Michelle Lewis reports via Electrek: The world's largest solar farm, in the desert in northwestern Xinjiang, is now connected to China's grid. The 3.5-gigawatt (GW), 33,000-acre solar farm is outside Urumqi, Xinjiang's capital. The state asset regulator's website cited the Power Construction Corp of China and said it came online on Monday. The solar farm will generate about 6.09 billion kilowatt hours (kWh) of electricity annually. Assuming an EV consumes about 3,000 kWh per year, 6.09 billion kWh could power 2.03 million EVs annually. The world's largest solar farm in Xinjiang is part of China's megabase project, a plan to install 455 GW of wind and solar. The megabase projects are sited in sparsely populated, resource-rich areas and send their generated energy to major urban centers, such as on China's eastern seaboard. China now boasts the three largest solar farms in the world by capacity. The Ningxia Tenggeli and Golmud Wutumeiren solar farms, each with a capacity of 3 MW, are already online.

An anonymous reader shares a report: A Chinese research team says it has uncovered a significant security flaw in processor design that could have a wide impact on China's booming domestic chip industry. China was relying on the structure of the world's largest open-source CPU architecture to build their own CPUs and bypass the US chip ban, and was paying attention to any weaknesses, they said. The issue was found in RISC-V, an open-source standard used in advanced chips and semiconductors. Compared with mainstream CPU structures -- such as X86 used by Intel and AMD --RISC-V offers free access and can be modified without restriction. The flaw allows attackers to bypass the security protections of modern processors and operating systems without administrative rights, leading to the potential theft of protected sensitive information and breaches of personal privacy. The vulnerability was confirmed by the team of Professor Hu Wei at Northwestern Polytechnical University (NPU), a major defence research institute in Shaanxi province. The researchers are experienced in hardware design security, vulnerability detection and cryptographic application safety. It was first reported by the National Computer Network Emergency Response Technical Team/Coordination Centre of China (CNCERT) on April 24, and NPU gave further details in an official announcement on May 24.

An anonymous reader shares a report: Chinese people know their country's internet is different. There is no Google, YouTube, Facebook or Twitter. They use euphemisms online to communicate the things they are not supposed to mention. When their posts and accounts are censored, they accept it with resignation. They live in a parallel online universe. They know it and even joke about it. Now they are discovering that, beneath a facade bustling with short videos, livestreaming and e-commerce, their internet -- and collective online memory -- is disappearing in chunks. A post on WeChat on May 22 that was widely shared reported that nearly all information posted on Chinese news portals, blogs, forums, social media sites between 1995 and 2005 was no longer available. "The Chinese internet is collapsing at an accelerating pace," the headline said. Predictably, the post itself was soon censored. It's impossible to determine exactly how much and what content has disappeared. [...] In addition to disappearing content, there's a broader problem: China's internet is shrinking. There were 3.9 million websites in China in 2023, down more than a third from 5.3 million in 2017, according to the country's internet regulator.

CarbonBrief: China's carbon dioxide (CO2) emissions fell by 3% in March 2024, ending a 14-month surge that began when the economy reopened after the nation's "zero-Covid" controls were lifted in December 2022. The new analysis for Carbon Brief, based on official figures and commercial data, reinforces the view that China's emissions could have peaked in 2023. The drivers of the CO2 drop in March 2024 were expanding solar and wind generation, which covered 90% of the growth in electricity demand, as well as declining construction activity. Oil demand growth also ground to a halt, indicating that the post-Covid rebound may have run its course. A 2023 peak in China's CO2 emissions is possible if the buildout of clean energy sources is kept at the record levels seen last year.

China's Chang'e-6 probe successfully lands on far side of the moon China's moon probe has "successfully touched down on the far side of the moon," CNN reports, in "a significant step for the ambitious mission that could advance the country's aspirations of putting astronauts on the moon" by 2030. The mission's ultimate goal is to return to Earth the first samples from the moon's far side, CNN reports. And China's lunar lander "is now expected to use a drill and a mechanical arm to gather up to 2 kilograms of moon dust and rocks from the basin, a crater formed some 4 billion years ago." To complete its mission, the lander will need to robotically stow those samples in an ascent vehicle that made the landing with it. The ascent vehicle will then return to lunar orbit, where it will dock with and transfer the samples to a re-entry capsule, according to mission information provided by the China National Space Administration. The re-entry capsule and orbiter will then travel back to Earth's orbit and separate, allowing the re-entry capsule to make its expected return later this month to the Siziwang Banner Landing Site in China's rural Inner Mongolia region. The mission began with its launch on May 3 — and is expected to last 53 days. The landing marks the second time a mission has successfully reached the far side of the moon. China first completed that historic feat in 2019 with its Chang'e-4 probe... The technically complex mission is made more challenging due to where it is being conducted. The far side of the moon is out of range of normal communications, which means Chang'e-6 must also rely on a satellite that was launched into lunar orbit in March, the Queqiao-2.

American Lidar, a company registered in Michigan in December, is a subsidiary of China-based lidar maker Hesai Group, which the U.S. has labeled a security concern, WSJ reported Wednesday, citing policymakers and national-security experts. Chinese firms facing regulatory or reputational problems are rebranding and creating U.S.-domiciled businesses to sell their wares as the Biden administration expands the government entity lists that restrict Chinese companies' business dealings in the U.S., the report said. These moves, while legal, irritate regulators who can't enforce laws when it isn't clear who is behind a company. Hesai became a target in the U.S.-China tech-trade war after allegations that its laser sensors could be used to collect sensitive American data, and was added to the Defense Department list that designates companies as Chinese military entities operating in the U.S. BGI Genomics and DJI are also facing similar challenges and are attempting to rebrand or license their technology to American startups to avoid sanctions.

An anonymous reader shares a report: Commercial dot-matrix printing was yet another arena in which the needs of Chinese character I/O were not accounted for. This is witnessed most clearly in the then-dominant configuration of printer heads -- specifically the 9-pin printer heads found in mass-manufactured dot-matrix printers during the 1970s. Using nine pins, these early dot-matrix printers were able to produce low-resolution Latin alphabet bitmaps with just one pass of the printer head. The choice of nine pins, in other words, was "tuned" to the needs of Latin alphabetic script. These same printer heads were incapable of printing low-resolution Chinese character bitmaps using anything less than two full passes of the printer head, one below the other. Two-pass printing dramatically increased the time needed to print Chinese as compared to English, however, and introduced graphical inaccuracies, whether due to inconsistencies in the advancement of the platen or uneven ink registration (that is, characters with differing ink densities on their upper and lower halves). Compounding these problems, Chinese characters printed in this way were twice the height of English words. This created comically distorted printouts in which English words appeared austere and economical, while Chinese characters appeared grotesquely oversized. Not only did this waste paper, but it left Chinese-language documents looking something like large-print children's books. When consumers in the Chinese-Japanese-Korean (CJK) world began to import Western-manufactured dot-matrix printers, then, they faced yet another facet of Latin alphabetic bias.

China has set up its third planned state-backed investment fund to boost its semiconductor industry, with a registered capital of 344 billion yuan ($47.5 billion), according to a filing with a government-run companies registry. Reuters: The hundreds of billions of yuan invested in the sector puts into perspective President Xi Jinping's drive to achieve self-sufficiency for China in semiconductors. That commitment has taken on renewed urgency after the U.S. imposed a series of export control measures over the last couple of years, citing fears Beijing could use advanced chips to boost its military capabilities.

China's rapid solar power expansion is slowing due to grid bottlenecks, market reforms, and diminishing rooftop space, with new solar builds dropping 32% in March year-on-year. Reuters reports: The country's solar power expansion is slowing due to tighter curbs on supplying excess power from rooftop solar into the grid and changes in electricity pricing that are denting the economics of new solar projects. Forecasts show China's solar build this year will be heavily outpaced by growth in its photovoltaic (PV) module manufacturing capacity, raising the prospect the country will export more solar panels despite a trade backlash in Europe and the U.S. The main factor slowing the expansion of distributed solar - installations built near the point of use, mostly on rooftops - is that there is not enough storage or transmission capacity to soak up the excess power generated when the sun is shining. That in turn is leading regulators to take away some of the price support that led to the rapid growth of distributed solar. "In the next couple of years, this is going to be a huge problem that all provinces will face as grids are oversaturated, the infrastructure is overwhelmed," said Cosimo Ries, an analyst with Trivium China, a policy research group. [...] Renewable generators previously enjoyed a guarantee that grid operators would buy nearly all of their power at a rate tied to the coal index. That guarantee was lifted on April 1 and took effect earlier in some places, three industry experts said. Now, renewable generation is increasingly subject to less favourable market pricing. Shenhua Energy, a state-run coal and power firm, said in its first-quarter report that prices for its solar power fell 34.2% year-on-year to 283 yuan per megawatt-hour (MWh), while its coal power prices fell just 2.4% to 406 yuan per MWh. Wang Xiuqiang, a researcher at consultancy Beijing Linghang, attributed the lower solar prices and profitability to a higher proportion of market-based pricing. At the same time, grid companies are dialling back the 5% curtailment limit, "creating the risk for project owners that their generation might not be bought", said David Fishman of Shanghai-based energy consultancy the Lantau Group. Curtailment for Huaneng Power International, a major state-owned generator, rose to 7.7% in the first quarter from 3.1% a year earlier, Jefferies analysts said in a client note, citing Huaneng management. In a further challenge, the easiest-to-site projects have already been largely developed, said Shi Lida, research manager at Yongan Guofu Asset Management. At sites still available, rooftops may need to be reinforced, grid connections may be limited, or hours of sunlight may be short. "If your costs don't continue to fall, the investment will not be cost effective," Shi said. Further reading: Germany Has Too Many Solar Panels, and It's Pushed Energy Prices Negative

Taiwan's new technology minister Wu Cheng-wen said smart machines connected to the internet, including chip tools, can be remotely shut off in the event of a conflict on the island. From a report: Wu, stepping in to oversee science and technology as part of a new administration, was responding to a lawmaker's question about a Bloomberg News report that chipmaking gear maker ASML Holding NV and Taiwan Semiconductor Manufacturing Co. have the ability to disable the world's most advanced chip machines remotely. China on Thursday escalated military exercises around the island that Beijing considers part of its territory, only days after the self-governing democracy of 23 million inaugurated a new president in Lai Ching-te. Tensions in the Taiwan Strait have caused concern in the US and other leading nations about implications for the global economy -- which counts on TSMC to produce the world's most essential chips. "According to today's smart chip manufacturing technology, it can be done," Wu said. "Whatever industry and machinery, if it is linked online, we can use this smart manufacturing technology to remotely control the machinery, including stopping it."

An anonymous reader quotes a report from Bloomberg: ASML Holding NV and Taiwan Semiconductor Manufacturing Co. have ways to disable the world's most sophisticated chipmaking machines in the event that China invades Taiwan, according to people familiar with the matter. Officials from the US government have privately expressed concerns to both their Dutch and Taiwanese counterparts about what happens if Chinese aggression escalates into an attack on the island responsible for producing the vast majority of the world's advanced semiconductors, two of the people said, speaking on condition of anonymity. ASML reassured officials about its ability to remotely disable the machines when the Dutch government met with the company on the threat, two others said. The Netherlands has run simulations on a possible invasion in order to better assess the risks, they added. The remote shut-off applies to Netherlands-based ASML's line of extreme ultraviolet machines, known within the industry as EUVs, for which TSMC is its single biggest client. EUVs harness high-frequency light waves to print the smallest microchip transistors in existence -- creating chips that have artificial-intelligence uses as well as more sensitive military applications. About the size of a city bus, an EUV requires regular servicing and updates. As part of that, the company can remotely force a shut-off which would act as a kill switch, the people said, speaking on condition of anonymity. The Veldhoven-based company is the world's only manufacturer of these machines, which sell for more than $217 million apiece.

Apple is offering discounts of up to $318 on select iPhone models in China, hoping to "defend its position in the high-end smartphone market, where it faces increasing competition from local rivals such as Huawei," reports Reuters. From the report: The increased competitive pressure on Apple comes after Huawei last month introduced its new series of high-end smartphones, the Pura 70, following the launch of the Mate 60 last August. Apple's previous discounting effort in February appears to have helped the company mitigate a sales slowdown in China. Apple's shipments in China increased by 12% in March, according to Reuters' calculations based on data from the China Academy of Information and Communications Technology (CAICT). This marks a significant improvement from the first two months of 2024, when the company experienced a 37% slump in sales.

"China's navy has apparently tested out a hypersonic rail gun," reports Futurism, describing it as "basically a device that uses a series of electromagnets to accelerate a projectile to incredible speeds." But "during a demonstration of its power, things didn't go quite as planned." As the South China Morning Post reports, the rail gun test lobbed a precision-guided projectile — or smart bomb — nine miles into the stratosphere. But because it apparently didn't go up as high as it was supposed to, the test was ultimately declared unsuccessful. This conclusion came after an analysis led by Naval Engineering University professor Lu Junyong, whose team found with the help of AI that even though the winged smart bomb exceeded Mach 5 speeds, it didn't perform as well as it could have. This occurred, as Lu's team found, because the projectile was spinning too fast during its ascent, resulting in an "undesirable tilt." But what's more interesting is the project itself. "Successful or not, news of the test is a pretty big deal given that it was just a few months ago that reports emerged about China's other proposed super-powered rail gun, which is intended to send astronauts on a Boeing 737-size ship into space.... which for the record did not make it all the way to space..." Chinese officials, meanwhile, are paying lip service to the hypersonic rail gun technology's potential to revolutionize civilian travel by creating even faster railways and consumer space launches, too. Japan and France also have railgun projects, according to a recent article from Defense One. "Yet the nation that has demonstrated the most continuing interest is China," with records of railgun work dating back as far as 2011: The Chinese team claimed that their railgun can fire a projectile 100 to 200 kilometers at Mach 6. Perhaps most importantly, it uses up to 100,000 AI-enabled sensors to identify and fix any problems before critical failure, and can slowly improve itself over time. This, they said, had enabled them to test-fire 120 rounds in a row without failure, which, if true, suggests that they solved a longstanding problem that reportedly bedeviled U.S. researchers. However, the team still has a ways to go before mounting an operational railgun on a ship; according to one Chinese article, the projectiles fired were only 25mm caliber, well below the size of even lightweight naval artillery. As with many other Chinese defense technology programs, much remains opaque about the program... While railguns tend to get the headlines, this lab has made advances in a wide range of electric and electromagnetic applications for the PLA Navy's warships. For example, the lab's research on electromagnetic launch technology has also been applied to the development of electromagnetic catapults for the PLAN's growing aircraft carrier fleet... While it remains to be seen whether the Chinese navy can develop a full-scale railgun, produce it at scale, and integrate it onto its warships, it is obvious that it has made steady advances in recent years on a technology of immense military significance that the US has abandoned.

Search giant Baidu fires its head of public relations after she outraged Gen Z workers. From a report [non-paywalled link]: The head of public relations at a major Chinese tech firm gained hundreds of thousands of followers seemingly overnight after posting a series of viral videos laying out her unapologetically tyrannical management style. The videos also earned her a pink slip from her employer after they set off an explosion of criticism among Gen Z Chinese fed up with the intense work culture that prevails in their country's tech industry. "I'm not your mother-in-law. I'm not your mom," Qu Jing, a vice president at Chinese search giant Baidu, said in one widely excoriated clip, referring to a colleague who was struggling with a recent breakup. "I only care about your results." In other videos, she criticized employees who didn't want to work weekends and dismissed complaints from one subordinate that messages she sent to a group chat late at night had kept a crying child awake. "Why should it be my business that your child was crying?" she said. On Thursday, as public outrage soared, Qu removed the videos from her account on Douyin, TikTok's sister platform in China, and replaced them with an apology. She said she had tried to do a good job but had been too impatient and hadn't adopted "a proper approach." Baidu Chief Executive Robin Li was furious at Qu and fired her on Thursday, according to people familiar with the matter. A top Baidu executive told employees that Qu's comments were "inappropriate and didn't represent and reflect the real culture and values of Baidu," the people said. The management also promised to review the company's corporate culture and working systems, they said. China's hard-charging tech industry relies heavily on a Darwinian work culture that demands near-total devotion to the workplace. Tech workers coined the term "996" to describe the typical schedule: 9 a.m. to 9 p.m., six days a week. Half a decade ago, videos like Qu's were just as likely to garner a shrug as generate controversy. But younger Chinese, much like their counterparts in the U.S., are increasingly skeptical of the pressure to work themselves ragged in pursuit of financial success. They have coined their own terms -- "lying flat" and "letting it rot" -- to describe their antipathy to the grinding ethos of 996.

An anonymous reader quotes a report from MIT Technology Review: Once a week, Sun Kai has a video call with his mother. He opens up about work, the pressures he faces as a middle-aged man, and thoughts that he doesn't even discuss with his wife. His mother will occasionally make a comment, like telling him to take care of himself -- he's her only child. But mostly, she just listens. That's because Sun's mother died five years ago. And the person he's talking to isn't actually a person, but a digital replica he made of her -- a moving image that can conduct basic conversations. They've been talking for a few years now. After she died of a sudden illness in 2019, Sun wanted to find a way to keep their connection alive. So he turned to a team at Silicon Intelligence, an AI company based in Nanjing, China, that he cofounded in 2017. He provided them with a photo of her and some audio clips from their WeChat conversations. While the company was mostly focused on audio generation, the staff spent four months researching synthetic tools and generated an avatar with the data Sun provided. Then he was able to see and talk to a digital version of his mom via an app on his phone. "My mom didn't seem very natural, but I still heard the words that she often said: 'Have you eaten yet?'" Sun recalls of the first interaction. Because generative AI was a nascent technology at the time, the replica of his mom can say only a few pre-written lines. But Sun says that's what she was like anyway. "She would always repeat those questions over and over again, and it made me very emotional when I heard it," he says. There are plenty of people like Sun who want to use AI to preserve, animate, and interact with lost loved ones as they mourn and try to heal. The market is particularly strong in China, where at least half a dozen companies are now offering such technologies and thousands of people have already paid for them. In fact, the avatars are the newest manifestation of a cultural tradition: Chinese people have always taken solace from confiding in the dead. The technology isn't perfect -- avatars can still be stiff and robotic -- but it's maturing, and more tools are becoming available through more companies. In turn, the price of "resurrecting" someone -- also called creating "digital immortality" in the Chinese industry -- has dropped significantly. Now this technology is becoming accessible to the general public. Some people question whether interacting with AI replicas of the dead is actually a healthy way to process grief, and it's not entirely clear what the legal and ethical implications of this technology may be. For now, the idea still makes a lot of people uncomfortable. But as Silicon Intelligence's other cofounder, CEO Sima Huapeng, says, "Even if only 1% of Chinese people can accept [AI cloning of the dead], that's still a huge market."

An anonymous reader quotes a report from MSN: The US has revoked licenses allowing Huawei to buy semiconductors from Qualcomm and Intel, according to people familiar with the matter, further tightening export restrictions against the Chinese telecom equipment maker. Withdrawal of the licenses affects US sales of chips for use in Huawei phones and laptops, according to the people, who discussed the move on condition of anonymity. House Foreign Affairs Committee Chairman Michael McCaul confirmed the administration's decision in an interview Tuesday. He said the move is key to preventing China from developing advanced AI. "It's blocking any chips sold to Huawei," said McCaul, a Texas Republican who was briefed about the license decisions for Intel and Qualcomm. "Those are two companies we've always worried about being a little too close to China." While the decision may not affect a significant volume of chips, it underscores the US government's determination to curtail China's access to a broad swathe of semiconductor technology. Officials are also considering sanctions against six Chinese firms that they suspect could supply chips to Huawei, which has been on a US trade restrictions list since 2019. [...] Qualcomm recently said that its business with Huawei is already limited and will soon shrink to nothing. It has been allowed to supply the Chinese company with chips that provide older 4G network connections. It's prohibited from selling ones that allow more advanced 5G access.

China launched an uncrewed lunar mission Friday that aims to bring back samples from the far side of the moon for the first time, in a potentially major step forward for the country's ambitious space program. From a report: The Chang'e-6 probe -- China's most complex robotic lunar mission to date -- blasted off on a Long March-5 rocket from the Wenchang Space Launch Center in south China's Hainan island, where space fans had gathered to watch the historic moment. The country's National Space Administration said the launch was a success. The launch marks the start of a mission that aims to be a key milestone in China's push to become a dominant space power with plans to land astronauts on the moon by 2030 and build a research base on its south pole. It comes as a growing number of countries, including the United States, eye the strategic and scientific benefits of expanded lunar exploration in an increasingly competitive field. China's planned 53-day mission would see the Chang'e-6 lander touch down in a gaping crater on the moon's far side, which never faces Earth. China became the first and only country to land on the moon's far side during its 2019 Chang'e-4 mission. Any far-side samples retrieved by the Chang'e-6 lander could help scientists peer back into the evolution of the moon and the solar system itself -- and provide important data to advance China's lunar ambitions.

Huawei, the Chinese telecommunications giant blacklisted by the US, is secretly funding cutting-edge research at American universities including Harvard through an independent Washington-based foundation. From a report: Huawei is the sole funder of a research competition that has awarded millions of dollars since its inception in 2022 and attracted hundreds of proposals from scientists around the world, including those at top US universities that have banned their researchers from working with the company, according to documents and people familiar with the matter. The competition is administered by the Optica Foundation, an arm of the nonprofit professional society Optica, whose members' research on light underpins technologies such as communications, biomedical diagnostics and lasers. The foundation "shall not be required to designate Huawei as the funding source or program sponsor" of the competition and "the existence and content of this Agreement and the relationship between the Parties shall also be considered Confidential Information," says a nonpublic document reviewed by Bloomberg. The findings reveal one strategy Shenzhen, China-based Huawei is using to remain at the forefront of funding international research despite a web of US restrictions imposed over the past several years in response to concerns that its technology could be used by Beijing as a spy tool.

An anonymous reader shared a report this week from Reuters: The U.S. Department of Commerce is reviewing the national security implications of China's work in open-source RISC-V chip technology, according to a letter sent to U.S. lawmakers... The technology is being used by major Chinese tech firms such as Alibaba Group Holding and has become a new front in the strategic competition over advanced chip technology between the U.S. and China. In November, 18 U.S. lawmakers from both houses of Congress pressed the Biden administration for its plans to prevent China "from achieving dominance in ... RISC-V technology and leveraging that dominance at the expense of U.S. national and economic security." In a letter last week to the lawmakers that was seen by Reuters on Tuesday, the Commerce Department said it is "working to review potential risks and assess whether there are appropriate actions under Commerce authorities that could effectively address any potential concerns." But the Commerce Department also noted that it would need to tread carefully to avoid harming U.S. companies that are part of international groups working on RISC-V technology.
