Longtime Slashdot reader Qbertino writes: Heise, a German IT news publisher, reports (English version via Google Translate) that the German state of Brandenburg is getting the world's tallest wind turbine, with an overall height of 300 meters (approximately 365 meters including rotor blades), designed to capture so-called third-level winds at higher altitudes. The article also includes a short 3D animation illustrating the construction and its size relative to standard modern wind turbines. The wind turbine uses a dual-framework base instead of a traditional closed tower to access stronger high-altitude winds, aiming to match offshore energy output while keeping onshore operating costs.

According to Heise, the prototype could lead to the installation of up to 1,000 units across Germany -- fitting seamlessly between existing wind farms without needing extra land.

Seagate has released its first heat-assisted magnetic recording hard drives for individual buyers, marking the commercial debut of technology the company has developed for more than two decades. The 30TB IronWolf Pro and Exos M drives cost $600, while 28TB models are priced at $570.

The drives use HAMR technology, which uses tiny lasers to heat and expand drive platter sections within nanoseconds to write data at higher densities. Seagate announced delivery of HAMR drives up to 36TB to datacenter customers in late 2024. The consumer models use conventional magnetic recording technology and are built on Seagate's Mosaic 3+ platform, achieving areal densities of 3TB per disk.

Western Digital plans to release its first HAMR drives in 2027, though it has reached 32TB capacity using shingled magnetic recording. Toshiba will sample HAMR drives for testing in 2025 but has not announced public availability dates.

An anonymous reader quotes a report from Ars Technica: Chinese firms have begun rushing to order Nvidia's H20 AI chips as the company plans to resume sales to mainland China, Reuters reports. The chip giant expects to receive US government licenses soon so that it can restart shipments of the restricted processors just days after CEO Jensen Huang met with President Donald Trump, potentially generating $15 billion to $20 billion in additional revenue this year. Nvidia said in a statement that it is filing applications with the US government to resume H20 sales and that "the US government has assured Nvidia that licenses will be granted, and Nvidia hopes to start deliveries soon." [...]

The H20 chips represent Nvidia's most capable AI processors legally available in China, though they contain less computing power than versions sold elsewhere due to export restrictions imposed in 2022. Nvidia is currently banned from selling its most powerful GPUs in China. Despite these limitations, Chinese tech giants, including ByteDance and Tencent, are reportedly scrambling to place orders for the lesser chip through what sources describe as an approved list managed by Nvidia. "The Chinese market is massive, dynamic, and highly innovative, and it's also home to many AI researchers," Reuters reports Huang telling Chinese state broadcaster CCTV during his visit to Beijing, where he is scheduled to speak at a supply chain expo on Wednesday. "Therefore, it is indeed crucial for American companies to establish roots in the Chinese market."

The resumption of H20 sales marks a shift in US-China technology relations after the chips were effectively banned in April with an onerous export license requirement, forcing Nvidia to take a $4.5 billion write-off for excess inventory and purchase obligations. According to Reuters, Chinese sales generated $17 billion in revenue for Nvidia in the fiscal year ending January 26, representing 13 percent of total sales. Nvidia also announced it will introduce a new "RTX Pro" chip model specifically tailored to meet regulatory rules in the Chinese market, though the company provided no details about its specifications or capabilities.

Plasma Bigscreen, KDE's TV-focused interface, is being revived after years of inactivity thanks to contributor Devin, who overhauled the UI, redesigned the Settings app, improved app launching, and updated key modules. While still in progress -- with features like HDMI-CEC remote support and a virtual keyboard pending -- the project aims to rejoin KDE's official Plasma release schedule, potentially in version 6.5. Neowin reports: If you have not heard of it, Plasma Bigscreen is a Plasma shell for televisions, with original support for the now-defunct Mycroft AI assistant. It used to provide a simple launcher for apps and custom "Mycroft Skills" before development stalled, causing most distributions to drop it. The project was left behind during the big transition to Plasma 6 last year because no one had ported it in time for the megarelease. After a friend of his started poking at the code, Devin stepped in to tackle the much-needed work. [...]

For anyone who wants to test this out, you can do as Devin did by installing Plasma Bigscreen on a Raspberry Pi using postmarketOS, though you would have to compile it yourself or pull from the nightly repos to get the latest changes. Applications like Kodi and VacuumTube (smart TV version of YouTube) work well with remote navigation, and some games like SuperTuxKart are playable. Controller support exists, but getting TV remotes to work over HDMI CEC is still untested. The project is far from finished; it still needs an arrow-navigable virtual keyboard and a clearer long-term direction now that Mycroft is gone. Still, the goal is to get it back into the official Plasma release schedule, possibly for version 6.5.

An anonymous reader quotes a report from Bloomberg: CoreWeave is expanding a data center that is projected to double the electricity needs of a city near Dallas, another example of the strains that artificial intelligence workloads are placing on the US power supply. Local officials have grappled with how to handle the increased stress on the electricity grid from the project, according to a late 2024 presentation and emails seen by Bloomberg. The site is being developed by Core Scientific and will be used by OpenAI in Denton, Texas. Last week, CoreWeave announced it would acquire Core Scientific for about $9 billion, in part, to gain direct control of its data centers aimed at supplying AI work.

Denton, about 50 miles northwest of Dallas, has almost doubled its population in the last 25 years to about 166,000 residents. To meet the spike in AI-related power demand, the city is passing on any extra costs to the data center operator and constructing additional grid infrastructure, Antonio Puente, general manager of local utility Denton Municipal Electric, said in an interview. "To serve the entire load from Core Scientific, we do have some transmission challenges," Puente said. "We will have to make some additional transmission investments." [...] Like some other large AI data center projects, the site in Denton was focused on cryptocurrency mining before pivoting to AI workloads in December. This transition means unrelenting power consumption -- the site will no longer curtail operations when power prices are high -- which will increase grid strain. "Now you're talking about a facility that has to have energy 24 hours a day, 365 days a year," Puente said. That challenge will be mitigated by the addition of backup generators and batteries, he added.

Unlike many large projects, the Denton data center didn't receive local tax exemptions. Officials expect more than $600 million in property and sales tax from the data center expansion, more than double the costs it plans to incur, according to an analysis document seen by Bloomberg. It also anticipates that 135 new jobs will be created, according to the document. The Denton site, which is already being rented by CoreWeave, is Core Scientific's largest planned project at about 390 megawatts of power. It's "utilizing the majority of extra system capacity" in the city, wrote a utility executive in a January email seen by Bloomberg. Any additional large power users will exacerbate overloads on the grid, the executive added. "When fully built out, it will host one of the largest GPU clusters in North America," Core Scientific Chief Executive Officer Adam Sullivan said of the site during a May call. "Denton is a flagship facility."

The report notes that Texas could face electricity shortages as soon as 2026 due to surging power demand from data centers, oil and gas operations, and crypto mining.

An anonymous reader quotes a report from MIT Technology Review: California's statewide power grid operator is poised to become the first in North America to deploy artificial intelligence to manage outages, MIT Technology Review has learned. "We wanted to modernize our grid operations. This fits in perfectly with that," says Gopakumar Gopinathan, a senior advisor on power system technologies at the California Independent System Operator -- known as the CAISO and pronounced KAI-so. "AI is already transforming different industries. But we haven't seen many examples of it being used in our industry."

At the DTECH Midwest utility industry summit in Minneapolis on July 15, CAISO is set to announce a deal to run a pilot program using new AI software called Genie, from the energy-services giant OATI. The software uses generative AI to analyze and carry out real-time analyses for grid operators and comes with the potential to autonomously make decisions about key functions on the grid, a switch that might resemble going from uniformed traffic officers to sensor-equipped stoplights. But while CAISO may deliver electrons to cutting-edge Silicon Valley companies and laboratories, the actual task of managing the state's electrical system is surprisingly analog.

Today, CAISO engineers scan outage reports for keywords about maintenance that's planned or in the works, read through the notes, and then load each item into the grid software system to run calculations on how a downed line or transformer might affect power supply. "Even if it takes you less than a minute to scan one on average, when you amplify that over 200 or 300 outages, it adds up," says Abhimanyu Thakur, OATI's vice president of platforms, visualization, and analytics. "Then different departments are doing it for their own respective keywords. Now we consolidate all of that into a single dictionary of keywords and AI can do this scan and generate a report proactively." If CAISO finds that Genie produces reliable, more efficient data analyses for managing outages, Gopinathan says, the operator may consider automating more functions on the grid. "After a few rounds of testing, I think we'll have an idea about what is the right time to call it successful or not," he says.

Microsoft is testing a new adaptive energy saver mode in Windows 11 that automatically turns energy saver on or off based on system workload instead of battery percentage, aiming to extend laptop battery life without dimming screen brightness. The feature is currently available to Windows Insider testers and expected to roll out later this year. The Verge reports: The energy saver mode in Windows 11 typically dims a display brightness by 30 percent, disables transparency effects, and stop apps running in the background. Non-critical Windows update downloads are also paused, and certain apps like OneDrive, OneNote, and Phone Link may not sync fully while energy saver is enabled. This new adaptive energy saver mode, which will only be available on devices with a battery, will automatically enable or disable without affecting screen brightness. That will make it less noticeable on devices like laptops, tablets, and handhelds.

"Adaptive energy saver is an opt-in feature that automatically enables and disables energy saver, without changing screen brightness, based on the power state of the device and the current system load," explains Microsoft's Windows Insider team.

"GParted Live is a Linux distro with a focused purpose," writes Slashdot reader BrianFagioli. "It exists solely to give users a simple and effective way to manage disk partitions. Whether you're resizing drives, prepping for dual boot, or recovering data, this live operating system has you covered."

But "The 1.7.0 release brings a few key changes, starting with the end of 32-bit support." If you're still using old hardware, you're officially out of luck. This decision follows Debian's move to drop i386 kernel packages from its Sid repository. Because GParted Live is built on Debian Sid, it now ships only in 64-bit (amd64) versions.

This release also includes GParted 1.7.0 along with an updated Linux kernel, version 6.12.37. Another important tweak is the addition of a mechanism that helps avoid random ordering of block devices at boot. That change can prevent users from selecting the wrong disk by mistake, especially in systems with multiple drives.

HGP Storage is a (real) Texas company providing distributed battery-based, utility-scale energy storage systems. Founded in 2013, it has "successfully developed over 20+ sites and closed over 200 MW of distributed energy projects," according to its web site.

And they just teamed up with Enron, reports the Houston Chronicle: The company that took over the defunct Enron brand, led by a "Birds Aren't Real" cofounder [28-year-old Connor Gaydos], held a mostly satirical quarterly earnings call Thursday afternoon but gave updates to an application to become a legitimate Texas energy provider... DJ Withee, chief operating officer and legal counsel at HGP Storage, a company developing utility-scale battery storage farms, was introduced as Enron's vice president of energy service. Withee said he was brought on by Gaydos to set up the customer-facing energy services business.

Enron Energy Texas LLC, a subsidiary of Enron, filed to become a Texas retail electric provider in January. Gaining this designation would allow Enron to sell electricity plans to Texas consumers. "Our business model is actually going to be very simple," Withee said. "We buy wholesale electricity, just like everybody else, but because of our efficiency, because of our use of technology, we are going to have lower costs than our competitors. Lower costs means greater savings that we can pass back to our customers...." According to Withee, Enron's goal is to provide energy at a competitive lower cost that will not only make energy more accessible but also push other Texas retail companies to drop their own prices...

Enron's filing in January included sworn and notarized affidavits from a man named Gregory Forero, who was identified in the documents as vice president of Enron Texas Energy LLC. Forero is the founder and CEO of HGP Storage.
"Forero, who signed his name to three sworn affidavits attesting to the accuracy of the application, could risk perjury charges if the statements of intention to start a legitimate retail electric company are found to be false, according to the Texas Penal Code..."

But does this replace Enron's plan to sell egg-shaped home nuclear reactors?

Electrek reports on the new Omo X, a scooter planned for release in 2026 that's "full of premium tech features that blur the lines between e-scooter and self-driving EV." At its recent launch in Jakarta, the Omo X didn't just sit pretty center stage, it actually drove itself onto the stage using its "Halo Pilot" system, which apparently comes complete with adaptive cruise control, remote summon, self-parking, and even automatic reversing and self-balancing at low speeds. This is legit autonomous behavior previously reserved for cars, now shrunk down and smoothed out for a two-wheeler. Under the hood — or rather, behind the sleek bodywork — Omoway's Halo architecture delivers collision warning, emergency-brake assist, blind spot monitoring, and V2V [vehicle-to-vehicle] communication.

The frame is modular, too. It can be reconfigured in step-through, straddle, or touring posture to suit casual riders, commuters, and motorcycle wannabes alike. That kind of flexibility isn't just a marketing gimmick, but rather it looks purpose-built to capture diverse motorcycle-heavy markets like Indonesia, which counts over 120 million two-wheelers and is quickly transitioning to electric models... It's tech-rich, head-turning, and seems built to evolve with software updates. The remote summon and AI-assisted features could genuinely simplify urban mobility, and tricks like automatically driving itself to a charging station sound legitimately useful...

[But] Omoway's vision here will have to carry extra sensors, actuators, and redundant systems to support those smart functions. With added costs and complexity, will riders in developing markets pay a premium, carry extra maintenance risk, or worry about obsolescence? Much hinges on Omoway's software support and local service networks.
The article reports a projected price around €3,500 (roughly $3,800). "And while Indonesia may have been the launchpad, global markets aren't off the table..."

Lucid Motors set a Guinness World Record for the longest journey by an electric car on a single charge, covering a distance of 749 miles (about 1,205 km), reports New Atlas. "In doing so, Lucid broke the 1,045-km (649-mile) record previously achieved by the Mercedes-Benz EQS450+ in June 2025 by the Japanese car website www.webcg.net/articles/-/52268webCG." The electric vehicle covered this journey between St. Moritz, Switzerland, and Munich, Germany, traveling through highways, secondary roads, and alpine roads — all without a single halt for charging. Given that the vehicle has a 960-km (596-mile) WLTP range, my guess is that the test team must have made good use of favorable road and weather conditions to make the feat possible. With a net elevation decrease of just over 1,310 m (about 4,300 ft) throughout the drive, the EV most certainly benefited from regenerative braking, a rather useful feature that turns downhill momentum back into battery power. Lucid has yet to release official data like average speed or total drive time, but what is apparent is that this was not a high-speed dash but rather a well-planned route to achieve one impressive result...

The Air Grand Touring has two all-wheel drive electric motors with a combined system output of 611 kW (819 horsepower) and 1,200 Nm (885 lb.ft) of torque. Power is provided by an NMC battery, which has a gross energy capacity of 117 kWh (112 kWh usable). Best of all, it can go from 0-60 mph in just three seconds flat... For reference, the almost half-priced BMW i4 and jazzy Porsche Taycan offer less than half the WLTP range of the Lucid Air GT. So, it's not like there's a head-to-head competition out there. Lucid is miles ahead in its class (pun intended!)

Starting at US$112,650, the Air Grand Touring is among the most luxurious sedans on the market right now. But as you can see, it comes at a price. Still, knowing that there is technology to conquer range anxiety is comforting. It might take a while, but there's no reason why we can't expect such range figures from reasonably priced EVs in the near future.

Slashdot reader BrianFagioli shared this report from Nerds.xyz: NVIDIA just put out a new security notice, and if you're running one of its powerful GPUs, you might want to pay attention. Researchers from the University of Toronto have shown that Rowhammer attacks, which are already known to affect regular DRAM, can now target GDDR6 memory on NVIDIA's high-end GPUs when ECC [error correction code] is not enabled.

They pulled this off using an A6000 card, and it worked because system-level ECC was turned off. Once it was switched on, the attack no longer worked. That tells you everything you need to know. ECC matters.

Rowhammer has been around for years. It's one of those weird memory bugs where repeatedly accessing one row in RAM can cause bits to flip in another row. Until now, this was mostly a CPU memory problem. But this research shows it can also be a GPU problem, and that should make data center admins and workstation users pause for a second.

NVIDIA is not sounding an alarm so much as reminding everyone that protections are already in place, but only if you're using the hardware properly. The company recommends enabling ECC if your GPU supports it. That includes cards in the Blackwell, Hopper, Ada, and Ampere lines, along with others used in DGX, HGX, and Jetson systems. It also includes popular workstation cards like the RTX A6000.

There's also built-in On-Die ECC in certain newer memory types like GDDR7 and HBM3. If you're lucky enough to be using a card that has it, you're automatically protected to some extent, because OD-ECC can't be turned off. It's always working in the background. But let's be real. A lot of people skip ECC because it can impact performance or because they're running a setup that doesn't make it obvious whether ECC is on or off. If you're not sure where you stand, it's time to check. NVIDIA suggests using tools like nvidia-smi or, if you're in a managed enterprise setup, working with your system's BMC or Redfish APIs to verify settings.

China "accounts for more than half of global coal use," reports Asia Times, "even as it builds the world's largest solar-panel and EV industries." Much of the world's solar gear is made on fossil power. The International Energy Agency finds that "coal generates over 60% of the electricity used for global solar PV manufacturing," far above coal's ~36% share of typical grids. That is because over 80% of PV factories sit in Chinese provinces like Xinjiang and Jiangsu, where coal dominates the grid.

China has poured over $50 billion into solar factories since 2011, roughly ten times Europe's investment, cutting panel costs by about 80% and fueling a worldwide solar boom. But those panels were produced on coal. In one analysis, they repay their manufacturing CO2 in only months, meaning the emissions were dumped up-front in China's coal plants. Any major disruption to China's coal power or factories (from grid shocks to trade barriers) could thus send ripples through the global PV market.

China's coal and heavy industries also feed its clean-tech supply chain. Coal-fired steel mills supply the aluminum and metal parts for EVs and panels, and coal chemicals provide battery precursors and silicon for solar... At the same time, Chinese oil and gas giants (CNPC, Sinopec) have set up solar, wind and battery divisions, redirecting fossil profits into green ventures.
Another interesting statistic from the article: "In Thailand, Asia's long-time auto hub, Chinese EV brands now command more than 70% of EV sales."

Thanks to Slashdot reader RossCWilliams for sharing the news.

In June 2025, solar power became the leading source of electricity in the EU for the first time, surpassing nuclear and wind, while coal hit a record low. CBC reports: Solar generated 22.1 percent of the EU's electricity last month, up from 18.9 percent a year earlier, as record sunshine and continued solar installations pushed output to 45.4 terawatt hours. Nuclear followed closely at 21.8 percent and wind contributed 15.8 percent of the mix. At least 13 EU countries, including Germany, Spain and the Netherlands, recorded highest-ever monthly solar generation, [data from energy think tank Ember showed on Thursday.]

Coal's share of the EU electricity mix fell to a record low of 6.1 percent in June, compared to 8.8 percent last year, with 28 percent less electricity generated than a year earlier. Germany and Poland, which together generated nearly 80 percent of the 27-country bloc's coal-fired electricity in June, also saw record monthly lows. Coal accounted for 12.4 per cent of Germany's electricity mix and 42.9 percent of Poland's. Spain, nearing a full phase-out of coal, generated just 0.6 per cent of its electricity from coal in the same period.

Wind power also set new records in May and June, rebounding after poor wind conditions resulted in a weak start to the year. But despite record solar and wind output in June, fossil fuel usage in the first half of 2025 grew 13 percent from last year, driven by a 19 percent increase in gas generation to offset weak hydro and wind output earlier in the year. Electricity demand in the EU rose 2.2 percent in the first half of the year, with five of the first six months showing year-on-year increases. The next challenge for Europe's power system is to expand battery storage and grid flexibility to reduce its reliance on fossil fuels during non-solar hours, Ember said in the report.

iFixit has harsh words for Nintendo's $85 Switch 2 Pro controller, calling it a "piss-poor excuse for a controller" due to its difficult repairability, use of outdated drift-prone joysticks, and poor internal accessibility. The Verge reports: Opening the controller requires you to first forcefully remove a faceplate held in place by adhesive tape before a single screw is visible. But you'll need to extract several other parts and components, including the controller's mainboard, before its battery is even accessible. As previously revealed, the Pro 2 is still using older potentiometer-based joysticks that are prone to developing drift over time. They do feature a modular design that will potentially make them easier to swap with third-party Hall effect or TMR replacements, but reassembling the controller after that DIY upgrade will require you to replace all the adhesive tape you destroyed during disassembly. You can watch the full teardown on YouTube.
