Predicting dementia seven years in advance seemed impossible. An AI with Spanish participation has just achieved it

by

The diagnosis of the neurodegenerative diseases You face a problem at the time the diagnosis is made, since in many cases it is diagnosed when the symptoms are already evident and this makes the brain damage irreversible. But… What if we could peer into the future of the brain years before the disease shows its face? This is precisely what a Spanish team has done with a new biomarker. The study. The future of medicine involves making increasingly earlier diagnoses so that the success of treatments is much greater, and now in a recent published article in Science Report The door opens for this to be a reality in dementia. To get here, what the researchers propose, where have you participated Rubén Armañanzas, from the DATAI Institute of the University of Navarra, is the use of a test such as the electroencephalogram together with artificial intelligence to develop a biomarker capable of predicting the risk of dementia with up to seven years in advance. Your methodology. To understand the magnitude of this advance, we must look at the population on which the study was carried out, which are people with subjective cognitive impairment. These are patients who go to the doctor because they notice that their memory is failing, but when they undergo standard cognitive tests, the results are completely normal, so they cannot be given a clear diagnosis even though it seems that something is not right. Until now, medicine found a blind spot in this phase as there was no way to know if these ‘complaints’ in memory were the prelude to Alzheimer’s or simply confusion. But now, the study with 88 older adults with this situation has shown that the brain emits alarm signals long before psychological tests detected them. You just had to know how to ‘read’ them. A new method. Here the research has unified different metrics to be able to read these warning signs. The first thing of all is to use an electroencephalogram to measure brain activity, which is a cheap, quick and non-invasive test. From here, the BrainScope technology platform analyzes this data by looking for 14 specific features related to neuronal connectivity and brain wave behavior. Once these characteristics are ‘found’, an AI algorithm comes in that processes the patterns and determines whether the patient analyzed can progress towards mild cognitive impairment or dementia such as Alzheimer’s. And the results are spectacular, since it has demonstrated outstanding precision when separating patients who develop the disease from those who do not. The future. The great value of this biomarker is not only technological, but also clinical, since the most reliable current tests to predict pathologies such as Alzheimer’s require painful lumbar punctures or scans that are not cheap. A system based on EEG and AI could be easily integrated into primary care clinical protocols or routine neurological consultations as it does not have a very high cost and, above all, is not invasive. The important thing here is to detect neurodegeneration in the earliest phases in order to gain golden time so that new drugs can act at the beginning of the disease and gain years of quality of life.

Skyscrapers are full of glass, so some Spanish researchers have had an idea: let them serve as "solar panels"

by

Every 60 minutes, the Sun bathes the Earth with enough energy to cover the world’s consumption for an entire year. The data, remembered by the Polytechnic University of Madrid (UPM)it’s overwhelming. But there is a problem: harnessing all that energy in our cities hits a literal wall. Classic solar roofs are becoming too small for us in increasingly dense cities, and hanging rigid and heavy panels on the facades of buildings is not a realistic option. To avoid this aesthetic and space blockage, the laboratories have found a pioneering solution: using new two-dimensional materials. These are microscopic layers that will allow the windows of any skyscraper to be converted into totally invisible solar panels. With Spanish seal. The Silicon and New Concepts for Solar Cells (SyNC) research group of the Solar Energy Institute (IES) of the Polytechnic University of Madrid (UPM) has managed to manufacture micro-prototypes of ultra-thin and highly efficient solar cells. The secret of this technology lies in the so-called two-dimensional photovoltaic materials. Imagine a sheet so thin that it is only a few atoms thick; For all practical purposes, it is so thin that physics considers it to lack a third dimension. Science knows this family of compounds with a complex name, transition metaldicalkogenides (TMDC), among which molybdenum disulfide (MoS2) and tungsten diselenide (WSe2) stand out. Their great rarity—and their greatest virtue—is that, despite being an almost invisible layer, they have an extraordinary capacity to absorb sunlight. In Xataka Solar panels have an invisible and very brief moment in which they do not work. And solving it is key to your future The actual scope. To understand this technology, researchers published a study in the scientific journal Nano Energy. In it, they simulated what would happen if the façade of a real skyscraper, the Torre Picasso in Madrid, were covered with semi-transparent windows made with these materials. The results estimate that between 16% and 23% of the building’s daily electricity consumption could be covered. If this technology is also combined with areas of opaque modules, the generation could exceed 30% of the energy needs of the skyscraper. Natural light, real colors and savings on the bill Historically, the big “but” of solar windows has been the poor visual quality. Alternative technologies, such as organic or perovskite cells, often act as a filter that colors the light entering the room in unnatural reddish, yellow or brown tones. As explained by UPM researchersthe structure of TMDC materials solves this root problem: they allow a very balanced absorption of visible light, which eliminates the problem of unwanted “coloring” of light. The result is lighting with a natural and warm tone, achieving a Color Rendering Index (CRI) greater than 90, a very high quality metric for work spaces. In addition to generating electricity, in very sunny places like Spain, these glasses naturally block excessive glare. This means that the skyscraper not only produces its own energy, but also saves a lot of money by not having to turn on the air conditioning as much. From the microscopic laboratory to the factory. Creating these ultra-thin solar cells is a work of very high precision. To manufacture the prototypes in the laboratory, the UPM team has used a technique called hot-pick-up. Using this method, they use a small transparent bubble to select, collect and deposit fragments of the materials, creating tailored stacks that combine the best properties of each one. But the goal is not to stay in the laboratory. IES-UPM researchers are already working with new techniques to scale this process and cover large areas, such as entire windows. According to the scientists themselves“through spraying and deposition techniques of these solutions, manufacturing processes could be scaled, reducing costs and allowing the industrialization of this disruptive technology.” The ace in the hole: catch the lost heat. The potential of these two-dimensional materials goes far beyond solar windows. Another investigation from the same team, published in the scientific journal ACS Applied Energy Materials, demonstrates that by modifying molybdenum disulfide (MoS2) with an element called niobium, the material acquires impressive thermoelectric properties. More simply, this means that in the future, these materials could not only capture sunlight, but could also have applications in thermal sensors or in the recovery of energy from the heat wasted by machines or buildings themselves. {“videoId”:”x81qnhf”,”autoplay”:false,”title”:”Is it possible to generate energy at zero cost?”, “tag”:”Energy”, “duration”:”109″} The new skin of the city. The lightness, flexibility and low manufacturing cost of these solar cells makes them one of the most promising options to achieve the desired “green cities”. Two-dimensional photovoltaic technology shows us that the ecological transition in dense urban environments no longer depends only on finding space on roofs to place large rigid panels. The real paradigm shift consists of transforming the very “skin” of buildings – their windows, their walls, their facades – into active sources of clean energy, ensuring that any surface can be an ally against climate change.

Since 2019, Spanish movie theaters have not had so much attendance in a single weekend. The person responsible: Torrente

by

‘Torrente Presidente’ arrived in theaters on March 13 without a trailer, without press passes and with a poster with a black background as the only promotional material. In 72 hours it raised close to 7 million euros: with one million viewers, it is the best start for a Spanish film in fifteen years. And these are the causes of the phenomenon. The figures. The first numbers of ‘Torrente Presidente’, before the weekend ended, were already overwhelming and predicted extraordinary success. Premiere on 1077 screens. 150,000 tickets sold in advance. 2.4 million euros and 300,000 spectators on Friday alone. At the end of the weekend, it had generated a total of 6.94 million euros, 70% of the national box office. Of course, it is the weekend with the highest attendance at cinemas since 2019, before the pandemic. The figure places the sixth installment of the saga as the fourth best premiere in the history of Spanish cinema, behind ‘The Impossible’ (€8.9M), ‘Torrente 4: Lethal Crisis’ (€8.6M) and ‘Torrente 3: The Protector’ (€7.21M). It is also the highest-grossing Spanish film of the year and the best debut of a Spanish production in the last eleven: no national film had reached that level of box office on its opening day since at least 2015. Unusual marketing. Segura opted for a launch strategy completely atypical: The film arrived in theaters without a trailer, without promotion and without prior press screenings, announcing itself only with a publication on social networks. The director has explained that his intention was that fans of the saga would be the first to enjoy it. Curiously, Segura has for decades been one of the most active Spanish directors in the promotion machine, continually appearing on television wearing t-shirts with the film’s title. Once ‘Torrente Presidente’ was released, it has already been seen on programs like ‘El Hormiguero’ and has begun to give interviews and give access to press passes. You know what you’re going for. Curiously, Torrente’s films do not stand out for their plot twists or spectacular surprises, but there is another secret to keep: the cameos. As could be seen when the film arrived in theaters, ‘Torrente Presidente’ is one of the densest films in the saga (if not the most) in terms of number of cameos and guest stars. That was what Segura did not want revealed, and that is why there are abundant articles on the internet that they gut this aspect of the movie. It is the great secret of the premiere, above its plot or its approach, where it rains in the wet. And now what. If in a film like this the surprise effect is important, word of mouth is even more important. From its second week onwards, Segura will adhere to the usual rules of the promotion (trailer, poster, pass, interviews) seeking to maintain the momentum. The first milestone that ‘Torrente Presidente’ has to overcome is the 22.1 million in revenue from ‘Torrente 2’, the most lucrative of the saga to date. At this rate, this second week could exceed the 14 million euros that the intermediate installments of the saga accumulated, amounts that the films of ‘Father there is only one‘.

The number one enemy of the Spanish mountain is called climate change. And we have data to prove it.

by

In 2024, they burned 47,700 hectares. In 2025, 340,000 were exceeded. And honestly, the reasons are manyalmost too many. Well, Marco Turco, from the University of Murcia, just demonstrated something that we already sensed: at a global level, the days of extreme fire risk They have increased 65% since 1980. That’s 12 more days a year. And, if that were not enough, the Mediterranean region is where lthe signs are clearer. What does all this mean? In general terms, this means that although the causes of the fires remain human (in Spain between 80 and 95% of firesin fact; the intentional ones there are many less), climate change has a lot to do with its spread. Increasingly. Why is it interesting? Because this study is the first to apply formal climate fingerprinting techniques on a global scale to fire risk. That is, that figure of 11.66 more days of extreme risk in 44 years is achieved with the most advanced methodology that we have at our disposal. And if the global data is bad, the Mediterranean data (where the days have doubled in these almost five decades) they are horrifying. But it’s not all bad news. After all, as Turco points outdespite the increase in risk, the burned area has not increased proportionally. And the reason, according to him, is the improvement of the means of extinction. However, “when extreme conditions coincide with ignition, the resulting fires are more virulent and extensive.” Why is it news now? Besides because the article has just been published in Science Advances, because the precedent of 2025 (a rainy spring and a terrible summer) It resonates a lot with what we have in 2026. We don’t even have to remember that we are talking about a handful of months with truly incredible accumulated rainfall and that is generating an amount of material in the field that can easily be end up turning Spain black. Because the core of Turco’s work is that the conditions that allow fire to spread and become a big fire They are stronger than ever. Furthermore, human exposure to these types of fires is increasing: according to recent work in Cataloniabetween 42 and 138% for each area burned since 1992. The great debate of the future. As we have repeated on several occasions, there is no debate about the effect of climate change on increasing the risk of fire. The work is summarized in how much, how and where. Therefore, the central debate is another: what. What we do with the cards that nature is dealing us. And the truth is that there is a lot to cut: whether to bet on extinction or preventionif investing more in the landscape management or begin to integrate the entire territory into urban planning schemes more ambitious and extensive. Etc, etc, etc. The debate is endless and we are always late. Because what is clear thanks to Turco is that the distance that separates the spark from the megafire is increasingly shorter.

opening private clubs for Spanish millionaires

by

Madrid boasts of being a welcoming city for people from all over the world. That hospitality and its fiscal laxity with big capital have transformed the accent of some of the upper neighborhoods of the capital with the arrival of millionaires from all over Latin America. In fact, such has been the migration to the capital that some of the local millionaires have been displaced to other neighborhoods. As response to that massive arrivallocal millionaires have found a new way to socialize: select clubs for wealthy members, with five-figure entry fees and selection processes that are more reminiscent of a job interview than a place to socialize. Only in the last two years have they opened Forbes House, the Metrópolis Club in the iconic building on Gran Vía, the Vega Members Club and Soho House is about to arrive. Select and controversial club. Normally these spaces maintain a low profile and their openings do not appear in big headlines. However, the waiting list to enter some of them begins even before they open their doors. Remembering the scene from Brad Pitt in Fight Club: “The first rule of Fight Club is not to talk about Fight Club.” However, this silent phenomenon has made headlines after the statements by Tamara Falcó’s husband, by Íñigo Onieva collected by The World during the presentation of his club Vega Members Club. “We don’t want this to become the Latin American club either. We want there to be a balance between the local and international community,” Onieva said during the event. The comment seems to have not been well received by the Latin American millionaires living in the city, and has become an issue with economic, social and even political implications. The Latin response was immediate. As published The CountryOnieva’s statements quickly circulated among the richest and most influential Latin personalities in Madrid, generating surprise and indignation. Sergio Contreras, a Venezuelan political refugee in Madrid, goes further by reminding the managers of those clubs that some of those Spanish fortunes were made thanks to the fact that they emigrated at the time to countries like Venezuela. “There is a racist discourse that I am beginning to notice: first it was said that we took away their jobs in the real estate sector. Now, it turns out that we also steal their leisure and their apartments,” he complains. Manuel Campos Guallar, partner and co-owner of Vega, came forward to emphasize that different generations mix in these clubs, nationalities and professional profiles. For his part, the director of Forbes House, Andrés Rodríguez, was more direct: “We meet in the restaurants in Madrid, we meet in the stores, but we still don’t know each other very well nor are we doing much business,” he declared to the same medium. For Rodríguez, precisely connecting the Latin American community with the Spanish one is one of the missions of his project. Entering costs money, but above all contacts. Beyond the controversy raised by the right of admission by nationality, the new private clubs that have proliferated in Madrid are not exactly cheap, but money will not give you the key to enter either. Entering Forbes House or Vega does not depend only on being able to pay: there are interviews, filters and the mandatory recommendation of at least two current partners or the express invitation of the founders. Entry fees to these exclusive spaces are usually between 10,000 and 15,000 euros, to which must be added an annual fee that can exceed 2,000 euros. In the specific case de Vega, the founding members contributed 15,000 euros each and the annual fee is 2,400 euros and 1,500 for those under 35 years of age. The model was not born here, but it has found its moment here. Madrid has not invented this type of exclusive access clubs for select members. New York has been living for years The New York Times christening as “member-only mania“. A survey GGA Partners’ 2023 report reveals that 63% of clubs reported an increase in membership from 2022. Remote working created a class of well-paid executives hungry for a social life, and empty buildings after the pandemic provided the infrastructure necessary to satisfy it. London has been at this longer. The historian Seth Alexander Thévoz documents in his book ‘London, Clubland‘ a total of 133 active private clubs in the city, of which 78 are after 1985 and most of the newer ones have opened after 2015 or even 2022. Madrid is following that same path, with a small nuance: here the tension between the local and the international has given the phenomenon a charge that goes far beyond the economic filter to elect the wealthiest members of the city. The passport can also affect your income as a member. The business behind the phenomenon. Beyond the social nature of creating a space where millionaires from the capital can interact among equals, the proliferation of private clubs in Madrid is not a passing fad or a whim of four rich people: it responds to a structural transformation of the city. According to the latest report From Barnes City, the Community of Madrid leads foreign direct investment in Spain, concentrating close to 70% of the national total, with more than 24,000 million euros, and in 2026 it will repeat as the most attractive city for high net worth. That concentration of wealth It directly feeds the demand for exclusive leisure spaces for those ultra-rich clients. The business model of these private clubs for the rich is not new, but its scale is. He Club Matadorone of the oldest of this new cycle, has around 2,500 members and an approximate turnover of six million euros per year, with an annual membership of 1,720 euros. He New Clubof nineteenth-century essence and founded in 1856, has a maximum of 500 members, a permanent waiting list and a monthly fee of approximately 1,500 euros. The death of a partner is usually the only way of access for a new partner, … Read more

A website has collected more than 1,000 speed limitations on Spanish trains. Adif has knocked her down

by

They are called Dignitat a les Vies and they say they are “fed up with the mistreatment by Renfe, Cercanías and Adif.” The claim is clear: “we want a decent railway system.” And as a means of protest they had a website with all the speed limitations found on Spanish railways. They had it, because Adif has taken down the website. Cessation of activity. It is the title that heads a writing from Dignitat a les Viesa platform that until last Friday had an active web page in which all the speed limitations of Spanish railways were collected. The text reads that Adif has confirmed that the blocking of the page is derived from a previous complaint on its part, understanding that “the information on Temporary Speed ​​Limits (LTV) is ‘sensitive’ and cannot be known by the general public.” Listening to the road manager, the court has ordered the blocking of the website. What was shown? Simply, all the speed limitations present on Spanish roads. Supported by users and, above all, by machinists according to The Country, The association had a map where more than 1,000 incidents were recorded. The map, which Dignitat a les Vies assures has been replicated by the media (such as its own The Country) and has not been removed, showed public information that Adif refuses to provide in what they describe as “an act of paternalism. According to these users, “Adif is failing to comply with the current legal framework. In accordance with Law 9/2025 on Sustainable Mobility, Regulation (EU) 2017/1926 (MMTIS) – updated by 2024/490 – and Directive (EU) 2019/1024”, which requires them to make public “the data on the infrastructure and its restrictions.” And they emphasize that showing them “helps the user understand chronic delays.” The restrictions. As reflected in the newspaper The CountryIn Spain there are currently more than one mile of temporary speed restrictions active. This means that there are more than 1,000 points where drivers must circulate at a speed lower than the maximum speed permitted at that point in a generic manner. These restrictions are a consequence of actions on the tracks but also the consequence of continuous warnings by train drivers. And it is that, as they have confirmed to Xatakathe workers indicate with a report points that, in their opinion, should be reviewed or do not allow driving at the maximum speed required. Everything indicates that, after the Adamuz accident in Córdobathe zeal with these notices is greater than before. Train drivers also have the power to reduce speed at specific points if they so deem it necessary. These speed reductions must be reflected with a notice to the command post and in a report but, as we said, Adif has the final say on what is reviewed, what point is left for later and where speed restrictions are applied and for how long. Is it important? Yes, because temporary speed restrictions have multiplied high-speed travel time. Right now, Adif has indicated to the operators that Journey times are going to be longer in Madrid-Barcelona due to actions on the tracks and trains have been eliminated. This situation will last for months and as it is an issue that falls on the side of the road manager, the client has no right to compensation. The data of The Country They indicated on March 9 that there are 422 points where trains must run at a maximum of 30 km/h. It is the most repeated speed limitation. If the restrictions at 60 km/h or less are added, there are more than 850 points in Spain where high-speed trains cannot go above this speed. Where are there more limitations? Due to the volume of traffic and passengers, it is logical that the restrictions in Madrid-Barcelona have focused attention. Especially since it has been difficult to travel between both cities during the day without suffering any surprises or being clear about what time you are going to arrive, which complicates the traditional movement between cities. However, the media reports that line 100 Madrid-Hendaya is the most affected with 83 temporary speed limitations that reduce speed by 112 kilometers along the total 641 kilometers, followed far away by line 400 Alcázar de San Juan-Cádiz, which totals 85 limited kilometers spread over 69 restrictions found along 577 kilometers. However, it is the line 240 S. Vicenç Calders-L’Hospitalet that is most affected if the number of kilometers with active speed limitations is taken into account. And of the total 71 kilometers of the line, 56 of them have limitations below normal as a result of 35 conflict points.

Spanish cities are collapsed because they were not designed to go “from the periphery to the periphery”

by

For decades, commuting to work in large Spanish cities had a clear logic: workers lived on the outskirts of large cities and They traveled every morning towards the center to their jobs. It was a fairly stable urban model, reinforced by transportation networks designed to take workers to the large office districts of the urban area. However, in recent years this pattern has been changing as the price of land in the center has skyrocketed and companies have also had to move to the periphery. As and as it portrays The Countrythe problem is that cities are not designed to move from periphery to periphery, and that movement has become in a daily mousetrap for millions of employees. In recent years, many companies have chosen to move your offices to peripheral areas where land is cheaper and there is space to build large office complexes. This movement has made it possible to build huge business campuses that would be unviable in the urban centers of large cities with high demand for land such as Madrid or Barcelona. In Madrid, the north of the city has become one of the main destinations for this type of projects. An example is the Telephone Districtlocated in Las Tablas, which occupies about 22 hectares and concentrates more than 12,000 workers in a single business complex. The records of the Residence-Work Mobility Atlas of the Community of Madrid show that districts such as Fuencarral-El Pardo (where the Telefónica District is located) are already among the areas with the highest concentration of employment in the region. Barcelona experienced a similar process with the development of 22@ technological district in Poblenou, where numerous technology companies and corporate headquarters have been setting up shop in the last two decades. The transformation of this old industrial neighborhood created a new employment center outside the historic center of the city. Employment is moving, but so are prices The problem with this migration of companies to the periphery of urban centers is that when thousands of workers begin to concentrate in a specific area, the real estate market usually reacts quickly. Proximity to work centers increases the value of neighborhoods nearby, which ends up raising rental and housing prices. This increase, in turn, forces employees to move to municipalities even further away from the city center and the offices where they work. The result is a constant increase in daily trips within the metropolitan area. In Madrid this phenomenon is reflected in the labor mobility figures. According to the recorded data According to the Mobility Atlas of the Community of Madrid, every day 1.2 million people enter the capital from other municipalities to work, compared to the 790,000 who did so in 2016. Something similar is happening in the city of Barcelona, which after the growth of 22@ has attracted workers from numerous municipalities in the metropolitan area, congesting the northern and southern access roads and the city’s ring roads due to the traffic generated by these employees at peak hours, such as and how collect traffic congestion report of Inrix of 2025. All these congestion problems have their origin in the fact that the large transport infrastructures (metros, trams, Cercanías, bus lines, etc.) of the large Spanish cities have been designed for decades with a radial structure. They were planned to connect the peripheral neighborhoods with the city center, which was where most of the employment was concentrated. When new business centers began to grow outside the center, that structure began to show its limitations. Many workers no longer need to go to the urban area, but rather travel between peripheral areas that are not directly connected by public transport. A very clear example of this is the demand of the residents of Tres Cantos for an axis that connects them with… The A-6, not with the center of Madrid. This requires long journeys or several transfers, something that often makes the car faster. Even if it means getting stuck every day on the way to work. Furthermore, public transportation in many cities has become a lottery with constant delays and breakdownswhich generates uncertainty when considering alternatives to the private car. The increase in long trips to work and dependence on the car is clearly reflected in traffic data. According to the TomTom Traffic IndexMadrid registered an average congestion level of 38% in 2025, which is 3.6 percentage points more than the previous year. That level of traffic means that traveling 10 kilometers during rush hour can take about 34 and a half minutes, at average speeds. close to 17.5 km/h. The report also estimates that Madrid drivers lose around 98 hours a year in traffic jams during rush hours. When daily journeys are long, the accumulated time can multiply and reach up to 500 hours per year per person lost in traffic jams. Barcelona faces a similar situationwith a level of congestion in its urban center and access roads of 41.1%, which is one of the highest figures in Europe.

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.
