'Germans Have Seen the Future, and It's a Heat Pump' (nytimes.com) 203

Facing higher prices for natural gas, Germans are now embracing climate-friendly heat pumps, reports the New York Times. "So much so that heat pumps are often sold out, and the wait for a qualified installer can last months." The German government is among the fans. "This is the technology of the future," Robert Habeck, the minister for the economy, told reporters last month while announcing a government plan to promote heat pumps. "To achieve our goals, we want to get to six million customers by 2030," Mr. Habeck said....

The cost for the electricity needed to power a heat pump is about 35 percent cheaper than natural gas, according to Verivox, a company that compares energy prices for German consumers. The savings are even greater for those who can run their heat pumps off solar panels.... Sales of heat pumps in Germany have more than doubled in the past two years, especially as the price of gas has soared.... To encourage people to make the change, the government is offering subsidies that can cover up to a quarter of the upfront price of a unit, along with subsidies for other energy-efficiency improvements up to a total of €60,000.

Germany lags far behind its European neighbors, where imported natural gas was not as affordable or abundant. Residents of Finland and Norway, which rely more on electricity, have 10 times the number of heat pumps as do Germans, according to Agora Energiewende, a policy institute in Berlin. Even the Netherlands, which sits on its own wealth of natural gas but made a push for the more climate-friendly machines several years ago, has double the number of the units that Germany has.

Becoming America's #2 Seller of Electric Vehicles, Ford Passes Kia in November (cnbc.com) 73

CNBC reports: Ford Motor said Friday that it has achieved CEO Jim Farley's goal of becoming the second best-selling automaker of electric vehicles in the U.S. The Detroit automaker, citing third-party industry data, narrowly topped Hyundai/Kia to hit the goal....

Ford said its share of the electric vehicle segment was 7.4% through November, up from 5.7% a year earlier. Ford reported sales of 53,752 all-electric vehicles in the U.S. through November. Tesla, which does not break out domestic results, reported global deliveries of more than 908,000 EVs through the third quarter.

Hyundai's sales do not include the Nexo hydrogen fuel cell vehicle. The company says with that vehicle, it slightly outsold Ford in battery- and fuel cell-powered vehicles of 54,043 units through November. The sales come after the South Korean automaker lost incentives that gave buyers of its EVs tax credits of up to $7,500 under the Biden administration's Inflation Reduction Act, which took effect in August. Vehicles such as Ford's EVs that are produced in North America still qualify for the credit.

The article notes that General Motors — America's second-largest automaker — also "plans to significantly step up EV production in the coming years."

Although so far, through the third quarter of this year, "it reported sales of less than 23,000 EVs."

Huawei Teases a Smartwatch With Built-In Wireless Earbuds (theverge.com) 4

Huawei has confirmed the existence of a smartwatch it's working on featuring a pair of built-in wireless earbuds. "Huawei's account on Chinese Twitter-like site Weibo announced the existence of the device on Wednesday and promised all would be revealed on December 2," reports The Register. "But Huawei has since postponed its Winter 2022 consumer kit launch for unexplained reasons." You can view a teaser video on YouTube. The Verge adds: As the name suggests, the Huawei Watch Buds are a pair of earbuds concealed within a smartwatch that looks similar to the Huawei Watch 3. Details are a little sparse so there's no word yet on what kind of performance or battery life you can expect from either of the products, but the watch itself does appear to be running HarmonyOS.

The earbuds don't seem to resemble any previous Huawei products, sporting a bare-bones black and silver design. While the concept feels more than a little gimmicky, it could be a neat solution for runners and other sporty folks who don't want to carry a separate earbud case during a workout. (If they don't mind the extra bulk on their wrists.) [...] Addressing the elephant in the room, it's unlikely that you'll be able to buy this wacky gadget in the US anyway, regardless of its legitimacy. Huawei products have been effectively banned in the country since the company was placed on the Commerce Department's Bureau of Industry and Security Entity list in 2019.

PCI Standards Group Deflects, Assigns Blame for Melting GPU Power Connectors (arstechnica.com) 130

An anonymous reader shares a report: Nvidia's new RTX 4090 and 4080 GPUs both use a new connector called 12VHPWR to deliver power as a way to satisfy ever-more power-hungry graphics cards without needing to set aside the physical space required for three or four 8-pin power connectors. But that power connector and its specifications weren't created by Nvidia alone -- to ensure interoperability, the spec was developed jointly by the PCI Express Special Interest Group (PCI-SIG), a body that includes Nvidia, AMD, Intel, Arm, IBM, Qualcomm, and others.

But the overheating and melting issues experienced by some RTX 4090 owners recently have apparently prompted the PCI-SIG to clarify exactly which parts of the spec it is and is not responsible for. In a statement reported by Tom's Hardware, the group sent its members a reminder that they, not the PCI-SIG, were responsible for safety testing products using connector specs like 12VHPWR. "Members are reminded that PCI-SIG specifications provide necessary technical information for interoperability and do not attempt to address proper design, manufacturing methods, materials, safety testing, safety tolerances, or workmanship," the statement reads. "When implementing a PCI-SIG specification, Members are responsible for the design, manufacturing, and testing, including safety testing, of their products."

Government Scientists 'Approaching What is Required for Fusion' in Breakthrough Energy Research (vice.com) 135

Scientists hoping to harness nuclear fusion -- the same energy source that powers the Sun and other stars -- have confirmed that magnetic fields can enhance the energy output of their experiments, reports a new study. The results suggest that magnets may play a key role in the development of this futuristic form of power, which could theoretically provide a virtually limitless supply of clean energy. Motherboard reports: Fusion power is generated by the immense energy released as atoms in extreme environments merge together to create new configurations. The Sun, and all the stars in the night sky, are fueled by this explosive process, which occurs in their cores at incredibly high temperatures and pressures. Scientists have spent roughly a century unraveling the mechanics of nuclear fusion in nature, and trying to artificially replicate this starry mojo in laboratories. Now, a team at the National Ignition Facility (NIF), which is a fusion experiment based at the U.S. Department of Energy's Lawrence Livermore National Laboratory, has reported that the magnetic fields can boost the temperature of the fusion "hot spot" in experiments by 40 percent and more than triple its energy output, which is "approaching what is required for fusion ignition" according to a study published this month in Physical Review Letters.

"The magnetic field comes in and acts kind of like an insulator," said John Moody, a senior scientist at the NIF who led the study, in a call with Motherboard. "You have what we call the hot spot. It's millions of degrees, and around it is just room temperature. All that heat wants to flow out because heat always goes from the hot to the cold and the magnetic field prevents that from happening." "When we go in and we put the magnetic field on this hotspot, and we insulate it, now that heat stays in there, and so we're able to get the hot spot to a higher temperature," he continued. "You get more [fusion] reactions as you go up in temperature, and that's why we see this improvement in the reactivity."

The hot spots in the NIF's fusion experiments are created by shooting nearly 200 lasers at a tiny pellet of fuel made of heavier isotopes (or versions) of hydrogen, such as deuterium and tritium. These laser blasts generate X-rays that make the small capsule implode, producing the kinds of extreme pressures and temperatures that are necessary for the isotopes to fuse together and release their enormous stores of energy. NIF has already brought their experiments to the brink of ignition, which is the point at which fusion reactions become self-sustaining in plasmas. The energy yields created by these experiments are completely outweighed by the energy that it takes to make these self-sustaining reactions in the plasmas in the first place. Still, achieving ignition is an important step toward creating a possible "breakeven" system that produces more energy output than input. Moody and his colleagues developed their magnetized experiment at NIF by wrapping a coil around a version of the pellet made with specialized metals.

San Francisco Supervisors Vote To Allow Police To Use Robots To Kill (cnn.com) 129

The San Francisco Board of Supervisors voted 8-3 Tuesday night to approve a controversial policy that would allow police to deploy robots capable of using lethal force in extraordinary circumstances, according to multiple reports. From a report: The Washington Post reports the vote came after a heated debate on a policy that would allow officers to use ground-based robots to kill "when risk of loss of life to members of the public or officers is imminent and officers cannot subdue the threat after using alternative force options or de-escalation tactics." The Post says the measure still requires a second vote next week and the mayor's approval.

"There could be an extraordinary circumstance where, in a virtually unimaginable emergency, they might want to deploy lethal force to render, in some horrific situation, somebody from being able to cause further harm," Supervisor Aaron Peskin said at the board meeting, according to the San Francisco Chronicle. But Supervisors Dean Preston, Hillary Ronen and Shamann Walton voted against the policy, the Chronicle reported. "There is serious potential for misuse and abuse of this military-grade technology, and zero showing of necessity," Preston said at the meeting. Ultimately, the board adopted an amendment requiring one of two high-ranking San Francisco Police Department leaders to authorize any use of a robot for lethal force, according to the Chronicle.

Dropbox Acquires Boxcryptor Assets To Bring Zero-Knowledge Encryption To File Storage (techcrunch.com) 12

An anonymous reader quotes a report from TechCrunch: Dropbox has announced plans to bring end-to-end encryption to its business users, and it's doing so through acquiring "key assets" from Germany-based cloud security company Boxcryptor. Terms of the deal were not disclosed. Dropbox is well-known for its cloud-based file back-up and sharing services, and while it does offer encryption for files moving between its servers and the destination, Dropbox itself has access to the keys and can technically view any content passing through. What Boxcryptor brings to the table is an extra layer of security via so-called "zero knowledge" encryption on the client side, giving the user full control over who is allowed to decrypt their data.

For many people, such as consumers storing family photos or music files, this level of privacy might not be a major priority. But for SMEs and enterprises, end-to-end encryption is a big deal as it ensures that no intermediary can access their confidential documents stored in the cloud -- it's encrypted before it even arrives. Moving forward, Dropbox said that it plans to bake Boxcryptor's features natively into Dropbox for business users.
"In a blog post published today, Boxcryptor founders Andrea Pfundmeier and Robert Freudenreich say that their 'new mission' will be to embed Boxcryptor's technology into Dropbox," adds TechCrunch. "And after today, nobody will be able to create an account or buy any licenses from Boxcryptor -- it's effectively closing to new customers."

"But there are reasons why the news is being packaged the way it has. The company is continuing to support existing customers through the duration of their current contracts."

Rolls-Royce Successfully Tests Hydrogen-Powered Jet Engine (reuters.com) 133

Britain's Rolls-Royce said it has successfully run an aircraft engine on hydrogen, a world aviation first that marks a major step towards proving the gas could be key to decarbonizing air travel. Reuters reports: The ground test, using a converted Rolls-Royce AE 2100-A regional aircraft engine, used green hydrogen created by wind and tidal power, the British company said on Monday. Rolls and its testing program partner easyJet are seeking to prove that hydrogen can safely and efficiently deliver power for civil aero engines. They said they were already planning a second set of tests, with a longer-term ambition to carry out flight tests. Hydrogen is one of a number of competing technologies that could help the aviation industry achieve its goal of becoming net zero by 2050.

Epson To End the Sale and Distribution of Laser Printer (theregister.com) 191

Japanese electronics and printer maker Epson announced this month that it will end the sale and distribution of laser printer hardware by 2026, citing sustainability issues. From a report: According to the company, inkjets have a "greater potential" than laser printers to make "meaningful advances" when it comes to the environment. The company already halted laser printer sales in many markets, but continued in Asia and Europe. Even though new hardware would be unavailable everywhere, Epson said it would continue to support consumers with consumables and spare parts.

"As a company we're totally committed to sustainable innovation and action, and inkjets simply use less energy and fewer consumable parts," explained Epson sales and marketing manager Koichi Kubota in canned statement. "While laser printers work by heating and fusing toner to a page, Epson's Heat-Free inkjet technology consumes less electricity by using mechanical energy to fire ink onto the page."

A Light-powered Catalyst Could Be Key For Hydrogen Economy (phys.org) 80

"Rice University researchers have engineered a key light-activated nanomaterial for the hydrogen economy," the University announced this week.

"Using only inexpensive raw materials, a team from Rice's Laboratory for Nanophotonics, Syzygy Plasmonics Inc. and Princeton University's Andlinger Center for Energy and the Environment created a scalable catalyst that needs only the power of light to convert ammonia into clean-burning hydrogen fuel...." The research follows government and industry investment to create infrastructure and markets for carbon-free liquid ammonia fuel that will not contribute to greenhouse warming. Liquid ammonia is easy to transport and packs a lot of energy, with one nitrogen and three hydrogen atoms per molecule. The new catalyst breaks those molecules into hydrogen gas, a clean-burning fuel, and nitrogen gas, the largest component of Earth's atmosphere. And unlike traditional catalysts, it doesn't require heat. Instead, it harvests energy from light, either sunlight or energy-stingy LEDs....

"This discovery paves the way for sustainable, low-cost hydrogen that could be produced locally rather than in massive centralized plants," said Peter Nordlander, also a Rice co-author.

Europe's Biggest Battery Storage System Switched On (bbc.com) 160

What is thought to be Europe's biggest battery energy storage system has begun operating near Hull. The BBC reports: The site, said to be able to store enough electricity to power 300,000 homes for two hours, went online at Pillswood, Cottingham, on Monday. Its launch was brought forward four months as the UK faces possible energy shortages this winter. The facility was developed by North Yorkshire renewable power firm Harmony Energy using technology made by Tesla.

The Pillswood facility has the capacity to store up to 196 MWh energy in a single cycle. It has been built next to the National Grid's Creyke Beck substation, which will be connected to Dogger Bank, the world's largest offshore wind farm, when it launches in the North Sea later this decade. The system, which will use Tesla's AI software to match energy supply to demand, had been due to be switched on in two stages in December 2022 and March 2023.
Peter Kavanagh, director of Harmony Energy, said: "Battery energy storage systems are essential to unlocking the full potential of renewable energy in the UK and we hope this particular one highlights Yorkshire as a leader in green energy solutions."

"These projects are not supported by taxpayer subsidy and will play a major role in contributing to the Net Zero transition, as well as ensuring the future security of the UK's energy supply and reduced reliance on foreign gas imports."

Frederick P. Brooks Jr., Computer Design Innovator, Dies at 91 16

Frederick P. Brooks Jr., whose innovative work in computer design and software engineering helped shape the field of computer science, died on Thursday at his home in Chapel Hill, N.C. He was 91. His death was confirmed by his son, Roger, who said Dr. Brooks had been in declining health since having a stroke two years ago. The New York Times reports: Dr. Brooks had a wide-ranging career that included creating the computer science department at the University of North Carolina and leading influential research in computer graphics and virtual reality. But he is best known for being one of the technical leaders of IBM's 360 computer project in the 1960s. At a time when smaller rivals like Burroughs, Univac and NCR were making inroads, it was a hugely ambitious undertaking. Fortune magazine, in an article with the headline "IBM's $5,000,000,000 Gamble," described it as a "bet the company" venture.

Until the 360, each model of computer had its own bespoke hardware design. That required engineers to overhaul their software programs to run on every new machine that was introduced. But IBM promised to eliminate that costly, repetitive labor with an approach championed by Dr. Brooks, a young engineering star at the company, and a few colleagues. In April 1964, IBM announced the 360 as a family of six compatible computers. Programs written for one 360 model could run on the others, without the need to rewrite software, as customers moved from smaller to larger computers. The shared design across several machines was described in a paper, written by Dr. Brooks and his colleagues Gene Amdahl and Gerrit Blaauw, titled "Architecture of the IBM System/360." "That was a breakthrough in computer architecture that Fred Brooks led," Richard Sites, a computer designer who studied under Dr. Brooks, said in an interview.

But there was a problem. The software needed to deliver on the IBM promise of compatibility across machines and the capability to run multiple programs at once was not ready, as it proved to be a far more daunting challenge than anticipated. Operating system software is often described as the command and control system of a computer. The OS/360 was a forerunner of Microsoft's Windows, Apple's iOS and Google's Android. At the time IBM made the 360 announcement, Dr. Brooks was just 33 and headed for academia. He had agreed to return to North Carolina, where he grew up, and start a computer science department at Chapel Hill. But Thomas Watson Jr., the president of IBM, asked him to stay on for another year to tackle the company's software troubles. Dr. Brooks agreed, and eventually the OS/360 problems were sorted out. The 360 project turned out to be an enormous success, cementing the company's dominance of the computer market into the 1980s.
"Fred Brooks was a brilliant scientist who changed computing," Arvind Krishna, IBM's chief executive and himself a computer scientist, said in a statement. "We are indebted to him for his pioneering contributions to the industry."

Dr. Brooks published a book in 1975 titled, "The Mythical Man-Month: Essays on Software Engineering." It was "a quirky classic, selling briskly year after year and routinely cited as gospel by computer scientists," reports the Times.

San Francisco Police Seek Permission For Its Robots To Use Deadly Force (engadget.com) 143

An anonymous reader quotes a report from Engadget: The San Francisco Police Department is currently petitioning the city's Board of Supervisors for permission to deploy robots to kill suspects that law enforcement deems a sufficient threat that the "risk of loss of life to members of the public or officers is imminent and outweighs any other force option available to SFPD." The draft policy, which was written by the SFPD itself, also seeks to exclude "hundreds of assault rifles from its inventory of military-style weapons and for not include personnel costs in the price of its weapons," according to a report from Mission Local.

As Mission Local notes, this proposal has already seen significant opposition from both within and without the Board. Supervisor Aaron Peskin, initially pushed back against the use of force requirements, inserting "Robots shall not be used as a Use of Force against any person," into the policy language. The SFPD removed that wording in a subsequent draft, which I as a lifelong San Francisco resident did not know was something that they could just do. The three-member Rules Committee, which Peskin chairs, then unanimously approved that draft and advanced it to the full Board of Supervisors for a vote on November 29th. Peskin excused his decision by claiming that "there could be scenarios where deployment of lethal force was the only option."

The police force currently maintains a dozen fully-functional remote-controlled robots, which are typically used for area inspections and bomb disposal. However, as the Dallas PD showed in 2016, they make excellent bomb delivery platforms as well. Bomb disposal units are often equipped with blank shotgun shells used to forcibly disrupt an explosive device's internal workings, though there is nothing stopping police from using live rounds if they needed, as Oakland police recently acknowledged to that city's civilian oversight board.

GPU Market Nosedives, Sales Lowest In a Decade (tomshardware.com) 73

Shipments of integrated and discrete graphics processing units dropped to a 10-year low in the third quarter as PC OEMs reduced procurements of CPUs, and gamers lowered their purchases of existing graphics cards while waiting for next-generation products. From a report: In contrast, miners ceased to buy graphics boards due to changes that happened to Ethereum. In general, sales of standalone graphics cards for desktops hit a multi-year low. Usually, PC makers increase procurement of PC hardware components in the third quarter as they assemble computers to sell them in back-to-school and holiday seasons when sales are high. But as demand for PCs softened recently, manufacturers initiated inventory corrections and lowered their components buying to sell off what they already have. As a result, sales of integrated and discrete GPU dropped to 75.5 million units in Q3 2022, down 10.5% sequentially and 25.1% year-over-year, according to Jon Peddie Research. In addition, shipments of desktop GPUs fell by 15.43%, and notebook GPUs decreased by 30%, which is the most significant drop since the 2009 recession, JPR notes.

Android TV Will Require App Bundles In 2023, Should Reduce App Size By 20% (arstechnica.com) 14

An anonymous reader quotes a report from Ars Technica: Google announced that Android's space-saving app file format, Android App Bundles (AABs), will finally be the standard on Android TV. By May 2023 -- that's in six months -- Google will require all Android TV apps to switch to the new file format, which can cut down on app storage requirements by 20 percent.

Android App Bundles were announced with Android 9 in 2018 as a way to save device storage by breaking an app up into modules, rather than one big monolithic APK (the old Android app format) with every possible piece of data. Android apps support a ton of different languages, display resolutions, and CPU architectures, but each individual device only needs to cherry-pick a few of those options to work. Android App Bundles integrate with the Play Store to create a dynamic delivery system for each module. Your phone communicates which modules it needs to the Play Store, and Google's servers bundled up an appropriate package and sent it to your device. It's even possible for developers to move some lesser-used app functionality into a bundle that can be downloaded on the fly if a user needs it. [...]

Google says Android App Bundles average around a 20 percent space savings compared to a monolithic APK, which will be a huge help for these storage-starved devices. Since 2021, they have been the required standard for phones and tablets, and in six months, TV apps will be required to use them, too. Developers who don't switch in time will have their TV apps hidden from search, so they'd better get to work! Google estimates that "in most cases it will take one engineer about three days to migrate."

US Grants $1.1 Billion To Keep Diablo Canyon Nuclear Plant Open (reuters.com) 133

The Biden administration said on Monday it has approved conditional funding of up to $1.1 billion to prevent the closure of the Diablo Canyon nuclear power plant in California, as part of its effort to fight climate change. Reuters reports: The Pacific Gas & Electric plant, which was set to fully shut in 2025, applied for funding in the initial phase of the Department of Energy's (DOE) $6 billion Civil Nuclear Credit program meant to help keep struggling nuclear power reactors open. Diablo is the last operating nuclear plant in California. The Biden administration believes nuclear power is critical in curbing climate change and wants to keep plants open ahead of the development of next-generation reactors. President Joe Biden wants to decarbonize the power grid by 2035.

The U.S. nuclear power industry's 92 reactors generate more than half of the country's virtually carbon-free electricity. But about a dozen reactors have closed since 2013 in the face of competition from renewable energy and plants that burn plentiful natural gas. U.S. Secretary of Energy Jennifer Granholm said the grant was a "critical step toward ensuring that our domestic nuclear fleet will continue providing reliable and affordable power to Americans as the nation's largest source of clean electricity."

TSMC To Bring Its Most Advanced Chip Manufacturing To Arizona (cnn.com) 63

Taiwan Semiconductor Manufacturing Company plans to bring its most advanced technology to Arizona, the founder of the chip giant said Monday. From a report: TSMC's plans come as tensions between Washington and Beijing are rising over chips, with President Joe Biden imposing a sweeping set of controls on the sale of advanced chips and chip-making equipment to Chinese firms. Taiwan, a self-governing democracy that the Chinese Communist Party claims as its own territory despite having never controlled it, has also faced growing military aggression from Beijing in recent months -- throwing a spotlight on the critical role the island plays in the global chipmaking industry. TSMC accounts for an estimated 90% of the world's super-advanced computer chips, supplying tech giants including Apple and Qualcomm.

"Chips are very important products," TSMC's founder Morris Chang said Monday at a press briefing in Taipei. "It seems that people are only starting to realize this recently, and as a result, lots of people out there are envious of Taiwan's chip manufacturing." Chang has retired but remains an influential force within the industry. [...] Advances in chip manufacturing require etching ever-smaller transistors on to silicon wafers. Chang said its plant in Arizona will produce 3-nanometer chips, TSMC's most advanced technology. In 2020, the company had already committed at least $12 billion to build its first facility in Arizona. At the time, the tech giant had said that the facility will "utilize TSMC's 5-nanometer technology for semiconductor wafer fabrication" and "create over 1,600 high-tech professional jobs directly." Production is expected to begin in 2024.

Debate at COP27: Nuclear Energy, Climate Friend or Foe? (youtube.com) 273

Long-time Slashdot reader gordm shares an interesting video from the United Nations Climate Change Conference. "At COP27, Tobias Holle (activist with Youth Strike for Climate) debated Mark Nelson (founder of Radiant Energy Fund) as to whether nuclear power can help us tackle climate change."

The event took place at the International Atomic Energy Agency's "Atoms for Climate" pavillion, where the IAEA's climate advisor presented the debate's topic as "Nuclear Energy: Climate Friend or Foe?" (and introduced the two debaters as "enthusiastic young climate champions"). The Youth Strike for Climate activist objected to commiting humanity to 1 million years of maintaining nuclear waste. But he also argued that extreme weather was creating additional security risks, that the per-kilowatt hour cost was economically prohibitive, that nuclear plants were politically unpopular — and that anyways, they take too long to build given our current climate crisis. "We need fast solutions."

The Radiant Energy founder disagreed, arguing over specific statistics and insisting that nuclear energy should be considered a low-carbon energy solution, and also safe. (He pointed out that Chernobyl's nuclear plant actually continued operating for 14 years after its 1986 nuclear accident.) Interestingly he also argued that in the Netherlands there's a museum of nuclear waste — a science museum attached to their nuclear facility — "where they don't just have the high-level waste, they have the highest part of high-level waste, the most dangerous isotopes, separated from the nuclear fuel. The most radioactive stuff — very hot for 500 years — and they have a tour where you can walk over it, and you can feel the warmth from the floor from the radioactive isotopes....

"You can absolutely manage the safe, secure, and even educational storage of the most radioactive isotopes... We know very well how to manage it."

Nvidia on Melting RTX 4090 Cables: You're Plugging It In Wrong (theverge.com) 127

NVIDIA has responded to a class action lawsuit over melting RTX 4090 GPU adapters. The Verge reports: Weeks after Nvidia announced that it was investigating reports that the power cables for its RTX 4090 graphics card were melting and burning, the company says it may know why: they just weren't plugged in all the way.

In a post to its customer support forum on Friday, Nvidia says that it's still investigating the reports, but that its findings "suggest" an insecure connector has been a common issue. It also says that it's gotten around 50 reports of the issue.

Nvidia's flagship card uses what's known as a 12VHPWR power connector, a new standard that isn't natively supported by most of the power supplies that people already have in their PCs. Because of that, it ships an adapter — or "power dongle," as Friday's post calls it — in the box. Users' initial reports blamed the adapter, with some saying that the melting cable had damaged their $1,599 GPU as well....

GamersNexus, an outlet that's respected in the PC-building community for its rigorous testing, basically came to the same conclusion earlier this week. A video posted on Wednesday by the outlet, which inspected damaged adapters sent in by viewers and done extensive testing and reporting on the issue, showed that the connectors had wear lines, implying that they hadn't been completely inserted into the slot. GamersNexus even says that some people seem to have missed a full connection by several millimeters. Its video shows that a loose connection could cause the plug to heat up dramatically, if it were plugged in poorly and tilted at an angle..... [A]n unnamed spokesperson for the company told GamersNexus on Friday that "any issues with the burned cable or GPU, regardless of cable or GPU, it will be processed" for a replacement.
