Eric Schmidt, former CEO of Google, is building a huge space telescope. The question is not how, but why

by

If someone today wanted to build something like a new Hubble, it would make sense to think of years of reports, reviews and committees before the first piece of hardware is even manufactured. However, that logic has just been broken with an unexpected announcement: Eric Schmidt, former CEO of Google, and his wife Wendy have put on the table his own money to power not one, but four telescopes, including a large-scale space observatory. The move not only challenges the sector’s inertia, but raises a question deeper than budget or technology: what exactly is a former Silicon Valley executive pursuing by wading into the heart of modern astronomy. This is a project promoted by the Schmidt Observatory System, it seeks to cover everything from the deep sky to the detailed study of transient phenomena. A change of model. Currently, telescopes are generally in the hands of public agencies and academic consortia. Building ever-larger mirrors and then putting instruments into orbit turned astronomy into a matter of national budgets. The Schmidts’ entry into this arena suggests that, with new technologies and another way to finance risk, that historic balance could be starting to shift again. Risk, speed and open science. The approach behind the observatory system is not to compete with space agencies, but to cover the space left by their own processes, which are long, conservative and highly conditioned by public budgets. The Schmidts seek to finance concepts that have already been imagined by the scientific community, but that rarely overcome the barrier of official financing due to their level of risk or the deadlines they require. The piece that gives meaning to the whole and that really makes the difference is Lazulithe only one of the four projects that will leave Earth. It aims to cover a wide range of science, from transient events lasting minutes or hours to the detailed study of exoplanets, with a level of flexibility that large public observatories cannot always offer. Further, more agile. One of the clearest breaks between Lazuli and Hubble is where it will operate and how. While NASA’s telescope orbits about 500 kilometers from Earth, Lazuli will be placed much further away, in an elliptical orbit that should give it a clearer view and allow for fast and continuous data linking. Lazuli Space Observatory In the official description, Schmidt Sciences frames this operation in a “lunar-resonant” orbit. Added to this is a larger mirror, 3.1 meters compared to Hubble’s 2.4 meters, and an observation philosophy designed to react quickly to unexpected phenomena. One platform, several instruments. Lazuli is designed as a unique platform that integrates three instruments designed to cover everything from wide-field observations to the detailed study of exoplanets and transient phenomena. Wide-field optical imager with high cadence for photometric time series, 30′×15′ field of view and filters between 300 and 1000 nm Integral field spectrograph continuously covering 400–1700 nm, optimized for stable spectrophotometry and rapid sorting High contrast coronagraph to directly observe exoplanets and circumstellar environments, with contrasts of 10⁻⁸ and up to 10⁻⁹ after processing The era of array telescopes. Argus, DSA and LFAST They are not traditional telescopes, but rather distributed systems that take advantage of recent advances in computing, storage, and automated analysis. Instead of concentrating everything in a single structure, they distribute the collection of light or radio signals among tens or thousands of modules that are then digitally synchronized. This modularity aims to accelerate deployments and opens the door to observing the sky almost in real time, something fundamental for the astronomy of fleeting events. Render of the Argus Array (left), Deep Synoptic Array (right) Argus Array will bring together 1,200 optical telescopes in Texas to observe the northern sky almost continuously, with the idea of ​​being able to “rewind” what happened minutes or hours before an event such as a supernova. DSA, in Nevada and under the direction of Caltech, will deploy 1,600 radio antennas to map more than a billion sources and update its view of the sky every fifteen minutes. LFAST, for its part, will be installed in Arizona as a system of 20 80-centimeter mirrors aimed at large-aperture spectroscopy and the search for biosignatures, with a prototype planned for mid-2026. What the Schmidts have launched is, at its core, an experiment on the scientific system itself. Lazuli and his three colleagues on land aim to show that it is possible to build large-scale observatories more quickly and with an openness of data that does not always fit into traditional models. Whether that vision materializes will depend on factors yet to be determined, such as the final contractors, real costs or the feasibility of the schedules, but if it goes well, the impact will not only be measured in new discoveries, but in a new way of deciding what science is done.

We already have here the first trailer for ‘The Odyssey’ by Christopher Nolan, which, as expected, offers us an adventure that moves away from the environments that the director has frequented until now, but which nevertheless has a good part of the house’s trademarks: musical fanfare, impactful images and dense and solemn atmosphere. a genuine deli for devotees of the director. After releasing a six-minute prologue a week ago Exclusive to 70mm IMAX theaters, this new trailer takes us to the immediate aftermath of the Trojan War: a devastated battlefield where Odysseus, played by Matt Damon, kneels before a fully armored Agamemnon (Benny Safdie) and which some critics have already pointed out as unequivocal proof that historical rigor is clearly not going to be one of the film’s priorities. From there, pure icons of classic adventure: the hero and his soldiers crossing forests, navigating rough seas and entering dark caves. Damon’s voiceover tells that “after years of war, no one could come between my men and home. Not even me.” Significantly, we barely see Odysseus on screen. The trailer gives a good account of Nolan’s visual ambition: we see the Trojan horse being dragged from the sea by hundreds of unsuspecting Trojans, and how the warriors inside the gigantic structure experience it. We see a giant creature at the entrance to a cave, perhaps the cyclops Polyphemus. We see ships suffocatingly tossed about by real waves. An ambitious odyssey ‘The Odyssey’ represents an unprecedented leap in the use of the IMAX format. It is the first film in history shot entirely with IMAX cameras.something Nolan has pursued since he began incorporating the format into action sequences with ‘The Dark Knight’ in 2008. Until ‘Oppenheimer’, technical limitations (excessive noise, prohibitive weight, difficulty capturing dialogue) prevented its continued use. But for ‘The Odyssey’, IMAX developed a new generation of cameras 30% quieter and considerably lighter, making full filming viable. Principal photography lasted 91 days between February and August 2025touring Morocco (Aït Benhaddou to recreate Troy), Greece, Italy, Scotland and Iceland. The most reckless: Nolan spent four months in the open seawith the entire cast rolling on real waves. The budget amounts to $250 million, making it the most expensive film of his career. Nolan explained. that sought to identify absences in contemporary film culture. He concluded that Greek mythology had never received the big-budget Hollywood treatment with full dramatic credibility. Furthermore, he states, The Odyssey by Homer contains elements of horror, mystery, romance and thriller simultaneously. It is not a genre, it is the matrix of all genres. It is clear that Nolan wanted to put the emphasis on the physical: real ships almost submerged in the sea, armies of extras, the Trojan horse… at the moment we do not see the abundant mythological creatures that the story has (the Cyclops, the mermaids, the sorceress Circe), but possibly they have sought to contrast with the realism of the rest of the story. And we still have to see the bulk of the star cast (Zendaya, Robert Pattinson, Charlize Theron, Lupita Nyong’o, Mia Goth…). This Odyssey has only just begun.

China has been building the Great Green Wall for 50 years. What I had not planned was to alter the rains

by

The China’s forests are growing. It has nothing to do with a natural process, but with a meticulously followed strategy to contain the desert expansion and reforest the country with billions of trees. The consequence of this reforestation is not limited to having more trees and two studies have just shown the counterpart of massive ecological engineering. This is not good news: the continental hydrological cycle is being altered. The Green Wall. Of China’s deserts, the Gobi may be the best known, but the Taklamakan It is one of the most problematic. 85% of this 337,600 km² desert are dunes, which at certain times of the year generates sand storms that leave the surrounding towns without crops. And countries like the two Koreas or Japan too they suffered the effects of storms. Furthermore, it was growing, so in 1978, the country launched march the Refugio Tres Norte Forest Program. The strategy: a series of tree belts to contain the expansion of its largest deserts. The objective: to go from forest cover in the country of 5.05% in 1997 to almost 15%, and the idea is complete that belt by 2050 with a total of 4,500 kilometers long. At the moment, the Great Green Wall has completed the shield around Taklamakan with a belt of about 3,000 km, observing a decrease in sandstorms. Consequences in water. Apart from that desert, in others such as Ulanbuh, Korqin, Hunshandake, Maowusu and Kubuqi, tens of thousands of square kilometers of forest and pasture have been built. And, although the storms have decreased, different investigations are noticing a secondary effect: an alteration of the water cycle throughout the continent. Published in Earth’s Future, a study carried out by Chinese researchers shows how new vegetation has increased evapotranspiration in the region. Bottom line: More water is being pumped from the ground into the atmosphere, meaning winds are transporting water to regions like the Tibetan Plateau as rain while the monsoon regions of the northwest and east are suffering a decrease in its net water availability. Non-uniform redistribution. This greater green cover causes restored forests and grasslands to transpire more water than bare soil or traditional crops. This additional moisture It enters the atmosphere, which falls in other regions as rain. According to the study, the consequences at the national level were the following: Evapotranspiration increased by 1.71 mm/year. Precipitation also increased by 1.24 mm/year. Water availability (from aquifers and springs, for example) decreased by 0.46 mm/year. And, as we say, the process is not uniform because the water is moving from one area to another. Greening/conserving water. It is not the only study published on the subject, but it is one that coincides in time with another published in August of this year in which, after analyzing 1,046 hydrological stations and their data from the last 60 years, they discovered that the flow of the rivers decreased by more than 70%. Their conclusion is that it is not an effect of climate change, but of changes in the landscape caused by human intervention. It makes perfect sense: trees need water to grow, and that amount of new trees makes them act like a giant pump, reducing the amount of water that feeds the rivers. Thus, there is a tension between greening China and conserving its water, since once in the clouds, it precipitates air currents wherever you go. Implications. In the end, the researchers conclude that the strategy when managing water must be changed and that hydrographic plans must take into account both the land basins and the “air basin”, anticipating where the water evaporated by the forests will travel. Because the ambitious reforestation plan has 24 years left and the country has invested a lot in it directly – by planting trees – but also with policies that prohibit the felling of forests or with incentives for farmers to convert their croplands into pastures. And, well, the consequences not only have to do with water. That the Natural Forest Protection Program prohibited logging in primary forests provoked that Chinese loggers would ‘loot’ the Burmese forests. Something that adds to the conflict between both nations.

Huawei is building its own alternative ecosystem to CUDA. If it succeeds, NVIDIA will have a serious problem

by

When talking about NVIDIA, almost all the focus is on the hardware: the H100Blackwell, racksenergy consumption, nanometers… It is understandable, but it is a mistake. The defensive moat – the moat– NVIDIA is not the hardware. Is CUDA. CUDA is not an add-on to the chip, it is the de facto standard upon which most of the AI ​​code on the planet is written, optimized and debugged. Changing GPUs without changing CUDA does not exist. And switching from CUDA means rewriting years of work. That is why it is a moat. Why is it important. Huawei’s big bet is not to “make a Chinese H100.” It is to build a path for the developer to reach Ascend without feeling like you are changing planets. The restrictions are accelerating it. Exports have split the world in two: An ecosystem that revolves around NVIDIA. And another that China is trying to lift against the clock. In that second, Huawei is not just playing chips: is playing “ecosystem”in AI and outside of it. And therein lies the nuance: you can be years behind in chips and still reduce dependency if you get the software to swallow. In detail. Huawei is attacking the problem on three fronts, with a pragmatically Chinese logic: not to replace everything at once, but to open shortcuts. Native stack (CANN + MindSpore). It is your “pure” alternative: your own environment and your own tools to get the most out of Ascend. The cost today is high, there are complaints of instability, the documentation is rather messy, and the community is much smaller. PyTorch support. This is the most strategic move. Huawei does not try to make the world love its framework– Try to ensure that the world doesn’t have to leave PyTorch. torch_npu acts as an adapter to run PyTorch models on Ascend, but with one problem: it is not native and suffers with every PyTorch change. If PyTorch advances and your backend lags behind, the developer notices. Portability via ONNX. Here Huawei looks for its best window: inference and deployment, not training. ONNX works as a bridge format: you train where you can (often NVIDIA) and deploy to Ascend. It’s a less romantic and more useful approach: if shortages hit, moving inference to local hardware is an immediate relief. Between the lines. The real story is that Huawei is trying to replicate the “trick” that made NVIDIA great: turning its hardware into an experience. That’s why the tactic that explains everything appears: putting engineers in the client’s home to migrate code and optimize it. It is not scalable as a business model, but it is scalable as a transition model: you buy time while you mature tools, libraries and support. And there is another derivative: if China gets enough teams to adopt Ascend out of necessity, over time that can become habit and then infrastructure. Not because it is better, but because it is already integrated. Yes, but. Huawei has two limits that cannot be fixed with marketing: Hardware improvement rate: Roadmap analysis suggests relative stagnation and a gap that could widen, not close, if NVIDIA continues to accelerate cycles. Off-chip bottlenecks: memory (HBM), tools and industrial capacity. You can add “worse” chips, but you need to make a lot of them and build a lot of systems. And now what. If this movie continues, we will see two clear signs: Less hype of chips and more real migration stories: how many computers have moved to Ascendwith what frictions, with what performance losses. Less obsession with training in Ascend and more normalization of the hybrid pattern: I train where I can, I deploy where I must. NVIDIA will continue to be CUDA. Huawei is not “a chip.” It is an escape strategy. And the restrictions are the fuel that is making it inevitable. In Xataka | With HarmonyOS NEXT Huawei has achieved something incredible.

China is building a megastructure for deep-sea research. For whatever reason, resist nuclear bombs

by

China is building a mega thing. It doesn’t matter when you read this: the Asian giant always has a mega dam underwayhe highest bridge in the world either an impossible road in the bag. However, one of the country’s latest projects is not a mega-construction, but a floating artificial “island,” which can navigate and designed to be self-sufficient. Oh, and most importantly: prepared for the end of the world. The “island”. Waiting for it to receive a somewhat more “commercial” name, in a report by South China Morning Post They refer to the facility as the “Deep-Sea All-Wather Resident Floating Research Facility.” It is a name that is equivalent to “what do you want this station to do” and the answer is “yes,” and it is basically a mix between a research center, command center and nuclear bunker. It will be a semi-submersible platform with a 78,000 ton twin hull design and considerable dimensions: 138 meters long. 85 meters wide. Main deck 45 meters from the waterline. Long duration missions. The project specifications show that the platform is projected to house almost 240 people for four months without the need for any replenishment. In addition, it can sail at a speed of up to 15 knots and something that gives us a clue to its colossal ambition is that the engines allow a displacement comparable to that of the Fujian, the brand new Chinese aircraft carrier of 80,000 tons. Bomb proof (nuclear). If you’re thinking about a fortress that could be worthy of a Marvel movie, here’s the shot. The structure will resist waves up to nine meters high and category 17 typhoons, the highest for this type of cyclone. But the most striking thing is that it will have special armor to resist nuclear explosions. Instead of conventional steel armorthe walls of the complex will be built with a design that converts the powerful shock waves of a nuclear explosion into ones that the structure can assimilate. As a “dissipator” of the power of the wave, wow. To do this, they have resorted to a metamaterial which, when subjected to pressure, compresses, creating a denser and stronger structure than much thicker steel panels. According to simulations, its walls resist more pressure than those of a submarine and four times more than those of a conventional ship, but with a plate thickness of only 60 mm. Back.To withstand these long periods at sea, and as describe from Shanghai Jiao Tong University (SJTU) in an article in which they talk about the superstructure, the installation contains critical compartments that guarantee emergency power, but also backup for communications and a navigation center equally protected against nuclear explosions. China is taking leaps and bounds in its fleet Strategy. The SJTU describes it as a research center and, although the project has been described as “civilian”, its specifications make it comply with the Chinese military standard GJB 1060.1-1991 against nuclear explosions. Therefore, although it can be used for deep-sea research, it could also operate in areas where warships could not be accessed (such as waters near diplomatically sensitive countries or territories). This is something that does not frighten a China that does not hesitate to deploy its ships in disputed territoriesand from SCMP they point out that the installation could function as a resilient command center, a logistics center or a surveillance station that, in addition, is less invasive than a fixed structure built on land. It’s not that far away. Although we now know of its existence, this station has been on the drawing board for a decade and is expected to reach operational status in 2028. Once completed, we will be able to see what it is capable of and, above all, what use it is given. Because therein lies its importance as a research center to support the “blue economy” (extraction of deep sea resources, renewable energies and marine research), but also its military component. The photo, by the way, is not of a real structure, but of an interpretation of the SJTU.

There are those who think that the housing crisis can be solved by building. At the Polytechnic University of Catalonia they believe they are wrong

by

Spain has a problem with housing. That is an (almost) objective fact. The CIS says so, which places it as the great concern of the Spanish, but a quick review of the newspaper archive arrives to confirm it. During the last months few topics have generated more political debate or have taken out so many people on the street such as difficulties in accessing a home. What is no longer so clear is how to solve this “crisis” residential area recognized by the Government itself. Should we build more houses? Does Spain suffer from a housing deficit? Do we need more land to build? Usually the answer to those three questions is a strong ‘yes’. Now a new study signed by two professors of the Polytechnic University of Catalonia (UPC) and published in a magazine linked to the Ministry of Housing points out that perhaps we were wrong. What has happened? That two professors from the Higher Technical School of Architecture of Barcelona (ETSAB), Blanca Arellano-Ramos and Josep Roca-Cladera, have published a study about the problems that Spain is facing in terms of housing. The report in question is titled ‘Five theses about housing policy in Spain’ and is included in a monograph of CyTETa magazine published by the Ministry of Housing. So far nothing exceptional. The curious thing is that the text questions many of the ideas rooted in the real estate sector, such as that our country suffers from a housing deficit or needs more land to build. While the Bank of Spain (BE) estimates 700,000 homes the mismatch between supply and demand, the study questions whether there really is a ‘hole’ in the market or that prices will go down if we build more. Is there a housing deficit? As already indicated in its title, the article is structured around five theses. And the first addresses precisely that point: Does Spain suffer from a housing deficit? The question is interesting because it is one of the most deeply rooted ideas in the sector. The Bank of Spain itself has calculated that it would be necessary 700,000 houses to meet residential demand. For Arellano-Ramos and Roca-Cladera the reality is quite different. In his opinion, one cannot talk about a deficit without first taking into account the excess of housing accumulated between 2011 and 2021 and the stock of vacant properties. The researchers remember that between 2011 and 2021 the housing stock exceeded the growth in the number of homes by 959,554 units, generating a considerable pocket. In fact, they assure that in 2021 the “accumulated excess” was close to 8.1 million properties, a “‘cushion’ more than enough to absorb temporary housing deficits such as the one produced during the 2021-2024 period,” recalls the UPC in the statement in which he reports the study. What does that mean? That for researchers it is not so obvious that Spain suffers from a shortage of new housing. In their analysis they also remember that a good part of the excess of houses and apartments corresponds to second homes and empty homes. The INE itself estimates that at least in 2021 there were 3.84 million of uninhabited properties, 14.4% of the real estate stock. That percentage far exceeds what most experts consider “desirable” (5%), but at least in the statement The UPC does not address another fundamental aspect: the distribution of these wasted properties, if they are located in stressed markets, such as Madrid, Barcelona or Malaga, or in centers where demand is minimal or even non-existent, in the case of emptied Spain. What if we build more? That is the second question the researchers address. What if we build more homes? Would prices be reduced? Their response is once again skeptical to say the least: increasing buildings will not lead to greater social equity nor will it serve to soften prices. “On the contrary”, slide the UPC note. “According to the authors of the study, the solution is not to build more new homes so that the laws of the market balance prices. In addition to having serious environmental effects, what favors is the real estate bubble like the one that occurred around 2000.” What happens in other neighboring countries? Among other arguments, Arellano-Ramos and Roca-Cladera recall that the rise in prices is not a problem exclusive to the Spanish market, but rather something widespread on the continent. So the question is obvious: if the increase in prices is due to the imbalance between supply and demand, do the majority of EU countries share that same problem? “Is there simultaneously a restriction of supply in relation to demand occurring throughout Europe in relation to demand that explains the increase in residential prices? It does not seem that this is plausible. Therefore it is not reasonable, prima facieturn to the scarce construction of new housing as the main cause of the price of housing”, they reflect the authors before remembering that Spain has invested a higher percentage of GDP in construction than the European average. Do we need more land? The researchers also question whether in Spain the problem of lack of accessibility to housing can be explained by the scarcity of land. And to prove it, they go to the newspaper archive: between the late 90s and the early 2000s, buildable land was made available in the country, which allowed for “massive construction” of residential housing. This boom was not accompanied, however, by a reduction in the price of the square meter. Quite the opposite: residential prices increased, as in other parts of Europe. If Spain saw housing prices rise between 1996 and 2008, it was not because there was no land on which to build or build new homes. “Spain became more urbanized than ever and the result did not represent a reduction in prices, on the contrary,” underlines the UPC in your statementwhich recalls that between 2000 and 2012 Spain was the European country with the greatest “consumption” of land: more than 2,400 square kilometers (km2), almost as … Read more

the Stadler plant will be responsible for building 200 hybrid locomotives

by

Stadler, a well-known Swiss manufacturer responsible for producing railway equipment, has announced a historic contract with the Luxembourg locomotive rental company Nexrail. The idea is to build up to 200 hybrid locomotives EURO9000. Although the company has not revealed official figures, according to According to Expansión, the order could reach 1.4 billion euros, taking into account that previous similar contracts have been around 7 million per unit. And why is all this important? Precisely because all production will be carried out at Stadler’s plant in Albuixech, Valencia. A boost for the Valencian industry. This mega order represents a fairly important injection of work for Stadler’s Valencian factory and consolidates its position as a strategic production center within the Swiss group. The Albuixech plant will be responsible for manufacturing the most powerful locomotive which is currently produced in Europe, a great recognition of the technical and industrial capacity that the Valencian factory provides. Hybrid technology. The EURO9000 hybrid It combines pantograph and batteries on a six-axis platform already proven on the market. With its multi-system design it allows it to operate without problems between borders of Germany, Austria, Belgium, the Netherlands, Switzerland and Italy. In addition, it can transport goods completely emission-free from terminal to terminal, which leaves aside diesel, a fuel that still predominates in many European corridors. Power. According to Stadler, these locomotives can operate alone even on the most demanding routes, such as transalpine corridors, without the need for an additional thrust locomotive. In direct current networks, the battery system provides extra power that improves performance and allows more load to be transported. It also offers an intelligent battery management system that optimizes regenerative braking, which reduces costs during peak electrical consumption and allows energy to be purchased at times of lowest price. The client and the first operator. The first user of these locomotives will be Hamburger Rail Service (HRS), according to has confirmed Stadler. “The EURO9000 with pantograph and batteries offers HRS a unique combination of flexible traction on lines with or without catenary, high traction capacity for our heavy loads and zero-emission operations,” explained Adem Gülaz, CEO of HRS. Decarbonization. Iñigo Parra, president of Stadler Valencia, has underlined that the order “reveals our joint commitment to sustainable innovation in rail freight transport.” For his part, Luuk von Meijenfeldt, CEO of Nexrail, highlighted that the company is “excited to lead the European locomotive market towards a zero-emissions future” and that this order marks “an important step in that transition.” Europe’s goals. The rail freight sector is immersed in a transformation process to meet European climate objectives, similar to what’s happening right now in the automotive world on the continent. Complete electrification of all lines is still economically unfeasible, so hybrid locomotives with batteries are now emerging as the most realistic solution for decarbonize the sector without giving up the operational flexibility that diesel locomotives still offer on non-electrified sections.

The Star Destroyer is the terror of Star Wars. But as one fan has calculated, building it in real life wouldn’t be cheap.

by

‘Star Wars’ is full of iconic ships. From the Millennium Falcon and its Kessel Corridor in just 12 parsecs to silhouettes identifiable at a glance such as the X-Wing or the TIE Fighter. We associate ‘Star Wars‘ with frenetic combats in space, but we also have iconic mastodons, authentic galactic monsters like the unmistakable Imperial Star Destroyer. Well: now we not only know how much it impresses us, but also how much it would cost us. What is a Star Destroyer. This 1.6 kilometer long, wedge-shaped beauty exhibits measurements and characteristics that make it a mini space station of considerable power. Let’s see: Approximate mass: 40 million metric tons Engines: Three KDY Destroyer-I ion engines and Cygnus Spaceworks Gemnon-4 units Maximum speed in atmosphere: 975 km/h Hyperlight Capability: Yes, with a class 2 impeller Heavy and medium turbolasers located in batteries throughout the ship Ion cannons to disable enemy systems 30 torpedo launchers or missile slots Ability to deploy 72 TIE fighters, as well as AT-AT and AT-ST ground vehicles Estimated total crew: between 37,000 and 60,000 people It functions as a small floating city, with areas for operations, daily life, maintenance and storage So the money what. Although less monumental than the Death Star, Star Destroyers require immense resources to construct. Estimates based on scientific analysis and data from the saga and collected on the website Gamestar They suggest that building, maintaining, and even disposing of when the time comes for a single Star Destroyer could cost a fortune. Used as a basis for comparison the price it costs to build a real aircraft carrier: between 13,000 and 17,000 million dollars each. And that’s just the beginning. We’re not just talking about construction itself. Resources and construction time skyrocket when considering mass production, as the Empire deploys dozens of destroyers to maintain its dominance. In addition, training and supplying personnel generate recurring costs. And maintenance, of course: refueling, repairing war damage, technological updates and replacing parts, which requires the construction of strategic space bases. We are going in parts, breaking down this authentic black hole of pasta. The initial transport. Transporting 40 million tons of construction material to space is logistically complex and expensive. With an extremely optimistic price of 10,000 euros per ton, the initial cost would be around 400 billion euros. In the long term, the cost could be reduced to about 200 euros per kilo, equivalent to about 8 billion euros. If we talk about current technologies (that is, no teleportation or similar), the realistic cost for this volume would be around 40 billion euros. What the material costs. The construction of the Star Destroyer would likely use high-strength, low-alloy steels, the cost of which is estimated at around €90 billion. More advanced systems such as propulsion, weapons and other high-performance components would require more expensive special alloys, adding at least an additional 110 billion euros. Altogether, conservative estimated costs for materials would be around €200 billion in total. To ride. The Star Destroyer is significantly more expensive to manufacture than mere materials, as labor and countless tests can cost five to fifteen times as much. The construction cost is estimated at around 2 billion euros. Furthermore, adding the costs of research, testing, infrastructure and development, especially in new energy and propulsion systems, could conservatively add another 5 billion euros to the total budget. The invoice. In short, these gentlemen will have to go and digest: the total expense to build and maintain the imperial Star Destroyer is estimated at around 15.2 billion euros, assuming transportation costs. Without including development expenses, the cost would be around 14 billion euros. But we can go up: if additional elements such as technical reserves, energy systems, lifetime maintenance and scrapping are considered, the joke can approach 40 billion euros. To put it in perspective, the USS Gerald R. Ford aircraft carrier cost around 12 billion euros, so a Star Destroyer would cost almost four thousand times that amount.​ In Xataka | Adam Driver launched a Star Wars movie project about Kylo Ren.

If when you think of a farm you visualize a red building with white corners, it’s the Swedes’ fault.

by

5040-Y80R. That is the approximate designation according to the Natural Color System chart for color ‘red falu‘. It is a registered trademark and It goes beyond being a simple color: implies that a very specific pigment comes into play in its production that gives it that reddish tone and has transcended to the point of being part of the identity of an entire country thanks to its properties. That country is Sweden, and it all started as a waste product from a copper mine. By-product. Dalarna is a region located in the heart of Sweden, and it is home to the Falun Great Copper Mountain. The Vikings They were already exploiting this mine in 850, but the history of color dates back to the 16th century. It was then that they discovered that one of the mining byproducts could be turned into a useful pigment. Leaf From the production of copper they obtained what they called Falu rödfärgor “red mulch,” and was basically a unique mixture of over 20 different minerals. The reddish color was thanks to iron oxide, silica, zinc and copper itself. They started to mix it up with water, but also with other elements such as oils, tar or rye flour, and they discovered that they could obtain a paint with very interesting properties. better than paint. This red mulch mixed with the appropriate ingredients not only gave color to the wood, primary raw material in Sweden for both ships and infrastructure, but also acted especially well as a material protector. It was like an insulating layer, a shield that protected against the elementsprolonging its useful life, making repairs less frequent and, in addition, it was cheaper than importing wood treatments from other countries. The industry soon exploded. HE esteem that, by mid-1760, production was about 25 tons, but by 1930, that annual production exceeded 2,000 tons. Status. Now, it wasn’t cheap. Everyone wanted to paint their house that copper red color, but it turns out that it was a luxury reserved for the highest classes. When the pigment was discovered, and perhaps motivated only by its color, King John III ordered paint the ceilings of his palace with ‘falu red’, imitating the copper of the ceilings of other European palaces. Since then, those with the most power who could get hold of the pigment began to paint their houses. However, as production began to scale and gain traction, the product became cheaper and more people were able to access it, painting, if not all of their houses, the façade that faced the roads (which was what everyone passing by could see). Swedish edges of the 19th century contributed to popularize the image of the red houses of Sweden, immortalizing the idea of ​​rural life in red houses with white corners. One of Carl Larsson’s works The color of a nation. The color 5040-Y80R became the symbol of Sweden to the point that migrants who sought better luck in North America after the dissolution of the norwegian swedish union In 1905 they began to build their farms using this color. The image that many of us have of the red farm was created there. And it became so important to Swedish popular culture that there is a saying that symbolizes that simple life and harmonious in contact with the earth: den röda stugan och potatislandet (the red house and the potato garden). Today, the ‘Falu rödfärg’ is not as vital as it was years ago if we talk about production. The same has descended a lot because there is greater competition and synthetic products for paint the facadesbut it is still an example of “banal nationalism”, a symbol that exists without the need for flags and anthems, since its mere presence evokes belonging.

Building data centers in space was the new hot business. Elon Musk just broke it with a tweet

by

The debate over the feasibility of building gigantic data centers in orbit had been heating up for months. It is Silicon Valley’s new big idea to solve the insatiable energy appetite of artificial intelligence. Until, as usual, Elon Musk has entered the conversation with the subtlety of a hammer. Elon Musk has joined the chat. After weeks of debate about the feasibility of building servers in space, Eric Berger, editor of Ars Technica, argued that will end up being a more plausible option when the technology exists to assemble satellites in orbit autonomously. It was the moment chosen by Elon Musk to enter the conversation. “It will be enough to scale the Starlink V3 satellites, which have high-speed laser links,” wrote the CEO of SpaceX. “SpaceX is going to do it,” he said. A phrase that has probably fallen like a blow on startups that are taking advantage of the momentum of AI to go out in search of financing. Why the hell do we want servers in space? The idea of ​​moving computing to Earth orbit responds to a very real crisis: AI is an energy monster, and Demand for data centers continues to grow. Given this panorama, space offers two advantages that are impossible on Earth: Almost unlimited energy: In a sun-synchronous orbit, solar panels receive sunlight almost continuously (more than 95% of the time). Free Cooling: Land-based data centers consume millions of liters of fresh water to cool. With a large enough radiator, the gap can be “an infinite heatsink at -270°C.” The heat would be radiated into the vacuum without wasting a single drop of water. The new titans of space AI. Musk is not the first to see the business. In fact, he arrives at a party where the first contracts are already being distributed. Jeff Bezos predicted during the Italian Tech Week that we will see “giant training clusters” of AI in orbit in the next 10 or 20 years. Eric Schmidt, the former CEO of Google, bought rocket company Relativity Space precisely for this purpose. And Nvidia, the undisputed king of AI hardware, has actively backed startup Starcloud, which plans to launch the first NVIDIA H100 GPU into space this November, with the goal of eventually building a monster 5-gigawatt orbital data center. Why Musk would win. The vision of Bezos, Schmidt and Starcloud faces two colossal obstacles: the cost of launch and the construction of the servers themselves. Calculations for a 1 GW data center would require more than 150 launches with current technology. And Starcloud’s plan for a 4 kilometer wide array is a logistical nightmare. Elon Musk has Starship, the giant rocket on which all of his competitors’ business models depend to be profitable. And you don’t need build a new orbital data center. Just adapt and scale the one you already have. 10,000 satellites and counting. SpaceX’s Starlink constellation no longer competes against satellite internet, goes for terrestrial fiber. Musk’s company has already launched 10,000 satellites and is preparing the deployment of the new V3 satellites, designed for Starship with high-speed laser links. According to SpaceX itself, each Starship launch will add 60 terabits per second of capacity to a network that is already, in practice, a global computing and data mesh. While Starcloud needs to hire a rocket and assemble 4km-wide solar and cooling panels, Musk simply needs Starship to finish development to continue launching satellites.
