warning

has built a 152 -meter floating warning to the rest of the world

by

China has just signed a new chapter in the global race for renewable energy. This time, it is not an oil platform emerging in front of its coastbut of a floating wind turbine of huge proportions. A structure so massive that its blades exceed the height of most Spanish skyscrapers, designed to resist typhons and float in deep water. More than a technical advance, it is a strategic statement: the country not only wants clean energy, wants to control it from its own shipyards. Uploading the bet. The Asian giant has presented The most powerful offshore wind turbine in the world. The unit, with a capacity of 17 megawatts (MW), has been developed by the state of China Huaneng Group and Dongfang Electric Corporation, and has left the production line in Fuqing, coastal city of the province of Fujian, According to Global Times. Test process. The turbine will be towed soon to the waters of Yangjiang, in the province of Guangdong. From Esdnews They have detailed That the scale of the new wind turbine reaches 262 meters from the rotor diameter, a record that allows it to sweep an area of 53,000 square meters. Its height to the axis rises to 152 meters. According to figures from the Huaneng Group itself collected in the same medium, a single unit can generate up to 68 million kilowatt-Hora (KWH) of clean electricity per year, sufficient energy to supply about 40,000 homes. Not everything is the size. Although yes, since the wind turbine has been designed to withstand extreme maritime conditions, including waves of more than 24 meters high and winds of category 17, with speeds greater than 200 km/h, as They have collected in Chinadialy. In addition, it has an advanced stabilization system and smart sensors that allow maintaining production even when the platform suffers significant inclinations. It is not the first time that China Explore this technology. Last year, the Mingyang company installed Oceanx, a 16.6 MW floating wind turbine with double rotor, designed to resist hurricanes of category 5 and waves up to 30 meters. Located in Guangdong, Oceanx was a pioneer in extreme efficiency. However, the new Huaneng and Dongfang Electric model exceeds it in power, in size and in annual generation, with 68 million kWh, compared to the 54 million Oceanx. More than a giant turbine. This project fits a broader strategy that seeks to reduce the technological dependence from abroad. According to Global Timesall the main components – palas, generators, converters, transformers and even a new high diameter axis bearing – have been designed and manufactured in China. In addition, the turbine allows access to a resource so far used: the wind in deep water. In those areas, where it is not possible to install fixed structures, the only option are floating platforms. According to the Energy Research Institute of the National Development and Reform Commission, these areas have between three and four times more wind potential than the less deep coastal regions, According to China Daily. Float to get further. The Chinese advance is part of a global energy transformation. According to the World Wind Energy Council (GWEC)more than 80 % of the planet’s marine wind potential is found in waters of more than 60 meters deep. In this context, the development of large -scale floating platforms and national production places China in a leadership position. With a renewable capacity installed of more than 2,090 GW in May 2025, the Asian country already obtains one in three kilowatts-Hora from clean sources, such as Global Times explained. And keep accelerating. The wind as a flag. The new Chinese floating turbine is not just an engineering feat. It is a declaration of intentions. It represents the convergence between technological ambition, industrial sovereignty and ecological necessity. In a world that still seeks how to mitigate the climatic crisis without sacrificing development, China seems to be saying: the wind blows in our favor, and we know how to take advantage of it.

Someone records them without warning and nobody knows what to do

by

There is an awkward moment that is becoming common in meetings, face -to -face or online: someone enters the meeting, opens the laptop and without saying anything activates your Bot of ia To record and transcribe. The rest is silent, calibrating whether to protest or pretend that nothing happens. Thinking if you have enough hierarchy to raise your voice or if you will pay. Welcome to the era of normalized corporate surveillance. As usually happens, Technology has arrived before the rules. IA attendees can record, transcribeanalyze the tone, identify who speaks more, make inferences about us and even suggest answers in real time. But nobody knows what to do with that socially. Is it bad education to activate a Bot without warning? Where are that data? Who else will know them? What are they going to process with them? Is The classic paradox of all technological disruption: The tool exists, it works, promises efficiency, but the social norms are three steps behind. As when the mobiles arrived and it took years to decide whether it was acceptable to answer in the cinema or speak in the elevator. With the finish line we are living something similar. Only This time the risks are greater. Because the Bot Not only record: interpret, analyze, store. You can capture not only what you say, but how you say it, when you doubt, who you are more or less agree. And all that is registered in the other party, but also in servers of companies that already know too much about us. The solution will not come from technology, but from us. We need to quickly develop a clear label: Notify before recording or inviting the Bot. Specify what information will be used for. Ask if someone feels uncomfortable. Normalize company policies that restrict them, at least those of certain types. If we do not, We will end up normalizing that any conversation can become data to treat Without our consent. And that is not a meeting we want to attend. In Xataka | If the question is what recruiters are set when hiring, a study has given the answer: experience and attitude Outstanding image | Xataka

Our reservoirs have a serious structural problem. And experts have been warning us for years

by

Drought has been one of the recurring themes of recent years. Both the lack of rains and their diverse consequences have more than a five years in the informative agenda. That is why the question of how much water we have left has asked Very diverse ways. There is only one problem: we are not really able to answer it. Moreover, what we know that our water reserves They are usually below what the data indicates. The reason is in something as natural as erosion and sedimentation processes, but its consequences They have been worrying the experts for years. Throughout their channel the rivers transport small particles of rock and organic matter that tend to accumulate at certain points of the route, either on the river bed, in river deltas or in its meanders. The reservoirs are another of the auspicious places in which the water tends to “release” these particles. The swamp floor Thus tends to accumulate sludge. The first problem that this generates is the loss of swamp capacity. The higher the volume of this occupied by sediments less is the amount of water it can store. The second problem is that we do not know exactly how the sediments accumulate in each swamp since it can vary depending on the characteristics of each basin and each reservoir. If we don’t know how many sediments we have, we can’t be sure how much water we have left. The weight of the terrams Estimates on the weight of the terrain, which is how this accumulation of sediments is known in the reservoirs, vary. A Batimetry Study made in 2018 For the Tajo Hydrographic Confederation in the Entrepeñas and Buendía reservoirs, he estimated that the accumulation of these sediments was insignificant. At the opposite end, Another batimetry studyis made by the Segura Hydrographic Confederation, estimated that its reservoirs could have lost between 10 and 40% of its capacity due to the incidence of this phenomenon. They highlighted the case of the Lorca reservoir, built at the end of the 19th century, which would be at the upper end of this fork. Estimates made for the whole Spanish reservoirs are limited. A study conducted from 110 reservoirs estimated that The loss of capacity could be around 5%. José Luis Casamor and Antoni Calafat, from the University of Barcelona, They warned in 2018 that uncertainty was high in this estimate, since the possibility of extrapolating the results of this study to more than a thousand remaining reservoirs was limited. This is a problem on which experts carry years warning. The study carried out in the Segura Basin, for example, was carried out in 2017, while Casamor and Calafat’s work was published in 2018 in the publication Earth and technology of the ICOG (Illustrious Official College of Geologists). In a second article (also published in 2018) in The conversationCasamor explained that that of terraces was a problem with “faces and difficult execution” solutions “. Cleaning the sediment reservoir bed is an arduous task that requires the emptying of the reservoir, something that can be even more complicated in old reservoirs, explains Casamor. Prevention is a better option for this expert. This is to incorporate knowledge about the accumulation of sediments in the infrastructure design process. Another inclusion of dikes prior to the reservoir may contain the sediments up so that they do not accumulate in the reservoir. Other proposed measures to contain the sediments upstream include reforestation. The plants contain the erosion of the soil, which makes less particles reach the rivers and from there to the reservoirs. In this sense, rural abandonment has also been indicated as partial responsible for the situation. The fires also contribute to the arrival of sediments to the channels, so the fight to contain them can also contribute their grain of sand.

The Switch 2 comes with a protector that many would remove without thinking. Nintendo has a warning for users

by

One of the first gestures we usually release a new device is to withdraw the screen protector that comes from the factory. It is almost an act reflex: remove the bright movie, place a more robust temperate glass and, if it is a mobile, sheems it to protect it from blows. But with the Nintendo Switch 2that custom can play against. This time, what seems like a simple protective film is not there for aesthetics or courtesy. Nintendo has made it clear that it is not convenient to withdraw it. And he has done it even before the official launch of the console, scheduled for June 5. The notice appears in the security manual that will accompany the device on its arrival to the European market. The document, already available on the official websiteincludes a very clear warning: the screen is covered with a movie designed to prevent fragments from being dispersed in case of breakage. The exact phrase, in Spanish, is direct: “Do not withdraw.” Nintendo’s warning, as appears in the official manual This may sound strange if we think of other technological products. After all, we have been getting used to this type of film for years, almost a wrapping. But not here. In this case we talk about a layer with a concrete security featuresimilar to the one that already incorporated the Nintendo Switch Oled. In that device the same target had: prevent cuts and prevent pieces from jumping. The previous consoles did not have this protection. The Original switch and the Lite They used plastic screens and, therefore, did not present that risk. But the change to glass screens has forced Nintendo to take action. It is not just a change in the material, it is a decision that impacts the use, safety and how we should treat the device as soon as they get it out of the box. And it is not something exclusive to Nintendo. In the world of smartphones we have already lived a similar situation. The most remembered example was the Galaxy Fold Samsung original. That first niche of folding mobiles included a layer that many confused with A simple protector. When they withdrew it, Some experienced problems. Not everything that looks like an accessory is. Sometimes, it is part of the device itself. Returning to the Switch 2, the advice is clear: it is convenient not to touch what we do not know exactly what it is for. And even more read the instructions. Because this console, which will cost 469.99 euros (VAT included), it is not precisely a cheap investment (Like your games). Risking to spoil the screen for an automatic and avoidable gesture is not worth it.

Meteorologists have been warning that southern Spain would reach 35 degrees this Sunday. The Sahara had another idea

by

Sunday was going to be the key day: the moment when the country, after a very rare spring, was going to receive the first summer bars. By the south, Claro: Seville was directly at 35 degrees and Córdoba would not come down from 32. However, something has changed. Why was I going to make so much heat? For an old acquaintance, an anticyclonic dorsal that is installed on top of our heads and, without wind or clouds, makes temperatures begin to shoot: the Iberian oven. It is the same configuration that causes us the frequent heat waves that visit us every year. The dorsal will continue here, but its effect will be much less than expected. And the fault is a Dana. As the Dana that was in the Atlantic approaches the Portuguese coast, it will displace a huge tongue of Saharian dust that will enter the southern and southeast peninsular. As Nacho Espinos explained And as we have seen on other occasions, the suspension dust “reduces insolation and limits the values” that the thermometers can reach. That does not mean that it will not be hot. Of course it will be hot. Above all, if we compare them with the first two weeks of May. Not only can up to 32 degrees be found in the heart of the Guadalquivir Valley, but many parts of the country will be above 30 degrees. But the 35 degree psychological limit is not going to be achieved. And that the environment will be very murky. It is not necessary to remember that the abundance of dust in suspension, worsens air quality and can generate mild respiratory problems (from mucous irritation or nasal obstruction to itching in the eyes or dryness of the upper respiratory tract). In areas with a very strong calima complications can be greater. Above all, in people with previous ailments. According to The works of the University of La Lagunaup to “2% more people die from heart disease the two days of the phenomena of Calima.” What can we expect? A summer that does not end up landing, even if it is closer. That and A bad air quality. Above all, because to the extent that blockages in Europe continue, the arrival of storms, danas and cold storms can continue an almost indefinite time. That 2025 is strange We have it clear. How strange it will become, It is still to investigate. Image | Copernicus In Xataka | May is putting a March face: Aemet’s great question is if 2025 will definitely end the drought
