The situation with RAM prices is so desperate that there are already those who build their own memory at home

by

The crisis we are experiencing with RAM memories and its exorbitant price is shaking the technology industry in multiple ways, precisely because they are components that found in the vast majority of devices that we use in our daily lives. Faced with the crazy prices, there are users who have not given up and have resorted to extreme solutions: building their own RAM memories. Untenable. Memory prices have skyrocketed to unsustainable levels. DDR5 modules that previously cost between 100 and 150 euros now easily exceed 350 euros in many markets. You can blame the AI. And the demand for DRAM for artificial intelligence applications has absorbed a large part of global production. OpenAI alone has accounted for 40% of all productionleaving home users paying the consequences. The worst thing is that it doesn’t look like this is going to be solved soon. And it is that according to analysis firm IDC, the shortage could last until 2027. cheap adapters. In recent weeks we have seen how some users have chosen to build their own RAM memories to face the price crisis. One of the approaches is to use SODIMM to UDIMM adapters. In a video The Hardware Canucks YouTube channel shows how they have tested this solution on Ryzen 7000, 9000, Intel LGA 1700 and LGA 1851 systems without too many problems. The approach is simple: buy DDR5 SODIMM modules (the ones for laptops) that are still relatively cheap and connect them to the system using adapters that cost between 10 and 15 euros. It must be said that this method also has its limitations, and that is that the data transfer speed that these adapters achieve is quite a lottery. In the tests carried out by Hardware Canucks they say that some do not exceed 4,800 MT/s stably, while others reach 5,600 MT/s or even 5,800 MT/s, although it depends a lot on the adapter model and the platform. In terms of performance, the good thing is that the difference is practically imperceptible. According to the content creator’s tests, with an RTX 5090 and a Ryzen 9800X3D, the difference is between 5 and 7% in the worst case compared to conventional DDR5-6000 memory. A more radical solution. Another approach is the one that the Russian modder VIK-on has opted for. And just as they count From Videocardz, the enthusiast has built a functional 32GB stick by combining chips from two 16GB SODIMM modules from SK Hynix, a Chinese PCB, and a heatsink from AliExpress. The total cost: 17,015 rubles, about $218. As explained in the media, in Russia an equivalent module costs at least three times more. Images: VIK-on After physically assembling the parts, a process that requires BGA reballing stations and considerable soldering experience, the modder then integrated ADATA firmware to enable an XMP profile that allowed the memory to run at a speed of 6,400 MT/s. In this way, VIK-on has achieved a functional 32 GB stick that any motherboard could recognize and that according to the modder works stably in games. Between the lines. That making a RAM from home is economically viable says a lot about the state of the market. Furthermore, not everyone experiences the situation in the same way, since in some markets such as Russia prices are especially prohibitive. Of course, soldering memory chips is not trivial, as it requires specialized equipment, technical experience and taking risks of damaging expensive components. The adapter method is much more bearable, but it is most likely that these homemade solutions will continue to be a niche. Most users will prefer to pay the extra price rather than risk soldering components or dealing with third-party adapters. Although if the forecasts end up being true and the crisis extends for several years, the emergence of a secondary market for professionally refurbished modules taking advantage of surpluses is no small feat. It would probably be the last solution we would resort to, but in other markets there might be enough demand.

The real reason why Musk, Bezos and Pichai want to build data centers in space: bypass regulation

by

The construction of data centers is proliferating so much that although the largest in the world They are in Kolos (Norway), in The Cidatel (United States) and China, you can find them now even in Botorritain the province of Zaragoza. The limit is the sky. Or well, not even that: because Silicon Valley has been put between eyebrows set up data centers in space. And the main big tech companies are making moves to achieve this. Former Google CEO Eric Schmidt bought rocket company Relativity Space with that objective. Nvidia has supported the startup Starcloud in its project to launch the first NVIDIA H100 GPU into space a few weeks ago and Elon Musk has even condensed how he would do it in a tweet: “It will be enough to scale the Starlink V3 satellites, which have high-speed laser links.” He when Jeff Bezos slipped it in a prediction at the Italian Tech Week: We will see “giant training clusters” of AI in orbit in the next 10 to 20 years. The moon is a gift from the universe The next question would be “why?”. The reality is that there is no shortage of reasons. AI is a real energy guzzler and as demand does not stop growingspace offers a couple of differential advantages over Earth: almost unlimited energy and free cooling. On the one hand, in space we have a sun-synchronous orbit where solar panels receive energy almost continuously. On the other hand, you can install a radiator so large that the space functions as a kind of ‘infinite heat sink at -270°C’. The enormous amounts of water essential for cooling on Earth would not be needed. Let’s face it, today there are no plans to have data centers in space. But not too far away: University of Central Florida research professor and former NASA member Phil Metzger esteem that perhaps within a decade it could be economically viable. But its viability is so clear that it considers that taking AI servers into space are “the first real business case that will give way to many more“in the face of a future human migration beyond Earth. So for now, they try it on Earth. Consequence: that Donald Trump declare an energy emergency due to the enormous electricity demand expected for the coming years. As the power grid catches up (or tries to), AI companies have decided to move from a passive to a proactive position: Meta is going to become an electricity marketer. xAI by Elon Musk is using gas turbines as energy sources temporary. OpenAI is pushing to the United States government to lend a hand to electricity companies to add 100 gigawatts per year. That figure doesn’t say much, but it is astronomical: what OpenAI is asking for is that The United States built almost an entire Spain (around 145 GWh considering the 129 GW consolidated at the end of 2024 plus the solar and wind deployment of 2025) every year and a half in terms of infrastructure. AI is growing faster than electrical bureaucracy is advancing How could the Trump Administration help? With the eternal bureaucracy. Because on Earth they face great technical challenges, but they also face a legislative wall. To have more energy, the simplest and most immediate step is to build new power plants, but that means successfully going through the tangle of procedures that slow down the process. There is only one small problem: that in the United States depending on technology, it can take five to ten years… if you’re lucky. Interconnection to the grid alone can take six years, successfully overcoming an interconnection queue with more than 2,000 GW in projects who are already in line. Then, up to four years of federal and environmental permits to end in another couple of years for state and local licenses that must come to fruition. ‘Permit Stack’ they call it. And the journey does not end here: they must also avoid andthe citizen movementNot in my backyard‘ (not in my backyard, kind of like “yes, but not in my house”), which has already backed down the Battle Born Solar Project (Nevada), which was going to be the largest solar plant in the United States, or Danskammer gas station (New York), among others. This can delay the operation even further as rights of way must be negotiated with individual owners who may refuse, going through the courts again. The never ending story. To avoid processes NIMBY that last fifteen years or more, companies like OpenAI or Microsoft are buying plants that already exist, such as Three Mile Island, which is going to reopen only for Microsoftinstead of trying to build new ones from scratch. Amazon has also signed infrastructure that is already on the network like the Talen Energy Campus and it has partnered with Dominion Energy and X-energy to develop mini reactors (SMR). SMRs are also Google’s solution, in this case thanks to an agreement with Kairos Power. Everything is to avoid that tangle of ‘Permit stack’ procedures that in practice and according to estimates, makes it is faster to opt for the space route to build a power plant on the old, familiar Earth. At the end of the day for AI companies “The moon is a gift from the universe”, as already Jeff Bezos glimpsed.

A British MP did not have permission to build a house in the countryside so he was left with only one option: dig it up

by

Housing is one of the main problemsnot only because of the scarcity that makes its price skyrocketsbut because, even if you already have a plot on which to build the house of your dreams, urban planning and environmental legislation will not always allow you to build it. That is precisely what happened to British MP Bob Marshall-Andrews in the late 90s, when he wanted to build a house with sea views in Wales, but faced a huge dilemma. Environmental regulations did not allow him to erect any buildings since it was a natural space. There was only one way out so that your home was legal: dig it out. A house in a hole with sea views As and how did he count Wales Onlinelawyer and Labor Party MP Bob Marshall-Andrews and his wife Gill wanted to escape the bustle of the city and enjoy the leisurely pace of the waves crashing into St. Bride’s Bay on the Pembrokeshire cliffs in the far west of Wales. For years, he and his family had been spending vacations in an old military barracks. on Druidston Cliffuntil the structure began to deteriorate and the need to build something new became apparent. That’s where his problems began. The land of the MP and his wife Gill is located about 150 meters from the sea, in the heart of the Pembrokeshire Coast National Park, a protected area since 1949 that covers more than 300 kilometers of coastline with cliffs, open beaches, sheltered bays, marshes and dunes. In this environment, the authorities have been traditionally very strict: the neighbors considered practically impossible to obtain permission even for small glazed extensions in existing houses. To comply with the regulations and still stay in that place, the only way was to literally hide the new house underground, excavating the land and taking advantage of the natural ridge of the cliff as part of the construction. The idea came from his son Tom, who thought it would be a good idea to integrate the house into the landscape by excavating it between two hills. The result was Malatora semi-buried house, almost invisible from afar, which today has become one of the most striking examples of architecture integrated into the landscape of the Welsh coast. So much so that it even has your own reference on Wikipedia. A crazy idea that ended in genius The British parliamentarian left the commission to the architects Jan Kaplicky and Amanda Levetefounders of the Future Systems studio, had a central premise: to obtain legalized housing that would not give arguments to those responsible for the park. to deny license. To avoid any feeling of privilege towards a parliamentarian, the project was planned from the beginning as a construction that would not compete with the landscape, but would hide in it and reduce its visible impact to a minimum, just as Tom, the son of the owners, had proposed. Thus, the architects chose build downexcavating the hill instead of raising a traditional construction, so that the house will be buried under a cover of earth and grass that continues the shape of the hill. This strategy is reminiscent of ancient techniques from northern Scandinavia, where layers of earth and grass were accumulated to form thick walls with good thermal inertia and great camouflage capacity in the terrain. The designers were inspired by the wing section of an airplane for its visible part. The façade facing the sea is resolved with a large glass plane and portholes, while the upper part and sides are buried and covered with grass and vegetation, so that from the park path the house is perceived as a simple mound covered with grass. This extreme integration with the landscape It was decisive for the local authorities to give their approval, since the construction does not break the undulating line of meadows and bushes nor does it introduce visible plot limits, fences or gardens separated from the rest of the park. Furthermore, technically, no construction had been “raised”. Inside, the curved floor plan is organized around a central fireplace, inspired by the great medieval halls. A large semicircular sofa and prefabricated walls that separate the rooms of the house without touching the ceiling, reinforcing the feeling of continuous space. Respect for the environment was taken to the extreme even during its construction, as many of the internal elements, including the bathrooms, were manufactured in workshops and brought in small pieces to the plot. A decision designed to reduce heavy truck traffic to a minimum on a narrow road adapted to the orography of the cliff. The house soon became popular in the area and, given its peculiar design, the locals have baptized it as “the Teletubbies house” due to its resemblance to the half-buried house from the children’s series, a nickname that its owner receives with humor.

Ryanair thought it could build loyalty with a subscription service. Until you’ve remembered what your real business is

by

“It has cost more money than it generates” With a brief note and the statements of Dara Brady, CMO of the company, Ryanair has confirmed the closure of Prime, the membership program that sought to retain its customers with advantages that have generated greater costs for the company than benefits. The subscription service of the company has not lasted even a year before its cancellation. Surgical. A test, some results eight months later and a decision: close Prime. Ryanair has confirmed that it is closing its subscription program just eight months after it was launched on the market in a decision that is as firm as it is clean. Subscribers will maintain their benefits but those who had not signed up until last Friday, the 28th, will now no longer be able to do so. They report on the company’s website that customers will maintain their benefits “of exclusive savings on flights and seats for the remaining 12 months of membership.” However, the company’s Prime program already has its days numbered. two million. It doesn’t seem like much for a company like Ryanair, but it speaks volumes about the rigorous cost control that the company manages. The statement includes the words of Dara Brady, CMO of Ryanair, who points out that the program has collected 4.4 million euros in subscriptions but that the benefits delivered are greater than six million euros. That is, in the eight months in which the service has been active, the company has lost less than 250,000 euros per month in the new program. Doesn’t seem like much for a company that has obtained 2,540 million euros in the first quarter of 2025. What did they offer? In its announcement last March, Ryanair offered the following benefits For your subscribers: Priority sale on selected flights Exclusive discounts for some flights Free seat selection for the member and one companion To access these benefits, the client had to pay 79 euros per year. According to the company’s accounts, seat selection alone already amortized the investment from three flights a year. With four flights made per year, we would be amortizing 26 euros on average. The subscription extended for a maximum of one year or 12 flights per year. In addition, I had travel insurance to cancel flights due to injuries or illnesses, the delay of other flights or theft of luggage. Of course, those over 70 years of age were excluded from sickness coverage. Unattractive. “With more than 207 million passengers this year, Ryanair will remain focused on offering the lowest fares in Europe to all our customers, and not just this group of 55,000 Prime members.” The closing of the press release published by the company is a clear confirmation of what happened. The most attractive thing that Prime offered was that the customer could choose (and save money) in the choice of seats but it did not even guarantee that two passengers (one being “non-Prime”) could travel together. It is an incentive that has not been attractive enough for a company where the customer looks for the cheapest way to travel and chooses to add services little by little, depending on how much money you are willing to pay. Nothing premium. Ryanair’s test has convinced the company that it has no room to delve into policies that bring it closer to premium or higher-cost companies. Many of the airlines with higher prices offer cards or loyalty services to keep their customers retained, but this way of acting has not caught on among the Irish company’s customers. The reasons are obvious. When someone chooses Ryanair it is because they expect the lowest possible price for a short flight. And you are willing to sacrifice by traveling with less luggage or accepting 100% digital boarding. You either take it or leave it. And Ryanair knows that the customer will leave it when the competition offers that same flight at a cheaper price. On the other hand, customers who are loyal to higher-cost companies obtain other advantages that do receive greater attention on flights of higher cost and time. For example, loyalty cards companies like Iberia They allow access to VIP lounges or priority boarding, secondary values ​​for those who aspire to travel through Europe at the lowest possible price. To this we must add that the high price paid for the ticket ends up subsidizing these companies for the economic effort they have to make to deliver the benefits to their customers.

Spain has never been a land of skyscrapers. Now someone wants to build one for luxury tourists in Malaga

by

Malaga is known for the Alcazaba, Gibralfaro or its Cathedral. If Hesperia and the Qatari fund Al Alfia manage to move forward with their plans, in not too long it will also be for another building, one that will also mark their skyline: the Port Tower. The project is not new (it has years on the table) and has generated considerable controversy in the city, but its promoters have just made it clear that they are not giving up: after receiving green light of the Port, the companies that are trying to move it forward have organized an event to share dates, data and investments. Their objective is to demonstrate that they are still committed to building a 144-meter tower in a country, Spain, that stands out for its little hobby by the skyscrapers. What is the Port Tower? A megaproject which has been in the offices of administrations for almost a decade and (above all) generating debate in Malaga. And the “mega” thing is more than justified in this case. At least if we pay attention to the latest data broken down by their promoters. The idea is to build a skyscraper 144 meters high, 59 meters wide and 19 meters wide at the end of the Levante dock, in the middle of the port, near the maritime station where the cruise ships dock. The tower will act as a huge hotel 382 roomsbut its promoters they insist in which it will arrive accompanied by a much more ambitious and useful infrastructure for the city that will cover, in total, 54,000 square meters. “The hotel will be located in a currently depressed area, where there is nothing, and we are going to recover that environment for the city and the citizens,” slide from Hesperia, a fundamental piece in its promotion together with the Qatari fund Al Alfia. Is more information known? Yes. Both about the hotel itself and the urban development that will accompany it. The icing on the cake will be the skyscraper: 144 meters high whose centerpiece will be accommodation focused on the high-net-worth clientele that comes to Malaga. The objective, in fact, is for it to operate as a five-star Grand Luxury hotel and be managed by an international chain (there are already interested parties). Beyond the hotel, the complex will include a 2,500 m2 auditorium, underground parking, a restaurant, a plaza and a 1.3 km boulevard with viewpoints, a bike path, green areas… The development companies in fact calculate that the complex will cover around 54,000 m2. “It is not a speculative project, it will have a return for the developer, but above all for the city because it creates many public spaces,” investors claim in The Opinion of Malaga. How much will it cost? There is talk of an investment of about 200 million eurosalthough initially the figure was quite inferior. This high amount (along with the special status of the land) explains why the promoters insist on the “transformative” and social dimension of the project and the return it will have for Malaga. The reason? To begin with because the promoters they do not rule out qualify for European funds and have support from the administrations. Before even thinking about financing, the project must nevertheless get its future cleared by the Council of Ministers, for which it is key that its public utility be demonstrated. Why is it news? The initiative is by no means new. A quick search in the newspaper archive arrives to verify that he has been chaining procedures for years, a complex path during which he even changed his star architect: the Valencian José Seguí He moved not long ago to the Londoner David Chipperfielwinner of the Pritzker Prize (the Nobel Prize for architects) in 2023. In recent weeks, however, the tower has been in the news again for two reasons. The first came in October, when the Port Authority gave the green light to the complex and allowed him to move on to the next stop in his processing: the State Ports table. There they must study it in depth before it reaches the Council of Ministers, which must rule on whether the hotel complex fits into the Levante dike. That is, whether or not it authorizes the hotel use of that space. The second reason why the tower is being talked about these days is because its promoters, Hesperia and Al Alfia, have organized an act to emphasize that they are not giving up. In fact, the quote served to explain details of the Chipperfield project and outline the schedule managed by the companies: their objective is to resolve the pending issues “in the medium term” to start the works as early as 2026. According to their estimates, the work will last about three years. Will that be possible? First, the project must overcome certain obstacles. And not all of them have to do with financing. The project needs the green light from the Council of Ministers and Óscar Puente, Minister of Transportation, since has warned that the Executive will not move until it knows the judicial resolution to the appeals presented by the Defendamos Nuestro Horizonte platform and the Academy of Fine Arts of San Telmo, critical of some aspects of the project. They are not the only ones. ICOMOS, linked to UNESCO, has warned also the landscape impact of the tower. Spain, country of skyscrapers? Although in Spain there are skyscrapers like the Crystal Towerin Madrid, of 249 m, and in Andalusia itself we find the Seville Tower (180.5 m), the truth is that our country does not exactly stand out for its large buildings. Some time ago Skyscrapercenter made a ranking with the nations with the highest number of towers that exceed 150 meters and Spain occupies 32nd place, behind other European countries, such as Germany, France or the United Kingdom. The Malaga tower is a reminder of one of the controversies generated by this type of structures: its impact on the landscape … Read more

Saudi Arabia is looking for someone to build its new high-speed train. And a battalion of Spanish giants are going to compete

by

Saudi Arabia has put one of the most ambitious railway projects in the Middle East on the table, and the response from the global industry has been especially strong: 145 international companies have officially expressed their interest for participating in the new high-speed line that will connect Riyadh with Qiddiya, a newly created city dedicated to tourism and entertainment. And as it could not be otherwise, among the candidates stand out several Spanish companies with great experience when it comes to cooperating in Saudi projects. What exactly is this project. It is about the Qiddiya High-Speed ​​Railalso known as Q-Express, a high-speed rail line that will link King Salman International Airport and the King Abdullah Financial District (KAFD) in Riyadh with Qiddiya City, according to the Royal Commission for Riyadh City (RCRC). The trains will reach speeds of up to 250 km/h and the intention is for them to complete the journey in about 30 minutes. Qiddiya is one of Saudi Arabia’s five official mass tourism-oriented gigaprojects and is expected to occupy some 376 square kilometers. The city will include 12 amusement parksa Formula 1 circuit and is projected to house 500,000 inhabitants. Several Spanish companies interested. Between companies that have shown interest There are Spanish names with weight in the railway sector. CAF and Talgo appear in the category of manufacturers of rolling stock and railway systems, where they compete with giants such as Alstom, Siemens Mobility, Hitachi Rail or Stadler Rail. Renfe and Alsa, for their part, are among the 12 interested railway operators, along with Deutsche Bahn, Ferrovie dello Stato Italiane or SNCF. In construction, FCC Construction and Copasa stand out, while in technical consulting, Sener, Ayesa, Idom and Typsa are present, competing with international firms such as Aecom, AtkinsRéalis or Systra. Previous experience in the country. Several of these Spanish companies are not new to Saudi Arabia. Some were part of the consortium that developed the well-known AVE to Mecca (Haramain train), which connects the holy cities of Mecca and Medina. Currently, Renfe operates precisely that high-speed line. The president of the company, Álvaro Fernández de Heredia, visited Saudi Arabia just a few weeks ago to participate in an international railway meeting, and where reaffirmed the company’s commitment to collaborate with Saudi Arabia Railways on new projects. For its part, Alsa It already has a guaranteed presence in Qiddiya: a €500 million contract was recently awarded to operate the city’s future buses. Fierce world-class competition. He complete list of interested parties gives clues to the magnitude of the project. The 68 main contractors include companies from China (eight companies, including China Railway Construction Corporation and Aviation Industry Corporation of China), Turkey (with Gülermak, Kalyon or Yapı Merkezi), Italy (Webuild and Saipem), South Korea (Hyundai Engineering and Samsung C&T), France (Bouygues Travaux Publics), India (Larsen & Toubro) and Portugal (Mota-Engil), among other countries. 16 capital investors and 23 design and project management consultancies have also shown interest. How it is going to develop. The project will be executed under a public-private partnership model (PPP), as announced by the RCRC in collaboration with the National Center for Privatization and the QIC. The registration period where companies could show interest in the project opened on September 12 and closed on October 12. Although it was initially planned to be developed under a conventional model, the Saudi authorities finally opted for a public-private collaboration scheme. What comes next. The development includes two phases. The first will connect Qiddiya with KAFD and King Khalid International Airport. The second phase will extend from a development known as North Pole, which includes the Public Investment Fund’s two-kilometre-high tower, to New Murabba, King Salman Park, central Riyadh and the Industrial City south of Riyadh. In addition, the 65-kilometer Riyadh metro line 7 will also connect the capital with Qiddiya City in the future. With so many high-level companies competing for this megaproject, now it’s time to find out which consortiums manage to position themselves as favorites in the bidding.

If the solution to the housing crisis in Madrid is to build, there is a municipality that has taken the lead: Alcobendas

by

Madrid begins the countdown to have a new and large pool of apartments in the north, relevant news if you take into account how tense its market is and the serious deficit of housing that drags. The Alcobendas City Council has just given green light to the partial plan of the new neighborhood of Los Carriles-Valgrande, a new (and enormous) area of ​​​​the town that will have around 8,600 homesa good part of them (more than 4,600) protected. We will still have to wait before seeing the new blocks built, but its promoters are already anticipating that it will be “the largest urban development project in the north of Madrid”, with a wide range of residential, services and parks. What has happened? That Madrid is a little closer to reinforcing its residential offer with an injection of 8,600 homesa good part of them under protected regime. And that is always news in a market like the capital, marked by the price escalation (both in sales and rentals), certain access conditions each time more draconian and the imbalance between supply and demand. In fact in one of his latest reports The Association of Real Estate Developers of Madrid (Asprima) states that to meet the demand of the community it is necessary to create 40,000 homes per yearwell above the volume of new construction that is being generated right now. As a reference, remember that last year “a maximum peak” of 23,500 homes was delivered and everything indicates that the pace of completions will not reach that mark in the coming years either. Where will they be built? These 8,600 new homes will be built in Los Carriles-Valgrandea new (and ambitious) neighborhood planned in the municipality of Alcobendas. The initiative is interesting for several reasons. In addition to reinforcing the offer, its promoters they boast that it will be “the largest urban project” in the north of the community and one of the developments “with the highest proportion of affordable housing.” In addition, it will “complete” Alcobendas up to its limit with the capital. The new buildings will arrive accompanied by hectares of green areas, two new parks and more than 55,000 m2 dedicated to the tertiary and commercial sector. Its implementation will also generate employment: Alcobendas City Council speaks of 4,000 positions during construction and more than a thousand once the neighborhood is completed. In terms of mobilized capital, it is estimated that the investment will be around 2,300 million euros and the return for the municipality will be around 511 million. Do you know anything else? Yes. Of the 8,600 homes that will be built, around 4,600 (54%) will be protected and 40% will be built on municipal plots. The project also includes the creation of 570,000 square meters of green areas and open spaces, which will include two new and large parks, one next to Monte de Valdelatas and another near the Valdelacasa stream. “Each one will have dimensions that are equivalent to six times the Andalusia parkin Alcobendas”, they need the promoters of the project, who remember that all trees that are affected by the urbanization will be replaced. In fact, they estimate that the area will go from having 2,555 to more than 6,700. He dossier The urban planning area specifies that in total it will occupy about 2.17 million square meters, of which about 57% will be public surface. 25% will be dedicated to green areas and almost 20% to equipment and services. Once it goes ahead, its promoters estimate that it will be able to accommodate around 25,800 inhabitants, a considerable population injection for the area if one takes into account that right now Alcobendas has (according to the INE) 121,400 registered. Why is it news? The project is not new. In fact, Leopoldo Arnaiz, manager of the Valgrande compensation board, remember that there are people who have been working on it for more than 20 years. If it is news now it is because it has just overcome a key obstacle at a bureaucratic level: on Tuesday the local plenary session of Alcobendas gave the green light to the new partial plan, which will allow further progress in the processing of the urbanization. The approval has also been majority: the plan went ahead with the favorable photo of 26 of the 27 councilors of the corporation. “With the approval of the new partial plan we offer legal security for buyers, investors and to continue with the urbanization project in the area and maintain the action schedule,” stands out the mayor of the town, Rocío García Alcántara. Among other issues, the document details the distribution of homes, public spaces and parks, marks the location and layout of roads and what land will be reserved, for example, for green areas. And from now on? The step is also important because it helps urbanization overcome the legal obstacles those he had encountered. In his day the Supreme delayed it due to a technical defect after noticing a failure in the strategic environmental evaluation of an artificial mountain. Once the urbanization works allow it, the idea is to start the work to build blocks and have the first homes “as soon as possible”although the Consistory does not specify dates. “The final approval of the partial plan is great news,” claims Arnaiz. “Today we take a decisive step. We continue to advance and comply with the roadmap that we announced in June. And we reaffirm our commitment to this development, because it is viable, sustainable and necessary, since it responds to a real demand from the residents of the municipality and the north of Madrid.” Images | Valgrande and Alcobendas City Council In Xataka | Madrid needs to decentralize its tourism if it does not want to suffocate.

The world keeps asking for more F-35 fighters, but China has turned off the tap to build them

by

He F-35 Lightning IIthe fighter more expensive and complex never built, is going through a critical point in its history. In September 2025, a report of the United States Government Accountability Office (GAO) revealed that all deliveries in 2024 arrived late, accumulating an average of 238 days late. Now, a leak has revealed that delays can multiply, and China plays a fundamental role. The problem of the largest military program. They remembered a few months ago on Insider that the 2024 delays had one main cause: the stagnation of the Technology Refresh 3 technology package (TR-3), an essential hardware and software update on which the block 4 modernizationalready with an extra cost of 6,000 million dollars and five years behind schedule. The paradox was that, despite maintenance failures, deficiencies in availability and costs that already exceed 2 trillion dollars Throughout its service life, the F-35 remains the cornerstone of American and allied air defense. More than 2,500 units remain in the Pentagon’s planning, while the current fleet is barely “operational” half of the time. More money. Lockheed Martin, its prime contractor, continues to receive incentives even for late deliveriesin a program that no longer only faces technical delays, but a much more structural threat: global dependence on its supply chain. A global network. The F-35 is, by definition, a multinational aircraft. Of the more than 1,200 devices manufactured to date, about 42% of its components are produced outside the United States, in an industrial network that involves more than twenty countries. The United Kingdom, the only Tier 1 partner, manufactures in Lancashire the rear fuselages of all the F-35s in the world, as well as their tails, ejection seats and part of the electronic warfare system code. Italy and the Netherlands assemble structures and optical systems, while Australia, Canada, Norway or Denmark provide fuselage sections, wings or specialized electronics. Germany, Japan and Israel also contribute critical parts: from fuel tanks to helmet-mounted visors. This ecosystem, which combines thousands of suppliers under a single oversight, has made the F-35 the largest industrial cooperation project of defense of the planet. The small print. But, despite the geographical dispersion, total control The United States preserves it: the Department of Defense and Lockheed Martin jealously guard it the source codemaintenance keys, stealth algorithms and the ALIS logistics system, without which no country can operate the aircraft independently. Each export includes clauses that maneuvers are prohibited joint with Russian or Chinese systems and allow Washington to supervise every flight, every review and every software update. You hunt like hotcakes. By 2025, Lockheed Martin has opted to reverse the narrative of delays with a figure that reflects both ambition and vulnerability: manufacturing 200 fighters in a single yearone for each working day. In its third quarter earnings call, CEO Jim Taiclet announced that 143 units had already been delivered, with an order book valued at 179 billion dollars, the largest in the company’s history. The boom responds to the global increase in defense spending, with European countries accelerating its rearmament and new buyers (such as Finland or Japan) incorporating the F-35 as the central axis of their fleets. The plane has become a tool deterrence and cohesion between allies, a symbol of interoperability under the umbrella of Washington. But industrial success hides a strategic fragility: the complex network of components of the F-35 depends, directly or indirectly, on materials that almost entirely come from Chinafrom rare earth magnets to elements for critical sensors, servomotors and actuators. Beijing’s silent weapon. Through a Wall Street Journal exclusive We have learned that, while Lockheed Martin celebrated its best year for deliveries, China moved its own parts with surgical precision. Beijing announced the creation of a system of “validated end users” (VEU) to regulate the export of magnets and rare earth metals: essential materials for both F-35 fighters and submarines, drones or electric vehicles. The plan, presented as a measure of trade opening after the tariff truce between Xi Jinping and Donald Trump, in reality aims to exclude any company from the flow of exports. linked to the military complex United States. In other words, the companies that supply the F-35 (from engine manufacturers to aerospace subcontractors) will be blocked, while supplies to civilian industries are prioritized. Strategic deterrence. With this system, Beijing can formally fulfill its promise of liberalize tradewhile suffocating the critical chains of the North American defense sector. The VEU architecture, inspired by the United States’ own export control mechanisms, turns industrial policy into a deterrent instrument strategic. The bottleneck. Chinese control over rare earths (70% of the extraction and more than 90% of the world’s processing) places Washington before a structural dilemma: Your most advanced hunting depends on a monopolized resource by its main geopolitical rival. Although the White House seeks to diversify sources through agreements with countries such as Kazakhstan, Greenland or Ukraine, replacing Chinese capacity will take years. In recent months, Chinese magnet exports to the United States fell 29%which has already begun to affect engine and guidance system manufacturers. If Beijing strictly implements its new system, it would not only slow down F-35 production, but could temporarily interrupt the logistics chain for maintaining fleets already deployed. In that scenario, the program that symbolizes Western technological supremacy would be conditioned by dependence on a strategic enemy. The paradox of a fighter. The F-35 was born as an emblem of interoperability and technological masterybut its evolution shows that military superiority is no longer measured only in radars or missiles, but also in access to mineralschips and advanced materials. As the world’s most expensive plane is assembled from parts manufactured on three continents and with magnets processed in China, its story becomes a metaphor for the 21st century: a war of interdependencies where each fighter that takes off carries within it a dose of global vulnerability. Thus, while Lockheed Martin tries to maintain its record pace of production and the Pentagon reinforces its leadership narrative, the real battlefield is being fought in the mines, laboratories … Read more

build 2,000 apartments on top of other houses

by

The Basque Country wants more public housing. Quite a bit more. And you already know how to get it without having to go through cumbersome bureaucratic procedures that take forever in the offices. The Department of Housing and Urban Agenda just announced which will triple its current supply of accommodation, expanding the height of 65 VPO buildings that already exist. That is, to the current 937 apartments (and 253 under construction) another 2,000 will be added that They will ‘sprout’ on the roofs. To achieve this, it will rely on construction with wood and modular parts. What has happened? That the Basque Country has found a formula to reinforce its public housing stock in an agile and fast way, without the need for complex administrative procedures that would lengthen the deadlines. The announcement was made this week by the Minister of Housing and Urban Agenda, Denis Itxaso, who explained that what the Basque Government is considering doing is building new apartments on the roofs of public buildings that are already built. To be more precise, the Executive has set its sights on 65 properties in which, it estimates, it will be able to build 2,000 accommodations. What exactly do you want to do? Gain endowment housingflats built on public land and which usually offer temporary accommodation to vulnerable people. Right now the Basque Executive has 937 in use and another 253 under construction. Its objective is to boost this supply with 2,000 new homes spread over the roofs of 65 public blocks already built. It is not just theory or a statement of intentions in the medium or long term. The Department of Housing and Urban Agenda is working on six pilot projects that will allow it to create between 210 and 250 new accommodations (about 10% of all those planned) for temporary and rotating rentals, housing designed especially for young people who have just emancipated themselves and are looking for employment. Of these actions, two are distributed in Vitoria-Gasteiz, another two in Bizkaia (more specifically in Bilbao) and the remaining two in Gipuzkoa. The measure has been adopted after technicians have confirmed that in “most” of the public rental buildings with flat roofs it is “viable” to add heights. “In most cases around two floors set back.” Why is it important? Because it opens a quick and agile way to expand the housing supply, a message that the Basque Government has been responsible for underlining. The formula, however, is designed for a very specific type of housing: public and for rotational rental. “These residential units, being considered residential equipment, do not increase urban buildability and, therefore, can be undertaken without the need to modify the general planning,” clarify. How is it possible? The project is contemplated in the Law on Urgent Measures for Housing, Land and Urban Planninga legal framework that is already being processed in the Basque Parliament. “The new rule provides that these lifts can be carried out through a detailed study, the processing of which is simpler and more agile than the approval of a special plan, as is currently required,” Itxaso clarified during his speech at the Regional Chamber, where he spoke of “a novel way.” “In short, it is an initiative that will allow us, without consuming land or modifying planning, to triple the number of public accommodations. Two thousand new accommodations for young people will be possible thanks to the reforms introduced by the Law on Urgent Measures for Housing, Land and Urban Planning”, the leader insistswho claims that the commitment “combines innovation, sustainability, social cohesion and effectiveness in the public response to the challenge of access to housing.” Do you know anything else? Yes. Beyond the regulatory framework, the figures and the selection of the first properties in the program, the Basque Government has explained how it plans to build its new endowment offer. It will opt for industrialized housing, a formula that the Executive has stood out already in the past. “We have opened a line of collaboration with the kabian projectlinked to social initiative cooperatives, which proposes a light and modular construction system in wood” explains Itxaso, who trusts that the use of industrialized techniques will allow “reducing costs, execution times and impact on the environment.” And beyond Euskadi? The Basque Country is not the only one that has looked at the roofs of buildings to gain housing. At least with a social focus. A few months ago the PSPV proposed in the Urban Planning Commission of the Valencia City Council to touch up the local planning so that the buildings could grow taller to add public housing. The plan did not prosper, but according to the calculations of the socialists it would allow the construction of more than 70,000 protected apartments. The height and the possibility of reinforcing the housing supply have also been raised in other large cities, such as Palm, Madrid or Barcelona, ​​where they have granted licenses to increase the buildability of existing blocks.

Spain no longer knows what to do with its surplus of renewables. So he is going to build a huge electric bridge with Ireland

by

Spain shines with sun and wind, but is drowning in its own green electricity. Solar and wind farms break generation recordsbut a good part of that energy is wasted due to lack of network, storage and connections with Europe. While the country operates in “reinforced mode”has found a possible solution to dispose of its renewable surplus. An electric bridge. On this path of releasing its excess energy, Spain has found in Ireland the best matches to connect. Irish Minister for Climate, Energy and Environment, Darragh O’Brien, advertisement After a meeting with the Spanish Secretary of State Joan Groizard, both countries are working on the construction of an underwater electrical interconnector between Ireland and Spain. Speaking to RTÉ NewsIrish Minister Darragh O’Brien announced that the project will seek to be co-financed with European funds and be completed in the mid-2030s. It will not be a minor project: the cable, he explained, will allow the buying and selling of electricity between both countries, balancing generation peaks. O’Brien acknowledged that, for now, “Spain is more likely to export energy to Ireland,” because the country usually has a surplus of renewable power that it cannot always take advantage of. We’re going to a wedding. The idea of ​​joining Spain and Ireland with an electric cable may sound eccentric, but it responds to continental logic: countries that produce green energy need to sell it, and those that are isolated need to receive it. In this context, our country is a clear example of the first group. The country has one of the largest renewable capacities in Europe —more than 40GW new since 2019—, but its level of international interconnection it barely reaches 2.8%well below the European target of 15% set for 2030. On the other hand, Ireland belongs to the second group. Its system depends almost entirely on the United Kingdom and France, and the country is, along with Spain and Finland, among the most exposed to blackouts due to lack of interconnections. according to a study by the consulting firm Ember. The analysis warns that 55% of the European electricity system has limits on importing electricity, which increases the risk of supply failures. How will the new cable work? It will be a high-voltage underwater interconnector (HVDC), the same system already used to move clean electricity over long distances between countries. The project is inspired by the Celtic Interconnectorthe Ireland-France link that will open in 2027, and will allow gigawatts of renewable energy to be transported under the Atlantic. There is still no closed route, but the Bay of Biscay appears as the most likely option: there it is already another cable advances between Spain and France, co-financed by the European Investment Bank. The political objective is clear: integrate the networks of the European periphery into an interconnected continental system, less vulnerable to blackouts and more efficient in the use of green energy. Furthermore, both countries recently led a meeting in Luxembourg of the “Friends of Renewables” group, together with 15 Member States and the European Commission. At that meeting, the new European Electricity Grids Package was presented, considered “one of the key pillars to facilitate affordable, safe and clean renewable energy.” Everything starts from the cables. The challenge is not only in producing more, but in transporting and storing energy. Spain invest only 30 cents in the network For every euro allocated to renewables, half of the European average. In this way, the cable with Ireland would fit into a map of projects that aims to break the energy isolation of the Iberian Peninsula. In addition to the Bay of Biscay link, are underway the Navarra–Landes and Aragón–Marsillón connections with France, a third interconnection with Morocco and new links between islands and the continent. If all these cables materialize, Spain will go from being “an energy island” to becoming an energy node between Europe and Africa, capable of exporting its renewable surpluses at competitive prices. The next great leap in European energy could start here: an electrical wire under the sea that connects the Spanish sun with Irish houses.
