50 years ago, an inventor introduced the first water engine. He was Spanish, a visionary and a complete fraud

by

“Of my patent, the license for Spain is transferred free of charge to the State for the benefit of all Spaniards.” Loud and clear, this is what Arturo Estévez Varela, the inventor of the water engine and, without a doubt, a great Spaniard. At least that’s what they must have thought. NODE viewerswhich in the early years of the 1970s included the words of this man from Extremadura. “That died with my father and we haven’t bothered to move it either,” said Arturo Estévez Jr. in a report for RTVE in 2009. Perhaps due to lack of knowledge or, probably, due to having too much knowledge. Knowledge that the invention, in reality, was completely unrealizable and that the patents shown to the journalist from the public entity have no value. But who was that man in a suit who drank from a jug before filling the tank of a motorcycle with water and made it work? Behind the name of Arturo Estévez Varela there was an inventor, an enormous visionary and, why not say it, also a scammer. Before his water engine, this Extremadura native born in Valle de la Serena (a small town of just over 1,000 inhabitants in the province of Badajoz) had already devised a chicken roaster with infrared and the “wing plane”, a device that allowed rockets to be recovered. Space X in Franco’s Spain. Arturo Estévez Varela in a demonstration of his invention With four liters of water, 900 kilometers of autonomy But if Arturo, who perhaps at this point we should start calling Don Arturo, became famous for something, it was for his water engine. An invention that, according to what he said, allowed you to travel by car 900 kilometers with just four liters of water. Statements included in the press of the time. It was October 1970 and, evidently, it seemed like magic. How did good old Don Arturo get a motorcycle he was taking around Spain running? Yes, with water, but also with hydrogen. Water was only one of the pillars of his invention. The third was hydrogen. And the second, a mystery. Town to town and city to city, Don Arturo traveled throughout Spain, generating a stir as he went, capturing the attention of the press and, as we have seen, also of the NODO. What this Extremaduran inventor did not reveal was what was hidden in that substance that, together with water, allowed the combustion engine of his motorcycle to work. In theory, the water reacted with a mineral that Arturo did not want to reveal. This reaction produced hydrogen which, when burned in the combustion engine, made the motorcycle work. That is, the procedure was similar to that have tried in Toyota. It is not a motor fuel cellis a combustion engine that burns hydrogen, a much more inefficient process. If we consult different sources on the Internet, many agree that the Francoism came to order a technical report to check if what that unknown inventor said was true. Obviously, everything was left in water, yes, but borage. missing These same sources end their story at the same point. Don Arturo was tireless in making himself heard, in convincing people and strangers that his invention worked and that it was the solution to many of Spain’s problems. However, it disappears. Nothing else was heard of him and the fables begin. Since the Franco regime tried to hide the invention until the oil companies decided to silence it. It seems that the secret, however, was not so secret. In this blog They recover a large part of press clippings from the time. Shortly after making himself known and without being listened to by the Government, Don Arturo managed to get someone to trust him. That someone was José Carrera Rey, a businessman who bought half of the rights to the invention at a price of six million pesetas. It is at that moment that Don Arturo loses track of him. José Carrera Rey then discovers that he has in his hands an invention that is useless. What it doesn’t have are six million pesetas and he doesn’t have a partner either. In desperation he denounces Don Arturo but nothing is heard from Don Arturo again. Only an indictment, in 1974, for an alleged crime of fraud, managed to get Don Arturo to appear in court. However, in December 1977 the magistrates were clear: Justice matters were already going very slowly in Spain and Don Arturo had not committed any crime of fraud because he believed in his invention, so there was no type of deception. Due to the dates on which the Spanish Television report was recorded and what his son says, Don Arturo died on the border of the 80s and 90s and took his secret to the grave. A secret which, according to the scientists who have studied the case, was boron. He boron It is a chemical element that, in reaction with water, produces hydrogen that, even, can become inflamed due to the enormous heat released. Hence, Don Arturo always warned that his “secret mineral” and water had to be mixed in controlled quantities. As collected The Vanguard last summer, the water engine, therefore, is perfectly functionalbut very little useful. To obtain 5 kg of hydrogen, with which a fuel cell Toyota Mirai (more efficient than burning hydrogen) travels about 600 kilometers, 45 liters of water and 19 kg of boron are needed. The problem is, basically, the 68,000 euros that 19 kg of boron would cost, according to what was reported in the Catalan newspaper. Was it functional? Of course, but, at its side, the first liter of synthetic and emissions-neutral fuel at 2,800 euros It no longer seems so expensive to us.

the Spanish space startup grows with Japanese money

by

PLD Space has closed a Series C round of €180 million led by Mitsubishi Electric. With this injection, the Elche company exceeds the 350 million raised in total and has a clear path to carry out the first demonstration flight of its rocket Miura 5 before the end of 2026. Why is it important. Spain has very few technology companies capable of raising this type of money on a global scale. PLD Space has not only achieved this, but has done so by attracting a top-level Japanese manufacturer that is not coming to make a financial bet but to secure access to launches for its clients in Asia. That difference between a financial investor and a strategic investor changes everything. Between the lines. Mitsubishi Electric has also signed an MOU with Lockheed Martin to collaborate on geostationary defense satellites. That the same week in which he signs that agreement he also leads this round in PLD Space is no coincidence. Japan is building a chain of access to space so as not to depend on anyone, and PLD Space fits as a provider of low orbit launches for the constellation of satellites that that ecosystem needs. For the Spanish company, this means support that goes beyond capital: it is a seal of industrial credibility. In figures: 180 million euros raised in Series C. More than 350 million in total accumulated financing. Planned capacity of 30 launches per year by the end of the decade. The Miura 5 can place up to 1,080 kg in low orbit. Target production: 4 rockets in 2026, 6 in 2027. The context. Europe has had the problem of access to space on the table for years. The delays of Ariane 6 and the dependence on American launchers have made it clear that the continent does not have a mature private alternative. He European Launcher Challengewhich calls for a test flight of a higher-capacity rocket before 2028, has acted as an accelerator for PLD’s roadmap. The company already designs the Miura Nextdesigned precisely to meet that institutional challenge. The big question. PLD Space has proven that it can raise money and that it can fly hardware. He Miura 1suborbital rocket, completed its first launch in October 2023. But the jump to orbital is different. Many launch startups have raised hundreds of millions and have not reached orbit. The real test begins when the Miura 5 takes off from Kourou, whose facilities should be ready in July. Until then, money buys time, but not guarantees.

the great paradox of Spanish energy

by

The Spanish energy market has broken into two halves that seem to have no relationship with each other. On the one hand, the trench of the retail market—direct sales to consumers—has become a scenario of continuous attrition where historical giants are bleeding customers at an unprecedented rate. On the other hand, the boardrooms of these same corporations celebrate the highest profits in their entire history. How is it possible to make more money than ever by losing hundreds of thousands of customers? The answer defines the new paradigm of the sector: large electricity companies are ceasing to be “light sellers” to consolidate themselves as managers of colossal infrastructures. The real business is no longer in fighting the average citizen’s monthly bill, but in controlling the cables, regulated assets and energy demanded by the new technological giants. The bleeding of the 1.3 million contracts. The closing figures for 2025 draw a historic leak. As detailed The IndependentIberdrola and Endesa suffered an “unprecedented fall”, jointly losing almost 1.3 million customers (1,279 million exactly) in the electricity and gas markets. Endesa left 645,000 contracts behind, while Iberdrola lost 634,000. The attitude of companies towards this flight of users is radically different. The president of Iberdrola, Ignacio Sánchez Galán, downplayed to the matter during the presentation of results, calling it “normal rotation” and boasting of the “enormous loyalty” of its hard core of users. On the other side of the coin, Endesa yes it has set off the alarms: has announced an injection of 900 million euros until 2028 with the urgent objective of recovering half a million customers, even relying on strategic alliances such as the recent purchase of Masorange’s energy business. The feast of alternative firms. In the last year, an absolute mobility record was broken, more than 7.25 million changes of marketer. In other words, almost one in four Spaniards decided to change their rate. The big winners of this stampede have been companies like Octopus Energy, the MásMóvil group and, most especially, Repsol. The oil company has already established itself as the fourth electricity operator in the country, exceeding 2.1 million customers and taking market share directly from traditional electricity companies. The model breaks, but the box is full. Any traditional economics textbook would say that losing more than a million customers is a financial catastrophe. However, the balance sheets say the opposite. How to publish Five DaysIberdrola pulverized its brands by earning 6,285 million euros in 2025 (12% more than the previous year), while Endesa reached 2,351 million (18% more). The secret of this paradox explains it perfectly The Mail When analyzing Iberdrola’s accounts: the net benefits that come from the management of distribution networks skyrocketed by a brutal 77%, while the contribution of the energy generation business fell by 27%. In simple words, they earn less by selling electricity to the end customer, but they earn much more by charging the regulated “toll” for using their cables, especially in markets with very attractive legislation such as the United States and the United Kingdom, which already account for 60% of their investments. The future runs through the cables. Electricity companies are going to stop obsessing about installing solar panels at any price to focus on the sockets and transmission highways. Endesa will invest a record figure of 10.6 billion until 2028, allocating more than half (52%) exclusively to electricity networks. Simultaneously, it will put the brakes on renewable energy, cutting its investment by 20% due to the “cannibalization” (plunging prices) that solar energy suffers during peak production hours. Iberdrola follows the same path: 62% of its gigantic investments last year went to the networks. The other great vector: data centers. Endesa already has some 3,000 MW of capacity ready to feed these insatiable technological infrastructures, highlighting its hybrid macroproject in Pego (Portugal). All of this will require a much more robust national backbone; Therefore, Redeia (parent company of Red Eléctrica) will skyrocket your investments 70%, injecting 6,000 million into the high-voltage transmission network to support this technological boom and the electrification of the country. Furthermore, this scenario comes with strong pressure of both companies for extending the useful life of Spanish nuclear plants, such as Almaraz, defending that they can operate safely up to 80 years to guarantee cheap and stable base energy that the system urgently needs. Network saturation and market clearing. The regulatory context explains many of these operational decisions. Spain faces a monumental bureaucratic funnel: 83.4% of electricity distribution nodes They are administratively saturatedwhich keeps 130 GW of renewable energy locked in, even though the grid is physically underutilized. To avoid the collapse of reindustrialization, the CNMC is designing new “flexible access permits” that will change the rules of the game. At the same time, the bottom of the market pyramid is undergoing a silent purge. The Government started a few months ago a historic cleanup of the “ghost marketers.” Of the more than 900 firms registered in Spain, only 416 had real activity. The Ministry for the Ecological Transition has already begun to disable inactive or delinquent companies, transferring their clients to avoid systemic risks and clean up a hypertrophied market. The definitive metamorphosis. The traditional electricity bill is no longer the main battlefield for the great energy totems. While they gladly cede – or out of pure wear and tear – the exhausting hand-to-hand combat of the retail market to independent marketers and oil companies in the midst of a green conversion, Iberdrola and Endesa have ascended to a much safer, more profitable and macroscopic ecosystem. They have understood that the future does not belong to whoever sells electricity to the final consumer, but to whoever owns the highways on which, inevitably, all that energy will have to circulate.

the great Spanish paradox of forest risk

by

It seems like a contradiction, but that’s how paradoxes work. And this one in particular is so problematic for Spain that in nine out of ten configurations the result is always the same: whatever happens is bad for fires. But why? I mean, how is it possible that whether it rains or not, this country always has a problem with flames? The world on two scales. If it doesn’t rain, if we endure weeks or months of drought, the humidity of the material accumulated in the mountains (grass, bushes, leaf litter) drops. In addition, the soil temperature rises and living vegetation begins to become stressed. Just one spark is missing and boom, we have a fire source that is very difficult to stop. That is, drought worsens the risk today. The rain makes it worse, but it will do so tomorrow. Because if it rains, the vegetation grows (especially what we call fine fuel) and the continuity of the scrub increases. It’s biomass, biomass and more biomass. If it rains there is no risk, if it doesn’t rain: it is material that sooner rather than later will become fodder for the flames. The hell of the summer of 2025, started in spring… Sometimes we don’t focus much on this: wet springs are wonderful, but in our case it is also a potential danger. Not only because of what I explained above, but because (also) no one manages it. And that means that, if the trend continues in the direction it is going, we have to start seeing rainy winters as more than just a way to save the season. We must begin to see them as a clear reminder that we must invest in prevention, plan devices, firewalls, fuel management and all types of extensive farms that help contain the problem. Because climate change is not just “warmer.” A few days ago, AEMET itself reflected on How rainfall records are changing. Changes in the landscape and rural abandonment are a permanent source of problems and the so-called “bullwhip effect” only increases them: growth phases and drying phases that never stop coming and going. So yes, the great Spanish paradox with rains and fires is this: no matter what happens, in the coming years, we will always have problems with fires.

Two Spanish space giants have joined forces to take 5G defense satellites into space: PLD Space and Sateliot

by

Two Spanish companies they have sealed an agreement to launch new generation satellites without depending on any other foreign company. In Europe we have been with the run run of technological sovereignty. This agreement is a perfect example of this, and also a milestone for Spain if the project ends up materializing. The agreement. PLD Space, manufacturer of the Miura 5 rocket based in Elche, and Sateliot, a telecommunications satellite operator based in Barcelona, ​​have signed a contract to launch two satellites from Sateliot’s Tritó constellation aboard the Miura 5. The launch is scheduled for the last quarter of 2027, expectedly on the fourth commercial flight of the Elche rocket, and will do so from the Kourou Space Port, in French Guiana. Each satellite weighs about 160 kilos and will be launched on a dedicated mission, without sharing space with other operators. Why is it important? This agreement is presented as the first entirely Spanish private space mission, with satellites designed, manufactured and operated in the country, launched using a rocket also of Spanish origin. And the interesting thing about the project is that it would cover the entire value chain of the sector (manufacturing, launch, operations and commercial exploitation) without foreign intermediaries. Although the European Union has been trying for years reduce your dependence on operators like SpaceXthis alliance fits directly into this context. What are Tritó satellites? The Tritó constellation is a significant evolution of the current satellites that Sateliot has, weighing 15 kg and dedicated exclusively to the Internet of Things (IoT). In this case, the new Tritó have greater capacity and will combine IoT connectivity with direct device-satellite communication (D2D), including data, voice and video through 5G. Marco Guadalupi, CTO of Sateliot, counted to El Español that one of its key points is that they will be able to “establish the connection when the device is in the pocket”, being key for emergencies, natural disasters and defense applications. The risk they assume. Guadalupi does not hide that it is “a risky mission.” The Miura 5 is a new rocket, whose first launch test is scheduled for the end of this year, and its reliability has yet to be demonstrated in real flight. “We are crazy and we know what we want,” I was joking Guadalupi himself in the interview with the media. The Sateliot team claims to have visited the PLD Space integration and testing facilities on three occasions before signing. In exchange for the risk, they get something that few options on the market offer: a dedicated mission, without competing for space, and the flexibility to adapt flight conditions to their specific needs. Review. Last November, PLD Space closed financing of 169 million euros through ESA’s European Launcher Challenge, backed almost entirely by Spain, for launch contracts and improvements to the Miura 5. Sateliot, for its part, has plans to deploy up to 100 satellites in 2028 and aims to reach revenues of 1 billion euros in 2030, according to they count from Reuters. Among its shareholders is Indra, with 4% of the capital. The agreement with PLD Space also occurs while Sateliot is opening market in India. Jaume Sanpera, CEO of the company, traveled to the Asian country coinciding with the announcement, where the company already has headquarters and sees potential for a future business in which they offer connectivity in remote areas. What’s coming Before the satellites board the Miura 5, Sateliot plans to launch a prototype of the Tritó platform in mid-2027 to validate the payload. The more capable commercial satellites would be integrated into the rocket in the final stretch of that same year. Regarding the total number of satellites they hope to put into orbit, Guadalupi counted that “there will be hundreds.” Sateliot’s intention is to centralize launches to simplify logistics, and although they do not rule out other suppliers, they aim to continue working with PLD Space.

Spanish companies have hired again in 2026. The problem is that there is no one to hire

by

Spanish companies start 2026 wanting to expand their workforce, but they face a big problem: they cannot find enough qualified candidates for your vacancies. According to the data of the ‘Labor Market Guide 2026‘ prepared by the consulting firm Hays, companies are ready to grow and hire more staff. However, the labor market has changed and professionals are already they don’t want to give up to their current jobs. Companies step up. The Hays study reflects that 81% of Spanish companies plan to increase their workforce during 2026. The economic growth trend drives the expansion objectives of Spanish companies and, to carry it out, new vacancies have been opened. This growth in job offers is especially noticeable in dynamic sectors such as technology, professional services and industry. However, the big obstacle quickly appears: there are not enough professionals with the necessary training to fill those vacancies. 93% of the companies consulted for the Hays study claim to have serious difficulties in find qualified profilesa percentage that reaches a historical record and is paralyzing many hiring plans. Talent shortage vs. little training. The lack of qualified professionals has become an insurmountable wall in the hiring processes for new vacancies. 85% of companies claim to have launched internal training programs to develop capabilities of its employees. Only 18% of participants openly admit that they are not investing enough in closing this skills gap that holds them back so much. From the employees’ side, the perception is different. Only 48% of employees are aware that training is being carried out in their company to improve their training. This disconnection between what companies promise and what workers see aggravates the situation, making it more difficult to attract and train talent. Qualified external talent is not found, but neither are resources allocated to train the talent that is already on staff. Less job rotation. Unlike what happened years ago, in 2026 professionals have prioritized stability and growth within their company, instead of jumping to another offer. This change in mentality represents a change with respect to the years 2022 and 2023 in which the labor market had high mobility and the workers they changed jobs frequently in search of better working conditions. Even so, 62% of workers feel that their salary does not reflect all the effort that they put in day by day, but that dissatisfaction is not enough to push them to movesince they value stability and personal balance more. Christopher Dottie, regional managing director of Hays for Southern and Western Europe, puts it in clear words: “companies continue to look for talent, while talent continues to look for stability.” Better salary and flexible working hours: keys to attracting talent. To break this inertia and attract available talent, 72% of companies plan salary increases in 2026, with increases of 7% in areas such as customer service, administration and finance, and 6% in the technology sector to meet salary expectations what candidates demand. Furthermore, the flexible days They are imposed as a key piece in attracting talent, although many companies still resist implementing them despite the fact that the vast majority of employees consider them essential for their well-being. In fact, this ability to adapt to demands for flexibility and offer teleworking options is what is tipping the balance. between the public and private sectors.

deal with the websites of the Spanish administration

by

Claude’s latest upgrade isn’t advertised as “smarter”: it’s advertised as an acting agent. Sonnet 4.6 Not only does he reason, he also navigates websites, fills out forms and completes procedures with the mouse and keyboard, just like a person would do. It’s a quantum leap in what AI can do for you, not to you. The demonstration chosen by Anthropic It was a great example: a user renewing his car registration on the website of the American equivalent of the DGT. It seems like a simple, functional and well-designed website. We want to see how it would go with the Electronic Headquarters of the Tax Agency. The context. Claude had already taken a big leap this month with the arrival of Opus 4.6 just two weeks ago. Sonnet 4.6 is the intermediate version, the one used by most users, including those on the free plan, and Anthropic has transformed it into more than just an improved chatbot: its OSWorld scores, the benchmark standard for measuring computer use by AI, have grown steadily for sixteen months. The company claims that tasks that previously required its most powerful model (Opus 4.5 and 4.6) are now solved by Sonnet 4.6, at the same price as always. Between the lines. There is a very clear market strategy here. Anthropic just closed a $30 billion round and aired its first ad in the Super Bowl, taking a dig at OpenAI. Now it democratizes agentic capabilities in its free plan. The objective is not only to attract developers: it is to reach the average user and change their daily relationship with AI. When chatbots started to have memory, our way of interacting with them changed. They went from tools to relationships. When they start doing things for us for real, like booking appointments, filling out forms or managing hellish paperwork, the change will be of a different magnitude. Yes, but. The technical and cultural challenge is enormous. AI that navigates computers is vulnerable to attacks of prompt injection– Malicious instructions hidden in web pages that can hijack the agent. Anthropic has improved the resistance of Sonnet 4.6 at this point, but the issue is not resolved. And that is without entering the ecosystem of European government websites, where the user experience already represents a challenge for us humans. The big question. When does a brutal demo stop being a brutal demo and become something that anyone uses to manage their tax return? That distance, between the promise of the agent and the reality of the digital bureaucracy, is where the real game is going to be played, beyond the hype.

Spanish ants are using other species as “sexual livestock” to expand across Europe. And it’s working for them

by

Nature has given us many ways to reproduce. From the simplest mechanism (clonality) to really very elaborate systems of sexual reproduction: where some species generate males and females, others produce a huge number of ‘morphs’ depending on the season, population density or social caste. But in all these cases, even the most complex ones, “the phenotypes produced by a female invariably belong to the same species.” Or so we believed. Because the Spanish ants have done so by jumping that “apparently universal restriction” into the air and are taking advantage of it to domesticate other species at will. They are doing what? As it sounds: after examining more than 120 populations and sequences of almost 400 different individuals, researchers from the University of Montpellier they came to the conclusion that the queens of Messor ibericus they are cloning males Messor structor to create hybrid workers that allow them to progressively expand throughout Europe. Evidently, although these hybrid workers are used as the workforce of the anthill, we are not talking about a system of slavery of other species analogous to the human systems of ancient times. However, it is fun and very interesting. Juvé et al. (2025) Why is this happening? When we talk about cocial insects, colonies function almost as if they were factories: if there are no workers, there is no nest, no food, and no viable reproduction. What happens in this case is that (according to the researchers) the queens of the Messor ibericus They cannot produce viable workers without the genetic contribution of other species. And, without thinking twice, they do it. Why is it important? For many reasons, but above all because it opens up an incredible melon: it brings back to the debate table the real meaning of “being a species.” It also forces us to rethink what we know about sexual reproduction and allows us to understand colonies as ‘superorganisms’ that are much more complex than we believed until now. So… can we really talk about sexual domestication? In this context, ‘sexual domestication’ appears as a visual metaphor of a complex process. However, there is no doubt that the appearance of colonies with internal reproductive ‘livestock’ changes the rules of the game. And not only on a scientific level: the fact that they are gaining ground throughout the continent shows that the strategy is successful. Very successful. Towards a European hegemony of the Spanish ant… No no. We can hardly say that. Today, all the ants on the continent are experiencing a real invasion: that of the Argentine or red fire ants. This is a biological invasion linked to globalization. In this case, what is happening is that by freeing yourself from dependence on M. builder (because it can produce reserves of its genetic material without needing colonies of this species), the M. ibericus They can move with complete freedom and that means they are moving into new and unexplored territories. But the complete battle, facing the fire ant, is yet to come. And they are already losing it.

The extreme stress of the Spanish water network explained from within

by

The images have flooded social networks this weekend: the Aldeadávila dam “turbinating at full capacity” with the Duero river descending with enormous force, or the Iznájar reservoir recovering its splendor in a matter of days. They are hypnotic images that hide a much more tense and calculated reality. While the citizen sees natural spectacles, the engineers see a fight against the disaster. In the midst of this “festival” of storms that has shaken the peninsula this month of February, One phrase sums up the situation better than any other. It is pronounced by José María Sanz de Galdeanodirector of Hydrological Planning and Works of the Basque Water Agency (URA): “The dams were not designed for floods, but today they are key to cushioning them.” These infrastructures, designed decades ago so that water comes out when you turn on the tap or to turn on the light, have become—almost by historical accident—the last line of defense between the perfect storm and the safety of the populations downstream. A winter concentrated in a few days. To understand the magnitude of the event, we must first look at the Basque Country, where the orography and intense rains have tested the system. As explained by Sanz de Galdeano in the SER ChainEuskadi has faced a winter marked by episodes of very intense rain concentrated in very few days. The situation has forced the activation of the two major Basque regulatory systems. On the one hand, the Zadorra system composed of the Ullibarri-Gamboa reservoir and the Urrunaga dam. On the other hand, the Añarbe system is responsible for supplying the Donostialdea area. It is not a local phenomenon. It is a symptom of a broader hydrometeorological pattern that has affected the entire peninsula. While in the Tormes system, reservoirs like Santa Teresa are close to 80% and release water preventively to defend the city of SalamancaIn the south the situation has been even more drastic. In Andalusia, the Iznájar reservoir—the giant of the community— has doubled its reserves in just two weeks, going from a critical 25% to exceeding 50%, something that had not been seen in a decade. The intensity has been such that the AEMET even warned of scenarios of soil saturation with impacts “some of the highest in the world”, causing water to gush directly from the ground in places like Grazalema (Cádiz). forcing preventive evacuations. From supply to “lamination”. The relevant thing about these weeks is not only that it has rained, but how we have managed that rain. Sanz de Galdeano puts his finger on the sore: “These infrastructures were built primarily for water supply, not specifically to laminate avenues.” However, its immense storage capacity has made it possible to change its function on the fly. Dams have acted as giant shock absorbers. “They have sufficient volume to play with reserves, create space and retain water at the most critical moments,” says the director of URA. Sanz de Galdeano’s warning has scientific support. A study on the effectiveness of dams in the face of climate change confirms that infrastructure designed with “historical data” They are operating blind to the new reality. Old models did not account for this extreme variability; under severe warming scenarios, the risk of large dams overflowing could multiply by up to 17 compared to historical records. The conclusion is technical but terrifying: the effectiveness of a dam decreases dramatically under extreme hydrological regimes if adaptive management is not applied. This excess water has had an unexpected side effect on the energy market: Spain’s “battery” it’s so loaded (117% more stored hydroelectric energy than last year) that nuclear energy is no longer competitive. The Trillo plant, for example, has been disconnected from the grid because, given such an abundance of turbineable water, the numbers simply “did not add up.” Choreography of floodgates. The precision mathematics that decides how much water reaches your home. The management of these crises is a precision choreography that Sanz de Galdeano graphically defines as working “with one eye on the river and another on the sky.” The technical key lies in the “reservoir”: the empty space that is deliberately left in the reservoir before the rain arrives in order to swallow the flood. The director of URA details how it is applied this differently depending on the capacity of each system: In the Zadorra (High regulation): These dams control 60% of the upstream basin. This allows for drastic intervention. The figures from Sunday night are the best example: 260 cubic meters per second of furious water entered the system, but the floodgates only let out 54. That difference (more than 200 m³/s retained) is the flood that was avoided. In Añarbe (Less regulation): Here the dam only controls 23% of the basin. Most of the river water circulates freely, so there is less room for maneuver. Even so, the strategy is the same: when the river goes high, floodgates are closed to retain “as much as possible.” All this is done under administrative coordination complex but fluid between URA, the Ebro Hydrographic Confederation and that of the Cantabrian Sea. Not all barriers are the same. In this context of saving dams, a reasonable question arises: why then are some dams on Basque rivers being demolished? Sanz de Galdeano makes a crucial distinction between large regulatory infrastructures and small weirs. “These are not large infrastructures like those of Zadorra, but rather low-rise structures that have no real capacity to manage avenues,” he clarifies. The elimination of these small obstacles responds to two logics: Environmental: they allow fish and fauna to ascend the river, improving ecological health. Hydraulics: Although it may seem contradictory, these small walls can raise the water table in local floods, worsening the problem instead of solving it. However, large dams have their own silent enemy: sediment. Experts and organizations like Greenpeace warn that torrential rains They drag tons of mud that accumulate at the bottom of the reservoirs, subtracting their real capacity (that “hole” that Galdeano spoke of) and … Read more

“We are willing to further strengthen cooperation with the Spanish parties”

by

Europe continues to discuss how to deal with China. Spain, meanwhile, has already opened all its doors. Several times. The International Department of the Chinese Communist Party (an organ of the Party, not the State) has made Madrid a mandatory stop for its parallel diplomacy. At the end of January, Vice Minister Ma Hui toured the offices of the PP, the PSOE, the PCE and the Catalan Generalitat. No one closed the door. Why is it important. China is not looking for ideological allies in Spain, what it is looking for is access. Their strategy is to build relationships with whoever governs today but also with whoever can govern tomorrow. The CCP’s International Department maintains contacts with more than 600 parties around the world because it does not understand colors, only influence. And Spain, due to geography, economy and political predisposition, has become its bridgehead in southern Europe. Between the lines. Zapatero once again appears as a key piece of this network. Ma Hui, a veteran diplomat and former ambassador to Cuba, met him first, before anyone else. It is not coincidental. The former president maintains recurring contacts with CCP structures, appears at Party-sponsored forums in Beijing and operates as an unofficial facilitator. A role that raises questions about transparency and red lines in international relations, especially for someone without official position but with privileged access, which we now know is is on the payroll of a Chinese manufacturer to help it deploy in Europe. The contrast. Trump has based part of his legislature applying tariffs and generating uncertainty with them. China, meanwhile, has wanted to position itself as its opposite, as a guarantor of tranquility. It has presented its Five-Year Plan (2026-2030) in Madrid as a model of stability. Yes, but. Spain is moving with respect to China faster than the rest of Europe. Pedro Sánchez plans his fourth trip to Beijing between April 13 and 15. And this pace makes Brussels uncomfortable because it is trying to coordinate a common European position towards China. Spain can clearly benefit economically from this stance, but at some point we will have to ask ourselves what we are giving up in exchange. The money trail. China no longer only pursues markets in Spain, it pursues political legitimacy: Ma Hui participated in a forum Chinese Chaira think tank geographically close to Atocha but strategically very close to Beijing. These spaces, halfway between academia and propaganda, normalize the Chinese presence in European decision-making centers. They say they want to “learn about state management.” In reality, they build a network of interlocutors that facilitate their strategic interests. ¿Main loser? The common European position. If Madrid negotiates on its own, Valencia too, and Barcelona the same, China does not need to convince the European Union. It is enough to fragment. Bilateralize what should be multilateral. And Spain, with former leaders operating as unofficial liaisons, facilitates that strategy.
