There is a physical limit to what a cell phone camera can do. OPPO is pushing that limit further than anyone else

May 7, 2026 by usatoday24

Standing out in the mobile showcase is a war that is fought on many fronts at the same time and mobile photography is the most decisive, especially when we enter the super high range with mobile phones that easily exceed 1,000 euros. Until recently, the fight was between the iPhone, the Pixel and the current Galaxy, but things have changed a lot and Chinese companies have advanced to the right. One of those companies is OPPO with its OPPO Find X9 Ultraone of those who is undoubtedly a candidate for the throne of mobile photography. We were in China for the launch of its new flagship, where we were able to visit its new campus in Shenzhen and speak with Jie Liu, Senior Imaging Product Manager at OPPO, who told us more details about the camera. Taking good photos is no longer enough, we want versatility We are at a point where any mobile phone in this price range takes excellent photos. Quality is presupposed, that’s why the battle has shifted to versatility: offer from an ultra wide angle to a superzoom, maintaining uniform quality throughout the range. The OPPO Find X9 Ultra has a 200 megapixel main sensor that allows us, through cropping, to simulate a 2x zoom. It is accompanied by a telephoto lens of another 200 megapixels that is equivalent to a 3x zoom and, again, by cropping it allows us to simulate a 6x. And the big news: a third 50 megapixel sensor equivalent to a 10x optical zoom or 230 millimeters. Of course you can’t miss the ultra wide angle (0.6x), which also in this generation increases the size of the sensor to improve quality. Left: 1x main sensor. Right: 10x telephoto One of the things that caught our attention is how they have integrated a telephoto with that focal length into the body of a mobile phone since, although the camera module protrudes quite a bit from the chassis, it is still not enough for such a long zoom. Jie told us that “to make the module small enough we used a telescope structure, with a new technology called quintuple reflection. This configuration reduces the physical length of the system while maintaining the focal length.” This is the structure of the 10x telephoto. Image: OPPO It is a structure of different prisms that reflects light five times until it reaches the sensor. The problem with this is that the light must travel a longer distance, which results in images with more noise and lower luminosity (the aperture is equivalent to f/3.5). “We have used technologies to reduce the noise caused by these multiple reflections, such as a layer of air between the prisms that reduces noise and loss.” The Teleconverter Claim OPPO has already started the path of teleconverters with the OPPO Find X9 Pro and raise the bar with the Ultra model. This is a photography kit that is sold separately and includes a 300 millimeter objective which attaches to the mobile phone thanks to a special case that also has a handle. It is a strategy copied from the one that Vivo has followed, first with the Vivo X300 Pro and then with him Vivo X300 Ultra (both companies belong to the same parent company, BBK Electronics). When we attach the teleconverter, we can take spectacular photos from very far away, with stunning bokeh that we can only achieve with a lens of these characteristics. This lens is attached to the 200 megapixel telephoto lens, so we can do the cropping “trick” again to achieve a 30x zoom, equivalent to 690 millimeters. The results speak for themselves: Photo with the teleconverter at 690mm or 30x At the moment, OPPO has launched two teleconverters, 200 millimeters in the Pro model and 300 millimeters in the Ultra, two fixed focals. The problem is that they only work with the model with which they were launched, meaning that we cannot use the 200 millimeter teleconverter of the Pro in the Ultra. During the meeting, we asked Jie Liu if the brand has considered launching more lenses in order to expand the range of available focal lengths, and even if there is the possibility of launching a lens with a variable focal length, for example a 200-400 millimeters: “It is a good suggestion and it is our direction of evolution, but this entails many technical obstacles. The solution we have now is temporary to ensure image quality, adding new focal lengths is a consideration for the future.” Teleconverter 300 mm or 13x OPPO wants to replicate in a mobile phone the focal versatility that any camera user takes for granted. The problem is that, although they have managed to integrate a 10x telephoto, the chassis of a phone has physical limits and there comes a point where no more optics can fit inside; andThe natural step is to complement with accessories. While its competition continues to depend exclusively on the integrated sensor, OPPO is already building that ecosystem, although still quite timidly. The photographic kit works more as an attraction, a “look what we know how to do”, and not so much as an accessory for the general public. The OPPO Find look what we know how to doand not so much as an accessory for the general public. The soul of photography Until recently, many Chinese phones suffered from overly aggressive and artificial image processing, but that is changing. One of the things I liked most about the OPPO Find X9 Ultra camera is the image processing, quite natural and realistic in general. Of course, there is AI processing, but Jie told us that it is applied in a controlled manner “always seeking coherent aesthetic results. It is applied to correct unfavorable lighting conditions, reducing artifacts and noise, improving exposure and dynamic range in complex situations.” AI is also used to improve the results of the 10x zoom “to optimize detail and stability.” Portraits are incredible, even at night (taken with 200MP telephoto, 6x). … Read more

China has been pushing the boundaries of engineering for years. Its gigantic high-speed tunnel boring machine has just given another example

March 31, 2026 by usatoday24

China has been developing large infrastructures and its own machinery to execute them for years, with projects that tend to stand out for their size and the technical control they require. It is not just about building more, but about doing so under increasingly demanding conditions. This pattern is repeated in very different areas, from energy to scientific research, and also in transport infrastructure. Under this logic, the appearance of new machines and projects is not an exception, but rather the continuation of a clear trend that now adds a new chapter with the “Linghang” tunnel boring machine. The advance. “Linghang” has completed the section under the Yangtze Riverwith a continuous excavation of just over 11 kilometers, according to CCTV. The machine began its journey on April 29, 2024 from Chongming Island, in Shanghai, and after 23 months of work, it completed the underwater section of the river, surpassed the south dam and came ashore in Taicang, in Jiangsu province. The movement is not minor: it involves completing the section under the watercourse, one of the key points of the work, and leaving the project one step away from its next milestone. What’s behind. The operation is integrated into the tunnel Chongming-Taicanga key work within the Shanghai-Nanjing section of the Shanghai-Chongqing-Chengdu high-speed corridor. With a total length of 14.25 kilometers, this infrastructure brings together several technical milestones, including the world’s longest single head excavation distance in a high-speed tunnel, with 11.32 kilometers, and a maximum depth of 89 meters under the Yangtze. The design contemplates the passage of trains at 350 km/h even in the underground section. The machine inside. The tunnel boring machine used in this project has unusual dimensions even within this type of work: it measures about 148 meters in length and weighs around 4,000 tons. according to Global Times. It is equipped with an intelligent control system called I-TBM, designed to automatically manage a large part of the excavation process, from internal pressure to the forward position or the exit of the material. Added to this are elements such as high-pressure seals, a long-lasting main bearing and a cutting head prepared to withstand demanding conditions under the river. A project that is not an isolated case. In recent years, the country has built facilities such as the Three Gorges Dam, the FAST telescope either the EAST reactorprojects that, although they belong to different areas, share the same base: scale, technical control and own development. In this context, this type of machinery is best understood not as a specific milestone, but as one more piece within a sustained line of work. A close reference. In Spain, the Mayrit tunnel boring machine, currently in use in the expansion of line 11 of the Madrid Metrooffers a useful point of comparison to understand the magnitude of this type of machinery. Measuring about 98 meters in length, weighing around 1,500 tons and with a diameter close to 9 meters, it is a large piece of equipment within the European context.

The artificial intelligence race is pushing the US towards an unexpected energy solution: looking to the military sphere

December 27, 2025 by usatoday24

The artificial intelligence race is not only being fought in laboratories, chips or data centers, it is increasingly being played in the field of energy. In the United States, the accelerated growth of electrical demand associated with AI has exposed a barely visible fragility: the network is not expanding at the same pace as technological ambitions. This imbalance is forcing us to look beyond conventional solutions and reopen debates that seemed closed, including some that connect directly with the military sphere. What has been put on the table. HGP has submitted an application formal to the United States Department of Energy to redirect two nuclear reactors removed from Navy ships to a civil project linked to data centers in Oak Ridge, Tennessee. The request was channeled through a letter addressed to the Department’s own Office of Energy Dominance Financing, and is part of the so-called Genesis Mission promoted from the White House. According to the documentation, the installation could provide between 450 and 520 megawatts of continuous electricity, aimed at intensive and stable consumption. The main argument in favor of this idea is time. Faced with the construction of new civil reactors, whether large plants or smaller designs, which tend to move on long schedules, or the start-up of large gas plants, also conditioned by permits and infrastructure, the reuse of existing reactors is proposed as a way to gain speed. The logic is simple: start from equipment that is already manufactured and tested, and convert it into a firm supply for the network. It is, at least on paper, a way to add base power while other solutions mature. Behind the scenes of the proposal. The initiative does not come from a newly created startup or from an unknown actor in the energy sector. HGP Intelligent Energy It is a recently created division, but it is presented as part of a developer with previous experience in the US market, supported, according to the company itself, in energy storage projects, electric mobility and development of network-scale assets. At the helm is Gregory Alvaro Forero, president of the division, which appears on your LinkedIn profile as president of HGP Storage since November 2013. That detail helps frame the approach outside of the improvised company pattern. What technology would be reused and at what price. The reactors cited in the proposal come from the US naval nuclear fleet, where aircraft carriers operate with two reactors and submarines typically operate with one. Models A4W, manufactured by Westinghouse, and S8G, developed by General Electric, are mentioned. Adaptation for civil use would have an estimated cost of between one and four million dollars per megawatt, and the project would also require between 1.8 and 2.1 billion dollars in private capital for associated infrastructure. The proposal includes revenue sharing with the Government, a fund for future decommissioning and the intention to request a loan guarantee from the Department of Energy, with a first phase “as soon as 2029”. Just because the idea sounds direct doesn’t mean the path is. Bloomberg notes that Reusing military reactors for civilian use would be unexplored territory, and inevitable questions arise: how is it authorized, who operates, under what standards and with what responsibilities if something fails. Coordination between federal agencies and regulators also comes into play, as well as the logistics of moving and adapting equipment designed for ships, not a grid-connected plant. For now, everything remains at the proposal level. Energy sovereignty as a security argument. HGP tries to support its approach with a framework that goes beyond electricity for data centers. In its materials, the company summarizes the idea with an explicit equation, “Energy Supply Chain Sovereignty = National Defense,” and links supply chain resilience to the country’s ability to secure strategic infrastructure, even noting how geopolitical events or social media posts by managers can affect operations and investments. It is the story with which it seeks political and institutional legitimacy. To reinforce the idea that naval nuclear is not synonymous with improvisation, the context of the World Association of Nuclear Operators enters. According to WANOthe US Navy has accumulated more than 6,200 reactor-years of experience without radiological incidents, with 526 reactor cores, as of 2021. The association attributes that history to the standardization of systems, maintenance and quality of training. It is a relevant fact for the public debate, but it does not close it: a solid record in a military environment does not automatically imply that the jump to civilian use will be immediate or easy.

Renault is already pushing for Europe to copy the Chinese model

November 14, 2025 by usatoday24

The statements have been as concise as they are clear: “You cannot come to Europe and build four plates with wheels and seats with little added value. What we have to do is commit them to teach us, to come with products with added value. We did not do it like that when we went to China, they should not do it when they come to Europe” The words are from Josep Maria Recasens, president of Renault Spain, and reflect in three sentences the situation that the industry is experiencing in Europe, its internal debates and its fears. Added value. This is what Recasens has demanded at the 1st Automotive Forum, organized by the Automotive Press Group to which it belongs. The Automotive Tribune. The president of Renault Spain, who is also the president of ANFAC (the manufacturers’ association in our country) has demanded that Europe force Chinese brands to associate with European ones so that they “teach us” how they make their products. In Recasens’ opinion, Europe is opening the door to Chinese brands, allowing them to build “four plates with wheels and seats with little added value.” It is a veiled statement that points to the Chinese factories that are settling in our country but that, however, plan to produce vehicles based on kits that already come pre-assembled from China. What do they teach us? When the president of Renault asks that the European Union force Chinese manufacturers “to teach us” it is for two reasons. The first is that China forced foreign manufacturers to partner with their local firms to produce on its soil. What did they earn? Obviously, knowledge. Just take a look at the MG4 Electric to understand the extent to which its partnership with Volkswagen has borne fruit. At the same time, foreign manufacturers could produce at a much lower price and had access to the largest market in the world. What, we assume, they did not imagine is that China was going to surpass the West. Yes, let them teach us. The second point referred to in “let them teach us” is evident: the president of Renault and Anfac recognizes that, at least in part, China is ahead. And the French company itself has gone to Shanghai to develop your Renault Twingoa car whose heart has been created internally in China in record time for the European industry. But there have also been curious situations such as Mazda has brought the Mazda 6e to Europea car developed by Changan in China that, given its success, they have decided to test on European soil with a groundbreaking price per size. And the warnings don’t end there. The industry has entered a fever to shorten deadlines and approaching the times of Chinese development. The consultants warn that, at the level of quality, there is no difference with the Europeans. Others warn Japanese firms that their extreme attention to detail and conservative evolutions they may have left them behind. In question. Recasens’ words also emphasize the misgivings that have arisen among European manufacturers seeing how Chinese companies are arriving on our soil. With the intention of stopping the arrival of Chinese electric cars at knockdown prices, Europe applied variable tariffs to each brand depending on the supposed help they have received from the Chinese Government in the form of soft loans or the transfer of land. The promise is that they would not pay if they manufactured in Europe. But the first factories are also in question. Chery opted for assemble car kits in Barcelona. That is, cars that arrive almost assembled from the other side of the world and to which the final touches are given in the Spanish city. Now, the European Union is studying whether or not the electric Omoda 5 has to pay tariffs by understanding that added value is not being created around the production of said car. But not only Chery. The Chery case was the first but it has not been the only one. Stéphane Séjourné, vice president for Prosperity and Industrial Strategy of the European Commission, has assured the Italian newspaper La Stampa that the institution also has the factory in its sights BYD in Hungary or the plans that CATL has in Europe (including those that has in Spain with Stellantis). According to Séjourné, “it is not right” that these companies are manufacturing their cars in Europe with Chinese components and Chinese employees, noting that their investment in creating a local network of suppliers is minimal. A good example is the CATL battery production plant in Aragón where it is expected that employ 2,000 Chinese employees.
