wants to extract infinite energy from the waves

In the global race for decarbonization, humanity has managed to tame the wind and the sun, but the waves of the sea still resist it: the wave drive It is still a sleeping giant within renewable energies. Although the energy potential of waves is immense (unlike wind or solar, the contribution is continuous), the challenge lies in its effective technical use. In this scenario, Galicia has taken a step to place itself at the forefront of marine energy with Innomara project to move from theory to practice with the first floating prototype in Spain capable of connecting marine generation devices and evacuating the energy produced to land in Punta Langosteira, one of the most demanding marine environments on the planet. The project. It consists of designing, manufacturing and installing a next-generation floating prototype, a floating multi-connector with integrated sensors that will act as a central hub: it will connect multiple marine electrical generation devices and evacuate the energy produced to land through a single line. In addition, it will also integrate sensors to monitor in real time the waves, wind, currents, tides and marine biodiversity in the waters of the Outer Port of A Coruña. Why is it important. Because Spain is one of the leaders in solar and wind energy but in wave driving it is still in its infancy: as explains the XuntaInnomar is the first system of its kind in the state as there is currently no marine energy experimental zone in the country with a similar multi-connector. The extracted energy could be used for self-consumption in the port of A Coruña and the surrounding industrial estates, contributing to the energy decarbonisation of the port environment. More generally, this prototype allows companies to validate their projects in a real environment and speed up the development of their own patents in a sector with enormous growth and export potential, which means taking a step towards energy and technological sovereignty. Context. Wave energy is one of the great pending issues of the energy transition: the technology to exploit it has been in the research phase for decades without making the commercial leapAmong the main problems, the unpredictability of the waves (yes, they are constant, but they vary in height, rhythm, direction) and the harsh conditions of the marine environment when designing and maintaining it. However, recently we have seen promising initiatives in the United States and in Japan. And be careful, Europe is also taking the race seriously: United Kingdom, Portugal either Denmark They are investing in similar test zones. In this scenario, Punta Langosteira is a first-rate strategic asset: as explained by MITECO and IDAE in the official roadmap of offshore wind and sea energy in Spain, is considered the second area in the world with the highest concentration of wave energy, only surpassed by the south coast of Wales. Bottom line: if it works there, it has a good chance of doing it anywhere else in the world. In detail. The prototype will function as a smart laboratory on the high seas: with an underwater cable to bring electricity to land, sensors to monitor biodiversity and the marine environmental environment, and it will also be a kind of testing platform where different components can be tested. The project has been promoted by Inega (Energy Institute of Galicia) and its budget amounts to 5.7 million euros, of which 60% is financed with FEDER funds. There are seven companies that have submitted candidates for the prior selection, whose award is scheduled for September 2026, following a Public Procurement of Innovation model. Yes, but. The location is magnificent, the European co-financing provides solidity to the project, the model between the Administration and the private sector provides the best of both worlds and also the multi-connector hub approach is technically intelligent since it reduces redundant infrastructure, lowers costs and allows testing several wave converters in parallel. In short, they have everything in their sails, but the technical challenge is immense. Furthermore, the prototype is still a connection and measurement infrastructure, but it does not generate energy. Effective generation will depend on the devices that connect to it in the future, technology that is still far from being commercially mature. And here again the unknowns and viability appear again, since the cost per kWh of wave power is notably above wind and solar. That there is interest from the main actors is good news, but it does not imply that the leap to an effective solution is just around the corner.

the plan to send infinite energy to Earth

In the global energy transition there are countries and countries. There are some that are more advanced and others that are not so advanced. And although the ease of access to classic fossil fuels works as an anchor to resist change, the fact that you have not been dealt the best cards in terms of natural resources does not help either. Japan is one of those countries where change is almost a matter of survival: little land available, it matters about 90% of its primary energy and if we talk about resources, is testing the wavesbut the wave drive It’s a tough nut to crack. So Japan has decided to look at the energy transition from a spatial perspective, that is, capturing radiation outside of Earth, where it is more constant and powerful. We already saw it with his Ohisama satellite and now with his Moon Ring for, like says Beyonceput a ring on the moon in the shape of a solar plant. The idea. The proposal consists of installing a continuous belt of photovoltaic cells along the equator of the Moon covering a circumference of 11,000 kilometers, thus ensuring that a part of the structure is always exposed to direct sunlight, that is, 24/7 energy generation. From there, the electricity is converted into microwaves and high-density laser beams to be sent directly to receiving stations on Earth. What you propose Shimizu Corporation It is not so much a closed project with a specific date, but a long-term engineering vision to guide its line of research in space energy and this private company is not alone: ​​it has institutional support in the Japanese Aerospace Exploration Agency, which He’s been researching it for decades.. Shimizu Corporation Operating Diagram Why is it important. Because global energy demand continues to grow and terrestrial solar energy has important limitations in the form of the day and night cycle, clouds or the atmosphere itself, which reduce its performance. A plant at the equator of the moon would solve all three in one fell swoop: continuous solar energy, without the atmospheric filter or the risk of a cloudy sky. This is simply impossible on Earth. The European Space Agency has already recognized the strategic potential of space solar energy in your Solaris program. The eventual materialization of this project represents another step in the “Hydrogen society“, the vision of an economic ecosystem where hydrogen replaces fossil fuels as the main energy vector, arising from Japan’s need to overcome its extreme dependence on energy imports. In context. The idea is not new by any means: back in 1968 it already occurred to the American aerospace engineer Peter Glaser, who published an article on the subject in Science magazine. Much has happened since then and numerous governments and space agencies have also studied its feasibility: NASA did it in ’79, the British government has been exploring the idea since 2021 and China plans a demonstration in low orbit in 2028 followed by a test in geostationary orbit by 2030. Shimizu takes it a step further: he has moved it from Earth orbit to the moon, which brings certain geometric advantages, but also increases logistical complexity. In detail. Bring materials from Earth to space It’s not exactly easy or cheap.so their idea is to build the solar panels mainly with resources extracted from the lunar soil itself, using autonomous robots operated remotely. The solar ring would cover the lunar equator with a width of up to four hundred kilometers. The energy would be transmitted to Earth via a microwave antenna twenty kilometers in diameter, guided by a ground beacon for precise pointing. The concept of wireless power transmission is not science fiction: California Institute of Technology performed in 2023 a demonstration in orbit. Yes, but. We are facing an engineering project on a scale unprecedented in the history of humanity and the cost of launching cargo into space is the least of the problems (it is being reduced thanks to operators like SpaceX): so would building an infrastructure of these characteristics in situ. And even if it could be done, cosmic radiation and micrometeorite bombardment on the lunar surface would constitute a serious risk to the integrity of the panels, which implies a challenge in terms of useful life and maintenance. NASA itself points out these barriers in evaluating the space solar energy concept.

Our brain is “rotting” based on infinite scrolling. Someone has left their cell phone for 14 days to see if there is a way back

Today it is a reality that most of us live glued to a screen, and this is something that is documented in studies that point out, for example, that on average we review an average of 200 times the phone throughout the day, which is equivalent to looking at it approximately every five minutes. In fact, 46% of users consider themselves “dependent” on the device and 53% say they have never spent more than 24 hours without it. But what really happens in our heads if we decide to cut corners and return to the analog era? A test. To answer this question, CNN journalist Bill Weir decided to test this premise to commemorate Apple’s 50th anniversary. In this way, for 14 days Weir kept his iPhone in a box and replaced it with a basic phone like the ones we had 15 years ago, with which we could only send SMS with a non-touch keyboard and a low-resolution camera. From here the sensations he had were observed, but a group of scientists behind him were also monitoring his brain through brain scans. The results. After two weeks of disconnection, the journalist’s reaction times improved by 23%, and his brain activity also increased significantly, causing his brain connectivity to become more coordinated and organized. Subjectively, Weir experienced a much better recovery in his ability to concentrate and also noted a sharp decrease in the need to consume social media after the first week. The changes. It is no coincidence that the term “brain rot”, translated as brain rot, was crowned the neologism of the year in 2024 for the Oxford dictionary, since it is a concept closely linked to be swiping all the time with your mobile. And clearly the excessive use of smartphones and all the applications they contain is leaving a physical mark on our brain anatomy. It’s proven. MRI-based research, including a National Library of Medicine publication in 2023, they point out that problematic smartphone use is associated with a reduction in gray matter in the brain. And if we go into something more specific, it was seen that there was a smaller volume in the anterior cingulate cortex, the orbitofrontal cortex, the fusiform gyrus and the striatum. These areas are fundamental for emotional regulation, decision making and impulse control, making these alterations similar to those observed in addictions to harmful substances such as drugs. And supported. A study published in 2025 analyzed individuals for 72 hours without a mobile phone using functional magnetic resonance imaging, and the results indicated that withdrawal triggered brain activations identical to those of addictive withdrawal syndromes, followed by notable cognitive improvements. Digital amnesia. Beyond anatomy, our daily cognitive abilities are in free fall, and science suggests that the average attention time before an interruption has gone from about 2.5 minutes to about 47 seconds, blaming the accelerated digital pace here. And the culprit again is the smartphone, since a study published in 2017 analyzed to 520 participants and demonstrated that the simple presence of the smartphone on the table, even face down, consumes and exhausts our cognitive attention resources. This is why we should opt for better control of the time we dedicate to social networks or the smartphone in general, since the benefits of quitting are many.

We have been dreaming of infinite “solar gasoline” for decades. A new material inspired by plants has just proven that it is possible

Nature has been keeping a secret in broad daylight for millions of years: photosynthesis. For decades, science has pursued the dream of replicating this process to create clean, sustainable fuels, but “artificial photosynthesis” has always run into walls of inefficiency and technical complexity. Until now. In short. A team of Chinese researchers has developed a method that mimics the natural process of transforming carbon dioxide (CO2) and water into the basic components of gasoline. We are no longer talking about abstract theory; It is a system capable of creating “solar fuel” without depending on expensive chemical additives, bringing us closer to the holy grail of renewable energy. The advance, recently published in the magazine Nature Communicationscomes from a joint team of the Chinese Academy of Sciences and the Hong Kong University of Science and Technology. Researchers have designed a new composite material: tungsten trioxide modified with silver atoms (Ag/WO3). The end of chemical “tricks”. The truly revolutionary thing about this “magic dust” is not only its composition, but what it manages to avoid. To date, most attempts at artificial photosynthesis cheated: they used “sacrificial agents”, organic chemical additives (such as triethanolamine) that facilitated the reaction but were irreversibly consumed in the process, making it unsustainable and expensive on a large scale. This new system breaks that barrier. According to the scientific studythe catalyst achieves the light-driven conversion using only pure water (H2O) as an electron donor. No additives, no tricks. The result of this reaction is the efficient production of carbon monoxide (CO). Although it sounds like a harmful substance on its own, in the chemical industry this molecule is pure gold: it is a key intermediate that, mixed with hydrogen, forms the “synthesis gas” necessary to manufacture complex hydrocarbons such as methanol or synthetic gasoline. Air fuel. We are at the gateway to “solar fuels.” The importance of this finding lies in its ability to decarbonize sectors that electric batteries cannot easily cover, such as commercial aviation or heavy shipping. Furthermore, the researchers stand out in their paper who have come up with a “universal strategy”. Its material (Ag/WO3) is not an isolated invention, but a versatile “charger” that can be coupled to various types of catalysts (such as cobalt phthalocyanine, C3N4 or Cu2O) and improve their performance drastically. In fact, by combining this material with cobalt (CoPc), they achieved an efficiency 100 times higher than that of the catalyst acting on its own, equaling the performance of old systems that used polluting additives. It is a pure circular economy: capturing the gas that warms the planet (CO2) and turning it into a valuable resource. The secret is to imitate the leaves. To understand how they have achieved this, you have to look at a tree leaf. In natural photosynthesis, the processes of breaking down water and fixing CO2 are separate. Plants use a molecule called plastoquinone (PQ) to temporarily transport and “store” electrons excited by the sun before using them, acting as an energy buffer. Without this buffer, the electrons would be lost before they could be used. Chinese scientists asked themselves: “Can we build an artificial plastoquinone?” And the answer was tungsten. The developed material works as a bioinspired cargo reservoir: The battery: Under sunlight, tungsten changes its chemical structure (a valence swing from W6+ to W5+), temporarily trapping electrons as if it were a micro-battery. The bridge: When the system needs energy to convert CO2, the silver (Ag) atoms act as a bridge, releasing those stored electrons just at the right moment to recombine with the “gaps” of the catalyst. This solves the big problem of artificial photosynthesis: time and load management. While the water oxidizes, the system “saves” the solar energy to have it ready when the CO2 enters. From the laboratory to the real world. The best thing about this research is that it has not remained a theoretical simulation under perfect lamps. The team built an experimental device equipped with a Fresnel lens (to concentrate light) and took it outside to test it under natural sunlight. The data from the outdoor experiment are revealing: Solar rhythm: The system began to produce detectable gas from 9:00 a.m., reaching its peak production between 1:00 p.m. and 2:00 p.m., faithfully following the intensity of the sun. Durability: The system demonstrated enviable robustness, maintaining its effectiveness over 72-hour test cycles without showing significant downtime. A bridge to the future. As reported by the South China Morning Postthis advancement builds a critical bridge between renewable energy and high-demand industrial applications. The study authors conclude that their work not only eliminates the need for unsustainable sacrificial agents, but provides a versatile design principle for building autonomous photocatalytic systems. Although there is still a way to go to see solar gas stations, the basic science—the mechanism for storing the sun’s energy in a chemical powder—is no longer a theory.

Wall Street has turned on the spigot of infinite money for AI. They have forgotten a small detail: the electrical network

In that equation that the world is trying to solve with AI, there is a half that not many people have noticed: debt. Behind every AI-generated chat and video is a gigantic network of data centers, and those data centers are being financed with a mountain of borrowed money. And therein lies the problem. In what is borrowed. Debt and more debt. According to recent datathe issuance of secured debt linked to data centers in the United States is estimated to be $25.4 billion by 2025. It is 112% more than the previous year. If we add up all the complex financial instruments (known as asset-backed securities (ABS) and commercial mortgage-backed securities (CMBSS)), the snowball is already huge: there are almost $49 billion tied to these securities. Bonuses for everyone. Here there are not only startups asking for loans, no. The technology giants that are setting up these infrastructures – the so-called hyperscalers – are also taking advantage of this mechanism. Companies such as Microsoft, Google, Oracle or Meta have rediscovered the bond market as a source of financing. Better to spend what is not mine. They all have huge amounts of money, but instead of spending their own cash, They have raised 100,000 million dollars in debt issues so far this year. The goal: buy thousands of GPUs and build data centers before the competition. What are you doing, Oracle? If there is a company that embodies the vertigo of this excessive bet, it is Oracle. The company created by Larry Ellison has committed to meeting a Pharaonic $300 billion deal with OpenAI. That has forced it to become the largest issuer of corporate debt (outside the financial sector). The numbers are scary: your total debt has grown to 111.6 billion dollarswhile its cash has dropped by 10,000 million. Citi estimates they’ll need to borrow another $20 billion to $30 billion every year (every year!) for the next three years just to keep building. excessive ambition. There are also examples of startups that are exploiting this facet. One of the clearest is the one from CoreWeavea company famous for renting computing capacity for AI. The company has secured credit lines of $2.5 billion backed by leading investment banks such as JPMorgan. The market message seems clear: “if you’re going to build for AI, here’s the money.” How to get a 30-year mortgage. Analysts of all kinds have been keeping the fly behind their ears for some time, and one of the latest Moody’s reports is a good example. Concrete buildings are usually financed with terms of 20 or 30 years, but the technology inside (such as AI chips) changes radically every 3 or 4 years. Does it make sense to go into debt three decades from now for a technology that evolves so quickly? cheap money. Investors are also agreeing to charge minimal interest, just 1% above what the safe US public debt pays, when they assume that risk. It’s a worrying classic sign of euphoria. There is so much money wanting to enter the sector that those who lend it have lowered their guard and demand very little return for their risk. They firmly believe in the promises of AI while increasingly more analysts warnhorrified, that we are facing an “irrational exuberance.” Having money is no longer enough. All this is already scary, but the real bottleneck for expansion is not even capital or chips, but the electrical grid. As Satya Nadella, CEO of Microsoft, pointed out, there is no power for so many chips. The situation is so worrying that a Deloitte study indicated in a study that there are a seven-year waiting line to connect some data center projects to the electrical grid. And if companies want to obtain financing, they need have guaranteed electricity supply for your data centers. If there is no plug, there is no loan. Big Tech looks for electrons. At OpenAI they already warned of the problem months ago when talking about the “electron gap” describing electrons (energy) as the new oil. Almost all the major companies in the industry are making a move. Google has signed an agreement with TotalEnergies to be delivered 1.5 TWh of electricity over the next 15 years, and Meta did something similar with Treaty Oak Clean Energy to get 385 MW of its solar plants in Louisiana. The bubble before the big question. All of this further increases the fear that the AI ​​bubble will end up bursting in a big way. Meanwhile, the big unknown is whether the demand for artificial intelligence will be capable of paying the immense electrical and financial bill that it is signing today in 5 or 10 years. The credit party continues. In Xataka | While Silicon Valley seeks electricity, China subsidizes it: this is how it wants to win the AI ​​war

It doesn’t give you infinite options so you don’t even think

Mercadona sells more choosing for you. While chains like Carrefour Abruman with up to 20,000 references, Mercadona triumphs in quota and profitability, among other reasons, thanks to their less than 10,000 carefully selected references. The Valencian chain has turned the selection and reduction of catalog into an advantage: by offering less options, eliminates decision fatigue and increases its margins. Why is it important. Mercadona has achieved A net margin that touches 3.9%well above the rest of his rivals. Applies what we could call “spotify formula” to retail: Select and screen instead of accumulating. That also allows you to get more rotation, more control and more margin. The panoramic. Eroski, Carrefour, Alcampo … bet on the variety. Mercadona bets on the selection. It operates with what we could call an “efficient assortment”, based on their own brands developed with what they call their “Totaler suppliers“ It controls so much what is manufactured, as the “how” is manufactured, such as what finally reaches the linear. Spotify avoids navigating among millions of songs with very specific and refined recommendations. Mercadona filters between thousands of products and chooses by the consumer reducing their options. That translates into less than 10,000 products per store in front of competitors that double that amount. Assorted reduction is a general trend, but Mercadona is the one who has opted the most in the last five years (-45% assorted compared to -31% of Eroski, -20% of Carrefour or -14% of Lidl), according to a Kantar study cited by Interempresas. The context. Psychology supports it. Barry Schwartz showed that having too many options can be an initial hook, but When executing they overwhelm us. Is The choice paradox. Reducing them also reduces friction and decision -making time. Less products, less decision fatigue, more satisfaction. In detail. Where you used to choose between eleven oils or six snacks, now choose between two or three. The client, if he trusts, does not have to compare. Do not spend mental energy. Just buy, and continue. Yes, but. The model also has costs. Mercadona withdraws products quite frequently if they do not fit their expectations. Some would be pleasantly popular on other surfaces, but they are not enough in the Mercadona model. It is something similar, since we talk about technology, to what happened with the iPhone Mini: they had around 5% of the annual sales share of the iPhone, something celebrated for many other manufacturers, but Not for Apple, who discontinued him After two generations. Mercadona has not invented the selection and screening, but it has refined the technique of applying it to the supermarket. Deepen. Choosing for the client can be seen as a paternalistic movement, but Mercadona has made it efficiency. When there is overabundance in the environment, well -designed shortage is power. In a world that usually rewards accumulation, Mercadona wins simplifying.
