An anonymous reader quotes a report from Ars Technica: Two researchers at the University of California, Davis -- Yanning Li and Alan Jenn -- have determined that nearly two-thirds of [California's] feeder lines don't have the capacity that will likely be needed for car charging. Updating to handle the rising demand might set its utilities back as much as 40 percent of the existing grid's capital cost. Li and Jenn aren't the first to look at how well existing grids can handle growing electric vehicle sales; other research has found various ways that different grids fall short. However, they have access to uniquely detailed data relevant to California's ability to distribute electricity (they do not concern themselves with generation). They have information on every substation, feeder line, and transformer that delivers electrons to customers of the state's three largest utilities, which collectively cover nearly 90 percent of the state's population. In total, they know the capacity that can be delivered through over 1,600 substations and 5,000 feeders.[...]

By 2025, only about 7 percent of the feeders will experience periods of overload. By 2030, that figure will grow to 27 percent, and by 2035 -- only about a decade away -- about half of the feeders will be overloaded. Problems grow a bit more slowly after that, with two-thirds of the feeders overloaded by 2045, a decade after all cars sold in California will be EVs. At that point, total electrical demand will be close to twice the existing capacity. The problems aren't evenly distributed, though. They appear first in high-population areas like the Bay Area. And throughout this period, most of the problems are in feeders that serve residential and mixed-use neighborhoods. The feeders that serve neighborhoods that are primarily business-focused don't see the same coordinated surge in demand that occurs as people get home from work and plug in; they're better able to serve the more erratic use of charging stations at office complexes and shopping centers. In terms of the grid, residential services will need to see their capacity expand by about 16 gigawatts by 2045. Public chargers will need nine gigawatts worth of added capacity by the same point. The one wild card is direct current fast charging. Eliminating fast chargers entirely would reduce the number of feeders that need upgrades by 12 percent. Converting all public stations to DC fast charging, in contrast, would boost that number by 15 percent. So the details of the upgrades that will be needed will be very sensitive to the impatience of EV drivers.

Paying for the necessary upgrades will be pricey, but there's a lot of uncertainty here. Li and Jenn came up with a range of anywhere between $6 billion and $20 billion. They put this in context in two ways. The total capital invested in the existing grid is estimated to be $51 billion, so the cost of updating it could be well over a third of its total value. At the same time, the costs will be spread out over decades and only total up to (at most) three times the grid's annual operation and maintenance costs. So in any one year, the costs shouldn't be crippling. All that might be expected to drive the cost of electricity up. But Li and Jenn suggest that the greater volume of electricity consumption will exert a downward pressure on prices (people will pay more overall but pay somewhat less per unit of electricity). Based on a few economic assumptions, the researchers conclude that this would roughly offset the costs of the necessary grid expansion, so the price per unit of electricity would be largely static. The findings have been published in the journal Proceedings of the National Academy of Sciences (PNAS).

Lenovo's latest ThinkPad P1 Gen 7 laptop is set to be the first to use the new LPCAMM2 memory form factor, the successor to SODIMM sticks. From a report: While Lenovo has largely focused on the AI performance of its new laptop, which is equipped with an Intel Core Ultra CPU and Nvidia RTX 3000 Ada GPU, the company also noted that its device was the first in the world to use the LPCAMM2 memory standard. LPCAMM2 uses 64 percent less space than SODIMM and 61 percent less active power, according to Lenovo. This is thanks to it being based on LPDDR5X memory instead of regular DDR5.

Designed specifically for laptops, the LPCAMM2 standard actually has its origins in tech developed by Dell. Simply termed CAMM (Compression Attached Memory Module), it first debuted as a proprietary type of memory in Dell's Precision 7670 in 2022. However, in 2023 the PC giant donated its intellectual property to JEDEC, the organization that standardizes memory technologies. CAMM became LPCAMM2 (Low-Power Compression Attached Memory Module) in September 2023 when JEDEC finally confirmed its specifications. Samsung promptly announced plans to produce LPCAMM2 sticks, and claimed they would have 50 percent more performance and 70 percent more efficiency than their SODIMM-based predecessors. Plus, LPCAMM2 can offer dual-channel memory without requiring a second module.

Today, Framework is the modular repairable laptop company. Tomorrow, it wants to be a consumer electronics company, period. From a report: That's one of the biggest reasons it just raised another $18 million in funding -- it wants to expand beyond the laptop into "additional product categories." Framework CEO Nirav Patel tells me that has always been the plan. The company originally had other viable ideas beyond laptops, too. "We chose to take on the notebook space first," he says, partly because Framework knew it could bootstrap its ambitions by catering to the PC builders and tinkerers and Linux enthusiasts left behind by big OEMs -- and partly because it wanted to go big or go home.

If Framework could succeed in laptops, he thought, it would be able to build almost anything. After five years building laptops, what might Framework add to the portfolio? Patel won't say -- I only get the barest hints, no matter how many different ways I ask. He won't even say if they'll make less or more of a splash than laptops. Framework might choose an "equally difficult" category or might instead try something "a bit smaller and simpler to execute, streamlined now that we have all this infrastructure."

An anonymous reader quotes a report from Ars Technica: Quantum dots are already moving in the premium display category, particularly through QD-OLED TVs and monitors. The next step could be QDEL, short for "quantum dot electroluminescent," also known as NanoLED, screens. Not to be confused with the QLED (quantum light emitting diode) tech already available in TVs, QDEL displays don't have a backlight. Instead, the quantum dots are the light source. The expected result is displays with wider color spaces than today's QD-OLEDs (quantum dot OLEDs) that are also brighter, more affordable, and resistant to burn-in. It seems like QDEL is being eyed as one of the most potentially influential developments for consumer displays over the next two years. If you're into high-end display tech, QDEL should be on your radar.

You may know QDEL as NanoLED because that's what Nanosys, a quantum dot supplier developing the technology, calls it. QDEL has gone by other names, such as QLED -- before Samsung claimed that acronym for LCD-LED TVs that use quantum dots. You may also see QDEL referred to as QD-EL, QD-LED, or EL-QD. As the alphabet soup suggests, there are still some things to finalize with this tech. This article will mostly use the term QDEL, with occasional references to NanoLED. If none of those names sound familiar, it's probably because you can't buy any QDEL products yet. Suppliers suggest that could change in the next few years; Nanosys is targeting 2026 for commercial availability. [...]

Today's OLED screens use OLED material as their light source, with QD-OLED specifically applying quantum dots to convert the light into color. In QLED, the light source is a white backlight; QDEL displays apply electricity directly to quantum dots, which then generate light. QDEL uses a layer of quantum dots sandwiched between an anode and cathode to facilitates the flow of electricity into the quantum dots. QDEL displays have pixels made of a red quantum dot subpixel, green quantum dot subpixel, and -- differing from today's QLED and QD-OLED displays -- blue quantum dot subpixel. QDEL displays use the same quantum dot cores that QD-OLED and QLED products use, [Jeff Yurek, Nanosys' VP of marketing] told me, adding, "The functionalization of the outer layer of the [quantum dots] needs to be changed to make it compatible with each display architecture, but the cores that do the heavy lifting are pretty much the same across all of these."

Because QDEL pixels make their own light and can therefore turn off completely, QDEL displays can deliver the same deep blacks and rich contrast that made OLED popular. But with the use of direct-view quantum dots, stakeholders are claiming the potential for wider color gamuts than we've seen in consumer displays before. With fewer layers and parts, there are also implications for QDEL product pricing, longevity, and even thinness. [...] The fact that quantum dots are already being successfully applied to LCD-LED and OLED screens is encouraging for future QDEL products. QDEL stakeholders claim that the tech could bring efficiencies like lower power consumption and higher brightness than OLED. (Research using a prototype device has recorded quantum dot light-emitting diodes reaching 614,000 nits. Of course, those aren't the type of results you should expect to see in a real-life consumer product.) There's also hope that QDEL could eventually last longer than OLED, especially since QDEL doesn't rely on organic materials that can cause burn-in.

An anonymous reader quotes a report from the Washington Post: In sunny California, solar panels are everywhere. They sit in dry, desert landscapes in the Central Valley and are scattered over rooftops in Los Angeles's urban center. By last count, the state had nearly 47 gigawatts of solar power installed -- enough to power 13.9 million homes and provide over a quarter of the Golden State's electricity. But now, the state and its grid operator are grappling with a strange reality: There is so much solar on the grid that, on sunny spring days when there's not as much demand, electricity prices go negative. Gigawatts of solar are "curtailed" -- essentially, thrown away. In response, California has cut back incentives for rooftop solar and slowed the pace of installing panels. But the diminishing economic returns may slow the development of solar in a state that has tried to move to renewable energy. And as other states build more and more solar plants of their own, they may soon face the same problems.

Curtailing solar isn't technically difficult -- according to Paul Denholm, senior research fellow at the National Renewable Energy Laboratory, it's equivalent to flipping a switch for grid operators. But throwing away free power raises electricity prices. It has also undercut the benefits of installing rooftop solar. Since the 1990s, California has been paying owners of rooftop solar panels when they export their energy to the grid. That meant that rooftop solar owners got $0.20 to $0.30 for each kilowatt-hour of electricity that they dispatched. But a year ago, the state changed this system, known as "net-metering," and now only compensates new solar panel owners for how much their power is worth to the grid. In the spring, when the duck curve is deepest, that number can dip close to zero. Customers can get more money back if they install batteries and provide power to the grid in the early evening or morning.

The change has sparked a huge backlash from Californians and rooftop solar companies, which say that their businesses are flagging. Indeed, Wood Mackenzie predicts that California residential solar installations in 2024 will fall by around 40 percent. Some state politicians are now trying to reverse the rule. "Under the CPUC's leadership California is responsible for the largest loss of solar jobs in our nation's history," Bernadette del Chiaro, the executive director of the California Solar and Storage Association, said in a statement referring to California's public utility commission. But experts say that it reflects how the economics of solar are changing in a state that has gone all-in on the technology. [...] To cope, [California's grid operator, known as CAISO] is selling some excess power to nearby states; California is also planning to install additional storage and batteries to hold solar power until later in the afternoon. Transmission lines that can carry electricity to nearby regions will also help -- some of the lost power comes from regions where there simply aren't enough power lines to carry a sudden burst of solar. Denholm says the state is starting to take the steps needed to deal with the glut. "There are fundamental limits to how much solar we can put on the grid before you start needing a lot of storage," Denholm said. "You can't just sit around and do nothing." Further reading: The Energy Institute discusses this problem in a recent blog post.

Since 2020, the residential electricity rates in California have risen by as much as 40% after adjusting for inflation. While there's been "a lot of finger-pointing about the cause of these increases," the authors note that the impact on rates is multiplied when customers install their own generation and buy fewer kilowatts-hours from the grid because those households "contribute less towards all the fixed costs in the system." These fixed costs include: vegetation management, grid hardening, distribution line undergrounding, EV charging stations, subsidies for low income customers, energy efficiency programs, and the poles and wires that we all rely on whether we are taking electricity off the grid or putting it onto the grid from our rooftop PV systems.

"Since those fixed costs still need to be paid, rates go up, shifting costs onto the kWhs still being bought from the grid."

An anonymous reader shares a report: To accommodate tech companies' pivots to artificial intelligence, tech companies are increasingly investing in ways to power AI's immense electricity needs. Most recently, OpenAI CEO Sam Altman invested in Exowatt, a company using solar power to feed data centers, according to the Wall Street Journal. That's on the heals of OpenAI partner, Microsoft, working on getting approval for nuclear energy to help power its AI operations. Last year Amazon, which is a major investor in AI company Anthropic, said it invested in more than 100 renewable energy projects, making it the "world's largest corporate purchaser of renewable energy for the fourth year in a row."

Bloomberg looks at America's biggest operator of private electrical vehicle charging infrastructure: Amazon. "In a little more than two years, Amazon has installed more than 17,000 chargers at about 120 warehouses around the U.S." — and had Rivian build 13,500 custom electric delivery vans. Amazon has a long way to go. The Seattle-based company says its operations emitted about 71 million metric tons of carbon dioxide equivalent in 2022, up by almost 40% since Jeff Bezos's 2019 vow that his company would eventually stop contributing to the emissions warming the planet. Many of Amazon's emissions come from activities — air freight, ocean shipping, construction and electronics manufacturing, to name a few — that lack a clear, carbon-free alternative, today or any time soon. The company has not made much progress on decarbonization of long-haul trucking, whose emissions tend to be concentrated in industrial and outlying areas rather than the big cities that served as the backdrop for Amazon's electric delivery vehicle rollout...

Another lesson Amazon learned is one the company isn't keen to talk about: Going green can be expensive, at least initially. Based on the type of chargers Amazon deploys — almost entirely midtier chargers called Level 2 in the industry — the hardware likely cost between $50 million and $90 million, according to Bloomberg estimates based on cost estimates supplied by the National Renewable Energy Laboratory. Factoring in costs beyond the plugs and related hardware — like digging through a parking lot to lay wires or set up electrical panels and cabinets — could double that sum. Amazon declined to comment on how much it spent on its EV charging push.
In addition to the expense of the chargers, electric vehicle-fleet operators are typically on the hook for utility upgrades. When companies request the sort of increases to electrical capacity that Amazon has — the Maple Valley warehouse has three megawatts of power for its chargers — they tend to pay for them, making the utility whole for work done on behalf of a single customer. Amazon says it pays upgrade costs as determined by utilities, but that in some locations the upgrades fit within the standard service power companies will handle out of their own pocket.
The article also includes this quote from Kellen Schefter, transportation director at the Edison Electric Institute trade group (which worked with Amazon on its electricity needs). "Amazon's scale matters. If Amazon can show that it meets their climate goals while also meeting their package-delivery goals, we can show this all actually works."

Remember when Apple filed a lawsuit against chip startup Rivos (saying that in one year Rivos hired more than 40 former Apple employees to work on competing system-on-a-chip technology)? Apple settled that suit in February.

And now Tuesday Rivos announced that it raised $250 million, according to Reuters, "in a funding round that will enable it to manufacture its first server chip geared for artificial intelligence," combining a CPU with an AI-accelerating component optimized for LLMs and data analytics. Nvidia gobbled up more than 80% market share of AI chips in 2023. But a host of startups and chip giants have started to launch competing products, such as Intel's Gaudi 3 and Meta's inference chip — both unveiled last week. Rivos is tight-lipped about the specifics of the product, but has disclosed that its plans include designing chips based on the RISC-V architecture, which is an open source alternative to the architectures made by Arm, Intel, and Advanced Micro Devices.. [U]sing the open source alternative means Rivos does not have to pay a license fee to Arm. "RISC-V doesn't have a (large) software ecosystem, so I decided to form a company and then build software-defined hardware — just like what CUDA did with Nvidia," said Lip-Bu Tan, founding managing partner at Walden Catalyst, one of Rivos' investors.
Meanwhile, there's a rumor that Allen Wu, former chief executive of Arm China, has founded a new company that will develop chips based on RISC-V. Tom's Hardware writes: Under the leadership of the controversial Allen Wu, Zhongzhi Chip is reportedly attracting a notable influx of talent, including numerous former employees of Arm, indicating the new company's serious ambitions in the chip sector... [T]he company's operational focus remains partially unclear, with speculation around whether it will primarily engage in its own R&D initiatives or represent Tenstorrent in China as its agent... which develops HPC CPUs and AI processors based on the RISC-V ISA... Based on the source report, Zhongzhi Chip is leveraging its connections and forming alliances with several other leading global RISC-V chip developers.

CNBC visited a small group of bitcoin miners who "set up shop at the site of an extinct volcano" near Kenya's Hell's Gate National Park.

Their mine "consists of a single 500-kilowatt mobile container that, from the outside, looks like a small residential trailer." But what's more interesting is it's operated by a startup called Gridless. (According to its web site Gridless "designs, builds, and operates bitcoin mining sites alongside small-scale renewable energy producers in rural Africa where excess energy is not utilized...") Backed by Jack Dorsey's Block, Gridless electrifies its machines with a mix of solar power and the stranded, wasted energy from a nearby geothermal site. It's one of six mines run by the company in Kenya, Malawi and Zambia, powered by a mix of renewable inputs and working toward a broader mission of securing and decentralizing the bitcoin network... In early 2022, [the three Gridless co-founders] began brainstorming creative solutions for the divide between power generation and capacity, and the lack of access to electricity in Africa. They landed on the idea of bitcoin mining, which could potentially solve a big problem for renewable energy developers by taking their stranded power and spreading it to other parts of the continent.

In Africa, 43% of the population, or roughly 600 million people, lack access to electricity.... Africa is home to an estimated 10 terawatts of solar capacity, 350 gigawatts of hydro and another 110 gigawatts of wind. Some of this renewable energy is being harnessed already, but a lot isn't because building the specialized infrastructure to capture it is expensive. Even with 60% of the best solar resources globally, Africa only has 1% of installed solar PV capacity.

Enter bitcoin miners.

Bitcoin gets a bad rap for the amount of energy it consumes, but it can also help unlock these trapped renewable sources of power. Miners are essentially energy buyers, and co-locating with renewables creates a financial incentive to bolster production. "As often happens, you'll have an overage of power during the day or even at night, and there's nobody to soak that power up," said Hersman. He said his company's 50-kilowatt mining container can "take up whatever is extra throughout the day...." Demand from bitcoin miners on these semi-stranded assets is making renewables in Africa economically viable. The power supplier benefits from selling energy that previously had been discarded, while the energy plants will sometimes lower costs for the customer. At one of the Gridless pilot sites in Kenya, the hydro plant dropped the price of power from 35 cents per kilowatt hour to 25 cents per kWh.

The buildout of capacity is also electrifying households. Gridless says its sites have powered 1,200 houses in Zambia, 1,800 in Malawi and 5,000 in Kenya. The company's mines also have delivered power for containerized cold storage for local farmers, battery charging stations for electric motorcycles and public WiFi points.

Long-time Slashdot reader AmiMoJo shares an article from TechSpot: Zilog is retiring the Z80 after 48 years on the market. Originally developed as a project stemming from the Intel 8080, it eventually rose to become one of the most popular and widely used 8-bit CPUs in both gaming and general computing devices.

The iconic IC device, developed by Federico Faggin, will soon be phased out, and interested parties only have a few months left to place their orders before Zilog's manufacturing partner ends support for the technology... Federico Faggin, an Intel engineer, founded Zilog in 1974 after his work on the Intel 4004, the first 4-bit CPU. The Zilog Z80 was then released in July 1976, conceived as a software-compatible 'extension' and enhancement of the Intel 8080 processor.
Back in 1999 Slashdot was calling Zilog's updated eZ80 "one of the fastest 8-bit CPUs available today, executing code 4 times faster than a standard Z80 operating at the same clock speed."

Another headline, from 2001: Zilog To File For Chapter 11...

The Washington Post reports on a new situation in Virginia: There, massive data centers with computers processing nearly 70 percent of global digital traffic are gobbling up electricity at a rate officials overseeing the power grid say is unsustainable unless two things happen: Several hundred miles of new transmission lines must be built, slicing through neighborhoods and farms in Virginia and three neighboring states. And antiquated coal-powered electricity plants that had been scheduled to go offline will need to keep running to fuel the increasing need for more power, undermining clean energy goals...

The $5.2 billion effort has fueled a backlash against data centers through the region, prompting officials in Virginia to begin studying the deeper impacts of an industry they've long cultivated for the hundreds of millions of dollars in tax revenue it brings to their communities. Critics say it will force residents near the [West Virginia] coal plants to continue living with toxic pollution, ironically to help a state — Virginia — that has fully embraced clean energy. And utility ratepayers in the affected areas will be forced to pay for the plan in the form of higher bills, those critics say. But PJM Interconnection, the regional grid operator, says the plan is necessary to maintain grid reliability amid a wave of fossil fuel plant closures in recent years, prompted by the nation's transition to cleaner power. Power lines will be built across four states in a $5.2 billion effort that, relying on coal plants that were meant to be shuttered, is designed to keep the electric grid from failing amid spiking energy demands. Cutting through farms and neighborhoods, the plan converges on Northern Virginia, where a growing data center industry will need enough extra energy to power 6 million homes by 2030...

There are nearly 300 data centers now in Virginia. With Amazon Web Services pursuing a $35 billion data center expansion in Virginia, rural portions of the state are the industry's newest target for development. The growth means big revenue for the localities that host the football-field-size buildings. Loudoun [County] collects $600 million in annual taxes on the computer equipment inside the buildings, making it easier to fund schools and other services. Prince William [County], the second-largest market, collects $100 million per year.
The article adds that one data center "can require 50 times the electricity of a typical office building, according to the U.S. Department of Energy. "Multiple-building data center complexes, which have become the norm, require as much as 14 to 20 times that amount."

One small power company even told the grid operator that data centers were already consuming 59% of the power they produce...

Michael Larabel reports via Phoronix: With the Framework 16 laptop one of the performance pieces I've been meaning to carry out has been seeing out Linux performs against Microsoft Windows 11 for this AMD Ryzen 7 7840HS powered modular/upgradeable laptop. Recently getting around to it in my benchmarking queue, I also compared the performance of Ubuntu 23.10 to the near final Ubuntu 24.04 LTS on this laptop up against a fully-updated Microsoft Windows 11 installation. The Framework 16 review unit as a reminder was configured with the 8-core / 16-thread AMD Ryzen 7 7840HS Zen 4 SoC with Radeon RX 7700S graphics, a 512GB SN810 NVMe SSD, MediaTek MT7922 WiFi, and a 2560 x 1600 display.

In the few months of testing out the Framework 16 predominantly under Linux it's been working out very well. With also having a Windows 11 partition as shipped by Framework, after updating that install it made for an interesting comparison against the Ubuntu 23.10 and Ubuntu 24.04 performance. The same Framework 16 AMD laptop was used throughout all of the testing for looking at the out-of-the-box performance across Microsoft Windows 11, Ubuntu 23.10, and the near-final state of Ubuntu 24.04. [...]

Out of 101 benchmarks carried out on all three operating systems with the Framework 16 laptop, Ubuntu 24.04 was the fastest in 67% of those tests, the prior Ubuntu 23.10 led in 22% (typically with slim margins to 24.04), and then Microsoft Windows 11 was the front-runner just 10% of the time... If taking the geomean of all 101 benchmark results, Ubuntu 23.10 was 16% faster than Microsoft Windows 11 while Ubuntu 24.04 enhanced the Ubuntu Linux performance by 3% to yield a 20% advantage over Windows 11 on this AMD Ryzen 7 7840HS laptop. Ubuntu 24.04 is looking very good in the performance department and will see its stable release next week.

Apple is doubling down on 8GB of RAM for many of its entry-level Macs, claiming that it's "suitable for many tasks," including browsing, video streaming and even "light" video and image editing. As of this writing, all MacBook Air laptops, the Mac Mini, and the MacBook Pro 14 all start with a base configuration of 8GB RAM -- which can't be upgraded at a later date since the RAM is soldered onto the motherboard. "That might have been OK were it not for the fact that Apple charges a ridiculous $200 to upgrade any of those machines from 8GB to 16GB," notes PC Gamer's Jeremy Laird. Even if an 8GB Mac does some of the previously stated tasks tolerably well, Laird argues that "8GB still isn't acceptable." From the report: That's because a Mac with 8GB can easily run out of memory just browsing the web. That's particularly true with Chrome, which just so happens to be the most popular browser around. Regular Chrome users will know what a memory hog Chrome can be. Right now, I have about 15 tabs open, which is actually pretty low for me. Often, my tab count can blow well past 50 in multiple windows. Handily, Chrome shows you memory usage if you mouse-over a given tab. And three of my current tabs are chewing up over 500MB each. So, that's 1.5GB for just three Chrome tabs. Add a couple more, plus MacOS's underlying memory footprint for just being up and running and you're bang out of RAM.

Overall, I'm using 12.5GB of memory and the only application I have open is Chrome. Oh, and did I mention I'm typing this on a 16GB MacBook Air? I used to have an 8GB Apple silicon Air and to be frank it was a nightmare, constantly running out of memory just browsing the web. That's the point most observers miss. The usual narrative is that 8GB isn't good enough for serious workflows. It isn't but that completely misses the more important point. 8GB isn't even enough for browsing the web.

Jess Weatherbed reports via The Verge: It's alive! A day after announcing it was retiring Atlas, its hydraulic robot, Boston Dynamics has introduced a new, all-electric version of its humanoid machine. The next-generation Atlas robot is designed to offer a far greater range of movement than its predecessor. Boston Dynamics wanted the new version to show that Atlas can keep a humanoid form without limiting "how a bipedal robot can move." The new version has been redesigned with swiveling joints that the company claims make it "uniquely capable of tackling dull, dirty, and dangerous tasks."

The teaser showcasing the new robot's capabilities is as unnerving as it is theatrical. The video starts with Atlas lying in a cadaver-like fashion on the floor before it swiftly folds its legs backward over its body and rises to a standing position in a manner befitting some kind of Cronenberg body-horror flick. Its curved, illuminated head does add some Pixar lamp-like charm, but the way Atlas then spins at the waist and marches toward the camera really feels rather jarring. The design itself is also a little more humanoid. Similar to bipedal robots like Tesla's Optimus, the new Atlas now has longer limbs, a straighter back, and a distinct "head" that can swivel around as needed. There are no cables in sight, and its "face" includes a built-in ring light. It is a marked improvement on its predecessor and now features a bunch of Boston Dynamics' new AI and machine learning tools. [...] Boston Dynamics said the new Atlas will be tested with a small group of customers "over the next few years," starting with Hyundai.

Framework, the company known for designing and selling upgradeable, modular laptops, has struggled with providing up-to-date software for its products. Ars Technica's Andrew Cunningham spoke with CEO Nirav Patel to discuss how the company is working on fixing these issues. Longtime Slashdot reader snikulin shares the report: Driver bundles remain un-updated for years after their initial release. BIOS updates go through long and confusing beta processes, keeping users from getting feature improvements, bug fixes, and security updates. In its community support forums, Framework employees, including founder and CEO Nirav Patel, have acknowledged these issues and promised fixes but have remained inconsistent and vague about actual timelines. [...] Patel says Framework has taken steps to improve the update problem, but he admits that the team's initial approach -- supporting existing laptops while also trying to spin up firmware for upcoming launches -- wasn't working. "We started 12th-gen [Intel Framework Laptop] development, basically the 12th-gen team was also handling looking back at 11th-gen [Intel Framework Laptop] to do firmware updates there," Patel told Ars. "And it became clear, especially as we continued to add on more platforms, that just wasn't a sustainable path to proceed on."

Part of the issue is that Framework relies on external companies to put together firmware updates. Some components are provided by Intel, AMD, and other chip companies to all PC companies that use their chips. Others are provided by Insyde, which writes UEFI firmware for Framework and others. And some are handled by Compal, the contract manufacturer that actually produces Framework's systems and has also designed and sold systems for most of the big-name PC companies. As far back as August 2023, Patel has written that the plan is to work with Compal and Insyde to hire dedicated staff to provide better firmware support for Framework laptops. However, the benefits of this arrangement have been slow to reach users. "[Compal] started recruiting on their side towards the end of last year," Patel told Ars. "And now, just at the beginning of this year, we've been able to get that whole team into place and start onboarding them. And especially after Lunar New Year, which is in early February, that team is now up and running at full speed." The goal, Patel says, is to continuously cycle through all of Framework's actively supported laptops, updating each of them one at a time before looping back around and starting the process over again. Functionality-breaking problems and security fixes will take precedence, while additional features and user requests will be lower-priority. ... snikulin adds: "As a recent Framework 13/AMD owner, I can confirm that it does not sleep properly on a default Windows 11 install. When I close the lid in the evening, the battery is dead the next morning. It's interesting to hear from Linus Sebastian (LTT) on the topic because he is a stakeholder in Framework."

An anonymous reader quotes a report from NPR: An owl. A sharky looking bullet. The Hindu deity Ganesh. The Yin and Yang sign. All painstakingly selected and etched onto a microchip that measures about an inch square. Each microscopic silicon doodle was the handiwork of engineers at Qualcomm Incorporated, a San Diego-based company that creates wireless technology-related products and services. The engineers slipped the drawings into Qualcomm's Q1650 data decoder with care not to disturb any of the chip's functions. They were purposeless etchings, never meant to be uncovered.

These doodles, also known as silicon art, chip graffiti or chip art, and dozens others like it, are remnants of tech history -- from Silicon Valley's infancy to the early 2000s -- when innovation was rapid fire and the tech still had a very human touch. Engineers would add the sketches to their microchip designs in the techie equivalent of signing their artwork. They'd etch them on chips that may end up in your cellphone, laptop or calculator. They spent hours crafting them, even though they were frowned upon by those in the C Suite.

The existence of these doodles came to light decades ago, but social media is discovering them anew. And there is now a small but determined group of online hobbyists working to keep that history alive. They are still cataloguing the miniscule drawings -- many smaller than the width of a human hair and can't be seen without a microscope. These devotees post glossy videos of themselves shucking chips like oysters to see their iridescent insides and the itsy bitsy sketches that may be hidden on them. And they are eagerly saving them from the scrap heap.

Robotics firm Boston Dynamics, owned by Hyundai, has retired its humanoid robot Atlas after a decade, despite significant funding pouring into the category. TechCrunch adds: Boston Dynamics has been focused on commercializing technologies for a number of years now. Hyundai's 2021 acquisition of the firm, coupled with the appointment of Rob Playter as its second-ever CEO, has further accelerated that path. Given the tremendous interest around companies like Agility, Figure, 1X and Apptronik, it stands to reason that -- at the very least -- the Waltham, Massachusetts-based company has -- at the very least -- seriously explored the commercial humanoid category.

Boston Dynamics was, of course, well ahead of the current humanoid robotics curve. Last July marked the 10th anniversary of the bipedal robot's debut. The company teamed with DARPA for Atlas' early development, leading the robot to be heavily incorporated into challenges of the era.

An anonymous reader quotes a report from Electrek: In a major clean energy benchmark, wind, solar, and hydro exceeded 100% of demand on California's main grid for 30 of the past 38 days. Stanford University professor of civil and environmental engineering Mark Z. Jacobson has been tracking California's renewables performance, and he shares his findings on Twitter (X) when the state breaks records. Jacobson notes that supply exceeds demand for "0.25-6 h per day," and that's an important fact. The continuity lies not in renewables running the grid for the entire day but in the fact that it's happening on a consistent daily basis, which has never been achieved before.

At the two-week record mark, Ian Magruder at Rewiring America made this great point on LinkedIn: "And what makes it even better is that California has the largest grid-connected battery storage facility in the world (came online in January ...), meaning those batteries were filling up with excess energy from the sun all afternoon today and are now deploying as we speak to offset a good chunk of the methane gas generation that California still uses overnight." On April 2, the California Independent System Operator (ISO) recommended 26 new transmission projects worth $6.1 billion, with a big number being devoted to offshore wind. In response, Jacobson predicted on April 4 that California will entirely be on renewables and battery storage 24/7 by 2035.

Meanwhile, in Southern California, nonprofit news site Canary Media reports that an old gas combustion plant is being replaced by a "power bank" named Nova.

It's expected to store "more electricity than all but one battery plant currently operating in the U.S." The billion-dollar project, with 680 megawatts and 2,720 megawatt-hours, will help California shift its nation-leading solar generation into the critical evening and nighttime hours, bolstering the grid against the heat waves that have pushed it to the brink multiple times in recent years... The town of Menifee gets to move on from the power plant exhaust that used to join the smog flowing from Los Angeles... And the grid gets a bunch more clean capacity that can, ideally, displace fossil fuels...

Moreover, [the power bank] represents Calpine's grand arrival in the energy storage market, after years operating one of the biggest independent gas power plant fleets in the country alongside Vistra and NRG... Federal analysts predict 2024 will be the biggest-ever year for grid battery installations across the U.S., and they highlighted Calpine's project as one of the single largest projects. The 620 megawatts the company plans to energize this year represent more than 4% of the industry's total expected new additions.

Many of these new grid batteries will be built in California, which needs all the dispatchable power it can get to meet demand when its massive solar fleet stops producing, and to keep pace with the electrification of vehicles and buildings. The Menifee Power Bank, and the other gigawatts worth of storage expected to come online in the state this year, will deliver much-needed reinforcement.
The company says it's planning "a portfolio" of 2,000 megawatts of California battery capacity.

But even this 680-megawatt project consists of 1,096 total battery containers holding 26,304 battery modules (or a total of 3 million cells), "all manufactured by Chinese battery powerhouse BYD, according to Robert Stuart, an electrical project manager with Calpine. That's enough electricity to supply 680,000 homes for four hours before it runs out." What's remarkable is just how quickly the project came together. Construction began last August, and is expected to hit 510 megawatts of fully operational capacity over the course of this summer, even as installation continues on other parts of the plant. Erecting a conventional gas plant of comparable scale would have taken three or four years of construction labor, due to the complexity of the systems and the many different trades required for it, Stuart told Canary Media... That speed and flexibility makes batteries a crucial solution as utilities across the nation grapple with a spike in expected electricity demand unlike anything seen in the last few decades.
The article notes a 2013 Caifornia policy mandating battery storage for its utility companies, which "kicked off a decade-long project to will an energy storage market into existence through methodical policies and regulations, and the knock-on effects of building the nation's foremost solar fleet." Those energy storage policies succeeded in jumpstarting the modern grid battery market: California leads the nation with more than 7 gigawatts of batteries installed as of last year (though Texas is poised to overtake California in battery installations this year, on the back of no particular policy effort but a general openness to building energy projects)... California's interlocking climate regulations effectively rule out new gas construction. The state's energy roadmap instead calls for massive expansion of battery capacity to shift the ample amounts of solar generation into the evening peaks.
"These trends, along with the falling price of batteries and maturing business model for storage, nudged Calpine to get into the battery business, too."
