Solar panels have been determined to conquer every building span

by

Self -consumption It has been growing As renewable energies have been integrated into the home. The fact of power Save on the Light Invoice has made more users decided to put solar panels on roof either balconies. However, it seems that converting a house into an energy generator does not know limits. Short. Canadian company Miterx has launched Solarrail, a system of solar railings with system BIPV (Building Integrated Photovoltaics) Designed, as the name implies, to integrate into architecture and generate energy. The integration of solar energy. This system is designed to integrate photovoltaic into the urban architecture and design, such as The company itself has detailed. In addition, its main advantage is that it takes advantage of the space of the boats of the balconies, transforming them into solar energy generators. Integrated panels. Miterx has launched Two versions of the Solarrail: a transparent version (60%) and an opaque. The panels are made up of bifacial solar cells, which allows to capture sunlight both in the front and in the rear. On the one hand, the transparent model has a power of 105 w, on the other hand, the opaque model reaches 390 W. In addition, the system includes support bars, and hidden wiring Solar rail | Miterx Heat is not concentrated. The installation of solar panels in urban areas, although it promotes energy self -consumption, can contribute to the increase in temperatures in cities. A study has demonstrated That these panels absorb up to 90% of solar energy, turning only 20% into electricity and releasing the rest as heat. However, this is when we talk about a solar panel on the railing, while we will have to wait as these integrated railings can avoid the phenomenon “Urban Heat Island”. So is it better than a solar balcony? BIPV systems avoid phenomena as mentioned above. In addition, in this case, as they are bifacial panels, they capture light from both sides, increased efficiency. However, integrated solar panels can affect the risk of fire, As a Norwegian study explains. The distance between the module and the solar balcony can reduce riskwhich does not happen with an integrated system. Forecasts. Solar energy is evolving beyond traditional roofs or balconies, with innovations such as solar railings. These solutions take advantage of the architecture space to continue growing. For its part, European regulations will require that from 2030 All new construction buildings are zero emissions. In this way, we will have to see how technological innovations in the energy sector will grow to comply with the guidelines.

China wants to revolutionize the hypersonic flight of airplanes and missiles with an explosive ingredient: magnesium

by

China and the United States are immersed in a race that is not fought on the mainland, but in the air with a common goal: to achieve speeds of more than 7,000 km/h. Both have several hypersonic airplanes projects With potential both military and civil And, although the US seems more reserved, China from time to time goes out to the arena to talk about Your technological achievements. The latest is an engine capable of going to Mach 6 thanks to a fuel formula with a special ingredient: magnesium. Mach 6. When we talk about hypersonic speeds, what we use to measure it is the Mach 1. is the one that represents the speed of sound, established in 1,235 km/h. Thus, a Mach 2 speed would be twice the speed of sound. Well, what are testing At Beihang University in Beijing it is a technique that allows to double the thrust of current hypersonic engines to reach Mach 6 and higher speeds. It is difficult to get an idea of ​​the amounts we talk about, since we are talking about speeds of more than 2,000 meters per second or around 7,000 kilometers per hour. It would be like going from Madrid to New Delhi in an hour. That journey, currently, has between eight and ten hours. EITHER cross the Atlantic in three. Scramjets. The objective of the researchers is to redefine hypersonic aviation thanks to a combustion technique that, as we read in South China Morning Postpractically doubles the thrust of a scramjet engine. It is the abbreviation of “Supersonic Combustion Ramjets”, these Ramjets being reaction engines created to reach Mach 3 speeds. To function, the air enters the engine at high speed. They are motors without turbines that compress that air at supersonic speed (do not slowly subsuite like Ramjets) and then the fuel is injected. It can be hydrogen, but also kerosene, which is mixed with compressed air and, as a result, a supersonic jet of hot gases that propels the vehicle is generated. When it occurs for the first time, it is when the sound barrier is broken and something similar to an explosion is heard. “Secret” ingredient. The problem of Scramjet engines is that, at extreme speeds, the energy generated by fuel is stabilized, but adding magnesium to the fuel formula, the thing changes. The Chinese team chose magnesium being a metal with a violent reactivity. When the kerosene burns it generates residual, but when they inject magnesium dust, that CO₂ acts as an oxidant lighting the magnesium particles. Yang Qingchun is the project director and comments that “magnesium does not need atmospheric oxygen”, so those magnesium dust particles react in explosive shapes with the residual gases that were previously wasted, now releasing an additional energy. China hypersonic test vehicle Evidence. And they have tested. Under conditions that simulate a Mach 6 to 30 kilometers altitude flight and using commercial aircraft fuel, magnesium injection increased the thrust by 86.6% with a combustion efficiency of 65.1%. This allows to increase the 613 Newtons-second motor thrust per kilogram at 1,126 Newtons-Second per kilogram. At that speed, the kerosene burns practically completely, the magnesium dust turns to the contact and releases the heat between two and three times faster than only the kerosene. But speed is not the only advantage. Something crucial is not to overheat the turboreactor, so researchers have studied how to optimize the process to increase performance without a temperature increase. Thus, it is the kerosene that acts as a refrigerant of the motor walls through regenerative cooling. The magnesium, which is added later, burns in a “storm of supersonic fire”, according to the researchers, which is stabilized thanks to an optimized flow route that, in turn, helps to achieve that more powerful thrust. Challenges. But of course, the higher the speed, the greater the challenges. We have already commented that the temperature is something that plays against supersonic ships Because they must resist friction that makes the temperature rise above 1,500 degrees Celsius. In addition, at more speed, more turbulence. The team states that this supersonic turbulence entails the risk of an unequal dispersion of magnesium dust inside the postquemor. If there is a bad penetration of the particles, or an irregular injection, the thrust gain falls to almost 20%. It is something that causes the engine to be very unstable. In addition, those magnesium particles that “exploit” are a double -edged sword. On the one hand, the explosion generates that violent reaction that increases the thrust, but at the same time the particles become microcuchillas that can damage the engine. Therefore, you have to investigate engines with the capacity to resist impacts inside. On the other hand, you have to stabilize magnesium injection because it is postulated as something ideal to quickly reach hypersonic speeds and maintain them, but a ship fluctuates in speed, it is an unstable fuel. They have added nitrogen gas to stabilize the entrance of the particles, but the team confesses that it is “as difficult as threading a needle in the middle of a hurricane.” Projects. It is something that China will continue working because it is the team itself that states that it is not something only for airplanes: Yang comments that its design can reduce the launch weight or extend the range of missiles. They will try to inject magnesium on a nanometric scale to see if it is more efficient, but it is clear that it is a project that interests the country. And, yes, China has already tested higher speedsbut what they are looking for is more stability and the way to change between speeds at pleasure, not in such a linear way. And he does it because the United States is also working on it. Not only in aircraft like Blackbirdbut also in systems such as Dark Eagle, a missile with a range of more than 3,000 kilometers and capable of reaching speeds greater than Mach 17 (about 20,000 km/h) with systems to … Read more

Volkswagen lost 6.7 million with each one who sold

by

On the Paseo de la Fame of the luxury supercoches, there is a star reserved for a car that, although their wealthy buyers had to put on the table 1.7 million dollars to remove it from the dealership, every time a unit was sold, its manufacturer lost 6.7 million dollars: The Bugatti Veyron. Bugatti Veyron: A luxury and speed icon The Bugatti Veyron He was born in 2005 of one Ambitious idea: Create the faster, powerful and luxurious car in the world. And what if they got it. Ferdinand Piëch, the visionary architect of the current Volkswagen group and grandson of Ferdinand Porsche himself. The passion for speed and luxury was carried in the DNA. This supercar mounted one of the engines that has given the most joys to Bugatti. It’s about Your brutal W16 of 8.0 liters and four turbos, with which it was able to accelerate as a rocket and break cut speed records above 406 km/h. This figure became almost a demand for The desire for “revenge” of the brand for a speed record in Le Mans. The name of the Veyron also closely linked to Le Mans’s career, since he honors Bugatti’s pilot and engineer Pierre Veyronwhich in 1939 won the 24 hours of Le Mans with one of the brands of the brand. The brand took Six years to develop from the Veyron for the challenge of implementing an engine capable of developing 1,001 hp of power and 1,400 nm of touch. To keep the temperature of such a beast at bay, engineers had to integrate 10 radiators. The exclusivity of the Bugatti Veyron was not only noticed when paying the 1.7 million dollars that cost Each unit. Each game of tires, especially Designed for the Veyron For Michelin, it cost the whopping $ 38,000 and had to replace every 4,000 km. On the track and maximum speed, the life of the tires was limited to about 15 minutes before disintegrating. Something that would rarely do, since the 106 liters of their deposit gave for 12 minutes. Without a doubt, a car with maintenance Far from the reach of many pockets. The Veyron was not just speed. It was also extreme luxury. Every detail, from materials to labor, was of the highest quality. Having a Veyron was like having a work of art on wheels, a demonstration that you could afford the best of the best. Aspire to One of the special editions Del Veyron was already another level, and supposed to pay more than 2.7 million for some of them. A ruinous business for Volkswagen But here comes the surprising part: despite its millionaire sales price, Volkswagen lost money with every Veyron who sold. And not little, precisely. Such and as they counted in Technology.orgthe financial research firm of Wall Street Bernstein Research published a report in which they assured that the Volkswagen group lost about 6.24 million dollars for each Bugatti Veyron that was sold. However, later the authors of that report admitted that this figure should be taken cautiously because it was based on approximate estimates. Paradoxically, the explanation of this financial fiasco is given by its engineering and design success. Volkswagen did not spare on expenses to create the perfect car and for it They invested 1,620 million of dollars in their development. Last prototype of the Bugatti Veyron The negative part is that Bugatti only sold 450 units of his Veyron in the 10 years he was on sale, so the investment in R&D was higher than the brand recovered selling cars, which was a financial fiasco. However, although in absolute terms, the development effort of the Veyron was greater than the income of its sale, the technology that was developed for that jewel of engineering then served as the basis for all A supercoches lineage. Its legacy has served to knock down all the speed records until it reaches 490.48 km/h that reached the Bugatti Chiron Super Sport 300+ In 2019, such and as he collected Car and Driver. Volkswagen was willing to assume those losses because he wanted to demonstrate his ability to create the Best Support Support in the World. Although, the Veyron was not a financial success in itself, it managed to position Bugatti as a reference brand on the map of luxury supercoches. A “failure” that, in the end, turned out to be a great triumph, although very expensive.

Six gadgets that I never thought I would need and have improved my daily life in 1000%

by

During these last years I have bought a good amount of Gadgets or accessories. I am not going to lie to you, some have not liked anything and I expected much more of them. But there are others who I liked much more than I thought, and I have come to give them even daily utility. Therefore, I have gathered the six accessories that I liked the most than I bought in recent years. Logitech MX Vertical by 69.94 eurosa mouse with ergonomic design that offers a very pleasant comfort in hand. Logitech G Pro x Tkl Lightspeed by 181.22 eurosa spectacular mechanical keyboard with macros configuration and quite silent and pleasant keys. Huawei Watch Fit 3 by 113 eurosone of the best activity bracelets I have had so far. Tomoc backpack by 69.99 eurosa travel backpack with a lot of ability to avoid always traveling with a suitcase. TP-LINK TAPO P100 by 10.90 eurosan intelligent plug that I am taking a lot. Soundcore Space Q45 by 94.99 eurossome bluetooth headphones that I love. I use them to work and for personal use. Logitech MX Vertical When I started having more and more discomfort in the elbow and the arm when using the mouse, I decided to prove how the work worked Ergonomic mice “Conconcreously the vertical ones,” of which so many good opinions had read and heard. I tried luck with the Logitech MX Vertical And I can’t be more delighted. Although the inconvenience has disappeared completely, I still use it practically daily, alternating it with the Logitech G502 Hero. Right now it is found by 69.94 euros. I paid something more for him and it is worth every penny. What I like most is that it is very comfortable in hand, I do not miss anything other mice (as a greater number of buttons), The battery lasts a barbarity And I use it on several computers simultaneously, since it has multidispositive connection. The only “paste” I could put is that it is not compatible with the Logitech G hub software, but with logi options+. * Some price may have changed from the last review Logitech G Pro x Tkl Lightspeed I never thought I would spend more than 50 euros on a keyboard, but I made the leap to mechanical keyboards with the Logitech G Pro x Tkl Lightspeed. Is very expensive (181.22 euros), But I am very delighted with him. I was looking for a mechanical keyboard that did not make too much noise By pressing the keys, and I chose quite well – not before seeing several dozen videos about certain models. The most useful of this keyboard is that It has macros —The “F” keys become macros when pressing the “FN” key – and I have it both for certain shortcuts and for text writing (text can be added so that by pressing the key it is written automatically). The battery also lasts a barbarityyou can customize the lighting key per key and includes a multimedia wheel at the top. As added, I have placed a resting so that writing on the keyboard is more comfortable. Specifically I bought Razer for TKL keyboards, although it is already discontinued. This, also of Razer, is practically the same and costs 33.46 euros. Logitech G Pro x Tkl Lightspeed * Some price may have changed from the last review Huawei Watch Fit 3 Throughout these years I have had several activity bracelets, and although at the time I liked it enough I was fed up that the straps were broken within a few months. Therefore, I decided to buy the Huawei Watch Fit 3 In its version Velcro strap And it is a pass. It is, from afar, the best activity bracelet that I have had so far and can be found by 113 euros in Amazon and for 109 euros in the official huawei store; The latter also includes a gift strap. The rotating crown is a success; It is super useful and vibration feels very good. It includes several sensors to monitor physical activity, but what I like most is that it includes many sports modes and some training. It even comes with Heating and stretching routines. It can be found slightly cheaper in other strap configurations, but I already tell you that it is Velcro’s a thousand laps that I have had so far. * Some price may have changed from the last review Tomoc backpack I usually travel a lot, so a year ago I was looking for backpacks of great capacity not to always take my suitcase. After shuffling many options, I finally opted for the 40 -liter Tomoc. Its price is 69.99 euros (I paid much more) and fits everything. It does not come with as many pockets as other alternatives, but it does not need. In the inside we have two large compartments: one that I use for clothes and another that I use for the laptop, the tablet and the loaders. It also has other smaller pockets for documentation and little else. The most interesting is the construction: It feels like a very rigid and resistant backpack and the rear is paddedso it is a very comfortable backpack to carry, even if we carry a lot of weight. In addition to the backpack, I also bought the compact bandolera Tomoc Compact X-Pac that I always use on my trips (and for when I leave home). There I always carry my Ereader Kobo Clara 2E, the Nintendo Switch, headphones, keys and much more. In this case, we can find it for 47.19 euros. Although he says it is a bandit, its compact design is closer to what is a fannyry, but with enough space to carry many things. 40 -liter Tomoc Backpack * Some price may have changed from the last review TP-LINK TAPO P100 Another accessories I use every day are my two smart plugs TP-LINK TAPO P100. Certain appliances, loaders and the work team turn it off during … Read more

All the resources that we can potentially extract from the moon, illustrated in this graphic developer

by

Mars has become the long -awaited objective of space exploration. So much that the New “Manifest Destination” of the United States. This is something that has sown doubts about the future of Ambitious Artemis mission for go to the moonbut beyond to satisfy scientific curiosity, our satellite has a lot to offer as far as resources are concerned. And in this graph prepared by Visual Capitalist We can what resources we can get from the Moon and what is the degree of confidence we have for each of them. Scenery. The graph is more informative than attractive, that must be recognized, but clearly exposes not only what are the main resources of the moon, but the possibilities we have to take advantage of our current technology. Thus, we can see that there are resources that we have well measured, such as the amount of regolito or solar energyothers not calculated so precisely, and we can see clearly if they are resources that we can recover for land use right now or if they are resources that are out of our reach. Because, of course, one thing is to collect resources, and another very different to be able to pack them correctly and return them to the earth. Resources. The data that they have used for the elaboration of the graphic respond to those of the geological study that the United States developed in 2022 and there is something important that must be taken into account: we are at the dawn of something that seemed science fiction, the Mining on the Moon. There is a large presence of metals on the moon such as iron, titanium, aluminum or magnesium, but also the coveted silicon, which is the Base of our technology industry and solar panels. There are also ice-3, which is a Fuel potential for nuclear fusionrare metals, oxygen, and it is estimated that there is water, but not in a liquid state, but present in the form of ice in the craters that are permanently shaded. The main resources and their status are clearer in this table: resource Current classification Recoverable with our technology Reserve in 30 years Solar energy Measured Yeah Yeah Helio-3 Dear No A stranger Regolito Quantified No Yeah Oxygen in Regolito Quantified No Yeah Hydrogen retained water Quantified No Likely ice -shaped water Minimal or without evidence No A stranger Lunar mining. Before Elon Musk’s arrival to revolutionize space exploration at the governmental level, there were Plans For NASA to send drilling equipment to the Moon to establish a permanent extraction plant for 2032. It is an objective that may have been complicated taking into account recent events, but it is also something that would conflict with the Treaty of ultra -resters. That mining on the Moon is, as we say, very interesting due to the deposits we believe we have located in the satellite, but article 11 of the 1967 Treaty establishes that all the natural resources of the Moon are “common heritage of humanity.” In addition, “it cannot be subject to national appropriation through claims for sovereignty” and those resources “cannot be owned by any state, intergovernmental or non -governmental international organization, national organization or non -governmental entity or any natural person.” Interpretation of lunar soil by ESA Regolito. Returning to the graph, there are two resources that stand out on the rest, both because we know of their existence and because they are the simplest to take advantage of current technology. One of them is lunar dust, curiously. It is called a regolito And it is a carpet of rocky materials that has a couple of useful applications. The first thing is that it is composed of a large amount of oxygen and metals, elements that could be separated from dust to use them in other purposes. Through electrolysis, we can separate oxygen from metals and, although oxygen on Earth is a byproduct, on the moon it can be vital as a source of life. The dust obtained as waste can be used as construction material for brick or roads. There are other projects to take advantage of this abundant lunar resource: Improve regolito fertility through bacteria to be able to grow on the satellite floor. In fact, this soil fertilization is key not only for the colonization of the moon: also for the Martian adventures. Solar energy. Now, from the resources that we can extract from the moon and on the moon, solar energy is the most interesting. The reason is that we could start extracting in the short term because we have the technology to do so. In lunar poles, the sun is visible for long periods, so energy could be generated continuously because there is no rain with rain or clouds (this rainy March we have learned The price of rain in the generation of solar energy). To transmit that energy captured to Earth, lasers or microwave could be used. Projects. There are some in progress. On the one hand, we have Luna Ring, a Japanese project that wants to place a 400 -kilometer wide solar panel belt and 11,000 kilometers long (an absolute barbarity) around Ecuador lunar to send 13,000 theravats to the earth continuously. Is more than we currently need. On the other hand, the European Space Agency had the GE⊕-LPSa project that would consist of a lunar station with panels manufactured from lunar resources. Because yes, the regolito also has silicon and other metals that could be used in situ to make panels. Here the idea is to use that energy to feed the lunar bases. And another project is Blue Alchimist de Blue Origin. Again, taking advantage of the regolite to create panels, it also seeks to generate energy in an unlimited and constant way. Challenges. Now, they are not simple or cheap programs. Focusing on the most accurate project, which would be to produce energy because we know that there is light and we know how to send that energy to the earth, we … Read more

A “small ice age”

by

“No realistic adaptation measure can face such fast temperature changes under a collapse” of the Gulf current. In recent years we have discussed a lot about The weakening of the AMOC and about the consequences that, especially for EuropeI could have all this. And yet That study phrase that returned the old fear of the researchers to the fore: the one that says that we do what we do, THE END OF THE AMOC It would be a catastrophe of unsuspected proportions. Everything will happen too fast. The amoc is The oceanic flow that runs from north to south in the North Atlantic basin. The process begins with sinking to the cold water background in front of Greenland and the movement of this south. The replacement of that water with a warmer (which flows on the surface to the north) allows to transfer heat from the Gulf from Mexico to Europe. The cold comes. The problem is that the importance of this current in Europe is capital. Without it, both Western Europe and East of North America would cool very significantly. We would see how a “generalized cooling throughout the North Atlantic and Northern Hemisphere in general“That the temperature would collapse in Europe, how they would strengthen” from the winter storms, with more and more powerful explosive cyclogenesis “and a much more snow (taking a lot of productive lands from the market in a matter of years). The change would be (will be) brutal and we know it in good ink. The story is full of examples. The small ice age was, according to NASA a period that began around 1550 and consisted of three cold peaks (around 1650, 1770 and 1850) interspersed with relatively warm intervals. Those peaks were extremely hard and are key triggers of three of the great geopolitical conflicts of the continent: the wars of religion, the French Revolution (and Bonapartism) and the revolutions around 1848. But also the fall of the Ming dynasty in China. These years are full of anecdotes, from the Swedish troops crossing the frozen sea in the Swedish war Until the suspicion that the cold was the Calve factor that caused the wood of the Stradivarius to be denser than usual. Hunger, pain and suffering. In National Geographic published in his day A small summary of historical testimonies where it can be verified that “aldeano aldeans (survived) based on bread made with ground nuts stall The floor was too hard to dig. We are not in 1600, of course. And that shows, especially, in our ability to ‘adapt’ and to use internationalist networks to ‘cushion’ local or regional changes. No one can argue that, in recent decades, our systems have improved: beyond our assessment, Andalusia now has double irrigation that in the 90s in similar climatic circumstances. However, as the authors say, it is very difficult to imagine some scenario in which a climate change of that draft does not lead to a deep economic, political and social crisis throughout the entire continent. And that, of course, is the worst problem of all. Right now, all of Europe is in a hurry for a warmer climate, so that The Sahara extends to the northso that The rains and snow become more rare. At the time the Gulf Current is stopped (And it is increasingly clear that it will stop) We will be headed to the opposite situation. But without time to react. As the old woman said (and probably apocryphal) Chinese curse, we seem destined to live interesting times. Image | Juanedc In Xataka | In 536 the sun began to shine less than the moon.

What cars can circulate and which ones rest on March 29

by

Indeed. We are on Saturday and you know what it means: today does not circulate sabbatino. Because punctual, once again, the restrictions of this program arrive that tries to improve the quality of the air we breathe. What are we talking about? Indeed, today does not circulate and its specific restrictions on Saturdays. The project designed by the CDMX Ministry of Environment (Sedema) Try, as we said, to improve the air we breathe with a very simple measure: leaving our cars at home. Radical or not, that must decide each one. What is true is that, where it applies, there are some cars that cannot circulate. A measure that applies to 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 Having all this in mind, everything we have to know about today is not collected in the superior image. But there are some details that are well taken into account and that may not be entirely clear. The first thing we should know is that, throughout the week, the hologram and the plate number is what defines who and when they can circulate. On Saturdays, yes, it is broken and the restrictions are the same but those affected are not always the same. This leaves us in the following situation: Cars that can circulate every Saturday Cars that have to rest every Saturday Cars that rest on a Saturday yes and another Restrictions, yes, do not apply all day. They are active between 05:00 and 10:00 p.m.. That is, at night we can move freely and without taking into account any type of restriction. Once we have these basic concepts in mind, how can we completely dominate the Sabatino today and thus not fall into the fines for breaking it? Remember that some cars will not be able to leave home. Specifically, we talk about cars with hologram 2. In this case, the plate number does not matter, cars with hologram 2 cannot move. On the contrary, cars with hologram 0 and 00 are not necessary to take into account the plate number because they can circulate freely. So which have more problems? The cars with hologram 1. In this case, they rotate every week. Thus, the Saturday, March 29 It will be the cars with hologram 1 and plaque finished in odd number those that rotate because we are on the fifth Saturday of March. Of course, we cannot forget that there are some exceptions that go beyond being able to circulate freely at night. Thus, the following 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.

XAI of Elon Musk acquires X, also from Elon Musk: a movement that almost no one saw

by

Elon Musk has announced that xai, The artificial intelligence startup founded in 2023 to compete with Openaihas acquired X, the social network previously known as Twitter. As explained, the operation has been closed through a exchange exchange. The assessment. During the last months, much has been speculated on the value of XAI and X, with figures that changed according to the different financing rounds. With this transaction, there is already a clearer reference, at least according to the Musk version: XAI becomes valued at 80,000 million dollars, while X stands at 33,000 million. This last figure amounts to 45,000 million if 12,000 million are added in debt, always according to the businessman himself. {“Videid”: “X8N07SL”, “Autoplay”: False, “Title”: “Elon Musk and his obsession with the letter x that you did not know”, “Tag”: “Webedia-Prod”, “Duration”: “495”} Musk presents Xai as “one of the laboratories of the leaders in the world”, although he is still far from his main rival. Openai reached an assessment of 157,000 million dollars in 2024 And it could reach 300,000 million With the support of SoftBank. Chatgpt It remains the reference, although Xai has updated Grok with functions such as image generation and their own app. What changes with the acquisition? According to Musk, the operation will allow “combining data, models, computer, distribution and talent.” In practice, integration was already evident: Grok was integrated into X for months. What changes is the legal and corporate structure. In Xataka The fever for the chatgpt images is “melting” the OpenAi GPUs: the company has already begun to limit access It will be necessary to see if this restructuring implies offices, transfers or equipment mergers.

Japan has just found a way to drastically accelerate the construction of train stations: print them in 3D

by

3D impression continues to make way in the world of architecture. After seeing the first houses and even data centers 3D printednow is the turn of rail infrastructure. The latest novelty It arrives from Japanwhere they have already installed a train station built with this technology. According to those responsible, the main advantages against traditional methods are speed and sustainability. As can be seen in the images, we are not facing a station that impresss its size or monumental design. On the contrary: it is a simple, functional and compact construction. At first glance it may seem plastic, but in reality it is printed in concrete. The structure, of less than 10 square meters, is based on several reinforcement bars and has two openings for the passage of passengers. The first 3D printed station in the world The structure was printed a few kilometers and was subsequently transferred in a truck to Hatsushima Station, in the Wakayama Prefecture, about 96 kilometers south of Osaka. There the final assembly was carried out. Naohiro Ohashi, spokesman for Jr West Japan, explained to NHK that “Normally it takes about two months in building a station of this size ”, and that in this case the priority was the speed to complete the work.
