Generate day energy and hunt asteroids at night

by

At the time they seemed the future of solar energy for their ability to follow the sun with oscillating mirrors. Today the solar concentration plants, which direct the light by heliostats towards a large central tower, They cannot compete with photovoltaic prices collapse. But when a door closes, sometimes a window opens to the universe. Short. A pilot project in the United States has begun to take advantage of these gigantic mirrors when the sun falls for the Planetary Defense. For the day, heliostats generate energy concentrating sunlight in a tower connected to steam turbines. At night, they defend the planet of potentially dangerous asteroids. The figures are devastating. The thermoelectric solar energy has lost the battle against photovoltaic by win. In 2023, the world installed the record figure of 345.5 gigawatts in solar panels, but the solar thermos I barely added 0.3 GW in total. And what is worse, since then construction is not started of no new plant. Although Spain, the world leader in concentration technology, maintains its centrals working, other projects are canceled or reconvisaged. Morocco has replaced the Termosolar part of the MEGACOMPLEJO NOOR MIDELT by photovoltaic after qualifying it as “immature and face technology”. And iconic projects, such as the gigantic Ivanpah plant in Californianow face their closure for not being able to compete with the low price of photovoltaic kilowatt. Save the planet, and incidentally investment. Given this panorama, what can be done with these huge and expensive infrastructure? John Sandusky, scientific researcher at Sandia laboratories, has been turning an idea for almost 20 years. “Heliostat fields do not have a night job. They are simply there, without using,” Explain in a statement. “We have the opportunity to give a night work at a relatively low cost to find objects close to Earth.” The proposal is not to use heliostats to take photos of the sky. Its optical quality is not enough to form crisp images such as a telescope. The genius of the proposal, embodied in a Study of the late 2024 That has already been put into practice, lies in using what these mirrors do best: concentrate light. A lot of light. How it works. The traditional method seeks in the long exposure images the steles that the asteroids leave when moving against the fund of fixed stars. Sandusky’s method is radically different and is based on frequency analysis. Instead of aiming at a fixed point, the plant’s software causes the heliostats (mirrors designed to follow the sun) oscillate, sweeping a small portion of the sky at a constant and repetitive rate. The light of the stars, swept at this constant pace, generates a signal in the tower receiver with a specific and predictable frequency. It is the “tone” base of the sky. If an asteroid crosses that field of vision, moves at a different angular velocity from that of the stars. This makes the light that reflects generates a signal with a slightly different frequency from that of the “tone” base. It is a tiny change, but measurable with current technology. And can be used to detect asteroids due to its speed relative to the stars. From theory to practice. A team has demonstrated its viability using a single heliostat, and is already working to climb the project to a large solar plant to increase sensitivity and to detect smaller and more distant objects. Even tracking satellites and other objects in the cislunar space, to sell the idea to the space force. Sandusky’s idea is a masterful example of lateral thought. Instead of building new and very expensive observatories, it reuses a multimillion -dollar infrastructure that would otherwise be inactive half of the time. A technology that fights to survive in the competitive energy market and that could find a second life, a second job.

Awakening in the middle of the night is common

by

It can be something occasional or something recurring, but it is something that happens to almost everyone (especially as our age progresses), waking up in the middle of the night. Sometimes it occurs for no apparent reason, although this “apparent reason” can be a night visit to the bathroom. Waking up in the middle of the night can be usual, but why does it happen? The question is important although it also hides another that many people will have done. It is the one, regardless of the annoyance, it is this loss of sleepworthy sleep. Sleep interruptions can cause insomnia problems, but can also respond to other stimuli of different kinds. In a recent interview in The avant -gardeSleep Psychologist Roser Gort pointed out some of the factors that can contribute to these inconvenience. First of all, GORT indicated that sleep interruptions are usually completed a pair of sleep cycles, an important factor since these cycles are linked both with the depth of our dream and with the very function of this. During each sleep cycle our brain passes through four phases: a REM phase (rapid eye movements); and three phases NO-REM, each deeper than the previous one. The REM phase is the phase in which dreams occur and in which it is easier to interrupt the dream. During a typical night we cross several cycles but the relative duration of each phase in them changes, as well as the very duration of the cycle: the first cycles will see longer deep phases, while in the final cycles the REM phase will gain prominence. If we generally wake up a couple of cycles, it is logical that we always wake up at the same time. But let’s go back to the key matter: what are the factors that make us woke up easily. Stress is one of them. According to Gort indicatesthe cortisol (the colloquially called “stress hormone”) tends to accumulate in our body from a certain time of the morning (between two and four) when our stress levels are high. The early appearance of This hormone It can facilitate we woke up at such hours in the morning. “Stress can also harm the quality of your dream,” they explain from Sleep Foundation. “Sleep and stress are probably affected by each other, with poor dream impacting your ability to manage stress and stress by impacting your ability to sleep well.” From the Foundation they also point out how The hormones They can also play an important role in these contexts. Hormones play a key role in the functioning of circadian rhythms, the “internal clock” that indicates when to sleep and when to remain awake. Hormonal changes, Add the FoundationThey can take you to wake up in the middle of the night. This also implies that events that influence our endocrine system, such as pregnancy, can affect our sleep and vigil cycles. One of the factors that can affect the continuity of our dream is age. As we become older, our body requires less sleep. This not only affects the total of hours that we sleep at night, it can also increase the probability that we wake up in the middle of the night without apparent reason. Some sleep problemssuch as insomnia or sleep apnea can also be behind our problems to keep us asleep. Finally, there are external factors that can also influence our ability to sleep “from the pull”. Factors such as our daily habits or medications that we can be consuming can also make our dream more fragile. Recovering the dream Waking up in the middle of the night can be a problem for those who have difficulty falling asleep. Awakening in the middle of the night can mean to lose a valuable sleep time, so some experts have been interested in this find ways to reconcile sleep quickly and effectively. Often We can wake up With the prevailing need to urinate. The problem is that this visit to the bathroom can contribute to reveal us making us more difficult than we reconcile the dream. According to Gort explainedit is not so much our bladder that awakens us on such occasions but that when we wake up we realize that we have to release its content. If we want to avoid this we can reduce our fluid intake in the hours before we go to bed. Avoiding this night walk can help us, but experts suggest A series of tricks To help us recover sleep. The first: not to look at the clock to check the time it is, since this probably generates anxiety and makes our dream difficult. There are almost as many ways of sleeping as people. Our dream depends on many factors, such as biological, work or social.

In India there are cities that have 40ºC on the street at 10 in the morning. So they have started living at night

by

Spain is currently the best example of A problem much deeper that arrives with infernal heat in much of the planet: How to fight the fire with the working day (and life in general). Five workers died during the first heat wave, and that is why it is prioritized Adapt the day (or suspend it) when those hours arrive in which Sol does not let us move forward. And, meanwhile, in India it is 10 in the morning and they already have 40 degrees. How the hell do they do? Heat as law. He counted The New York Times In a report how fire is fought in the city More suffocating. In Sri ganganagara semi -desert region of the Indian State of Rajastáneveryday life has adapted to temperatures that, in the middle of June, reach 49 ° C. There, where dawn already begins at 30 ° C and by 10 in the morning the thermometer exceeds 40 ° C, heat is not a seasonal phenomenon: it is a structural condition that conditions work, health, rest and human relationships. The population, mostly agricultural and without access to comforts such as air conditioning, has developed A daily choreography that folds to the abrasing rhythms of the weather and the sun. Follow the sun. The key? The working days begin Before dawn: peasants and workers take advantage of the few fresh hours to work in the fields and constructions, before taking refuge where they can when the sun is It returns unbearable. The houses are emptied at noon, the markets close, and the few active services, such as street food carts, work under temperatures that melt the asphalt. The scene is repeated every summer with an increasing intensity, aggravated by a rising humidity that multiplies physical suffering. Sunset in Sri Ganganagar The thermal abyss. We go from Sri ganganagar to another “extreme” region. They explained In Bloomberg that in the western city From Ahmedabadwhere the thermometers They usually exceed The 45 ° C at the beginning of May, the fight against heat has also ceased to be a seasonal issue to become a structural need. In this environment, exposure to the sun is no longer just a job risk: it is a threat direct to healthfood security and economic stability of millions of people. For women Like Kunwar Ben Chauhanthat sells meat in the street and has suffered fainting, dehydration and economic losses due to the deterioration of its products, the extreme heat imposes impossible dilemmas: going to work and risk life, or stay at home and lose daily sustenance. Faced with this reality, groups such as Self-Employed Women’s Association (SEWA) Pioneer solutions like The parametric insurancewhich grants automatic economic compensation when the temperature exceeds certain critical thresholds. The measure, although modest, represents a vital lifeguard in an informal economy where many workers earn just three dollars daily. Ahmedabad Adaptation from below. In Ahmedabad, a more metropolis of 8.5 million Of inhabitants, resilience is built from the community fabric. In addition to climate insurance, initiatives such as ceilings coating With reflective paint and the installation of early alert systems are transforming the way heat is perceived and managed. The city, a pioneer in Asia del Sur, launched in 2013 Your own plan of action against heat after the devastating wave of 2010, in which they died More than 1,300 people and even 400 bats They fell dead by the burning air. Since then, the actions They have multiplied: Hospitals now have special rooms to treat heat stroke, dehydration and burns, community centers, temples and shopping centers become climatic shelters during the most extreme days, and awareness campaigns have been implemented through radio, neighborhood leaders and educators. The plan includes a alert system colored by colors that informs the population, and whose effectiveness has contributed to reduce mortality. Heat and health. Back to Ganganagar, He underlined the Times Other strategies. In the Chak Maharaj Ka clinic, patient flow increases as heat becomes unbearable. Those who suffer from previous diseases such as asthma or gastrointestinal conditions see how their ailments intensify, forcing medical staff to resort to rapid and palliative treatments. Most of the inhabitants have internalized basic strategies Survival: avoid going out in critical hours, hydrating with homemade solutions, or resting under trees when there is no other option. It happens that these methods only partially relieve a problem that threatens every aspect of life. In the epicenter of heat, in the city itself, the activity never stops at all. As In Ahmedabadworkers cannot afford to rest: if they don’t work, they don’t eat. Solidarity under the sun. Despite the relentless environment, gestures of daily humanity arise that become pillars of a shared ethic. At 3 in the afternoon, when the temperature reaches its maximum point in ganganagar, whole families go to the road with water cubes to offer relief to motorcyclists, truckers and travelers stunned by heat. The act, although simple, embodies a deep sense of charity in a society where doing good is seen as the way to Spiritual salvation. For many, giving water to a stranger is the only lasting legacy that can be offered in a world where everything else is Evapora Under the sun. Climate Innovation Laboratory. Behind the plan of action pioneer of the city of Ahmedabad there is a growing understanding that heat is not an anecdotal phenomenon, but a dangerous multiplier of vulnerabilities in a country where cities They grow disorderlycement replaces vegetation and global emissions have raised the average temperature of the planet in 1.2 ° C. From the pre -industrial era. Recent studies They warn that if global warming exceeds 2 ° C (one possibility every time closer) India will experience an increase Six older in the frequency of heat waves. Already today, More than 600 million Indians live under an unprecedented thermal threat. In that scenario, the city has become a Adaptation Laboratory urban, whose innovations (such as Insurance algorithm which contemplates variables such as night temperature, cloudiness and pollution) are being … Read more

A strange night a whistle has been listening for weeks in Vigo. They just found the culprit

by

There are phenomena whose sounds They challenge not only reason, but even the very perception of reality. One of them is remembered in Scotland Since the late 90s, a low frequency buzz that is heard in different enclaves and that in recent times he has returned strongly. In Spain something similar to this part happened in an area of ​​Vigo. Weeks with acute noise when the night that had altered the dream of the neighbors. The problem is that they have just detected the “guilty”, and has a difficult solution. The mystery had wings. It The Faro de Vigo had. For weeks, the neighborhood of Vigo’s journey and Aragón Street has lived in confusion and irritation because of an acute, intermittent and persistent beep that began at nightfall and repeated every two or three seconds until dawn. The initial suspicion fell to multipable guilty: a spoiled alarm after the blackout of April 29, a port of the port amplified by the wind, or even some damaged traffic light out of decibels. The neighbors, unveiled and perplexed, mobilized to find the origin of the annoying sound, called 010, patrolled the streets in search of sound tracks and requested the intervention of the local police. In the end, neither industrial alarms nor port machinery: the author of the beep has turned out to be An unexpected creature and surprising, whose presence had gone unnoticed until then because of its historical silence and its expertise for camouflage. Small and nocturnal. Yes, apparently, the Local Police, after inspecting the area and confirming that it was not any mechanical source, identified the person in charge: a European autillo (Otus Scops), one of the smallest raptors in Europe (does not exceed 20 cm in length or 100 grams of weight) whose song remembers a high frequency electronic whistle. In fact and how I told the middle The biologist of SEO BirdLifeGustavo Ferreiro, the repetitive beep is part of the AVE mating ritual, which is in this time in an incubation phase. In other words: the autillo does not sing to bother, but to communicate its presence, claim territory and maintain the link with your partner during the breeding. Invisibility. Although common in southern Pontevedra, his nightlife and his perfect camouflage among the trees make him an almost inhabitant invisible which can only be detected by your voice. In this caseHabitat’s choice was an urban environment with dense vegetation and old trees, which surround the Matías Park and a nearby abandoned house. European Autillo Survival paradoxes. The case also offers other readings. The paradoxical is that The European Autilloonce a rural bird, it is today forced to take refuge in urban environments due to the loss of biodiversity In the field. Agricultural intensification has eliminated large trees, essential for nesting, and the massive use of pesticides has decimated insect populations that are fed. Thus, the natural habitat has degraded to such an extent that birds seek shelter in urban parks, where they can still find cavities and some food. This forced migration to the city is a reflection of the ecological decline in which the species is found, already included in The “vulnerable” category In the Red Book of the Birds of Spain 2021. Thus, the presence of the Autillo in Vigo is not an isolated anomaly, but rather a symptom of a deep change in the distribution and behavior of many species affected by human pressure on ecosystems. Endangered species. The case of the beep in Vigo demonstrates how a daily discomfort can actually be the life sign of an endangered species. What began as a sleep disturbance became an opportunity to reflect on coexistence between the city and nature. The case reminds others where the presence of cities ends up modifying the life of species. In fact, in Valencia something similar has happened With another copy. EITHER In Icelandwhen the frailecillos season begins and humans hunt them and throw them through the cliffs (by A good reason). In this case, climate change and cities lights threaten the survival of birds. With the autillo, the loss of biodiversity is what is throwing them into such Obern Like cities. That said, and if everything follows its course, the song will send for the neighbors in August, when the chicks and the priorities of the bird change from the courtship to the care.

Seville wanted more security in its streets at night. So he has recovered an old figure: the serene

by

In many towns and cities of Spain, serene are a I remember distanta another time figure that he was in charge of around night through the streets while the rest of the neighbors rested in their beds. In Seville no. There the City Council decided to recover them to late 2023 And the experience has been good enough so that now, once that test is over, he has decided to return big, with more personal, more hours and covering more neighborhoods. Its mission will not consist of replacing the police, but in something much more interesting: demonstrating that serene can fit in the 21st century. What happened? That Seville wants that at night its streets are monitored by a figure that has disappeared in most towns and cities of the country: the serene. And he wants to do it big, in addition, dedicating considerable investment to the program (around 2.6 million euros) so that the guards can cover a large part of the Hispanic capital during every night of the year. Why do you do it? It may be shocking at a time when cities are already controlled by municipal agents and other agencies responsible for ensuring the safety of neighbors and businesses, such as the National Police, the Civil Guard or 112; But Seville acts with knowledge of cause. The Consistory already launched a program with “civic agents” to late 2023a service that worked for months and gave such good results that He wants to consolidate it. What do they do? The Hispanic City Council It makes it clear: The serene figure is not intended to replace the Polysa. On the contrary. His mission is to complement the work of the agents, inform neighbors and tourists, mediate in conflicts, accompany people who may need it, such as the elderly, dependent people or lost visitors, notify problems in urban furniture and alert the Cecop (Operational Coordination Center) Before emergencies. They are a “first proximity front”, In words of the Consistory. Their first year of operation gives a clear clue what the serene can contribute. In just one year they gave almost 500 notices To the CECOP room to inform open shops, problems with lighting, robberies, fires or medical emergencies. In Seville they have accompanied people at night, advising, mediating in the attention to homeless people and even provided “Preventive Protection” to a clerk before a case of harassment. And what does the City Council think? Its mayor, José Luis Sanz Ruiz, I made it clear This week when announcing the commitment redoubled by the serene: “we launched a pilot project in 12 neighborhoods of the historic center and the balance was quite positive. It has achieved a better coexistence, more security for neighbors and better job opportunities for hired people.” That first test was in fact launched as part of a public employment plan that ended Last December Without option In extension. Hence, now the Consistory has tendered a contract for the service to assume a company As of Octoberbetween the 1st of that month and on September 30 of the next year, although the sheet contemplates that the contract can be extended. What will the service be like now? Much more ambitious. If the pilot project had 18 “civic agents” and two coordinators, the new service will expand its seedling until adding 36 agents and two coordinators. This increase will also allow them to expand the Seville area that supervise: of the 12 neighborhoods planned in the 2023 plan, it will be passed to 26 zones. As for the schedule, the serene will be in charge of making rounds from 23.00 to 7.00 h 365 days a year, an hour more than before. That increase is possible thanks to a greater economic effort of the institution. The pilot program was financed by 725,800 euros. Now the investment is triggered to rise to 2.6 million euros. In that amount, They clarify at the City Councilthe salaries of the agents and the material they use, from geolocation devices to the clothes that identify them as serene are included. Are they exclusive to Seville? No. Although Seville has stood out for his commitment to the “civic agents” is not the only town in Spain that keeps serene. His figure has also recovered in Several municipalities Catalans Another example is Gijónwhat are you doing More than 25 years He decided to recover them to make rounds through the streets of the city from entrance at night and to the early morning. His work is very similar to that of his colleagues Sevillians: they help neighbors, merchants and tourists, prove that urban and lighting furniture is in good condition, they inform and warn the police in cases of robberies.

Do not get night on solar panels

by

Suppose you acquire the power to cancel the night in a certain place in the world; of reflecting sunlight from space to illuminate something concrete, so that it is made from day in a given area. What would you use it? Orbital reflect. A Californian startup wants to obtain this power to illuminate the photovoltaic panels in the hours close to dawn and sunset, when I miss its renewable energy, and when the energy companies could sell more. Orbital reflect has just received 20 million dollars in financing, which will use to deploy a constellation of satellites equipped with gigantic mirrors. Its objective is to reflect sunlight towards Earth on demand. The sun to the letter. The concept is simple: to increase the production of solar energy on the earth directing sunlight to the large photovoltaic plants of the soil before dawn and after sunset. Like the space solar stations, but without the complications of concentrating the energy in a laser or microwave beam, placing large mirrors in orbit would significantly expand the light time that a solar farm receives to generate electricity, solving one of the great Peros of solar energy: its intermittency. The company has already performed tests with a mirror in a hot air balloon at almost 3 km on a solar farm, generating 500 watts of energy per square meter of photovoltaic panel with approximately half of the brightness of the sun. A first demonstration. The first orbital reflect mission is scheduled for the spring of 2026. A demonstration satellite will test a 18 x 18 meter mirror made with mylar plastic tensioning to form a solid reflective surface. It is expected to reach a brightness of 0.1 lux, comparable to a full moon on a clear night. The mission aims to illuminate 10 iconic locations during the night to generate dissemination and public interest. An ambitious goal. The initial idea contemplates a constellation of 57 small satellites in a synchronous polar orbit with the sun, about 600 kilometers of altitude. They would provide about 30 additional minutes of sunlight to photovoltaic plants. In the long term, orbital reflects plans to launch a constellation of thousands of satellites with much larger reflectors, up to 55 x 55 meters. On this scale, the total luminosity of the constellation would be comparable to that of the sun at noon. Other applications. Although the impulse to solar energy is the final objective, the company has plans to generate short and medium term income with other applications. Since its foundation in 2021, the company has received more than 260,000 applications from 157 countries for its sunlight delivery service. Among future services, they offer the lighting of night construction projects, public events, disaster help efforts, and defense operations. “We want it to be as easy as possible: you enter a website, you tell us your GPS coordinates and we send you some sunlight after dusk,” explains the CEO of orbital reflect, Ben Nowack. Science fiction made reality. Image | Orbital reflect In Xataka | Space energy never worked. A military escalation in orbit is making it come true

diurnal solar surpluses, night spikes … and increasingly cheaper batteries

by

For years, conversation about the future of Spanish electricity has been reduced to fear of two words: “China photovoltaic”. Panels cheap and reasonably efficient. But the final weapon is not arriving in containers from Shanghai, but increasingly frequently in the van of a neighborhood installer: lithium batteries packs that allow reducing the dependence of the conventional electricity grid. Cut the cable. Or, at least, loosen it. The cheaper that changes the rules Past, present and future of the storage price: 2015: Storing a kilowatt-Hora cost more than 1,100 dollars/kWh. 2024: according to Bloombergnefthe average price of the pack was at 115 dollars/kWh (about 105 euros/kWh), after a 20% drop in the last year. 2026-2027: By then, the same consultant estimates that the psychological bar of the 100 dollars/kWh will be broken. With these prices, Storing domestic energy costs less than the term valley of the PVPC ratewhich now ranges between 0.11 and approximately 0.13 euros/kWh. That makes the battery the natural complement of any roof with panels and a direct enemy of the demand managed by the distributors. To understand the impact of this cheaper on the accounts of the companies in the sector, you have to understand how they earn money. Iberdrola. Its 2024 ebitda, According to its annual resultsit was almost 17,000 million euros, broken down like this: Networks: 6,423 million euros. 38% of the total. Generation and customers: 10,425 million euros. 62%. 52% of Iberdrola’s investment goes to networks, its most stable and regulated segment. Endesa. Its 2024 Ebitda reached 5,300 million euros, with a similar distribution: Electric distribution: 1,750 million (approximately 33%). The rest comes mainly from generation and marketing. Naturgy. With an Ebitda of 5,400 million in 2024: ELECTRIC NETWORKS AND GAS: They represent approximately 45% of the business. The company has increased its investment in this segment by 15% compared to the previous year. For all these companies, Each kilowatt-hora that does not circulate through its networks directly impacts its profitability. Today, the threat is hypothetical, but tomorrow it will be arithmetic. Battery and panel: the combo that takes off According to data from Auto: In 2021, only 2% of residential facilities included battery. In 2024 that figure reached 71%. And they are not just coastal chalets, hybrid kits reach peripheral single -family and even communities of pioneering neighbors. With subsidies and 2.0TD rateamortization drops between 6 and 8 years, and energy self -sufficiency touches 80% in optimal conditions. Electric grid as electron pipe begins to stagger. And not only because of the fall in the demand managed, but because the flow is reversed. In the moments of sun and low demand, thousands of homes are beginning to return energy to the network or simply not need it. For a company that invests billions in transport and distribution infrastructures, that is a problem. But the regulatory framework is starting to move. And your address is not clear. The CNMC has on the table The new toll methodology for the period 2026–2031. Among the Options in consultation: Move part of the fixed costs of the network at the end of power, and begin to remunerate flexibility services, such as storage or coordinated discharge of domestic batteries. They are two changes with opposite consequences: The first penalizes the self -consumer with drums, although he barely consumes. The second rewards it, if your battery helps to balance the network at critical moments. Everything will depend on how normative design is related. And who is heard more. But for now, the government Last the arrival of aid for energy storage through 700 million Feder funds. This transformation is not an isolated case. Several European and American electricity have understood the message before the Spanish. And they have begun to move. Nextera has already hired 81 GW from Solar With storage for 2027, with a good part behind the accountant. That is, in homes. Enel x He has launched virtual power plants pilots (VPPS) In Italy and agreements to display regulated batteries. EDF He is exploring flexibility markets in the United Kingdom and France. In Spain, Endesa has timidly begun to explore this land with its project FlexiCy In Malaga. The background logic is clear: The network will remain necessary, but less as a unidirectional route and more as a smart platform for exchange and balance. And the interesting thing It is not so much the exact point in which we are, but the slope of the curve. According to The International Energy Agencyto meet the objectives set in COP28, world storage capacity It must be multiplied by six before 2030. Of which 1,200 GW must come from batteries. Spain, with its diurnal solar surpluses and nocturnal peaks of consumption, is one of the most fertile land in Europe for that transition. Despite the fear of these years to the threat that came by boat – Chinese plates – the real threat is the one that arrives in a van. In lithium, phosphate and iron packages that allow each home to keep their own energy. In that context, The network business is focused on a transformation: to bill kilowatts to offer guarantees of energy continuity. And there is the key: whoever adapts to the new model will not only resist better. You can also lead it. In Xataka | We have second to second the data on the great blackout in Spain.

A huge blue spiral appeared in the sky of Europe at 9 at night. It was the wake of a spacex rocket

by

It is hard to believe, but the last night were not aliens either. If you were looking at the sky at 20:55, European central time, you could see a bright blue spiral illuminating the night. It was a Spacex rocket. A strange show. In United Kingdom, Belgium, Poland either Ukraine. From The clean skies of Sierra Nevadain Granada. Virtually all of Europe has managed to capture the spiral light that crossed the sky last night. They soon appeared photos on social networks. People asked what that strange phenomenon was. It is not a usual show, although it has already been seen in Hawaii, Alaska either Iceland. A Falcon 9 of Spacex. Neither a missile, nor a satellite, nor a galaxy about to swallow us. Nor a UFO. The object had a name and surname because it was a Falcon 9 rocket of Spacex by recentrating in the earth’s atmosphere. He had taken off from Cabo Cañaveral, east of the United States, two hours before. The Spy Nrol-69 satellite of the American National Recognition Office (NRO) had put in orbit. And he was returning to the earth to disintegrate in the atmosphere in a controlled way. What caused the spiral. Before a controlled reentry, the 13.8 -meter length rocket rotates to get rid of the fuel that is still in its deposits; A process called passivity. The low temperatures instantly froze the propellants released by the rocket, which added to the turn movement and the position of the sun caused the light show over Europe. The turn is what made it look like a spiral, and the sunlight was what illuminated the frozen wake. Nothing to do with the incident of Poland. In February, the second stage of a Falcon 9 rented without control over Europe. Several pieces of the rocket fell into populated areas of Poland, without causing damage (except the dismissal of the president of the Polish Space Agencyfor its management of the incident). In this case, and as is usually the case, the second stage of Falcon 9 successfully turned on its engine to fall controlled in the atmosphere, far from populated areas. They were the light conditions and the flight profile that made its wake visible in the European night sky, without further consequences than the scare of some European spectators.

More than a decade ago, Seville created a system to defend against Guadalquivir waiting for not having to use it. Last night he had to activate it

by

Anyone who was yesterday at the entrance to the Pava Charco, could see how the city’s firefighters They moved the huge gates of defense that shield the city of Seville of the floods of the Guadalquivir River. And it is likely not to know, but I was attending a historical moment: it is the first time since it was built that these steel plates (more than four of meters high and five tons of weight) have to close. Phase 1. Yesterday afternoon, the Hispanic City Council activated the emergency plan in phase 1 and brought together all emergency services (including Local Police, Civil Protection, National Police and 112) to coordinate the necessary measures. 30 people were evicted from a “chabolist settlement” that was in flood zone, control points were installed and It was decided to close The connection that connects La Vega de Triana with the city. That’s where the doors that have just closed are. He has also put the neighbors of Tablada, Valdezorras and El Gordillo on alert. But hadn’t it stopped raining? Yes, weather forecasts They do not show abundant rains In the area and in fact (although the red alert is maintained) the river flow has already begun to decrease in Córdoba. However, when we talk about Seville, the river is just one of the things to take into account. The tide. Although it is often difficult to imagine, the truth is that when the Guadalquivir arrives in Alcalá del Río (that is, 15 kilometers before reaching the municipality of the city of Seville) It is already at sea level. That makes that point more or less, the entire riverbed is subjected to the influence of the tides. And that is what worries the authorities: if the river flood coincides with the pleamar, the chances that the Guadalquivir will overflow begin to be huge. How historical is this really? Indeed, to say that the doors have closed for the first time is not saying too much: they settled in 2012 and the last time the city was on the edge of the debacle It was in 1996. However, the challenge is more than considerable. Because, like Díaz del Olmo explained years agoProfessor of Geography of the University of Seville, the reduction of the alluvial plain of the Guadalquivir (which has gone from 4 kilometers to 500 meters) adds risks to the situation. “It is worth that with the swamps that retain the water, so much alluvial plain is needed, but the current one is not much less sufficient,” he said. And not only for the plain itself, but because “If the river is wide and with meanders, the energy that the water carries is blurred; but if it is narrow and straight, the water acquires a great speed … like the flow of the river rises of the 4,000 cubic meters per second … we have a problem for which they do not serve neither the storm tanks or anything.” A monster called Guadalquivir. Luckily, we are not yet in that situation. However, this is a warning for navigators: taught by tons of concrete, rivers are sleeping monsters, but monsters after all. Just yesterday we talked about The great paradox of our time: Have to prepare for long periods of drought while we have to have infrastructure to contain torrential rains. Today we see that it is not something punctual, it is the true “new normality.” Image | Toni Pomar | ECMWF In Xataka | With the reservoirs to be overflowed with the rains of March, there is a reason for hope on the horizon: the light of the light

The iPhone is seen in its greatest filtration to date. It is a crazy night between iPhone 14 and iPhone 8

by

The fourth generation of iPhone se It will launch this week, According to the most recent leaks. It is not unreasonable to think that it will be, since the design of this phone has just been known practically. The filtration shows that, supposedly, will be the iPhone stops this 2025, a phone that would inherit components of the iPhone 14betting on his classic strategy of just one camera. Hi, iPhone 14 … or iPhone 12. Notch, you again here. It seemed to have disappeared with the arrival of the iPhone 15 Basethat hugged the Dynamic island of the iPhone 14 Probut I was just Parranda. According to the leaks, the iPhone will be inherited a frontal front of previous models, with notch but a good screen use. This would be 6.1 inches, OLED and with Full HD+resolution, the same one we have seen on the iPhone of previous years and with less than the 2,000 nits implemented from the iphone 15L. What does not appear anywhere is the action button, Apple’s last idea for its generation iPhone 16. The rear … to the iPhone style. How strange it is seen a mobile phone with a single camera. This iPhone would arrive with a single sensor, predictably 48 megapixels, which would allow it to make “optical” (sensor cut) of up to two increases without loss of quality. The resignation of the ultra wide angle may seem more serious than it really is. This is the camera less uses (and of lower quality) in general terms, so sacrificing it to adjust the price of the phone to the maximum it is not a bad idea. The rest of the hardware. Apple would not want to give up Apple Intelligence with its se, which would force the company to implement the Apple A18 Bionic and a minimum of 8 GB of RAM. As a curious fact, it is rumored that this phone would arrive with its own modem for 5G, to save costs compared to Qualcomm. In short, a 2025 hardware device and airs a few years ago, at a price that is expected below 600 euros. An access alternative for those who want a new iPhone without spending too much.
