wheel

Ferdinand Porsche devised the first car with an electric motor in each wheel. Today a Chinese manufacturer is going to make it possible

by

Just a few days ago we were talking about Dongfeng at the Santana plant, since it will be the Dongfeng Z9, brought in pieces from China, that will end up being assembled in Linares to end up traveling Spanish roads under another name: the Santana 400. However, the brand also has a presence in Spain with the boxan urban vehicle that we have known since the end of last year. Dongfeng in China is another world, as the brand has much more impressive and innovative vehicles. One of them is the eπ 007, which has led the brand to become the first established manufacturer in the world to bring a sedan with four motors integrated into the wheels into mass production. The electric motor that is attached to each wheel What’s special about it. In-wheel motors eliminate traditional components such as the differential, drive shaft and semi-transmissions. The eπ 007 is equipped with four independent units of 100 kW each, manufactured by Shanghai Automobile Electric Drive, which add up to a combined power of 400 kW (536 HP). This architecture promises to reduce mechanical losses approximately 30% and the firm claims that it allows individual control of each wheel with torque responses in milliseconds. The advantages. According to official documentation, the system provides improvements such as a 10% to 15% smaller turning radius, 25% higher energy regeneration efficiency thanks to better braking control on all four wheels, and 20% to 30% lower maintenance costs. In addition, by eliminating the transmission tunnel, the cabin gains interior space with a completely flat floor and greater flexibility in locating the batteries. It’s not the first attempt. Although other manufacturers have attempted to market vehicles with in-wheel motors, such as the Lightyear 0 or the Lordstown Endurance, all came from startups that later went bankrupt. Dongfeng is one of China’s leading state-backed car companies, making the eπ 007 the only model to enter mass production with this technology. The vehicle will be the litmus test to find out if the invention, first devised by Ferdinand Porsche in 1900, it may end up having a commercial place, beyond concepts. The good thing is that the miniaturization of electronics over the last few decades has allowed manufacturers to opt for ideas as revolutionary and as old as including an electric motor in each wheel of the car. In the past, the problem with this system was the excess weight it brought to the vehicle. Today, Dongfeng wants to demonstrate that this idea can become viable. It remains to be seen if it will be so attractive that the general public will bet on it. More traditional versions. At the same time, Dongfeng also recently launched the updated eπ 007+, with three finishes that combine 100% electric and extended autonomy. The price started at about 139,900 yuan (about 16,788 euros). The pure electric variant is offered with a 200 kW rear motor and 650 km of CLTC range, or with a 400 kW dual motor and 565 km. Both use lithium-ferrophosphate batteries. The version with range extender combines a 1.5-liter generator with a 160 kW rear electric motor, achieving 308 km in electric mode and up to 1,308 km in total.

In his mission to follow the movements of North Korea, South Korea has decided to bet on an advanced steering wheel

by

In South Korea, the surveillance of heaven It is a constant task that is never terminated. Missile tests and the use of low flight drones The need to strengthen detection systems has highlighted by the north. Radars on land, conditioned by the country’s geography, do not always offer the necessary coverage against threats that seek to go unnoticed. To respond to that challenge, Seoul has decided to bet on a new generation of Early alert planescapable of expanding surveillance and ensuring more stable control of your airspace. It is not just about incorporating technology, but ensuring that the country has sufficient means to anticipate any scenario. The search for a new early alert plane It started in 2020when the Defense Procurement Agency (DAPA) approved the second phase of its AEW & C program. By then, South Korea already had four E-737 Peace Eye acquired from Boeing in 2006 and delivered in 2012, but the experience had made it clear that they were not enough. Parliamentary documents revealed in 2019 indicated Availability problems and technical failuress that prevented maintaining the planned patrol rate. To that limitation was added the pressure of an increasingly complex strategic environment, marked by the expansion of North Korean arsenal. A jump in the air surveillance strategy Seoul has opted for an unusual combination until a few years ago: an executive reactor Bombardier Global 6500 equipped with radar The/W-2085 developed by Elta. This system, with active electronic exploration antennas on the sides and additional sensors in the nose and tailallows to monitor in all directions promising a much greater scope than that of conventional radars. With this model, the country is looking for a more compact platform and with operational costs contained compared to larger solutions. The contest was marked by a struggle between two proposals that started from the same base plane, the 6500 global. L3Harris offered to integrate it with the radar the/W-2085, while the European Saab presented its globaleye solution, equipped with the radar Erieye Extended Range. Dapa’s evaluation concluded that there were no major differences in technical performance, but in other aspects. As the agency explainedthe American proposal received more points in operability, maintenance costs and contribution to the local industry, while the Swedish firm stood out in price and contractual conditions. Conceptual Image of Global 6500 for South Korea According to Dapa, the approved budget amounts to 3.87 billion wones, about 2,820 million dollarsand contemplates the incorporation of four planes until 2032. The goal is to have permanent patrols capable of monitoring the national airspace without interruption and coordinating the response in case of crisis. Deliver planning up to that horizon will progressively integrate aircraft in the operations of the Air Force. An E-737 Peace Eye in the United States The industrial component presumably had a relevant weight in the decision. L3harris has been supplying equipment to the South Korean armed forces, from electro-optical and infrared surveillance systems to safe communications and night vision devices. The company has an authorized service center in the country, which reduces maintenance times and simplifies logistics in case of breakdowns. The 6500 global is expected to reinforce the air defense of the Asian country. These devices will be integrated into the grid national Istarconnecting combat sensors and units to generate a complete image of airspace. Its main mission will be to detect intrusions and coordinate the immediate reaction, but its regular use is also contemplated in periods of calm to maintain training and preparation of crews.

Telefónica will have its “day D” in November. The Teleco plays its future with Murtra behind the wheel

by

Almost nine months Murtra as president of Telefónica. What lasts a pregnancy, which lasts a course. On November 4 will be born its strategic plan and Marc will have its final exam. That day will present the master lines that will define the direction of the centenary telecus for the coming years. The date is not accidental, it coincides with the results of the third quarter. Perfect occasion to combine the figures of the present with the promises of the future. And after that staging there is a company that is played much more than its next investment cycle. The scenario of the arrival to power of Murtra is, above all, a paradox: He inherited a financially sanitized telephone: Pallete reduced debt in half. But also a telephone punished by the market: the action lost 57% of its value in the previous era. The balance says the company is better. The stock market says that investors do not believe it. The market seeks growth stories, not survival. This contradiction defines the challenge of the Catalan engineer: it is not enough to be right in the accounts, we must convince those who move the silver. Speaking of silverMurtra’s great movement in his first months is the execution of The fastest exit of Latin America In the history of Telefónica. Argentina, sold. Peru, liquidated –not to say-. Colombia, more of the same. Mexico, with the “sell” poster. And at the same time, he has placed Europe at the center of his board with An aggressive discourse on consolidation. He talks about creating a “European champion” while he has in the spotlight, says the Rumore Rumoreto Vodafone Spain. With 1 & 1 in Germany in the bedroom. Is The commitment of who understands that there is no middle ground: o Telefónica grows based on acquisitions, or becomes a prey to more ambitious ones. And it has lost more than 80% of its value from its historical maximums, so it is no longer so inaccessible by price. On November 4 he will say if this strategy has a financial muscle behind or stays in speech. Local operators They have already raised the voice Against its concentration plan, Brussels has begun to leave behind its historical misgivings on mergers although the verdict remains an unknown, and the market expects to see concrete figures on where the billions that will cost these operations will come out. Murtra faces The question that defines all the great executives: Is it a visionary or a volunteer? In two months we will know.

A car rental company has fined a customer with 100 euros for smoking behind the wheel. The only problem is that he never did

by

Should you smoke inside the car? The debate is a pédiagudo and has gained strength in Spain in recent weeks after the balloon was dropped that smoking could be prohibited from the wheel in our country. The reasons wielded range from the health of the rest of the passengers (especially if the driver travels with children) to the possible distractions that a cigarette can cause. But where Smoking is prohibited It is in rental cars or in shared car services. That is what a driver has discovered to whom a company the carsharing platform Thousandsvery widespread in Berlin, has punished with 100 euros of sanction because it ensures that it briefly smoked up to four times. However, the driver alleges that this is not possible. He says not only that he has not smoked in the car, he emphasizes that he is not even a smoker. A black box for smokers The story is brought by our German companions of Gamestar Tech. They explain that, as in Spain, neither in their carsharing vehicles is allowed to smoke. To control it, cars have a small smoke detector that launches a sound warning when it records that someone inside the vehicle is smoking. According to the company, this notice rang up to four times on a three -kilometer journey that lasted 10 minutes. The driver does recognize that the detector rang but defends himself by ensuring that he is not a smoker and that, of course, he did not smoked inside the car. In your article, Gamestar Tech It shows the activity peaks registered by the smoke detector in which the four, supposed, smoke snacks that the driver expelled. The sanction on the part of the company is 100 euros but the driver says he has no intention of paying it. To try to get rid of the fine, the sanctioned contacted thousands, the carsharing company, but these were limited to showing the report with the four peaks of activity. As in the case of defective AI When reviewing the damage to a rental car, we are facing the evidence that the driver and the company are in unequal positions because one has alleged activity records and the driver has no way to prove that it is A “non -smoker”. Although the case of this driver is the last one, it is not much less unique. In social networks You can read similar complaints of other drivers who have had problems with the service of Miles, ensuring that the detector began to whistle without having reasons for it. In all testimonies a sanction is mentioned by the company of 100 euros. Some even point out that they have charged this amount up to three occasions. In the case of thousands, the detector is designed by Bosch and it is common to find them in rental vehicles. In the Consumer Information Association Austrian highlights the case of a driver who lived a similar situation. This time with a rental car and an economic punishment that reached 300 euros. The Bosch system boasts to be able to discern if a person has smoked or simply has a smell of tobacco impregnated in clothes. Therefore, I should be able to discriminate if really The driver has given or not a draft to cigarette. In addition, they claim to use artificial intelligence to send a signal to the center that manages fleets when the detector has been activated to give notice and, thus, to be able to manage the car cleaning more quickly.

The eldest war laboratory Of modern contests, the war in Ukraine, has turned drones into The fundamental piece of any offensive of both sides. Everything revolves around these armies of swarms to which it has been adding updates of all types (and times). Hence the unusual has become a rule. However, the last developments are a scoop that nobody saw coming. Evolution without humans. Ukraine has made a significant technical leap in his asymmetric war campaign by using, for the first time, Bombarder drones thrown from vessels Not surface manned (USVS), a kind of small aircraft carriers To attack key Russian facilities in Crimea. This new tactic represents a remarkable operational sophistication with respect to its first naval suicidal drones, turning these floating platforms into capable versatile systems, not only of direct attack, but also of launching multiple air attacks against strategic objectives. He most recent attackcarried out the night from July 1 to 2, 2025, destroyed three fundamental components of the long -range radar system NEBO-Messential piece in Russian defensive architecture on the Crimean Peninsula and the North -Western Black Sea. The Ukrainian Ministry of Defense described it as a “brilliant and high precision” operation, backed by A video which shows how aerial drones take off from the bow of the USVs and release several pumps with surgical impact. Operational advantages. The use of Bombarder drones From the sea it confers decisive tactical advantages. Unlike FPV previously launchedwhich require direct impact to destroy the objective, these new vehicles can attack multiple whites by mission and carry heavier ammunition. In addition, they maintain better connectivity in prolonged distances as they are not forced to descend to the ground, which allows them to operate more flexibility. Its control is mediated by satellite links (possibly via Starlink) installed in the USVs, which also act as retransmission nodes and launch platforms. This decentralized and mobile architecture complicates the work of detection, monitoring and neutralization by the Russian defenses. Russian reaction. Russian forces, aware of this evolution, have begun to observe with concern these attacks, as evidenced by the Russian military channel Two Majors. They recognize that a single Naval drone managed to approach and display multiple UAVS With load release systems, executing consecutive attacks on Russian defensive positions. Although They claim to have destroyed Subsequently, the Atacious Naval drone with air support, there is no visual tests that confirm it. The Russian reaction has focused more on request resources additional to counteract these threats that in denying its effectiveness. In any case, the incident underlines Ukraine’s ability to introduce innovations that alter tactical balance despite their resources limitations, generating psychological pressure, material wear and logistical disorder on the opposite side. NEBO-M SYSTEM NEBO-M and its tactical value. The target of this operation, the NEBO-M SYSTEMHe was not chosen at random. It is a last generation mobile radar complex introduced by Russia in 2017, designed for Detect poaching airplanesballistic missiles and aerial threats at distances greater than 600 km. The system includes The RLM-M (Three -dimensional VHF radar mounted on 8×8 truck) and The RLM-D (An Aesa radar also on mobile platform), both valued in tens of millions of dollars. These radars feed the S-300 and S-400 systems With objective acquisition data, and its location at the western tip of Crimea is vital to maintain a defensive shield on the region and access to the northwest of the Black Sea. No doubt, its neutralization opens a direct gap on that shield, facilitating the passage of long -range missiles as The Shadow Storm and Scalp-EGas well as the incursion of Kamikaze dronessignificantly weakening the Russian ability to detect and respond to attacks. Ambush and new front. In addition, in recent days another unprecedented scene occurred: the First known attack With a submersible first person drone, marking a milestone. In published images by The Northern Battalion Eagle of the 151.ª Motorized Brigade shows a river crossing in the Járkov region (previously destroyed and then improvised by the Russian forces with trunks) being achieved by an immersed explosive device. The sequence begins With a fixed intake underwater, where the FPV drone is hidden next to one end of the passage. Then, an explosion shakes the structure, destroying the crossing and confirming the effective use of the new underwater vehicle. The Shrike Special Edition. Forbes counted that, although the attack may seem anecdotal (three trunks are not a strategic objective) the real value resides in the successful use of the Shrike Special Edition, an improved version of the Ukrainian Shrike DRON FPVdesigned to operate in aquatic environments. Presented in February with the ability to land on water, dive and re -take off, the shrke was conceived as A ambush dronecapable of hiding in ponds, channels or lakes, patiently waiting for their prey. The recent attack shows that its possibilities They go further: It can destroy whites at flush or below the water level. This opens a new operating field, where air or land surveillance loses efficiency and the threat can come from the bottom of a river or a flooding area. From the suicide drone to the floating hunter. Plus: These episodes are part of a tactical progression Ukrainian that began with naval suicidal drones designed to exploit the impact, continued with the incorporation of FPV drones embarked and improvised anti -aircraft platforms, and has now led to a combined system that joins aerial and (Sub) Maritime in a reusable and coordinated way. As We count In May, Ukraine had already demonstrated the potential of its USVs when a version of the Magura V7 Armed with air-air-aim missiles AIM-9x knocked down two fighters Russians Su-30 on the Black Sea, and in December before another version (the Magura V5) he folded A MI-8 helicopter With a Missile R-73. These background reveal that the nation has managed to transform what was initially a limited deterrence tool in a multipurpose of new generation offensive platforms. New deterrence. In summary, if the twentieth century was dominated by nuclear aircraft carriers and … Read more

Huawei wants cars to drive alone in the future. So he is already devising how to hide the steering wheel

by

China wants Lead the car race of the futureand for this he will need to win in Battery developmentimplementation of own semiconductorsvehicle software and … Autonomous driving. The country led by Xi Jinping is doing Check In several of these pillars, and Huawei assumes a good part of these victories. The company has been working for years to lead technologies associated with electric cars, and autonomous driving is one of the keys that characterize it. Related to it (and related to how Huawei understands luxury in cars that have their technology), we have clues about what their future proposals will be like. A steering wheel that hides. On June 6, Shenzhen Yinwang Intelligent Technology Co., LTD (subsidiary mostly participated by Huawei) registered a design patent before the National Office of Intellectual Property of China. This application refers to a retractable steering wheel, capable of being hidden in the command post. Once hidden. The patent does not refer to the exact operation, but shows a key related to its purpose: how the seat moves back when the steering wheel folds. The possible uses. Huawei has not detailed the scenarios of use, but there is a quite clear one: that when entering and leaving the vehicle, the steering wheel folds. Although the first thing that comes to mind has to do with Autonomous driving, The objective of the patent would also be related to the gain of space in the cabin. Relaxing the autonomous driving steering wheel is possible, but reserved for a very specific group of vehicles: those that have capabilities Autonomous conduction of type L4 and L5. Currently, there is not a single car in the world with these capabilities that we can buy as private users. In China, it is reserved for robotaxis like Baidu Apollo Goor the Waymo Alphabet in the United States. Vehicles with very restricted circulation and closed fleets. What is Yinwang and what does it do. Founded in January 2024, Shenzhen Yinwang Intelligent Technology Co., LTD is a subsidiary of Huawei under its majority participation. The remaining 20% ​​is in the hands of Avat (An independent manufacturer that is sold in Huawei’s own stores in China and has Huawei Harmonyos and Technologies) and Group beings. Born to transform the Huawei Intelligent Automotive Solution (Hias) division into one of the main technology providers for electric and autonomous cars. Yinwang is responsible for manufacturing and supplying smart systems for vehicles: algorithms, sensors, integration of harmonyos adapted to automotive, control of car elements such as thermal management, suspension or braking, etc. Among his clients are brands such as Aito, Luxeed or Avat, who enjoy Huawei technologies. How house with Huawei’s strategy. Huawei’s role in the world of electric car is different from rivals such as Xiaomi. Huawei does not make electric carsdevelops the necessary technologies for China to lead them. Ren Zhengfei, founder of the company, showed his rejection of commercial terms such as “Huawei Aito”, and made it clear that his plan is to associate with different companies to provide them with their automotive solutions. At the moment, he has managed to associate with giants like Chery to provide the Luxeed S7 of autonomous parkingfight to win the career of faster electric car loaderand collaborate with Aito To provide him with his software. Patents, patents are. It is important to clarify that the registration of a patent does not have to translate into an exact materialization of the idea collected.

This 1,000 hp electric supercar is a wheel vacuum. And to demonstrate it they have put it to do the pine

by

“It is possibly one of the fastest cars that you have ever tried in curves. It is As if we had a magnet that hits the ground and allows curves to be made at speeds so unusual that even our body has to adapt. “ These are the words with which our partner Héctor Ares described the sensations transmitted by the Porsche Taycan In your first test. He described the electric car almost as one of those Scalextric cars to those who have not removed the magnet that sticks it to the raíl through which it circulates. This is because the Porsche Taycan uses what the German brand calls Porsche Active Aerodynamics (PAA)an active aerodynamic game in which the air is channeled through the low of the vehicle, is redirected where you want (brakes, for example) and next to the rear wing helps generate load. This load is the one that hits the car to the ground, which makes it especially fast in the curves. When a car has very little loadvery fast in a straight line circulates, it can reach very high speeds but In curve it is more unstable. When he has a lot of load, his advance is more difficult and needs greater power to reach the same speed. Instead, its passage through curve is very fast. In Icola, Formula 1 pilots use cars with a lot of aerodynamic load since the curves are constant. In Monza, on the contrary, cars with very little load are used because the lines are very long and the curves are relatively slow. Of course, they must fight with the famous parabolic of the end that puts a brake to convert cars into authentic rockets. But what happens when active aerodynamics is used is taken to the extreme? A car that is a vacuum cleaner To understand in a very simple way how active aerodynamics works, it is enough to observe the functioning of the DRS in Formula 1. A formula 1 car has an aerodynamic load selected by its engineers depending on the circuit in which it is going to compete. This takes into account, as we said, the curves and lines of the circuit. But when a pilot opens the DRS, the mobile part of the rear wing moves up. In this way, let more air pass, lose load (and resistance) and the car advances faster. When the pilot stops, the wing falls and has more load to pass the curve at a faster speed. Let’s say that has “more magnet” on the ground. In the 70s, active aerodynamics was prohibited in the competition but Colin Chapman took out an ace under his sleeve with the Brabham BT46b. He put a fan on his back, claiming that he served to cool the stressed engine. However, when it was launched, it generated a very strong aerodynamic load and allowed the car to a very high speed the curve. It was like a Scalextric car with a magnet. The McMurtry Spéirling putting face down That is what the McMurtry Spéirling. This electric car has become a sensation because combining the advantages of the electric car with a lightweight weight has managed to approach what we could expect from a rocket with wheels. This video in which the McMurtry Spéirling is seen removing the stickers to a Ferrari Laferrari already went viral. And it is that the electric one beats anyone because it manages to accelerate from 0 to 100 km/h in 1.4 seconds. A figure impossible to reach if it is not with an electric motor and a very deep management of traction control. It measures 3.5 meters long, 1.7 meters wide and 1.1 meters high and with its barely 1,000 kg of weight He takes out all possible performance to a 60 kWh battery. With her, she managed to get the record record to the Goodwood hill, a narrow circuit and that hinders the passage of speaking engines that need wider structures. See McMurtry Spéirling appear It is like seeing a vacuum cleaner working at full power. So much that to full performance it generates a deafening noise of 120 dB, something comparable to the take off from a plane seen 25 meters. But the truly striking, as our partners explain Motorpasion They are the 2,000 kg of load that it can generate. Given its weight content, those 2,000 kg of load allow you to make the pine. Its creators have wanted to demonstrate To what extent you can take performance to your system in a different way: sticking it to the roof. Boca down, the car generates so much aerodynamic load that can be kept without falling to the ground, only using its soil effect. He gets it because, just like Chapman’s invention in Formula 1, he has A turbine on demand. This Turbine sucks the air Under the car and stick it to the ground (in this case to the roof), which makes it keep upside down as if it had a magnet. It is the same as it costs to move more a full power vacuum than one or two degrees below. At the moment, we know that only 100 lucky ones can enjoy a car that recently beat the Top Gear circuit record in more than three seconds. A record that had Fernando Alonso’s Renault R24the car with which he ran in 2004 and that mounted a brutal v10 that also sounded spectacular … although different from this (yes, it can be said) aspirator with wheels.

AI agents are promising. But as in Tesla’s FSD, you better not take your hands from the steering wheel

by

AI agents are one of the great trends of AI This year. There are many expectations put in these models of AI capable of completing a task from beginning to end for us and almost if our intervention. And yet, one thing seems clear: for the moment it will be better “not to remove your hands from the steering wheel” and watch every step they take to prevent the AI ​​agent from being starring. Autonomy and trust. The Tesla driving assistance system –badly called Total autonomous driving (FSD For its acronym in English) – it requires that the user trust him to get carried away and that the car takes us from a point of origin to a destination without human intervention. IA agents propose a similar idea, to complete a task from beginning to end autonomously, but for this we must trust that they are able to do so. decision making. The agents will require huge data amounts and access to updated sources of information to analyze such data and then make decisions. In the past we have seen how AI models are especially good at the time of Summarize concrete information Or to draw conclusions from limited data, which is very useful for that decision making. Learn from mistakes. Tesla cars receive FSD frequent updates to improve their behavior. These updates are nourished by the data collected by the company when your FSD system is used, what allows you to polish the service. Something similar is expected to happen with AI agents, which will improve – especially at the beginning – when they are updated and “learn from their mistakes” when processing user requests. AI and companies agents. These types of solutions will be especially striking in companies that can thus automate processes that previously required total or partial human intervention. And precisely that is why this type of integration must be done in a very controlled way, because let’s admit it: we cannot trust 100% of the current AI models. Tesla knows that FSD is imperfect. It happens of course in the FSD of Tesla, which since its inception has been involved in various accidents, some of them with fatalities. One of the most recent was notified in October 2024: the low visibility made a TESLA with FSD activated a few months ago will run a pedestrian. Tesla has been criticized on numerous occasions of misleading advertising and of save the maximum on radars and sensors To achieve greater profit margin. AI agents can be equally dangerous if they are used incorrectly and “without having their hands in the steering wheel.” Users and companies that begin to use them must keep these risks very present. The hands behind the wheel, please. The conclusion was already clear in the Tesla FSD system, but also in the case of agents. They have barely done only appear on the market shyly, but everything indicates that this is one of the great trends of AI by 2025. And the problem is that the models of AI are imperfect and therefore can make mistakes, but it is that in the agents of that error it will increase. That they tell Air Canada, who had to return money to a passenger which obtained an erroneous response from the airline chatbot. Or to Chevrolet, whose chatbot was “deceived” by a user who achieved Buy one of your cars for a dollar. Domino effect. The accumulation of errors in sequential tasks is a fundamental problem in current AI models. We could say that it is something like the domino effect or the compound error: an error in an initial action distorts all subsequent decisions, generating results increasingly far from what expected. Imagine that in applications such as finance, medicine or logistics: consequences could be terrible. Solution: Constant supervision. To avoid this problem there are several proposed solutions. One of them is the establishment of check points. Thus, at the end of each subtarte the system-and ideally, a human user, what is called Human-In-The-Loop (Hitl)-should verify that everything is going well. It is also possible to minimize the risk using redundant systems – for example, using different models of AI so that the AI ​​agent uses them separately – or taking advantage of the information of the standard limits: if an intermediate fact thrown by an AI agent is too diverted from what is expected, we should rebound that process. And for the moment, spent (very) bounded. We are in a preliminary phase, and AI agents are “learning to drive alone”, so to speak. And the best way they learn is to go step by step and always starting with relatively simple and very limited scenarios. Thus, the ideal is to try to apply them to very specific cases and with a limited and known casuistry, so that their answers are as precise.

We have been trying to reinvent the wheel for years. It turns out that it was as simple as replacing it with pilates balls

by

I have always seemed curious the saying “We are not going to reinvent the wheel.” It is used when trying to develop a solution from scratch instead of taking advantage of an already proven and works well. And I say it seems curious because We have reinvented the wheel On many occasions, and we continue to do so. Two examples are wheels without air And, above all, the solutions for vehicles operating on land like Mars. Although circulars, its technology and design have nothing to do with the wheels we use daily. And, okay, I accept that, being circular, we are really changing the materials, not reinventing the object. But what if instead of making circular wheels … we made them spherical? Because that is precisely what the engineer and youtuber James Bruton has built: some omnidirectional wheels that solve current problems They have motorcycles and that would also be very interesting if they apply to vehicles such as cars and trucks. Let’s welcome the wheel II To reinvent the wheel, the system should not be just an improved version of the original. As I commented, the Antipinhazos wheels They are not a completely reinvention, but a technological improvement. What Bruton has achieved could be described as a reinvention (although he has side more than one attempt). The reason? In its motorcycle prototype of the future, we not only have the two balls that make contact with the ground, but a system of three rotary mechanisms for each wheel that are really applying the necessary force to move the balls and, therefore, the vehicle. More than the spheres, the key to the peculiar movement of this vehicle are systems that rotate in opposite directions and all the time balance each other to achieve movement. Each of these mechanisms is driven by an electric motor that transfers the power, but also introduced a self -evaluated system similar to that of a Segway. In this way, it is not necessary to rely on the floor with the legs when the vehicle stops, and it is not necessary to maintain the balance in a “manual” way. Its advantages? You can go back without boosting with your legs. It has lateral displacement. You can make diagonals and turn on your axis. For a parking lot, this is great. In the video it is very interesting to see that the noise it makes is minimal, that it reaches some speed and that the mechanisms that rotate the balls are working all the time to give speed to the vehicle and to maintain balance. Imperfect, but with potential Now, it is not perfect. In the video we can see that the youtuber has trouble going straight and There seems to be a quite pronounced difficulty curve both to go forward and to take a curve. In a road situation, it would be something really dangerous because, in addition, we do not have a conventional handlebar, but a bar that remains fixed and controls rotating the handle. There is also a time when it accelerates more of the account and the balls are shot. Wow, something like that would need your own driver’s license if applied to the real world, but if the problems were solved, it is a very interesting system for motorcycles due to automatic balance. For cars and trucks it would not be a bad idea either, since they could park much more simplely. Seeing this invention, the Audi of the movie ‘I, robot’ that has similar wheels and It was a real prototype. Also the Byd video parking in parallel Thanks to nailing the front wheels and making the rear turn slowly to “skid” until the car is aligned in the parking lot. Will we adopt wheel one day like these? Whatever happens, the truth is that it is interesting how we continue to find new ways to improve something that has implanted so many years.

The rebirth of an old system that is illuminating remote villages in India: the hydraulic wheel

by

While the big cities They have opted for self -consumption through solar panels and even wind turbinesmany remote areas of the world still fight to have a renewable system. However, in Kashmir, they have found a cheap, effective and inspired solution in the past: the hydraulic wheel. An old advance. Surely the name of the hydraulic wheel will not come a direct image to the head, but if I describe a inn away from an village in the central European area, which had a large wheel shape that spinned with the water can be more enlightening. The fact is that they were important during the industrial revolution To perform mechanical tasks such as milling or hammering. However, its use began to decrease with the expansion of burning fossil fuels and the development of electricity. However, like fashions, everything comes back, and more if the original idea was good. So with the rise of renewable energies, hydraulic wheels have resurfaced as a viable option to produce electricity in a clean and continuous way in remote and impoverished areas. A new clean source. Initial investments in renewables usually have a high cost that not everyone can afford. But what if they turn to an old energy system? That is what a group of researchers from the Technical University of Munich thought that They have managed to install A hydraulic wheel in a town of Kashmir, India. The wheel in question measures about two meters and lets the stream water pass to produce electricity. In this way, it provides an uninterrupted energy source to the community, so it does not need centralized power, which was previously a problem with frequent cuts. In addition, the hydraulic wheel is accompanied by the use of other renewable energy systems, including the Decentralized microredwhich allows the inhabitants of the people to enjoy energy independence and resilience before a possible blackout. Self -sufficient One of the highlights of the hydraulic wheel is its high efficiency, reaching the 85% energy conversion. As for the assembly cost of this system, it is relatively low, around $ 1,000, so it makes them accessible to different impoverished rural communities. In addition, the design is available on the Internet for free. Only in rural areas. Hydraulic wheels are designed for rural and remote areas, specifically in communities that need a continuous and reliable energy source. This type of system offers a simple and economical way to generate electricity without depending on fossil fuels or intermittent energy sources. In addition, its environmental impact is minimal, since they do not emit carbon and, According to studiesdamage to aquatic life is reduced. While this type of technology has limitations and is not suitable for all contexts, its potential to improve the energy self -sufficiency of small communities could make a considerable difference. More for the world. The benefits of this technology are not limited to Kashmir. A similar system has been implemented in Nepal and a prototype has been developed in Tegernsee, Germany. In addition, in Northern Ireland, a hydraulic wheel has been restored with an old mill in Fermanagh County, which now supplies electricity to a restaurant.
