An anonymous reader quotes a report from OilPrice.com: China installed its highest solar power capacity for a single month in May, according to official data, which showed mind-boggling figures that the country installed more solar capacity in a month than any other nation did for the entire 2024. With 93 gigawatts (GW) of solar capacity installed in May, China smashed its own record of 71 GW in December 2024, per data from the National Energy Administration cited by Bloomberg.

China's solar capacity additions in May were rushed ahead of a new government policy -- effective June 1 -- to remove pricing protection for solar power projects. Under these protections, solar projects had all but guaranteed profits when they start operations. Another new rule, effective May 1, made connecting rooftop panels to the grid more difficult. These new policies are expected to moderate the growth in solar power additions this summer, analysts say. A separate report notes that China's cumulative installed solar capacity has surpassed 1 TW, according to the National Energy Administration (NEA). "By the end of May 2025, solar capacity had reached 1.08 TW (1,080 GW), up 56.9% year on year," reports pv magazine.

"NEA data show total power generation capacity stood at 3.61 TW at the end of May, an 18.8% increase from a year earlier."

Now that schools still require kids to print stuff at home (mine are in 2nd and 4th grade), and my wife also needs to use the printer, I think it may be wise to invest in a good-quality printer that has a lower cost per page (maybe laser?).

In that context, I'd love to have unbiased information about brand quality, printing technology, cost efficiency, and other factors that I might have missed. Any thoughts?

New York will construct the first major new U.S. nuclear power plant in more than 15 years, with Governor Kathy Hochul directing the state's public electric utility to add at least one gigawatt of nuclear generation capacity. The New York Power Authority will identify an upstate location and determine reactor design, either independently or through private partnerships.

The project tests President Trump's May executive orders aimed at accelerating nuclear development through regulatory overhaul, expedited licensing, and expanded use of federal lands for reactors. Only five new commercial reactors have come online since 1991, while nuclear capacity has declined more than 4% from its 2012 peak. Potential sites include grounds of New York's three existing plants owned by Constellation Energy. The state is already collaborating with Constellation on federal grant applications for reactor additions at the Nine Mile Point facility in Oswego and studying Ontario's small modular reactor initiatives.

The classic VW bus got an all-electric update — but that was just the beginning. Now there's an autonomous driving version (that's intended for commercial fleets, reports Jalopnik, "a level 4 vehicle that drives set routes" that's "going into full production" as the ID Buzz AD. (The AD stands for "autonomous driving") The AD version sports a longer wheelbase and a higher roofline than its mere human-driven sibling, which helps it to fit in the 13 cameras, nine LiDARs, and five radars that will (hopefully) allow the car to drive without crashing into anybody. These are intended for large-fleet customers providing taxi services, either ones run by local governments or private companies. [Volkswagen Group software subsidiary MOIA] has already lined up its first customer, the German city of Hamburg, which will provide the automated Buzz as a public transit option alongside traditional bus and subway services. If all goes well, after Hamburg MOIA "will bring sustainable, autonomous mobility to large-scale deployment in Europe and the U.S.," according to VW Group CEO Oliver Blume. Down the road, VW has also signed an agreement for rideshare juggernaut Uber to use the ID Buzz AD across America, starting with Los Angeles in 2026.

The ID Buzz AD is the first vehicle in Germany to reach SAE International's threshold for Level 4 autonomous driving, meaning that the car can drive itself, with no need for a driver behind the wheel, within designated areas.
It comes with "a full suite of tools for public and private transit providers," notes the EV news site Electrek. "That includes everything from the self-driving tech to fleet management software, passenger support, and operator training. That will allow cities and companies to launch driverless fleets quickly, safely, and at scale."

And Christian Senger, a member of the board of management of VW Commercial Vehicles, tells DW the vans will be manufactured in very large numbers. The Hannover VW factory is set to produce more than 10,000 commercial vehicles. "We believe we can be the leading supplier in Europe," Senger says.... [Senger] does not expect the top dog of Germany's beleaguered auto industry to make any money, at least at first. In the long term, though, he explains that autonomous driving is the lucrative field of the future, one that promises to be much more profitable than the traditional automotive industry...

The exact price has not yet been announced but the ID. Buzz AD is unlikely to come cheap. According to Senger, buyers will have to pay a low six-figure sum (in euros) per vehicle. That means it's going to be expensive for transport companies. The Association of German Transport Companies or VDV, is calling for a nationally coordinated strategy of long-term financing, and a market launch supported by public funding, to establish the country's supremacy in this market.

U.S. consumers "rank problems with public electric vehicle charging and the time it takes to recharge as their top two reasons for rejecting electric vehicles," writes the New York Times, citing figures from data analytics firm J.D. Power.

But are things getting better? Automakers and charging companies are building new stations and updating their cars to allow drivers to more easily and quickly recharge their vehicles. They're also outfitting charging stations with items such as food and bathrooms, and making the devices more reliable. Because chargers are only as fast as the cars they connect with, automakers are designing new cars to absorb electricity at higher speeds. In addition, many automakers have cut deals with Tesla to allow owners of other cars to use the company's fast-charging network, the largest in the country and widely considered the most reliable.

Early evidence suggests efforts to improve electric vehicle charging are paying off. In recent years, J.D. Power surveys showed about 20% of attempts to charge electric vehicles at all public stations ended in failure because of faulty chargers, long lines or payment glitches. But in the first three months of 2025, overall failure rates fell to 16%, the biggest improvement since the surveys began in 2021. "The industry is finally elevating as a whole," said Brent Gruber, an executive director at J.D. Power.

The number of chargers has also increased. There were about 55,200 fast chargers in the United States in May, up from 42,200 a year earlier, according to federal data.

In February, a former Phillips 66 gas station in Apex, N.C., near Raleigh, became the first "Rechargery" from Ionna, a company created by eight automakers, including General Motors, Hyundai Motors, BMW and Mercedes-Benz. Their chargers can deliver up to 400 kilowatts of juice, much more than Tesla's 250-kilowatt Superchargers. Some cars can replenish a battery in 30 minutes or less at the higher charging speeds. When connected to chargers of 350 kilowatts or more, including those at Ionna and Electrify America, another fast-charging network, a Hyundai Ioniq 5 can fill its electric "tank" from 10% to 80% in 18 minutes...

Some models from BMW, Hyundai and Kia have also enabled a national "Plug and Charge" standard that lets car owners begin charging their vehicles at Ionna stalls without first having to use a smartphone app or swipe a credit card, eliminating a step that sometimes results in errors. Tesla's chargers have long worked this way for Tesla cars and now work with some other vehicles, including Rivian's SUVs and pickups. More cars and charging stations are expected to have plug-and-charge capability in the coming months... Nearly every major automaker is redesigning their cars with plug outlets and software that are compatible with Tesla chargers.
Infrastructure upgrades are happening elsewhere too, according to the article.Texas-based gas chain Buc-ee's is offering "premium" charging using renewable power (working with Mercedes), while Waffle House plans to install BP Pulse fast chargers next year.

J.D. Power's Gruber says that while America's federal charger program only helped construct a tiny fraction of new chargers, it did also published guidelines which helped automakers and charging companies work together and address technical problems.

As recently as 2021, GM "all but eliminated" hybrids from its future product plans, reports the New York Times. "But then a funny thing happened." Car shoppers balked at the high prices of fully electric models and the challenges of charging them. In the last few years, sales of electric vehicles have grown at a much slower rate than automakers once expected. And hybrids have stepped in to fill the gap, accounting for a large and growing share of new car sales... In the first three months of this year, hybrids — including cars that can and cannot be plugged in — made up about 14 percent of all light vehicles sold in the United States, according to the Department of Energy. That was around twice the market share of fully electric vehicles in that period...

Several automakers are slowing the introduction of new electric vehicles, and have accelerated development of new hybrids.
Robb Report looks at the current status of hybrids — and a possible future: "The charging infrastructure in most countries is not yet mature enough to support convenient mass adoption of battery-electric vehicles, and in some territories never will be," says Jonathan Hall, head of research and advanced engineering at U.K.-based consulting group Mahle Powertrain....

Porsche, active in this space since 2010, just hybridized its iconic 911 for this model year. Lamborghini also joined the trend with the debut of its 1,000 hp Revuelto hybrid in 2023. "The company doesn't plan to give up the internal-combustion engine anytime soon," says CTO Rouven Mohr. "We are also considering synthetic fuels to keep ICE vehicles running after 2030."

Hall concurs: "With the emergence of bio-based and even fully synthetic fuels, the link between the ICE and climate change can be broken." Combined with the development of better batteries, this progressive hybrid model could offer the best of both worlds for years to come.

An anonymous reader shared this report from the Washington Post: Over the past three years, companies have invested tens of billions of dollars toward making electric vehicles in the United States, buoyed by tax incentives aimed at helping American businesses compete with China. Now, those companies are facing a strange problem: too much manufacturing capacity, not enough demand.

As sales of electric vehicles slow and congressional Republicans take aim at EV tax credits and incentives, the United States is slated to have more battery and EV manufacturing than it needs, according to a report released Wednesday by the Rhodium Group, a research firm. That could leave factories — many of which are already operating or under construction — stranded if car sales continue to slump. "The rug is being pulled out from under these manufacturers," said Hannah Pitt, a director in Rhodium's energy and climate practice...

After [America's 2022 climate bill], battery investment in the U.S. skyrocketed. Companies went from investing about $1 billion per quarter in 2022 to $11 billion per quarter in 2024. Most of that battery investment went to red states, including in the South's "Battery Belt," where manufacturers were drawn to inexpensive land and a nonunionized workforce. Now, however, that battery boom is teetering. In the first three months of 2025, companies canceled $6 billion in battery manufacturing — a record. EV sales have slowed...

According to the new report, the United States has almost enough battery capacity announced or under development to meet demand all the way to 2030 if EV sales continue to slump. That might sound like a good thing — but if EV sales drop further, it means companies will be left with factories they won't be able to use. At the same time, China has excess battery capacity. The country has enough manufacturing to meet the entire world's demand for batteries — and may be looking to off-load them onto other markets... And if the incentives for using U.S.-made batteries disappear, the nation's manufacturers would be left high and dry.

An anonymous reader quotes a report from MacRumors: To comply with a new regulation that takes effect today, Apple has added an energy efficiency label to its iPhone and iPad pages in EU countries. Apple is also required to start including a printed version of the label with the devices sold there. The label grades a given iPhone or iPad model's energy efficiency from a high of A to a low of G, based on the EU's testing parameters. However, Apple said that certain aspects of the testing methods outlined by the European Commission are "ambiguous," so it chose to be conservative with its scores until testing is standardized.

In a 44-page document (PDF) detailing its testing methodology for the labels, Apple said its current iPhone models qualified for the highest energy efficiency grade of A, but the company voluntarily downgraded these scores to a B as a cautionary measure. The label also provides details about a given iPhone or iPad model's battery life per full charge cycle, repairability grade, impact resistance, ingress protection rating for water and dust resistance, and how many full charge cycles the battery is rated for. Likewise, this information is based on Apple's interpretation of the EU's testing parameters.

On the web, the label can be viewed by clicking or tapping on the colorful little tag icon on various iPhone and iPad pages on Apple's localized websites for EU countries. It is shown on both Apple's main product marketing pages for all iPhone and iPad models that are currently sold in the EU, and on the purchase page for those devices. The label is accompanied by a product information sheet (PDF) that provides a comprehensive overview of even more details, such as the device's battery capacity in mAh, screen scratch resistance based on the Mohs hardness scale, the minimum guaranteed timeframe for availability of security updates, and much more.

Turning recently closed coalmines into solar energy plants could add almost 300GW of renewable energy by 2030, converting derelict wastelands to productive use, according to a new report. From a report: In a first of its kind analysis, researchers from Global Energy Monitor (GEM) identified 312 surface coalmines closed since 2020 around the world, and 134 likely to close by the end of the decade, together covering 5,820 sq km (2,250 sq miles) -- a land area nearly the size of Palestine.

Strip mining turns terrains into wastelands, polluted and denuded of topsoil. But if they were filled with solar panels and developed into energy plants, the report claims, they could generate enough energy to power as big and power hungry a nation as Germany.

An anonymous reader quotes a report from the BBC: The Spanish government has said that the national grid operator and private power generation companies were to blame for an energy blackout that caused widespread chaos in Spain and Portugal earlier this year. Shortly after midday on April 28, both countries were disconnected from the European electricity grid for several hours. Businesses, schools, universities, government buildings and transport hubs were all left without power and traffic light outages caused gridlocks. While schoolchildren, students and workers were sent home for the day, many other people were stuck in lifts or stranded on trains in isolated rural areas.

In the immediate aftermath, the left-wing coalition government did not provide an explanation, instead calling for patience as it investigated. Nearly two months after the unprecedented outage, the minister for ecological transition, Sara Aagesen, has presented a report on its causes. She said the partly state-owned grid operator, Red Electrica, had miscalculated the power capacity needs for that day, explaining that the "system did not have enough dynamic voltage capacity." The regulator should have switched on another thermal plant, she said, but "they made their calculations and decided that it was not necessary."

Aagesen also blamed private generators for failing to regulate the grid's voltage shortly before the blackout happened. "Generation firms which were supposed to control voltage and which, in addition, were paid to do just that did not absorb all the voltage they were supposed to when tension was high," she said, without naming any of the companies responsible. The day after the outage, Prime Minister Pedro Sanchez suggested that private electricity companies might have played a role, saying that his government would demand "all the relevant accountability" from them. However, the new report on the blackout also raises questions about the role of Beatriz Corredor, president of Red Electrica and a former Socialist minister, who had previously insisted that the grid regulator had not been at fault. Aagesen said there was no evidence of a cyberattack behind the blackout. The government also maintained that Spain's renewable energy output was not to blame.

In Tokyo Mitsubishi is deploying "an innovative new battery swap network for electric cars" in a multi-year test program reports the EV news site Electrek.

But it's not just for electric cars. Along with the 14 modular battery swapping stations, Mitsubishi is also deploying "more than 150 battery-swappable commercial electric vehicles" from truck maker Fuso: A truck like the Mitsubishi eCanter typically requires a full night of AC charging to top off its batteries, and at least an hour or two on DC charging in Japan, according to Fuso. This joint pilot by Mitsubishi, Mitsubishi Fuso Trucks, and [EV battery swap specialist] Ample aims to circumvent this issue of forced downtime with its swappable batteries, supporting vehicle uptime by delivering a full charge within minutes.

The move is meant to encourage the transport industry's EV shift while creating a depository of stored energy that can be deployed to the grid in the event of a natural disaster — something Mitsubishi in Japan has been working on for years.
The article's author also adds their own opinion about battery-swapping technology. "When you see how simple it is to add hundreds of miles of driving in just 100 seconds — quicker, in many cases, than pumping a tank of liquid fuel into an ICE-powered car — you might come around, yourself."

In a world first, a research team used 2D materials — only an atom thick — to develop a computer. The team (led by researchers at Pennsylvania State University) says it's a major step toward thinner, faster and more energy-efficient electronics.

From the University's announcement: They created a complementary metal-oxide semiconductor (CMOS) computer — technology at the heart of nearly every modern electronic device — without relying on silicon. Instead, they used two different 2D materials to develop both types of transistors needed to control the electric current flow in CMOS computers: molybdenum disulfide for n-type transistors and tungsten diselenide for p-type transistors... "[A]s silicon devices shrink, their performance begins to degrade," [said lead researcher/engineering professor Saptarshi Das]. "Two-dimensional materials, by contrast, maintain their exceptional electronic properties at atomic thickness, offering a promising path forward...."

The team used metal-organic chemical vapor deposition (MOCVD) — a fabrication process that involves vaporizing ingredients, forcing a chemical reaction and depositing the products onto a substrate — to grow large sheets of molybdenum disulfide and tungsten diselenide and fabricate over 1,000 of each type of transistor. By carefully tuning the device fabrication and post-processing steps, they were able to adjust the threshold voltages of both n- and p-type transistors, enabling the construction of fully functional CMOS logic circuits.

"Our 2D CMOS computer operates at low-supply voltages with minimal power consumption and can perform simple logic operations at frequencies up to 25 kilohertz," said first author Subir Ghosh, a doctoral student pursuing a degree in engineering science and mechanics under Das's mentorship. Ghosh noted that the operating frequency is low compared to conventional silicon CMOS circuits, but their computer — known as a one instruction set computer — can still perform simple logic operations.

An anonymous reader quotes a report from the Wall Street Journal: Since 2022, the U.S. has tightened the noose around the sale of high-end AI chips and other technology to China overnational-security concerns. Yet Chinese companies have made advances using workarounds. In some cases, Chinese AI developers have been able to substitute domestic chips for the American ones. Another workaround is to smuggle AI hardware into China through third countries. But people in the industry say that has become more difficult in recent months, in part because of U.S. pressure. That is pushing Chinese companies to try a further option: bringing their data outside China so they can use American AI chips in places such as Southeast Asia and the Middle East (source paywalled; alternative source). The maneuvers are testing the limits of U.S. restrictions. "This was something we were consistently concerned about," said Thea Kendler, who was in charge of export controls at the Commerce Department in the Biden administration, referring to Chinese companies remotely accessing advanced American AI chips. Layers of intermediaries typically separate the Chinese users of American AI chips from the U.S. companies -- led by Nvidia -- that make them. That leaves it opaque whether anyone is violating U.S. rules or guidance. [...]

At the Chinese AI developer, the Malaysia game plans take months of preparation, say people involved in them. Engineers decided it would be fastest to fly physical hard drives with data into the country, since transferring huge volumes of data over the internet could take months. Before traveling, the company's engineers in China spent more than eight weeks optimizing the data sets and adjusting the AI training program, knowing it would be hard to make major tweaks once the data was out of the country. The Chinese engineers had turned to the same Malaysian data center last July, working through a Singaporean subsidiary. As Nvidia and its vendors began to conduct stricter audits on the end users of AI chips, the Chinese company was asked by the Malaysian data center late last year to work through a Malaysian entity, which the companies thought might trigger less scrutiny.

The Chinese company registered an entity in Kuala Lumpur, Malaysia's capital, listing three Malaysian citizens as directors and an offshore holding company as its parent, according to a corporate registry document. To avoid raising suspicions at Malaysian customs, the Chinese engineers packed their hard drives into four different suitcases. Last year, they traveled with the hard drives bundled into one piece of luggage. They returned to China recently with the results -- several hundred gigabytes of data, including model parameters that guide the AI system's output. The procedure, while cumbersome, avoided having to bring hardware such as chips or servers into China. That is getting more difficult because authorities in Southeast Asia are cracking down on transshipments through the region into China.

High-voltage electricity cables have become a major constraint throttling the clean energy transition, with manufacturing facilities booked out for years as demand far exceeds supply capacity. The energy transition, trade barriers, and overdue grid upgrades have turbocharged demand for these highly sophisticated cables that connect wind farms, solar installations, and cross-border power networks.

The International Energy Agency estimates that 80 million kilometers of grid infrastructure must be built between now and 2040 to meet clean energy targets -- equivalent to rebuilding the entire existing global grid that took a century to construct, but compressed into just 15 years. Each high-voltage cable requires custom engineering and months-long production in specialized 200-meter towers, with manufacturers reporting that 80-90% of major projects now use high-voltage direct current technology versus traditional alternating current systems.

Anker is recalling 1.15 million "PowerCore 10000" portable chargers due to fire and explosion risks linked to overheating lithium-ion batteries, with 19 incidents reported. "That includes two minor burn injuries and 11 reports of property damage amounting to over $60,700," reports CBS News. Consumers are urged to stop using the affected devices, check their serial numbers, and request a free replacement through Anker's website. From the report: According to a notice from the U.S. Consumer Product Safety Commission (CPSC), the lithium-ion battery inside certain "PowerCore 10000" made by Anker, a China-based electronics maker, can overheat. That can lead to the "melting of plastic components, smoke and fire hazards," Anker said in an announcement. The company added that it was conducting the recall "out of an abundance of caution to ensure the safety of our customers."

The recalled "PowerCore 10000" power banks have a model number of A1263. They were sold online at Anker's website -- as well as Amazon, eBay and Newegg -- between June 2016 and December 2022 for about $27 across the U.S., according to the recall notice. Consumers can check their serial number at Anker's site to determine whether their power bank is included in the recall.

Apple's macOS 26 "Tahoe" introduces a new disk image format called ASIF, designed to dramatically improve performance over previous formats like UDRW and sparse bundles -- achieving near-native read/write speeds for virtual machines and general disk image use. The Eclectic Light Company reports: Apple provides few technical details, other than stating that the intrinsic structure of ASIF disk images doesn't depend on the host file system's capabilities, and their size on the host depends on the size of the data stored in the disk. In other words, they're a sparse file in APFS, and are flagged as such. [...]

Conclusions:
- Where possible, in macOS 26 Tahoe in particular, VMs should use ASIF disk images rather than RAW/UDRW.
- Unless a sparse bundle is required (for example when it's hosted on a different file system such as that in a NAS), ASIF should be first choice for general purpose disk images in Tahoe.
- It would be preferable for virtualizers to be able to call a proper API rather than a command tool.
- Keep an eye on C-Command's DropDMG. I'm sure it will support ASIF disk images soon.

The United States is mounting an ambitious effort to reclaim nuclear energy leadership after falling dangerously behind China, which now has 31 reactors under construction and plans 40 more within a decade. America produces less nuclear power than it did a decade ago and abandoned uranium mining and enrichment capabilities, leaving Russia controlling roughly half the world's enriched uranium market.

This strategic vulnerability has triggered an unprecedented response: venture capitalists invested $2.5 billion in US next-generation nuclear technology since 2021, compared to near-zero in previous years, while the Trump administration issued executive orders to accelerate reactor deployment. The urgency stems from AI's city-sized power requirements and recognition that America cannot afford to lose what Interior Secretary Doug Burgum calls "the power race" with China.

Companies like Standard Nuclear in Oak Ridge, Tennessee are good examples of this push, developing advanced reactor fuel despite employees working months without pay.

Meta has struck a new deal with geothermal startup XGS Energy to supply 150 megawatts of carbon-free electricity for its New Mexico data center. "Advances in AI require continued energy to support infrastructure development," Urvi Parekh, global head of energy at Meta, said in a press release. "With next-generation geothermal technologies like XGS ready for scale, geothermal can be a major player in supporting the advancement of technologies like AI as well as domestic data center development." The Verge reports: Geothermal plants generate electricity using Earth's heat; typically drawing up hot fluids or steam from natural reservoirs to turn turbines. That tactic is limited by natural geography, however, and the US gets around half a percent of its electricity from geothermal sources. Startups including XGS are trying to change that by making geothermal energy more accessible. Last year, Meta made a separate 150MW deal with Sage Geosystems to develop new geothermal power plants. Sage is developing technologies to harness energy from hot, dry rock formations by drilling and pumping water underground, essentially creating artificial reservoirs. Google has its own partnership with another startup called Fervo developing similar technology.

XGS Energy is also seeking to exploit geothermal energy from dry rock resources. It tries to set itself apart by reusing water in a closed-loop process designed to prevent water from escaping into cracks in the rock. The water it uses to take advantage of underground heat circulates inside a steel casing. Conserving water is especially crucial in a drought-prone state like New Mexico, where Meta is expanding its Los Lunas data center. Meta declined to say how much it's spending on this deal with XGS Energy. The initiative will roll out in two phases with a goal of being operational by 2030.

The PCI-SIG, which oversees the development of the PCIe specification, has officially released the final spec for PCI Express 7.0. "The PCIe 7.0 specification increases the per-lane data transfer rate to 128 GT/s in each direction, which is twice as fast as PCIe 6.0 supports and four times faster than PCIe 5.0," reports Tom's Hardware. "Such a significant performance increase enables devices with 16 PCIe 7.0 lanes to transfer up to 256 GB/s in each direction, not accounting for protocol overhead. The new version of the interface continues to use PAM4 signaling while maintaining the 1b/1b FLIT encoding method first introduced in PCIe 6.0." From the report: To achieve PCIe 7.0's 128 GT/s record data transfer rate, developers of PCIe 7.0 had to increase the physical signaling rate to 32 GHz or beyond. Keep in mind that both PCIe 5.0 and 6.0 use a physical signaling rate of 16 GHz to enable 32 GT/s using NRZ signaling and 64 GT/s using PAM4 signaling (which allows transfers of two bits per symbol). With PCIe 7.0, developers had to boost the physical frequency for the first time since 2017, which required tremendous work at various levels, as maintaining signal integrity at 32 GHz over long distances using copper wires is extremely challenging.

Beyond raw throughput, the update also offers improved power efficiency and stronger support for longer or more complex electrical channels, particularly when using a cabling solution, to cater to the needs of next-generation data center-grade bandwidth-hungry applications, such as 800G Ethernet, Ultra Ethernet, and quantum computing, among others. [...] With the PCIe 7.0 standard officially released, members of the PCI-SIG, including AMD, Intel, and Nvidia, can begin finalizing the development of their platforms that support the PCIe specifications. PCI-SIG plans to start preliminary compliance tests in 2027, with official interoperability tests scheduled for 2028. Therefore, expect actual PCIe 7.0 devices and platforms on the market sometime in 2028 - 2029, if everything goes as planned. PCI-SIG also announced that pathfinding for PCIe 8.0 is underway, and members of the organization are actively exploring possibilities and defining capabilities of a standard that they are going to use in 2030 and beyond.

"Interestingly, when asked whether PCIe 8.0 would double data transfer rate to 256 GT/s in each direction (and therefore enable bandwidth of 1 TB/s in both directions using 16 lanes), Al Yanes, president of PCI-SIG, said that while this is an intention, he would not like to make any definitive claims," reports Tom's Hardware. "Additionally, he stated that PCI-SIG is looking forward to enabling PCIe 8.0, which will offer higher performance over copper wires in addition to optical interconnects."

An anonymous reader quotes a report from Ars Technica: Last week, electronics engineer Lorentio Brodesco announced the completion of a mock-up for nsOne, reportedly the first custom PlayStation 1 motherboard created outside of Sony in the console's 30-year history. The fully functional board accepts original PlayStation 1 chips and fits directly into the original console case, marking a milestone in reverse-engineering for the classic console released in 1994. Brodesco's motherboard isn't an emulator or FPGA-based re-creation -- it's a genuine circuit board designed to work with authentic PlayStation 1 components, including the CPU, GPU, SPU, RAM, oscillators, and voltage regulators. The board represents over a year of reverse-engineering work that began in March 2024 when Brodesco discovered incomplete documentation while repairing a PlayStation 1.

"This isn't an emulator. It's not an FPGA. It's not a modern replica," Brodesco wrote in a Reddit post about the project. "It's a real motherboard, compatible with the original PS1 chips." It's a desirable project for some PS1 enthusiasts because a custom motherboard could allow owners of broken consoles to revive their systems by transplanting original chips from damaged boards onto new, functional ones. With original PS1 motherboards becoming increasingly prone to failure after three decades, replacement boards could extend the lifespan of these classic consoles without resorting to emulation.

The nsOne project -- short for "Not Sony's One" -- uses a hybrid design based on the PU-23 series motherboards found in SCPH-900X PlayStation models but reintroduces the parallel port that Sony had removed from later revisions. Brodesco upgraded the original two-layer PCB design to a four-layer board while maintaining the same form factor. [...] As Brodesco noted on Kickstarter, his project's goal is to "create comprehensive documentation, design files, and production-ready blueprints for manufacturing fully functional motherboards." Beyond repairs, the documentation and design files Brodesco is creating would preserve the PlayStation 1's hardware architecture for future generations: "It's a tribute to the PS1, to retro hardware, and to the belief that one person really can build the impossible."
