It grows and is able to ‘hack’ the brain

by

The works Cyberpunk They are continuously human improved thanks to bioimplants. A decade ago It seemed somewhat distantbut recent years we have Taken leaps In that machine-corebro connection with Implants such as Neuralink. Make our brain feel as part of the body that are not an achievement, and precisely that is what Massachusetts researchers are experiencing with a very clear objective: ‘Hack’ our brain with dental implants that feel really teeth. Bioengineering. We carry more than a decade investigating how to make the teeth grow again. Different centers have been all this time experimenting with stem cells with the aim of filling that cavity resulting from the fall of a tooth with living fabric that restores the fallen piece. The reason is that it is always preferable to have a piece with real dental material because it offers something that an implant, at least for the moment, is unable to give: tooth-cerebro connection. Intelligent implant. Feeling a natural part of the body is the Great objective of bioengineering for both the teeth and limbs that are missing and in which We have placed a prosthesis. The Last advances They arrive from researchers at the Faculty of Dental Medicine and the Faculty of Medicine of the University of Tufts. Have developed what describe As an “intelligent implant”, an artificial tooth such as any common implant, but with an outer layer that is in what is that “bio” part of “engineering.” It is a coating that contains stem cells and a specific protein that allows those cells to mature to develop nervous tissue. Hacking The brain. Jake Jinkun Chen is a professor of periodontics at the Faculty of Dental Medicine of the Center and comments that “the natural teeth connect to the jaw through a soft tissue rich in nerves. It is what helps perceive both pressure and texture and works as a guide in chewing and speech.” A point that “implants do not have that sensory feedback” because they are ceramic crowns on titanium post -shaped postanium posts that anchor the jaw and, although they are useful, they feel like a strange object in our mouth. Advances. To place one of these implants is also very invasive and, although it is a “chewed” process by surgeons due to the amount of operations that are carried out, there is always the risk of causing local or worse trauma: damage some nerve. Although everything comes out perfectly, as we say, we will not feel the piece as we do with a real tooth. The implant that they are developing in TUFTS, however, does not require that surgical procedure. The new piece is, initially, smaller than the tooth that replaces, and that layer of rubber nanofibers that expands is the one that fill the hole by joining the soft tissue of the jaw, not in the bone. And, little by little, he continues to reconnect with the nerves while the healing progresses, restoring communication between the mouth and the brain. The goal is to restore nerve connections between the lost piece and the brain to feel the tooth again Tests (keep taking care of your teeth). Everything seems promising and feeling the temperature and texture of a food again in a tooth that is not the biological sounds great, but as those responsible confirm, it is something that is in an early stage of development. That implies that it goes long and, for the moment, they have been successfully tested in rodents. They comment that the results point to a correct biocompatibility, functioning as a normal tooth only six weeks after surgery, and are currently analyzing the brain activity of animals to evaluate the sensory information they receive from that new tooth. Next steps? Test in other animals and, subsequently, climb the clinical trials with humans. Beyond mouth. “This new implant, and the minimally invasive technique should help reconnect the nerves, allowing the implant to ‘speak’ with the brain as a real tooth would do,” says Chen, and the big question is: if it works with teeth, Could it work with other parts of the body? TUFTS researchers have not entered into detail, but they have commented that, if everything goes well, this technology could “Transform other types of implants bone, such as those used in hip replacements or in fracture repair ”.

Prepare for a summer of delays and historical cancellations

by

Yes Summer holidays They were going to be very complicated for many Spaniards, or directly null because they find them impossible to materialize themfor which their bags can be made a perfect storm in the form of prediction. Europe warns: it is very possible that the typical summer air chaos is a thorough with what is to come. The perfect storm. Yes, the European Commission has warned that this summer the record of Delays and aerial cancellations due to one Critical combination of factors. Namely: the unprecedented demand after pandemic, the chronic shortage of air controllers, labor strikes and the impacts of climate change. The European air traffic control system operates to the limitmanaging near 37,000 daily flights In its most intense days, the maximum you can assume with the current template. Although traffic has increased by 5% compared to the same 2024 period, delays have also increased in equal proportion, predicting a repetition of chaos that marked the previous summer. The most affected areas: Key tourist destinations such as France, Germany, Greece and Spain, where “high” delays are anticipated due to the inability of the control centers to absorb the planned traffic flow. Strikes, obsolete systems and blackouts. One of the most critical foci is France, where The recent strikes of air controllers due to lack of personnel and aged equipment caused the 4,000 flight interruption In just two days. Europe Millionaire losses due to the operational collapse in Charles de Gaulle. The European Transportation Commissioner, Apostolos Tzitzikostas, has also indicated the reduction of airspace available in the continent as a direct consequence of the war in Ukrainewhich further overloads open routes. In this context, the call to the EU transport ministers It has been clear: States must ensure that aerial controllers comply with the promised capacity and are present where they are most needed. Climate change. To the technical and labor difficulties an increasing and unpredictable factor is added: Climate change. Forest fires have already forced to close temporarily Marseille airportwhile in Greece the high temperatures They forced the closure of tourist monuments such as acropolis. Community authorities fear that this type of extreme phenomena (Heat waves, storms, fires) become more frequent and dangerous for aviation. With airports “more busy than ever”, such as The Tzitzikostas Commissioner warnedthe risk of operating chaos is higher than ever. Slow formation. I pointed The Financial Times That another bottlenecks is structural: the formation of air controllers in Europe requires up to five yearswhich prevents an agile response to the growing demand. The commission collaborates with air security agencies to review these regulations, but immediate results are not expected. Meanwhile, associations such as IATA They accuse the managers of the European system of systematically breaking the capacity of capacity without consequences or sanctions, qualifying the situation of “unacceptable” and accusing a gap between the plans and the reality that “approaches the field of fantasy.” Fragmented sky. Air operators also insist that part of the problem It is political: The EU has not completed the initiative of the Unique European skywhich would allow to draw more direct routes between countries instead of the current fragmented system that forces aircraft to deviate through multiple intermediate points. This lack of coordination Increase costs operational, fuel consumption and flight times. As illustrated in the Times A high manager of a large tourism agency: “A London flight to Cyprus is not in a straight line, it crosses several unnecessary air points because Brussels has been exasperatingly slow.” The price to pay. If you want also, what is at stake is not only operational efficiency, but Trust of millions of passengers and The prestige of one of the dense and complex air spaces on the planet. Airlines already alert customer reaction: Anxiety, preventive cancellations and fear of summer collapse. With an air network to Edge of saturationwithout sufficient personnel reservations and with growing threats due to both natural and geopolitical causes, Europe faces the urgent challenge of reorganizing its air control system, modernizing its infrastructure and eliminating obstacles that prevent unified management. Otherwise, this summer aims to be, not only the worst in terms of delays and cancellations, but also the definitive notice that the sky of the old continent needs a revolution at several levels.

You cannot climb to the Madrid subway with an electric scooter. In China’s, robots are already a passenger

by

In October 2023, An incident with the battery of an electric scooter It caused the closure of a subway line in the capital of Spain for three hours. That led the authorities to prohibit The entrance of these devices to public transport Until 2027. In China, there are other battery devices that are already driving at ease by the subway network: robots. Which until not long ago was science fiction material, Today is a reality. The world is pushing the development of robots and, while until recently the demonstrations by companies such as Boston Dynamics They were limited to bailongos robots focused on professional environmentstoday what come to us are machines created for all types of ends. Boxing robots, football robotshumanoid robots that We can buy for what a car costs and even Robot dogs for blind people. And something that everyone has in common is that they are already being tested, one way or another, In China. The latter is an army of robots that already go from side to side for the Shenzhen subwaytaking trains and rising in elevators. And it has all the meaning of the world. Robots assault the subway A few days ago, 41 company robots VX Logistics They began to circulate through different Shenzhen Metro lines. They have a processor that allows artificial intelligence tasks, have Lidar sensors With “viewing” panoramic and that AI work allows them to make decisions in real time to make the best decision when it comes to their destination. The goal of this robot squad is to bring supplies to stores 7-Eleven located inside the stations and, for this, they not only take the subway: they are also capable of going up and down in a totally autonomous way and without supervision by the elevators of the stations. With considerable size and an aesthetic that resembles that of Robots-Camareros They are appearing in some Spanish restaurants, these machines They can load up to 130 kilos of weight. At the moment, it is a pilot program to see how they manage to distribute among the more than 100 stores 7-eleven distributed by the Shenzhen network, with nine million of daily customers, but the goal is to expand their scope. There are elements to take into account in all this. VX Logistics is part of Vanke, a Chinese real estate giant who is also co -owner of the Shenzhen Metro. But, beyond the marketing that has “free” more than 40 autonomous robots for the subway, as we read in SCMP It is something focused on solving a classic network problem: the refueling of stores. Li Yanyan is a manager of one of these stores and, as he explains to the local medium SZ News, “the distributors had to park on the surface, download the merchandise and take it manually to the inside. Now, with the robots, it will be easier and more comfortable.” They don’t say What will happen to those deliverymenif they will be in charge of providing the goods to the robots or if their function will be reduced more. What is known is that, as the company itself has communicated, the robots will be perfected based on their real -world performance. Now, apparently, These robots only operate in valley hoursin which less people are using the network. And less bad that they only operate in valley hours, because agile, what is said agile, are not. What has caused is that the first days of robots work, travelers are They will look or take pictures. The robots were already prepared for this, with a screen that shows a friendly “face” when it crosses someone. We will see how they develop and how long it will take to see similar robots in other stations, but what is clear is that China is pushing strong in the robotics segment For the “day to day” and Shenzhen is one of the lungs of his industry, with approximately 1,000 robotics companies only in that city, 18 of them Focused to humanoid robotics.

It comes from the Andalusian mountain and burns in French thermal

by

While Europe profile new sanctions Against Russia in the energy sector, the clock runs to fill the reserves for winter. In this context, France has decided to look south to supply its thermal plants and reduce its gas dependence: Andalusian biomass is placed in the center of the solution. Short. From the port of Seville a new export operation of forest biomass has come out to an electricity generation plant in the French region of Provence and Costa Azul. As reported by the Junta de Andalucía through a press release4,200 tons of biomass have been loaded, from jungle treatments made in Andalusian mountains and managed by the Novalis company. This operation is part of a public-private collaboration model that seeks to value the forest resources of Andalusia and position biomass as an exportable energy alternative. A paradigm shift. This type of exports shows a deep transformation in territory management: what was previously a residue or a fire risk, today becomes a clean energy resource with international demand. Andalusian woody biomass not only generates renewable energy, but does it with a neutral fingerprint in carbon, contributing to the decarbonization objectives of the European Union. In addition, active jungle improves the structure of forests and reduces plant load, which helps prevent forest fires. “For years conservation was confused with inaction and that has led to the abandonment of many mountains,” has pointed out in Europa Press The general director of Forestry Policy and Biodiversity, Juan Ramón Pérez Valenzuela. The process. The model is based on the tender for forest exploits on public land, especially in areas of high ecological value and risk of depopulation. Cleaning tasks, clareos and jungle treatments are carried out by specialized companies. Once classified and shipyard, biomass is exported through logistics infrastructure to energy facilities in France, Italy, Denmark and Sweden. Since the operation started in 2019, the port of Seville You have seen come out More than 400,000 tons of biomass: wood, cork and even olive bone that now serve to generate clean energy in Europe. Only the Sevillana Novalis company has moved more than 100,000 tons. If the exports also carried out from Huelva, Puerto Real or Almería are added, the total already exceeds 640,000 tons to countries of the north and east of the continent. Now there is no bottleneck. Spain has been seen as a Cul-de-Sac energetic: With limited infrastructures and with hardly any interconnections with central Europe. But when he is interestedas this operation demonstrates from Seville, it can be removed to the sea and what was only gas in gas pipelines, now they are mountains converted into heat. It is not the only case, since companies like Burpellet, in the small bourgeois town of Doña Santos, They consolidate this idea. With a production of up to 150,000 tons per year, its plant demonstrates that biomass can be a viable industrial solution for rural areas, without losing its local scale. The mountain as the energy of the future. The Junta de Andalucía does not hide your bet. The operation in the port of Seville is a sample of the deployment of the Andalusian Forest Plan Horizon 2030, which mobilizes 300 million euros per year to promote the multifunctional management of the mountain. And it will also be the basis for a future mountain law that consolidates the productive and sustainable use of the territory. At a time when Europe fears the cold of winter and heat of energy crises, Andalusia sends more than splinters: exports clean energy, active forest management and future for their peoples. The mountain, finally, is again the protagonist. Image | Port of Seville Xataka | Sea water to heat the streets: the idea of a German city to have more sustainable heating

Back to V8 or walk to the electric car. And that says everything about how the industry is

by

“The electric is the future” The words are from Koji Watanabe, head of HRC (Honda Racing Corporation), the division of the Japanese firm in charge of developing the technologies that their teams (and those that hire them) use in the competition. Yeah Formula 1 goes back To the V8 engines, they leave. That is what the Japanese wanted to make clear. Right now, the company does not have an official car inside the championship but supply its engines to Red Bull. In 2026, They will do the same with Aston Martin And they have not ruled out having more customers for the future. But his role in the historic competition can have an expiration date. It all depends on the direction of the sport. The FIA (International Automobile Federation) wants to back the path to the electrification that took formula 1 in 2014. Its bet: Back to Combustion Motors V8. Some teams are for the work but others like Audi or Honda (this as supplier) do not want to hear about the matter. And the dispute threatens to put the sport up. “We didn’t come for this” The first thing we have to know is what is the current situation. The 2026 season will be a year of changes, we will have new chassis in cars and new power units. These power units will finally be maintained as a hybridized turbo. Of course, the weight of the electrification will be greater and the fuel will have to be 100% sustainable from 2026. This regulation should be in force until 2030. The problem is that since the arrival of the V6 Turbo hybridized in 2014 Fans have been complaining that something has died with The end of the V8 and V10. In 2021, despite everything, the regulations of these engines froze to prevent that Honda’s exit will leave Red Bull behind. The background problem is that new engines are giving bad results in simulations. To the point that There is spoils slower than those of Formula 2. The reason is that electrification will become 45% of the total power that a car can deliver (it is currently in 20%) and it is even believed that in a circuit like Monza, the pilot would have to lift the foot at the end of line so as not to end the battery and run out of electrical power for much of what remains circuit. That is especially important next year, since the electric motor will go from delivering a maximum of 120 kW (163 hp) to 350 kW (475 hp). Run without power electric at the end of a line is to be sold for the rest of the return with a very slow car. The way of driving and understanding the car changes radically. “The engine changes completely when braking and curves to produce additional energy, directly feeding on the battery. Therefore, the engine assumes the task of a generator at specific times,” explains Hywel Thomas, responsible for the development of Mercedes engines to Auto Motor Und Sport. That is, at times, the car will act as a series hybrid. That is why some manufacturers have long been moving threads to return the sport to larger engines and reduce the electric weight. He came to talk about returning to the V10whose devastating sound is iconic. Finally, they are pressure to return to the V8. That movement has not liked Honda, who consider that “electrification is a fundamental element To move towards a sustainable future, “making it clear that they do not wait for them if this happens. And he didn’t like Audi either. The company of the four hoops will have a car next year on the grill but the Germans say that ” Hybrid power units It was a key factor “for the company to launch into the pool. They have stressed that “the new regulation was planned for 2026 and beyond”. Returning to V8 is a setback for brand investments just over two years seen. And his message was clear: the V8 “was not for what we came here.” A message that clashes frontally with a good part of the manufacturers. In Motorpasion They collected months ago Ferrari, Ford and Cadillac (Ford will supply Red Bull engines and Cadillac will have its own equipment) They already supported the idea of returning to the V10 engines. And, without committing, Mercedes launched the message in China that “we have an open mind. We are prepared for any engine.” Everything this mess tells us about the industry What is being played with the next big change of regulations is much further than simply, the engines that the cars will use in the competition. It is no accident that Honda and Audi, firms that in their street cars are betting on the electrificationoppose the return of large V8 engines, in the worst stage for them, V10. Nor is it accidental that firms such as Ferrari, Ford and Cadillac support this second scenario. Or that Mercedes does not see him with bad eyes. Already in 2023Christian Horner, Mandamás de Red Bull that recently has been firedhe said that “maybe we return to some V8 or V10 that are totally sustainable. It would be fantastic!” This supposed sustainability goes through the use of 100% synthetic fuels, an idea that would have to go hand in hand if you want to reduce the electrification volume. The key here is that F1 is still seen as a laboratory. The jump to hybridization with the V6 Turbo was designed for manufacturers to explode what they learned with the MGU-H in its street vehicles. However, this component is really expensive and has barely had development out of the competition. With this failure in mind, Ferrari, Ford and Cadillac press to return to the V8 engines. The Italian company aspires to Synthetic fuels are part of its essence in the future. And it also has in mind continue developing large engines combustion since they will allow you to continue selling … Read more

So he used his 3D printer to make them himself and save 20,000 euros

Supercars are the culmination of passion for motoring And the speed, But, although they are a minority, not all owners of one of these Engineering jewelry They are millionaires. With a little luck and the passing of the years, some supercarghini, Ferrari or Porsche de Segundo can be achieved (or third hand) for a price much more affordable of what cost new. The bad thing in those cases is that, although cars have lost some of their value, the pieces of replacement to repair them No, and they are still extremely expensive. Especially when the car It is no longer manufactured. Little money, but a lot of ingenuity That is precisely what happened to youtuber B is for builda fan of cars and extreme customizations, which It was proposed to restore An old Lamborghini Murciélago LP 640 who had bought for about $ 35,000. A bargain taking into account that this model has cost about $ 150,000. But such a reduced price It has its explanation. The car had several seriously damaged body elements and, among them, the right lighthouse. To avoid the huge extra cost of the pieces in the concessionaire, he sought the replacement for his bat on eBay. The search was a success, but the best price did not fall from 20,000 euros for a couple of new original lights. Touch the photo to see the original message and the state of Lamborghini when you bought it As the youtuber recognized In your videospend 10,000 euros for each optics From its supercar far exceeded its restoration budget, so, far from discouraging, it chose a much more affordable solution: manufacture them with A 3D printer. To do so, he had to digitize the focus using a scanner and improve the initial scan with 3D modeling hours to finish profileing all angles of a piece as complex as the lighthouse. One of the many challenges he faced was the digitalization and impression of the rings that hold the bulbs lenses. When the scanner laser was manufactured in aluminum, it was not able to detect correctly the details. On the other hand, since they had to resist the high temperatures that the lights reach, these elements had to print with a specific resin with high heat resistance. Interestingly, the simplest part was the outer glass of the focus. Given the shape of the morro of the bat and be located in a delayed position, it was enough to cut a piece of transparent metacrylate with the proper form and adapted perfectly to the soft fall of the morro of the bat. 20,000 euros difference. Original focus (left) and 3D printed focus (right). After hours of evidence, sanding, adjustment and some paint, the truth is that the result was a very well achieved piece.

How to create videos with artificial intelligence: 13 essential free tools

by

Let’s tell you the best programs to create free artificial intelligence videos So you can give life to your ideas. Although the quality of the videos is not yet up to the images, they promise to be the next great revolution of artificial intelligence. However, before this revolution arrives we will tell you the main current alternatives. Virtually all the services we are going to tell you are paying, although with free versions that allow you to try them as a demonstration. Almost all also offer a small monthly or daily chip recharge, so you can continue using them for free, although With limited resolutions and with water marks. We are going to start with an explanation on how to create the videos with these websites, and then we will tell you the list of services. And as we always say in Xataka Basics, if you think we have left some important service We invite you to say it in the comments section so that all readers can benefit from the knowledge of our xatakers. How these videos are created To create videos with artificial intelligence using any of the programs that we are going to propose, what you will need is to write a prompt or command in which you describe what you want it to appear in the video. Then, the AI of the service will generate it. Many of these solutions also allow Create videos from images. This means that you can contribute a photo or drawing that will serve as a starting point, and then the AI will generate what you ask from it. There are two other types of videos by AI You can find yourself. The first is the images based on images that are moving with an off voice, where you will be able to contribute a script with what you want to happen. And finally, you will also be able to create Videos with an avatar speakinga person explaining something with a voice generated by the saying what you write. These can be used for explanatory video types. In all cases You will need to create an account In the services that we are going to tell you, and then you will be given a series of free tokens that you will use to create videos. The amount of videos you can create depends on each service, but there are usually few. Hailuo We start with this emerging service, simply because It is the one that has given the best results in the tests done to compose the article. It is quite new but offers decent results, and you will have enough free daily credits and for several videos. You simply have to use a prompt describing what you want and ready, in a few minutes you will have a prepared video. Your free plan only supports 6 second and 768p videos of resolutionalthough these can be from a text or generated from an image. I see 2 Google is developing its own AI engine to create video, whose latest version is I see 3. Although this is limited to payment users, there is a way you can Test the previous versionI see 2 that is totally free through the Ai Studio portal. The quality of the videos is quite lower, and we have encountered numerous problems due to excess use. Come on, that if there are many people using it at the time you want to create a video, it will directly give you error and you will not be able to do it. Adobe Firefly The function of creating videos with artificial intelligence of Adobe Firefly It is payment. However, allows you to create two free videos of about 5 seconds, as a test form, although for this you will also need to create and identify with a user account. Although most options are limited to the payment option, when creating video you will be able to choose the resolution and the appearance ratio, in addition to the frames per second and the duration. You also have adjustments to choose the camera or movement. Capcut Capcut is a popular multi -tool in which you can make all kinds of creations with artificial intelligence. Among them, is the possibility of create a video from a text that acts as script. You describe what happens in the tool, and this creates it. This function is free, but it has a trick. Videos are not moving imagesbut a succession of static images created with ia that happen, and with a background voice that reads the script you have written. Basic and does not give what it promises, but at least they don’t ask too much. Runway One of the great tools for Create Artificial Intelligence Videowhere you just have to describe what you want with a prompt. First you will create the initial image, which you can modify as you want, and then you already generate the video from it. The negative part is that Your free version is very limited. When you register for free, you are given 125 credits of a single use, and when you finish it, it is over. Therefore, although the quality of the tool is good, its free mode is a temporary demo. Kling AI Another good somewhat more generous tool in its free plan, since it offers 166 credits per month that are recharged monthly. Then, in general the videos can cost about 20 credits for 5 seconds, something else depending on the additional configuration options. Unfortunately, the version to create video to video videos is disabled unless you are a payment user, although you can always use another AI to create an image and then use the creation of video to video, which is what can be used in free mode. Of course, a free 5 second video may take more than 3 hours to generate if you do not pay. Invideo This is a kind of chatgpt for video. Has a free mode … Read more

The big problem of green hydrogen is the dependence of fresh water. We have found the solution in the sewers

by

In the great darking puzzle, Green hydrogen points ways to become one of the most important pieces. Has become one of the Great bets of the European Union For the Energy transitionbut although renewable energies such as solar or wind are used to produce it, it has a big problem: Consume a huge amount of fresh water. Some researchers want to stop this problem using something we produce in industrial quantities. Sewage. The water problem. Talking about clean energy implies looking at some initial point of the process to realize that there is still an ecological footprint. Electric cars do not emit, but make their batteries yesFor example. Something similar happens with green hydrogen. Solar or wind energy is which is used to perform the electrolysis process With which hydrogen is generated to use as a source of energy, but as we said, a lot of water is consumed, a resource that is increasingly scarce For millions of people. That is why we are investigating alternative ways to generate green hydrogen without those huge amounts of fresh water. For example, using seawaterbut there is a type of fresh water that had not been considered for the process and that has now entered the equation. Trash Treasury in wastewater. These waters contain a series of pollutants that, according to logic, would make it difficult to Electrolysis process. They have nickel, platinum, chromium and other metals that, until now, had to be extracted from water in an expensive purification process before using that water in electrolysis. However, a team from the School of Sciences of the Australian Rmit has found a way to take advantage of these metals to accelerate the production of green hydrogen. In electrolysis, electrodes are a key component because it is the one that facilitates the reaction that separates water in its base components: hydrogen and oxygen. To do this, an anode is used (where water breaks down releasing oxygen and electrons) and a cathode (protons earn electrons and form hydrogen molecules). In the anode and cathode metals such as nickel, platinum or iride are used as those found in wastewater, and what they have done from the RMIT is … take advantage of them. The invention. To do this, the electrode is manufactured with an absorbent carbon surface that attracts those metals present in wastewater, as if it were a magnet. When they “catch them”, form catalysts that conduct electricity and start that task of dividing water into its components. Nasir Mahmood is one of the researchers and, as we read in Miragenewsexplains the reaction as follows: “The catalyst accelerates a chemical reaction without consumed in the process, allowing metals to interact with other elements present in wastewater and enhancing the necessary electrochemical reactions to divide water into oxygen and hydrogen. And, beyond the theory, the team devised a device that managed They expose in ACSa stability of 95%. This pilot device, connected to a small solar plate, is the one you can see in the image that opens this article. And the waters look at everything … except purified water. Potential. Now, it is not as easy as taking the wastewater and using it directly. The team Confirm which used wastewater that had been subjected to some treatment to eliminate solid waste, organic matter and other nutrients. Not metals, yes. The water used for the experiment comes from agricultural waste, which opens another door to the circular economy of the materials. HE esteem that more than 80% of wastewater return to the planet without any treatment (although other sources They point at 50%), but if we started using a part to produce green hydrogen, we would be reducing that percentage, giving a breath to areas with drought problems and allowing to inject energy into those areas without affecting their Drinking water deposits. In developing countries it would have great potential. An upcoming step is to try more types of wastewater, since not all have the same amount of metals in their composition, and as professor Nicky Eshtiaghi, another of the authors of the study, comments, the plan now is to look for partners to climb technology and find commercial applications.

The most bestial data centers on the planet, gathered in this graphic

by

The development of AI has promoted a New ‘Armamentistic’ career globally. It is not sought to dominate another territory, but to get the more computing power, the better. The main technology companies are deploying centers from Data around the world With a goal in mind: train the artificial intelligence. There are data centers that are authentic burged, and in this graph we can see the most powerful data clusters in the world with an outstanding protagonist: Elon Musk. Cluster. Before entering numbers, a nuance. When we talk about calculation power, we can talk about a computer cluster or a supercomputer. The latter is a system Extremely powerful which can be built with processors specially designed to reach extreme calculation powers or, most commonly common, from thousands of high performance servers. They are used for scientific simulations and tasks that require a huge calculation process, and its cost is brutal. On the other hand, We have the “affordable” version of a supercomputer: the computer cluster. It is a series of interconnected work stations that work in parallel solving problems. It is similar to a supercomputer, but the advantage is that It is a more flexible system Because, as you need more teams, you can expand the cluster. In addition, the components are more standard, which also allows the cost to be lower. But well, it is a concept that has blurred in recent years. The 100,000 club. That said, let’s go back to the graph elaborated by Visual Capitalist With the data of EPOCH AI. In it, we can see the most powerful clusters currently, but with some trap: they are both planned and operational. X, Elon Musk’s company, lit the XAI Colossus Memphis Phase 1 last year, a huge data center with 100,000 NVIDIA H100 GPU With the aim of training ‘Grok’, his AI model. It was something that He even surprised Jensen HuangCEO of Nvidia. It is a computing monster with an enormous calculation power, but the figure is expected to increase up to 200,000 GPU. We will see later the energy consequences of this. Following Musk’s company, we have Meta by stating that they have a cluster “greater than 100,000 GPU H100“For her model ‘calls 4’. Then there are those who maintain something else the mystery. For example, Microsoft with its cluster For Azure, Copilot and the OpenAi AI estimated they have 100,000 GPU between H100 and H200, Two worlds. Out of that 100,000 club we have Oracle With its 65,536 NVIDIA H200, another Musk company -you with the Cortex Phase 1 and its 50,000 GPU, and the United States Department of Energy with The Captainhe Most powerful supercomputer in the world. Officers or estimated, what is clear with this graph is that there is a country that has taken the calculation of AI seriously: United States. They are the ones that seem to push stronger with their data centers in the United States (of the 10 clusters, the first nine are in the US and the last in China) and are not only building inside their borders: Also outside. An example is the finish plan for Build data centers in Spain or the one who has practically Manhattan’s size. European expansion. In the graph, we can see two European clusters. On the one hand, The Jupiter from the Jülich Supercomputing Center in Germany with its confirmed GPUs. On the other hand, the Nexgen In Norway, with about 16,300 GPUs. Europe has undertaken several financing initiatives with the objective of Promote your competitiveness Thanks to programs such as Genai4eu and its budget of 700 million euros between 2024 and 2026. The objective is to build large data centers and, for the call of 2025, 76 proposals were presented in 16 different countries. Now, that development of the European AI must be aligned with Ai actthe agreement in force since February of this 2025 that ensures transparency and an ethical AI. Number vs. efficiency in China. Who has put the batteries in AI, beyond US companies, is China. Following one Road map very different from the westernChina is focusing on having (supposedly) less GPU working, operating with greater efficiency, much lower costs than those of American companies and with equivalent results. Deepseek or the most recent Kimi They are two samples of it. Nvidia rubs her hands. And of all this battle for AI, there is a clear winner: Nvidia. As much as it may be, and beyond who has more or less GPU to do the job, the clear winner is Nvidia. In China it is not so clear due to the commercial veto, but the main world data centers use Nvidia’s architecture with their GRAPHS H100 Y H200. And that if we talk about “normal” cards for AI, since they have the B200 with four times the performance of H100. In fact, the company seems so focused on that AI career that would have neglected what led by AMD for years: Your players cards. Those are servers of Lenovo data centers. Companies seek to reduce the footprint reusing hot water after dissipation to, for example, fill pools or showers. Image | Xataka The planet, not so much. And the consequence of that expansion of the AI is that data centers not only need huge energy amounts To function, also water to dissipate the heat of the equipment. There is an important absent in the graph, Google, which also operates its data centers for AI and that, together with others as goal or Microsoftneeds nuclear centrals to feed its facilities. Consumption is so exaggerated that renewables are insufficient during demand peaks, Using fossil fuels like coal or gas ( esteem That, the 200,000 Colossus GPU consume 300 MW, enough to feed 300,000 homes) and, as we said, the Water use has become discussion material in the candidate territories to house new data centers. So much dissipation needs China to already Building at the bottom of the ocean. In Xataka | China wants to become AI world engine. … Read more
