There are already robots running 1,500 meters at 13 kilometers per hour. It is the result of China’s robotic muscle

by

Last weekend, Beijing hosted the first “Olympic Games” for humanoid robots. Held in the National Speed Skating Ovalthe Olympic track built for the 2022 winter jjo, the three -day event allowed the attendees to see football, table tennis, boxing, martial arts and Athletics tests. In tests and exhibitions They participated dozens of Humanoid robots belonging to both private companies from 16 countries and 280 teams from universities and, although there were more or less fun moments, which has gone around the world is that of the Unitree robot on the athletics track. We can see it in this video: In this competition, the robots were not in their air, but were being operated by humans with remote control. That does not take merit to the fact that Unitree’s H1 model I got a speed record when completing 1,500 meters in a time of 6 minutes and 34 seconds. Its speed reached 4.78 m/s, exceeding the previous 3.3 m/s mark that held a few months ago and eclipseing the 2.5 m/s that the Boston Dynamics Atlas. And, in context, although it is much slower than Jakob IngebrigstenNorwegian that has the 3: 29.63 mark, it was also faster than many non -professional humans. But what is giving what to talk about, for the “fun” of the moment, was when that same H1 he ran over an operator of another robot who, Next to the Unitree model, I had nothing to do. In the end, as the human operators run next to their robot, when they relieve the control, the H1 operators mislead for a moment and ended up overwhelming the rival. Yellow card, if they ask me. But here the interesting thing is that these Olympics for robots, more than something fun or colorful, was a muscle demonstration to the entire world. That the ‘gag’ does not prevent seeing the forest Robots such as those of Unitree have artificial intelligence systems, and even internal language models, to perform the actions for which they have been trained. H1, without going any further, has been trained with a Honor property. The ‘ruling’ in the 1,500 meters test that resulted in the outrage was due to what was commented: they were not autonomous, but controlled by an operator. However, these Olympics served to demonstrate the versatility of a new generation of robots in which many countries have interest, but that China has become a national priority. The Asian giant is following an extremely ambitious national strategy with a goal: to become a world leader in short -term humanoid robotics. With the so-called ’14th Five-Year Plan for The Robotics Industry’, the government He set goals in 2021 with the idea of annual growth of more than 20% in the robotics sector. This year the First national standards For these robots, a regulation that covers from environmental perception and movement control to the planning and execution of tasks. And, for all this, it has created a state fund of almost 140,000 million dollars for technological startups, and Unitree is one of the spoiled by the Government. HE wait that the country produces more than 10,000 humanoid robots this 2025 and even They are creating “schools” in which these machines are trained in specific tasks such as cleaning, kitchen or series manufacturing. The purpose is that they are capable of perform tasks that require fine mobility. In the “Olympics”, apart from more conventional sports tests, medication classification tournaments, material manipulation and cleaning were held. Come on, it was a window for companies to show achievements that are going to leave in all media, such as the Unitree record, but also to be seen to what extent is the specialization of these robots. China considers that these humanoid robots are “The next great technological revolution” After smartphones and electric vehicles, and are an essential tool in the industry, but also to compensate for the Demographic decrease of some countries who are suffering to find workers in certain sectors. And there are several cities in which universities and startups are investigating in humanoid robotics, but the hard core of investment and leadership in China is made up of Shanghai, Shenzhen, Beijing, Suzhou and Guangzhou, agglutinating the largest number of companies and industrial parks for the development of robotic projects. In the end, the ‘World Humanoid Robot Games’ or events such as the Robot World Football World or the Boxing championshipsThey are nothing more than a showcase to test the abilities of robots that, in China they are already living with humans. For example, the Roboperros Guide for blindthose who are “living” in the subway distributing packages to feeding stores or those who perform tasks of Hospital care and care for older people. Returning to the Olympics, the most amazing thing is that Unitree ensures that those 4.78 m/s of their H1 have already been surpassed in internal tests.

Polestar has broken a record of autonomy in electric cars circulating more than 900 kilometers. Obviously there is a trick

by

935.4 kilometers without recharging the battery. That is the record that has achieved a Polestar 3 conventional – in its version of a single engine – thus demonstrating that it is possible to make very long trips without going through a recharge point. The secret is from the record is obvious, yes. Superdespace. For achieve all those kilometers The technique was simple: go very slowly. In fact, the average speed was less than 40 km/h, and took no less than 22 hours and 57 minutes to complete the task. The publicized autonomy by Polestar for this model in its unique motor version is 706 km, so here they managed to lengthen it 32.5%. Three professional drivers. The tests were performed in the United Kingdom, where three drivers specialized in efficient driving were turned to achieve that milestone. The final consumption reached was 12.1 kWh per 100 km, which represents a saving of about 40% compared to conventional driving. Without tricks. This Polestar 3 achieved that autonomy without using special equipment: both the car and the wheels were the same as one obtains When you get the concessionaire car. However, it is possible to go further if some modifications are made. If you also have the car, you can go even further. A few days ago Chevrolet modified A WT Silverado truck and put a huge 205 kWh battery (the Polastar 3 is 111 kWh). They also placed old wheels with overpressure and 40 drivers turned to drive it around Detroit. They managed to travel 1,704 km with a single load, and as in the case of Polestar 3 the average speed did not exceed 40 km/h. The consumption on that journey was 12.7 kWh at 100 km, an equally remarkable figure in which yes, influenced that they had the air conditioning without working for almost the entire route. Baja is also worth it. In July a Lucid Air Grand Touring He got his particular Guinnes record When traveling 1,205 kilometers with a unique load. The car has a battery with the same capacity as that of the Polestar 3 (111 kWh), and toured the distance between St. Moritz and Munich. Although the car was a conventional model, the lucid benefited from both efficient driving and the energy regeneration system in braking and slopes: that route was full of them, but it was also descending mostly. The key is not the battery, they are the consumption. Although obviously the battery capacity influences the autonomy of electric cars, further influences the consumption of each model. The Mercedes Vision EQXX for example achieved a record prior to the Tour 1,010 km without recharging at 79.4 km/h on average… and another 392 kilometers had left in those conditions. The secret is that this approval model 7.4 kWh consumption at 100 km, while for example a tesla 3 rear -wheel drive homologous 13.2 kWh at 100 km. Aerodynamics helps, but if things are added to consumption as an efficient driving and low speed, those figures rise significantly. Absurd records. Although all these records are striking, they are also a marketing exercise for companies that logically try the same thing: that they talk (well) of them. Here we have messages that are also even absurd: going at 40 km/h for 23 hours has its reward in this case, but in real life it would be absolute torture. The practical uselessness of these records – not only that of Polestar – is the same as the one who tells us about how The Xiaomi Su7 beat all its competitors In Nürburgring last year: none of us are going to those speeds or drive in those circuits, but speed records are always striking. Putting these vehicles to the limit is fine, but it is important to contemplate these records with perspective.

Chrysalis, the impossible ship 58 kilometers long to transport 2,400 people to next Centauri

by

Exodus through space is a recurring theme in science fiction. It doesn’t matter if it’s literature (‘Aurora’), cinema (‘Wall-e‘) or video games (‘Mass Effect Andromeda‘), the idea of a huge ship that transport a lot of people that become inhabitants of a planet on the other side of the universe is as fascinating as utopian. But at some point you will have to get to work, and there are those who have had an idea: a 58 -kilometer ship for Bring Humanity to Alpha Centauri. His name is Chrysalis, and the duration of the trip will be 400 years. Chrysalis project. Within the ‘Project Hyperion Design Competition‘, a group of Italian social engineers, scientists and architects They have designed Chrysalisa ship of about 58 kilometers in length with a cylindrical and multicapa architecture. To simplify, it would be like a Russian, but elongated doll, with a concentric core and layers that would have differentiated areas for: Production. Life. Industry. Storage. Would have artificial gravity achieved by constant rotation of the entire cylinder and the idea is that it can transport 2,400 passengers to Next bthe most promising exoplanet of the system. There they would disembark and could start colonizing the territory after a 400 -year trip. Estimated construction time? 20 to 25 years. Layers. It would be like a huge city and remember The Line, the Saudi Arabia macroproject. Throughout those 58 kilometers and depending on the layer, areas destined for food production, forest biocservation, community areas with parks and facilities such as schools, hospitals or libraries, as well as habitable modules, industrial areas and an external ring dedicated to storage. The heaviest jobs would be operated by robotsand it will not be the only thing, since the plan includes a combined governance between humans and artificial intelligence. No cryogenization. Something that we usually see in these science fiction works is that the crew criotic so as not to die during the trip, but in the case of Chrysalis, there would be no option. Throughout those 400 years, several generations will pass, being a task for all those that fail to reach the goal. To avoid tensions due to the shortage of resources, births would be controlled to the millimeter, maintaining the population within the sustainable limit that the installation can provide. Recycling is contemplated as a vital option and, to give energy to the entire complex, nuclear fusion reactors will be used. Crew preparation. In addition to the fact that everyone who embark on Chrysalis will not see their new home on the mainland, it must be taken into account that virtually no one of those who embark on the mission at first will set foot on the ship. The reason is that it is estimated that one of the most crucial part of the trip, also the most radical, will be the preparation for it. In addition to having psychological support and having a careful strategy for 2,400 people to live in such an environment, before leaving the training will be given for 70 or 80 years In Antarctica. That first (and almost second) generation will face the conditions of isolation and extreme confinement that they will experience during the journey. It will be part of the second and third generation that, finally, are on their way to next Centauri b. Housing modules. There would be one and two floors Do not make illusions. Now, the ‘Project Hyperion Design Competition’ is an initiative with an objective: to seek a spacecraft capable of taking some thousands of humans to a habitable exoplanet In an interstellar trip of several centuries, so it is only a conceptual project for several reasons. The first could be ethical, since training will be devastating and, in essence, the entire trip is an evolutionary experiment with a large -scale controlled population, which means this Mental health levelidentity and perception of time. The second … because the technology to make it reality escapes our understanding right now. Only the fact of need Fusion reactors (that We are investigatingbut we have not yet developed), leave this experiment as something exclusive to the science fiction field. Although, yes, The document It is tremendously explained. Images | Canva (presentation of the project) In Xataka | It was not an extraterrestrial ship, but not a giant kite.

There are thousands of people hooked to streaming. One to 3,900 kilometers deep full of marine curiosities (and memes)

by

In the Submarine Canyon of the Sea of La Plata, near Argentina, something of the most curious happens: two powerful currents coincide. One is salty and warm. The other, cold and very rich in nutrients. The union of both is the Confluence Brazil-Malvinas And it is important in the Earth’s climate regulation. It is known that there is a huge ecosystem down there, one of which little is known and that, at the moment, it is being explored live by an underwater rov next to thousands of people who, since July 23, They follow their live emissions Through YouTube. The mission. These submarine cannons hide a varied species ecosystem in their recesses. In 2012 and 2013, the Continental I, II and III of CONICET expeditions (National Council for Scientific and Technical Research of Argentina) used fishing and drag networks to explore the bed, discovering new species and leading to the publication of more than 60 Papers. Now, in 2025, technology has improved and It is possible to explore depths up to 3,900 meters with a vehicle operated remotely. Continental slope IV: Underwater Oases of Mar del Plata Canyon. That is the name of this new mission, an expedition of CONICET in collaboration with the Schmidt Ocean Institute. As explained from the Council, “it is the first time that in the Argentine Aguas of the Southwestern Atlantic the remotely operated vehicle (Rov) is used, capable of capturing underwater images in ultra high definition and collecting samples without altering the environment.” The funny thing is that the adventures of this rov They are broadcast live through YouTube. The goal. In addition to studying the Argentine seabed as it has not been possible to generate 3D models of emblematic species to produce educational material. The one who has interest can access the data collected completely free through open repositories such as CONICET Digital, Bish and Genbank. Image | CONICET How is the thing going? According to Explain The CONICET researcher in the MACN and scientific chief of the expedition, Daniel Lauretta, “we are barely starting and we see incredible things: animals that had never registered in this area, underwater landscapes that seem from another planet, and behaviors that surprise even the most experienced scientists.” It also states that being able to broadcast it live makes “science is somewhat distant or inaccessible, and becomes part of the day to day. In addition, it forces us to explain what we do clearly, without turns, so that anyone can understand and enjoy it.” The memes. That streaming has become so popular, has undoubtedly helped the collective ingenuity when seeing comedy in the seabed. It is an unknown territory for most and the species that live there are striking. That is why it is not surprising that networks like X have been filled with captures, memes and funny texts with these species as protagonists. The capture of that sea star has gone around the world, but it is not the only one. As for whatever, users have baptized it as “Estrella Culona” | Image: Xataka Argentina Caught in fraganti | Image: Xataka Argentina A violet benthodytes. His nickname: Batatita | Image: Xataka Argentina “Me and the boys together to see a stream of the CONICET,” says an X user | Image: @Genaro23101 Jokes apart, why there? The Malvinas current moves north from Antarctica to almost Río de la Plata, dragging cold and nutrient rich from Antarctica to the Patagonian platform. This current is very important for Argentina and its fishing industry, valued at 2,000 million dollars According to Schmidt Ocean Institute. The current of Brazil, more superficial (700 meters or less), transports warm and salted water from Ecuador to Rio de la Plata. Where both currents collide a strong thermoclin that, in turn, and due to temperature differences, generates rotating currents that redistribute heat, helping to regulate the climate of the earth. As explained by the institute, “the mixture of these two mass of water so different probably creates conditions that facilitate the coexistence of temperate and tropical organisms, as well as species that can only be found in the confluence.” Hence this area has so much scientific interest.

27 kilometers under the sea to avoid fjords

by

Norway has underway A series of megaconstructions that aim to beat numerous records. It is not for less, because it is a country with a very particular geography in which certain types of infrastructure are necessary to opt for certain comforts. One of the most surprising is undoubtedly Rogfast, a four -lane submarine tunnel that will connect the districts of Randaberg and Bokn through 27 kilometers under the sea. This megaobra promises to revolutionize transport on the Norway west coast and drastically reduce travel times on one of the most traveled routes in the country. Fjords don’t make it easy. The E39 coastal road, which travels 1,100 kilometers from Trondheim to Kristiansand, is interrupted seven times by fjords that force Ferris. This turns a direct journey into a 21 -hour odyssey. Rogfast will eliminate one of these interruptions and will cut 11 hours of the total tripbenefiting millions of people who move to the cities of Stavanger and Bergen. Record figures. The tunnel will reach a maximum depth of 400 meters below sea level and extended 27 kilometers, officially becoming The longest road submarine tunnel in the world. It will surpass the current record, the Norwegian Lærdal tunnel of 24.5 kilometers, which crosses mountains but does not go under the sea. Turning Rogfast will take approximately 35 minutes and will have an underground roundabout at 250 meters deep to give access to Kvitsøy island. Image: Telegraph A technical and economical challenge. The works began in 2018 with an initial budget of about 1,838 million euros, although experts estimate that the total cost of modernizing the entire E39 could reach more than 40,000 million euros. The Norwegian government will finance 40% of the projectwhile the rest will recover through a toll of about 34 euros per use. The construction suffered several delays, especially during the pandemic, but maintains its scheduled completion date for 2033. Beyond travel cutting. Engineers have designed a special artistic project to combat monotony and anxiety that a tunnel can cause so extensive. The system promises to include dynamic lighting and decorative elements that will create a sensation of orientation and make the underground path more bearable. The idea is that drivers perceive travel time as shorter than it really is. Goodbye Ferris. Rogfast is part of a larger plan to completely eliminate the Ferris of the E39 and connect the entire Norway west coast with fixed infrastructure. Some sections will require “floating” tunnels anchored to the seabed due to the excessive depth of certain fjords. If the project is successful, Norway will have shown that it is possible to create a completely terrestrial coastal highway in one of the most challenging geographic territories in the world.

More than 18,000 kilometers between Portugal and Singapore without the need for CAM

by

Trains lover, we have your plan for summer. It is very possible that we are late but as you will see it is better to prepare it with time, carefully and, above all, asking for all the necessary permits that you will need. Because yes, you will need them. Permits, about 1,200 euros and time. Three weeks, specifically. It is what is needed to cover the railway line that, linking trains and companies, allows all of Europe and much of Asia to reach its southern end. With departure in Laos (Portugal) and arrival in Singapore, we talk about the longest train trip in the world. This is the world’s longest train trip It all depends on how much money we want Euronews than the longest train trip in the world You can take about 1,200 euros and 21 days of journey, taking into account some breaks in the city to rest or the time to be used in visas. At least that was the estimate in 2021, the year in which the Opening of a new section Railway between Kunming (China) and Votián (Laos) allowed to add the kilometers enough for the line to end in Singapore. The change is so relevant that it allowed to reach 18,755 kilometers to which the total journey amounts to. At that time, Russia had not yet decided to invade Ukraine so the trip has been complicated since then. The idea is to enter Russia prior to Germany, Poland and Belarus so communication should be assured. Of course, we should not lose sight that whoever is determined to carry out this railway odyssey is entering a country at war. To have all the details by hand, in the SUBDDIT R/MAPPORN They have drawn The whole route exposed on a map of Europe and Asia. In it we see how the route begins as we said in Laos (Portugal) at the southern end of our continent. Next to the Algarve begins an adventure that can end in another paradisiac environment, the Best Singapore Beaches. Following the proposal of Reddit users forces to put Madrid aside and choose to cross all of Castilla y León. From there, one goes to the Basque Country and crosses France for Perpignan. Once in the Gallic country, European capitals will be linked: Paris, Berlin, Warsaw, Minsk and, already in Russia, Moscow. Once in Russia is the longest section of the trip within the same country. Overcome Moscow, it continues a little further north taking two of the most famous lines that make up the trip. First, much of the route of the Transiberiancrossing the entire Russian steppe but before reaching the end it is about deviating to Mongolia. Entering Mongolia in the north, now another famous train is taken, the Transongolianwhich serves as a railroad between Moscow and Beijing. Here, we cross the Chinese border that we will only leave behind when we travel south. It is time to return to Laos (this time phonetically), Thailand and Malaysia. Chinese influence is notable here, even after having overcome the borders of the country since if we are traveling through train, it is because China built the line that UNE Bangkok with Beijing. It is, in fact, Laos’s first railway line that does not end in the sea. Overcome the almost 19,000 kilometers of train is time to enjoy the destination. Relax and, why not, try to imitate Willy Fog. If Smith’s estimates do not fail, we have half the world to go and 59 days ahead to match the feat of the character of Julio Verne.

We have just measured the longest ray ever registered on Earth: 829 kilometers D

by

The rays are huge electrical discharges that in a fraction of second run through the distance between the clouds and the surface of the earth, a distance that can be several kilometers. However, lightning can go to distances a pair of superior magnitude orders. And this is one of those cases. The longest ray. The World Meteorological Organization has confirmed The longest ray observation ever registered. The electric shock toured a distance of 829 kilometers, with a margin of error of about 8 km. To put it in perspective, that is approximately the distance that separates in a straight line Barcelona from Seville. Although the validation by the United Nations Meteorological Office arrived this Thursday, the event occurred almost eight years ago, In October 2017in the United States. The great plains. The ray with its ramifications reached the skies of five states in the central and southern United States. The beginning of his “route” was on the east of the state of Texas, and his end was close to Kansas City, in Missouri. His tour and ramifications also made him pass through the states of Arkansasa, Kansas and Oklahoma. The region of the great plains where lightning was also known as Tornado Alleythe “Alley of Tornados”. This area, the OMM points out, stands out for being one of the areas “with the greatest storm activity known as Mesoescala convective systems”, which also makes it an ideal area for the formation of these “megarrayos.” For 61 km. As explained by the OMM, the new record exceeds 61 km the previous record. That ray also happened in the United States, but later, in April 2020, and reached 768 km, also with a margin of error of 8 km. In both cases, the detection and measurement of these rays was carried out through a method called Maximum Circle Arch. In addition, the OMM emphasizes that the 2017 ray was one of the first events measured with the help of the operational geostationary satellite for the study of the environment of the R (GOES-16) of the NOAA (National Oceanic and Atmospheric Administration). They also explain that this “megary” went unnoticed in a first analysis of the storm, and was not discovered until the review of the data compiled during the stormy episode. Now the details of the analysis carried out by the OMM team have been published In a working document of the Bulletin of the American Meteorological Society. Improving prevention. The study of the rays goes beyond establishing records that feed our curiosity about these violent phenomena. Improving our study tools and knowing these events better is key to reducing the risk they imply in several contexts, from aviation to forest fires. “Rays, although they are a source of astonishment, also constitute a great danger that is charged numerous lives every year worldwide, which makes these phenomena one of the priorities of the international initiative an early warns for all,” pointed in a press release Celeste Saulo, general secretary of the OMM. “This record highlights important issues for public security with respect to electrified clouds, (…) that may have serious repercussions on the aviation sector, as well as cause forest fires.” Carrying the accounts. The OMM is the institution in charge of Register extreme atmospheric events Throughout the world, an archive that has other records protected by great magnitude rays. For examplethe lightest ray registered lasted no less than 17 seconds (17,102 ± 0.002 s, specifically), and was captured in Argentina in June 2020. The direct impact of greater size was recorded in 1975 in Zimbabwe, and cost the lives of 21 people. However, the greatest indirect impact occurred in 1994, in Dronka (Egypt), and resulted in 469 people deceased when causing the fire of oil deposits.

Drones have become the great threat of Ukraine. So you are covering kilometers of roads with nets

by

Neither tanks nor mines nor sophisticated fighters. What really removes the dream of the soldiers who fight in the Ukraine War (and it is a feeling shared by both sides) are The dronesunmanned aerial vehicles (UAV) loaded with explosives. So much so that the military have baptized the 10 km strip that extends to each side of the front as “Zone of Death”an area infested with remote piloted drones and that can neutralize their objectives with a much lower investment than would require a similar missile. The UAV play such an important role in the war that a curious picture is left: kilometers and more kilometers of road protected with networks. A landscape covered with networks. To complicated problems, imaginative solutions. The France-Presse (AFP) agency has published A chronicle in which he tells how the war between Ukraine and Russia is having a curious effect on the wide range of the front: it is covering it with networks. Networks and more green networks that are installed on post -high posts along kilometers of road in the region of Donetskone of the great stages of war. AFP recounts how Ukrainians are riding that vast tangle of networks to cover their main supply routes, but the panorama is not very different on the other side of the front. The Russians have also set to work to perform a similar task. “Let’s weave nets, just like spiders! We do it for birds without extremely dangerous feathers,” Ironiza In April a nicknamed ‘Ares’. But what birds are those? Drones Drones swarms, surveillance vehicles, kamikazes or equipped with explosives that suppose a serious threat to soldiers and civilians. With meshes the military seeks to repel them in a seemingly as simple as effective way. “When a drone impacts the network, a short circuit occurs and cannot attack vehicles,” Explain To the French agency Denis, a commander of the 27 -year -old engineers. The initiative is not entirely new. A few months ago We told you Already how Ukraine was taking advantage of tons of old Danish fishing networks to repel Russian drones. Now already measure that the Ukraine War is on its way to turning three and a half its use seems to be extending on the front. In March a small sailor town of Jutlandia, Thyborøn, It was news precisely by donating 450 tons of drag networks made of nylon fibers. In origin, meshes were thought to capture tons of fish, but they have also been useful to keep drones away from strategic objectives, especially as the expanding the Fiber optic modelscapable of making fun of devices that cut the connection with the pilots. The drone war. It may seem exaggerated, but if for something the Ukraine War is highlighting, it is precisely because of the role that drones and the threat they represent for soldiers. Reuters cites today Internal reports of kyiv that confirm that the UAV already represent about 69% of the attacks against Russian troops. Moreover, in 2024 they were behind 75% of the attacks undertaken against vehicles and equipment. They are percentages that far exceed those of the use of conventional artillery, which move between 15 and 18%. The great threat. Reuters cites a squad commander, Ivan, 35, who Openly recognize That the soldiers of both sides see the unmanned aerial vehicles already as the main threat to their lives. Your swarms too They take away the dream In the cities, kilometers away from the front. Yesterday Russia launched An attack against Dobropillia as part of an offensive that included the use of hundreds of drones. His role is so relevant that Mark Boris Andrijanic, Slovenian politician, has published An analysis in which it slides that an increase in drones financed by the West would allow war.

Some scientists have rowed 225 kilometers in 45 hours between Taiwan and Japan. It seems absurd but there are good reasons

by

In 1947 the Norwegian explorer and ethnographer Thor Heyerdahl He had an idea To demonstrate that the former inhabitants of Peru were able to navigate to the coasts of Polynesia in pre -Columbian times: to manufacture a rudimentary raft and cover the journey himself. Sounds crazy, but experience went well and seems to have created school, like He has just demonstrated An anthropologist determined to reveal how humans were managed to travel between the coasts of Taiwan and the islands of southern Japan. Along with the rest of his colleagues he has chosen to follow the footsteps of Heyerdahl, manufacture a cedar canoe with tools from the Paleolithic and then launch to the Pacific waters. When, where … and how. Researchers who are dedicated to studying the first human settlements in East Asia have a rather accurate idea of ​​when and where the first migrations were made, but there is a question that still takes away their dream: how noses they moved? How did they travel through sea, raffling waves, winds and currents, with hardly any resources? How did the first settlers manage to arrive for example do 30,000 yearsTo the island Yonaguniin the archipelago of The Ryūkyūcurrent Japan? After all, Taiwan is more than 100 kilometers and the distance is even higher from the continent. “Simple questions”. That kind of questions are what the anthropologist was asked a few years ago Yousuke Kaifufrom the University of Tokyo. During his investigations in the deposits of the Okinawa Islands he found vestiges that give away that there were already humans in the region 30,000 yearsbut nothing that clarifies how they got there. “There are stone tools and archaeological remains, but they do not answer those questions,” confesses to The Guardian. That there were no evidence did not mean that Kaifu and his colleagues could not raise hypotheses … and demonstrate them. “We started this project with simple questions: ‘How did the Paleolithic peoples arrive at islands as remote as Okinawa?’ ‘How was your trip difficult?’ ‘What tools and strategies did they use?’ ” remember The Japanese anthropologist. “Archaeological evidence, such as vestiges and artifacts, does not offer a complete vision, since the sea, by nature, drags them. So we turn to experimental archeology, in a line similar to The Kon-Tiki expedition of 1947 of the Norwegian Thor Heyerdahl “. In the skin of the ancestors. Like Hayerdahl and his mythical expedition Kon-Tiki, Kaifu and his colleagues assumed the complicated task of putting themselves into the skin of their ancestors of thousands of years ago. How did they travel? How did they guide themselves? What materials did they use for their vessels to draw the currents of the region? First they tested with Juncos balsas and bamboo, but ended up ruling out the idea. With these materials they obtained too slow ships to overcome The Kuroshioone of the strongest sea currents and that conditions navigation in the northwestern Pacific. His next option was to try a canoe made with Japanese cedar, such as those used in the area thousands of years ago. In order for the experiment to be as faithful as possible to reality, the researchers talled a cedar one meter thick with stone axes and then carved it until opening a cavity inside and giving the shape of a canoe of 7.5 meters of length. The result was ‘sugime’, a boat not very different from those used thousands of years ago. In 2019, after waiting for the sea to calm down, a team of five crew (in which scientists and remakes were included) rose on board and tried it. And how did they do it? As the Paleolithic men, without GPS or any other modern navigation device, would have done only by the stars, the sun, waves and instinct. The expedition started from Taiwan Rumbo Yonaguni, in Kyūshū. The island is not visible from the Taiwanese coast (and in fact it was not for much of the journey, when it was hidden from the waves), but the scientists verified that on clear days it is not difficult to contemplate it from the mountains of Taiwan. Hence the populations of 30,000 years ago they met her. The raft left in July 2019 and its crew had to row more than 45 hours and cover a journey of 225 kilometers before reaching its destination. It was not easy, but the team reached Yonaguni to the second night, reinforcing the theory that thousands of years ago the first Okinawa settlers were able to travel in Canoas from neighboring Taiwan. During the syglura, yes, They suffered crampspain and hallucinations and even were forced to Browse water Often to prevent the raft from getting causing. “They achieved something extraordinary”. The experiment was completed in July 2019 thanks to the support of several institutions but has not achieved authentic impact so far, when the University of Tokyo He has revealed The experience. The reason? A few days ago there was a documentary about the trip and two academic articles published in Science Advances. In one the experts report the 45 -hour experiment between Taiwan and the island of Yonaguni. In the other they share virtual recreations hundreds of possible routes to know which could be the “most plausible”. “The general public usually considers the Peoples of the Paleolithic as ‘lower’, mainly due to their ‘primitive’” culture and technology, ” collect the report. “In marked contrast, our experiment has shown that they achieved something extraordinary with the rudimentary technology they had.” The experiment also confirms the growing interest in archaeological reconstructions and tests with boats that copy old models, something that (in addition to the case of Hayerdahl) we have seen in Indonesian research, France either United Arab Emirates.

Byd has shown us that the 400 kilometers load in five minutes is very real. And they have managed to change their minds

Designed for heavy but practical transport for the daily car. And an advance that has raised some controversy in the battle that China-Occident in the battle for the electric car. It is the 1 MW charger of byd. The same one that, they promise, can load 400 kilometers of autonomy in five minutes and with which, in the words of Stella Li (vice president of the company) equals “the experience of Fill a deposit of gasoline “. It is definitely one of the advances in the electric car that has raised the most interest in recent months. And in Xataka we have tried it. Yes, it is very real In a concessionaire and next to other lesser power chargers. Byd has shown us the operation and recharge of its 1,000 kW or 1 MW charger. An experience that promises to match the times of gasoline but that, they assure from the company, is not primarily thought for cars. Last March, Byd hit the table showing your most powerful loaders to date. Immediately, domino’s chips fell and we knew that Catl and Huawei also confirmed that had ready their own ultra -grape load suppliers. The race for the electric car in China advances at a devilish pace that has taken us at the end of this June, just over two months later from the announcement, to see these loaders in operation. The expansion of the more than 4,000 points that the brand aspires to have very soon in its country clashes frontally with the slowness in Spanish facilities. Be that as it is, the truth is that two byd cars can now recharge in this type of facilities. They are the byd and tang l, two electric mounted on their super e-platform that can assume the power of its megawatt flash charger, a load point known as the 1,000-1,000-1,000: 1,000 kW, 1,000 amps and 1,000 volts. A BYD TANG L at the 1MW load station And that’s what we saw. First with a Byd Tang L and, later, with a Byd have l, the company showed us the system load capacity. For this it is necessary to plug the two hoses that leave the supplier. The car, like a Porsche Macan, has two load shots (one on each side) and plug at the same time. Once the two shots are connected, the load begins from the vehicle. And magic happens. In two minutes, 7% battery capacity has passed to almost 40% of it. One is hypnotized When you see on the central screen the 1,000 kW of load power and the percentage of the battery upload. The maximum peak does not last too much. But that is not too much problem. After 20%, the power falls to 750 kW and it remains so until 30%. It is not then that it is maintained with sufficiency in 700 kW or slightly below. Thus it will come with hardly any drop to 80%. At that pace, moving from a brief 7% to 80% autonomy leads to, just over five minutes. And that 80%, In a car with 83.2 kWh Battery are about 67 kWh available. To lower the data to the ground, two questions. Is it a lot of power? It is a lot of power. It is a barbarity. To get an idea, the most powerful load points that are in Spain Sinde 350 kW and begin to consider loads of 500 kW. Have a car that carries, when the power drops, at 700 kW is to fold the most advanced vehicles at the moment, from the Porsche Taycan and Audi GT e-tron to the KIA EV6 and Hyundai ioniq 5. Just a handful get these figures in Europe. Really load 400 kilometers in five minutes? Yes and no. We explain ourselves. The 67 kWh that would have available any of these two cars with 80% load equals just under 350 real kilometers with a consumption of 20 kWh/100 kilometers. If you talk about 400 kilometers in five minutes it is because the Chinese homologation system is much more lax than WLTP. This has led us to receive news from China from cars with 1,000 kilometers of autonomy that would not support an exam in Europe. Despite this, we must not crucify how to measure in the Asian country. You have to take into account the peculiarities of each market. The homologations are assumed, both the Chinese and the European WLTP try to simulate the use that an average driver would give it. That in China, where the car is used as a ciudad already low speed (also in the ringms) it is much more likely that the average consumption is lower than for a European driver. It is something that have confirmed different Chinese brands: the car is for urban use, for the long trips bullet trains and airplanes are used. Is it really practical? When Byd gave the news, the competitors soon answered. As we have seen, Catl and Huawei came out to point out that they also had similar widths for imminent expansion. From Europe the message was another: That loading power is useless. That was what they pointed out in Mercedes. An opinion that can be controversial and shared before going to China. Now, I thought things better. What they maintain in Mercedes is that so much power is not necessary because, generally, when we stop we are standing for more than five minutes. And it doesn’t matter if we are going to have coffee or, simply, fill the car deposit. In the latter we spend more time of five minutes. If we are barely stopped 10 minutes, it recharges it with a car that can fill its batteries at 350 kW of power does not change much with respect to Byd’s proposal. And, if this power is supported, in just 10 minutes almost 60 kWh capacity will have been filled. That is, 300 kilometers with the previous calculations. In practice, the difference is not much.
