Data centers for AI are an energy hole. Jeff Bezos’s solution: Build them in space

by

In the next two decades we will see data centers at Gigavatio scale orbiting the Earth. Or at least that is the prediction that has launched The founder of Amazon and Blue Origin, Jeff Bezos. He said it during his speech at the Italian Tech Week in Turin, where he was able to establish conversation with John Elkann, president of Ferrari and Stellantis. Bezos’s proposal. Space data centers would take advantage of solar energy 24 hours a day, cloudless, rain or night cycles that interrupt the supply. According to Bezosthese “giant training clusters” of artificial intelligence would be more efficient and, eventually, more economical than terrestrial facilities. “We can exceed the cost of land data centers in space in the coming decades,” he said. Why now talks about this. The infrastructure demand for AI is becoming a large hole for the planet. Current data centers consume massive amounts of electricity and water to cool its servers, a problem that is aggravated with each new artificial intelligence model. Given this pressure, large technology explore alternatives: from Locate them in ships o Nordic countries until sink into the ocean. And of course, if we have capacity problems on Earth, some technological ones already think about taking the letter to send them to space. The technical advantages. In space, temperatures range between -120 ° C under direct sunlight and -270 ° C in shadow, which would greatly simplify equipment cooling. Constant solar energy would eliminate dependence on land electrical networks. Bezos places this development as’Natural evolution‘of a process that has already begun with weather and communications satellites. “The next step will be the data centers and then other types of manufacturing,” he explained. The real challenges. As they point out from Tom’s hardwarebuilding a spatial data center of a Gigavatio would require solar panels that would cover between 2.4 and 3.3 million square meters, with an estimated weight of 9,000 to 11,250 metric tons only in photovoltaic material. Transporting all that equipment to space would cost between $ 13,700 and 25,000 million with current technology, needing more than 150 launches. To this is added the difficulty of maintenance, updates and the inherent risk of space releases. Parallelism with AI. Bezos compared The current moment of artificial intelligence With the bubble Puntocom of the early 2000s. “We should be extremely optimistic about the social and beneficial consequences of AI,” he said, although he warned of the possibility of speculative bubbles. His message: Do not confuse possible excesses of the market with the reality of technological advances, whose benefits consider that “they will spread widely and reach everywhere.” When It will be done reality?. Bezos places the temporary horizon “in more than 10 years, but no more than 20”. Today, the project is commercially unfeasible, but its vision starts from the premise that the launch costs will continue to go down and the technology will mature. It remains to be seen, after two decades, part of our digital infrastructure is in orbit, beyond the existing one.

In the nineteenth century, Spain made the strange decision to build its ways in Iberian width. Now they will be a gift for Renfe in Galicia

by

Renfe can breathe calm. The company has a huge business in the Galician corridor. The volume of travelers Between Madrid and Galicia he has shot to the point that airlines are retreating. Time savings since high speed arrives is such that many are choosing to pass to the train due to pure comfort or time flexibility. The Galician corridor is part of the next package of liberalization of the roads, next to the trains with destination Asturias, Cantabria, Cádiz and Huelva. It will not be, at least, until 2028 when the competition is palpable on the tracks because Adif is not complying with the deadlines planned. But Madrid-Galicia has another peculiarity. It is very likely that in 2028 we will see competition on their ways. To find the reason we have to travel to the nineteenth century. The particular Spanish railroad Each new technology arrives with a good rosary of standards of all kinds. It has happened with electric cars and passed with electricity itself. Also with measurement standards or, as in this case, train tracks. The railroad had started in the early nineteenth century. Although the steam machine was already born in the 18th century, it was not until 1804 when Richard Trevithick built A prototype in which the concept applied to transport. The steam locomotive was born. That one of those huge irons with wheels will pull a kind of drawers and could move the goods faster than they had done seemed like a great idea. So great that it soon caught and in 1830 the first train line was opened with passengers. They were the famous 50 kilometers that separated Liverpool from Manchester whose first trip headed George Stephensonwho was the ideologist of the construction of those first route. Those first trains circulated through some roads of 1,422 millimeters, 4 feet and 8 inches. Shortly after, those same ways widen half inch until reaching the famous 1,435 mm. Then they did not know but they had just adopted the “international width”, which is mounted in most trains in the world. Those measures also served to establish Two categories: narrow path (below those 1,435 mm) and wide via (above). The good results of the first trains made the railroad make the leap to continental Europe and the United States. But, like everything in this life, there were those who thought the system could be improved and that it was worth trying. That person was Isambard Kingdom Brunelan excellent British engineer who would create the Great Railroad of the West, joining London with the southwest, western England and much of Wales. Brunel thought that the higher the width of roads, faster speed could reach a train because the greater the stability achieved. Thus, it extended the track width up to 2,140 mm. Then a war of standards began that ended up resolving the Commission of Railroad Widths in favor of Stenphenson and its width of 1,435 mm. It was 1845. In Spain, at that time, we were engaged in the same fight. Railroad yes, but … how? That doubt was the one that set fire in the middle of the 19th century. Observing the good results that were being achieved outside our borders, the Government began to receive requests for the granting of licenses that allowed them to exploit the roads. Aware that it was necessary to harmonize the matter, they consulted a commission of engineers led by Juan Subercase, number one in the Corps of Engineers, acting president of the Advisory Board and director of the School of Engineers since 1837. He was helped Calixto Santa Cruz, number one of his promotion of 1839, and José Subercase, who in addition to his son was also the number one in his promotion the following year, 1840. Together they drafted the report 17.10.1844, on the Madrid Railroad to Cádiz, which recommended to reject a concession to build a railroad from Madrid to Cádiz. This concession was requested by the French engineer Juqueau Galbrun, which was certainly ironic over the years. Explains J. Moreno Fernández in a document in which the whole story of that controversial decision tells that none of the mentioned engineers had left the country and known firsthand how the railroads were abroad. That, perhaps, was one of the reasons why it was omitted that France had opted for international road width. And it is that Subercase was a firm defender of a width of six feet Castilians. The 1,672 millimeters that would end up receiving the name of “Iberian Width”. The defense is that a higher track width forced to use more powerful locomotives. In those days they thought they could increase vaporization with a wider boiler and that this was essential to, in a mountainous country like Spain, to have sufficient power to move the train. They also defended that a higher track width allowed a more stable step per curve but the truth is that time showed that neither one thing nor the other were key. The international width has been versed enough to be used in mountainous areas and the largest boilers in the trains had the problem of increasing the weight so the gain was diluted. In the government they thought that Subarcase motivations They were correct and they didn’t care that in the neighboring country they bet on a narrower track width. To import, they did not care that our other neighbor, Portugal, also promoted their railroads with the international width. In 1844, it was finally decided that the Spanish measure of the six Spanish feet was the one that should be protagonist for its orographic peculiarities. However, that did not condition the government that gave the approval to two routes built on that international width that was quickly imposing. Portugal pressed to have a railway exit to France that Spain ignored. And that created an urban legend that remains until today First in a line between Barcelona and Mataró, projected from the beginning with that exceptional width for the Spaniards … Read more

Build the first closed cycle nuclear reactor

by

Vladimir Putin has announced what he calls the “first nuclear energy system in the world with a closed fuel cycle”, a technology that promises to reuse up to 95% of nuclear fuel. If it materializes by 2030, as stated by the Russian president, Russia would dodge two of the greatest challenges of current nuclear centrals: the Radioactive waste management and the possible exhaustion of uranium reserves. Uranium? What do you want that. In the Moscow Global Atomic Forum, and before the presence of figures such as Rafael Grossi, director of the OIEA, Putin described the Russian reactor of closed cycle as a “truly revolutionary development” that, in his words, “will eliminate the problem of uranium supply.” The centerpiece of the ambitious Poryv project (“advance” in Russian) is a rapid reactor refrigerated by lead called Brest -od-300, which is being Building in Severska city in the Siberian region of Tomsk. In the same complex, called Odek, Russia will also build the modules for the spongery and reprocessing of the irradiated fuel. 95% recoverable. In addition to using molten lead instead of water as refrigerant, the Brest-O-300 reactor is designed to operate with uranium-reputony nitruro as fuel. It is its in situ integration with the sponge and reprocessing modules that will allow closing the nuclear fuel cycle. According to official statements, this system It will allow 95% of the spent fuel to reusea technically consistent figure with the external reprocess processes, where most of the fuel used (uranium and plutonium) ends up being recovered. The remaining 3-5% corresponds to fission products and minor actinids, which remain high radioactivity residues. It is not a new technology. Countries like France and Russia itself Nuclear fuel already reproces at an industrial scale. And Japan intends to join the club with the Rokkash Plant. However, the Russian project is a pioneer in its attempt to create a fully integrated complex where a fast reactor operates in symbiosis with its own fuel manufacturing and recycling facilities in the same place. If Russia meets its deadlines, you could have The first complex of this type in operation. And to support him, he has established an International Research Center in the Uliánovsk region (the MBIR International Research Center in Dimitrovgragra), inviting scientists around the world to collaborate in what Putin has called a “new era in nuclear energy.” But is uranium running out? Putin’s justification for this strong investment is a future with uranium shortage. During his speech, he cited OECD estimates that suggested a possible exhaustion of uranium resources by 2090, or even before: as soon as in the 2060s. However, the “Red Book” of the OEA does not speak of an exhaustion of uranium, but of An increase in demandwhich could produce tensions in the supply between 2080 and 2110 if significant investments are not made before for the opening of new mines. Russia’s plan It is a strategic bet. If you achieve the closed cycle reactor for the 2030s, we could witness a new way of understanding nuclear energy, and a world with limited resources in which Russia has managed to outdo the rest.

To build an “artificial sun” we need to be able to move the weight of ten elephants with millimeter precision. This is what China has just done

by

In Chinese mythology, Kuafu was a giant who challenged the gods when trying to catch the sun to give light and heat to their people. Centuries later, China re -pursues that same ambition, but now with avant -garde science: to create a “Artificial sun” that provides clean and unlimited energy. And in that way, the engineers have just presented a new protagonist worthy of legend: a colossal robot. The arm for fusion. The Asian giant has developed a remote manipulation platform for future fusion reactors. It is a system with three robotic arms, whose main manipulator can raise up to 60 tons – the weight of ten African elephants – with a millimeter accuracy, According to South China Morning Post. Meanwhile, the two secondary arms stand out for even more extreme precision: ± 0.01 millimeters, which makes it the most advanced remote management system in the field of fusion. Closer to the “artificial sun.” The objective of this whole project is to achieve stable nuclear fusion, that almost inexhaustible energy that mimics the process that occurs in the sun’s core. In fact, China has been breaking records for years in its East experimental reactor, which this year has achieved Maintain a confined plasma for 1,066 seconds, a world record that exceeds 403 seconds Realized in 2023. But for this energy to become commercial, it is necessary to resolve a major challenge: maintenance. The internal components of a reactor, such as coating or the diving, are constantly damaged by heat, radiation and magnetic fields. And this is where this new robot comes into play: no human being could work in these extreme conditions. The in -depth project. The robot is part of the craft (Comprehensive Research Facity for Fusion Technology), an installation in Hefei, Anhui, nicknamed “Kuafu” in honor of the mythical giant. More than 300 scientists and engineers participate in this project, According to SCMPunder the supervision of the Institute of Plasma Physics of the Chinese Academy of Sciences. “We have developed a machine capable of meeting extremely demanding requirements by overcoming obstacles in materials, sensors and control,” explained Pan HongtaoInstitute researcher. The idea is to use craft as a test bank to develop and validate key fusion technologies, including those that will be applied in the future Chinese experimental fusion reactor (CFETR) and in the International Iter project In France. Ready to go into action? For now, we are not talking about an operational robot in a reactor, but of an experimental platform. According to China Dailythe system has already exceeded the evaluation of experts and will serve as an engineering verification platform to ensure that, when reactors enter into operation, remote maintenance is safe and precise. Craft, where it is housed, plans to be completed in the late 2025. Beyond fusion. Although the immediate objective is to maintain fusion reactors, technology is not limited to that field. According to CGTNthe advances achieved in this robot could also be applied in inspection of nuclear plants, aerospace industry, operations with heavy machinery or even emergency rescues. A global career for the artificial sun. The Kuafu robot does not arise in a vacuum. Other countries also develop remote maintenance systems, although with much lower capabilities. The most advanced arm of Mitsubishi Heavy Industries (Japan) supports only 2 tons. In contrast, the Chinese robot can manipulate 30 times higher loads. At the international level, the Iter project in France – in which 35 countries participate – will have a system Able to handle up to 45 tons. The new Chinese system already exceeds it in load capacity, although both remain development platforms rather than operating systems. The road map is clear but slow: Chinese experts They calculate that they are still 30 to 50 years to see commercial fusion reactors. And the European Union, with its Eurofusion projectdoes not expect to start testing with plasma until the end of this year. Forecasts The Chinese commitment to nuclear fusion advances with firm steps. The development of a robot capable of lifting 60 tons with surgical precision is not a simple engineering achievement: it is an essential piece for someday fusion reactors to maintain and function stable. Humanity He has been trying to replicate the energy of the sun on earth. With advances like this, China shows that it is determined to be the protagonist in that race. Decades may be missing to see fusion plants in operation, but every step we bring us a little more to that utopia to capture the sun.

The Spanish rail giant had planned to build a lightwail between Jerusalem and the West Bank. Now has a problem

by

The Basque CAF It is found In the international view for its participation in the Jerusalem Railway Project, which connects Israeli settlements considered illegal by the United Nations. The pressure on the company has intensified after appearing cited in An official report of the UN on companies that benefit from the occupation. A dispute project. CAF has been part of a consortium with the Israeli Shapir since 2019 to build and expand the red and green lines of the Light Jerusalem Rail. The project, valued at 1.8 billion euros, includes 27 kilometers of new roads and 50 stations that connect settlements in the West Jerusalem. The Basque company would take more than 500 million euros for construction and equipment, in addition to its participation in management for 15 to 25 years. Why is it problematic. The UN Special Rapporteur, Francesca Albanese, has included to CAF in its report “of the economy of occupation to the economy of the genocide”, presented before the Human Rights Council. According to the document, these infrastructure “contribute to the maintenance and consolidation of illegal settlements” and connect the colonies with Israel “while excluding and segregating the Palestinians.” The Human Rights Council itself declared the project illegal in 2016 and 2017. The pressure intensifies. Amnesty International has been asking CA for years to leave the project. “CAF cannot continue looking the other way and not meet international recommendations,” affirms Esteban Beltrán, director of the NGO in Spain. The organization also claims the Spanish government and the Basque Government, a shareholder of the company, to evaluate the CAF links with “the illegal behavior of Israel.” Others are retiring. The case It is not isolated. In 2024, the Catalan Comsa withdrew from the consortium that had won the construction of the blue line of the Jerusalem tram. The Basque Acerera Sidenor also announced that it will stop serving steel to Israeli companies. International funds such as the Norwegian sovereign have retired their participations from Shapir, a partner of CAF, and the manager Storeband excluded CAF from his portfolio for his participation in the project. CAF’s response. The company maintains in its sustainability reports that “no violation of human rights has been detected” derived from their participation and describes the territories as “object of political controversy.” However, for international organizations, CAF is obviating the resolutions of the UN Security Council, the European Union and the International Court of Justice on the illegality of settlements. Between the lines. The project places CAF at a crossroads between commercial interests and international pressure. Your shareholders include to the Basque Government, Kutxabank, the Matrix of the Mayoral Textile and the workers themselves with 25% of the shares. Meanwhile, the geopolitical context has hardened after the attacks of October 7 and the Israeli response in Gaza, increasing international scrutiny over any company linked to occupied territories.

United Kingdom will be just the first client. Spain raises a colossus in Galicia to build war ships like churros

by

While Spain does not count With f-35 fighterssoon he will do it with what will be a source of pride for the nation: The Bonifaz frigatefirst of the F110 class, whose launch took place in the navantia shipyards in Ferrol. In fact, Navantia has received a commission that will place her in the world showcase as a reference construction: United Kingdom has asked her to do her Your next frigate. In the background: a plan to become the elite of the sector. A naval milestone from Spain. Navantia is carrying out in Ferrol the largest investment of the last hundred years in a shipyard in Spain: the creation of the Digital Block Factory (FDB) conceived to place military naval construction in the world technological avant -garde. With a budget of 110 million eurosan area of ​​45,000 square meters, 500 meters in length and 90 wide, the plant will double the productive capacity of the Galician shipyard and mark the final step towards the model of shipyard 4.0where automation, artificial intelligence and robotization will be protagonists. The day. Its inauguration is scheduled for the First quarter of 2026after a construction process that began in March 2024 and has included the creation of a digital twin to monitor in real time the progress of the works, control cost deviations and anticipate failures. Unpublished productive capacity. The new factory will allow Navantia to manufacture in Only one year the blocks equivalent to a air holder such as Juan Carlos Itwo F-18 frigatesfour European corvettes EPCfour maritime action ships (BAM) or up to two combat supply ships (BAC), in addition to logistical support ships such as the FSS that already produces For the Royal Navy. In practical terms, the plant may generate simultaneously The blocks of two frigates, with a production cadence of one section every ten days (about 26 per year), which will reduce construction deadlines by 20-25%. In the case of the F-110, about 85% From the structure of each unit it will be manufactured in the FDB, while the singular blocks (such as the dome of the sonar or the multimission mast) will continue to be built in the traditional workshops. This scheme will simultaneously add the commitments to the Spanish Navy and the eventual Export contractsa strategic aspiration in the current context of International Rearme, where the armed demands to have their ships in the shortest possible time. Automation, AI and Robotics. The factory has been designed under an optimized workflow scheme, divided into three major areas: steels, prearmament and flip. In the first they will be installed Robotized welding lines Equipped with hybrid laser technology, guaranteeing higher structural dimensional precision and robustness. In the prearmament phase, the subblocks will be transferred autonomously by vehicles not manned with IoT sensors, and robots will be integrated for welding, manipulation and palletization that will work collaboratively with the operators. Finally, in the voltage zone, the blocks will be assembled with subcomponents previously manufactured in an automated assembly system that combines speed, flexibility and reliability. The whole process will be supported by a system of Complete digital traceability: Each piece will generate information associated with its digital twin, which will automatically readjust the following phases and detect real -time deviations using smart cameras connected to 3D models. The Innovation and Robotics Center. Navantia digital transformation is not limited to the plant itself. He Innovation and Robotics Center (CIR), directly linked to the factory, acts as technological nucleus where the latest innovations in automation, automatic inspection, advanced welding and dimensional control are tested and validated. The CIR not only develops solutions applicable to immediate production, but also works as Training and Transfer Space of knowledge, ensuring that advances are quickly integrated into productive processes. The ecosystem, reinforced With collaborations With the University of La Coruña and with specialized consultants, it guarantees, a priori, that the Ferrolano shipyard remains on the border of naval innovation. Labor impact. From the company it has been ensured that, despite the high level of automation, the factory will not involve a template reduction. On the contrary, it will maintain a volume of Between 270 and 400 workers In turn, including both direct employees of Navantia and personnel from auxiliary companies. In each turn they will operate Between 300 and 325 peopleconfirming that robotization is raised as a tool for support to human capital and not as a substitute. The combination of specialized manual labor and intelligent systems ensures that flexibility is maintained to meet specific demands of each naval program. Reference at the military plane. Once finished, the FERROL FDB It will not have equivalent in the world of military construction. The only comparable reference is the Alemán Meyer Werft Shipyarddedicated to luxury cruises and has been gradually applying automated systems for fifteen years. Navantia, however, will be the first company to move this industrial logic War shipswhich, according to the company, will allow you to offer a competitive, sustainable and higher quality product in a sector where the speed of delivery is practically a strategic requirement. In addition, the possibility of producing blocks to Other international shipyardsexpanding his role as a key actor in the global naval supply chain. New era in the estuary. If you want also, with this bet, Navantia aims to turn Ferrol into a World Reference Pole For military naval construction, combining tradition and modernity in a project that represents a before and after in Spanish industrial history. As Rafael Morgade underlinedresponsible for the digital transformation of the company, it is an authentic “new era” in which the Galician shipyard will go from a disorderly growth accumulated in a century to a concentrated, efficient and technologically advanced model. In a marked geopolitical context For the rearmethis megafactoría not only reinforces the capacities of the Spanish Navy, but also positions Navantia as a industrial partner in the elite of the international defense market.

Build it at home

Getting with a yacht is usually a common whim among billionaires. Entrepreneurs such as Jeff Bezos and Mark Zuckerberg have not hesitated to spend part of their fortune to navigate different parts of the world with comforts, style and, above all, luxury. The first commissioned the construction of ‘Koru‘To the Dutch firm Oceanco, the second decided to save this step and He bought ‘launchpad’ a Russian oligarch. An American named Clyde Stirs followed a completely different path to have the yacht he wanted, A catamaran of 27.86 meters of length and manga of 12.41 meters, equipped to receive a dozen guests. Stirs counts in a video posted on YouTube That he was not a millionaire, but that he decided to channel all the resources he had at his disposal, in combination with a great determination, to build the yacht of his dreams. To build personalized vehicles to build their own yacht Stires was born in Missouri, although at the age of 12 he moved to California with his family. Since childhood he spent a lot of time with his father, who taught him to use different Cutting tools. With this knowledge as a base, he began to learn how to fix and build everyday objects such as toys. A long time later, in the 1970s, he found inspiration in the vehicle manufacturer Ed “big Daddy” Roth. After that, it began to build motorcycles whose designs conquered stars such as Elvis Presley and Johnny Graham. His passion for what he did was only increasing. Years later he was transforming a two -story bus into a caravan. He had previously bought his first ship in Taiwan, and decided that “she wanted to return to the water”, so he got rid of almost everything he had to start the project of his life, the construction of a yacht. The vehicles that manufactured Clyde Stires Stirs Account that Analyzed each part of the project before starting. Since I did not have enough economic resources, it could not afford to build the ship in a shipyard. The costs of doing so would simply be unattainable. Nor could he do it anywhere in the United States, since climatic conditions They could accelerate the deterioration of the ship under construction. So he decided to move to an ideal place to start the project. The caravan project He was in California, so he looked for a house in Perris, an old railway city characterized by its dry and sunny climate. After making several sketches, calculations and versions at a reduced scale, he got down to work in 1987. In the video we can see how the ship is gaining size with time. This undoubtedly caught the attention of the people of the place, as someone in the YouTube comment below. The “skeleton” of the yacht “He lived in Canyon Lake and passed in front of this every day on his way to work, he was very close to Highway 74. Suddenly, this huge ship began to appear, getting bigger every day. It was amazing to see it. I had to stop and ask what was happening with that ship. He was always working on construction. He was very kind and told me that he was building a ship to turn the world around. So what you asked was: how will this ship get to the ocean? The construction of the ship forced Stirs to improve all his techniques. This included from the welding for the rolling process to the installation of the wiring, the hydraulic system and the engines. Stirs took years to complete the cover coating, install all the equipment and paint the ship. Once it was finished, it was found before the difficult task of taking it to the sea, and the only alternative was to cut it and transfer it into pieces. The ship, called Kaleidoscope, was rearmed and thrown in 1994. That milestone for the project was only the beginning of a series of surprising episodes that would arrive years later. The American says that his ship was “stolen by a cartel”When he was in Puerto Vallarta, Mexico. Although after much effort, the authorities managed to recover the ship, the process of returning it to the United States was so complex that it decided to sell it. The years have passed and the yacht that once was from Stirs has sail again. At present it is part of the fleet of a boat rental company. Kaleidoscope is presented as a yacht with “all the comforts for the most luxurious navigation experience.” Its new owners also call it “Limuse of the Sea” and use it for private excursions or events celebrations.

We are running out of a key material to build roads and homes. And the guilt has the war in Ukraine

by

In the middle of the month of May a photo seemed to have sneaked between the “normality” of some remote roads from Teruel. The constant coming and going of loaded trucks up to clay He had the answer to thousands of kilometers, in the epicenter of the war in Ukraine. The shortage of the material because of the conflict had found a solution in southern Europe. But now it is, perhaps, more dangerous. We are running out of TNT. From the boom to the agency. I told it a few hours ago The New York Times. For more than a century, Trinitrotoluene (TNT) was a pillar of the American military and civil industry, with millions of tons produced for The two world wars and the second half of the twentieth century. Cheap and abundant (it cost just 50 cents per pound), it became key input for projectiles, pumps and the construction of roads, infrastructure and homes. The problem? That its production generated highly toxic waste, which led to the closing of the last national plant In the eighties. Since then, Washington became dependent on foreign suppliers, mainly in China, Russia, Poland and Ukraine, which assumed the environmental costs of their manufacture. The impact of war. The Russian invasion in 2022 transformed that scheme. The United States stopped recycling explosives of obsolete arsenals, by deciding allocate your production to kyiv. At the same time, Russia and China They cut Exports to the West, leaving the American industry without access to its usual sources. Thus, the European conflict triggered a World TNT scarcity with direct consequences for arms production and, very important, also for civil sectors such as mining and construction. Effects. The lack of TNT Threat with slowing down Infrastructure projects, from roads and bridges to the supply of cement and basic materials. He underlined the Times that the usual procedure in quarries (where minimal loads of TNT detonate ammonium nitrate mixtures with other compounds) has been affected by the reduction of supplies. The use of drones, 3D scanners and digital calculations allows more precise and safe explosions, capable of moving More than 100,000 tons of rock in a single shot, but without TNT the processes lose efficacy, which raises costs and threatens the availability of raw materials. The United States response. Given the shortage, Congress approved the construction of a new TNT plant in Kentucky, with a Budget of 435 million of dollars. It is planned to start operating in 2028, but, and very important, it will only produce for military use, without supplying the civil sector. No doubt, this reflects a clear priority: ensure the autonomy of the military-industrial complex against external dependence, although leaving without immediate solution the problem of extractive and construction industries. In parallel, the pentagon works in Diversify suppliers and increase the internal production of other explosives and propellant. Alternatives and scenarios. At present, the industry seeks substitutes such as The Petn (Tetranitrate Pentaeritritol), which is already manufactured in three US facilities, although its capacity is limited and it is not clear if it can be climbed quickly. Meanwhile, the country’s army has given signs of having assured Additional TNT sources out of Poland, although Without revealing details. In any case, the situation raises a strategic dilemma: the dependence on obsolete material but irreplaceable in many processes, whose absence threatens both the war capacity and the stability of basic sectors of the economy. TNT’s scarcity exposes, one more timehow a distant war can disrupt critical supply chains and force industrial powers to rethink their energy, technological and military security.

Before putting in front of OpenAi and lead the Chatgpt development To transform forever The world as we know itSam Altman spent his time to guide entrepreneurs and startups such as Reddit, Airbnb or Spotify on his way to success from the incubator and combinator he directed. During his stage as a mentor, Altman learned important lessons on how to cement a long -term successful professional career. The current CEO of Openai, wrote In your personal blog Some of those lessons to get a solid professional career. 1. Who does not risk, does not win Altman believes that most people tend to overestimate the risk and underestimate the reward. It is true that it is not always easy to assume risks, especially when you do not have enough experience or knowledge. However, the millionaire recommends Start taking calculated risksespecially at the beginning of the professional career, to learn to face them, and lose their fear of taking risky paths as progress is being made in the professional career. Especially at that initial stage of the races, Altman ensures that rewards tend to be much greater than losses. Successful entrepreneurs like Bernard Arnault They have assumed that mistakes are going to be madebut it is important to learn from them and not repeat them again in the future. Avoiding them is not always possible, so it is convenient to learn from veterans like Bill Gates and prepare for the worst and best scenario possible. 2. Constancy and optimism Sam Altman quotes Airbnb as a record reference. “They managed to survive enough time for luck to accompany them.” Maintain an optimistic attitude and determined to achieve the objectives setallows to stay in the line enough time to arise the necessary opportunities to achieve it.

Create and keep your pits It is not that Altman recommends burying himself on earth and digsing a ditch around. The theory of the tarry, widely used by Warren Buffettcreate an analogy between the strategic advantages that companies or people have surrounded by medieval strengths. The larger and deep the pits of these strengths, the more difficult the enemy turned out to reach the walls and knock them down. Based on professional or business, pits are your advantages, skills, knowledge, or any other difference that gives you some type of advantage over other employees, companies or competition in general. Creating and maintaining these pits in time makes the person or company more valuable and essential. “If you do the same as everyone else, it will not be difficult to compete with you,” says Sam Altman in his recommendations for success. 4.

A solid contact network is not achieved by keeping someone’s number on the agenda to call him when something is needed, but on the contrary.

Italy is going to build the suspension bridge with the largest opening in the world. And they will load it to NATO’s budgets

by

The megaconstructions are the order of the day. We find each other Colossal projectssome that They make us crack an eyebrow thinking If necessary. However, few can boast of being the culmination of a work of centuries, or even millennia. Italy is close to getting it when approved A huge bridge that connect the continent with Sicily: the Messina bridge. The turn is that they have described it as something key to the NATO. So that? So that the bridge budget is included in the percentage of military spending that Italy must contribute. Historical dream. Sicily is a complicated territory. Isolated from the continent, it remains Italy and, although they have a very strong identity feelingthat isolation has led to some problems and difficulties throughout history. In it Roman empire I know proposed Unite the territory through the Strait of Messina with a peculiar plan: connect Calabria and Sicily using barges and barrels. It was ruled out for obvious reasons such as intense maritime traffic or its technical unfeasibility. In the Middle Ages, Charlemagne too study take actions to unite the territory and, in 1866, firmer plans were drawn to build a viaduct, but they were also discarded when considering that A tunnel would be more suitable. In whatever, it also ended in nothing and, during the following decades, the project of the bridge in the Strait was changing hands without success, maintaining the connection with the peninsula by ferry. Colossal. Throughout. Everything changed in 2023, when the new Giorgia Meloni government resurrected the plan. Contemplating an investment of more than 13,000 million euros, the bridge would mark a turning point in Italian, European and world architecture, depending on who we ask. The length will be about 3.7 kilometers with twin towers of 399 meters on both banks, a height of 72 meters above sea level so that large boats and capacity can pass and capacity to move A large number of vehicles. The three lanes in the direction offer a capacity for 6,000 vehicles per hour, and their two railways would allow a cadence of 200 trains per day. It is a transport barbarity to connect Sicily, but the only thing about this bridge will be the central opening: 3,300 meters that would set a new world record for a suspended vain. Necessary. The start of the works is scheduled for this same 2025 and its estimated completion by 2032. As we say, after many comings and goings, the project is already officially underwayas the Minister of Transportation and Infrastructure of Italy, Matteo Salvini, advertisement Last Wednesday. Finally, the cost will be 13,500 million euros and, as we read in New York TimesItalian minister and vice president, he is “absolutely proud of work.” Stating that “it will be an unprecedented public works in the world.” The justification of the bridge, as we read in Financial Timescomes from the side of the revitalization of Sicily. With this volume moved from the continent, the economy of one of the poorest regions of Italy can be promoted, where unemployment practically double The national rate: 13% compared to 6.5% of the rest of the country. But … necessary? The question is why, if a bridge between both territories was so important, something had been done. And, above all, why firm projects such as 2011 threw himself by land, arguing concerns about his price, about 5,000 million euros at that time and, in addition, about his real need. And it wasn’t the first time: Silvio Berlusconi He already proposed This project in 2005 for about 3.9 billion euros. Criticism. Many. There are few detractors of the bridge. This “unprecedented work in the world” faces opposition, environmentalists and even nature itself. The opposition, as New York Times states, considers that it is “an economic and social catastrophe” by diverting funds from other projects more necessary to build “a cathedral in the desert.” The animalists lo consider A disaster for local flora and fauna, as well as for a bird’s migration route. And when we say he has against nature, it is because those critics too comment that the area is prone to earthquakes that could make the bridge collapse. Even the ‘thing nostra’, the Sicilian mafia, said Be against the bridge in 2023. It has a trick. If you have so much against, if it is not clear that you will revitalize Sicily after a mastodontic investment, why do you go ahead with the project? During the NATO summit in June, Meloni declared that, due to the convulsive moment that is lived in several parts of the world, “there are many threats and hostile actors operating on the southern flank of the Atlantic Alliance.” In addition, he commented that “Russia projects more and more His presence in the Mediterranean” And this bridge would be a key piece, according to the Italian government, “in the context of NATO defense and security, facilitating the movement of the Italian and international armed forces in a context in which the Mediterranean is a geopolitically sensitive area.” And the trick? Well, like other NATO allies, Italy has beenOppromeded to increase its annual expenditure in defense Up to 5% of its GDP during the next decade, including 1.5% for strategic infrastructure. If the bridge is 13,500 million euros and include it in their proposals for “strategic infrastructure”, they would already be hitting a good bite to that 5% They must invest. Instead of armament or other elements, in a new bridge. Germany goes behind. “The Mestina Strait Bridge constitutes a fundamental infrastructure in relation to military mobility, taking into account the presence of important NATO bases in southern Italy,” they said in a report prepared last April, but Italy seems to be the only ones that will try to ‘put’ a renewal of infrastructure in that 5% of NATO. Germany, in a recent reporthas included in these defense budgets other 1 billion euros for the maintenance of ‘autobahn’, Your highway system. Forcing the machine.
