The rebirth of an old system that is illuminating remote villages in India: the hydraulic wheel

by

While the big cities They have opted for self -consumption through solar panels and even wind turbinesmany remote areas of the world still fight to have a renewable system. However, in Kashmir, they have found a cheap, effective and inspired solution in the past: the hydraulic wheel. An old advance. Surely the name of the hydraulic wheel will not come a direct image to the head, but if I describe a inn away from an village in the central European area, which had a large wheel shape that spinned with the water can be more enlightening. The fact is that they were important during the industrial revolution To perform mechanical tasks such as milling or hammering. However, its use began to decrease with the expansion of burning fossil fuels and the development of electricity. However, like fashions, everything comes back, and more if the original idea was good. So with the rise of renewable energies, hydraulic wheels have resurfaced as a viable option to produce electricity in a clean and continuous way in remote and impoverished areas. A new clean source. Initial investments in renewables usually have a high cost that not everyone can afford. But what if they turn to an old energy system? That is what a group of researchers from the Technical University of Munich thought that They have managed to install A hydraulic wheel in a town of Kashmir, India. The wheel in question measures about two meters and lets the stream water pass to produce electricity. In this way, it provides an uninterrupted energy source to the community, so it does not need centralized power, which was previously a problem with frequent cuts. In addition, the hydraulic wheel is accompanied by the use of other renewable energy systems, including the Decentralized microredwhich allows the inhabitants of the people to enjoy energy independence and resilience before a possible blackout. Self -sufficient One of the highlights of the hydraulic wheel is its high efficiency, reaching the 85% energy conversion. As for the assembly cost of this system, it is relatively low, around $ 1,000, so it makes them accessible to different impoverished rural communities. In addition, the design is available on the Internet for free. Only in rural areas. Hydraulic wheels are designed for rural and remote areas, specifically in communities that need a continuous and reliable energy source. This type of system offers a simple and economical way to generate electricity without depending on fossil fuels or intermittent energy sources. In addition, its environmental impact is minimal, since they do not emit carbon and, According to studiesdamage to aquatic life is reduced. While this type of technology has limitations and is not suitable for all contexts, its potential to improve the energy self -sufficiency of small communities could make a considerable difference. More for the world. The benefits of this technology are not limited to Kashmir. A similar system has been implemented in Nepal and a prototype has been developed in Tegernsee, Germany. In addition, in Northern Ireland, a hydraulic wheel has been restored with an old mill in Fermanagh County, which now supplies electricity to a restaurant.

It is a strategy and it is working

Work and pleasure are often Like water and oilthat are hardly mixed. However, LinkedIn has tried to break the laws of physics (labor) integrating a series of games into a social network very focused on the professional and workplace. At first that squeak a little slide through the Timelineof LinkedIn hoping to find publications of a former partner who has changed their jobs, or that a company is looking for candidates for cover a vacancy And suddenly, zas! A publication in which your co -worker presumes to have achieved the maximum score in a game. But, we hadn’t come to talk about work? Surprisingly, the play of integrating games is working very well. You do networking, you are looking for a job or … you start a game In May 2024, the company announced the integration of a series of free games accessible to all users registered on the platform. However, we talk about a corporate platform, so its focus is not offers triple A games, but maintain their productive spirit. From LinkedIn they point out that the objective of his social network “has always been to connect professionals around the world to make them more productive and successful. And, like the work world has changed in the last 22 years since the creation of LinkedIn, This has also done the way people connect with each other. “ That change of habits in communication and in the way to face the working day It has served as a support lever for the social network to pivot towards a more playful approach. “The objective of LinkedIn games is to encourage professionals to take a short break from work and stimulate their mind, while motivating them to connect with others,” they point out from the company. A recreation for the brain The catalog of LinkedIn games It is not very extensive. It is limited to four simple titles at a graphic level, but that propose different challenges at the mental level and a good dose of cognitive skills. Among the games that LinkedIn has integrated are: CrossClimb: A question and answers game in which you have to use clues to correctly guess each word of the stairs. The goal is to form groups of words based on tracks, in which only one letter differs with the previous word. Once you have organized the correct sequence of words, the clues will be unlocked for the beginning and end words. And the challenge is to decipher the words as quickly as possible. Pinpoint: It is a word association game in which you should try to guess (or “locate”) the common category or theme that unites a set of words. There are five clues to find out this common category. The challenge is to guess the category with the least possible number of revealed tracks. Queens: It is a logic game in which you have to fill in the grid so that there is only one crown per row, column and color region, not being able to coincide with any other crown of the attached segments. Tango: It has been the last game to join LinkedIn, and it is a logic game where you must fill a grid making sure that each row and column contains the same number of soles as moons. The complication is that there can be no more than two soles or adjacent moons, neither vertical nor horizontally. But what do these games paint on LinkedIn? According to Paolo Pasco, LinkedIn games editor the games seek to encourage Benefits of short pauses during the working day. “Various studies underline the importance of work pauses and cognitive benefits of the puzzles. Therefore, with our series of games we seek to offer professionals a space to make a brief pause and revitalize their mind. “ A investigation of the University of Exeter and the King’s College in London discovered the memory benefits that the crosswords, sudokus and other types of puzzles provide such as those proposed by LinkedIn in its recreational offer. Therefore, this may be a good way to foster a Status to take the brain to its “playground” in which abstract concepts and knowledge are connected to Generate new ideas. “It’s curious how something as simple as a game can be the impulse we need to return to energy with energy, desire to learn, connect and talk to others,” said Pasco. The fact of Improve cognitive abilitiessuch as the attention, concentration and mental flexibility, together with the social component that the social network provides, they make the games become a more socialization component between professionals or among classmates of the same office, breaking the ice in interpersonal relationships in The work spaces. According to A survey From Yougov, the puzzles and puzzle games are the most popular among users in the US, ahead of card games, action or adventure. Within these data, the puzzles were preferred, by far, by LinkedIn users, so it is not strange that the social network has chosen to integrate them into its platform. LinkedIn is still a business Beyond the productive component and Induction to labor interactions With the excuse of competitiveness in the games, the introduction of this new section on LinkedIn also Pursues an economic interest. In this sense, LinkedIn has followed the steps from The New York Times, which only a few months before also integrated a section of games in its application, continuing with the Wordle success. Such and As I counted Axiosthe games have allowed the New York Times to stabilize the number of subscribers to their platform, while the figures of the rest of their competition chopped. He Financial Times estimatedthat with the implementation of these games in LinkedIn a “record commitment” of 1.5 million content interactions per minute in June 2024 had been recorded. The LinkedIn Games Rachas system fosters the daily visit and sharing the results, so the return of users and their active participation in the platform increases, even if it is only for a few … Read more

Immediate energy and instant load

by

If there is something that surrounds us and what we cannot escape, that is plastic. Better or worseplastic is used for everything and we have abused so much that even Our semen is full of plastic. However, not all are the same and there is a very special one that was discovered in the 80s: the Poli (3.4-ethylendioxytiophen), or pedot, for abbreviation. We are talking about a special plastic because, although with limitations, it is a conductor of electricity. However, UCLA researchers have found The way to create a pedest supercadrator, and is something with potential to change energy storage and transmission of it. Pedot. Plastic is common in elements that need an electricity insulator. A simple example is that of loaders or plugs, whose coverage is a polymer. However, in the 80s a combination was discovered that allowed to create a conductor polymer of electricity. And he did it in normal environments, so the air and humidity did not take its toll. That is why it is used in many types of devices, such as OLED panelstactile screens, electrocromic elements, sensors, flexible conductive films or flexible solar panelseven experiments such as 2.0 brick with energy storage or a Electrical cultivation floor. Almost for everything. Pedot’s problem is that it transmits electricity well, but it is not good by storing it because it does not have the necessary surface to store large amounts of energy. Therefore, the bricks we talked about before gave to illuminate a LED (which requires an extremely low amount of electricity), not for much more. But of course, if the plastic was already revolutionized with the pedot, one could go one step further, right? Superpedot. That is what a chemical team from the University of California was asked, who sought to control the growth of the nanofibers of this polymer so that, in addition to conducting electricity, it can be stored. In something that UCLA chemists have baptized as “steam stage”, pedot’s nanofibers expand vertically. To get a more visual idea, it is as if it were a mantle of grass, which allows the surface of the material to be increased and, therefore, providing the polymer with better properties to store energy. And this growth has been achieved by adding a liquid formed by graphene oxide nanoparticles and ferric chloride on a graphite sheet. Once it is exposed to steam, that vertical polymer is formed. Plastic battery. By increasing the surface of the pedot, “we increase its ability enough to build a supercainer,” Comment Haher El-Kady, principal researcher of this project. It’s an achievement, it is clear, but … for what? Well, the idea is to create more efficient storage systems to address the problem of storage of renewable energy plants. It is something that, for example, is disrupting giant plans like China. Applications. And the great point in favor of this superpedot is that it can release energy accumulating electric charge on its surface. It is what allows you to load and download extremely fast, which makes it an ideal system for applications that require quickly released and storing it again, again, faster than a conventional battery. An example can be the flash of a camera, but also something much more practical for the energy transition of the automotive segment: regenerative braking systems in electric vehicles. A conventional battery stores and releases energy by slow chemical reactions, but this pedotal supercadrator can use that regenerative braking, for continuing with that example, to store a greater load of energy that, then, feed the wheels. Promising. The team states that its conductivity is 100 times greater than that of other commercial products based on Pedot, but also has a four -time surface, which facilitates that use as a supercainer. They also comment that it is very durable, supporting more than 70,000 load cycles, which makes them more interesting than traditional materials with greater wear in that constant load and discharge process. From the UCLA, they are convinced that “the use of pedot with graphene in supercaursors can help society meet their energy needs,” but we must continue investigating to check their properties in field work. And, yes, these supercaders are not a replacement of batteries, but a complement to applications that require a high loading and discharge speed. The battery remains the best commercial way to store that energy and the field of electric cars It is one in which superconductors can give a lot of play. One of the most interesting examples of use is the one that MIT engineers detailed a few years ago: convert roads into supercaders.

Every day thousands of people make fun without knowing about an empire when they have breakfast. THE RESPONSIBLE: THE COUPASAN

by

If something has demonstrated over the centuries, gastronomy is that kitchens serve more than elaborate tasty dishes. In the heat of their stoves they usually curdle culinary traditions, legends and mythslike the one that explains that every time we have breakfast a crucisan we are actually participating in a war. Because? Because with that seemingly innocent gesture we make fun of the defeat of one of the empires more influential of history. We explain ourselves. Cruasanos and wars? Yes. The relationship may sound a bit strange, but it comes with Google to find dozens of Blogsforums, magazines and Diaries that tell the same story: how the cross was created to commemorate the defeat of the Ottoman in Vienna at the end of the 17th century. To be more precise, the frustrated siege of the city by the great vizier Kara Mustafa which resulted in Kahlenberg battle and marked the beginning of the Ottoman decline in Europe. A great victory, a great cake to celebrate it. An epic story. There are war deeds that inspire poems, songs, operas, movies, paintings, novels; But … a cake? Why commemorate the siege of a city with a bun that thousands of people have breakfast throughout the world? The answer is quite simple: The legend He says that the Viennese pastries played a key role in the Ottoman defeat of 1683, so the guild wanted to celebrate it as best knew, kneading and baking mass. Of plots and noctámbulos. The story is of course worthy of the great romantic chronicles. Desperate to take Vienna, around 1683 the Ottomans began to think about ways to mock the fortification of the city. Some versions They say they decided to do so by excavating an underground gallery. Others, which set out to open tunnels to Place mines. In any case, the legend tells that, to dodge the vigilance of the Viennese, the Ottomans worked at night, among Quinqués and the moonlight, while their enemies slept. What the Muslims did not tell is that not all the residents of Vienna got into bed at night. There was a guild who worked every day from the sunset to dawn and ended up listening to the noise that the soldiers made with their peaks and shovels, which allowed him to alert the authorities and repel the enemy attack. What noctámbulos guild was that? Correct: The bakers. And the ‘Larousse’ of 1938 arrived. That this romantic dyes has reached us is explained for two reasons: centuries of oral tradition and the pen of the French chef Posper Montagnéwho in 1938 published an iconic work of universal cuisine, the ‘Larousse Gastronomique’. In addition to explaining how the crossings are elaborated, in its pages the scholar recounts the origin of the cake, echoing a version similar to the Viennese legend of the seventeenth century. In the work (at least in which it can Consult online) Montagné tells a similar story, although he places the plot during The Buddha site In 1686, not in the siege of Vienna of 1683. “The Turks besieged the city and to reach their hearts they excavated underground galleries. Some bakers, who worked at night, heard the noise made by the Turks and gave the alarm,” He recounts. But … why is it a mockery? Simple. Because when creating their new commemorative cake the Viennese pastries noticed A symbol From Islam: The growing moon. It is also explained by Montágne’s encyclopedia: “To reward the bakers who had saved the city, they were given the privilege of making a special cake that, in memory of the emblem that decorated the Ottoman flag, had to be shaped like a crescent,” duck The gastronomic encyclopedia. In summary: the new cake served to celebrate the Christian resistance and endurance of the city … and incidentally mocked the Ottoman forces. As Collect National Geographicwhen a Vienne devour one of those tasty cakes that emulated a moon really “ate the Turks.” The story was curious. The story, powerful. And for more inri it appeared ratified in a work of the prestige of the ‘Larousse Gastronomique’. So what was expected to be expected: the myth extended, gained strength and made the crosss become more than simple pastry. In their own way, they became a symbol. But is it true? The million dollar question. If gastronomy is good (in addition to satisfying palates), it is to create Myths and traditions of rigor more than questionable. Italian cuisine, Spanish either Japanese (To name only three examples) leave a few examples. And the Viennese legend of the Cruasan seems to be only that: a legend of truthfulness at least difficult to check. With you, the Kipferl. The story tells that the city’s bosoms elaborated two commemorative breads of the victory: the Kaiseremmela kind of “imperial panecillo”; and Kipferlwith a crescent -shaped. That this is the origin of what we understand today is however more than questionable, Remember From the Institute of Culinary Education (ICE). “He Kipferla baked panecillo from a dough of wheat with yeast, is common in central Europe, ” Clarifies the institution in his blog, in which he remembers that there are records that suggest that he Kipferl He ate already in the thirteenth century. Moreover, there are those who believe that their origins are older and more sweet in a similar way they can be seen in Magreb (Tchareke) or Türkiye itself, where the Ay çöreği. History and stories. “It’s almost certain that these stories are false,” assures Austrian chef Jürgen David. In fact they can be found Other stories that also relate the invention of the Capuchino with the Ottoman siege of Vienna. The popular Dunkin breakfast chain It echoes On its website for the legend that maintains that the famous coffee, with its characteristic color (similar to the habit of the Capuchin friars) it was first served in Vienna after its citizens found the sacks of coffee that the Ottoman had left behind. If true, the breakfast with which thousands of Europeans start their … Read more

Microsoft’s general director’s opinion about AI is unusual. And suspect how much the global economy will grow thanks to it

by

Satya Nadella, the general director of Microsoft, has intervened in the Dwarkesh Patel podcast. During Your interesting conversation of something more than an hour and a quarter duration This executive has touched many sticks of hot actuality for its relevance in the world of technology, but in this article we propose to investigate two of them: the artificial intelligence (AI) and the Quantum computers. And Microsoft objectively has much to say in these two disciplines. With regard to quantum computers, Redmond’s have surprised us with the presentation of a new architecture expressly conceived for these machines. Majorana 1 It is the first quantum processor devised to Use the exotic particle Theoretically proposed by the Italian physicist Ettore Majorana almost 90 years ago. Whatever the really important thing is that Nadella argues that it is possible that thanks to this Microsoft technology you can put a quantum computer equipped with millions of cubits and capable of solving a very wide range of problems in just four years. Satya Nadella believes that AI is not being evaluated correctly We are all witnessing the thrilling rhythm of development that is experiencing AI. In fact, during the last two years this technology is monopolizing the attention of the great powersresearch institutions, companies, and, of course, also of users. And nothing seems to indicate that this trend will change. Not at least in the short or medium term. Satya Nadella’s speech defends the importance of AI, but, surprisingly, this executive argues that her evolution is not being evaluated in the proper way. “Thanks to AI it is possible to increase productivity (…) The real reference point is that the global economy grows 10%” “For me it makes no sense to self -proclaim (human beings) that we have reached some milestone in the field of General Artificial Intelligence (AGI for its English denomination). It is only a manipulation of the performance tests that, in my opinion, is meaningless (…) the winners will actually be the industries that Be able to use this technologywhich, by the way, is abundant. Thanks to it it is possible to increase productivity, so the economy grows at a faster rate. The true reference point is that the global economy grows 10%”, SATYA NADELLA has pointed out During his conversation with Dwarkesh Patel. It is worth not overlooking two important points of this statement from the head of Microsoft. On the one hand it is evident that it is moderating the enthusiasm that They have triggered Openai and other companies in the always controversial land of the AGI. And, what if possible is more relevant, proposes a bar to measure the development of the different AF -is being used, and that requires evaluating its direct impact on economic growth. But there is something else. Something very important. And it is that Nadella has suggested, as we have just seen, that AI could trigger a global economic growth of 10%. We will see if the time finally is right, but a priori does not sound at all far -fetched.

Why an astronaut was obsessed with failure (and the lesson that leaves us to improve our productivity)

by

Most of us avoid thinking about failure. And when we do it is usually something inevitable, but ephemeral, because we flee from that thought. Chris Hadfield, the Canadian astronaut who commanded the International Space Station, did exactly the opposite throughout his career: Metustically visualized each possible failure. Because? To prevent it. What seems like a paradox (focusing on failure to achieve success) makes some sense. Precisely in its workplace, space, an error can mean death. There, NASA dedicates Much of the training time to practice the response against emergencies. It is not pessimism, but strategic preparation. It is a method applicable to everyday life and on the earth’s surface. When We visualize what can go wrong in a project or an important decisionwe are reducing anxiety and uncertainty. And improving our response capacity. It is like having a mental GPS that has already calculated alternative routes before encountering the first obstacle. But there is a trap: The key is not to become obsessed with the worst scenarios, but to turn them into contingency plans. Hadfield did not limit himself to imagining disasters, but developed specific responses for each one. He turned fear into something productive. The method can be reduced to three steps: Identify fissures. Develop a specific response for each one. You practice those answers until they become automatic. This method makes sense and works because Eliminates the surprise factor of failure. When you have already visualized a problem, and practiced the answer to it, our brain processes it as a similar situation, not as a crisis. Hadfield came to command the International Space Station preparing obsessively for everything that could go wrong. We, at a more mundane, literal and metaphorical level, we can achieve our goals by systematically proof all possible fissures. It is not something that guarantees success, but it is a way of thinking that it will make us more competent already proof of failures.

The most precise map of the Earth has been created by a team of physicists. And it has little to do with what we are used to

by

One of the great challenges of cartographers trying to create world maps is the impossibility of recreating the surface of a sphere in a plane. At least faithful, precise and legible. The map on disk. He last attempt For creating a map that minimizes the distortions associated with the representation of the surface of the sphere in a plane has given a curious result: a plane whose authors compare it with a vinyl disk. The reason is that on this map our planet is represented as two circles, one showing the northern hemisphere and another the south. The map has imperfections, but its authors consider that it is the most faithful projection to date. “You can’t do everything perfect,” pointed in a press release Richard Gott, one of the authors, “a map is as good in a thing as it may not be to represent other things.” A problem of (more than) half an millennium. Humanity has known for thousands of years that Earth is spherical, but this rarely was a problem for two reasons. The first is that the cards only included the Eurasia and Africa region, the Americas, Oceania or Antarctica did not enter the maps until To this we must add that the maps were not so precise that the distortions of This problem They will charge relevance. Many times they didn’t have to be: it was not until the modern era that cartographic precision began to be vital, especially for those who threw themselves into the sea. From Mercator to Winkel Tripel. Mercator’s projection is a of the oldest And even today is one of the most used. This projection was created in the 16th century by Gerardus Mercator with the intention of facilitating transoceanic navigation. While this map maintains precision in the shapes of the elements such as seas or countries, The sizes are significantly distortedmaking areas close to the poles more with respect to those located in Ecuador. A lot of history. Centuries of work have led less distorting maps. Among them, the authors of this new plane include the Winkel-Tripl, a projection created by German cartographer Oswald Winkel in 1921. This map is not so helpful for navigators and still has distortions around the poles, but represents a commitment . It is also the representation used by the National Geographic Society. “Disco” version, showing here on the obverse and the reverse on the same plane. Gott et al. Scoring the maps. If the plane is not perfect, why do your authors think it is close? In 2007 David Goldberg and Gott itself created a maps score system based on six criteria: local forms, areas, distances, flexion, asymmetry, and cuts. The punctuation system is inverse: a spherical mapamundi would have a score of 0.0, and from there, any added distortion would add greater score. The punctuation system was introduced into An article In the magazine Cartography: The International Journal for Geographic Information and Geovisualization. Being work of the same team does not result from this letter to be able to minimize the score. If the Winkel-Tripl had a score of 4,563, the new map Reduces error to 4,497 points. The “trick.” The new projection presumes to achieve better scores than its alternatives in the six variables stipulated by Gott and its team, however there is one in which it emphasizes particularly thanks to a trick, that of continuity. If we take any map we will see that there is a cut, usually located in the Pacific Ocean, between Asia and Oceania, and the Americas. This is a great source of distortison according to Gott’s criteria and his team. Your solution: a disc with two faces. The Gott map is raised to present itself in the form of an disk, which gives continuity to the “cut” we see in Ecuador (and that, that, The authors explain The map could also be placed along the zero meridian). From Earth to the confines of the cosmos. The authors of the new map took advantage of their new projection to Cartogarafiar Other other elementsfrom the planets of the Solar System to the celestial vault, including a story map Microwave cosmic background.

The Coffee World Cup exists and Spain has put their hopes in a barista in Vigo: Marcos González

by

Making coffee is simple, but prepare a good coffee It is something that has crumb. When you start investigating the peculiarities of each preparation, coffee varieties and instruments for get all the juice to the grainsyou discover that it is an art. There are those who take this to the highest level, so much that there is even a coffee World Cup. Or Baristas, rather. This is the World Coffee Challenge, and this year the Vigo Marcos González will represent Spain in this curious competition. The Coffee World Cup. If there is an Excel World Cupit is logical that there is such a competition around One of the most consumed drink on the planetafter the water, of course. In fact, there is not only a competition, since the World Coffee Challenge is an umbrella that embraces various disciplines. One of them is the World Barista Championship in which, obviously, the best baristas in the world break up to see who prepares the best experience. Because here not only does the technique matter, but to tell a story to the jury. It seems boring from the outside, but it is quite interesting to see the skills of the competitors. One of them is someone who has worked a career as a coffee disseminator, James Hoffmanwho rose with the trophy in 2007 and what he has done follies how to prepare a Donut coffee. Coffee fest. As in all competitions, there are a series of previous rounds, and to find the Spanish representative, a few days ago the Coffee fest. More than a simple competition, it is a coffee celebration with the best coffee with milk preparation or the best filtered coffee, others that test their skills with the Latte arttasting tournaments and other activities. James Hoffman was in this year’s edition, as well as other disseminators and youtubers such as Hedrick Lance. And, regardless of being a meeting point in which coffee lovers share knowledge and experiences, it was the framework of the national competition of Baristas. Vigo quality. 18 professionals from all over the country gathered to prove their skills, and the best was the Vigo Marcos González. It was not the first time that he raised with victory, since in 2018 and 2019 he was also considered the best barista in Spain. His proposal this year was an experience that ‘told’ crucial moments of his career, as they detail Our companions from direct to the palate: Origin: Inspired by its connection with the Esmeralda farm in Panama, this concoction reflects its first experiences with Coffee Geisha, a variety appreciated for its unique flavor profile.

An underwater cable that will give more than one return to the earth

by

Two current trends in geopolitics are the Rare earth and submarine cables. The first because China has the pan for the mango and are essential for the construction of today’s world. The second because that world cannot be understood without them and we are seeing that they are an element of pressure in A scenario like the Ukraine War. Submarine cables are the perfect example of globalization, the element that allows practically all countries Let’s be interconnected and that we can enjoy telephone lines, internet or streaming systems as we do today. Our oceans are full of these cables And it is companies such as goal or Google who are investing greatly in increasing their number due to the boom of both streaming and AI. Precisely a goal, which was already working to display a huge cable of more than 7,000 kilometers, has just announced one that will go around the world: A megacable that will interconnect more than 50,000 kilometers. Waterworth Project: New Generation Cables The Earth has a circumference of about 40,000 kilometers, this being a fact that helps us understand the magnitude of the infrastructure that plans to display Mark Zuckerberg’s company. In a releaseMeta has commented that this underwater cable is the most ambitious so far for its part (and by anyone, go) and that, when it has been completed, it will link the five main continents through more than 50,000 kilometers. The name of the project is Waterworth and the idea is join the two coasts of the United States with Brazil, South Africa, India and Australia. They have not talked about numbers, but it is a multimillion -dollar investment and will be carried out in several phases over the years. To get an idea, the Google cable to join Japan and the west coast of the United States It will cost about one billion dollars. The intention of the goal is to strengthen its position in the digital highway segment in order to boost their artificial intelligence. It is something that the company is very involved and, in this way, it will reinforce its presence in the sector. These submarine cables are composed of other cables, normally 8 or 16 fiber pairs, but there are also some with 24 pairs. Waterworth will be of this last class and will become the longest of 24 pairs. And it is not a plan on paper: they are already working on the path that will travel the cables, with the intention of protecting them as much as possible, since some sections will be 7,000 meters deep near high risk failures. Vital highways (such as the Ukraine War is demonstrating) Something they are also paying attention to is the cable covering. Meta has commented that they will use improper burial techniques in the shallow areas near the coast, where ships usually damage these systems, but are also looking to protect them in the face of “other dangers”. What other dangers? Well, we have recently seen in the Ukraine War, where Cuts have occurred in these cablessomething that has caused instability in some systems. Due to its importance, and the stage in which the cuts were given, at first it was believed that Russia and China were behindbut it seems that the explanation is another: dragged anchors that caused the cuts by error. Be that as it may, that at first it would be thought that the cable cut was part of a pressure measure in a war scenario, it reflects the importance when protecting this type of systems. In the end, as a goal states in its statement: they are essential now, but they will be even more in the era of the AI ​​we are entering.
