Two gigantic submarine cables between Spain and Italy, among the large European electrical interconnection projects

by

The European Union is immersed in a full energy transformation at two levels: the transition towards renewable sources and a structural change deep, so that success depends less on each country’s individual generation and more on the ability to move that energy efficiently across borders. In this framework, the European Network of Electricity Transmission Network Operators (ENTSO-E) works on a continental grid that eliminates technical bottlenecks. An example: the energy island called the Iberian Peninsula. The objective is for energy to flow from areas with surplus to others with deficit, preventing it from being trapped without a commercial outlet due to lack of transportation capacity. With that logic, the ENTSO-E just published its complete portfolio of the Ten-Year Network Development Plan 2026 with almost 200 transmission projects, 22 of them completely new. Among these novelties there are two particularly important for the Iberian Peninsula: they connect Spain with Italy. The cables. Apollo Link and Iberia Link are two high-voltage direct current submarine cable projects that would cross the Mediterranean to connect the Iberian Peninsula with northern Italy. They are independent of each other but share the same mission: to create a direct electric highway between an area with great renewable generation capacity such as Spain and one of the industrial regions with the highest electricity consumption in Europe, northern Italy. None of the projects has support from the transport network operators of each state, Red Eléctrica and Terna, respectively, but rather They are initiatives of private investors of Italian origin whose identity has not been revealed. Why is it important. The emerging continental grid is vital for the decarbonization of the continent as it allows the full use of renewable energy surpluses: Spain is one of the leaders in solar and wind energy (Italy stands out in solar, but not so much in wind) and this interconnection makes it possible that when there is excess production in the Iberian Peninsula, that clean energy can supply Italian demand instead of being left without a commercial outlet due to lack of transport capacity. The foreseeable net flow would be predominantly from west to east, although the connection would also allow energy to be imported from Italy in times of shortage on the Peninsula. But for the Iberian Peninsula it is even more relevant: this future east-west corridor allows its surpluses to be evacuated to the rest of Europe, thus ending its limited interconnection capacity. And also something essential: this connection provides security of supply (as evidenced the blackout) and the possibility of coupling markets to reduce electricity prices for the final consumer. Context. The Iberian Peninsula is considered an energy island within Europe. Its interconnection capacity with France round 3,000 MW, far below of the 15% target of installed capacity established by European regulations. And this has consequences: in times of high renewable generation, prices become negative within the peninsula and surplus energy cannot be exported. In times of scarcity, it cannot be easily imported either. This is just one of the projects that seek to end the energy isolation of the peninsula: they are also on the table the Bay of Biscay submarine cable planned for 2028 and included in all PCI lists since 2013. And under construction is a new northern interconnection of Portugal with Galicia which will add an extra 1,000 MW of exchange capacity. On the other hand, the trans-Pyrenean projects in Navarra and Aragon they are still blocked and with no date on the horizon to unclog them. Retail. Some technical curiosities of both cables: Apollo Link is the more ambitious of the two. It consists of an interconnection between Spain and northern Italy with a capacity of 2 GW planned to enter service in 2032. It would implement the most modern standard for long-distance underwater transmission for bidirectional control and minimize losses, bipolar HVDC technology with VSC converters. It would operate with the standard adopted by the European industry of 525 kV, facilitating interoperability. Its capacity allows it to supply several million homes. According to its promoters, it would generate more than 300 million euros annually in net social benefits. Iberia Link shares the same technology and operating voltage, but has a lower capacity: 1.2 GW. What distinguishes it is its length: 1,034 kilometers of submarine cable between southern Spain and northern Italy, which would make it one of the longest underwater electrical links in the world. It has no published entry into service date. Specifications of both cables. TYNDP map Yes, but. That they are included in the TYNDP 2026 is the prerequisite to qualify for the status of Project of Common Interest that opens the doors to community financing and an accelerated regulatory framework, but for the moment the situation of both is “under consideration”, which means that they are in the study phase and do not yet have European regulatory approval: they will have to pass the cost-benefit analyzes of the ENTSO-E to take the first step to materialize (we will know in the last quarter of 2026). And furthermore, they do not have the support of state operators, nor permits or approved layout because they are in preliminary phases. Likewise, the history of blocking similar projects invites caution. But even if they became a reality, these projects would only partially mitigate the electrical isolation of the peninsula: they are only 3.2GW of the 10-15GW of total interconnection necessary to truly influence the European market.

A company wants to sell sunlight on demand using gigantic mirrors in space. We have questions

by

A Californian startup wants to sell solar light at night and, although it has not yet started, many scientists are already putting their hands together. They find it difficult to do it correctly for technical reasons, but they consider that it would be even more serious if these difficulties are resolved. The consequences for people’s health, the environment and the work of astronomers can be devastating. The longest day. The goal of Reflect Orbital is to launch into space a swarm of 4,000 satellites loaded with giant mirrors. These would capture sunlight from the illuminated side of the Earth and reflect it in dark areas. Thus, the solar panels could work 24 hours a day, not only when sunlight naturally falls on them. First steps. For now, the objectives of this startup have been developed only on paper. They already have their first satellite ready, which they have named Eärendil-1, in honor of a JRR Tolkien character. However, They are still waiting for the Federal Communications Commission (FCC) to of the United States gives the green light for its launch. In principle It is scheduled to take place throughout this month of Aprilbut there is no definitive date. Once in low Earth orbit, this satellite will deploy an 18-meter-wide mirror, which would be capable of illuminating a 5-kilometer patch on Earth. If all goes well, a swarm of 4,000 mirrors could be launched by 2030. The background is not good. There was already a project similar to this developed in Russia in the 1990s. The goal of the project, named Znamya, was to illuminate Siberia in the dark winter months. And they got it. However, the resulting light was so dim and the satellite so difficult to control that the mission was never completed. More than technical difficulties. Fionagh Thomson, researcher in spatial ethics at Durham University, explained in statements to Live Science who does not believe that the project is viable today, since the engineering involved is very complex. They already verified it in Russia. But that’s not all. Both this and other experts warn that a large amount of light pollution would be generated, which could affect the circadian rhythms of living beings in the illuminated environment. It could also dazzle aircraft pilots and make the work of astronomers difficult. Even astronomy enthusiasts trying to look at the sky with binoculars or a telescope could suffer vision damage if they encounter the light reflected from these satellites. After all, the population would not be notified before changing the direction of the mirrors. Worse than Starlink. starlink, Elon Musk’s telecommunications companyhas been receiving criticism for many years for the artificial way in which they illuminate the night sky. However, this company’s satellites accidentally illuminate the Earth. In this case it would be something deliberate and, therefore, even more intense and serious. It’s not worth it. All these risks are not worth it when you consider the results. And many other experts assure that the light that would be obtained would be too dim. The solar radiation that would reach the solar panels, for example, would be a minimum fraction of that which arrives during the day. In order to obtain a sufficient amount of light, an exorbitant number of satellites would have to be launched into space and that would be expensive and even more dangerous. Beware of space debris. If the mirror of Eärendil-1 will measure about 18 meters in diameter, the goal of Reflect Orbital is to launch satellites into space with even larger mirrors, up to 54 meters. In general, they would be giant objects; who would therefore be at greater risk of impacting with meteorites or space junk fragments. The more exposed surface, the more risk. This would not only mean the uncontrolled release of fragments resulting from the impact, it would also cause damage to the structure of the mirrors themselves. A leaky mirror would be even more difficult to control and its harmful effects could worsen. Therefore, although the goal of selling sunlight at night seems feasible on paper, in reality it is complicated and dangerous. We’ll see where all this goes.

China has been pushing the boundaries of engineering for years. Its gigantic high-speed tunnel boring machine has just given another example

by

China has been developing large infrastructures and its own machinery to execute them for years, with projects that tend to stand out for their size and the technical control they require. It is not just about building more, but about doing so under increasingly demanding conditions. This pattern is repeated in very different areas, from energy to scientific research, and also in transport infrastructure. Under this logic, the appearance of new machines and projects is not an exception, but rather the continuation of a clear trend that now adds a new chapter with the “Linghang” tunnel boring machine. The advance. “Linghang” has completed the section under the Yangtze Riverwith a continuous excavation of just over 11 kilometers, according to CCTV. The machine began its journey on April 29, 2024 from Chongming Island, in Shanghai, and after 23 months of work, it completed the underwater section of the river, surpassed the south dam and came ashore in Taicang, in Jiangsu province. The movement is not minor: it involves completing the section under the watercourse, one of the key points of the work, and leaving the project one step away from its next milestone. What’s behind. The operation is integrated into the tunnel Chongming-Taicanga key work within the Shanghai-Nanjing section of the Shanghai-Chongqing-Chengdu high-speed corridor. With a total length of 14.25 kilometers, this infrastructure brings together several technical milestones, including the world’s longest single head excavation distance in a high-speed tunnel, with 11.32 kilometers, and a maximum depth of 89 meters under the Yangtze. The design contemplates the passage of trains at 350 km/h even in the underground section. The machine inside. The tunnel boring machine used in this project has unusual dimensions even within this type of work: it measures about 148 meters in length and weighs around 4,000 tons. according to Global Times. It is equipped with an intelligent control system called I-TBM, designed to automatically manage a large part of the excavation process, from internal pressure to the forward position or the exit of the material. Added to this are elements such as high-pressure seals, a long-lasting main bearing and a cutting head prepared to withstand demanding conditions under the river. A project that is not an isolated case. In recent years, the country has built facilities such as the Three Gorges Dam, the FAST telescope either the EAST reactorprojects that, although they belong to different areas, share the same base: scale, technical control and own development. In this context, this type of machinery is best understood not as a specific milestone, but as one more piece within a sustained line of work. A close reference. In Spain, the Mayrit tunnel boring machine, currently in use in the expansion of line 11 of the Madrid Metrooffers a useful point of comparison to understand the magnitude of this type of machinery. Measuring about 98 meters in length, weighing around 1,500 tons and with a diameter close to 9 meters, it is a large piece of equipment within the European context.

It should be impossible for an iPhone 17 Pro to run a gigantic 400B AI model. Ought

by

The iPhone 17 Pro has 12 GB of unified memory. It is a very decent figure for a mobile phone, but in theory absolutely insufficient to run large AI models locally. And therein lies the surprise: a new project has made it possible for this mobile phone to run locally a model with 400,000 million parameters (400B). And that opens the doors to a promising horizon. Giant AI model, dwarf memory. A developer named Daniel Woods (@dandeveloper) has created, thanks to AI, a new inference engine called Flash-MoE whose code has been published as Open Source on GitHub accompanied by a study about his behavior. woods managed to run locally the Qwen 3.5 397B model (the full version, without distillation or quantization) on your MacBook Pro with 48 GB of RAM. Downloaded the model (209 GB on disk) and developed that inference engine to achieve something that seemed almost impossible. Other developers have gone even further and have managed to run models like DeepSeek-V3 (671B) or even Kimi K2.5 (1.026B!!) on their MacBooks. The speed is slow, no doubt, but they work, they work. It’s amazing. iPhone 17 Pro is capable of running a 400B model. Another developer called Anemll wanted to go a little further and try to run this model with almost 400,000 million parameters on his iPhone 17 Pro with 12 GB of RAM… and he succeeded. It is true that the model is very slow in responses (0.6 tokens per second, very unusable), but achieving something like this opens the doors to a future in which video or unified memory is no longer so critical to be able to use huge AI models locally. a few hours ago doubled the speed at 1.1 tokens per second, reducing the number of experts to four (2.5% quality loss in responses). It is still not entirely usable, but the technical demonstration is evident. Another user has preferred to use a somewhat smaller model (Qwen 3.5 35B) but still huge for the iPhone, and has already managed to get it to run locally at about more than acceptable 13.1 tokens per second. Why it matters. The AI ​​models we use in the cloud (ChatGPT, Gemini, Claude) are gigantic and run in data centers with thousands of chips and enormous amounts of memory and storage. They are the most powerful because they run on the most powerful machines. Although it is possible to use AI models locally, the models that we can run are much smaller and that makes it difficult for them to behave equally well both in quality of responses and in their speed or precision. This method opens the door to a future in which even on “modest” machines it is possible to run giant AI models that give better answers and allow us to avoid using models in the cloud. Apple already warned. Three years ago a group of Apple researchers published the study ‘LLM in a flash‘ which precisely pointed to that: to run AI models locally it would be possible not only to take advantage of the unified memory of Macs, but also their storage units. The speed would be slow, yes, but this would open up the possibility of running gigantic models locally on machines with much smaller amounts of unified memory. Woods used Claude Code with Claude Opus 4.6 and applied the new methodology “autoresearch” by Andrej Karpathy to implement Flash-MoE based on that research. The result is really promising. Video memory was everything. On my Mac mini M4, for example, I have 16 GB of unified memory. This means that with tools like Ollama you can install and run models like Qwen 3.5 4B locally with some fluidity, but 7B models or others like gpt-oss 20B would be much slower in responding (or would get stuck altogether). Video memory (or unified on Apple devices) is the most important parameter when running local models, both in terms of quantity and bandwidth. If you want to use them fluidly, that’s the limiting factor. It is possible to use “regular” RAM, but the speeds when using it are reduced so drastically that it is often better not to use that option at all. If you have a fast SSD, you have a treasure. Now the limiting factor is our SSD drive, since the model uses it as if it were a kind of substitute for video memory. And the faster the SSD drive on our computer, the better. There is good news here, because lately we are seeing how PCIe 5.0 drives they achieve about 15 GB/s without too many problems, and that speed already gives enough room for maneuver to use much larger AI models locally than we could use before. A promising future for local (and more private) AI. This discovery is really striking for everyone who wants to use AI locally, because it allows you to use huge models without having to make a huge investment in the latest generation graphics cards or, for example, in a Mac with a lot of unified memory: a Mac Studio M3 Ultra with 512 GB of memory, for example, costs more than 10,000 euros. With this new method we could opt for a much cheaper machine that, with a good SSD unit, would allow us to use giant models in a fairly decent way. Not as fast as those other options, sure, but still very decent. It’s a notable step forward in enjoying the benefits of running local AI models, including the biggest of them all: privacy. With this type of local execution, our conversations and everything we tell the chatbot stays on our machine, it does not end up on the servers of companies like Google, OpenAI, Meta or Anthropic.

Tehran has a gigantic “Plan B”

by

“A single shot at one of our men or ships, and he would make a good deal of Kharg Island. He would come in and take it.” The phrase could have been written this morning on the social network Truth Social, but it is almost forty years old. American President Donald Trump was already fantasizing in 1988, during an interview with Guardianwith taking over the main Iranian oil terminal. Today, four decades later and in the midst of the Third Gulf War, that old script has jumped from the paper to the Pentagon crisis room. For influential figures in Washington, such as Republican Senator Lindsey Graham, the equation is simple: He who controls Kharg, controls the fate of the war. The prevailing idea is that this island of just 20 square kilometers functions as an “off button” for the ayatollah regime. However, this one-dimensional vision collides head-on with a much more complex reality. Washington believes that taking this terminal will subdue Tehran, but they have forgotten that the Islamic Republic has been building a gigantic “Plan B” for years to survive precisely this scenario. Kharg: the untouchable heart. To understand America’s obsession, you have to look at the numbers. Kharg Island is the true economic heart of Iran. Located about 25 kilometers from the coast in the Persian Gulf, its deep waters allow supertankers to dock that the continental coast cannot accommodate. He usually travels there 90% of the country’s crude oil exportsgenerating annual revenues of $78 billion that directly finance the Iranian military. Even though the war began in late February 2026 and the United States and Israel have bombed thousands of targets, the island’s oil infrastructure remains strangely intact, and the reason is economic. Analysts at JP Morgan and Chatham House They warn that destroying Kharg It would cause an earthquake in global markets, shooting up the price of a barrel to $150. “Plan B”. This is where the American strategy breaks down, just as Javier Blas explainsenergy columnist Bloomberg. The idea that capturing Kharg will subdue Tehran is, in Blas’s words, “fanciful.” Iran does not depend on a single faucet. If Kharg falls or is blocked, the regime would immediately activate its network of secondary terminals: Jask: It is the strategic jewel of “Plan B”. Located in the Arabian Sea, it allows Iran to export oil, completely bypassing the disputed Strait of Hormuz. According to Blas, it could pump about 300,000 barrels per day. Lavan, Sirri and Qeshm: These three islands within the Persian Gulf have a combined capacity of another 200,000 to 300,000 barrels per day. The treasure of derivatives: Iran does not only live off crude oil. It exports another million barrels per day of natural gas liquids (NGL) and refined products (naphtha, liquefied gas) from terminals such as Assaluyeh, Bandar Mahshahr and Abadan. It is their second most lucrative source of income. As Javier Blas explains, To truly choke off the flow of petrodollars, Trump would have to not only take Kharg, but capture all of these terminals simultaneously. Otherwise, a constant flow of barrels would continue to sustain the Iranian war effort. Besides, as I already explained in Xatakathe war has not sunk the Iranian oil business, it has accelerated it. The failed ultimatum: a step back from Trump? Washington’s strategy until now was shifting from bombing to occupation. As my colleague Miguel Jorge has detailedthe Pentagon is accelerating the deployment of the USS Boxer amphibious group and thousands of Marines to the region. The objective would be to take physical control of the island to use it as a negotiating lever and force the reopening of the Strait of Hormuz, which Iran maintains blocked. In fact, as you have had access AP NewsTrump gave Iran 48 hours to open the strait under threat of “wiping its power plants off the map.” However, hours before the deadline expired, the president backed down. through your Truth Social account: “I am pleased to report that the United States, and the country of Iran, have had, over the past two days, good and productive talks (…) I have instructed the War Department to postpone any and all military attacks against Iranian power plants and energy infrastructure for a period of five days, subject to the success of the ongoing meetings.” Iranian state media, for its part, They quickly denied any direct negotiations and stated that the American president “withdrew for fear of Iran’s response.” The threat of regional destruction. Added to this is the doctrine of “mutual assured destruction” at the regional level. If Trump attacks Iran’s energy infrastructure or takes Kharg, Tehran has vowed to respond with fire. According to AP NewsIran’s Defense Council has threatened to mine the entire Persian Gulf (“like in the 1980s,” they warned) and bomb power and desalination plants in Arab countries allied to the United States, including the Barakah nuclear plant in the United Arab Emirates. Finally, recent history works against the White House. Javier Blas remember that during the campaign of Trump’s “maximum pressure” between 2020 and 2022, Iranian crude oil exports fell by 90%, below 250,000 barrels per day for months. Despite extreme financial pain, the regime did not collapse. To think that they will give in today, when they started from a record production of almost 5 million barrels of liquid petroleum per day (the highest in 46 years), is to ignore the lessons of the past. Washington’s miscalculation. Donald Trump’s fixation on Kharg Island belongs to an era when brute American force rarely met with asymmetrical resistance. Occupying this tiny patch of land in the Persian Gulf may seem like the perfect coup d’état to force a quick outcome, but the reality on the ground is stubborn. By focusing its sights on a single objective, Washington underestimates the resilience of a regime that has been preparing for economic and military isolation for decades. If the Marines manage to plant their flag in Kharg, they will discover that they have not shut down the Iranian … Read more

gigantic boards that monitor war conflicts

by

This Saturday, February 28, Israel, with the help of the United States, began a bombing of Iran. Beyond the news, one of the current obsessions is to be informed in real time about the conflict. And this is where the vibe coding You have shown your best face again. Developers are creating online platforms to follow war conflicts in real time with a level of detail that, to date, was not possible with traditional websites. The obsession with conflict. The war has become a board. One that we not only want to be informed about, we want to monitor it in direct time due to its direct implications worldwide. This is where maps, alerts, and interfaces that “gamify” the information experience gain interest. And in recent times the vibe coding has made it clear. The great war board. The obsession with knowing every detail of the global conflict has led developers to create tools such as World-Monitor. Giant information panels in which the conflict can be followed in real time, through each and every one of the necessary pillars: A global map with alert level legend live cameras Live broadcasts from media such as Bloomberg, CNBC, Euronews Adjustment layers to focus attack zone, military bases, submarine cables, data centers, military activity, ship tourism, trade routes Analysis of country instability, overview of strategic risks Independent feed for each area, news, theme Gamifying tragedy. The case of World-Monitor is not isolated, alternatives such as Situation Deck make it clear that this type of panels situation room They want to offer a gamified experience. A visual experience that is more reminiscent of a tactical command center than a traditional medium. Beyond the moral debate, the work of developers vibecoding desktop solutions that offer a much more refined and updated vision than that of many media. Developers are building tools that, in many cases, are faster and more comprehensive than traditional coverage.

Mexico has a gigantic energy treasure under its feet. The plan to extract it is called fracking

by

Mexico is walking on a treasure and, at the same time, on a political minefield. Under the land of states like Coahuila, Tamaulipas and Veracruz, an energy giant sleeps: the sixth world reserves of unconventional gas. Waking him up was the great taboo of López Obrador’s six-year term, a red line drawn with the promise of “no to fracking“However, reality has knocked on the door of the National Palace. In a turn that redefines the new mandate, President Claudia Sheinbaum has faced an iron dilemma: staying true to the campaign promise of not using hydraulic fracturing or pursuing “energy sovereignty”, one of the almost mythical aspirations of the Mexican left, to stop depending on US gas. The president has already made a decision: she is willing to pay the political cost. What began as a rumor has become a budgetary and contractual reality in 2026. The data is compelling and leaves no room for doubt about the change in course. Petróleos Mexicanos (Pemex) has increased its investment for this year in the “Gulf Tertiary Oil” program by 66%, going from 2,423 million pesos in 2025 to 4,016 million pesos in 2026, according to Treasury data obtained via transparency collected by The Universal. The machinery is already in motion. Pemex’s Strategic Plan (2025-2035) schedules the start of these operations after last year’s pilots. Pemex has awarded the first “mixed contracts” to private companies such as C5M, Geolis, CESIGSA and Petrolera Miahuapan. Although the state company retains the majority shareholding and control, it is the private parties who will provide the capital and technology, an urgent need for an oil company with a debt of more than 100 billion dollars. However, this injection of capital has raised alarm bells due to its opacity. The Mexican Alliance against Fracking denounces that in the 2026 Budget there are more than 245,000 million pesos allocated to gas projects that involve hydraulic fracturing, hidden under items that lack public breakdown and transparency, just as collected The Impartial. The semantics of dissimulation If he fracking was a “cursed word” in the previous six-year term, the new government has found a creative solution: change the dictionary. To avoid the political cost of openly announcing the use of fracking, the administration has chosen by a series of technical euphemisms. Rather frackingofficial documents speak of “reservoirs with complex geology” or “reservoir stimulation.” The general director of Pemex, Víctor Rodríguez Padilla, was blunt before the Senate: “We are not going to do frackingwe are taking advantage of technological development in evaluations of existing deposits.” But operational reality belies the rhetoric and breaks the discipline of official discourse. While euphemisms are used in the capital, on the ground urgency rules. The Undersecretary of Hydrocarbons of Tamaulipas, cited by The Countryrecently broke the taboo by declaring: “We talk it like it is here…hydraulic fracturing.” However, to understand the magnitude of the challenge, you have to look at the map. Pemex’s hopes are concentrated in three main basins: Burgos, Tampico-Misantla and Sabinas-Burro Picachos. The Burgos Basin is particularly relevant for being the natural extension towards the south of Eagle Ford in Texas, one of the deposits of shale most prolific of the American boom. If there is wealth north of the border, geology suggests there is wealth to the south as well. However, extracting this oil is not easy. The expert Miriam Grunstein illustrates the technical challenge starkly: the soil in these areas is a clayey “dump” and the crude oil has the density of “toothpaste.” This makes their exploitation extremely difficult, expensive and technologically demanding. Why go back to these complicated areas now? The answer is exhaustion. Pemex is pivoting toward the “unconventional” because its large conventional fields are drying up. It’s a portfolio decision to try to sustain the production platform in the face of the natural decline of traditional fields. If you’re not at the table, you’re on the menu Behind Sheinbaum’s turn is a real geopolitical fear. Mexico imports 70% of the gas it consumes from the United States. “If the United States closes the valve, Mexico will be left in the dark,” recognized the head of Pemex himself. But the scenario is even more complex with the neighbor above led by Donald Trump and his vision of natural resources as national security. Recently, Washington has deployed the Project Vaulta strategy to secure critical minerals and counter China, which includes “geological mapping” of Mexican resources. The pressure is such that the Mexican government has had to give in to the harshest pragmatism. It was the Secretary of Economy, Marcelo Ebrard, who summarized Mexico’s position regarding the US energy integration demands with a lapidary phrase: “If you are not at the table participating, you are on the menu.” Mexico has decided to sit at the table fracking to avoid being devoured. Furthermore, the lack of liquidity forces this opening. Reactivating the identified wells requires immediate investments of more than $1 billion, money that will now come from private partners. The decision has been made, but the results will not be immediate. Although investment skyrockets in 2026, specialists warn that the launch of massive exploitation will take between three and four years to yield tangible results. The government’s optimistic projections suggest that, in their most developed phase, these fields could provide an additional 300,000 barrels per day. To achieve this, the “Mixed Contracts” model will be the norm: Pemex collect immediate bonuses for the award (almost 50 million dollars in the first round alone) and lets the private parties assume the operational and financial risk. A very high price The cost of this decision is already being paid in credibility with the bases. Organizations like Greenpeace and the Mexican Alliance against Fracking They have accused Sheinbaum of “betraying the people who elected her.” The most critical point is water. In a country hit by drought, the National Institute of Ecology and Climate Change (INECC) estimates that 5.7 million liters of water are required per well. Greenpeace raise the alert citing the … Read more

The first hard drives in history were gigantic. Then a miracle happened: miniaturization

by

Nowadays it is normal to have 32 or 64 GB of capacity on our mobile devices, and that capacity is usually multiplied by several orders of magnitude on our PCs and laptops. Storage technology has advanced incredibly in all these years, and to appreciate this evolution it is not a bad idea to take a short trip to the past and see how decades ago hard drives were heavy and cumbersome monstrosities that also had very limited capacity and features. The first example of that evolution we have it in the IBM RAMAC 305a monster that appeared in 1956 and was capable of storing 5 MB thanks to a system with 50 24-inch “platters”. That device rotated at a speed of 600 revolutions per minute and generated such a quantity of heat that it was necessary to enclose it in a large “refrigerator” with two cooling systems. Another curious fact about this product is that IBM already thought about a subscription model to make it profitable: clients who wanted to use this product had to pay $3,200 per month at the time, which would be equivalent to almost $30,000 today with inflation. Miniaturization would still take years to reach an industry that was trying to advance especially in the area of ​​storage capacity: customers demanded more capacity, and those 24 inch plates wereAs seen in the image, huge. In this case these models reached 10 MB capacity per disk. The giant of the time, IBM, dominated the sector for years, and in 1962 the company created the first “removable” drives. The IBM 1311 Disk Storage Drive made use of IBM 1316 “disk packs” that allowed the company’s customers to expand their needs to suit. From the 24 inches of the previous disks it went to 14 inches, with 2 Mbytes for each “pack”. The path to smallness Another of those storage devices It was UniDisc.a storage expansion that appeared in 1962 for the Univac 1004/1005 computers. That “flexible” disk similar to those used by IBM had a diameter of 14 inches and was capable of holding 2 Mbytes of information. The drive the disk was inserted into was about the size of a washing machine. At that time, several manufacturers tried to be leaders in a promising sector, and among them was Burroughs, a mainframe manufacturer that, for example, launched this unit of 250 MB in 1979. A true marvel that used, pay attention, regenerative braking: when it was turned off, the motor became a magnetic brake: otherwise the discs continued spinning for an average of 4 hours. A few years earlier IBM had already launched its new hard drive technology, the so-called “winchester“. The IBM 3340 drive had a smaller, lighter read/write head that had a design that allowed it to move across that surface at a tiny distance. Things would advance from that moment even more rapidly, especially in the field of miniaturization (more or less) and the capacity of units that, for example, in 1980 already reached the gigabyte with the IBM 3380 unit. From that year 1980 is also the Memorex Mark XIV “disk pack” in the header image that was advertised as an “error-free” system. It had a capacity of 80 MB and was intended for Memorex disk drives that were again the size of a washing machine. 5¼ units would soon give way to 3.5-inch oneswhich would arrive first from the Rodime company (with former Burroughs employees, by the way). Their devices were capable of storing 6.38 and 12.75 Mbytes and would start a real trend in the PC and laptop market. User needs continued to dictate smaller formats, and this led to 2.5-inch drives that are currently especially widespread due to their use in the solid state drive segment. The rest, as they say, is history: 3.5-inch drives are still widely used today, but that revolution would be followed a few years ago by that of solid state drives or SSD (especially in M.2 format) that have allowed us to achieve reading and writing speeds that were unthinkable just a decade ago. In the area of ​​capacity and cost per gigabyte, yes, those traditional hard drives continue to be (for now) the kings of the market, but if we want examples of miniaturization, the 1 TB drives that SanDisk presented at CES seven years ago made things even better. And what remains. In Xataka | Sandisk has risen 1,000% in the stock market since the summer.

The US has taken over Venezuela’s oil. The problem is that the package includes a gigantic debt with China

by

The map of world power has been redrawn in just one week. The capture of Nicolás Maduro by US forces is not just a regime change; is the birth of the “Donroe Doctrine”, a movement with which Washington seeks to consolidate an energy empire “from Alaska to Patagonia” to control 40% of world production. However, after the military euphoria in the White House, a dilemma of trillion-dollar proportions looms: the oil has been taken, but it is mortgaged, and China demands its bills. The collector at the door. Control of the largest reserves on the planet has put the US face to face with the great creditor of the Caribbean. According to the South China Morning Post (SCMP)the current exposure in a state of “limbo” is estimated at $10 billion, although other estimates by think tanks collected by the same medium raise the historical debt to more than 60,000 million, much of it structured under the “oil for loans” model. But how was this sum arrived at? China needed energy for its industrial rise and Venezuela needed cash. Under this premise, Beijing financed railways, power plants and more than 600 bilateral agreements. Now, the great fear of the Asian giant is that the new government in Caracas —protected by the Trump administration— invoke the doctrine of “hateful debt”. As Cui Shoujun explains in SCMPthis legal remedy would allow the loans to be repudiated, alleging that China’s money did not benefit the people, but rather financed the survival of the regime. It would be the perfect “legal pretext” to clean up the balance sheets before the American oil companies take the reins. The agony of the Chinese state companies and the shield of the “Teapots”. The anxiety in Beijing is not just political, it is corporate. As revealed by Bloomberggiants such as China National Petroleum Corporation (CNPC) are carrying out damage assessments amid fears that decades of investments will evaporate. Nevertheless, according to information from Reutersthese companies still operate in the country through joint ventures such as Sinovensa, and control rights to reserves amounting to billions of barrels. However, China has an “ace up its sleeve.” A couple of months ago, they were absorbing 90% of measurable crude oil storage. Besides, as detailed by the Financial Timesmuch of the flow of Venezuelan crude oil arrived in China through the “teapots” (independent refineries), which bought the oil at steep discounts to avoid previous sanctions. By taking control of exports, the United States not only recovers crude oil, but also eliminates a key competitive advantage for the Chinese industry, raising its energy costs at a stroke. The technical paradox. Many wonder why Trump would risk so much for oil that seems “bad.” The answer is a necessary technical symbiosisAmerican and Spanish refineries (like Repsol’s) act as “stomachs” designed for heavy crude oil from Venezuela, which needs to be mixed with light oil from the fracking to produce diesel efficiently. However, the prize comes with a bill astronomical repair. The infrastructure is literally in ruins: loading an oil tanker today takes five days compared to the one day that was enough seven years ago, and the crude oil arrives “dirty” (with excess water and salt) due to lack of maintenance. Reconstructing the sector will require 10 billion dollars annually for a decade, to which is added the drama of natural gas: Venezuela today burns in “smoke” the equivalent of the consumption of all of Colombia due to pure technical negligence. The battle of the offices. Trump has taken control of the energy crown jewel, but has found himself with an astronomical repair bill and a Chinese creditor who won’t go away quietly. As the Financial Times warnsif the US decides to also suffocate supplies from Iran after this blow in Venezuela, China could see 20% of its cheap crude oil imports compromised, which would force Beijing into an unpredictable reaction. The real battle did not end with the capture of Maduro; It is just beginning in the offices of Washington and Beijing. Venezuela is the jackpot, but it is a prize that comes with fine print that could go bankrupt the financial balances of half the world. The oil era is not over, but the map of who controls it and who pays for it has been rewritten with blood and debt.

In 1970, a zoologist released a species of rodent into the Caucasus to repopulate it. A century later the destruction is gigantic

by

In the 1970s a story occurred, one of many, where the man tried to modify the ecosystem of an island and it went completely wrong, so much so that It took them half a century to solve it.. However, among the stories with the sending of a “solution” to an enclave as the protagonist, good to annihilate, good for repopulatingfew like the one that occurred 70 years ago in an area of ​​the Caucasus. Unlike the story from Japan, here there is still no way to solve it. Introduction: Soviet ecological ambition. About the 1920s, the Soviet zoologist Nikolai Vereshchagin undertook an ambitious project to “reanimate” and repopulate the fauna of the Caucasus. The idea seemed simple: introduce non-native species. Inspired by the desire to restore ecosystems and provide economic benefits through hunting and the fur trade, Vereshchagin brought animals from different parts of the worldconfident that they would thrive in the mountains and wetlands of Azerbaijan. Apparently, through his investigations and his book “The Mammals of the Caucasus”Vereshchagin documented the constant change in the region and argued in favor of what would become known as “acclimatization”: a species adaptation strategy that sought to enrich local biodiversity, even if over time it proved to have… let’s say, unintended effects. The coypu: from Soviet experiment to invader. And of all Vereshchagin’s most notable experiments, one is written in capital letters with the introduction of the coypualso known as otter or river rat, a species of giant rodent native to South America. Were 213 copies brought to the region, which quickly adapted and thrived in the wetlands of Azerbaijan. Because? Originally, the coypus They were brought for the quality of their skins, used in the making of luxury coats and hats. However, what began as a resource exploitation project soon became an ecological problem. The reason? Coypus demonstrated a high reproductive capacity and adaptability that allowed them to survive and multiply as if there were no tomorrow without the natural predators of their original habitat. This rat is a danger. To give us an idea, currently the coypu is considered one of the 100 most dangerous invasive species worldwide. In Azerbaijan, their populations are ubiquitous in wetlands, causing significant environmental damage by destroying native vegetation and competing with native species for space and resources. Additionally, their presence threatens the habitats of endangered birds, such as the cotton-headed duck and Siberian crane, as both depend on these wetlands for their survival. We are talking about a species whose adults measure approximately 60 cm long and have a 30 cm tail. When fully grown, they weigh as much or more than a Jack Russell terrier. Although they look similar to the capybara (the largest rodent in the world), coypu tend to have fewer “followers.” One fact gives an idea: its most notable feature is its protruding teeth, a pair of long, orange incisors that they never stop growing. Impact on biodiversity. The ecological impact of coypu in Azerbaijan was tremendous over the years, and especially significant due to the natural wealth of the Caucasusa region considered as one of the 25 hotspots of global biodiversity. The creature not only devastated the vegetation in humid areas, but its destructive behavior also affected bird nesting areas. In fact, studies carried out in Italy show that these giant rodents can reach crush nests by resting on themincreasing the risk for local species. Not only that. The species continued to spread to this day, and from the Caucasus it passed to neighboring countries, which has made its management even more complicated. The lack of a detailed study on the size and distribution of their populations in Azerbaijan poses all kinds of additional obstacles for environmentalists, who do not have a solid basis for developing mitigation strategies. Management and reward programs. Today, and in response to the uncontrolled expansion of the species, some experts suggest implementing reward programs for capture, an idea similar to those that have been effective in enclaves of the United States such as Louisiana, where it is offered a payment for each coypu queue delivered. However, others warn that these programs, while temporarily reducing populations, can result in commercial hunts that do not completely eradicate the species. In this regard, the proposal to reestablish a reward system, in force in Soviet times, is viewed favorably by organizations such as WWF Azerbaijan. However, the current system of fees and penalties in the country, which even requires hunters to pay additional payments for “environmental damage,” discourages coypus hunting. Therefore, there is a clear contrast with other countries where the reduction of invasive populations is actively encouraged. Lessons learned and future. Like so many other similar stories with the “hand” of man throughthe story of coypu in Azerbaijan is a reminder of the risks of introducing foreign species without very careful planning and long-term impact assessment. Although no one doubts that the projects of Vereshchagin and his contemporaries were based on good intentions, the collateral effects of their decisions have been tremendous for the region’s biodiversity. Today, environmentalists like Zulfu Farajli told the BBC who advocate for greater public awareness of the impact of coypus on local ecosystems, as well as more effective management policies. Ultimately, the case of this creature in Azerbaijan highlights the importance of developing a conservation approach based on science and sustainability, ensuring that ecosystems can recover and thrive without the threat of invasive species. Hopefully, the solution will never be a giant rat, please. Image | Peter Trimming, Khagani Hasanov1988 In Xataka | Japan sent the wrong creature to eradicate snakes from an island.
