In 1978 Christopher Reeve was chosen to play ‘Superman’. He got so beaten up that he literally couldn’t fit into the suit.

In the mid-seventies, superman He wasn’t just a character: he was DC’s goose that laid the golden eggs and a bet that could make or sink the first great modern superhero blockbuster. Producers Alexander and Ilya Salkind wanted a “serious” and grandiose film, far from the tone camp from the sixties Batmanbut they also knew that any setback would be a historic embarrassment. Too big to fail. In that scenario, DC, suspicious, imposed conditions of the strictest and he monitored the project as if it were a surgical operation, because the underlying problem was not to make a film: it was to make it with a guy in tights and a red cape and get the public to I will look at him with respectnot like a meme. Two years of casting. Thus, the search for superman perfect became the great bottleneck: it began in 1975 and continued until February 1977with hundreds of tests and a growing sense of desperation. There was, as usually happens in any great production, a star wish list that seemed more a festival poster than an audition: Robert Redford, Paul Newman, Warren Beatty, Clint Eastwood, Steve McQueen, Burt Reynolds, Charles Bronson, James Caan, or even Nick Nolte. In fact, there were many more, in addition to proposals that today they sound delirious by pure marketing logic, as think of Muhammad Ali or even in people outside of interpretation. It turns out that each option failed for something (if it wasn’t cost, it was age, image, accent or fit in general) and the message was clear: without Superman, there was no movie. The definitive twist. In the midst of that chaos, Christopher Reeve arrived from the New York theater as an answer that did not fit the cliché of the “big name” that the producers were looking for, but did fit the essence of the character. The casting director was pushing his candidacy against the team’s inertia, until he was finally given a real opportunity. When Richard Donner, the film’s director, saw it, the trial was as clear as it is uncomfortable: Reeve had the height, the face and the aura to be Superman… but he was also too young and too thin (“a stick”were the director’s words) to fill a suit that required visible strength, not just presence. Even so, in that test (between nerves, the heat of the spotlight and a still ungainly appearance) something that no one could copy became evident: the potential to make Clark Kent and Superman credible in the same person. The actor before opting for his role in Superman Stop being a “stick”. Reeve got the role with an unspoken demand which was actually an ultimatum: he had to physically become Superman, and do it quickly. The producers even suggested use fake muscles under the suit to “trick” the camera, a typical solution in the cinema of the time, but he refused, because he understood that credibility was not built with filler, but with transformation. The movie needed the body to say “superhero” before the character even spoke, and Reeve assumed that the job was not just to act well, but to look impossible without falling into excess. Darth Vader as trainer. Here comes the anecdote that seems invented by an advertising department: the man inside the Darth Vader suit, David Prowse, also a bodybuilder and instructor, was the one who was in charge of sculpting to Superman. Donner called it like someone activating a emergency plan: “we have a Superman” and we have to build him against the clock. Prowse trained Reeve for weeks with a routine focused on gain mass and functional strengthsolid enough to withstand flight harnesses, exhausting days and the symbolic weight of the character. And in the process a perfect story was born to sell the film: the most intimidating physical villain of the moment molding the definitive hero of the decade. The “obsessive” transformation. The method was so simple as brutal: eat a lot, train thoroughly and not allow yourself to lose weight even for a single day. Reeve put himself on a high-protein diet, with four meals a day, shakes and vitamins, and with an almost paranoid discipline: skipping a meal meant going backwards, and going back was a disaster. The idea he repeated was very clear: the actor’s inner work is useless if the exterior does not support the fantasy, because Superman cannot “seem” weak, even if he is vulnerable on the inside. And the most interesting thing is that that physical strength also changed him. the psychology of paper: The stronger he became, the more natural the character’s calm authority came to him. Too “handsome”. The result was so extremely effective that it became a continuity problem: Reeve continued to gain muscle during filming and there came a point where It was not the same body of the first scenes. The production had to redo shots already filmed because the superman of one day did not fit with the Superman of weeks later, and the suit, designed for a “before”, began to behave like a shell that was too small. The ironic twist is that at first they wanted to put fake muscles under the uniform and, after the transformation, the opposite happened: They were able to remove the additions to the suit because they were no longer needed, and the film was left with what it had always needed from the beginning, a Superman with real muscle, without tricks or cardboard. The myth that remained. Over time, Reeve’s physique has been compared with the hypertrophied standards of today’s superheroes, but at the time it was quite an event: his change from “tall, skinny actor” to muscular icon It was part of Superman’s own story even before of the premiere. The important thing was not to compete with modern mountains of biceps, but to build an exact illusion: that this guy could be the most powerful on the planet and yet the most human when he looked at Lois … Read more

We Spaniards are stopping having Christmas trees because they don’t fit in our house. So there are already companies renting them

The year or the city doesn’t matter. At least in Spain, Christmas usually comes accompanied by a series of images that are repeated December after December, invariably: streets full of colored ledsbalconies in which they begin to appear papanoels and other Christmas decorations, shop windows in which gold, silver and reddish colors suddenly predominate… and living rooms in which trees full of tinsel and garlands sprout overnight. Year after year the same questions are also repeated: better natural or artificial tree? And above all… What the hell do we do with it after Epiphany, when it’s time to pick up the decorations? Where do we store it, if we already have the storage room all the way up? There are those who have seen In those doubts a promising business. Tree Earrings. There is no Christmas without decorations. And there is no Christmas decoration worth its salt without a good tree. It’s been like this all our lives, but just in case there were any doubts, cities like Vigo, Barcelona, Badalona either Madriddetermined to build gigantic trees in the heart of the urban area. Something similar happens in businesses, offices and homes. People demand trees (both artificial and natural), something that is felt in the nurseries and the big chains of decoration. As a reference, the National Christmas Tree Association (NCTA) estimates that each year they are sold in the US between 25 and 30 million of natural Christmas trees, which requires a huge plantation with hundreds of millions of copies distributed throughout the country. The dilemma, whether you choose real or fake fir trees, is… What to do with them later? A question, a business. There are those who have seen that question and the demand for Christmas trees as a business. After all… Why rack your brains choosing decorations, assembling them, disassembling them and then looking for a place to store them for months if we can pay a company to take care of everything? Or better yet, what if instead of buying the tree we rented it? Leasing trees may sound strange, but there comes a quick search on Google to find a few companies that operate in Spain and they dedicate precisely to that: to temporarily give up trees full of lights in exchange for a fee. The offer is wide and includes everything from small specimens to others of large size and size, for both indoor and outdoor spaces. But is it a business? Yes. The holidays may only last a few weeks, but if companies like Ximenezthe Córdoba company that has been in charge of setting up decorations in Vigo, Madrid, Barcelona or Milan, is that Christmas decorations can become a million dollar business. After all, it is not only families who demand decoration. Governments and companies of all kinds also do it, from businesses that do not have space to store decorations the rest of the year to hotels that need trees for their living rooms and hallways. In a warehouse in Madrid… One of the most popular Christmas tree rental companies in Spain is B&M, a family business with twenty years of experience that works from a warehouse in Tetuán, Madrid. Recently those responsible they explained to The Spanish Newspaper Every campaign, about 200 trees come out of there ready to decorate and that the company itself is in charge of collecting once the holidays are over. Their work involves several challenges, such as matching the taste of their clients and coordinating the logistics that require dismantling and removing 200 trees during the second week of January. “The pickup is intense because on the 9th everyone wants you to pick it up.” “Three, four hours at least”. The company also makes it clear that although it may seem like a simple task, preparing the ideal tree requires work. First they convey a proposal to the clients. Then they shape it. “A four or five meter tree is a job for five or six people, who have to spend at least three or four hours on it,” clarifies the signaturewhich explains, for example, that there are businesses that want trees with their corporate colors. How much do these services cost? In your website There are rates (with delivery and collection service included) ranging from 265 to 2,800 euros, without VAT. It all depends on the tree you want. They range from 1.5 to five meters. Are there more options? Yes. The demand for Christmas decoration is intense enough that it has encouraged other businesses, such as those that are committed to sustainability and offer a rent in pot. Your proposal? Instead of buying a plastic tree or taking a felled fir, rent one that you can place in your house alive, with its pot. Once in your living room you can decorate and take care of it and after Christmas the company will collect it to take it to a forest or to its nursery of origin.

There is a ‘good’ fat that hides a secret to aging better and being fit. It only remains to get the pill

Aging is inevitable, and with it it comes A progressive loss of physical capacity that causes it to be more difficult to walk or stand up. This makes Stay fit It becomes much more difficult and therefore the resistance begins to decline. But … what if this decline can be slow down? This is precisely what science is focused on. Fat as anti -aging. Researchers at the Rigers New Jersey Medical School They have discovered That a special type of adipose tissue, known as brown fat, could be the key not only for healthier old age, but also Improve physical performance. A study of great relevance, since it can open a new route in the anti -aging field. The team that has led this research has been able to identify an unusually powerful form of this ‘good fat’ in mice, which not only Increased his life expectancybut improved its exercise capacity by an impressive 30%. Now, the race has begun to be able to replicate these same effects in humans through a drug. Not all fat is bad. When we think of fat, the White fat or white adipose tissue. Its main function is to store excess calories in the form of triglycerides and is the one that can bother us aesthetically throughout our lives. Although in essence it is a large energy deposit. But, nevertheless, there is another type of fat that is much more interesting: brown fat or Brown adipose tissue. Unlike white, brown fat is specialized in burning calories to generate heat in a process called thermogenesis. This is possible thanks to the fact that their cells are full of mitochondria, which are the organelles that act as cellular power plants and that give it its characteristic brown color. In our life where we have more fatty fat in our body is when we are babies, since here it is crucial for Keep body temperature. But when we grow, the brown fat is lost until some cracks are around the neck and shoulders. But here the white fat is the one that dominates our body completely. One step further. Knowledge about brown fat already has a long journey in scientific literature. But it is now when this study goes further to point that it is linked to having a healthier longevity and with a much more appropriate physical exercise. How they knew it. To get to this conclusion, the researchers worked with a genetically modified mouse model to lack a protein called RGS14. The mice without this protein lived approximately 20% than their normal partners, and curiously the females lived more than the males in a pattern similar to that followed by humans. Even at the advanced ages, these mice avoided the typical signs of aging such as body atrophy, hair loss or the graying of the fur. But it does not stay here, since when submitting them to physical tests, the modified mice showed a 30% higher performance, both in distance traveled and in resistance. And all this because mice without RGS14 developed a dense and powerful brown fat than who expressed the protein correctly. The definitive test. To confirm that it was brown fat, and not another effect of genetic modification, scientists conducted a crucial experiment: transplanting the brown ‘supergras’ of mice without RGS14 to normal and healthy mice. The results were overwhelming. The mice that received this transplant improved their ability to exercise in just three days. On the other hand, when brown fat was transplanted from a normal mouse to another, an improvement was also observed, but much more and with eight weeks ahead to manifest its effects. Something that showed that the fat of the genetically modified mice was exceptionally powerful. Because? The mechanism seems to reside in an improvement in blood circulation. The indications suggest that brown fat promotes the creation of new blood cases in the muscles that improves the flow of blood and oxygen during exercise. The goal. Research suggests that this brown fat not only improves physical performance, but also protects against a series of ailments associated with age, such as obesity, diabetes, cardiovascular disorders and even cancer and Alzheimer’s. Vatner’s team is already working with collaborators to develop a drug that imitates the effects of this powerful brown fat, hoping to have a compound ready to be tested in approximately one year. But the idea is not only to increase life expectancy, but “healthy life expectancy.” That is, even if you live longer, these ‘extra’ years enjoy good physical and mental health. While we expect that future pill, there are techniques such as deliberate exposure to cold (the famous ice baths) that can naturally increase our brown fat levels. However, as Vatner points out, most people would prefer to take a pill to take an ice cream bath. Images | Tatiana Zanon In Xataka | Our brain has its own backup.

The US is dismantling the chips law. His blow will fit the semiconductor industry throughout the planet

Donald Trump is fulfilling what he anticipated both during the electoral campaign and after returning to the White House. The Chips Law Approved in July 2022 By the government of Joe Biden He has never liked him. Has made it very clear in statements such as this last January: “In the very close future we will impose tariffs on foreign production of computer chips, semiconductors and pharmaceutical products to return the manufacture of these essential goods to the US (…) went to Taiwan; now we want them to return. We do not want to give them billions of dollars in the ridiculous driver program. They already have billions of dollars.” Three months before, in October 2024, I had already charged ferocity against this program of the previous administration In Joe Rogan’s podcast: “We put millions of dollars on the table so that rich companies came, they borrow the money and build chip companies here. And they will not give us the best companies.” The Department of Commerce has seized 7,400 million destined for chips During the electoral campaign the possibility that Donald Trump dismantled the Chips program if he arrived at the government was on the table. A priori the money that has already been delivered will not be returned to the administration, but a part of the funds remains in the hands of the Department of Commerce, which is currently led by Howard Lutnick. And the dismantling has already begun. As we explained last Friday, the US government plans Reassign at least 2,000 million dollars coming from the heading for research and manufacturing integrated circuits within the Chips Law. If this measure thrives these funds will be used to finance projects dedicated to obtaining and the processing of critical minerals. At the moment China controls extractionthe processing and distribution chain of a good part of this crucial strategic resource for many industries, such as integrated circuits, telecommunications, batteries or electric car, among others. The government plans to reallow at least 2,000 million from the game for the investigation and manufacture of chips However, this is not all. And it is that the US Department of Commerce has seized a fund of 7.4 billion dollars that was managed by the National Center for the advance of semiconductor technology (Natcast), which is a private non -profit organization. This money comes from the Chips program and was intended for the research and development of new technologies for semiconductors. The Department of Commerce has justified this seizure arguing that the creation of Natcast by the Biden Administration was an attempt to “avoid clear legal restrictions that They prohibit government agencies to create corporations“In addition, Secretary Lutnick has declared that this organization was “a bribe fund that did nothing but fill the pockets of loyal to Biden with dollars from US taxpayers.” A priori we might think that this measure only affects the US, but nothing is further from reality. Its impact will be received by the global semiconductor industry. American research has made fundamental contributions to the global integrated circuit industry, so the cut of funds for this item in the Chips Law will be a perceptible effect in this sector. As a button shows: the extreme ultraviolet radiation source (UVE) that they use ASML photolithography equipment It was developed by Cymer in the US. If we stick to Natcast’s role in the current semiconductor research, it is important that we do not overlook that this organization is involved in the construction of the extreme ultraviolet light accelerator (UVE) of Albany (New York). And also in the tuning of an Chips Research and Development Center in Tempe (Arizona). The Commerce Department has not yet confirmed What will you do with the 7.4 billion dollars That he has seized, so the future of New York and Arizona research facilities is uncertain.

A laboratory has recreated the first molecule after the Big Bang. The result does not fit with our history of the universe

In the beginning, God created heavens and earth. And the earth was without order and empty. And the darkness covered the surface of the abyss, and the Spirit of God moved on the surface of the waters. Then God said: Be the light. And there was light. Go if there was light. A little context. Just after the Big Bang, the universe was an unimaginably dense and hot place. But as it expanded and cooled, the matter began to organize. First, protons and neutrons formed the nuclei of the lighter elements. Three hundred eighty thousand years later, temperatures fell enough for electrons to join these nuclei, forming the first neutral atoms: mainly hydrogen and helium. And it was then, in that cosmic childhood, when chemistry was born. The first molecule. The first chemical bond of the universe was the helium hydride ion (HEH+). A simple molecule formed by an atom of neutral helium and a hydrogen core; That is, a proton. For decades, his role in the birth of the first stars was subject to intense debates and theoretical simulations. Now, a team of researchers from the Max Planck Institute of Nuclear Physics in Germany has achieved recreate for the first time The reactions of this molecule in conditions similar to those of the primitive universe. The result has been a capital surprise that will force physicists to reconsider what they thought they knew about how the first lights lit. The first stars. After the formation of neutral atoms, the universe entered into A period known as the “dark age”. There were still no objects that emitted light, such as stars. For a star to be born, a gas cloud had to contract until enough density and temperature to start the nuclear fusion. But there is a problem: for the cloud to contract until that point due to gravity, it needed to dissipate heat. Below the 10,000 degrees Celsius, hydrogen atoms are not able to radiate that heat. This is where the molecules come into play. Helium hydride (heh+) can cool gas in a much more efficient way due to its strong dipole moment: it radiates heat emitting photons when rotating and vibrating. Something does not fit. Physicists believed that HEH+ had been a key cooling agent in the primitive universe. The problem was that HEH+ could also be destroyed by colliding with the omnipresent hydrogen atoms. Until now, the theoretical models predicted that the destruction reaction had slowed down drastically due to the very low temperatures of the primitive universe, but no one had verified it experimentally. The results of the experiment, published in the magazine Astronomy & AstrophysicsThey are completely unexpected. To the difference of all predictions, the reaction does not slow down at low temperatures. In fact, its speed remains almost constant. What physicists call a “reaction without barrier” occurs.

Intel will fit one of the toughest blows in its history. One directed directly to its chips factories

“These decisions are difficult, but they are essential to face the challenges we are already facing the company’s current financial situation. It is very painful.” These words They are part of the statement That Naga Chandrasekaran, the manufacturing vice president of Intel, sent the employees of this company last Saturday. In his concrete message that the Board of Directors is preparing A template reduction that will range between 15 and 20%as well as most of the cuts will arrive in July. The challenges a Those who currently face Intel They exceed the other challenges that he has faced during his more than half a century of history. The leadership that has sustained for decades in the manufacturing industry of integrated circuits is in the hands of The Taiwanese company TSMC since the mid -2000s. In addition, the stagnation during the last years of the PC market and the slowness with which Intel has participated in the industry of the industry of the artificial intelligence (AI) have placed it in a very compromised position. In July 2024, the company that at that time led Pat Gelsinger gave a tremendous batacazo in the stock market. Their actions fell 30% in a few days and stabilized in the value they had in 2011. In addition, Intel lost $ 1.6 billion During the second quarter of 2024 and its year -on -year income fell by 1%. These circumstances triggered a crisis that still persists today. This cut will have an inevitable impact on Intel factories Last August 2 Intel announced that was about to start a structural adjustment plan that pursued to reduce the costs of the company and increase its agility when adapting to the challenges that the market currently imposes. Its objective was to fire 15% of the workforce (more than 15,000 employees) and reduce costs by approximately 10,000 million dollars. Pat Gelsinger had declared shortly before Intel was inefficient because he had an excessively complex structure. It is still early to identify how this measure will affect the competitiveness and performance of Intel factories Not even Gelsinger himself “survived” this regeneration process. On December 2 This executive came out in a somewhat precipitated way of the company, whose course was uncertain until last March 18 Lip-bu took the reins of Intel. This veteran physicist and nuclear engineer He hastened to confirm that two of the pillars of its strategy would pursue reinforce the company’s position in the AI ​​market and reposition Intel as a leading company in the integrated circuit manufacturing industry. Shortly after his arrival It was leaked that lip-bu so He planned to launch a new cut of the Intel template in a clear attempt to reduce their operating expenses, among which personnel costs or marketing expenses are counted. The figure that the company shuffled on this occasion amounted to 20% of its workforce, which in practice implied to dispense with approximately 20,000 workers. These people join the more than 15,000 employees of which Intel has dispensed with during the last months of 2024. Now we know something else. From the statement that Naga Chandrasekaran has sent just four days ago to Intel employees it follows that during the next weeks they will be forced to leave their jobs Between 8,000 and 10,900 factor workers That has this company disseminated throughout the planet. However, presumably the most affected plant will be the largest of all: that of Oregon (USA). It is still early to identify how this measure will affect the competitiveness and performance of Intel factories, but its size invites us to anticipate that it will have a deep impact on the production infrastructure of this company.

How micro -redes fit into the energy puzzle

In recent years, Spain has turned the sun In his best ally for photovoltaic generation. However, the April 28 blackout has evidenced the lack of effective integration in the electricity network. Short. Until now, the first image that always accompanies renewables are batteries, but there is another network coupling system: micro -redes or micrographs. According to He explained Borja Santos, CEO of Full & Fast, for Europa Press, micro -redes are autonomous energy systems composed of a power converter and a battery system. These systems receive all energy inputs and outputs from different sources, such as structure, solar panels or even conventional electricity. Deeper. The micro -redes They operate through storage systems that allow accumulating the energy generated at times of low demand or high production. This stored energy can then be released at critical moments, guaranteeing system stability. This model not only provides supply security, but also offers economic opportunities by managing stored energy and releasing it when the market price is more favorable. When the energy zero arrived. In case of a main supply drop, the MICRORRED can continue to function independently, maintaining the continuity of the energy service for its users. In other words, micro -redes act as a “network within the network”, allowing communities, industries or rural areas to continue operating without interruptions, even if the national electrical system collapses, such as has detailed Borja Santos. In addition, he added that the blackout revealed the lack of systems capable of generating its own voltage and frequency reference. The micro-redes, on the contrary, can do so, thus preventing the systems from entering in a state of “stand-by” as happened in Spain. In other words, what gives you the micorred is self -sufficiency and the ability to continue operating and working uninterruptedly, there is light or not. A country with solar overcapacity. Spain has invested massively in solar parks, but, like has pointed out The former Minister of Public Administration, Jordi Sevilla, the electrical system has not adapted to this new reality. Seville has warned that “the generation points connected to the transport network have been multiplied, as well as its geographical distribution,” which has increased the complexity of managing the electrical system. In addition, he explained that the normative proposals presented by Red Electrica to regulate photovoltaic investors have been in the Ministry’s drawers for years, while the network still does not adapt to the new realities of the energy mix. However, the problem does not lies in generation capacity, but in the inability to manage it effectively. In this sense, Borja Santos has pointed out That “in Spain there is overcapacity of solar generation, but those solar parks confront a problem: they generate maximum energy when you least pay the market”, which reduces profitability for investors. The implementation. Despite the potential of the micrordes, their mass implementation in Spain faces several challenges. On the one hand, the current regulation does not sufficiently encourage the development of these systems, and the normative proposals that would allow renewables to help control the tension and reactive current of the network still sleep “the dream of the righteous”, According to the former minister. On the other hand, the Spanish electrical system It has been designed To manage synchronous energies, such as gas or nuclear, which generate their own frequency reference. Renewables, on the other hand, depend on electronic systems that do not offer this reference naturally, which increases the complexity of integrating large volumes of solar or wind energy without compromising its stability. For that reason, UNEF has pointed out the implementation of the procedure Operation 7.4 would allow renewables to control the tension and reactive current of the network, contributing to mitigate future blackouts. Forecasts. The April 28 blackout evidenced a problem in the management and storage capacity of the national electrical system. The micro -redes are presented as a solution thanks to their ability to operate independently and maintain the supply at critical moments.

This bridge built by China is so high that two Eiffel tower fit under it. And they have built it in just four years

We have been having bridges from prehistory. From that tree That someone would use to connect two sides to the majestic Roman bridges, humanity has evolved while doing the bridges he built. The more recent techniques They allow us to connect extremes that are separated by tens of kilometers, but Talk about bridges It is currently looking at China. They not only have The longest maritime bridgebut also the highest in the world. It is the Bridge of the Grand Canyon of Huajiang and the most surprising thing is not that under it two Eiffel Tower enter one over another, but that it has only taken four years to lift it. Necessary. The Gran Canyon of Huajiang is located in the province of Guizhou. It is an area that, traditionally, has been isolated from the rest of the area for a reason for weight: more than 90% of the territory is mountainous terrain that hinders communication. For centuries it did not have much importance for the rest of the empire, but China has been raising infrastructure (and also excavating) to demolish those geographical barriers. Puzzle. The objective of the government is to connect rural areas with urban centers and, in this case, you had to get the Liuzhi-Anlong highway to raffle the mountains to speed up transport times. The only way was through a bridge, and after an analysis period, in 2022 They started The construction of the great bridge. It was not going to be simple: it should not only be at a considerable height, but to have a length of almost three kilometers. And the problem was not so much to create the suspension bridge, but to raise the necessary materials. To do this, implemented Advanced technologies to raise steel beams by up to 215 tons of weight and, despite the difficulties in the field, the works have gone at a pone rhythm. To all fuse. That is what usually attracts the attention of these Chinese infrastructure that, weighing some exceptions such as half -building abandoned skyscraper For years, they are an example for the rest of the world. The works advance with speed and, if At the beginning of this year We already saw the two towers of 262 and 205 meters on both sides of the bridge, as well as the cables of 9,000 tons each, now we observe that they have already built the section that joins the ends. The length Total of the bridge is 2,890 meters and the main section, which is among the towers, has a length of 1,420 meters that positions it not only as the highest bridge in the world (it is 625 meters from the ground, reaching the end of the towers at 776 meters), but as the longest hanging section built in the mountainous area. The comparison with the height of the Eiffel Tower is interesting, but almost two Empire State Building would also enter. The technology used in construction is also interesting. For example, when the concrete pour, Guizhou Bridge Group builders devised a system of pipes that pump cold or hot water depending on the outer temperature to ensure that fresh concrete dried in the best possible conditions to avoid cracks. And, to guarantee maintenance, the cables have sensors that measure vibrations or wind intensity to offer reports on the state of the hanging section. Impact. In January of this year, it was reported that 75% of the project had been completed, but in recent months we have seen how they have advanced so much that it is practically only missing and installing the security elements. The idea is to open at some point in June this year and, once open, will allow Crossing the canyon in just a couple of minutes when before it was something for more than an hour. But beyond all this, the most impressive thing is that they have been able to build an infrastructure in a very complicated place and condense 439,000 m³ of concrete and 49,000 tons of steel in just four years. And the cost? In theory, 280 million dollars that are difficult to estimate whether they will recover by joining rural areas, but as infrastructure and demonstration of strength, the Huajiang Grand Canyon bridge is imposing. And will remove the record from the highest bridge Lege’s, also in China.
