Hesai was an unknown Chinese giant in Europe. His alliance with Mercedes is about to change everything

by

When we talk about large car manufacturers we can fall into the error of thinking about a vehicle as a whole that Renault, BMW, Citroën or any of the Chinese brands that intend to take a place in Europe. But nothing is further from reality. A car is the sum of many small parts. Specific parts of a combustion engine, braking systems, suspensions, seats … Many of those parts, so evident, are not manufactured or produced by large vehicle manufacturers. Bosch, Recaro or Brembo will sound, for example. In fact, Chinese manufacturers who are arriving in Europe or point to it, like Xiaomi, have not hesitated to associate (and show off this) with great more than recognized suppliers in the car market. In their presentations, Byd or Xiaomi have highlighted the role played by companies such as The aforementioned Brembo in the components that ride in their cars. It serves to gain credibility to the most skeptical. But when talking about another type of technology it is Europe that looks at China. Byd, for example, get great prices in its vehicles because It bases its production on verticalitymanufacturing their own batteries but also their own semiconductors or heat pumps. Among that “other type of technology” we can put Hesai. The Chinese company is the largest laser sensor producer. And now he has reached an agreement with Mercedes. From China to your Mercedes As vehicles have gained acting, they have also been growing in complexity. Although Tesla has made it clear that he wants to base all his autonomous driving functions or, as little, for driving in the use of software, at the moment it is still clear that cars armed with laser sensors and other radars are still safer and more effective. To achieve the best result, Mercedes has reached an agreement with Hesai, which triggers its possibilities to grow economically and reach new agreements with other companies explain in South China Morning Post. And it is that Hesai will supply radars lidar to the German company to map with better accuracy what their cars are around. In Reuters They explain that the decision has been weighed for months by the German company but, finally, costs have been imposed on any other value. Keep in mind that the sensors supplied by Hesai may not be used in Mercedes cars that are sold in the United States from 2029 if the intentions of Prohibit the sale of every car with Chinese pieces in the country. The use of Lidar sensors It is especially delicate in vehicles for several reasons. This component is always in operation, mapping everything around. It emits beams of light that bounce in an object and are received again by the vehicle. Next to the GPS positioning and the speed at which they advance, they create a three -dimensional map that takes advantage of thousands or millions of calculations per second. This has several implications that should be remembered. The use of this type of sensor allows a car to map with maximum exactly what it has around, something that they want to limit from the United States and China in the LUCK OF COLD WAR that both countries are freeing. In the United States they intend to Prohibit the sale of every car that uses Chinese software. In China, cars that want to use driving aid functions or Autonomous drivingwhich force the land to map, have to receive the approval of the government. A good that passes, evidently, to associate with a Chinese manufacturer. But, in addition, Lidar sensors are very expensive. The savings obtained in his commission to Hesai would have inclined the balance in favor of the Chinese company by Mercedes, they explain in Reuters. And it is that a vehicle can offer Semi -automated driving systems Without the use of these pieces but it is shown that, for the moment, The use of Lidar makes the difference. Although it may be more unknown in Europe, Hesai Group is a giant that is already present in 37% of vehicles that are assembled in the world, according to South China Morning Post. The company provides this type of giant sensors such as the Geely group (owner of Volvo or Polestar) and Li Auto, one of the great Chinese startups of recent years and employs more than 1,000 people, according to Electrek. But just as it happens to Chinese automotive themselves, Hesai is trying to open up to the rest of the world. With the local market already covered, they need to continue opening new trade agreements and that of Mercedes can be just the first, according to South China Morning Post. In the middle they point out that this agreement opens the door to multiply the current economic performance of the company by 14 times. Despite being present in almost four out of 10 vehicles that are sold worldwide (Only in February They already supplied pieces to 20 different brands and 120 models), the company gave brief benefits last year (14 million yuan, about 1.8 million euros in 2024) and He came out of losses of more than 241 million yuan (30.5 million euros) of the previous year. However, by 2025 they already expect net benefits of between 200 and 350 million yuan (between 25 and 44 million euros) achieved thanks to a scale production that supplies their products to about 15 million vehicles. That scale economy has allowed it Five years ago Each of them cost thousands of dollars. In view of a calculated expansion, the company, indicate in CNEVPOST Study to open its first floor to produce Lidar sensors outside China this year. Although it is not specified what places could be chosen, they do notice that they hope that the production of start in 2026.

Kukulcán’s show that the Maya created 900 years ago

by

Every year, around March 21, an old Mayan God returns to Earth. Specifically, Chichén Itzá. This complex of Mayan ruins It is one of the main pre -Hispanic archaeological sites in Yucatán and, among all constructions, ‘El Castillo’ takes the palm. It takes us fascinating Since the mid -nineteenth centurybut in addition to knowing him by that name, we can also refer to him as the temple of Kukulcán. And, like every Spring equinox For centuries, that divine snake has been about to come alive to descend through the staircase and inaugurate the spring station. Kukulcán. Although the mythological imaginary of the Maya was incorporated late, Kukulcán soon won a fundamental position in this pre -Hispanic culture. That is, if it were a minor deity, it would not have something as monumental as the pyramid that the Maya built in their honor in the twelfth century DC Thus, Kukulcán is the supreme god of the universe that not only represents wisdom, but also fertility and life. Photo by Daniel Schwen The castle is so fascinating that it is still reason for study todaybut centuries after its construction, there are two moments every year in which their stairs are a footpasted again by a God. The descent of the feathered snake. The structure has a very precise shape and orientation that respond to the advanced mathematical and architectural knowledge of the Maya. Kukulcán is also the God who represents fertility and life, something that can be associated with crops, and the visit of this God is a blessing for crops. The sowing of the Milpaspecifically. Thus, the Maya built their temple very precisely so that each spring equinox, which occurs between March 21 every year, the representation of the snake again descended through the staircase of the temple. This 2025 se esteem which will occur between March 20 and 23. A few hours before sunset, the large blocks of one of the sides project triangular shadows on the side of the staircase, forming a series of triangles that connect with the huge stone head of the snake, Kukulcán, located at the base of the pyramid. Beyond the show. Apart from those huge mathematical, astronomical and architectural knowledge of the Mayan civilization, the descent of the feathered snake marks the beginning of spring and, therefore, the renewal of life. He also symbolized the union between heaven, earth and underworld and supposed a blessing for crops. It lasts little, just about ten minutes and can also be seen during the autumn equinox, around September 22. In the end, it is the two periods that mark the beginning of the two agricultural cycles and it is Kukulcán who gives his blessing so that the crops are abundant. A party. Apart from symbolism and tradition, Kukulcán’s descent by the staircase of Chichén Itzá is a Tourist stop mandatory if we are in the region. This Archaeological site It is, by far, The most tourist point of the Yucatan Peninsula (and from Mexico), with tens of thousands of visitors every year, and the show of the feathered snake is another opportunity to take advantage of pre -Hispanic construction. Now, greenhouses and crop rotation allow us not to depend so much on Kukulcán’s good humor, but we have turned their two annual arrivals into a party that brings together thousands of visitors. It is a show not only because it is the construction of the pyramid, but because traditional Mayan shows and rituals are carried out with music and dance. Chance? That the Maya had great knowledge in mathematics and astronomy is somewhat indisputable, but there are positions that question that all this of Kukulcán’s descent was the result of the conscious design of the Maya. The reason that is used in the re-evaluation Of this thought is that yes, the phenomenon and the play of lights is important during the equinoxes, but the same effect can be seen clearly for several weeks. Rather, instead of marking with tremendous precision a few days of the year, the Maya would have darling Mark an agrarian cycle from mid -February to October. As much as it may be, and it had the meaning that we give now, the architectural value of the site and the architectural intention of representing that descent of the feathered snake is still unappealable. Kukulcán’s head | Photo by Frank Kovalchek But … it’s not unique. Now, although that of Chichén Itzá Castle is the most famous point in which to visualize these projections, it is not the only Mayan construction in which a similar phenomenon occurs. In it Temple of the Seven Dollsor temple of the sun, in both equinoxes we can see a solar rays show through the openings of the structure. Also in the Mayapán pyramidbut the big difference between the pyramid of this city and that of Chichen Itzá is that there is no huge snake head connecting with the earth and that, in addition, it is not as well preserved as ‘the castle.’ Centuries after his arrival, and although now he has less work, surely Kukulcán feels honored because his pyramid not only stands up, but for having turned his figure into the protagonist of a party. And that is why he continues to descend for one of the main constructions of the Mayan culture. In Xataka | The fines imposed by Mexico for getting on the pyramids of Teotihuacán or Chichén Itzá

Spain has moved the ‘Rodas Project’

by

This year it seems that it will be the year of nuclear fusion in Spain, because as soon as 2025 started they have managed to produce the First plasma in the smart reactor. This advance that placed the country at the forefront of nuclear fusion research, now will take a step further for consolidation. An answer. Spain has decided to focus its efforts on nuclear fusion and will present the Rodas Project. An initiative in which four research centers and five companies participate, which not only promotes the merger industry in the Spanish nation, but is also part of a global strategy in which more than 30 countries participate. A safe and sustainable source. Nuclear fusion has an almost inexhaustible availability of resources and presents great security, so it looks like a Energy solution. However, one of the challenges is in the manufacture of large and complex components that can withstand high temperatures and radiation. The Rodas project. As They explained a few months ago The research head, the Center for Energy, Environmental and Technological Research (CIEMAT), the initiative will last four years. As The economist advancedthe main project challenge is to create materials that support extreme temperatures and high levels of radiation, while optimizing production processes to make them more efficient and sustainable. They also hope to reduce the production times of components of eight to two weeks and reduce the waste of material by 80%. The consortium. The project It is led For the CIEMAT and has the participation of the University of Granada, the Idonial Foundation and the Hiperbaric, Leading, Innomaq21, Novadep Ndt Systems and Rovalma companies. Each has contributed key elements of their specialization. First, hyperbaric He has worked In the development of a new generation of presses and hot isostatic pressed ovens, essential to improve the mechanical properties of materials. On the other hand, together Leading and Innomaq21 They have focused in the optimization of additive manufacturing processes and in the development of high precision assembly techniques. Third, Novadep Ndt Systems has contributed Your experience in non -destructive inspection systems to guarantee the quality of the components. For his part, Rovalma has specialized in the creation of advanced alloys with optimized properties to withstand extreme conditions. Finally, so much The University of Granada and The Idonial Foundation He has contributed his research modeling and behavior simulation in merger conditions. The closure of nuclear centrals. Between 2027 and 2035, Spain has on its agenda close nuclear plantsthis procedure that is in full controversy. In contrast, the country will invest in fusion because nuclear fission – the technology used in current plants – generates hazardous radioactive waste creating a chain reaction. In addition, in the future, a single fusion center could replace the seven fission reactors currently operating in Spain, reducing the risk of radiation. Forecasts This type of project is has estimated which would take at least 50 years to develop, but the first commercial reactors may be earlier than plan Granada neutron accelerator and The Iter experimental reactor in France.

Experts begin to think that the problem is not mobile phones, but the algorithm

by

He wrote Hermes Trismegisto in his Kybalioneverything in creation has its rhythm and that rhythm, if we follow it, always takes us back to the beginning. It takes us to the world as will and representation, in the way Zaratrusta spoke, to the recurrence theorem of Poincaré … and, of course, to the discussion of whether the technology is leaving us fried by the brain. Or, rather, what, how and why it is affecting our cognitive ability. Because the fact that something is changing nobody discusses it. And how to discuss it? Of course something It is changing. And not only functionally, the changes are structural and all levels. The simple presence of screens It has substantially modified our somatosensory cortex; That is, they have changed the way we touch the world. There is nothing. But the situation goes further: how Manuel Sebastián explained years agoresearcher at the Cerebral Cartography Unit of the Complutense University, “we know that the text that includes links (hypertext) seems to remember worse in general, which is totally logical because they constitute distractors and the role of attention is critical in memory.” We knew that, but we didn’t know what it meant. “The fact that information is processed differently is not necessarily bad,” Sebastián told us. In the background, our brain Life is reorganizing And historically, that has been a good news. The question is, therefore, if it will continue to be in the future. And there are many experts who believe no. Data are not lacking. As John Burn-Murnoch explained in the Financial Timesalthough in recent years we have lent a lot of interest in the impact of pandemic on the cognitive and emotional development of young people, there are more and more experts who think we are not seeing it in perspective. Both the scores of most standardized tests of the world (as the PISA report) and Some specialized surveysThey point out that the problem began to appear in the mid -2010. And that problem It has many faces: From the difficulty to concentrate on the problems to learn new things. It is a bit complicated. Because, the truth is that, if we look at things like the time of use of screens and cognitive or emotional problems, we discover that There is nothing problematic. The traditional explanation has been that the important thing is not that we use new technologies, the important thing is what we do with them. And that’s where the algorithm enters. Because, As Burn-Murdoch saysthere is a change perhaps more fundamental than mobiles and networks: “the change in our relationship with information.” We have gone from web pages limited to infinite and constantly updated feeds, with a constant notifications bombardment. We no longer spend so long navigating the web or interacting with acquaintances, but we find a content torrent. This represents a transition from self -directed behavior to passive consumption and the constant alternation of context. And that’s where the problems may be. Unfortunately, There is still little research on this And, to the extent that everyone has launched this type of technologies and algorithms, we find a very difficult area to investigate. The good news is that, little by little, we are clearing the issue. The bad is that there is still much to know, even, the impact of all this. And, despite everything, as we usually check Every time an extensive study is published On our relationship with technology, there are no great alarm signs. Anyway, it seems that the plasticity of the human brain Find the way of “returning home”to overcome possible obstacles and catch up. Hopefully let’s know how we can eliminate those obstacles.

The audiences, in unpredictable terrain between the bad Broncano streak and the increasingly patent recovery of TV5

by

‘La Revuelta’ It seems to have worked as a revulsive for the stagnation situation that the traditional television audiences liveEl Hormiguero‘. Nothing that was released in that strip seemed to be able to compete, and no format that Tele5 experienced after the fall of ‘Save Me’ planted face. From the fall of last year, however, and with its audiences matching and surpassing those of motorcycles, Broncano seems to have launched a poisonous dart, a doubt: there is nothing sure in the figures of linear television spectators. Broncano collapse. A little less than a month ago We talked about how, with six months of the premiere of ‘La Revuelta’, the competition with ‘El Hormiguero’ had not yet thrown clear data. In the last quarter of 2025, Broncano came out victorious, however little, in the strip of strict coincidence and also in the number of spectators. However, both the Champions and, especially, the unexpected success of ‘The island of temptations’ has affected Broncano’s figures, which had a historical minimum last March 12 And, in general, its lowest figures since it premiered in autumn. The solution, this Thursday. Taking advantage of the fact that this Thursday will be issued number 100 of ‘La Revuelta’, TVE will experiment changing the emission timeand delaying it until 22.35 hours. Like so many other times, Broncano sees his time changed because of football, since TVE will give the match between Spain and the Netherlands before. The seventh gala of ‘Celebrity sewing teachers’, which It is not having very good audiences eithera week is postponed. It is unlikely that TVE is looking for a schedule change for ‘La Revuelta’, since it cannot be allowed, as Tele5, to base its entire grill on a single product. But at the moment it can be an experiment to verify how it is given to escape from the motorcycle sponator. Meanwhile, Telecinco triumphs. Although the Mediaset channel is still in total audiences below Antena 3 and the1 (it will be necessary to see if it recovers second place with the spectacular audiences of ‘The island of temptations’ and ‘survivors’ of March), its climb thanks to the Montoya phenomenon is remarkable not only for the damage it is doing to Broncano, but by the improvement itself for the global computation of the channel. And it is not the only strip that improves its data, but that mornings and afternoons have also experienced remarkable increases. Realities Explosives Montoya became Thanks to the power of memes In a global phenomenon, but what Telecinco perhaps did not expect was that it helped to give a tremendous push so much to the final stretch of ‘The island of temptations’ (a spectacular 26.9% quota came to have in its tenth week on Monday, leading every week and with an average of 19.1%). But the phenomenon continues: in its second week, ‘survivors’ already averaged 20.6% of Share in its main section, and exceeds 20% in three of its first editions. Figures completely from another era, almost pre-streaming. Not everything is the islands. And not just that. Last week, Ana Rosa showed that His return to the morning It had been a good idea because it is not only planting face (without destroying, but enduring the envy very dignity) to Arús, but since he left the afternoons, ‘late’ is strengthening his presence. Last Tuesday 11, both Ana Rosa (15.8%) and ‘afternoon’ (10,1) made respective records of Share In his trajectories, and also ‘Jorge’s diary’ (10) strengthened his space, since he has a good run of double -digit audiences, and on Tuesday he made his best fact since its premiere, demonstrating that the change to the second half of the afternoon has sat very well.

Someone used AI to overcome an interview on Amazon. His success has made Google see his candidates face to face

by

There is a thin line Between genius and deception. With the arrival of artificial intelligence, this line is fade even more and the scope of work interviews are a good example of this. A student exceeded a technical interview of Amazon helped with AI and his success has had consequences: someone gave him away to his university, he has created a company so that others use AI in their work interviews and Google will stop doing their work interviews remotely in the face of increased the use of AI by the candidates. The debate on whether the use of AI has been opened in a job interview It is cheating Or it is to use the tools at your fingertips to find a solution to the problem. Entrepreneur or cheater? According to published CNBCChungin “Roy” Lee is a 21 -year -old computer student at Columbia University who got some work interviews in large technological ones such as Amazon, Meta or Tiktok. During the remote technical interview with Amazon, the student used an AI tool that he had created with which he could easily answer the programming questions and tests asked for the Amazon recruiter. “Today, everyone program with the help of AI,” said the young student to CNBC. Technical tests are an essential requirement to access engineering positions in these large companies so the young man had no choice but to prepare conscientiously as can be checked on his profile of the website of the website Leetcode training. Such and As you collect Gizmodothat training was one of the hardest tasks that Lee faced. “It was one of the most unhappy experiences I’ve had programming. I felt that I had to do it. It was something I needed for a job in a large technological company, and there was so much to learn, so much to memorize, and so many random problems that I could wait for me to ask me. He made me hate the programming.” According to the student, the problems that arise in the interviews are very unlikely and more a “theater” approaches in which the interviewee pretends that he has never seen that problem, when in reality he has already studied and memorized his solution. “They are not representative of what you do as a programmer at work,” said the young man. To lighten this “technical procedure” the student used a tool he had developed to successfully overcome his interview with Amazon. The test result was a success and ended up receiving a job offer in the company, although the young man rejected it since the interview was only a way to test his tool. A video with the recorded test that hung on your YouTube account (now not available) and on the tool website are proof of this. Chivatazo and university file Days after his technical interview, Lee received a notification from the University of Columbia informing him of a disciplinary hearing that the teaching entity had opened to the second year student, as you can read in the letter that Roy Lee has published In his X profile. As published by Gizmodo, the University showed its rejection of the use of AI tools as “support” to these technical tests, which it considered as a trap. “Amazon has a long tradition of collaboration with Columbia Engineering … and we are deeply worried that situations like this occur. We trust Columbia will take the appropriate measures regarding this student and we hope to continue with this long collaboration,” says the university in its writing. The young man, far from being concerned about the measures undertaken by the entity, offers the tool so that other students and candidates can use it in their interviews. Face to face in technology Due to the increasingly frequent use of these AI tools during interviews, great technological ones are thinking about again doing these technical interviews in person. Such and As I pointed out Cnbc en One of the latest meetings of L sundar interviews in person. This request contrasts with the fact that, only a few months before, the own Google CEO admit That, thanks to AI, around 25% of the Google code was generated by artificial intelligence. The use of AI is increasingly present in selection processes. From the Use of candidate monitoring algorithms (ATS for the acronym in English of Applicant Tracking Systems), that They automatically select the curriculum of the most appropriate candidates, to methods of training for candidates Based on chatgpt or, like Roy Lee, the Use of AI during interviews remotely The use of AI tools in selection processes, especially by candidates, has opened A debate on social networks On whether this is a lack of ethics, or is as valid as any other tool with which you work daily. In this debate, there are those who see right to use these tools during the interview whenever it is done transparently, since it shows that the candidate has resources To find the solution to a problem. “I remember that once, more than a decade ago, I said in an interview: ‘I do not know that specific command, but there is Google for what we do not know.’ assures a user which raises an equivalence between the use of AI and the search engine. Others, on the other hand, ensure that the objective of these tests is precisely to check the programming skills. If it is altered using AI, loses its reason for being.

AI agents are promising. But as in Tesla’s FSD, you better not take your hands from the steering wheel

by

AI agents are one of the great trends of AI This year. There are many expectations put in these models of AI capable of completing a task from beginning to end for us and almost if our intervention. And yet, one thing seems clear: for the moment it will be better “not to remove your hands from the steering wheel” and watch every step they take to prevent the AI ​​agent from being starring. Autonomy and trust. The Tesla driving assistance system –badly called Total autonomous driving (FSD For its acronym in English) – it requires that the user trust him to get carried away and that the car takes us from a point of origin to a destination without human intervention. IA agents propose a similar idea, to complete a task from beginning to end autonomously, but for this we must trust that they are able to do so. decision making. The agents will require huge data amounts and access to updated sources of information to analyze such data and then make decisions. In the past we have seen how AI models are especially good at the time of Summarize concrete information Or to draw conclusions from limited data, which is very useful for that decision making. Learn from mistakes. Tesla cars receive FSD frequent updates to improve their behavior. These updates are nourished by the data collected by the company when your FSD system is used, what allows you to polish the service. Something similar is expected to happen with AI agents, which will improve – especially at the beginning – when they are updated and “learn from their mistakes” when processing user requests. AI and companies agents. These types of solutions will be especially striking in companies that can thus automate processes that previously required total or partial human intervention. And precisely that is why this type of integration must be done in a very controlled way, because let’s admit it: we cannot trust 100% of the current AI models. Tesla knows that FSD is imperfect. It happens of course in the FSD of Tesla, which since its inception has been involved in various accidents, some of them with fatalities. One of the most recent was notified in October 2024: the low visibility made a TESLA with FSD activated a few months ago will run a pedestrian. Tesla has been criticized on numerous occasions of misleading advertising and of save the maximum on radars and sensors To achieve greater profit margin. AI agents can be equally dangerous if they are used incorrectly and “without having their hands in the steering wheel.” Users and companies that begin to use them must keep these risks very present. The hands behind the wheel, please. The conclusion was already clear in the Tesla FSD system, but also in the case of agents. They have barely done only appear on the market shyly, but everything indicates that this is one of the great trends of AI by 2025. And the problem is that the models of AI are imperfect and therefore can make mistakes, but it is that in the agents of that error it will increase. That they tell Air Canada, who had to return money to a passenger which obtained an erroneous response from the airline chatbot. Or to Chevrolet, whose chatbot was “deceived” by a user who achieved Buy one of your cars for a dollar. Domino effect. The accumulation of errors in sequential tasks is a fundamental problem in current AI models. We could say that it is something like the domino effect or the compound error: an error in an initial action distorts all subsequent decisions, generating results increasingly far from what expected. Imagine that in applications such as finance, medicine or logistics: consequences could be terrible. Solution: Constant supervision. To avoid this problem there are several proposed solutions. One of them is the establishment of check points. Thus, at the end of each subtarte the system-and ideally, a human user, what is called Human-In-The-Loop (Hitl)-should verify that everything is going well. It is also possible to minimize the risk using redundant systems – for example, using different models of AI so that the AI ​​agent uses them separately – or taking advantage of the information of the standard limits: if an intermediate fact thrown by an AI agent is too diverted from what is expected, we should rebound that process. And for the moment, spent (very) bounded. We are in a preliminary phase, and AI agents are “learning to drive alone”, so to speak. And the best way they learn is to go step by step and always starting with relatively simple and very limited scenarios. Thus, the ideal is to try to apply them to very specific cases and with a limited and known casuistry, so that their answers are as precise.

The chip war between the US and China is already leaving collateral damage. Although in South Korea

by

For the South Korean government Your semiconductor industry has a strategic role, like those of OLED panel production either Battery manufacturing. These three sectors have A very deep impact on its economyso it is understandable that the administration does everything in its hand to reinforce its position in the global market and increase its competitiveness. In mid -December 2023 Yoon Suk Yeol, the former president of this Asian country, traveled to the Netherlands with the purpose of consolidating an alliance with ASML in matters of integrated circuits, among other priority objectives. During the last months South Korea He has “faced” the US To protect the business of its main semiconductor manufacturers in China, among which are Samsung and SK Hynix. But his short -term perspective is discouraging. Sales of semiconductors to China have fallen in February 31.8% The Chinese market is essential for South Korea. It is at least if we stick to the integrated circuit industry. At the end of 2024 the country led by Xi Jinping represented approximately two fifths of all southern Korea technology exports, but the chips flow is plummeting. According to the Ministry of Commerce, Industry and Energy of this last nation in January 2025 the sale of chips It contracted 22.5% compared to the same month of the previous year. 2025 is going to be a bad year for the semiconductor industry due to the cooling of global demand and the impact of tariffs And in February the fall has been even more steep: 31.8% compared to February 2024. This trend supports the omens that predict for months that 2025 will be a bad year for the semiconductor industry due to the cooling of global demand and to the impact that tariffs presumably they are already having in the integrated circuit industry. In any case, to South Korea this incipient crisis seems to be affecting more than other countries that also live largely from chips, such as Taiwan. Samsung and SK Hynix lead the memory chips market, and much of their income comes from precisely these semiconductors. The US sanctions prevent them from selling their most advanced chips to their Chinese clients, which, precisely, are those that usually live with the GPUs for artificial intelligence (AI). China has responded by dedicating more resources to the development of Your own memory technologieswhat is causing A prices decrease which is clearly affecting the Samsung and SK Hynix business. Despite all the consultant Gartner has predicted that The AI ​​will pull the semiconductor industry For 2025, leaving the door ajar to the possibility that finally this year is not as bad for chips manufacturers as the first figures point.

An island in Japan has revolutionized its vehicles. They have turned cow droppings into hydrogen fuel

by

If we talk about hydrogen and mobility, we would possibly have to Add to Japan In the equation. Few companies have tried to make it a real alternative to the electric car like the Japanese Toyota, although it is true that in recent times the idea was Much more than in doubt. An island has shown that technology is still there. Of course, with the invaluable help of tons of cows excrement. The solution in Hokkaido. On the island of HokkaidoJapan, a key region for country production of the countryan innovative project seeks to convert the Hydrogen cow manurethat clean fuel with the potential of feed vehicles, homes and agricultural machinery. With More than one million cows Currently generating 20 million tons of manure per year, this source of waste represents an environmental problem due to its methane emissions and its impact on the Water quality. He Shikaoi Hydrogen Farmlaunched in 2015 by the Ministry of Environment of Japan, addresses this challenge by transforming waste into a sustainable energy resource. As? The manure and urine of cows are Farm collected local and sent to an anaerobic digester, where bacteria break down organic matter to produce biogas and liquid fertilizer. Then, biogas is purified in methane, which later becomes, hydrogen. Sustainable mobility. The plant has a production capacity of 70 cubic meters of hydrogenenough to supply up to 28 vehicles with hydrogen cells per day. In addition to cars, the fuel is currently used In tractors and forklift of the island, whose electrification with batteries is more complex. It is also stored in Canisters that are transported to provide energy to a sturgence fish and Obihiro Zoo. Challenges Several, of course. The main one is logistics, since it must be stored in high pressure tanks, which does so susceptible to leaks and degradation of materials, in addition to requiring specialized infrastructure for transport and distribution. Your acryogenic lmacement at -253 ° C is energetically expensive, which hinders its scalability.

In fact and as we said at the beginning, Japan leads the hydrogen industryalthough the electric cars still They are more profitable than those driven by this gas. Hydrogen from waste. The truth is that the concept of producing hydrogen from waste is not limited to Japan. Other initiatives in the world explore alternative sources such as Pork manurepoultry and even Coconut peels. For example, in Thailand Toyota investigates hydrogen production From chicken excrement. In the United States the University of Illinois developed A METHOD TO MANUFACTURE HYDROGEN With manure, sugarcane residues and corn cobs, significantly reducing the energy consumption of the process. And in Fukuoka, Japan, a wastewater treatment plant produces hydrogen From human wastesupplying a fleet of garbage trucks without emission. All initiatives show that bioenergy from waste can play a key role in the global energy transition. However, the lack of infrastructure and high costs remain barriers for large -scale expansion. Uncertain future. He Project in Shikaoi It is an innovative example of circular economy, where waste becomes energy, reducing emissions and promoting sustainability. However, the viability of hydrogen as an alternative to fossil fuels will depend on technological advances that reduce their cost of production, storage and distribution. Although manure and cow droppings will hardly be the main source of hydrogen in the future, especially worldwide, initiatives such as these can lay the foundations for a new energy industry based on waste recycling, with potential applications in transport, agriculture and clean energy generation globally.
