Wanting to avoid fires in Oviedo, the cleaners have encountered another problem: the Civil War

If we believed that Spain had already cataloged every last vestige of the Civil War, bad news. Artillery corners still pop up like mushrooms in autumn. Scars of a territory that reminds us of a broken country. Imagine the look on the faces of the city hall’s cleaning professionals when they put the brushcutter where it didn’t belong. Imagine the face of the municipal crew of Oviedo: cleaning any path in the municipality of El Campón in the middle of July, the machine trips over reinforced concrete and an embrasure from 1937, hidden under the ferns for 89 years. Anyone who knows Mount Naranco is not surprised. Those who only follow guided routes, tourist plates and school manuals, will be amazed. A front under the bushes. The archives say that Oviedo endured a republican siege in 1936 which ended up breaking towards October. So, Naranco was filled with trenches to watch the steps towards Grado. In El Rebollal they counted thirteen positions: two for machine gun, eleven for rifle. Campo Cimero has thirty-one, distributed in four arches towards the northwest, the largest defensive complex in Asturias. To cite an example, in Ayones the nest preserves its original geometry: seven sides on the outside, cylinder on the inside, built in 1937 by the Republicans. And of course, the undergrowth does not erase these structures, rather it preserves and contours them. And except for the nationalist constructions of Pando, almost everything preserved in this area—Rebollal, Campo Cimero, Fitoria, Ayones—is republican. Spain’s wounds. Although no one has the exact figure, the BunkerAtlas portal has registered and geolocated 192 positions. It is more of a sample than an official census, of course. Madrid concentrates almost 19% of what is catalogued; Catalonia is around 16%; Navarra 12%; Aragon 11%. And almost six out of every ten registered structures were built during the Civil War, by both sides. Only in Madrid have they documented more than 2,000 fortifications in a hundred municipalities, about 500 concrete; The capital already has 531 inventory tokens between Casa de Campo, El Pardo and Ciudad Universitaria. In the Pyrenees, the Franco regime designed Line P: ten thousand bunkers planned along 500 kilometers of border. Luckily the work stopped with less than half built, about 4,000, and became obsolete around 1980. Multiply that by each front—Ebro, Jarama, the Oviedo fence itself—and the real figure is surely around tens of thousands. Most remain under brambles, awaiting clearing. Who decides what is saved. Spain catalogs this heritage since the Historical Memory Law of 2007, expanded by the Democratic Memory Law 2022—revised March 2026—. Both require identifying and protecting these remains, and in some cases opening them to the public. The problem, as always, is one of resources: inventorying thousands of kilometers of trench costs money that does not always arrive, and each recovered nest depends on a city council, a memory association or a forestry crew that stumbles upon it. Present over past, as always. Let’s think about The Carmen of the Martyrsthe most beautiful garden around the Alhambra, which stands above the old Corral de los Cautivos, where Christian prisoners spent the night in Arab dungeons. After the Civil War it served as a residence for young people. In 1970, a hotel project razed a good part of the historic forest, until neighborhood protests stopped the work. Or the Turó de la Rovira. Everyone knows it as the Carmel Bunkers, although the name is a historical error: there was never a bunker or underground shelter there. What the Republic installed in 1938 was an open-air anti-aircraft battery, four 105 mm Vickers cannons, to stop the bombing by Italian aviation over Barcelona. When the war ended, the Republican army disabled the pieces and withdrew, leaving the concrete empty. Today is the most photographed sunset in Barcelona, ​​a nest of tiktokers. The other urgency: summer rules. The reality is that the vestige found in El Campón responds to a key action and none of this should stop the clearing. On the contrary. The summer of 2026 is already the worst start in the historical series: June closed with 90% more burned area than the average of the last twenty years, and quadrupled the data for the same month in 2025. The Almería fire devastated nearly 6,600 hectares, with projections that are close to 7,000. The European Union launched its largest historical firefighting deployment and it is not easy to suspect that it is still insufficient. Perimeter clearing responds to the law. Although the hoax that environmental regulations prohibit cleaning the mountain circulates every July; Neither the 2030 Agenda, nor the European Green Deal, nor the Forestry Law prohibit clearing. They demand it, with an annual plan. Memory and prevention do not compete. All you have to do is notify Heritage, let the nest breathe for a while in the sun and then decide what to do with it. The Civil War remains buried in half of Spain; chainsaw is just what is needed to clear brush and clean up against the spread of fires.

China is successfully replacing a 19th century industry with drones: skyscraper window cleaners

When we think of skyscrapers, the Western culture in which we have grown up makes us inevitably associate them with the United States and iconic skylines in cinema such as New York or Chicago, but the current reality is very different: China is the country that breaks the cord, according to the Council on Tall Buildings and Urban Habitatthe world’s leading authority on the classification of tall buildings: it is home to more than half of the world’s tallest skyscrapers. This architectural explosion has created an unprecedented maintenance challenge: having to clean millions of square meters of glass and metal facades. What started as a need for manpower has become a testing ground for advanced robotics and unmanned aviation thanks to a state plan called “Robot+” that automates tasks to compensate labor shortage. One of the most striking recent examples: automated cleaning from Nanchang Railway Station. Goodbye to human window cleaners. The traditional Spider-Man of buildings is disappearing and it makes perfect sense: the risk of accidents and the climatic conditions of cities like Shanghai or Guangzhou have made this profession increasingly less attractive for new generations, so cleaning companies it is difficult for them to find relief: the perfect scenario for automation. Furthermore, the data from cleaning drones is compelling: going from being able to clean 200 square meters a day to 10,000 with a cost between 10 and 20% less, according to the Wuhan startup Aero Technology collected by China Daily. Drones are best suited to difficult outdoors such as corners and nooks and work even on rainy or windy days without risk. And when finished, the drone uses its camera to capture images of the clean surface, which it transmits to ground personnel for review. If it doesn’t comply, give it a review. Why is it important. We have already glimpsed some of the advantages of automating cleaning at height, but one is truly essential: safety. According to the WHOfalls are the second global cause of death due to unintentional injuries, only behind traffic accidents, with about 684,000 deaths annually. In the specific workplace, they constitute one of the main risks in sectors such as construction or industry. especially dangerous are the falls in height. In the United States, OSHA data They return that falls represent between 35 and 39% of construction-related deaths. In Spain, falls from height represented in 2024 12.2% of all work-related deaths during work hours in all sectors and this year alone they cost the lives of 79 people in the Spanish state alone. The other big advantage is price: less labor, less operating time because they clean faster, lower equipment costs, and lower insurance premiums. Aero Technology quantifies savings between 10 and 20% compared to traditional methods, although the drone company Apex is more optimistic for your business, raising the range of savings up to 30 or 50% (although the reason is probably that you consider assemblies like scaffolding). Regarding water consumption, a study by Shanghai University of Engineering has shown which spends 21.8% less. Context. China faces the worst possible scenario in this framework: it is the country with the most skyscrapers in the world, it has a lot of air pollution that quickly dirtys its facades and it also suffers labor shortage for manual jobs. Although if we are looking for pioneers in the drone cleaning segment we have to go to the North American one. Surname born 2014, the Elevation from the Swiss Aerotain AG back in 2015 or the Norwegian KTV Working Dronethe owner and mistress of drone window cleaning is China. China had been preparing the ground for years, as demonstrated by different academic research papers on glass and facade cleaning robotsas this of cable-driven parallel robots from Tsinghua University or this other of fan-powered cleaning robots from the Harbin Institute of Technology. The Asian giant has the academic ecosystem, state financial support and an obvious need. Said and done: China was the one who democratized technology, moving from prototypes and more or less “artisanal” devices to large-scale production with scalable industrial systems and companies like DJI, UAEAV and Foxtech. Today they already produce between 80-90% of the world’s commercial drones and lead an industry that in 2024 was valued at 248 million dollars and has a projection of 1,257 million by 2033. according to Growth Market Reports. The substitutes. China has developed a complete industrial ecosystem that is essentially divided into two major technological aspects. On the one hand, high-pressure cleaning drones that are connected to water pumps that are on the ground, such as the DJI M400 or the solutions of Foxtech Robotics. On the other hand, autonomous climbing robots with sensors and AI navigation (such as robot vacuum cleaners) such as those from OneMovecapable of detecting and adapting to variations in façade surfaces. In between, variants in the form of projects with hybrid platforms such as that of Skybotics Technology Limited or wired parallel systems that offer high precision, such as this from the Faculty of Engineering of Shanghai University with three degrees of freedom. Some of the technologies that can be found in this type of robots are adaptive joints to reduce wind discomfort or “zero distance” spraying to increase pressure, both present in the DJI M400one of the most popular in the sector. Yes, but. Although facade cleaning robots are a revolution for the sector, they are not a panacea: they work best on flat surfaces, they have height restrictions (typically between 60 and 120 meters for wired systems) and although they have more margin than human labor to operate in worse weather conditions, they are not infallible. Finally, the initial cost is significant, which constitutes a barrier to entry for smaller companies because it is not only the drone, it is also extra auxiliary elements such as pumping stations, batteries, software or safety certifications. For example, only the complete Lucid Bots Sherpa kit It costs $75,000.which leads to opting for solutions such as renting or leasing. In any case, and … Read more
