fall

When the heat arrives, the boys fall in love, the solar panels have a fatal and Spain has a new electrical problem

by

Summer has arrived with excessive force To Spain. June has closed as the hottest month of which you have a record, and there is no indications that temperatures are going to give truce. The streets are emptied, public parks are deserted, and fans snort day and night as if trying to mark the rhythm of these unbearable days. But while life adapts as it can to this new heat, under the surface – where the invisible network that sustains modern life – heat has also tested the limits of the electrical system. High demand. While millions of people seek refuge under air conditioning, the Spanish electrical system begins to show saturation signals. Extreme heat triggers demand, reduces the efficiency of some sources of renewable generation and generates imbalances in the electricity grid. As collect the Iberian energy market operator (OMIE)on July 1, the price of the megavatio hour reached a peak of 167 euros at 9:00 p.m., an unusual figure for a night strip. The increase coincides with a high demand and a reduced renewable production at the end of the day, which forces the system to rely on more expensive technologies such as natural gas, According to Red Eléctrica España (REE). More heat, more network pressure. To all this is added an urban phenomenon that aggravates the pressure on the network: The island of heat. In cities, asphalt, concrete and lack of vegetation make the heat accumulated during the day stay overnight, raising the temperature several degrees with respect to rural areas. As a result, energy consumption does not descend after sunset, but is kept high for more hours. The households continue to light fans and air conditioning apparatus until well into the morning, which stress the system when the renewables have already fallen from the mix. But with more sun … The logical thing would be to think that with more sunny hours, Solar energy would suffice to meet the growing demand. And in part, it does: According to REE dataon July 1, renewables contributed 50.6 % of the electricity generated in Spain, compared to 49.4 % of non -renewable sources. But that daily average hides what happens in critical hours. From eight or nine in the afternoon, the photovoltaic disappears from the energy mix, just when the demand remains high and the temperature barely yields. At that time, they are the combined cycles – central that burn natural gas – that support the system, with more than 14,000 megawatts generated in some moments of that same night, According to REE data. There is an added problem. Solar does not always yield as expected: As we have already explainedpanels can have efficiency losses between 10 and 25% because of high temperatures. For each additional degree, they can lose up to 0.5 % yield. Nor does wind help too much: heat waves usually come accompanied by atmospheric stability situations that reduce the wind, which also lasts production. Will there be any blackout? Talking about generalized blackouts may seem exaggerated, but comparison with other countries, like the United Statesforces to take the threat seriously. However, the Spanish system has proven to have a certain margin of maneuver. After the blackout of April 28, they were activated Adjustment services to balance the network in case of collapse of the system at critical times. Although it avoids collapse, these mechanisms have a cost: they have more thanked the invoice part, especially for those in the PVPC rate. From that moment on, Ree has maintained an additional safety margin, operating with active backup power plants even when they are not in use, which structurally increases the operation of the system. Beyond the specific episode, that blackout exposed the deficiencies of a system that needs More storage, MicroRedes and greater local response capacity to disturbances. A system under stress. This summer is not only breaking temperature records: the margins of the electrical system is also testing. The combination of prolonged heat, night demand peaks and a more vulnerable renewable generation than expected is stressing the network at critical moments. The renewables are the present and the future, but they are not infallible. Its behavior also depends on the weather. And when the heat waves become the norm and not the exception, the resilience of the system depends on other factors: on the reinforcement of the networks, the storage, the demand management and, above all, to prepare the cities to resist without the most vulnerable paying the price.

Byd has opened a new price war in China. The fall of your actions confirms that it is a risky play

by

Remove muscle or a sign of weakness. That is what we ask ourselves when we see the last Byd movement in China where the company has applied aggressive discounts to its fleet. The movement has been rejected in the markets but shows that the company has strength to stir the market alone. The discounts. Last May 23, Byd announced a significant reduction in its Chinese fleet. In total, 22 cars received discountsincluding the Byd Seagull, the cheapest electricity in the market and one of the company’s great hits in the country, saw its price another 20%. It is the most striking example of discounts that began in April but have intensified in May. In some cases discounts of up to 34%have been established. A drop in actions. The market response, however, has been clear: a drop of 13% of its actions. It is the figure we have since May 23 were announced the discounts. Investors have seen a sign of weakness or, in any case, greater difficulties in taking out performance from vehicles if prices fall so strongly. And a high sales. 382,476 units. That is the number of units sold by byd last May 2025. It is the highest than we have been for the year and took the electric cars (204,369 units) above the plug -in hybrids (172,561 units), which did not happen since the beginning of 2024, they point out in Bloomberg. The growth of BYD sales comes, without a doubt, promoted by the attractive discounts that the company has put in the last week of May that, remember, add to those of April. In the absence of weekly data, so that we get an idea, Carnewschina Collect the data from May 19 to 25. Those days, Byd put 53,320 units of electric cars on the market. The following manufacturer was Tesla with 10,970 units. So? So, investors seem to be worried, among other things, about profitability. In fact, it is the Chinese association of car manufacturers itself that, without naming any manufacturer, has assured that “disorderly price wars intensify fierce competition, even more compressing corporate benefit margins,” according to Bloomberg. The same medium ensures that regulators have given a touch of attention to the company for fear that unleashing a price war can be carried in front of its competition. He always requested, always according to the American media, “loyal competition” to manufacturers not to generate a monopolistic context. An open war. What is clear is that with discounts, ByD opens a price war With the rest of the companies. At the moment, from Great Wall Motors they have assured that maintaining this path is the confirmation that we can attend the “automotive Evergrande”, in words collected by CNEVPOST. Although, again, no concrete names were given, the association points directly to Byd that is one of the manufacturers that does not sell the most cars seems to have in the market. In fact, the media have also reported that regulators have summoned a meeting with manufacturers to work in The treatment of kilometer 0 vehicles. Why has Byd opted for this? There are several reasons that explain why the Chinese company has undertaken an open race to reduce the prices of its cars. It has a large stock of unsold cars to those who need to give way after Their own promises left them obsolete Its great objective is to sell 5.5 million cars. That would force him to get into almost half a million monthly vehicles and he is not getting it at the moment It is an opportunity to clean the market and get companies in competition. Your sales muscle allows you to press more than anyone in the market and take companies to a bankruptcy of which some analysts have not notified time.

Bitcoin encryption and other cryptocurrencies will fall. And those responsible will be quantum computers

by

Experts Quantum computing They have known for several years that quantum computers will end classical cryptography. One of them, Juan José García Ripoll, a researcher at the Institute of Fundamental Physics of the Higher Council for Scientific Research (CSIC) who develops his research activity within the quantum information group and foundations of quantum theory, He warned us During the conversation we had with him in October 2019. That moment arrived in May 2024. A team of researchers from the University of Shanghai (China) led by Professor Wang Chao used a D-Wave quantum computer for I successfully violate the SPN encryption (Substitation-Permutation Network), which is a cryptographic algorithm that is used to encrypt information. This encryption is the cornerstone of, for example, the AES standard (Advanced Encryption Standard), which is used a lot. These scientists published the result of their research in An interesting article entitled “Public Cryptographic Attack Algorithm based on quantum processing with the advantage of D-Wave”. Interestingly, Professor Wang Chao and his team used two strategies to carry out their attack on cryptographic algorithms. The first one consists of broad strokes to deliver to the quantum computer the combination of an optimization problem and another search. Quantum machines are very effective when solving these challenges. And the second strategy consists in combining Schnorr’s algorithm, Babai rounding and a quantum method of optimization. In any case, the most interesting thing is that these Chinese scientists concluded that AES-256 and other military degree encryption algorithms are closer than ever to be violated. Google says that quantum machines will break the encryption of cryptocurrencies During my conversation with Juan José García Ripoll I did not let the opportunity to ask what would happen when quantum computers were able to violate the most advanced encryption technologies we currently use. “In principle, quantum computers will make the encryption algorithms that we use. For this reason there is a research area in mathematics and cryptography: cryptography resistant to quantum computers. It is a very difficult field of work. The alternative to the fact that many codes can break with quantum computers is to use quantum systems for cryptography,” Ripoll holds. An RSA integer of 2,048 bits can be factor in less than a week with a quantum computer of less than one million cubits The course of time has proved him right. And it is that several Google researchers less than a week ago They published an entry In the blog dedicated to the security of this American company in which they support a crucial premise: an integer RSA (Rivest – Shamir – Adleman) of 2,048 bits can factor in less than a week with a quantum computer of less than one million cubits. One of the most advanced quantum processors that currently exist, IBM Condor Chipagglutina 1,121 superconductor cubits, so it is evident that we still do not have quantum machines with the necessary power to violate RSA encryption. However, they could be ready before we suspect. The quantum machine described by Google researchers use noisy cubits, and IBM’s official itinerary argues that ‘Starling’, its first quantum hardware endowed with the ability to correct their own mistakes, It will arrive in 2029. Bitcoin, Ethereum, Solana and the other modern cryptocurrencies use a cryptography technique known as elliptical curve that is more robust, efficient and difficult to break than RSA, but its mathematical foundations are similar to those of the latter encryption algorithm. In fact, according to Google scientists signed by the article that I have mentioned above, if the future quantum computers will cost them less than initially breaking the RSA encryption, the cryptography of elliptical curve will also fall with relative ease. It is still not clear What capabilities will have to have quantum machines which will be able to violate this encryption technique, but According to a research group from Kent University (United Kingdom), Bitcoin can update the encryption of the entire network without “turning it off” in approximately ten months.

Apple and its apparent indifference to the AI ​​revolution reminds us of one thing: the Blackberry fall

by

Everyone is talking about artificial intelligence, and everyone is turning not to lose that train. Well, everyone doesn’t. Apple seems not to be especially interested in AI nor is it overlapping like the rest of its rivals. The question is whether that can be your definitive conviction. Wwdc sin (barely) ia. Last week the Microsoft Build and Google I/O conferences were held. In both the focus for AI was absolute. On June 9 Apple will celebrate its WWDC, and All rumors They point out that there will be hardly any news in Apple’s proposals. Instead, the company is expected to talk about the redesign of its operating systems, a project with a “Solarium” code name. Apple keeps losing trains. Apple’s apparent indifference attitude with the field of artificial intelligence is undoubtedly surprising. It is one of the most important technological companies in the world, but still does not react as one would expect from it and Keep losing trains. While the competition reacted quickly developing its own models or reaching agreements and investments with startups such as OpenAi, Apple still did not pay special attention, at least for the gallery. And what he has is disappointing. The company already dedicates thousands of millions of dollars to catch up, but when he finally presented his platform Apple Intelligence The result turned out to be disappointing. Very limited and strenuously slowly In its deployment, caution It is starting to take its toll. Not economically, but reputationally. It is not that this disappointment is pending among external analysts: it is that Even their own employees believe that Apple is behind In ia. The disaster Siri. We have seen it especially with Siri, a voice assistant who was supposed to win many integers thanks to AI but still in the development phase. The promises they made last year have not been fulfilled, and recognized analysts such as John Gruber described the conceptual videos that Apple used as “shit.” Siri’s delay, already confirmed by Appleis the definitive proof that the company is in a worrying situation in this segment. Source: Sherwood News. Remembering Blackberry. When we talk about the reputational crisis From Apple we already made an increasingly striking analogy: that of Blackberry. The company, which dominated the world of mobility with Nokia in the first decade of the 2000s, did not react to the announcement of the iPhone. He was surprisingly indifferent, and the curious thing is that the impact of the iPhone took to notice. In fact, Blackberry sales continued to grow and reached its peak in 2011. From that moment on, fallen into dive. Today the company is a shadow of what it was. Apple annual income. Has the company touched roof? Source: Backlinko. Apple is doing very well (for now). On paper things are going very well for Apple. The company has not seemed to notice the impact of the arrival of Chatgpt, and global sales continue to go up. There is signs of concern, because its star product, the iPhone, It seems to have touched roof. Now in fact the growth is much more modest (2% in 2024) and its Silent transformationalthough effective, seems to confirm that Apple is unable to innovate. Even they have made it clear that They no longer look for the next iPhone. The disruptions, it seems, are overvalued. Apple lives in the past. But as they point out In BloombergApple is living in a “legacy” world, depending on products and services that work it, but do not seem to look at the future. The agreement between Jony Ive and Sam Altman to develop an AI hardware product is another sign that may worry: the company that previously excited and which we expected a disruption was Apple. Now we see others like OpenAi or Google. An increasingly criticized tim cook. That apparent inability to react is making Tim Cook’s succession seem to press. In The Wall Street Journal summary The situation of the Apple CEO, to which the problems accumulate and that continues to focus its strategy on the inertia of the iPhone. But that inertia is not eternal: Eddy Cue, senior executive of the company, testified in the US judicial case against Apple this month and said something unique: “You may not need an iPhone within 10 years, although it sounds like madness.” An opportunity. Apple has been presuming for its commitment to privacy for years, and that was precisely the clear Apple Intelligence approach when they presented it. His promise was that of a more private AI, which we could also execute partially – without need of the cloud – and that would still be as capable as the rest. At the moment, Apple Intelligence benefits are far from competitors, but if Apple manages to catch up at the capacity of their AI and also manage to maintain their privacy promise will have something that competitors in effect do not have. Or two. But we are talking about Apple, a famous company to be late for the revolutions and then win. It should not be ruled out of course in the AI ​​segment, but there may also be new options in the field of hardware. That’s where The connected glasses They can be another accessory Very interesting For a firm that is expected to reinforce its “iPhone ecosystem” with this wearable, and the latest data They point to it.

The European space agency begins to limit when the Soviet ship will fall. Where is it a lottery

by

Like some people, there are spacecraft that say goodbye giving the note. The Kosmos 482 Soviet Missionlaunched 53 years ago with the failed objective of reaching Venus, is about to star in one of the most unpredictable atmospheric resentments of recent times. The European Space Agency is following her live. The last prediction. According to the ESA Space Waste Officethe capsule will fall to Earth tomorrow, on Saturday, May 10, 2025, at 08:16 UTC (10:12 in Spain). Although it has been reducing, the uncertainty window remains quite wide, with an error of +/- 8.61 hours. This means that the exact moment and the location can still vary (for now only latitudes above and below the 50º are discarded), but the predictions are noted as the object approaches. A capsule of the Cold War. Throwed on March 31, 1972, the Kosmos 482 ship was a twin sister of the successful Venera 8 mission, which did perch on Venus. However, a failure in the upper stage of the Molniya rocket that transported it prevented that it escaped the earth’s gravity, leaving it in an elliptical orbit with the earth all this time. What makes this event special is not only the longevity of the capsule, but the fact that it was built to survive the infernal conditions of Venus: surface temperatures of 464 ° C, pressures of 100 atmospheres and accelerations of up to 300 g. I could survive the reentry. What remains of the ship, the descent capsule of half a meter in diameter and 495 kg, was designed to support the extreme conditions of the Venusian atmosphere, so there is possibilities that it reaches intact to the surface of the earth. To survive, the impact could occur at about 240 km/h, with a kinetic energy similar to that of a 40-55 cm meteor. The big question is whether the parachute system, after 53 years and with exhausted batteries, could work. In view of telescope, the object seems to be tumbos. Prediction map on the reentry of the Soviet probe Kosmos 482. Image: that Do not panic. Taking into account that most of the planet is water, the risk of causing personal damage is “extremely remote.” And the probability of reaching a person is even lower, from 1 between 100,000 million, according to ESA. To put it in perspective, it is about 65,000 times more likely to be reached by lightning In addition, being an object that probably arrives as one piece, the risks are concentrated and therefore are lower than those created by the reentry of a rocket, which disperses multiple objects of metric size over a large area. Let’s take advantage of science. The almost spherical and smooth form of the Kosmos 482 makes it an ideal object to measure atmospheric density into very low orbits. Every time its elliptical orbit passes through perigee (the point closest to Earth), loses height due to atmospheric drag. This “accidental experiment”, which is being registered live by ESA, will provide valuable data on this type of event so far of the reentry. Perhaps a cold war ship shows us some lesson on how to reduce the problem of space garbage. Images | THAT In Xataka | There is an old Soviet probe about to fall on earth.

There is an old Soviet probe about to fall on earth. The disturbing thing is that it was designed to resist hell

by

A piece of Soviet spatial history, the Kosmos 482 probe, is about to conclude its very long 53 -year -old odyssey. And in the most disturbing way possible: falling on us. Context. Launched on March 31, 1972, this Soviet ship was destined Venus, but A failure after its launch left it stranded In the Earth’s orbit. 53 years later, its final decrease is imminent: it is expected to be re -entered into the atmosphere around May 10. The probe does not contain nuclear materials, and the risk of properties or people is low … but it is not null. And you don’t want an object of half a ton that falls from the sky to hit you. Kosmos 482. Twin sister of the successful Venera 8 mission, she was launched only four days later, but unlike the first, she failed to land in Venus. The upper Blok-Nvl stage of the Molniya rocket that transported the Kosmos 482 went out prematurely, leaving the probe trapped in a very high elliptical terrestrial orbit (initially 206 x 9,800 km high). Faithful to the secretism of the time, The Soviet Union never admitted the ruling And he simply baptized the mission with the generic designation “Kosmos 482”. After three days, several fragments that had separated from the ship rented over New Zealand, where some remains were even recovered, such as cylindrical fuel deposits. Other objects associated with the mission rented in 1981 and 1983. Designed for Venusian hell. The object that has resisted all this time is the mission descent capsule, aimed at landing in Venus. It is estimated that this sphere has an approximate diameter of one meter and a mass of about 500 kilograms. Here comes the interesting thing: this capsule was designed to survive the infernal atmosphere of Venus, a planet whose average temperature on the surface is 464 ° C. As he points out Satellite analyst Marco Langbroekit is possible that relatively whole to the reentry of the Earth’s atmosphere, although the reentry trajectory and the seniority of the capsule reduce the possibility that it is intact at the time of the impact With the parachute deployed? The imminent reentry has intensified the follow -up by satellite observers. The amateur astronomer Ralf Vandebergh has achieved telescopic images of the object in which it seems to have a parachute. “There is a compact ball, but several frames show a weak elongated structure on a particular side of the ball,” He said to Space.com. In addition, the object could be tumbos, so it is only visible at times. How to follow the reentry. Kosmos 482 Orbit the Earth every 90 minutes in a inclination of 52 degrees. This means that the reentry can occur anywhere between latitudes 52 ° North and 52 ° South. The space -track estimated reentry window and analysts such as Langbroek focuses on May 10, 2025, with an uncertainty of 2 or 3 days that will be reduced as the moment approaches. The ship will make a series of visible passes from the northern hemisphere at dawn just around the planned reentry dates. Sites like Heavens-Above already include predictions of visible passes for Kosmos 482. When the man walked on the moon. The fall of Kosmos 482 is a tangible reminder of the golden era of space exploration and the intense race towards Venus, which followed the lunar race. This 1972 relic (the last year in which man walked on the moon), will return to a radically different world, increasingly congested by thousands of active satellites and a growing amount of space garbage.

Why the fall of telecommunications was so unequal during the blackout in Spain

by

Spain plunged yesterday into a unprecedented energy blackout. A complete fall of the national electricity grid that caused problems in essential services and, above all … communications. A few hours after the Energy zero throughout All Spanish territoryoperators such as Vodafone Spain kept active 70% of their mobile network. The question is how. How the network was kept alive. Despite the national blackout, Some operators like Vodafone They made their mobile network remain active thanks to reserve generators. Although popular perception may be that the network connection is a purely wireless technology, it depends completely on telephone stations (what we commonly know as antennas), some that need electricity to function. Before scenarios such as yesterday, all protocols were activated to keep them alive despite the disconnection with the national electricity grid. This was achieved thanks to two main actors: backup batteries and structure. Diesel and batteries. Groups such as Masmobic confirm Xataka that this maintenance of the network infrastructure was achieved thanks to its reserve generators located in the stations themselves, but also to displaced electrogen groups to each area. In Spain, the Low voltage electrotechnical regulation (REBT) It demands support systems in critical infrastructure. Image | Vodafone The autonomy of these systems is limited and variable. That a station can be fed for more or less time depends on the state of the batteries, the capacity of the generators and the logistics of the fuel supply. In the best case, structures can keep the service for 24-48 hours. If we talk about reserve batteries, autonomy usually ranges between two and eight hours. This is the main reason why Some networks continued to work after the blackout and also for which others began to fail after a few hours. A progressive fall. Vodafone managed to exceed 70% activity in the network at 3:00 p.m., maintaining autonomy in its network, datacentes and systems control centers. As the hours were advancing, the figure fell. At 23: 00h, mobile traffic fell to 60% with 50% of active nodes. Reason? After more than ten hours of blackout, some of the reserve batteries began to run out. Why I had no coverage and my neighbor yes. During the blackout, access to the mobile network was (and remains) variable, and this is due to several factors. The main is the difference in backup feed systems (SAI or generators) that have mobile phone antennas. Not all base stations have the same capacity to continue working without electricity supply: some have batteries with little autonomy, other generators that require fuel (diesel or gas), and their availability and maintenance vary. In the same way, Not all operators use the same infrastructure. Each company has its own (or rented) towers and nodes, which means that two mobiles can be connected to different antennas even being in the same area. Thus, it is possible that the antenna of your operator has stopped working before, while that of your neighbor – with another operator – remains active longer. The small operators. Vodafone proved to live up to 70% of the coverage, but smaller companies, with fewer nodes to connect and lower capacity to supply energy, faced a more complex situation. The so -called virtual mobile operators (OMV) “As Digi, Finetwork, Pepephone, Lowi, etc.,” do not have their own infrastructure. Instead, they rent access to the networks of the greats (Movistar, Orange or Vodafone). The immediate translation is that its operation depends completely on the conditions of the wholesale operator in each area. If the antenna to which a user of a secondary operator connects does not have sufficient support, or if your host network prioritizes other services, the user runs out of coverage more quickly and for longer. How long would they last before chaos. Telecommunications networks can survive without electricity supply for a limited time, but are not designed to resist prolonged blackouts. In the best of the scenarios, with well -supplied structures and batteries in good condition, some stations could be kept operational between 24 and 48 hours. Beyond that threshold, everything depends on the operator’s logistics capacity to replenish fuel. In that scenario, the first to run out of coverage would be users connected to secondary nodes or small operators, while critical or priority areas (hospitals, security forces, command centers) could maintain connection for longer thanks to emergency protocols.

In times of fall in stock market, a luxury investment has become a “shelter”: bags

by

In times of financial uncertainty, generalized falls In stock markets around the world and the dollar losing credibility as a reference currency, investors seek refuge values ​​to protect their assets. The gold It used to be the safeguard In times of crisis, but a new trend has gained strength in recent years: the Investment in luxury articlesespecially exclusive bags such as Hermès Birkin. Get out of the bag to get into the bag. The attractiveness of these high -end bags signed by Hermes, Louis Vuitton Or Chanel not only resides in its exclusivity and status, but also surprise by their profitability. While actions and gold experience ups and downs, Birkin bags have demonstrated a constant revaluation of their value in the second -hand market. During periods of financial volatilityluxury bags, and in particular Hermès Birkin, has positioned itself as an asset of investment at levels of artthe high -end watches or the Classic luxury cars. According to the report of Art Market Researchin the last two decades, luxury bags have gone from being an accessory to what is now “the only category of collecting women centered.” Scarcity marketing. This investment model is sustained thanks to something as basic as the law of supply and demand. Hermès, like most luxury brands, applies a deliberate scarcity strategy with a very limited production of their pieces in which, curiously, It is the brand who chooses What products sell to your customers. The high demand for these articles causes waiting lists among their clients that can reach six years. The perception of exclusivity increases the desire for the product, which causes automatically revalue in the second -hand market when leaving the store. This is a phenomenon quite common In markets. For example, we live it after launch of the Sony PS5when these consoles arrived with counts to stores and doubled their price in the second -hand market or, at another level, with The Purosangue Ferrari. More Birkin, less gold. The Birkin de Hermès, is considered one of the best investments in the world of luxury, even surpassing traditional assets such as art or gold in terms of profitability and stability. A 2020 study Prepared by Credit Suisse and Deloitte, he revealed that the value of the Birkin increased 38% on average that year, far exceeding the performance of the S&P 500, which grew 16.3% in the same period. A study Baghunter compared the value of Hermès’ bags with respect to the S&P 500 and gold since 1995. The results showed that the financial behavior of the Birkin was much more stable and profitable than the stock market index and the value of gold, with a less volatile market and greater interannual returns. While the S&P 500 offered an average annual return of 8.65%and gold just 1.9%, the Birkin registered an average annual increase of 14.2%. A second -hand birkin: from 9,000 to $ 200,000. As with the market of the Collection luxury watchesthe high demand for certain editions of Birkin has generated spectacular revaluation. A Birkin de Hermès costs between $ 9,000 and $ 12,000, but can reach prices of up to $ 200,000 In auctions or specialized platformsdepending on its rarity, state and materials. In 2015, a pink crocodile skin birkin was sold by a record of $ 223,000, consolidating the reputation of these bags as high performance investments. The most expensive birkin ever auctioned was a Birkin 30 Himalayas with diamonds, than It reached a price of $ 450,000 in 2014. The Chinese offensive: the true value of the Birkin. In a context of commercial warfare like the current one, the boom of the Birkin as an investment has not been exempt from controversy. After the imposition of tariffs by the Trump administration, Chinese influencers networks They have started a campaign To demystify the value of these bags. During the last days, Tiktok and X They have filled with videos of these Chinese influencers directing directly to the customers of these brands by analyzing the manufacturing costs in China. The message indicates the manufacturing price of a Birkin of Hermès around $ 1,400, while luxury brands sell their bags for a price up to ten times higher than its real cost, feeding the perception that there is a speculative bubble around these luxury items.

“Someday luck will end and they will fall on someone”

by

The trend is clear. The upper stage of a Chinese rocket CZ-9 He disintegrated last night about western Mexicocausing a small stir. Nothing happened, as nothing happened a few weeks ago, when A Falcon 9 rocket burned on Polanddespite the fact that several large pieces survive the reentry and fall into populated areas. There were no regret injured when A half ton ring appeared in a town in Kenyawhen part of a Crew Dragon ship fell on a Saskatchewan farm or when the trunk of another dragon re -entered into A North Carolina Glamping. But the trend is clear. We are tempting luck. According to a Recent European Space Agency reportan average of three objects of considerable size, such as old satellites or rocket stages, re -enter the atmosphere every day. Most of these objects disintegrate during atmospheric braking; And a large number of the pieces that do not fall controlled in the Pacific. However, experts’ warning is clear: this has only begun. “We play the whole for the whole every time we have a reentry,” said astrophysic Jonathan McDowell to Space.com. “Sooner or later we will have bad luck, and someone will be injured by the fall of space garbage.” From 3 to 15 resentments per day. Only in 2024, about 1,200 “intact objects” returned to the atmosphere, without counting on the myriad of smaller fragments. Despite this constant natural cleaning of satellites and rockets, courtesy of atmospheric braking, The amount of space garbage in orbit does not stop growing. That esteem is about 45,700 objects of more than 10 centimeters orbiting our planet, a considerable increase. In addition to the frequent space releases, satellite constellations, with Starlink at the head, have completely transformed the space sector scale. “If Spacex continues with its plans to expand its constellation to 30,000 satellites, then we will see 15 daily reentrys,” McDowell explained. Starlink satellites, deployed in low orbit, have a useful life of five years. They will soon be added to the Kuiper constellation of Amazon and the Chinese commercial constellations. At the moment of truth. The vast majority of the earth’s surface is ocean or uninhabited land, so the probability that a fragment impacts a person remains very low. But incidents occur and are less and less anecdotal. In March 2024, a 10 centimeter metal fragment crossed the roof of a house in Florida, later identified as part of a battery pallet discarded from the International Space Station three years before. And what about the atmosphere? Beyond the risk of impact, another issue worries atmospheric scientists: the pollutants left each reentry. “The impact on the atmosphere is greater than ever, since more ozone destroying contaminants are ever being added,” said Eloise Marais, atmospheric chemistry of the University College in London. Most satellites are made of aluminum, which By vaporizing in the high layers of the atmosphere it produces aluminum oxide. It is known that this substance can accelerate the destruction of the ozone layer and contribute to thermal changes. Until now they were not significant amounts, but as the resentments increase, we enter unexplored terrain.

They fall in advance pieces

Tesla Cybertruck’s landing is buying all ballots to become one of the most bizarrest markets viewed so far. The electric SUV has gone through situations of all kinds, both for better and for worse. But in recent times the news about, indeed, how bad things are. The last example is a call to mass review. So massive that it forces to go through the workshop to each and every one of its specimens. The last call to review. It is believed that it only affects 1% of the vehicles but the NHTSSA (in charge of traffic safety in the United States) No choice has remained: All Tesla Cybertruck manufactured between November 13, 2023 and February 27, 2025 have to go through the workshop. The reason is as simple as some of its body steel panels can end up detaching from the vehicle. Obviously, the defect is especially dangerous if the fall is produced, which has forced to call 46,096 Tesla Cybertruck affected by this problem. A defect in glue. The problem is found in the decorative molding covered by pillar A and that extends to the rear area where the roof drop ends. The adhesive that fixes that piece may not be enough to guarantee its integrity and, therefore, the piece could fly running. Remember in The Drive that the problem has been reported by the sufficient number of people so that the company had to stop the assembly line a few days ago to apply a solution and that, obviously, its pieces are not falling along the way. “Indestructible”. When Elon Musk presented the car, he spoke of an “indestructible” body. Something more than a year later, there are only bad news around this description. To start because if a car is indestructible It’s a bad signal. Especially if you look at the tesiture of suffer an accident. Cars deform with the purpose of absorbing the energy of impact. Shock tests showed that a cybertruck that clashes against a wall absorb a very low amount of energyto the point of breaking the rear axle instead of absorbing the blow in its front area. But, in addition, we are seeing that it is not “indestructible.” At least as far as their decorative panels are concerned because it is not the first time that the Cybertruck have to be called to review because some of their panels are falling. In June 2024 there were 11,688 vehicles Those who passed in the workshop because a rear molding could be part of an incorrectly applied adhesive. Click on the image to go to the video. The eternal adhesive problem. The problem of moldings has focused the latest call calls but have not been the only ones that have starred in the Tesla car workshop. Months before, in April 2024, an accelerator problem also forced 3,878 vehicles will go through the workshop. Again, the adhesive used did not correctly fix the piece that is stepped on when the driver accelerates. That piece could detach and be located in the upper part, applying unwanted force on the pedal and, therefore, accelerating the car. It seems also that the cold is especially problematic for the moldings used in the car. As you can see In this videothere are drivers checking that when temperatures are especially low, the pieces are more likely to part. To the workshop! As we have seen, the use of adhesives has been especially problematic for the company but, of course, it has not been the only stumbling block that they have had to deal with in Tesla. In their first year in the market they called for revision up to seven times their owners. Collect in Motorpasion that in 2024 some of them were solved via Ota, such as problems with tire pressure sensors, but for others such as the fall of the Windshield molding There was no choice but to go through the workshop. The cameras and forced another update. A controversial landing. And all the above must be added that the car has not stopped adding controversies since its arrival. To start because it reached A much more expensive price of what has been expected despite having less autonomy of the fiancee. And yet First place among luxury vehicles best selling. Of course, those who wanted to test their SUBTERRENE CAPABILITIES They got the surprise that I had some problems outside the asphalt. Nor should those who decided to camp. A brake in sales? Nothing happens, it is sold The same much cheaper car removing a pair of moldings. Elon Musk’s car. The Tesla Cybertruck can boast something else: having become the vehicle that best defines the figure of Elon Musk. The car is excessive and the accumulated controversies have raised a Ultranza Defense Movement of their abilities. But it has also been the Perfect curtain to protest against the owner of Tesla and his political decisions as a member of the United States Executive. For example, projecting messages against the company and the CEO of the same.+ Photo | RANAMOTORWORKS In Xataka | Byd’s new ultra -grape load system has made millionaires to many investors: those who bet in short of Tesla
