In Europe, gas and disused coal plants have unexpected suitors: technology companies

by

The climatic commitments that It has acquired Europe They have condemned in the short or medium term the future of gas and coal power plants disseminated by the old continent. Many of them no longer serve, but, surprisingly, the rise of the artificial intelligence (AI) has the ability to save them. This does not mean at all that they will burn gas and coal again; The option on the table is to convert them in data centers. Microsoft and Amazon are, According to Reuterstwo of the large technology companies that are interested in transforming these old power plants into modern data centers equipped to the last one. In fact, its managers are already negotiating with the French energy company Engie, the German RWE and the Italian in the possibility of using their facilities for this purpose. For energy companies this option is very attractive because it allows them to kill two birds. On the one hand, the transformation of their old electric power plants into data centers guarantees them in income with which they did not count so far. And, in addition, the energy companies that I have mentioned in the previous paragraph and some others are negotiating with the technology companies the possibility of give them the supply of electricity that require your data centers. A priori seems like a fissure plan. An agreement in which everyone wins “You have all the necessary pieces, such as water infrastructure and heat recovery.” This Bobby Hollis statementVice President of Energy in Microsoft, repairs something very important: the old gas and coal centrals that are no longer operational have the water supply and the heat management infrastructure that data centers need. Presumably it will not be necessary to undertake a large adaptation to transform these facilities into operational data centers. Agility when putting up these data centers and moderation of costs is what makes them so attractive to large technology On the other hand, Lindsay Mcquade, director of Energy for the EMEA area (Europe, Middle East and Africa) at Amazon, Trust in that the permits that technology companies need to operate these converted data centers are available long before the new facilities. After all, most of Infrastructure are already installed In these buildings from the beginning. In fact, agility when pointing out these data centers and moderation of start -up costs is what makes them so attractive to large technological ones. In Europe and the United Kingdom since 2005 they have closed no less than 190 coal and lignite centralsand another 153 will follow this same path before the year 2038. It is evident that the possibility of reusing all these buildings transforming them into data centers for AI is very attractive. However, there is a challenge that is not yet resolved and that can condition this plan. It is not clear that the electrical infrastructure of some countries is capable of delivering The energy required by these facilities without previously undertaking a large -scale development. In this scenario renewable energies and nuclear will have the last word.

The world of technology is no longer “the seven magnificent.” Now that scepter has “the Trinity of AI”

by

The world of cinema has some fixation with number seven. It is demonstrated by the mythical ‘The Seven Samurais‘(1954, Akira Kurosawa) which would then be adapted to the genus Western with’The magnificent seven‘(1960, John Sturges). The idea ended up moving to the business world and for a few years there has been talk of “The magnificent seven“In reference at seven most important technology companies in the world. Well, that number is no longer so relevant. It seems that we will have to change it for a three. The four billion club. Last week Microsoft became the second company in the world to achieve a stock market capitalization of Four billion dollars. Just two weeks before Nvidia had been advanced. Both have climbed into the AI car and benefit widely from it, but there is a third leading protagonist that is still far from that milestone but that goes like a rocket. The 10 companies with the greatest stock market capitalization today. Goal is far from the four billion, but its recent growth is spectacular. Source: CompaniesMarketcap.com Goal. The recent ones Financial results presented by goal served to make the company redouble their commitment to this segmetno. Those responsible spoke of a much larger capex than expected that will rise to 66,000-72,000 million dollars. That, added to all movements they are doing to sign talent and creating a new superintelligence team have caused remarkable optimism among investors. Meta actions rose more than 10% after these ads, although in recent days their value – like that of their competitors – has reduced significantly. We have gone from “the magnificent seven” … In recent years that list with the most important companies in the world (by stock market capitalization) was dominated by large technological ones. Among the first 10-15 positions were always those “seven magnificent”, namely: Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia and Tesla. All of them remain very relevant, but the rise of AI has changed the panorama. … to “the trinity of the AI”. Dec Mullarkey, manager at the Capital firm SLC Management, He spoke How “the Magnificent seven have compressed (and became) in the Trinity of AI.” The expectation that these companies do not stop generating remains extraordinary, and that has made investments and interest in these companies absolutely triggered. Overvalued? The Ratio P/E (also known as Per, Price to Earnings Ratio) is a metric that evaluates whether an action is expensive or cheap in relation to the benefits of the company. A high P/E means that investors expect a high growth of benefits, and a low one may indicate that the action is undervalued. According to this metric, Tesla is very, very overvaluedwhile Google is relatively undervalued with respect to its competitors. The companies of “The Trinity of AI” are somewhat overvalued. Graph: Xataka. Data: Companymarketcap.com Google’s mysterious case. It is strange that in that “trinity of AI” is a goal but not Google, which at least in practice is much stronger: His family of Gemini models is more capable than those who have a goal, for example, but for now, investors do not seem completely convinced of their ability to lead that segment. The situation of Amazon and Apple It is very different: both have made their respective bets, but they are still very relegated in that AI race.

China increasingly dominates technology on earth. There is a place where they are still far from Occiden

by

A recent report The New York Times He has evidenced the Chinese difficulty to compete with Spacex in the deployment of communications satellites. While Musk’s company already accumulates 8,000 Starlink satellitesthe two main Chinese networks just add 120 units in orbit. Why is it important. Low orbit satellites are strategic for autonomous cars, war with drones and military surveillance. China considers Starlink a direct threat and has planned two megaconstellations with 27,000 satellites between them. Qianfan, the constellation of low orbit satellites developed by China, anticipated having 650 operating satellites at the end of the year. Shanghai Spacesail Technologies, the company after the project, has only managed to put 90 in orbit since August. Guowang, an alternative born in 2020, is even worse: 34 satellites of the 13,000 planned for the next decade. The context. The Popular Chinese Liberation Army See Starlink as something “deeply integrated into the US military combat system”. It is not empty paranoia: this network is essential to coordinate drones in Ukraine and Spacex has government contracts for spying and missile monitoring. The background. China has not solved the key problem that Spacex solved years ago: reusable rockets. Chinese companies continue to wear single -use pitchers, which multiplies costs and reduces the frequency of launches. The Falcon 9 can reuse its first stage up to 20 times, greatly reducing the costs. After five hundred missionsit is still the reference. Chinese candidates –Long March 8R, Zhuque-3, Tianlong-3– accumulate failures and delays. Yes, but. China is negotiating Contracts with 30 countries to access Qianfan. He has already signed agreements in Brazil, Thailand, Malaysia and Kazakhstan, taking advantage of certain misgivings towards American technology dependence. The rhythm of Chinese launches accelerates: more than thirty missions in the first half, putting 150 satellites in orbit. But they need to multiply by five or six the rhythm to fulfill their international radio frequency commitments. In addition, there are some counterparts to your proposal: The decisive moment. Chinese megaconstellations must launch half of their satellites in five years after obtaining the frequencies, completing the deployment in seven. Not fulfilling could force them to reduce the size of the networks. Main loser? China dominates manufacturing, batteries, solar panels and traditional (non -advanced) semiconductors. But in sectors that require maximum risk assumption – Biotechnology, the space – the United States maintains a decisive advantage. Getting smaller in some scenarios, but maintains it. The business mentality that rewards rapid and cheap failures against guaranteed successes makes the difference between Spacex and its Chinese rivals.

Airplanes have been depending on GPS for decades. Some engineers have another idea to replace it: quantum technology

by

Airbus and the company derived from Google focused on quantum technology and IA, Sandboxaq, have completed more than 150 flight hours Testing Magnava revolutionary system that uses Quantum sensors to detect the unique magnetic “fingerprints” of each point on the earth. The initial results have been promising, and are a sign that technology could rival the Traditional GPS and even overcome it in precision. Why is it relevant. The GPS has become the Achilles heel of modern aviation. Interference attacks and Spoofing They are dramatically increasing in conflicting areas such as the Middle East, Ukraine and Russia, and this It also affects civil flights. The military use these techniques to confuse missiles and drones, but the consequences extend dangerously to commercial aviation. Hence the importance of looking for a viable alternative to GPS. Magnav. Image: Sandboxaq The secret of its operation. Magnav has more or less the size of a toaster, and has a laser that shoots photons against electrons. When the laser goes out, these electrons release the absorbed photons with a unique energy firm that reflects the intensity of the earth’s magnetic field in that exact location. An artificial intelligence algorithm processes this information and compares it with detailed magnetic maps to determine the position of the plane. Each square meter of the planet has an unrepeatable magnetic firm, created by the iron particles of the earth’s core that magnetize the minerals of the cortex. More precision and more difficult to supplant. Unlike GPS, which depends on vulnerable digital signals from satellites, quantum sensors are completely analog and process data generated entirely on board. Jack Hidary, CEO of Sandboxaq, Explain that this makes them “essentially impossible to interfere or supplant.” During the evidence, Magnav managed to meet the standards of the Federal American Aviation Administration 100% of the time, maintaining precision within 2 nautical miles. Even more impressive, it reached a 550 -meter accuracy in 64% of the occasions. Beyond aircraft. The experts They predict A quantum sensor market valued between 1,000 and 6,000 million dollars by 2040. This technology promises to detect submarines and hidden tunnels in defensive applications, and weak magnetic signs of the heart and brain in medicine, allowing non -invasive diagnoses. Joe Depa, Global Innovation Director of EY, Underline That “we are not talking about something within 20 years, but about something that is here and now.” The next step. Sandboxaq plans to go first to the defense sector before expanding to commercial flights. Although more evidence and certifications are required, Hidary stands out that have overcome “the difficult part: demonstrate that technology works.” According to him, it is the “first novel absolute navigation system that we know in the last 50 years.” Cover image | Ross Parmly In Xataka | The 777x is Boeing’s great bet to return to the top: folding wings, redesign cabin and the largest engine in the world

The model that dominated technology for 50 years has died

by

The numbers do not usually lie, especially in the long term. And Intel’s figures during the last decade speak of a historical replication. Of A giant come less in an alarming way. In figures. In 2015, Intel’s stock capitalization multiplied by Nvidia. Almost ten years later, that of Nvidia, the first company in history to exceed four billion dollars, multiplies by 41! to Intel, which has been jibarized at a time when it has been exceeded by many lower companies. A brutal change that symbolizes the change of technological era: Nvidia’s boom first for its GPUS sales for cryptocurrency mining and then for the training of AI models. Intel’s decline due to its inconsequence in the mobile era, the rival boom in CPUS, or the passage of Microsoft or Apple to ARM. And not only Nvidia has advanced. Also Texas Instruments, Qualcomm, AMD … Gelsinger’s legacy. The contrast. In 2006, Intel refused to make chips for the iPhone Because I considered that Apple was too small. That same year, Intel tried to buy Nvidia For 20,000 million dollars, but Jensen Huang refused. Today these decisions have completely checked Intel’s route, which at the beginning of the century was always in the top 10 of world companies by stock market and today is close to leaving the Top 200. The threat. The Hard recent admission of CEO Intel, Lip-Bu Tan, that Intel is no longer among the top 10 of semiconductors, says many more things. The company that fed the PC revolution, which created the Wintel ecosystem that dominated for decades and was synonymous with American innovation, now is worth less than Spotify, Coinbase or Iberdrola. Yes, but. The 5,500 new layoffs announced by Intel They are more than an adjustment or cut. In California, almost 2,000 jobs will disappear. In Oregon, almost 3,000. In total, 20% of the workforce will be fired. The workers who developed the technology that moved the world are now expendable. The turn. Intel has outsourced TSMC 30% of its production by 2025. Paradoxical in a company that presumed its vertical integration, which controlled from design to manufacturing. And that now depends on his Taiwanese rival to survive. A symbolic surrender: the king of manufacturing asking for help to who removed the throne. Between the lines. The strategy of pivoting to the edge announced by so sounds like last minute refuge. “It’s too late for us“The CEO admitted. It is not only to recognize the loss against Nvidia, it is to recognize the loss in the most important race of what we have been from the century: that of AI. And another paradox: China represents 29% of Intel’s incomemore than any other market. The most iconic American technology company depends more on China than its own market. Trump is focused on technological independence in this legislature … … but Intel needs China to stay alive. Turning point. He 18A process That must save Intel by 2025 generates certain doubts. And if he fails, Intel runs out of his last asset to compete with TSMC. If it triumphs, it will be a partial victory, since it will be arriving five years late to the battle. This Intel fall also symbolizes something else: the end of the vertical integration model in chips represented Intel against Nvidia’s specialization model. The first designs and manufactures. The second designs but leaves manufacturing in the hands of TSMC. And hence the problem for the West: advanced manufacturing is concentrated in Asia and the value is redistributed.

China has a key technology to create a more effective antimisile shield than the iron dome: a beetle

by

During the recent one Conflict between Israel and Iran There was a lot of talked about the powerful Israeli antimile defense system, known as the ‘Iron dome’. Europe too wants to build yours and United States shuffled the creation of a ‘golden dome’ that would use a satellite network and would be able to Stop hypersonic missiles. And what about China? Although they have Several antimile systems At different levels, they do not have a “total” shield like the one who wants to build the United States. What they do is a technology that, if applied, would far exceed the detection of missiles from other countries. A beetle. This kind of beetles receives that name for its ability to detect fire up to 80 kilometers away Thanks to an organ in its most sensitive exoskeleton than most infrared sensors in the market. This has been the inspiration of these Chinese researchers for their new creation: a system that mimics this same sensitivity and allows you to detect hot objects quickly and precisely. The system. During the investigation, Posted in Nature magazinethe scientists carried out several tests to verify the effectiveness of the system. In the first they built an ‘heteroestructure’ with divel -divelur, a material that offers a high absorption of the middle infrared range, and pentacene, an organic semiconductor. The device could detect radiation to an intensity of only 0.5 millivats per square centimeter, a sensitivity close to that of the beetle. In the second test they used black phosphorus and Indian seleniuro, achieving a photonic memory of 0.5 microseconds, 20,000 times faster than conventional optical storage. Capacities. Researchers affirm that this technology is able to “detect and identify objects in difficult environments, since it can penetrate obstacles such as smoke, fog and dust, providing clear images and precise detection of objectives.” In addition, it works at room temperature without refrigeration. This technology could be used in various scenarios: fire detection, autonomous driving, night vision systems and of course military environments. Antimisiles. As we said, China does not have an “dome” antimile system, but this technology could open the door to the creation of one that, According to South China Morning Postit would be much more precise than the ‘Golden Dome’ that Donald Trump wants to build. The key point is that the system integrates detection, memory and processing functions. Current antimisile systems are based on traditional silicon semiconductors and hardware separation (sensors and processors) prevents them from reaching those response speeds. Nothing concrete. Donald Trump’s ‘golden dome’ is, for now, a proposal that has not yet materialized, just like this hypothetical Chinese dome. What we do know is that China did not make any grace The announcement of this project because “it would raise the risk of converting space into a war zone and creating a career for creating space weapons.” Currently, China has several antimile defense layers: Dong Neng-3an exoatmospheric missile interception system, HQ-19 for medium-range interception and HQ-29 with antisatelite capabilities.

The US prepares to bomb the border of Mexico with sterile flies. It will not use genetic engineering, but 1950 technology

by

The United States wants to stop the Cochliomyia hominivorax, A fly that when it is in the larval phase causes a parasitic disease that mainly affects cattle (although it can also affect humans). A few days ago we talked about the plan to end her: launch millions of sterile flies to stop their expansion. The funny thing is that they are not going to do it using Genomic editionbut for this they will use a technology ago. X -rays and planes. The objective of this initiative is to stop the expansion of this plague and for this what they are going to do is sterilize millions of flies. As? With A technology that has been using since the 70s To combat this plague: X -rays. After raising the larvae and that they transform into pupae, they are placed inside a metal cylinder that is introduced into a gamma irradiation chamber with a dose of between 40 and 65 gray, enough to reach 95% sterility without compromising their survival. The container (left) that is introduced into the irradiation chamber (right). Fountain Once sterilized, you have to reach the affected areas, in this case the southern Texas and Mexico. To ensure that they arrive in the appropriate phase, the pupae remain at 10 degrees so that their metamorphosis to adults slows down. They are released from airplanes and, when the temperature rises, sterile males emerge. Why not transgenic flies? Sterilization of insects by radiation has decades of proven efficacy. Genetic modification is potentially cheaper and efficientbut it is still in an experimental phase and is not ready for mass production. There is also the issue of regulation, more complicated in this case because it requires approvals from two countries: the United States and Mexico. The current legal framework under which sterile insects are released does not contemplate genetic modification and achieve approval I could take years and cost millions of dollars. The threat. The one known as “Cattle Barrenter” is a devastating species, especially for cattle. The females deposit their eggs in wounds and mucous animals and, when hatching, the larvae begin to feed on the meat, causing injuries that become mortal. According to the head of the American Association of Veterinary Medicine, They can kill a 450 kilos cow in two weeks. This pest affects mainly to countries in South America, but It is not the first time that the United States has to deal with it; In 1966 they already eradicated it and in 2017 there was a small outbreak in the Florida Keys. There is a hurry. Although the reduction of transgenic technique costs sounds attractive, the reality is that there is no time to lose. The boreride worm has reappeared in southern Mexico and, although it has not been detected near the border, from the United States They don’t want to take risks.
