If the solution to the housing crisis in Spain is “building taller buildings”, Alcalá de Henares has taken it seriously

by

If you want to solve your residential deficit and stop the upward spiral of prices, Madrid needs housing. tens of thousands of housing, if we trust the calculations carried out by the real estate sector. With that backdrop in the capital (as in other points of the country) has opened a debate: Should we look up? That is to say, if houses are needed and the buildable land is what it is, has the time come? replant the height of buildings, both in established neighborhoods and in new real estate developments? In Alcalá there are those who believe so. In fact, the birthplace of Cervantes has started the countdown to provide one of the tallest skyscrapers in the community, a tower of almost 30 levels. What has happened? That Alcalá de Henares seems to have unblocked an ambitious real estate project that it had been years on the table: a tower that, once completed, will become one of the tallest residential buildings in the Community of Madrid. The news has revealed it the company Ten Brinke, which has partnered with Invesco Real Estate to carry out the operation. Although not many details of the project have been revealed, it is known that the building will be around 30 floors and will exceed the 300 homeswhich will redefine the skyline of the city and will surpass La Garena, an office tower 17 floors and 71.7 m which now dominates the town’s skyline. There are those who now slide that the new construction will be the first residential skyscraper in Alcalá de Henares and one of the few in the Community of Madrid that exceeds 25 heights. What do we know about the project? In the statement In which he announces the “closing of the operation”, Ten Brinke slips a couple of clues about the future property: it will be residential, it will exceed 300 homes and will have 28 levels in total, a sum of 25 floors in height, the ground floor and two underground levels. Furthermore, Ten Brike clarifies that the developers will bet on a “product mix” formula, including family housing, premium apartments and “spaces aimed at modern living.” Regarding deadlines, he states that the works will start “in the coming weeks”, without outlining a delivery schedule. Has anything else transpired? In recent days the Madrid press has pointed out various details to adults, such as that the objective is for the homes to be used for rental marketthat the tower will be around the 80 meters high and that will be located in the Francisco Anton streetnext to the new GAL neighborhood. The SER chain assures that the project has actually been licensed since 2021. A few years ago was announced an ambitious residential development, the Tower (or garden) Cervantes, with buildings 25 stories high. The Idealista portal even reached advertise The apartments, which were offered from 256,000 euros and also stood out for their common areas, with more than 15,000 m2 of gardens and recreational areas that included an outdoor pool. At that time (2024) the idea was to deliver the first keys towards the summer of 2027. Why is it important? Beyond the relevance of the project and its impact on the Complutense skyline, the tower is important because it will inject 300 new homes in a town that has seen how rents and the price per m2 have become more expensive in recent years, in line with the rest of Madrid. According to the Idealista portal, in February the m2 It cost €2,74419.3% more than in the same month last year. Regarding the rent, the m2 It was rented for €13.7which represents an annual increase (February 2025) of about 12%. The municipality has also seen its registry grow in recent years, going from 193,751 registered in 2018 to more than 203,200 residents, according to the tables of the INE.

While everyone looks at Iran, China is building a nuclear “Great Wall”

by

Under the surface of the oceans one of the technological competitions is taking place quieter and more decisive of the planet. The nuclear submarines They can remain submerged for months, travel halfway around the world undetected and launch missiles from thousands of kilometers away. Therefore, each new advance under the sea usually anticipates much bigger changes in the global strategic balance. Washington’s alarm. While much of international attention is focused on the immediate conflicts in the Middle Eastanother much deeper strategic concern is beginning to take shape in Washington. Apparently, the US Navy commanders have warned before Congress that the military balance under the sea is changing rapidly and that China is accelerating a transformation process that could alter the global nuclear deterrent in the coming decades. The underwater race. we have been counting in recent months. China already owns one of the largest submarine fleets in the world and is expanding it at high speed thanks to massive investments in its military shipyards. Production has gone from less than one nuclear submarine a year to significantly higher rateswith forecasts that the fleet will reach around 70 units by the end of this decade and close to 80 by 2035. Although the United States still maintains a technological and operational advantage in submarine warfare, the rapid growth of Chinese industrial capacity is reducing that distance and forcing Washington to rethink the strategic balance in the Pacific. The transition to a nuclear fleet. One of the most important changes is structural. For decades, the Chinese submarine fleet has been based on diesel-electric vessels, which are cheaper, but have less autonomy and must surface frequently. Now Beijing is promoting a strategic shift towards more and more construction focused on nuclear submarinescapable of remaining submerged for long periods and operating at great distances from their bases. This change will allow the Chinese navy to project a presence beyond its immediate environment and complicate US naval operations. in the Pacific and other oceans. The new submarines. The technological leap will come with new generations of submarines that will begin to enter service between the end of this decade and the 1930s. Among them stand out the Type 095 models and, above all, the Type 096designed to transport nuclear ballistic missiles long range. We are talking about equipped boats with JL-4 missilessubmarines that will be able to attack large areas of US territory even operating from waters near China, much more protected by its naval and air defenses. Such a capability would significantly bolster the credibility of China’s nuclear deterrent and reduce the need to patrol more exposed areas of the Pacific. A network to protect the nuclear deterrent. Plus: the Chinese project is not limited to building more submarines. American commanders said that Beijing is developing an extensive sensor network on the seabed, surveillance cables, satellite-connected buoys and unmanned underwater vehicles capable of detecting movements in nearby oceans. This system, described by many analysts as an “underwater Great Wall,” would allow China monitor strategic routestrack foreign submarines, and protect its own nuclear fleet while patrolling in relatively safe waters. The strategic horizon of 2025 and 2040. The result of this transformation should be seen clearly in the next decade. As the number of nuclear submarines grows and this undersea sensor network is deployed, China could greatly expand its underwater presence. beyond the first chain of western Pacific islands. US forecasts suggest that, around 2040Chinese submarines could operate more frequently in the Indian Ocean, the Arctic and even the Atlantic. If this evolution is confirmed, the global naval balance could enter a new phase marked by a fearsome underwater competition between the two greatest powers on the planet.

Sam Altman says he’s terrified of a world where AI companies believe themselves to be more powerful than the government. It’s just what you’re building

by

Sam Altman sat down over the weekend before his audience at X to answer questions about the agreement that OpenAI has just signed with the United States War Department. What came out of that session was a beautiful involuntary x-ray of the biggest contradiction in the sector at the moment. Why is it important. The CEO of OpenAI said he is terrified of “a world where AI companies act as if they have more power than the government.” The phrase sounds good, it is marketinian and seeks to elevate OpenAI’s position as a powerful but very responsible and honest group. The problem is the context in which he pronounces it: hours before OpenAI signed that agreement, The US government labeled Anthropic, its direct rival, a “supply chain risk” for refusing to sign under those same conditions. Altman went to put out the fire just as someone accused him of setting it. Between the lines. Altman’s speech rests on a premise that must be monitored: that a democratically elected government must always prevail over unelected private companies. It is a philosophically reasonable position, but he applies it selectively. Altman acknowledged that the deal “was rushed and the picture is not good,” and that OpenAI moved quickly to “de-escalate” tension between the Pentagon and industry. In other words, your company made a unilateral strategic decision about how the entire AI industry should relate to the military establishment. That doesn’t exactly sound like institutional deference. The contrast. Anthropic opted for something different: requiring explicit safeguards against the use of its AI for mass surveillance or autonomous weapons. But the government penalized her. OpenAI accepted a more ambiguous formula (“for all legal uses”) and won the contract. Various OpenAI employees signed a letter supporting Anthropic’s position. Claude became the most downloaded free application in the App Store that weekend from Apple, precisely surpassing ChatGPT. The market also has opinions. Yes, but. It’s fair to admit that Altman’s position has some internal logic: If AI is going to be integrated into military systems anyway, it may be preferable that it do so under negotiated conditions rather than under coercion. And he’s right about one thing: The labeling of Anthropic as a supply chain risk, a tool intended for hostile foreign suppliers, applied to an American AI security company is, in his own words, “an extremely frightening precedent.” The big question. Who really decides how AI is used in military contexts? The companies that build it, the governments that hire it, or the engineers who design it and who are increasingly organized to influence those decisions? Altman says he believes in the democratic process. But OpenAI negotiated privately, signed privately, and made only a fraction of the contract public. Democratic transparency starts there.

Meta was building its AI chips to not be dependent on NVIDIA. Has ended up surrendering to the evidence

by

Meta faces a crucial year. While its competitors were laying the foundations for AI, Meta was burning money in the metaverse. That, along with a totally different approach to what Google or OpenAI were doing with AI, caused Zuckerberg’s company to pass a few years in the gutter. After reorganizing the house and sign the AI ​​A-TeamMeta was preparing so much a great model as new own chips for training. The thing… hasn’t turned out as expected. MTIA. Within the different Meta teams focused on artificial intelligence, there is one known as MTIA. It comes from ‘Meta Training and Inference Accelerator’ and its objective was research and design own chips training for artificial intelligence. Having your own chip makes all the sense in the world, since it is designed based on the needs you have. They have another advantage: you are not dependent on anyone else. If NVIDIA doesn’t have enough chips, it doesn’t matter because you have yours and can continue scaling data center systems (and those of Meta are immense) to continue the training and inference tasks. Meta was not going to be in charge of manufacturing, something that the highly reputable TSMCbut the program got off to a bad start. This is very difficult. Reuters He already mentioned it last year. After testing his first in-house developed training chip, Meta realized that things were not going well. It was underperforming what they expected, and it was also worse than the competition. They did not throw away the chips, but instead referred them to other systems (such as those for recommending Facebook and Instagram based on algorithms). The problem is that the performance of the training chip, the one really important for the AI ​​career, was not enough. Strategy change. In The Information They echo a statement from Meta stating that the company remains committed “to investing in different silicon options to meet our needs, which includes the advancement of our MTIA division” and they urge us to remain attentive to news that will be shared throughout this year. However, in the same medium it is noted that Meta has greatly lowered its expectations with its chips. The idea was to have two chips. On the one hand, Iris, a single instruction training chip that is easy to design, but from which it is difficult to extract all the juice in these training tasks. artificial intelligence training. On the other hand, Olympus, a chip that would be completed towards the end of this year and that would be the central part of Meta’s training clusters. According to The Information, there were many internal doubts about the stability of Olympus, its intricate design and profitability, so they have left it in the drawer to focus on more “simpler” chips. The evidence. In the end, if you can’t beat your “enemy”, join him. The sources consulted by The Information point out that, in addition to other complications, the training software was not as stable as what alternatives such as those from NVIDIA offer. And all of this has ended up causing two multimillion-dollar agreements. In a period of just a few days, Meta signed agreements with both AMD and NVIDIA so that both can supply them with chips to train the AI. It’s a win-win for everyone because Meta receives what he needs, NVIDIA has another client on a list it dominates and AMD continues to make a name for itself in the sector thanks to agreements like this one or the one they signed last year with OpenAI. In addition, Meta secures several sources so as not to depend only on one company. In fact, it is also estimated that they have signed an agreement to rent TPU units from Google. The competition. Meta’s objective, therefore, is to diversify its portfolio of AI chip suppliers as much as possible while continuing to investigate its own chips of which, supposedly, we will learn details later. They may continue investigating Olympus or a variant or decide on another approach. Because what is clear is that they must develop something ‘own’. NVIDIA and AMD are suppliers, not competitors as such. The real competition is OpenAI, X and Google, and the last two have their factories at full capacity. Google with its TPUsprocessors designed exclusively for AI, and xAI with its own chips that they abandoned and picked up more recently. Objective: dethrone NVIDIA. And all this occurs in a world in which everyone is ‘friends’, but enemies at the same time. I already say that NVIDIA is a hardware supplier, but they practically control the AI ​​​​computing market and are moving both in hardware and software. It is logical that other companies are investigating alternatives to boost their own AI. Added to the list is an Amazon that is also manufacturing some chips called Trainium3 UltraServer and OpenAI with its agreement with Broadcom to manufacture chips. It is, as I say, a curious scenario: everyone needs each other, and there is the “circular economy” of AI, but at the same time everyone wants to be independent. The problem is that NVIDIA has a huge advantage in this and has both the technology and the contracts with memory companies… and the contacts with which it ends up manufacturing the best chips: TSMC.

China is building submarines faster than anyone else. And that’s a problem for the United States.

by

In a tense geopolitical moment on a global scale with several open fronts such as Greenland, whose melting ice is allowing us to see nuclear submarinesChina just achieved a historic milestone: it is manufacturing nuclear submarines faster than any other country in the world, according to a report by the International Institute for Strategic Studies. This is a complete surprise to the United States, the power that until now held this title, and threatens the advantage that Washington has maintained for decades. Brief notes on nuclear submarines. Without wanting to delve into their characteristics, it is worth distinguishing what types there are: He SSBN is a nuclear-powered submarine designed to launch ballistic missiles with nuclear warheads (some with intercontinental range). They are strategic second response platforms, practically undetectable and guarantee that if someone attacks first, they will receive a response. The SSN/SSGN are nuclear attack submarines (the second, guided missiles), true maritime control weapons: they can attack land or sea targets, block routes and operate for months without resupply. Context. American hegemony underwater lasts for decades, but Beijing has on its roadmap modernize its military capabilities by 2035: it already has the largest surface fleet in the world in the words of the Pentagon and now he has turned on the turbo to reach the last bastion of the United States: the depths. The data. China has surpassed the United States in the pace of launching nuclear-powered submarines (SSN/SSBN). Thus, between 2021 and 2025, the Asian giant launched 10 units compared to Washington’s seven, according to has discovered the IISS through satellite analysis of the Bohai shipyard in Huludao (northern China), as the epicenter of the industrial leap. In a decade, China has gone from being far behind to leading the race: Why is it important. This shift in underwater hegemony has three implications, one of which points directly to the US: Nuclear deterrence. The new submarines Type 094 and future Type 096 They expand China’s nuclear response capacity in the face of possible nuclear attacks. A preemptive attack is strategically unfeasible. Maritime control of commercial routes. SSGNs with high-speed missile systems add a layer of threat to foreign combat groups in the Indo-Pacific, complicating access for the US and its allies to potentially conflictive areas, such as the South China Sea or Taiwan. At a time when The United States is betting on boarding As a sign of maritime control, China has in this fleet a safeguard for its commercial routes. The United States cannot cope with that pace. John Phelan, US Secretary of the Navy, recognized in Congress that “All of our programs are a disaster, honestly. Our best-performing program is six months behind schedule and 57% over budget.” Phelan mentions the erosion of this industry, which according to the Government Accountability Office Today it faces problems such as aging infrastructure and a shortage of qualified labor. The surprise figures. The IISS Military Balance 2025 leaves other interesting figures to better diagnose the reality of both powers in nuclear submarines: Launch rate from 2021 to 2025: seven from the US to 10 from China. The difference in tonnage is notable: while those from China weigh 79,000 tons, those from the US are 55,500. Active nuclear fleet: The United States wins by a landslide, with 65 units compared to China’s 12 units (plus another 46 conventional ones). Quantity vs quality. We have already seen in the previous point that the United States continues to gain in numbers (still) and it is not the only reason for optimism for the country led by Trump. CNN echoes the IISS report where he explains that “Chinese designs are almost certainly behind American and European submarines in terms of quality.” Among other qualities, in noise: Chinese submarines are noisier, which makes them more vulnerable, they explain.

Now they are building a “highway” so it doesn’t happen again

by

Valencia will not be the same after DANA. The long reconstruction process has not yet finished and there is no shortage of key infrastructure so that citizens can regain normality and, if they suffer floods again, they will be less affected. An example: the new Quart de Poblet substation DANAs-proof to guarantee the electrical supply or the new pipelines of the La Presa (Manises) and El Realón (Picassent) water treatment plants so that no matter what happens, there is no shortage of drinking water. Context. Valencia and its metropolitan area drink from two rivers: the Júcar River (Picassent) and the Turia River (Manises) through their respective Drinking Water Treatment Stations with a high water network system. We are talking about the capital and approximately fifty municipalities, about 1.7 million inhabitants. Until before this canalization work, Valencia’s supply system operated in a compartmentalized manner, that is, the DWTPs were not interconnected. This represents a serious inconvenience: in the event of a failure in one plant (floods, breakdowns, lack of electricity supply) in one, the other does not have the physical capacity to divert flow to the affected sector. In short: there are parts of Valencia that are left without drinking water. Why is it important. Because this water highway project will ensure uninterrupted and proper supply to the metropolitan area of ​​Valencia. DANA tragically taught us that extreme climate events occur closer than we think and that we must get ready because we are going to see more of them: Spain should raise awareness of the culture of emergency. In this sense, a possible blackout or a flood is not a theoretical incident, but something that happens in reality: part of the metropolitan area of ​​Valencia he ran out of water those days. The work. To connect the two water treatment plants, 1,667 meters of pipe have been installed from the end of section I in urban Xirivella to the DN1600 pipe located in Valencia. The project is not new: it began in 2014 and will culminate in 2027 with a final section, which requires this 25-kilometer-long water highway with a large-caliber pipeline (1.4 meters in diameter) under the ground. The new channeling requires tunnels under the Turia River bed and other infrastructure, minimizing the surface impact on the Natural Park and the Orchard, a technical challenge of underground surgery in which the main pipes of the city will be connected, minimizing supply cuts. The total investment is 113 million, of which 13 will go only to this last section. A “smart” water highway. The achievement is not so much the implementation of this new network of pipes but the interconnectivity: now the water will be able to go where it is needed in an intelligent way, so that no one is left without supply, giving a new twist to the resilience of the facilities. From here, the ball is in the state of the Júcar and Turia rivers.

The US spent $600 billion building its highway network. It’s less than what big tech companies are going to spend on AI this year

by

The irruption of ChatGPT in the technological panorama in 2022 marked the starting signal in the AI ​​race; a race in which, year after year, large technology companies continue to increase their spending without stopping. 2026 has just begun and, far from letting it go, the big tech They have put their foot even further on the accelerator. All but one. walk or bust. We already know the planned capex for 2026 of the main technology companies, that is, what they plan to invest in capital expenditures. amazon: 200,000 million Alphabet: 175-185 billion Goal: 115-135 billion Microsoft: 140,000 million Apple: 13,000 million If we add it up taking the highest figures they have given, it is 673,000 million dollars, if we take the lowest figures it would be 643,000 million. In any case it is outrageous. In 2025 the figures were already dizzying and we are talking about an increase of around 60%. There has come a point where we have to stop and ask ourselves: How many zeros does that have? (yes twelve). Context of this madness. Here are a few comparisons to put this figure in context. It is superior to Sweden GDP in 2025 (662,000 million), that of Israel (610,000 million) and that of Singapore (574,000 million). As pointed out this user in Xexceeds what it cost to build the entire US interstate highway system (about 634,000 million) and is a quarter of the entire global military spending in a whole year. It’s like spending $1.2 million per minute for an entire year. It doesn’t make any sense. The market response. The fear of a bubble was noted after the announcements of the different companies, causing sharp falls in the stock market despite the fact that all of them have made profits (some breaking records). amazon fell 12% after announcing a capex of 200,000 millionmuch higher than forecasts Alphabet (Google) achieved record revenues, but it was not enough to convince the markets and its shares fell 10% in the following days Goal also announced record revenue and they had a 10% increase. However, days later things changed and they fell 8%. Microsoft fit the strongest blow, with a drop of 18%. Additionally, they revealed that 45% of their cloud business contracts are for OpenAI and the market does not reward dependency. Apple was the winner, with an increase of more than 7% since they announced results. The declines have been corrected in recent days and all companies have seen their value stabilize, but the message was clear: investors fear that this level of capex is far ahead of the ability of AI to generate profits in the short term. Where are they going to get the money from? It’s the big question. As stated in Financial Timescompanies must choose between reducing shareholder returns, using their cash reserves, or borrowing more money. In the case of Amazon, estimates point to a cash flow of 180 billion, Alphabet 195 billion and Meta 130 billion. The threat of free cash flow falling into negative territory is there, so we can expect them to issue more debt and stop share buybacks. Think different. Then we have Apple, which announced revenues of 144 billion in the last quarter, boosted by sales of the iPhone 17 during the Christmas campaign. Its capex is a fraction of what other companies have spent because Apple doesn’t build data centers, it outsources them. He agreement with Google to use Gemini can be interpreted as They have lost the AI ​​racebut in the context of a possible bubble it is a masterstroke: Google is the one who assumes the brutal spending on infrastructure and who is exposed to the bubble, while they benefit from their technology and see how the market rewards them for spending less.

more and more states are opposed to building them

by

The US is finding increasing resistance ahead of the construction of new data centers to feed AI, and New York has been the last state in joining it. Two Democratic legislators have presented a bill that would suspend the construction of new facilities in the state for three years, becoming the sixth territory to consider this type of measure in just a few weeks. Why is this happening? The bipartisan rejection of data centers has spread like wildfire across the country. In December, Bernie Sanders became the first national politician to ask for a general moratoriumarguing that it was necessary to “ensure that the benefits of technology work for everyone, not just the 1%.” Now, from Florida to Vermont, lawmakers from both parties are pushing for temporary pauses. According to Wired, more than 200 environmental organizations they signed a letter calling data center expansion “one of the biggest environmental and social threats of our generation.” In detail. The proposal, introduced by state Sen. Liz Krueger and Assemblywoman Anna Kelles, establishes a minimum three-year moratorium on issuing construction permits. During that period, the Department of Environmental Conservation and the Public Utilities Commission would evaluate the impact of these infrastructures to suggest new regulations. Just like share In the middle, the state currently has more than 130 data centers, and electricity demand linked to new projects has reached 10 gigawatts, triple what it was just a year ago. Among the developments underway is a 450-megawatt center built on a former coal plant. Where else is it happening. Georgia, Maryland, Oklahoma, Vermont and Virginia have also introduced bills this year to temporarily pause data center development. Although Georgia, Vermont and Virginia are Democratic initiatives, in Oklahoma and Maryland they have been led by Republicans. According to share Wired, as of late December at least 14 states had cities or counties that had suspended building permits. And Virginia, with more than 60 related bills introduced this year, has become the legislative epicenter of this battle. The hidden cost. data centers consume massive amounts of energy and waterand local communities fear an increase in your electric bills greater than what they have had to face until now. Just like account In New York, Gov. Kathy Hochul last month launched an initiative to force data centers to “pay their fair share.” “I don’t think there are many people who want to have higher energy bills just so some chatbot can corrupt a 13-year-old boy online,” declared Florida Governor Ron DeSantis. Resistance from below. Beyond the legislators, there is also citizen opposition that is pausing multimillion-dollar projects. According to Data Center Watch, between March and June 2025 they were delayed or canceled developments valued at 98 billion dollars. In Monterey Park, California, a six week campaign has achieved a 45-day moratorium and a commitment from the city council to explore a permanent ban. Between the lines. What is happening in the United States with data centers is a reflection of the problem that the evolution of AI brings with it: that it is generating a physical infrastructure the costs of which the communities where it is installed are not willing to assume. Many companies promise jobs with their construction, but once operational they hardly require personnel. They promise fiscal investment, but they skyrocket energy consumption and pollute with noise and emissions. A Morning Consult survey revealed that a majority of voters support banning the construction of data centers near where they live and believe they are partially responsible for rising electricity prices. And now what. The industry has begun to react. Just like share Wired, Microsoft presented last month, with support from the White House, a series of commitments to be a “good neighbor” in the communities where it builds. Dan Diorio, vice president of state policy for the Data Center Coalition, assured the outlet that the industry “recognizes the importance of continued efforts to better educate and inform the public about the industry.” The needs of Big Tech to advance their operations collide more than ever with public opinion, and it does not look like the gap is going to narrow anytime soon.

a 10-story building in 29 hours

by

There are those who think that a solution to housing problem is to build more (although the Polytechnic of Catalunya don’t think the same), but that inevitably takes time. Faced with this need, there are those who have resorted to the prefabricated housingwhose acquisition and assembly is more agile compared to traditional constructions. In fact, in Madrid They have already opted for them to build public flats quickly. But China is simply on another level. A skyscraper against the clock. Because if the work to remove the gotelé, change the floor and assemble the kitchen has cost me a long month in my new apartment, in the Asian country they are revolutionizing architecture with express constructions quite far from the modest prefabricated modules to which we are accustomed. However, in Changsha they have built a 10-story residential building in less than 29 hours. But don’t let the final result fool you: it is still a prefabricated construction. An XXL LEGO. This building of broad It is not new, in fact it dates back to 2021, but five years later it still leaves people speechless due to the synchronization and speed of execution. Furthermore, this project did turn out well, unlike the Sky City that he wanted to build in 90 days. Obviously having more personnel and the three cranes helps, but what is truly different is that we are dealing with a modular off-site construction. Come on, a large part of the work comes from the factory (the manufacturing there It was 15 days) and then it’s time to assemble the pieces. Moving a project of this magnitude to a factory has its advantages in that we are in a controlled environment and not out in the open. The Chinese company has been working on prefabricated steel structures for years. ISO size of a standard shipping container (12.19 meters x 2.44 meters x 3 meters), so they can be transported to the facility without problem by truck. In addition, they can be assembled in height and width as appropriate. The entire building could be dismantled for transportation if necessary. Their secret: B-core steel. These containers are manufactured in B-Core steelwhich consists of two outer stainless steel plates that wrap a core of steel tubes like a sandwich. The structure is joined by fusion by brazing with a copper sheet. In this video From Broad Group you can see the step by step of its manufacture. More important than the technical details is what is gained with this material. To begin with, the carbon footprint drops considerably by minimizing the use of cement (one of the biggest polluters on the planet), so we are facing a more sustainable construction. But it also offers high resistance to corrosion and since it has high ductility, it better supports seismic movements. According to the corporation, it is an earthquake- and typhoon-proof material. Finally, it is ten times lighter than concrete and assembly is faster, so costs, time and labor are reduced. Almost everything comes from the factory. The modules arrive by truck to the building construction site in standard trucks, the finishing and plumbing and electrical assembly already completed. There, the cranes are responsible for lifting them to place them exactly where previously planned, the walls and slabs are deployed in situ and finally, they are fixed with high-strength bolts. All that remains is to connect the supplies. The video is in timelapse. You don’t need it. The Broad group has documented the project in a video which looks like an authentic dance of synchronized choreography where the industrialization of the process on the one hand and the careful planning on the other show in fast motion a process that in real time was equally dizzying: three hours per floor.

It is now possible to book a hotel stay on the Moon for $250,000. Building it is still the complicated part

The Moon has returned to the center of the board and, this time, not only as a symbol of the past. The conversation is no longer just about missions and flags, but also what kind of activity could be sustained there if access becomes more frequent. On that horizon a broader idea begins to appear, that of a future lunar economy, with services and infrastructure yet to be invented. And among all these possibilities there is one that is disconcerting from the start: tourism, the promise of changing traditional vacations for a stay away from Earth. Landing the proposal. What has been put on the table is not a ticket or a travel date, but the option of entering into a process to reserve a future place in something that does not yet exist. GRU Space has opened an early access application program to participate in its first lunar missions, a pre-filter that, if passed, allows you to move to the deposit phase and maintain a position in the queue. There are still no assigned rooms or a closed calendar for guests, and the company presents the process as a way to select participants and check their ability to travel, not as a direct purchase of a stay on the Moon. Money rules. Booking is not cheap, nor is it definitive. The first step is a non-refundable $1,000 application fee. If the applicant is selected, GRU Space offers two deposit options, $250,000 or one million dollars, which can be recovered at any time from the first 30 days and which would be applied to the final price if the hotel accepts guests. That price, the company itself warns, has not yet been set and will probably exceed ten million dollars, a useful reminder that here the easy thing is to sign up and the difficult thing is to materialize the trip. A huge ambition with a minimal structure. GRU Space is, for now, a small company with a very big speech. Its founder, Skyler Chanrecently graduated from Berkeley and has explained that for much of 2025 he was practically the only full-time employee, a context that helps understand the early nature of this initiative. The company has secured seed funding, but its current scale does not correspond to that of a consolidated industrial organization. It rather fits a startup trying to turn a long-term vision into an executable plan. The Moon as a destination, not as a simple stop. In GRU Space’s approach there is a recurring idea: space transportation is necessary, but insufficient. The company defends that the bottleneck is in habitability, in having structures where people can stay without continually depending on the ship that took them there. Under this approach, the hotel is not presented only as a tourist whim, but as a use case that would force us to solve problems of daily life outside of Earth. His argument is that such learning, if it comes, would serve as a basis for broader infrastructures. The calendar that the company publishes is carefully staggered and full of conditionals. In 2026, it plans to review applications and profile the first participants, and then, in 2027, assign invitations linked to missions and stays through a selection mechanism and private bidding. The next milestone is in 2029, with the sending of a construction load to the lunar surface as a demonstration of preparation for subsequent phases. In its technical roadmap, the deployment of habitat and systems arrives in 2031 and the “first hotel”, as such, remains for 2032, leaving the tourist premiere for the end of a chain of steps that, on paper, should go well consecutively. From inflatable habitat to lunar construction. The project does not start with a permanent hotel, but with progressive technical demonstrations. GRU Space first proposes validating the deployment of inflatable structures and their behavior on the Moon, a way of testing without carrying the weight of a traditional construction from minute one. If that phase works, the next step would be to manufacture construction materials directly there, using the lunar soil itself as raw material, through geopolymer processes that, at least in their early stages, depend on activators brought from Earth. The idea is to reduce dependence on mass shipments and move towards more solid structures, designed for a more stable occupation. The target audience for GRU Space is not limited to the eccentric traveler with a huge bank account. In his approach, tourism acts as a catalyst for the broader economy, a way of introducing private clients into an environment dominated until now by state programs. The idea is that these first users help pay for infrastructure that can later be used for logistical, scientific or industrial activities. It is a bet to create demand where it does not yet exist, with the risk that the market will not materialize as they hope. The project leaves a clear feeling: the simple part is measuring interest and capturing early commitments, the complex part begins later. Turning an idea into functional infrastructure on the Moon means depending on launchers, technologies still in testing, and impeccable execution for years. In this context, talking about reserves serves to test the market, but it does not clear up the central doubts. The question is no longer whether there are people willing to pay, but whether everything else will arrive on time and as promised.
