The waves are disappearing and we already know what causes it

by

Imagine that one morning, one of the most famous natural wonders in your region disappears. It is not progressively lost, it simply ceases to exist from one day to the next. This is exactly what happened in October 2003 in the Basque thing. The Mudanka waveconsidered one of the best lefts in the world and an economic pillar for the area based on surf tourism, stopped breaking. The cause. It was not a mystery: a dredging of 243,000 cubic meters of sand Oka riverexecuted to facilitate the passage of barges to a shipyard, undid the underwater sandbank that, like a reef, sculpted the wave. The surf sank, and with it the local economy, which was based on surf tourism. This event is the starting point of ‘Las Olas Perdidas’, an investigation and exhibition at the Botín Center in Santander that unites the duo of artists and researchers from Cooking SectionsDaniel Fernández and Alon Schwabe, with the geomatics and oceanography group of the University of Cantabria. The project reveals an alarming truth: the oceans are losing their waves, becoming calmer, and we are the reason. Traveling in time. Just like the two researchers have recognized to ABC, although it seems impossible that the waves will end up disappearing, the reality is there. They point to the seas and oceans being calm and losing their strength. To demonstrate this, the GeoOcean team from the University of Cantabria applied its modeling technology in a novel way. According to the artists, they discovered the scientific group’s “ability to travel through time” to be able to see the waves that seemed to be only in the memories of the surfers. By using satellite imagery, historical databases, and complex numerical models, GeoOcean was able to do something amazing. “We indicated a day, month and year and they were able to show the height, speed or direction of the waves perfectly,” explains Fernández. All this with technology that today is used to predict future storms and the impact they may have on the coast. Although going back in time. The objective. Seeing exactly what was happening in the past made it possible to compare the state of the mythical wave before and after the key intervention that led to its eventual disappearance: a new breakwater. The conclusion in this case is that at the moment of ‘touching’ the seabed with any building or by simple trawling, the damage is caused by the wave. The investigation, which lasted two years, analyzed cases on all continents, including mythical enclaves now disappeared or degraded such as Cabo Blanco in Peru either Jardim do Mar in Madeira. They showed that when infrastructure cuts off the natural drift of sediment or dredging alters the seabed, the result is a loss of energy and, ultimately, the death of the wave. The injured. Logically, the fact of eliminating waves affects the surfers themselves, above all, and also the economy in general, since it is a very important driver of tourism in different regions. This has caused them to rise up on a war footing to defend the oceans and different phenomena. In Peru, for example, the protests of surfers and fishermen in Cabo Blanco were fundamental in promoting the pioneer “Law of Breakers”a unique legislation in the world that protects waves from infrastructure that could alter them. In Cantabria, groups such as ‘Surf & Nature Alliance’ are looking for formulas to declare the surf as natural heritage to prevent human hands from altering it. However, Cooking Sections warns of the other side: massive surf schools and championships that radically transform the life of a region is a double-edged sword. Surf-focused tourism and real estate speculation have fueled gentrification and, paradoxically, driven coastal development that ends up destroying the very waves that attracted people in the first place. The move to art. Science can sometimes be difficult to understand because you are working with a lot of data. That is why the team wanted to turn it into an artistic representation. Composer Duval Timothy turned the rhythms of each break before its disappearance into eleven unique sound pieces. In the room, eleven suspended structures undulate and vibrate activated by interpreters, simulating the “breathing” of those waves now extinct in order to raise awareness of the great problem that exists. In this way, ‘The Lost Waves’ uses data science to create an archive of what we have erased in the sea, demonstrating that the seabed and the surface are intimately connected and that our ‘scars’ on the ocean floor have direct consequences on the energy that materializes on the surface.

The most detailed gravitational waves in history have just confirmed the great prediction of Stephen Hawking

by

After ten years Perfecting the detection of gravitational wavesLigo sensors achieved such a precise observation which has allowed physicists to confirm one of Stephen Hawking’s most famous predictions: the black holes area theorem. Ten years. A decade has passed since the scientists of the Ligo Observatory The universe listened for the first time in a completely new way: by detecting gravitational waves. On September 14, 2015, wrinkles in spacetime tissue Predicts by Albert Einstein a century earlier inaugurated a new era in astronomy. What was then an almost imperceptible cosmic whisper, today has become a symphony that sensors can clearly hear. And on the tenth anniversary of that milestone, the Ligo-Virgo-Kagra (LVK) collaboration has captured the most clear gravitational wave signal to date. GW250114. Detected on January 14, 2025, physicists believe that these gravitational waves were caused by the collision and subsequent fusion of two black holes to about 1.3 billion light years from the earth. Interestingly, the event is almost a twin that ended using Ligo’s physicists the 2017 Nobel PrizeGW150914. In both cases, it was two black holes with masses between 30 and 40 times that of our sun. But there is an abysmal difference: the signal quality. An unprecedented sharpness. Thanks to a decade of technological improvements and advances in quantum engineering, Ligo detectors are now almost four times more sensitive. While the first signal had a signal/noise ratio of 26, that of GW250114 has a 80. “We can hear it high and clear, and that allows us Physical Review Letters. This sharpness has been key to unraveling the secrets that were hidden in the vibrations of the black hole resulting from the merger. Hawking theorem. In 1971, Stephen Hawking proposed that the total area of ​​the event horizon of a black hole can never be reduced. It can increase or remain the same, but never shrink. This, which is known as the Hawking area theorem, is analogous to the second law of thermodynamics, which says that the entropy (the disorder) of an isolated system always increases. Therefore, the area of ​​a black hole is a measure of its entropy. Trying it is complicated. When two black holes merge, part of their mass becomes an enormous amount of energy in the form of gravitational waves (the famous E = mc²). In addition, the new black hole can turn much faster, and a larger turn implies a minor area for the same dough. Does the increase in mass compensate for these losses so that the final area is always greater? The analysis of GW250114 has been settled by the matter bluntly. Hawking was right. In this case, the two initial black holes had a combined area of ​​about 240,000 square kilometers. After the merger, the new black hole, with a mass of about 63 times that of the sun, it had an area of ​​400,000 square kilometers. If in 2021 a first test with the 2015 signal showed a 95%confidence, the new data raises that certainty to 99,999%. As Kip Thorne recalls, one of Ligo’s parents and Hawking personal friend, the British physicist called him right after the first detection in 2015 to ask if they could try his theorem. Hawking died in 2018but today his theory has been verified in a way that would have left him very satisfied. Einstein too. Thanks to this new signal, scientists have been able to analyze the moment just after the merger in which the new black hole vibrates like a newly hit bell before stabilizing. The frequencies and speed with which these tones are attenuated. It is the most solid test to the date that black holes are seemingly simple objects that can be completely described with only three properties: mass, spin and electric charge. All other information of the material that formed them is lost. But each detection of gravitational waves is one more piece in the puzzle of the cosmos. And as GW250114 demonstrates, to understand them we travel on the shoulders of giants such as Einstein and Hawking.

The Los Angeles Plan to turn waves into megawatts

by

They look like piano keys dancing on the Pacific, but they are blue floats that rise and go down to the rhythm of the waves in the port of Los Angeles. At first glance, they could go unnoticed, but in reality they hide a promise: transform the inexhaustible force of the sea into clean electricity for thousands of homes. Short. The company Eco Wave Power He successfully completed The operational evidence of its first pilot project in the United States just a few days ago. The key moment was the descent to the float water, Transmitted live by Good Morning Americaa symbolic gesture that marked the beginning of the operational phase within the Energy Mix of California. The company has an ambitious plan: it wants to cover with floats the 13 kilometers of the breakwater that protect the port of Los Angeles. This installation could generate electricity for about 60,000 homes, According to Eco Wave Power press release. More in depth. The system uses eight floats fixed to a concrete dock. At first glance they seem piano keys, but their function is much more complex: with each movement of the waves, the floats act on hydraulic pistons that push a biodegradable fluid through pipes to a unit of energy conversion (ECU) installed on the ground. Inside, it works almost like a small hydroelectric plant. The accumulated pressure moves a turbine and, with it, electricity is generated. The entire system fits in two 20 -foot maritime containers, which makes it easy to transport, mount and maintain. The key is in the location. Other projects were launched inside and ended up sunk by the cost of submarine cables and the damage of the storms. Here, however, the floats are anchored in existing port infrastructure. And if you arrive bad weather, they get up as if they were retractable awnings to avoid damage. “When the waves are too high, the floats simply go up until the storm passes, so there is no damage,” The CEO Inna Braverman explained to Techxplore. But not everything is perfect waves. Undimotriz energy has been promising for decades and fulfilling little. The teams in the open sea suffered constant damage, and the repairs were very expensive. The coastal model of Eco Wave Power seems to solve part of the problem, but it is still an experimental technology. We need to check if you can compete in costs with giants such as solar or wind, today cheaper than ever. “The Achilles heel of this energy is in the maintenance and inspection costs. Therefore, to have a device near the coast, from where you can walk and review it, it makes a lot in statements collected by Techxplore. However, we must not forget the current American political context. While the federal government REduce support for green technologiesstates like California continue advancing on their own towards carbon neutrality in 2045. In that pulse, the echo pilot Wave Power works almost as a statement of intentions: although Washington goes in another direction, innovation continues to find holes to emerge. A symphony of the sea for the future. The official inauguration is scheduled for September 9 in Altema, in the port of Los Angeles, and a new chapter in the state’s energy transition is expected to mark. For now, the floats continue to move like aquatic piano keys. But if they fulfill their promise, they could compose a different melody: that of a future in which the ocean sway illuminates an entire city.

A Spaniard has patented a mast that transforms wind and waves into electricity. His invention challenges diesel in ships

by

A mast shaken by the wind, the waves pushing without rest: usual scenes in any maritime journey. The interesting thing is that the same movement can serve to generate electricity. A canary who is one step away from being an engineer has designed a system that converts the strength of the ocean into usable energy, with the ambition to reduce the dependence of the diesel in the ships. It is an idea that takes the everyday of the sea and makes it a concrete technical proposal, simple enough to intrigue and ambitious enough to demand validation in the sea. “In the end it is a three -dimensional generator,” Juan Francisco Sarmiento Medina said in an advance of the Podcast of the Stier Groupand described the mechanism with simple images: “Let’s imagine that my arm is the mast. When the wind comes in front, it clashes, as the mast of a flag, and begins to oscillate. The keel works as a piston of a combustion engine (…) then movement occurs in the x, y y y z axes, all under Faraday’s law,” he explained. That narration of the inventor itself forms the technical spine of the project. What exactly is the e-mast. In its LinkedIn account the project appears as E-MAST (Energy Mast System) and is presented as a technology that transforms the structural vibration of the mast into clean electrical energy. According to the textthe system integrates an encapsulated rotor without exposed parts, linear generators and piezoelectric elements to convert oscillations into electricity, and can direct part of the induced air under the keel in the form of microburbujas. The advantages of the inventor are clear: “Without diesel engines, or maintenance. The owner of the boat, as there are no mechanical parts that have to be maintained with oil or that are broken, also reduces costs in that sense,” He pointed to El Español. The inventor also underlines the operational silence due to the absence of external propellers and the total structural integration into existing masts. These benefits, in any case, will require trials to measure power, autonomy and acoustic signature. Of production patent. The applications of applications published by the author encompasses autonomous marine surveillance, oceanographic research, defense and ecological navigation platforms in protected areas. According to Sarmiento Medina, the e-mast is protected by two patents, ES202430338 and ES202430339, with a favorable report according to the promoter. According to the newspaper La Provinciathe promoter figure around half a million euros international protection and development and has conversations with shipyards in France and the Netherlands to explore production. The sea still has the last word. Sarmiento says that he is a neighbor of Las Palmas de Gran Canaria and recognizes that part of his learning and opportunities come from the Stier Group, which has supported his training. This local support, added to the intellectual protection that it declares in its public profile, has allowed to convert a daily element of any ship at the base of an ambitious technological proposal. Now the most difficult part remains: validate the system in the sea. But the idea has already demonstrated something important: that there is still margin to imagine new things, even in an environment as old as navigation.

This year it seemed destined to be the recovery of the crops. Heat waves and fire are changing this

by

The last years have been convulsive for the Spanish field. After more than a year suffering a drought that put many against the strings, the arrival of an exceptional humidity period between autumn of 2024 and the recent spring seemed to bring the long -awaited relief. However, the arrival of summer has brought a script. Heat and fire. The intense heat seen in recent weeks has been the climax of a remarkably hot summer, with an exceptionally warm month and one month of August on the way to be (if the imminent cooling does not avoid it). Both extreme heat, as the fires associated with this heat wave have introduced new threats For crops. Direct and indirect damages. The damage associated with heat and fire can be both direct and indirect. It is evident that fire can destroy crops whole and that heat It can also affect to the productivity of plants, but the effects are even more complex. Fire can be an indirect risk. For example, areas that have not been affected by the flames They can be inaccessible During the fires, either due to smoke or by the cut of access roads. Extreme heat can also limit the time that workers can dedicate to work abroad. To this can be added the impact that heat and fires have on the Water availabilityincreasing the ghost of water stress even after almost a period of extraordinary economic bonanza. The oil. Recently, Agricultural Associations such as Asaja, Coag, UPA and Union of Unions They pointed to EFEAGRO Some of the crops that could be more affected by heat and flames. Among them, one about to go through one of its critical points: oil. The Olivar sector fears that this season is not kind to the olive harvest. Water stress can affect the maturation of the fruit so the sector believes that the current situation could lead to olives, dynamiting the (Already scarce) Hopes to recover from the sector. The other crops at risk. The list of harvest at risk by heat is wide. Includes crops like the vineyardpotato, tomato and fruit trees. In the case of grapes, for example, lack of water can replace its phenolic maturation with maturation by dehydration, they explain from the sector, which impacts the quality of the product. Not even crops such as cereals are saved. Although a good part of the harvest has already been collected, in some areas fires can prevent farmers from finishing the collection of these crops. What is true for agriculture can also be for livestock. They are not rare the times that fires are primed with farm animals: even when the fire does not put them directly, their pastures and their abbrevics can disappear overnight. More quantity, less price. Heat and fire add uncertainty to a year marked by Important drops in prices of agrarian products. A very marked fall in some crops but that in general responds to the recovery of agricultural productivity after years of drought. A recovery for which now the sector fears. The good news is that they await us a few days, Maybe weeksof thermal relief. The issue now is whether it is down the temperatures and rainfall that is expected these days are able to relieve this situation. In Xataka | We thought we were facing a “historical” oil harvest.

will pause its AI during heat waves to relieve the electricity grid

by

Google has announced A pioneering agreement with two of the main electrical companies in the United States to reduce the consumption of their data centers during energy demand peaks. In other words, Google will pause its artificial intelligence during heat waves. AI is hungry. It is no secret that generative artificial intelligence has a voracious energy appetite. Train and execute the huge models that drive from the summaries in the Google search engine to the youtube folded videos requires dozens or hundreds of megawatts of power continuously. This massive consumption, concentrated in huge data centers, has become a growing concern for electricity companies, which see how energy demand triggers at a rate that the current infrastructure is not prepared to support. An unthinkable movement. Until now, the main concern was to add enough power to the network, with solutions that go From reopening abandoned nuclear centers until Sign the largest hydroelectric agreement in history. But Google’s last movement proposes an unthinkable solution in the competitive AI industry: instead of just increasing energy supply, managing demand flexibly. The measure, agreed with two of the main electrical companies in the United States (TVA and I & M.), arrives just when both states prepare for an intense heat wave. While millions of homes and companies light their air conditioners, putting the electricity to the limitGoogle has agreed to reduce the consumption of its less urgent tasks to avoid overloads and possible blackouts. Demand flexibility. Google has not invented anything new. This type of Flexible response to network demand It already applies in many industries, usually to pay a lower price for the light. Google itself has used it for a long time to postpone non -essential tasks, such as the processing of YouTube videos, moving them to data centers in other time regions or executing them at night, when the demand for the network is lower. The novelty is that, for the first time, it will apply contractual to automatic learning workloads, the heart of the AI. According to the agreement, if the demand for energy increases dangerously or there is an interruption in the network due to extreme weather conditions, operators can ask Google to reduce their consumption. Google will respond by reprogramming or limiting non -urgent tasks until the network stabilizes. You won’t run out of Google Maps. The company has made it clear that this demand response system has its limits. Critical services that require 100% reliability and constant availability, such as the search engine, Google Maps or cloud services for clients of essential sectors such as health, will not be affected. Flexibility will apply to tasks such as the training of new AI models thanks to advances in techniques such as Checkpointing (which allows you to save the progress of training and resume it later). A model could be trained exclusively at night, when the network capacity is greater, without losing the work already done. What does Google win with this? In addition to relieving the overload of the network and preventing off, the clients of the network will end up reducing the light of the light thanks to this system. Including Google data centers.

After the earthquake of Russia, evacuations and alerts extend through the Pacific for fear of something much worse: waves

by

With the still recent memory of what happened in March 2011, when a Powerful earthquake Registered in front of the Japanese coasts, it generated a tsunami and sowed the destruction, with thousands of victims and missing, in Japan and Russia they look at the ocean with tension. And they are not the only ones. The reason: Another powerful earthquakeof magnitude 8.8, has shaken the ground of the Kamchatka Kraiat the east end of Russia, and unleashed the fear for the waves it can generate in the Pacific. In just a few hours that has resulted in alert messages, evacuations and authorities asking the population to stay away from the coasts. What happened? That the ground has trembled in Russia. And with violence. In the last hours the US Geological Service registered an earthquake from Magnitude 8.8 at the east end of Russia. More specifically the tremor broke out At 23.25 h GMT (two more in peninsular Spain), with epicenter 126 kilometers southeast of Petropavlovsk-Kamchatskyin the Kamchatka Krai, in the north of the Pacific, and a depth of around 19.3 km. In some areas of the region they soon registered waves between three and four meters high. Has it been serious? Sergei Lebedev, the head of the emergency department in the region, He explained That the earthquake has left some injured, although for now, as confirmed to the Russian agency Tass, there seems to be none of gravity. It is not bad balance if the power of the earthquake is taken into account, of magnitude 8.8. The governor of Kamchatka has recognized that the earthquake was “serious” and “the strongest in decades”, which explains that the tremor causes the collapse of part of the facade of a nursery. “Before July 31, a list of buildings will be developed that will undergo instrumental inspection. The general evaluation of material damage will be ready in a week,” Point out The governor of the region, Vladimir Solodov. In its telegram channel, the Unified Geophysical Service of Russia has confirmed that it is the greatest earthquake since 1952 in Kamchatka (in November of that year there was another tremor of Magnitude 9 which generated important material damage and caused waves of several meters in Hawaii) and the sixth most intense globally since 1900. What reactions has generated? Fear. And caution. Since the earthquake was produced by authorities from different countries and regions bathed by the Pacific, from Russia to Chile or the United States, passing through Japan or the Philippines, have reacted with different degrees of alert, depending on the type of waves they expect. One of the most forceful responses has probably given Japan, where alert sirens have already been heard and seen to the Hokkaido coast residents Uploaded to roofs When the initial waves of the Tsunami, 30 centimeters arrived. The authorities have ordered the evacuation of the east coast of the country, punished in 2011, and required more than 900,000 people of 133 municipalities of the Pacific coast that leave their homes. Some sources They raise the population that has received evacuation orders or alerts to about two million. Have you done anything else? Yes. On the island of Hokkaido, an evacuation order of 5 out of 5the highest level, which affects about 10,500 citizens of the town of Urakawa, and the alert has spread to prefectures such as Hokkaido, Aomori, Iwate, Mie or Miyagi, among others. In some regions waves of up to three meters are expected. With that backdrop, public transport has been altered at some points and the authorities They have evacuated to the workers of the Fukushima nuclear plant, which was already affected by the tsamot of 2011. And beyond Japan? Russia and Japan are not the only ones who have activated emergency measure. The United States Tsunamis Alert Center has warned of the risk of waves of more than three meters in the Hawaii archipelago and between one and three on the island of Guam. Before Panorama the governor of Hawaii, Josh Green, has declared The state of emergency and ordered evacuations in areas of the coast, which has even derived in traffic jams. In the islands they have also enabled shelters in schools, hotels or community centers. It is not the only American territory that looks at the Pacific. The National Office of Oceanic and Atmospheric Administration (NOAA) has also transferred the alert to some parts of Alaska and follows the situation on the east coast of the country, such as California. “Keep strong already except!” I exhort Donald Trump. Are there more countries on alert? Yes. In Chile President Gabriel Boric He has recognized That, “for now, we have Tsunami alert for the entire coast” on Wednesday. “The protocol is to evacuate three hours before the estimation of arrival of the wave,” he said. In China the tsunamis alert center He has warned also of the possibility of receiving waves of between 30 and 40 cm in Zhejiang and Shanghai and Peru has activated Also alert in his coast. Ecuador has even gone further to order the eviction of the Galapagos Islands, “which implies the suspension of maritime activities and eviction of beaches, docks and low areas.” The list adds and continues with organisms from different nations that ask for caution in different points of the Pacific. In Mexico the Semar has issued an alert For the country’s coast bathed by that ocean after the Kamchatka earthquake and has asked its population to remain away from the beaches and warn of strong currents.

Jordi Wild has the most controversial podcast in Spain. And precisely that is what waves have rewarded

by

Jordi Wild, one of the undisputed stars of the podcastfera in Spanish, has won a wave In recognition of his career. Of course, Wild is not the first successful podcaster, born completely in the Internet sphere, self -produced outside the radio tradition, which wins the prize. But it is the first that has taken as references to iconic Anglo -Saxon names of the environment and has adapted them to its own style and very well, controversies included. Therefore, that waves is more than recognition of unquestionable success: it is also corroboration by the STABLISHMENT of the radio of one of the most peculiar personalities of the environment. Jordi Wild’s meteoric ascent. The YouTuber and Podcasts created its YouTube channel ‘in 2013The Rincón de Giorgio‘, which initially focused on a derivative and usual content by the time: gameplaysreaction and parodies videos. Soon he began to enter other issues, such as current debates and issues related to criminal psychology. In 2020 He started his podcast ‘The Wild Project‘. Although it is a bit complicated to calibrate its reach, On YouTube It approaches the 7 million subscribers, more almost 90,000 in podimo. His possible millions of listeners make him one of the most influential and followed podcasts in Spanish. Joe Rogan’s shadow. Jordi Wild has several times that One of its greatest influences To create and develop The Wild Project is Joe Rogan and his podcast ‘The Joe Rogan Experience‘. It was he who inspired him in the search for a format of long, deep interviews and without censorshipwhere the guest is the protagonist and all kinds of topics are addressed, not necessarily linked to its knowledge area. Other influences that Wild has cited in its programs, notoriously always American, are Howard Stern, David Letterman or Johnny Carson, of which he values his ability to face all kinds of guests. Podcasts in the waves. Since 2016 the podcasts have a presence in the waves, the awards to the media, programs and those responsible that since 1954 delivers the SER. That year The award for the best program, radio or radio online broadcast platform was given to Podium Podcast (hurry owned). Since then, programs such as ‘Xrey’, ‘Weekly deform’, ‘stretching the gum’, ‘Titania’ or ‘La Ruina’ this year have been awarded. But in addition, podcasts began to be specifically rewarded in Podcast Global Wave Wave Awards From 2022, an initiative in collaboration with Spotify to recognize and give visibility to the podcast industry in Spanish. The first delivery gala was held in May 2022 in Malaga. It is in this context that Jordi Wild has received a Special Recognition Prize for his career. Opening of sights. In this way, the waves open the door to a completely Anglo -Saxon style of influence, without equivalents in Spain at the level of success and scope, and that distances themselves from the winners so far, which enter into fields (audioficctions, humor and conversational, sound trials) that have always been present on the radio. The in -depth and uncensored interview style that Wild represents is Pure Podcasta land where There are no time limits and the programs They do not have thematic clippers and of format that does have traditional radio. The bleaching of Giorgio. But Jordi Wild’s program is not devoid of controversy, and has received abundant criticism, especially for the freedom of expression he presumes, and that has earned him criticism of both conservative and progressive sectors. He has been accused of giving voice to characters of controversial ideologies, which has generated debates about whether your whitish space extreme right speeches or spread Fake News under the appearance of open debate. Wild has always defended his decision to invite people of all ideologies and reject any attempt of external censorship or pressure. Some of his guests have given him controversies who have had a deep impact on his image, as was the Presence of former Villarejo Commissioner or the recent presence of A lifeguard Tiktoker which presumed to attract bathers to dangerous areas to get the hero. What waves wants. And this controversial image is the one that waves have rewarded, because it is what is most distant from the traditional radio. The search for the cut that is viralized in networks is what distance to programs such as The Wild Project of traditional radio, and it is what makes this prize especially relevant: the waves give visibility to a typology of podcast that until now had not had official recognition for being especially controversial and controversial. Podcast awards. In general, the prizes of the mainstream (In any field of creation) to their representatives less pigeonholed by traditional formats they usually reach the wrong (that’s why Jordi Wild receives an award for his career: he has been working for years: his style has been working for years). But they are always a sign that something moves within the traditional mass media: we cannot expect them to recognize the avant -garde, but it is still a warning that at least they are looking in the same direction as the public and the creators who carry the lead.

Spain promised them very happy as the power of the data centers. Did not have the heat waves

by

On July 19, 2002, at 06:33 PST, Google and Oracle Data Centers in London They stopped working. The reason was not a human or electrical failure. The only thing that happened is that 40 ° C were exceeded in the British capital, and the cooling systems of that data center could not support those temperatures. The result: falls of multiple services for hours. It was a dangerous advance (and we are talking about London, which is not especially hot) for data centers, especially considering what comes to us. Climate change also threatens data centers. The only good news of this summer’s extreme heat is that It will be carried compared to the one in the coming years. The theme, which is worrisome to humans, has a surprise derivative: these extreme temperatures are going to be a colossal challenge for data centers. We do not stop seeing record temperatures one summer after another, and that will test the cooling systems of those centers. Hello, cooling. There are no definitive data on the temperature at which data centers must work, and while certain experts They recommend that work in a range of 18 to 27 ºC, others They hold that the range must be even cooler, between 17 and 21 ºC. And of course, that is only achieved with powerful air and liquid cooling systems. Heat comes out. If it is more hot, it is necessary to refrigerate more, and that imposes greater electrical consumption and therefore, a greater electricity bill. Of not controlling those temperatures the efficiency of the components is decreasing. As in mobile. It is exactly the same thing that happens in our mobiles and computers when they overheat: if the cooling systems fail to bother those temperatures, The ‘throttling’ is normally produced: The components “go round” to consume less and dissipate less heat. And the water, too. In many data centers liquid cooling also plays a fundamental role, and in the face of heat waves, water consumption also rises. That is especially worrying now that Big Tech have announced that they will invest tens of billions of dollars in new data centers for AI. Liquid cooling to power. In those facilities dedicated to AI a huge amount of chips accumulates in small spaces, which makes liquid cooling solutions much more appropriate. And the same thing happens again: before extreme temperatures, it is up to “climb the cooling systems to deal with possible overheating. Evaporative cooling. Of course, engineers who develop these types of projects go to solutions to try to avoid problems, especially when data centers are in areas where summers are especially extreme. There come techniques coom the Direct evaporative coolingin which the refrigerated and humidified air is directly entered the data center. There are other techniques such as water cooling towers and of course an intelligent management of air flow management is optimal. Be careful where you look up your data center. That makes it more and more important to choose the ideal location for new data centers. In Spain Aragon is becoming In an absolutely protagonist region. There are several projects in which Big Tech will put (theoretically) in progress data centers in this autonomous community, although the risk of extreme temperatures there is not so high as would be further south of the peninsula. But with increasingly high temperatures in summer, what can be done? Ice cream clusters. The option in some cases is simply to choose locations in which the weather is much cooler … or even icy. Facebook has already built several Data centers in Lulea (Sweden) In 2013, but in Spain we have an even more striking case: the Social Security CPD He moved from Madrid to Soria for the simple reason that it is colder there. That, among other things, allowed to save The 150,000 euros that would have cost the cooling of these systems in Madrid during the summer.

The explanation is Rossby’s waves

by

The extreme heat has undoubtedly been the defining feature of last June. However, between warm episode and warm episode, we have seen the passage of troughs that brought us some thermal relief, accompanied, yes, storms and even hails. Right now we are in full of relief, next week, the situation seems uncertain. Cold air, hot air.Meteorologists expect the beginning of the week that is standing out for an abrupt contrast between the north and center and south of the peninsula. The reason is in the presence of two differentiated air masses, a cold to the north and one of warm air to the south. Rossby’s waves. To explain what happens at the atmospheric level, it is convenient to detail before one of the phenomena involved, the not well -known Rossby waves. What exactly are these waves? It’s about Atmospheric waves of planetary scale that mark the alternation of trough and dorsal in middle latitudes, such as ours. These waves move west to this dragged by the meanders of the polar jet. In principle, waves are governed by a kind of balance, what meteorology calls compensatory behaviors: if the pressure decreases in some area, in another it must fall. “Strange dynamics ”. The problem is that we are entering unknown territory. As recently explained the physicist, disseminator and researcher JJ German Through your account in Twitterthis should imply, that as time passes, conditions such as those lived in the month of June should be “compensated” with more or less opposite conditions in the coming weeks. But there is a problem and we are in unknown territory. “As this year we have, indeed, a strange dynamic, just this will not happen: a trough with the opportunity to” sweep “the Iberian Peninsula … and it is only going to touch the north and northeast. The rest almost nor does it find out,” It points to German. That is, everything seems to indicate that after the succession of hot episodes marked by the extreme anticyclonic time, the “calm” of the troughs will not arrive or, at least, it will not arrive with the intensity that you would expect. What can we expect? The story seems to be repeated, more or less. The troughs that are now giving us a breath of heat will last little and next week the heat will return. Although not quite: during the first days of the week a mass of warm air will settle on the center and south of the peninsula while a mass of cold air will remain in the north. Meanwhile, the situation will not be far from what we have seen at other times of transition, in which the heat will coexist with the appearance of storms. The State Meteorology Agency has activated various notices today and tomorrow, both for rains and storms and by maximum temperatures. In some areas of the northwest we can see even areas where notices by maximum temperatures will share space with storms or rainy warnings. From Sunday the expected notices are only because of the high temperatures.
