The problem with Tesla Cybertruck is not its price, you don’t know if it comes direct from a field

by

The story of Reza Sostani is the best summary of the Tesla disaster with his Cybertruck. A Texan client that took only one day to return it after buying it. The reason? He acquired the Tesla Cybertruck on April 25 and, just a few hours later, the vehicle was ready for collection. This immediacy in the delivery, despite what it might seem, is bad news. The Lostani case. Relatani says He is one of the buyers of the Cybertruck in Tesla. On April 25 he made the order of the car, surprising after the immediate allocation of Vin number (number of identification chassis of each vehicle) and notification on the same day that his car was prepared for the collection. Different, he decided to ask Tesla from where the vehicle came from and how it was possible that he was ready. The Tesla representative he consulted soon in giving him the news: his cybertruck had left the factory on January 8. The Cybertruck and their dates. Buying a vehicle that has been manufactured for a few months has an immediate translation: stock accumulation. In the case of Tesla this is especially relevant, since its models usually have high demand (Model 3) and it is common for stock units to have a few weeks old. If we take into account that it is an open secret that Tesla is accumulated outdoors thousands of cybertruck that He can’t sell for monthsthe rejection of the buyer to one with four months is more than understandable. Manufacture and park. That a vehicle spends four months stored in a campaign is not the best for your health. In the case of an electric vehicle, it is especially relevant, since the battery storage temperature, its load level, air ventilation to avoid moisture, possible oxides … Everything influences. One of the photographers of Tesla’s gigafactories published in X, without giving much more data about itthe image that shows dozens of cybertrucks freshly production. Some of them were ready to be delivered, others would remain waiting for owner. Tesla Model 3 highland that had not yet been sold, stranded in fields Hundreds of tesla not sold, stacked in another field. The problem with the fields. The problem is that, on more than one occasion, He has hunted Tesla accumulating in Campas Hundreds of without selling vehicles. And, yes, there will be some lucky owner who ends up sending one of the Tesla who has been outdoor months. It is not a car to play it. The maturity that Tesla has achieved by refining the manufacture of Model 3 or the Model and It is quite far from the Cybertruck historic. This electric truck has a terrible depreciation For their very high repair costs, their numerous call calls and the various problems associated with its manufacture. It is predictable that the potential customer of a Cybertruck is new, something that clashes frontally with the gigantic vehicle park without selling that Tesla has now in its factories. More manufacture than sales. This excess stock responds to a basic: Tesla has manufactured many more cybertrucks than its public demands. So much, that the company is starting to lower the price drastically and open to new markets, such as Saudi Arabia, to stabilize sales. Last April we had news about an inevitable response to this situation: Tesla is beginning to reduce the production of the Cybertruck and reducing up to half some of its production equipment, According to Business Insider sources.

Having solar panels at home sounds very good in case of national blackout. The problem is that they don’t work

by

The national blackout that Spain has suffered It has been historicalbut has also sown the doubt. While the vast majority of citizens ran out of light, in the street there was “life” in some supermarkets or marques that made the use of other renewable alternatives. Surely also, today more than ever many will ask about the need to have a solar installation in their home, which leads us to another question: how does a network of domestic panels work before a national blackout? Installation in normal conditions. Before talking about the case of a blackout as the one that occurred in Spain, it is convenient to explain the most basic of A “standard” installation In a typical home. In most cases, solar panels capture the radiation of the sun and generate what we call DC (DC). This current passes through an investor that converts it in turn in alternating current (CA), and that is precisely what we use in homes. In Spain and in almost all countries, most solar facilities are connected to the electricity network (known systems as on-Grid). This allows, on the one hand, to consume solar energy directly in the house. On the other, pour the surplus to the network (which entitles economic compensation, such as the net balance or Simplified compensation). Finally, of course, it allows you to receive electricity from the network when there is not enough solar generation (for example, at night or on cloudy days). The problem occurs when there is a situation like that occurred yesterday. Installation in blackouts. When you have a photovoltaic installation in the house of only panels and there is a blackout, something contradictory but very important happens: even if you have solar panels working, the sky is sunny and the beginning of the day, your house is also It is left without electricity. As? Yes, this occurs by security regulations (for example, in Europe under the standard VDE 0126-1-1 and similar), all solar investors connected to the network must detect the loss of tension and turn off immediately, is what is called Anti-Isla protection. The reason? The reason for this “cut” is to protect network maintenance technicians: if there were thousands of houses by sending electricity to a supposedly “dead” network, it could be lethal for workers They are at that time repairing the failure. Therefore, if you have only solar panels connected to the network, you cannot use electricity during a blackout. Your solar panels are automatically disconnected. There is no more. The solution: batteries. If you also have batteries, the thing changes, although here the situation varies depending on the type of investor and configuration you have. If you have hybrid investors (solar + battery), there are modern investors that already allow to continue operating in what is called Island or back-up mode. This means that when they detect a blackout, they are physically disconnected from the network and come to feed only your house using solar energy and energy stored in your batteries. In addition, there are also systems for backup investors (The so-called back-up inverters), where a separate system is used that can feed a specific part of the house (for example, fridge, essential lights or internet). One More Thing. But even so, for this to work you need lithium or lead batteries properly sizeda hybrid investor compatible with operation in island mode or an inverter with backup function (Back-UP), a automatic cutting system that separates your home from the public network in case of blackout guaranteeing safety, and finally an electrical panel prepared to isolate non-essential loads (for example, it makes no sense to keep the electric oven or air conditioning on if the energy is limited). In any case and to place all this in perspective in the Spanish landscape, only 33% of facilities Current domestic lots in Spain include batteries. This means that most households with solar panels would continue to suffer electric cuts during a blackout like the one that occurred yesterday. The reasons are very varied, but the extra cost of investment of them after the solar installation (already large) is key. The promise of self -supply. All this leads to a final question: Is it possible to be self -sufficient (energetically) in Spain? The short response is no. The promise of solar self -supply on the peninsula is based on taking advantage of the high solar radiation (Spain receives on average between 1,600 and 2,000 kWh/m²/year) to generate clean energy and reduce dependence on the electricity grid, especially in single -family homes. Thanks to photovoltaic self -consumption and the Price drop Of the solar panels (more than 80% have fallen in the last decade), today it is technically possible to cover between 60% and 80% of the annual consumption of an average house in Spain only with solar energy, and in some cases, almost 100% If appropriate storage batteries are installed (although with the network hitch). The problem. However, self -supply has important limits: solar production is intermittent (there is no generation of night and lowers a lot in winter or cloudy days), the batteries remain expensive (between 4,000 and 9,000 euros a complete domestic installation) and its capacity only allows a few hours or days of autonomy without network. Plus: We already said it, the current legislation requires that the systems connected to the network be disconnected in blackouts if they are not equipped to function in Isla mode, which implies that, without a specific design (and of large disbursement), even with solar panels, you could run out of electricity in general cuts.

Renault asks Japan to copy and make “small cars that people can buy.” The truth is that we don’t want them

by

The automobile market has forgotten small and simple cars. It is a reality for which it should be a perfect mobility solution for the middle European citizen. Now, Luca De Meo is committed to prioritizing the “small cars that people can buy.” But do these words make sense? “We don’t do it”. Because they are “unproductive,” according to Luca de Meo. Of those who speak are of small cars, of those of smaller size that, for the CEO of Renault, have completely killed European regulations. “We have to make small cars that people can buy again,” he said in an interview with Auto.it. “It is difficult for a regulator to know more than an engineer which is the best solution. Let’s leave engineers the best solution to reduce the impact of CO2,” said Meo to the questions of the Italian medium. The problem? For the CEO of Renault it is clear: “European regulation in the last 20 years has failed.” And this has been because “it was driven by the Germans, who wanted to make the most complex cars, because it suited them. That has had a devastating effect in other producing countries such as France, Italy and a little in Spain where people buy small cars because they do not have money or do not enter the cities.” The solution? Have your own regulation that It resembles that of Kei Car Japanese. These cars are extremely small, they cannot exceed 3.4 meters long or 1.48 meters wide. Nor equip yourself with an engine greater than 660 cc or 64 hp. In return, cars are not considered as such and, therefore, They do not have restriction problems that traditional vehicles in large cities have. In return, MEO slides not only the idea of ​​promoting small vehicles with new legislation, it also chooses to reduce the mandatory safety elements in cars of this size. “We were forced to add a security equipment valued at 400 euros. That on a Renault Twingo is a lot of money, in a sedan it is much less.” Too expensive. It is a usual criticism of the price of cars. They are too expensive for the client to allow them. Actually, although in recent years the price increase has been very pronounced, a car is cheaper now than 50 or 60 years ago. However, the ability to access the low range has been reduced. Pressing for other expenses of enormous cost, such as housing, the Spanish average citizen is opting for low -end vehicles when acquiring a new car. In what we have been, The best -selling car is Dacia Sanderofollowed by the MG ZS, the two cheapest cars in its segment. He is accompanied by Nissan Qashqai who has recently dropped price and the Renault Captur and Seat Arona, cars that barely exceed 20,000 euros starting. It does not come profitable. In his words, Luca de Meo is part of reason. Match the cheapest cars in safety equipment with the highest cost Price irremediably increases of this type of vehicles. By European regulationsthe cheapest car that is sold in our continent must have, among other systems, emergency braking, lane output alert or rear camera. However, it is also unquestionable that this equipment is an extra security for drivers who put themselves at the controls of a car. Although from Dacia (from the Renault Group) They have removed value for these measuresthese types of obligations guarantee a minimum of possible accidents to all drivers. Do we buy them? Luca de Meo’s words sound very good but … are we interested? If we attend to the number of Enrollments in our countryurban vehicles (such as the aforementioned Twingo) barely register 1.4% of registrations. They are the compact and the C-SUV (comparable by size) the most purchased vehicles in Spain, accumulating 48.5% of registrations. A segment followed by the utilities and B-SUV, which total 39.6% of the enrollment. Expanding the views to the rest of Europe, Discriminate Acea to vehicles in traditional sizes. A+B for utilities and urban (those of smaller size), followed by compact (c), medium size (d) and luxury (e and f). However, take the SUVs out of these categories. According to these data, in 2023 segment A and B that De MEO considers among the best selling remained at 21%, while the SUVs accumulated 51% of the registrations (between three and four times more than a decade ago). The little ones (taking into account that they add two segments) are not so far from 15% that compact accumulate. Do we want them? It is the other big question. According to the registration, we prefer larger vehicles. But, in addition, there is another constant: commercial failures among smaller vehicles. Although most European citizens make their daily journeys in urban environments, cars dedicated exclusively to the city remain little dear. WE HAVE SMART EXAMPLEconsidered a car too expensive despite being extremely useful in the European cities of intricate streets in historical and difficult parking helmets.

In the middle of the commercial war, China has found a way to punish US exports. And you don’t need tariffs

by

In full electoral campaign, when there was still talk of A fierce duel With Kamala Harris at the polls, Donald Trump recognized during An interview In Chicago that the term you like most about Shakespeare’s language is Tariff (Tariff). “For me, the most beautiful word in the dictionary”, proclaimed. View The forcefulness With which China has responded to its commercial war, it could well think that “tariff” is also Xi Jinping’s favorite word, but the truth is that Beijing has its own way of hitting the US trade. A much more discreet than rates. Tax pulse. Trump did not exaggerate to proclaim his love for tariffs. And good proof is that in the almost three months it has been in the White House, it has launched more or less clear ads (and also the occasional Auto amendment) of rates aimed at steel and aluminum or The cars and its components. Also of course the bad calls “Reciprocal tariffs”embodied in the famous rate table that presented A few weeks ago in the Rosaleda of the White House, and those that already appear on the horizon for Chips and drugsamong others. With the passing of the days and after Trump Pausara much Of its tariffs for 90 days, the commercial war has basically enchanted between the US and China. Washington has decided to apply to Chinese imports rates that rise at 145%while Beijing has returned the blow to Trump raising his own 125%. That answer does not mean that the tariffs are the only tool to which the Chinese executive has resorted to face the US. After all … aren’t there other ways to stop imports? Who needs tariffs? The news He has advanced it The American magazine POLITICAL: Throughout the last four months, Beijing has activated a series of bureaucratic obstacles and agreements that have had a clear effect on the flow of US imports, reducing them from or even stopping them. The method is more stealthy than the tariff war (and perhaps does not inject the thousands of millions to the public coffers that Trump is looking for with the tariffs), but allows Beijing to hit the US at a sensitive point, its commercial exports. THE KEY: Non -tariff barriers. “A tariff pays and things are more expensive, this is a total restriction to the ability to send products to that country,” Ben Lilliston commentsof the Institute of Agricultural and Commercial Policy. It is not a minor note if the intense commercial flow between China and the US is taken into account, which in 2024 resulted in the export of goods to China by value of 143.5 billion and imports that amounted to almost 439,000 million. But … How do you do it? POLITICAL Quote some specific cases. For example, Beijing has decided Do not renew At the moment the export permits of hundreds of meat packaging plants and has claimed that some products derived from American chickens do not meet their standards. You don’t have to look much in the newspaper library news in that line. Does A few days The General Administration of Customs warned of the appearance of Furacilina, a substance prohibited in the country, in three lots of meat of US companies. Result: suspended its import. The Chinese organism took A similar measure With the sorghum products of an American company after detecting “excessive levels of zaralenone”, a type of mycotoxin. The decision was announced one day after Trump imposed a 34% tariff on Chinese goods, although Beijing insists in which the restrictions for technical reasons and objectives apply: “To prevent risks and guarantee the safety of livestock production and consumer health.” Are there more cases? Yes. ABC News recently He informed that some 300 US slaughterhouses have not yet renewed their export permits to move beef to China, which seems to have found a substitute in Australian livestock. Beijing’s reluctance to renew the licenses have in fact stopped a good part US rescor export. And that are major words. In 2024 the US exported to China worth 1.6 billion dollars. Another sector that has also been emphasized of turbulence is that of natural gas. At the beginning of the month, with the commercial war about to climb, Bloomberg revealed that China had no matter of US LNG 60 days. The scenario remembers the one who lived years ago, during Trump’s first mandate, when the Asian giant stopped receiving US shipments during Around 400 days. Citing Kpler data, POLITICAL assures that so far this year of China imported only a cargo of gas compared to 14 of the same period of 2024. Hitting where it hurts the most. Chinese restrictions not only affect US exports, with their corresponding impact on a flow that moves millions of dollars. By applying Beijing can point to concrete sectors, such as Lift POLITICALindustries rooted in states (Iowa or Nebraska, for example) that usually act as republican vote heshes and therefore can exert greater pressure on Trump. Something similar did A few weeks ago The Brussels when he planned his own response to the first USA tariffs. Bureaucratic obstacles and restrictions also force companies to move in slippery terrain, even more than that of tariffs. “We do not want health and security to become a political issue,” Darci Vetter argueswith experience in the US commercial representative office. “Convert carers carefully considered and based on science into a political issue.” Marc Busch, who has also exercised as an advisor to the US Department of Commerce, is even more categorical: “This is what China does: commercial actions disguised as legitimate public policies with a scientific basis.” Is it a new measure? No, not exactly. The Chinese government seems to have intensified restrictions that are not new and can even go back to Your entrance In the World Trade Organization (WTO), more than 20 years ago. The US is not the first country that is found with brakes to its exports that coincide with moments of tension with Beijing. It happened to him … Read more

The universe is becoming more chaotic and we don’t know why. The main suspect is dark energy

by

From the first moments after the Big Bang, gravity has shaped the matter, giving rise to the intricate structures that define our universe. Galaxies, galaxy clusters and galactic filaments have evolved in ways that They almost always agree with Einstein’s general relativity theory. But something does not fit. The universe is more messy. A Recent study Directed by cosmologists from the University of Pennsylvania and the United States Lawrence Berkeley National Laboratory points out that the universe has become “more messy and complicated” over time. There are fewer agglomerations of the subject that predict physical models. The research crosses two very different types of data observed by the Atacama Cosmology Telescope and the spectroscopic instrument of Arizona’s dark energy. Combining both maps, scientists discovered that almost the whole history of structure formation coincides with the predictions of Einstein’s gravity, except for a small discrepancy in the agglomeration of matter of more recent times; For about 4,000 million years. A cosmic tomography. To build a multidimensional vision of the cosmos, scientists started from the oldest light we can observe: The cosmic microwave backgrounda radiation from 14,000 million years ago, when the universe was only 380,000 years old. But the journey of this ancestral light has not been in a straight line. It has been diverting and distorting the gravitational attraction of mass structures such as galaxies clusters, a predicted phenomenon by Einstein and known as gravitational lens. Overcoming the map of these distortions with the distribution of galaxies has allowed cosmologists to infer how matter is distributed over time. “It’s like a cosmic computerized tomography,” said Mathew Madhavacheril, co -author of the study, In a statement. “We can look through different cuts of cosmic history and track how matter has been agglomerating at different times.” Something does not fit. The “agglomeration” of matter (measured by density fluctuations) seems to be slightly lower in the most recent times than the models predict from the early universe. Cosmic structures have been grouped less intensely than we expected. The researchers are cautious: it is a small discrepancy that could be the result of chance and not the test of new physics. However, if the deviation turned out to be A statistical anomalycould point to unknown physical processes that influence how cosmic structures are formed and evolved. One of the hypotheses is that It has to do with dark energythe mysterious force responsible for the accelerated expansion of the universe. Perhaps dark energy is affecting the formation of structures in ways that current models do not capture completely, acting as a powerful force that moderates the large -scale agglomeration.

We have been using sweeteners that provide zero calories. Now we understand why they don’t always help lose weight

by

Sugar is one of the most daily foods and one on which food controversies do not scarce. Excessive sugar consumption can be linked to various problems, from the oral to diabetes. The artificial sweeteners that we sometimes use to reduce the consumption of conventional sugars can be healthier, but no less controversial. Less sugar, more hungry. A recent study He has found that some artificial sweeteners could be affecting the signals that manage our appetite at the brain level. The team responsible for the study observed that the Sucralosa had a less satiating effect than sucrose, conventional or table sugar. The Sucralosa. Sucralosa is a artificial sweetenera disaccharide or compound sugar such as the union of two simple sugars. Its sweetest capacity is up to 600 times higher than that of sucrose, but our body does not absorb it in the same way. This implies that this sweetener has no caloric contribution to our body. This could explain the observed phenomenon: our body would perceive the sweet taste and prepare for calorie ingestion. The body would simply be responding to the absence of energy received. 75 participants. In the study, 75 participants who worked as both of the experimental group and control group in two sessions separate days or weeks from each other took part. Participants, men and women, some with “healthy” weight, others overweight or obesity, consumed three drinks prepared in the experimental sessions to which they underwent. These preparations were a sweetened drink with sucralose, another with conventional sugar (sucrose), and another simple water. The order in which they assigned each drink was random. The team later studied the participants’ response to each drink. Before and after the test they carried out functional magnetic resonances, they took blood samples and asked the participants for their feeling of hunger. They observed that the sucralose increased appetite and activity in the hypothalamus and that it did it to a greater extent among the participants with obesity. The team also detected changes in how the hypothalamus communicated with other brain regions. The details of the study were published In an article In the magazine Nature Metabolism. Old acquaintances. The key can be in the hormones that our body produces when eating, hormones such as insulin and LPG-1 (Glucagon -like peptide 1). This last hormone is produced in the stomach when we eat and fulfills a double function: on the one hand warns the pancreas that we will need insulin to manage digerida glucose; and by transmits to our brain the message that we have fed and satiated. “The body uses these hormones to tell the brain that you have consumed calories, to reduce hunger,” Explain in a press release Kathleen Alanna Page, co -author of the study. “The Sucralosa did not have that effect, and the differences in hormonal responses to the sugar compared to sugar were even more pronounced in participants with obesity.” Much to investigate. According to the team itself, there are still some unknowns to solve in this context. One question, for example, is how this sweetener affects our brain activity in the long term. To do this, they explain, longitudinal studies will be necessary that also analyze the weight and food behaviors of the patients. Another issue to solve is how other factors affect, such as sex, this relationship. The team indicated that during the experiment, the brain activity of women showed greater variability than that of men, which implies the possibility of differences to study.

There is a relationship between eating fruit, drinking coffee and the risk of tinnitus. But we still don’t understand where it comes from

by

The human body is a very complex machine in which millions of interactions are produced, some intuitive and direct, others that are neither one nor the other. This sometimes implies that we find correlated phenomena after which there could be causal relationships that we are not yet able to understand. An example of this in a curious connection that unites our digestive and auditory system. A new study. A Chinese researchers team He has studied The relationship between certain foods and the risk of suffering tinnitus. The team found that greater consumption of fruits, fiber, dairy and caffeine were linked to a lower risk of suffering from this annoying disorder. The ears. Tinnitus It is nothing but a technical term with which we refer to the sensation of buzzing or beep we perceive in the ear. A noise that only exists in our head and that can be presented in a diversity a wide range of shapes, each with different characteristics, some of them very annoying and difficult to treat. These forms They have diverse originssuch as age loss related to age, possible ear injuries, or circulatory system disorders. It can manifest intermittently or permanently, and it can also be intense enough to interfere with our audition or limit our ability to concentrate. Meta -analysis The notion that there is a link between some foods and the risk of suffering tinnitus It is not new. Various studies can be found that have previously investigated in the field but drawing conclusions from this literature is not easy. That is why the team responsible for the new work carried out a study of this scientific literature, a review of literature, from which it carried out a quantitative analysis of the results identified in this, that is, a meta -analysis. The team compiled and analyzed the results of eight studies which accumulated a total of 300,000 participants. They analyzed the effects of 15 dietary factors on the risk of appearance of this auditory disorder. Different foods, different impacts. The study estimated from these eight previous works that greater fruit consumption could be linked to a 35% reduction in reducing the risk of tinnitus. The reduction associated with greater dairy consumption was 17% and that of the caffeine of 10%. They also observed a 9% reduction in the probability associated with the highest food fiber consumption. The details of the study were published In an article In the magazine BMJ Open. Prevent yes, cure right? The results are striking, but the interpretation is complex. The reason is that We have no clue on the hypothetical cause and effect connections that could be behind this relationship. That is, we can observe correlation but we cannot infer causality. Another track on this connection is found in another review of the literature made a few years ago. Posted in 2020 In the magazine International Archives of athinolaryngologythe work also observed a link between caffeine and tinnitus but warned that it only occurred preventively: that is, it observed that caffeine consumption was linked to a lower risk of suffering from tinnitus but a greater consumption of the substance did not serve to improve the state of those who already suffered the problem.

In the emptied Galicia there are municipalities taking care of gas stations and shops. THE OBJECTIVE: Don’t run out of services

by

The Emptied Spain It is depopulated Spain, but also the one that is emptied from companies and services. Both, the Lack of neighbors And the absence of businesses that cover their most basic needs, are part of the same vicious circle that in the long run the peoples to abandonment. In Galicia They have decided Breaking that loop with a curious movement. To avoid running out of supermarkets or gas stations there are municipalities that are taking care of their management. The objective: that the neighbors should not move kilometers for something as simple as buying the bread. Even at the cost of the City Council itself assume private services. The ghost of depopulation. The depopulation He is one of the great ghosts of the rural of Spain. And Galicia is no exception. A few months ago his Consello de Contas He issued A report in which he warned that in the community (especially in the provinces of Lugo and Ourense) there are almost a hundred towns in ‘danger of extinction’, a status that is explained by a combination of factors: a register below the 5,000 inhabitants, a low population density (less than 20%) and more deaths than births. INE himself calculates that in 2021 there were almost 25,700 Gallegos residing in municipalities that do not pass from the thousand registered. According to his nomenclator, in the community there are also around 1,900 depopulated villagesmany of them in Lugo. Only in 2023 it is estimated that the province lost about 40. Other populations are still alive but with a handful of hundreds of neighbors and having lost much in a short time. To name a case, Murasin the Terra Cha, I had 1,151 neighbors In 2000. In 2024 were 600. A vicious circle. We commented before. The localities of emptied Spain do not remain alone without neighbors. They often do it also without businesses that cover their needs. And one and the other, that of inhabitants and services, feed a vicious circle that ends up accelerating the emptying of the peoples. Although there is experts That they conclude that at general “accessibility to services” in Spain is good, especially if we talk about health and education, they also recognize that differences arise when the provincial scale is lowered. A quick search arrives on Google to find Complaints of populations about the public transport or lack of something as simple as bars and shops. And how to solve it? A question similar to that was asked a while ago in Pol and Ribeira de Piquíntwo localities of the rural of the province of Lugo that together barely go from the 2,000 residents. The first, Pol, has 1,542 registered, 27% less than in 2000. The second, Ribeira de Piquín, had about 500 residents, 80% less than at the beginning of this century. Both municipalities share Another featurein addition to the province and a diminishing census: given the loss of basic businesses their respective municipalities have decided to step forward and guarantee the continuity of private services. A kind of municipalization which aims to prevent your neighbors from having to look for life for issues as basic as buying bread. Their cases have attracted the interest of media such as The voice of Galicia either Eldiario. A “municipal” supermarket. In the case of Pol the Consistory he found the risk that The only supermarket From the town, located in the population of Mosterio, closed. Its owner retired and in the absence of relief or other shopkeepers that would like to transfer it, the panorama was complicated for the neighbors who reside there. “No one was interested in carrying it. It was deserted,” explained in December Its mayor, Lino Rodríguez, Progress. The City Council solution: Buy the super To keep it open. It is not yet known How will it manage, through a foundation, attracting a franchise or with an autonomous, but the goal is clear: to guarantee the continuity of the service. “We acquired the entire block, which has an area of ​​about 800 m2, for a total of 150,000 euros,” Rodríguez added In December. The project went ahead with the support of the Diputación and aspires to go beyond trade: Pol wants to recover an old sausage mark and create social housing at the top. At the end of last year the town had already paid 75,000 euros for the premises, it hoped to pay a similar sum of 2025 and already thought about furniture and facilities to serve customers. “We need to acquire the material goods of the interior, such as refrigerators, freezers and cold cameras. But throughout 2025 we will try to prepare the charcería,” He reported. OBJECTIVE: Refers in the town. In Ribeira de Piquín, the City Council has also moved to preserve a key service, although in this case the focus is on a gas station. At the end of 2024 the Consistory was in process for rent an already built service area but it carries more than a decade closed The idea is reopen it in 2025 and that the neighbors do not have to move to another town to replace or look for fuel. The project is carried out through the Terreo Foundationparticipated by the City Council, and with support of the Diputación de Lugo, which provides funds through an agreement. The rent will be done through a direct award procedure, Precise Progressand once completed the idea of ​​the City Council is to adapt the station to the regulations to register it. In the budget they also reserve funds to hire full -time personnel who can take care of the suppliers and serve users. Is it an isolated case? No. The gas station will not be the only (or first) project that is promoted with the terreo lever.
