salvation

The Canary Islands have been suffering total blackouts for years. Their salvation is a beast of engineering 1,145 meters under the sea

by

A month ago, the destabilization of an old generator at the El Palmar thermal power plant in La Gomera caused a dramatic “cascade effect” that left more than 15,000 people without electricity, and without mobile coverage. This incident showed the extreme fragility from living in an isolated electrical system. However, the solution to this historical vulnerability no longer looks to the sky, but to the depths of the Atlantic. To overcome the abrupt volcanic orography and the extreme pressures of the Canary Islands seabed, engineering has had to design an “umbilical cord” unprecedented in the world, marking a before and after in the history of the archipelago. The end of isolation. In an effort to protect supply, Red Eléctrica de España (REE) has officially inaugurated the underwater interconnection between La Gomera and Tenerife. As confirmed by the REE itselfthe magnitude of the project translates into historic figures: an investment of 145 million euros for the cable laying, to which are added another 32 million destined for the two link substations located in Chío (Tenerife) and El Palmar (La Gomera). It is not a capricious work. How they collect local mediathe Canary Islands have suffered nine major “energy zeros” (total blackouts) since 2009. Tenerife and La Gomera have been among the islands hardest hit, so this infrastructure was born as a vital antidote to darkness. More than light. The implementation of this system completely alters the energy paradigm. As indicated ANDldiario.esboth islands cease to be solitary island systems and become a single network. From now on, if the rubber plant fails, Tenerife will inject energy instantly to avoid a blackout, and vice versa. But the scope of the work transcends mere security. As explained in detail in the REE statementcable is the key to decarbonization. La Gomera will now be able to generate much more renewable energy – mainly wind – than its population consumes. This green surplus will not be lost, but will travel along the seabed to Tenerife, drastically reducing the burning of fossil fuels on both shores. The technical challenge: engineering to the limit. Connecting two volcanic islands separated by abyssal trenches is not an easy task. As emphasized The Daythe 36 kilometer length of the cable descends to 1,145 meters below sea level. This extreme depth makes it the deepest tripolar alternating current link on the entire planet, snatching the record that linked Crete and the Peloponnese since 2021. To withstand the weight and crushing pressure of the ocean at these levels, engineering had to reinvent itself. To do this, they had to discard the traditional use of steel and lead, opting instead for an ultralight synthetic material armor and an insulation based on ethylene and propylene rubber. Caring for the environment was also a priority. In order not to destroy coastal biodiversity or alter shallow volcanic beds, from The Confidential detail that it was used the “directed drilling” technique: an underground microtunnel that allows the cable to exit to the sea hundreds of meters from the beach. Likewise, the terrestrial substations use GIS (gas-insulated) technology to occupy the minimum possible space, and their buildings have been camouflaged imitating greenhouses and agricultural terraces to integrate into the landscape. Laying underwater bridges. The milestone of La Gomera and Tenerife is just the beginning. Future planning, as pointed out The Daycontemplates the colossal challenge of joining Fuerteventura with Gran Canaria, an even greater challenge given that the distance between the two exceeds 100 kilometers. Parallel to the electrical revolution, the Canary Islands are experiencing an unprecedented leap in their telecommunications. As these local media detailthere are more projects like BASE 6, promoted by the public company Canalink. This is a new 328 kilometer fiber optic cable with a budget of 19 million euros that will link Tenerife with El Hierro, landing through a drilling on Tamaduste beach. This data highway, with a capacity of 5 terabits per second, seeks to eradicate the digital divide on the most remote island, guaranteeing services such as telemedicine or online education. The invisible network. The Canary Islands not only look inward. As contextualized by OCTSI (Canary Telecommunications Observatory), the archipelago has been functioning for decades as a global strategic node, surrounded by historic fiber rings and international connections such as Telefónica’s PENCAN cables, currently in the process of renovation. However, this strategic position has its geopolitical edges. An extensive report from my colleague for Xataka focuses on network extension from Canalink to Africa. The Canary Islands are financing a cable to the Moroccan city of Tarfaya with European funds. The problem lies in the fact that Morocco intends to extend this infrastructure towards Western Sahara, a movement that clashes head-on with the rulings of the EU Court of Justice and that threatens to place Spain at the center of a complex diplomatic and legal conflict with the Polisario Front. Overcoming geographic isolation. At 1,145 meters under the scrutiny of the waves, where sunlight does not reach and the pressure is unbearable, the heartbeat that unites two islands now runs. The Canary Islands are managing to transform their greatest geographical weakness—fragmentation and isolation—into a true global showcase of technological innovation. Little by little, the old and noisy combustion engines give way to a future that will be inescapably green, and deeply interconnected.

It is the secret document of salvation

by

Yeah your house starts to burnWhat is the first thing you would save? Surely you have asked yourself that question more than once, with a very clear answer in your head that, once you save what you love most, it is completed with “if I can take more than one trip, I would take this and that.” Being prepared is not badbut… what if instead of personal objects, you had a museum with hundreds of unique objects and works of enormous value? They have thought about that. And the plan is perfectly imperfect. Grab lists. Whether of greater or lesser importance, everyone has unique pieces in the form of artistic creations or elements that have helped us understand and admire the past. And, when there is an emergency, you cannot improvise. That is why each museum has a salvage list or priority list that basically lists the most important objects for the institution and puts them on a list with all the details to keep the piece safe. Because we don’t talk about robbery cases like that of the Louvrebut fireswater leaks, gas leaks, floods and even terrorism. In short, it is a printed and secret plan that museums wish to never have to use for logistical reasons, but also for ethical reasons and responsibility with the art they treasure. How to do it. In this document We see it as a guide to react and make the list. They range from small museums, where perhaps more material can be saved, to large museums where the pieces must be organized in detail. If something happens, the rescue list is given to the emergency services (firefighters during a fire, for example), and should be compiled based on: The rarity of the item. Its value (although they indicate that it should not be the only element to consider, we will see what happens when there is a lot of money at stake). An important historical link to the museum or city. Its vulnerability to fire or floods. An example. The guide is a sample of that safety document that tells staff how to react to different conditions. For example, if there is an electrical failure, recommendations are given such as assessing whether there is a risk of electrocution and, if everything is safe, starting to proceed. If there is an insect infestation, it is indicated how to save the works. But what interests us are the examples of the priority list. On a map of the museum, they indicate which works need to be saved, accompanied by the number they have on that priority list. But, in addition, a series of instructions must be given so that personnel outside the museum (the aforementioned firefighters, for example) are clear about how to act. In this table, the guide includes the reference number of the object, a photo of it so that you are clear about what it is, if keys are needed to access the display case and where they are, as well as handling recommendations (gloves, box, etc.) and how many people are needed to move it. Do not overwhelm with details: the more concise, the better. Powerful knight… That they are secret documents is more than necessary for a very obvious reason: no one who is not strictly involved with the construction security service can know which objects are on the list because there could be leaks. Because, as you may be thinking, the most monetary valuable items would be the first to go out the door in armored trucks. Because maybe he bone of a T-Rex It may be very important on a scientific level, but it will not be worth the same as a painting by a renowned painter. Each object has its insurance premium, and when there is a crisis, the priority is usually clear: save what is expensive. And there is a perfect example: ‘Mural’, by Jackson Pollock. It’s not hypothetical. In a fantastic report by The Economist The case of the aforementioned work by Pollock is presented. Answering how much art is worth is, to say the least, complex, but specifically, ‘Mural’ is valued at 140 million dollars. Painted in 1948, due to different factors it ended up in the University of Iowa Museum of Art. It is, like many other important museums, one that is attached to a river, and in 1993 the first “notice” came. A flood caused water to leak onto the university campus. He sneaked into the basement and warehouse, but the exhibitions continued to be set up and running. In 2008, things changed. A heavy snowfall meant that the ground could not absorb as much water, so the Iowa River overflowed and levels rose. The reservoir to which the city entrusts its protection could not handle that amount of water and had to be evacuated. Decide between two children. At a meeting, those responsible for the safety of the works did not know what to save, so the most interested came in: the museum’s insurer. It is at that moment in which the cultural value and the importance of the roots of the work are put aside to reflect reality: money and the value of the work prioritizes which ones will be saved first. With water at the doors, a few days before the museum was flooded, ‘Mural‘He left on his way to Chicago in an armored truck. Another work, ‘Karneval‘, a 1943 triptych by Max Beckmann, was also transported to the same facility in Chicago, but on a separate truck. Reason? The director of the university told journalists that these works were being moved and the museum management saw it as a reckless act. “Our collection is insured for a third of a billion dollars and now we have people telling the world it’s on its way to Chicago,” said Pamela White, the museum’s acting director. Beyond money. Museum staff moved more than 10,000 works in total, protecting those they had not been able to evacuate and placing them … Read more

Intel has been manufacturing chips for decades only for her. His only salvation is to make chips for all others

by

Let’s make a trip to the past. The year is 1997 and Steve Jobs has just returned to Applebut the state of the company is terrible and its future, uncertain. To try to save her Apple began to look for strategic alliances, and that was when she announced an absolutely unusual with Microsoft. Bill Gates’s company would invest 150 million dollars in Apple And both would collaborate on several fronts. That unique agreement seemed impossible. Both companies were large rivals, but the truth is that both won with that alliance. Now it seems that we could live an analogous situation with two other companies that are also large rivals. On the one hand Intel, which is as low as Apple was in 1997. On the other TSMC, which dominates in the semiconductor market like Microsoft did it in the software then. According to The Wall Street Journalboth companies are negotiating a possible alliance that is certainly surprising, but has very interesting ramifications. If TSMC helps Intel’s “salvation”, That will give you an advantageous position in future agreements with the US government. This government is now the owner of 10% of Intel’s shares, and for better or worse to get along with Intel, it means getting along with the administration. Taking into account the current policy that practically forces to manufacture chips and components in the US to get rid of tariffs, that potential alliance becomes profitable. Not just that. The agreement also favors TSMC interests when avoiding possible antitrust. How is it going to be a monopoly when you are helping a competitor not go to pique? As They demonstrated Apple and Microsoft, eliminating competition is not the only way to win the game. A promising transition The Historical crisis For which Intel has been going through his new CEO, Lip-Bu Tan, to make very difficult decisions. The mass layoffs They are part of that strategy, but the company has also attended a deep restructuring that It is “chopping”. But there is even more. In fact, Intel’s strategy seems to be recognized and Accept the failure of the era of “exclusive chip”. The firm has admitted that manufacturing by and for it had no route, and now wants to focus on a business model on which it is A chips factory for third parties. That is exactly what has placed TSMC where it is. If the alliance with TSMC is completed, a unique strategy would be confirmed by Intel in which in a few weeks we have lived a unique opening to alliances of all kinds and condition: SoftBank injected 2,000 million dollars USA bought 10% of Intel for 8,900 million dollars Nvidia invested 5,000 million dollars Apple is a candidate for a collaboration agreement And now TSMC could also follow those steps All these steps certainly open an escape for an Intel that seemed to be against the strings. If such alliances fruit, Intel will only lack his two great future objectives. The first, fulfill your promises With the 14th node to which everything has opted. The second, Get customers For that node. And that is where those agreements can be very useful. Image | Intel In Xataka | Intel has confirmed that the 20A node will be skipped to reduce expenses. The 18A node will enter production in 2025

A century of herbivores at ease was ending with Yellowstone. Salvation was logical: call the wolf

by

‘Jurassic Park‘He has memorable moments, but perhaps a phrase is the one that fell me the most in his day: “Life makes its way”The problem is that the hand of man exercises Too much influence on natureand the Yellowstone park It is an excellent example of how an ecosystem that was regulated perfectly was twisting due to a decision made 100 years ago: eradicate the wolves. Consequence? May the park run out of trees. And to turn to the tortilla, the researchers had an idea: return to repopble Yellowstone with wolves. Yellowstone in short. The arrival of European settlers to the North American west caused the expansion of the agriculture and, above all, livestock (With grazing and the Basques carrying the reins). The enemy of cattle was the wolf, since it was a direct threat and, due to its vital role for the local economy, extermination campaigns began to be carried out. The result was that, by 1930, the wolves (as well as other predators such as pumas, coyotes and bears) practically disappeared from some areas such as Yellowstone. Even the army is implied. If the predators disappear, those that were their prey have free field to reproduce without control, and that caused that alces and deer proliferate, creating a huge imbalance in the population of herbivores and, therefore, in the flora of the park. In the end, overparation and a overpopulation of wild herbivores caused the trees to disappear from Yellowstone. Lobos, to curra. The trees that worried were the scenes and it is not a matter of the alces to stay without food. How can we read in Oregon State UniversityThey are vital elements for birds that nest in them and for beavers, among other species. Thus, in 1995 the decision of V was madeOlver to incorporate those predators to the ecosystem. Lobos, Bears and Pumas, another predator practically removed from the area, returned to the place they should never abandon, and the results have not taken to appear. Results. Luke Painter, professor of ecology and conservation at the Faculty of Agricultural Sciences of the University of Oregon, comments that “The reintroduction of great carnivores has started a recovery process that had been paralyzed for decades. ” studyThey detail that the “price” is the sustained decrease in population of the Cervus canadensisallowing the quarrels to experience exceptional growth. This “trophic waterfall” examined 87 rhods of poplars in northern Yellowstone, finding that 43% of them presented a new population of small trees between five and ten centimeters in diameter, being the first positive count since the 1940s. They comment that the density of grazing remains the dominant factor for the regeneration of poplar, but that that Introduction of predators has relieved the load that herbivores exert in the ecosystem. In addition, the study rules out changes in the climate as the main cause of that recovery, once again influencing the importance of the reintroduction of the wolf as the element that has caused “changes in the distribution of the ALCE, giving rise to recovery”. The Wolf as a lever. Not everyone is on that ship. A previous study On the part of researchers at Utah State University and the University of Wisconsin Stevens Point put on the table that, although the role of the wolf had been important for the recovery of poplar, its role was exaggerated due to the way in which previous measurements were made. But what has happened in Yellowstone is not an isolated story. That persecution of the wolf has been lived in other areas and, in Europe, due to its impact on livestock, they are also promulgated laws for extermination. The ecological consequences are similar to the views in Yellowstone and, in Scotland, there is an overpopulation of red deer that are ending local forests. At a time when we need trees so that They catch co₂it is already being raised release more than 150 wolves in the ‘Highlands’ Scottish to control deer and save forests. While some release them… But as we are condemned to repeat the story, at the end of 2024, the Permanent Committee of the Bern agreement voted in favor of reduce wolf protection status. This makes it “strictly protected” to “protected”, which opens the door to A desire on the part of certain parliamentariansfarmers and hunters: that can bother the wolf. And not with paint ballsas in Netherlands. In Xataka | Russia has found a frozen wolf 44,000 years ago “in perfect condition.” First decision: open it

Spain looked at Chinese cars as a salvation table. In the commercial war, the risk of dying drowning runs

by

“Spain is in favor of more balanced relations between the EU and China,” with these words Pedro Sánchez, president of the Government, has defended his approach to China before the commercial war that is being freed and during the same. And the automobile sector has a lot to do. “Essential partner”. With those words Pedro Sánchez has defined the relationship that China should have with the European Union. The words have pronounced them during their meeting with Xi Jinping, president of the country. The Spanish is in a round of visits by Asia in which he is stopping in China and Vietnam. Both countries have been severely punished by the United States. China still maintains 125% tariff Despite the 90 -day truce that Donald Trump has granted. Vietnam had been punished with some 46% tariffs. The importance of words. This “essential partner” is not accidental and shows Spain’s approach to China in full tension for the commercial war that are pounding the United States and the Asian country. In fact, the words of the words of the European Union is unmarked as “partner, competitor and systemic rival”, collected by The country. Sanchez needs to play with tact with his statements. Only a few days ago, Scott Besent, secretary of the United States Treasury, said that “I am not sure if it was the prime minister or the Minister of Economy of Spain, who made some comments this morning: ‘Maybe we should align more with China.’ That would be to cut off the neck”, in words collected by The confidential. Xi Jinping, meanwhile, thanked Sánchez for the “firm will” to maintain good relations between the two countries, emphasizing that it is the third time that the president of the Spanish Government visits the Asian country, they point out in The world. The equilibrium game. Spain has encountered the most uncomfortable view at the right time. With the agenda already scheduled, it was seen if the president of the Government would be willing to go to China in the middle of the commercial tension with the United States. The single presence is seen as a Spanish approach to the Chinese side and, of course, It is unmarked from European politics that bets to get wet as little as possible. However, Spain has a good number of Chinese investments in our country. The commercial balance between the two countries It is still very unbalanced In favor of China (we import goods worth 45,174 million euros and export there products worth 7,467 million euros) but China has the key in key sectors. Putting the carpet. Without a doubt, one of the sectors in which Spain wants to influence is the car. China is disembarking in Europe. His commercial war with the United States will force him to disembark in greater force in Europe and Spain is a perfect gateway. With the fees to the electric car, the plug -in hybrids and the Chinese low ranges vehicles have A huge opportunity in countries like Spanish where “electricity” is not so developed. All their companies need to open markets outside China to seek profitability. If the perspectives are maintained, byd will be in 2025 One of the five greatest manufacturers of the world. Given this situation, Spain is clear that it wants to be a very important part of Chinese landing in Europe. The automobile sector is essential for Spain. Not only in its factories, you have to add ports that receive cars, distributors and a Powerful auxiliary and component industry. It is better for us. The biggest problem facing Spain is that it is best to open to China if you want to open your business routes in the automobile sector. When the tariffs of Chinese electric car were voted for the first time, Spain was favorable. A visit to China and a threat of attacking the Spanish pig directly (whose exports to China are key) He changed the Executive idea. But, in addition, other threats float in the air. In Europe, France or Italy remained firm in their favorable vote to tariffs on Chinese electric cars. Then, China ordered to stop investments In those countries and since then we have not had news of new approaches. At the moment, Spain has Chinese investments in different ports To receive and start distributing cars that arrive from Asia, the investment of Chery in Barcelonathe agreement between Catl and Stellantis For a battery plant in Aragon or the Extremadura projects to produce batteries for electric cars. But there are certain problems. In a first reading, it seems clear that if Spain has the opportunity to continue expanding its Chinese investments in the automobile sector to be key in the European car of the future and if you have a threat to its head of withdrawing investments or torpedoing trade between the two countries, the approach to China seems completely logical. The problem is to pull the rope tense, irremediably, on the other. The United States has already warned Spain that its position is not correct and some sectors are (obviously) worried. The direct impact In the automobile industry it is not too high but, for example, shipments to the United States of olive oil They have shot under the threat of tariffs. What can we expect? Given this context, Spain will have to play its cards to several bands. Approach enough to Beijing but without burning. It will be necessary to see if the United States maintains its commitment to tax trade with the European Union with a flat rate or if it extends tariffs by sectors, which can be an indirect attack on a specific country. A good example is the 25% tariff to the car. The United States government has repeatedly decided to pause its tariffs to Mexico or Canada but keeping them in the car market is a clear attack on these countries. Also to Germany, in Europe, which is The country that exports more vehicles to the United States. We will have … Read more

For years the prefabricated houses were the ugly duckling of the house. Now the Basque Country believes that they are its salvation

by

The Basque Country wants more housing. And it has A plan to get it: Bet on prefabricated constructionsa model that over the last years has gained weight in the real estate sector but that – that –They recognize From Euskadi – it loads with the negative image that still has the “prefabricated” among part of the population. To clear doubts, knock down prejudices and above all make clear its institutional commitment, last week the Basque Government presented its’White Book of industrialized social housing ‘. “It is essential to knock down biases,” claims. Housing deficit. The Basque Country needs more housing. Or so those responsible, which recently estimated that the current construction rhythm is insufficient and the region loads with a deficit of some 1,500 annual houses. The problem is not only that gap between the creation of new homes and demand, but to what extent it influences a market that, according to idealist data, has seen how in a matter of only one year the prices of sale rose almost 7% and those of rent 8% In Euskadi. … and “structural deficits”. A few days ago, speaking precisely about the real estate market, the Minister of Housing and Urban Agenda of the Basque Government, Denis Itxaso, warned of another very related “deficit”: the one that drags the industry itself. “The construction sector has structural deficits, such as lack of labor, challenges related to training and professionalization and a higher speed in construction processes,” he reflected. The relationship between the two problems is evident: the lags in the industry affect their ability to increase the offer and satisfy a residential market. “The challenge that represents the scarcity and housing failure requires balance the market with the greatest offer,” The regional head advocates of urban agenda. In his opinion, Euskadi must endow “his own strategy.” And precisely for that reason a few days ago the Executive presented A document: his ‘White Paper of Industrialized Social Housing’. What strategy is that? The book and the act during which it was presented – in which Itxaso and the director of the Public Society for Protected Housing Promotion participated Visesaamong other positions related to the sector – served to give a track of where the Basque Country wants to go. His government looks with special interest the “industrialized” buildingsreal estate that are created with previously manufactured pieces in a ship instead of following the traditional method of lifting walls and forged in situ. “The way to reduce deadlines”. During The presentation From the manual, held in Bilbao, there was talk of sustainability, digitalization, security, improvement of working conditions, inclusion and also a formula that allows the sector to “respond to the housing and labor deficit”. “The ‘White Book’ includes examples of good architectural practices, highlighting how the use of industrial processes should be the way to reduce execution deadlines and minimize environmental impact,” the Basque Executive ends in Your statement About the act. Along the same lines, the Visesa director pointed out that industrialization is “fundamental” to build “quality housing”. Issue of challenges. Not everything is facilities and clear path in the future of prefabricated housing. During the event there was also talk of “the administrative, financial and regulations barriers that still persist” and the important role that the public administration plays, especially “assuming the role” of promoter. However, if there was a challenge for industrialization in which the accent was accent in Bilbao was another, one other than bureaucratic obstacles or difficulties in getting credit: the image. Perhaps more modular houses are seen today than a couple of decades ago, but the big question, especially if we want to strengthen its weight in the sector, is … What concept do we have of them? “One of the main challenges is citizen perception towards what is considered ‘prefabricated’, often associated with lower quality or provisionality,” admits the Basque Government in Your statementin which curiously only that word is used once: “prefabricated.” Itxaso himself assumes that he “demolish preconceived biases and ideas.” Of the theory … To practice, there is. Visesa He spoke too of the development of about thirty protected homes in Sopela-Asu, in the province of Vizcaya, using precisely “industrialized construction processes.” In the sector, prefabricated, industrialized, modular solutions are also expanding time … and although in Spain they still suppose A modest part of the sector, in other nations, such as the Netherlands, Germany or the United Kingdom, they have managed to get a respectable presence. Some construction companies trust that in a few years industrialization is a significant part of their income. In their favor they do not only have the impulse of the Basque Government, which for another part has already seen On other occasions His commitment to industrialized homes. At the state level the PP has been in favor also to promote this kind of buildings to stop The housing problem In Spain, following the example of countries Like Australia.
