie will fulfill what he promises. It may become a daily ally for operators; Maybe it’s just a step on the road to a smarter network. The only sure thing is that the electricity sector already explores that address.

Jeff Bezos’s space company has advanced Spacex in a key milestone to go to the moon and Mars: zero evaporation

One of the biggest obstacles to a mission to Mars is not the distance or travel time. It is the fuel. To send a manned ship, NASA estimates that dozens of Cryogenic propellant tons stored for weeks or months. But those liquids do not behave like on earth: in a vacuum, exposed to heat and without gravity, They are slowly evaporating even if the tank is perfectly sealed. That phenomenon, known as Boil-offforces to release the generated gas so that the pressure does not rise dangerously inside the tank. It is a constant loss that, in a long -term mission, can mean tons of tons of fuel lying to space. Therefore, developing tanks capable of preserving this propellant at safe pressure and without losses, which is known as zero evaporation technology, has become a technical requirement to go beyond the low orbit. Zero evaporation: the technical challenge that separates the orbit low from the rest of the solar system Blue Origin claims to have taken an important step To solve that problem. Jeff Bezos’ company has managed to maintain liquid oxygen and hydrogen in stable conditions, without evaporation, using Hardware flight prototype In earth tests (Blue Origin has not detailed whether it is vacuum thermal cameras or conventional banks). Dave clean announced itits CEO, as part of the lunar permanence program, stating that they already meet all the objectives set by NASA in this area. Click to see the publication in x The result is not less: we talk about conserving hydrogen at 20 Kelvin and oxygen to 90 Kelvin, two extreme temperatures, during sustained periods. This makes Blue Origin – which we know – the first private company that publicly and explicitly communicates a zero evaporation condition in cryogenic propelants. In the absence of this technology to vuele and demonstrate in orbit, what is achieved represents the most tangible advance so far towards tanks capable of storing liquid fuel without losses, a key piece to operate ships on the moon or Mars. Storing loss without space is not just a matter of good materials. It is a constant battle against physics. Even the best thermal insulation ends up giving in. Therefore, the path to zero evaporation goes through active solutions that cool the deposit from within. NASA has investigated two: The sub -housing jet and microgotes injectiontwo methods that allow to reduce the steam temperature and prevent internal pressure. Blue Origin has not detailed which of the two uses, but the logic points to the sub -deputy jet, The only tested method So far in microgravity by NASA. It consists of directing a very cold liquid jet where the steam is accumulated. When condensing it, it is avoided that the pressure rises and it is not necessary to release gas. It is a technologically complex system, but so far it has demonstrated greater efficacy and stability in test conditions. Long before Blue Origin announced its advance, NASA had already tested these systems In space. The ZBOT program, deployed aboard the International Space Station, allowed us to observe how a microgravity propellant tank behaves. One of its main discoveries was that the Interaction between the sub -housing jet and steam It does not follow the classic rules we know on earth. The Blue Origin cryogenic system during the ground tests of its zero evaporation technology In ZBOT-1, not only was it possible to control internal pressure with active mixture. Unexpected phenomena were also detected as cavitation, sudden formation of bubbles or flow alterations that could affect the stability of the system. That information – obtained with sensors, cameras and laser measurement systems – has served several companies, including Blue Origin, to design tanks capable of functioning stable in extreme environments. Spacex has not yet announced a zero evaporation solution as such. But that It does not mean that I am not working on it. In collaboration with NASA, The company has developed A cryogenic architecture oriented to reduced evaporation, which has already been validated in flight. In March 2025Starship made a Internal transfer of liquid oxygen in spacedemonstrating that he could move fuel and control his pressure without losing it excessively. NASA Artistic Recreation Although Spacex and Blue Origin are addressing the same general challenge – almaceinar propelants in space without losses – do not work with the same fuels or face the same level of thermal difficulty. Spacex uses liquid methane and liquid oxygen, while Blue Origin works with liquid hydrogen and liquid oxygen. That difference is key. Liquid hydrogen must be maintained to one much lower temperature than that of methane or even that of oxygen. In addition, hydrogen is less dense, more prone to escape and much more difficult to isolate. Achieving zero evaporation conditions with hydrogen is therefore a major technical challenge. The advance announced by Blue Origin is not only significant by the result, but by the type of fuel with which it has achieved it. When talking about going to Mars, you often think of rockets, habitats or space costumes. But one of the most serious bottleneck is in something much more basic: conserve fuel. In a long -lasting mission, the propellant is not used at once. You have to store it, transfer it and, many times, keep it operational for weeks without being lost by evaporation. That makes zero evaporation technology a key piece for both future interplanetary missions and missions Artemis To the moon.

We do not know if Bill Gates is the owner of this incredible supereyate for sale. What we do know is its price: 645 million dollars

During the summer it is usual to see the richest 1% on the planet enjoy the sea and the sun aboard immense floating mansions in the form of supereyates that anchor near paradisiacal destinations such as Balearic coasts or the Caribbean islands. Bill Gates is not very given to boat walks, so It is not a regular of the covers of those supereyates. In fact, the founder of Microsoft has never recognized being the owner of one, as they have done Jeff Bezos, Mark ZuckerbergLarry Ellison and Even Amancio Ortega. However, that has not been an impediment to be attributed to the property of one of the most advanced and expensive supereies in the world: the Breakthroughthe first ecological supereate driven by a pile of hydrogen that now is put on sale for 645 million dollars. Bill Gates and a superyate that has never stepped on Since the Breakthrough He left the shipyard that manufacturer Feadship has near Amsterdam in October 2024, his name It has been linked To Bill Gates. That I tend into account that neither the millionaire nor the manufacturer have at any time confirmed his property, and the millionaire has never been seen walking through his covers, so there is no evidence that Bill Gates is really the owner of the owner of the Breakthrough. That said, it is easy to imagine the reason why it is linked to this floating palace with Microsoft’s founding millmillonarium. Its sale price less than a year ago was 645 million dollars, so the ship was limited to a few fortunes that could assume such cost, and its subsequent maintenance. On the other hand, Gates’s commitment to him Clean energy development and innovative projects could intuit that this innovative yacht could be one of the Sustainable initiatives of the tycoon. However, today, it is not possible to confirm that the Breakthrough Be one of Gates’ whims. Breakthrough The first driven by hydrogen Beyond its spectacular design and dimensions, the greatest challenge for Feadship was to develop the propulsion system of the Breakthrough. Instead of conventional diesel engineswho was known as PROJECT 821 It is based on a liquid hydrogen cell system stored at cryogenic temperatures below -253 degrees Celsius. This technology requires a lot of precision management and design to guarantee safety and efficiency due to high hydrogen volatility. The machine room stands out because, to accommodate the storage, conversion and hydrogen management systems, much more space is required than in conventional propulsion systems. The entire electrical system of the yacht, from the propulsion to the lighting and air conditioning of the ship, is feed on the electricity generated by this clean fuel, leaving water as the only residue. This type of system is a pioneer In the nautical sector and represents for many experts a real advance and a reference in terms of Innovation in maritime transportation. Jamie Edmiston, Executive Director of the Yates Management Company that has it for salehe said in a statement collectedby Fortune than the Breakthrough It is “the most extraordinary yacht ever built and the one that will change everything.” A floating palace in a sea of luxuries In addition to being the first to incorporate a quieter and more sustainable technology with the environment, the Breakthrough has not neglected the luxury and exuberance demanded by the users of this type of ships. This superyte It is 118.8 meters in length and 19 meters of manga (wide). It has 15 luxury cabins with capacity for up to 30 guests, and space to house the 44 crew that guarantee personalized attention 24 hours. According The published by Forbes Australiaamong its comforts are five covers on the flotation line and two more under it, communicated with an interior elevator that facilitates access. Another peculiarity is that from their helmet 14 balconies are displayed that leave a panoramic view from the cabins. The main cover on the bridge is basically an apartment with two bedrooms, two bathrooms, dressing rooms, private gym, pantry, two offices with chimney and living room. In addition, it is equipped with a complete hospital for medical emergencies, a library with selected collections, private cinema, pool and jacuzzi and fully equipped gym. The designers of the British Redman Whiteley Dixon study used a light neutral, marble, rattan, smoked eucalyptus wood and oak details to create a luxury atmosphere and exclusivity. All for the modest price of 645 million dollars.

We have just measured the longest ray ever registered on Earth: 829 kilometers D

The rays are huge electrical discharges that in a fraction of second run through the distance between the clouds and the surface of the earth, a distance that can be several kilometers. However, lightning can go to distances a pair of superior magnitude orders. And this is one of those cases. The longest ray. The World Meteorological Organization has confirmed The longest ray observation ever registered. The electric shock toured a distance of 829 kilometers, with a margin of error of about 8 km. To put it in perspective, that is approximately the distance that separates in a straight line Barcelona from Seville. Although the validation by the United Nations Meteorological Office arrived this Thursday, the event occurred almost eight years ago, In October 2017in the United States. The great plains. The ray with its ramifications reached the skies of five states in the central and southern United States. The beginning of his “route” was on the east of the state of Texas, and his end was close to Kansas City, in Missouri. His tour and ramifications also made him pass through the states of Arkansasa, Kansas and Oklahoma. The region of the great plains where lightning was also known as Tornado Alleythe “Alley of Tornados”. This area, the OMM points out, stands out for being one of the areas “with the greatest storm activity known as Mesoescala convective systems”, which also makes it an ideal area for the formation of these “megarrayos.” For 61 km. As explained by the OMM, the new record exceeds 61 km the previous record. That ray also happened in the United States, but later, in April 2020, and reached 768 km, also with a margin of error of 8 km. In both cases, the detection and measurement of these rays was carried out through a method called Maximum Circle Arch. In addition, the OMM emphasizes that the 2017 ray was one of the first events measured with the help of the operational geostationary satellite for the study of the environment of the R (GOES-16) of the NOAA (National Oceanic and Atmospheric Administration). They also explain that this “megary” went unnoticed in a first analysis of the storm, and was not discovered until the review of the data compiled during the stormy episode. Now the details of the analysis carried out by the OMM team have been published In a working document of the Bulletin of the American Meteorological Society. Improving prevention. The study of the rays goes beyond establishing records that feed our curiosity about these violent phenomena. Improving our study tools and knowing these events better is key to reducing the risk they imply in several contexts, from aviation to forest fires. “Rays, although they are a source of astonishment, also constitute a great danger that is charged numerous lives every year worldwide, which makes these phenomena one of the priorities of the international initiative an early warns for all,” pointed in a press release Celeste Saulo, general secretary of the OMM. “This record highlights important issues for public security with respect to electrified clouds, (…) that may have serious repercussions on the aviation sector, as well as cause forest fires.” Carrying the accounts. The OMM is the institution in charge of Register extreme atmospheric events Throughout the world, an archive that has other records protected by great magnitude rays. For examplethe lightest ray registered lasted no less than 17 seconds (17,102 ± 0.002 s, specifically), and was captured in Argentina in June 2020. The direct impact of greater size was recorded in 1975 in Zimbabwe, and cost the lives of 21 people. However, the greatest indirect impact occurred in 1994, in Dronka (Egypt), and resulted in 469 people deceased when causing the fire of oil deposits.
