The Champlain Hudson Power Express, a $6 billion, 339-mile buried transmission line, will soon deliver Canadian hydropower from Hydro-Quebec to New York City. The project could supply up to 20% of the city's electricity and power roughly one million homes throughout the year. "This is far and away the largest project I have ever worked on," said Bob Harrison, who has worked in infrastructure for 40 years and is the head of engineering for the Champlain Hudson Power Express. "We like to say it's the largest project you'll never see." The New York Times reports: The massive power project, expected to provide energy to a million New York City customers a year, travels underground and underwater, from the northern plains at the Canadian border to the filled-in marshlands of coastal Queens, much of it loosely following the Hudson River. Its construction included the underwater installation of more than two million feet of cable imported from Sweden. It also required special boats, loaded with equipment that could shoot water jets deep into the sediment, to create trenches for the cable. Then, when it came to placing cable beneath the landscape, more than 700 land-use easements were needed, plus an additional 1.55 million feet of cable.

The Champlain Hudson Power Express has found a way to plug into the city, but it wasn't easy. The work included 10 new manholes and more than three miles of new underground circuitry, according to Con Edison, the city's primary electricity provider. "It was literally a hand weave under the streets of Queens," said Jennifer Laird-White, the head of external affairs for Transmission Developers. The hydropower travels from Canada via two buried cables that are as round as cantaloupes. Those lines snake for hundreds of miles under a lake, several rivers (including the Hudson for about 90 miles) and through buried trenches alongside train tracks and roads. The cables resurface in Astoria, Queens, where a converter station shapes, filters and refines the raw power into a product that New Yorkers can consume.

In two cavernous rooms that could be mistaken for "Star Wars" sets, the electricity flows through 30 hanging structures encased in what look like metallic, dinosaurlike exoskeletons. Each one weighs about as much as a small humpback whale and contains microprocessors, thousands of valves and fiber wires. "I am still wowed when I walk into that facility," said Mr. Harrison, the engineer. "I mean, it is just mind-boggling."

More than 30 billion images captured by Pokemon Go players have helped train a visual mapping system developed by Niantic. The technology is now being used to guide delivery robots from Coco Robotics through city streets where GPS often struggles. Popular Science reports: This week, Niantic Spatial, part of the team behind Pokemon Go, announced a partnership with Coco Robotics, a company that makes short-distance delivery robots for food and groceries. Soon, those robot couriers will scoot around sidewalks using Niantic's Visual Positioning System (VPS)-- a navigation tool that can reportedly pinpoint location down to a few centimeters just by looking at nearby buildings and landmarks. Niantic trained that VPS model on more than 30 billion images captured by Pokemon Go users, and claims it will help robots operate in areas where GPS falls short. [...]

Instead of helping users navigate the way that GPS does, VPS determines where someone is based on their surroundings. That makes Pokemon Go particularly useful as a data source, because players had to physically travel to specific locations and point their phones at various angles. That mapping effort got a significant boost in 2020, when the app added what it called "Field Research," a feature prompting players to scan real-world statues and landmarks with their cameras in exchange for in-game rewards. A portion of the data also reportedly came from areas known as "Pokemon battle arenas." Whether players knew it or not, those scans were creating 3D models of the real world that would eventually power the Niantic model. More data means better accuracy, and because Niantic was collecting images of the same locations from many different users, it could capture the same spots across varying weather conditions, lighting, angles, and heights. [...]

The idea is that Coco's robots can use VPS and four cameras mounted around the machine to get a far more precise read on their surroundings. In turn, the well-equipped robot will deliver food on time. On a broader level, Niantic says its partnership with Coco Robotics is part of a longer-term effort to build a "living map" of the world that updates as new data becomes available. Once VPS-equipped delivery robots hit the streets, they will collect even more info that can be fed back into the model to bolster its accuracy further. This kind of continuous, real-world data collection is already central to how self-driving vehicle companies like Waymo and Tesla operate, and is a large part of why that technology has improved so significantly in recent years.

"A new type of battery storage is about to be deployed on the Midwestern grid for the first time," reports Electrek: Sodium-ion battery storage manufacturer Peak Energy and global energy company RWE Americas will pilot a passively cooled sodium-ion battery system in eastern Wisconsin on the Midcontinent Independent System Operator network — the first sodium-ion deployment on that grid. Peak Energy says its technology is specifically designed for grid-scale storage and leverages sodium-ion chemistry's inherent stability. Unlike many lithium-ion systems, sodium-ion batteries don't require active cooling and can operate over a wide temperature range without losing performance.

That simpler design could make a meaningful dent in the cost of storing electricity. According to Peak Energy, its system cuts the lifetime cost of stored energy by an average of $70 per kilowatt-hour. That's roughly half the total cost of a typical battery system today. The company says it achieves those savings by removing energy-hungry cooling systems, eliminating routine maintenance requirements, and reducing the need to overbuild storage capacity to account for battery degradation over time...

If the Wisconsin pilot proves successful, it could open the door to wider adoption of sodium-ion batteries for large-scale energy storage across the US.

The UK's science minister is announcing details of a five-year, £2.5 billion investment in nuclear fusion, reports the Times of London, "including building one of the world's first prototype fusion power plants in Nottinghamshire and developing a UK sector projected to employ 10,000 people by 2030." Despite the potentially transformative impact of fusion, which in theory could provide limitless clean energy and create a £12 trillion global market, no country has managed to use this fledgling technology to generate useable electricity... [T]he UK is backing a spherical tokamak design... investing an initial £1.3 billion into a prototype fusion power plant called Step (Spherical Tokamak for Energy Production) on the site of a decommissioned coal-fired power station at West Burton in Nottinghamshire. Paul Methven, chief executive of the government-owned UK Industrial Fusion Solutions, which is delivering the Step project, said the aim is to get the reactor operating early in the 2040s. "It's quite an aggressive programme," he said. "We need to show that we can achieve genuine 'wall socket' energy — which has not been done before."

On Monday, [science minister] Vallance will also announce £180 million for a facility in Culham, Oxfordshire, to manufacture tritium fuel and £50 million for training 2,000 scientists and engineers in fusion-related disciplines. The government is also buying a £45 million fusion-dedicated AI supercomputer called Sunrise to model plasma physics. Scientists at the UK Atomic Energy Authority last year developed an AI model that can rapidly simulate how the ultra-hot fuel in a fusion power plant will behave, cutting calculations that previously took days down to seconds...

Vallance will also announce new support and collaboration for the many fusion, robotics, engineering and AI start-ups working in Britain, to develop a strong supply chain for a new fusion sector. One of those companies, Tokamak Energy, which spun out from the UK Atomic Energy Authority in 2009, has already built a smaller reactor that has informed the Step design. In March 2022, it became the first private organisation in the world to surpass 100 million degrees Celsius in its reactor.

Slashdot reader SysEngineer does embedded/IoT work, but "I want to pick a single system-on-a-chip architecture family and commit to it across multiple product lines — sensor nodes up through edge gateways... I've been on one platform for years and want to know what embedded engineers are actually running in production before I commit!"

And "the family needs to scale — cheap and small at the low end, capable of running Linux on the bigger variants!"

Their requirements?

• WiFi + BLE required
• LoRaWAN a nice-to-have.
• Low power modes that actually work in the field, not just on the datasheet.
• Full peripheral set — SPI, I2C, UART, ADC, timers, CAN.
• A toolchain and runtime support, support multi threads...

Slashdot reader Gravis Zero is skeptical all the requirements can be met. "If you want embedded, you get embedded. If you want to run a big OS, you get one that will run a big OS."

But Slashdot reader SysEngineer believes "The obvious architecture candidates are ARM, STM, and RISC-V" — and specifically they want to hear your experiences with the RISC-V choices. "What would you standardize on today if you were starting fresh? And how does real-world toolchain and community support hold up compared to the marketing?"

Uber co-founder Travis Kalanick launched a new venture that "will focus on creating 'gainfully employed robots' for the food, mining and transport industries," Bloomberg reports.

"I left Uber in 2017 heartbroken," writes Kalanick on the new company's web site. Kalanick resigned under pressure in 2017, and complains he was "torn away from an idea and a movement that I had poured my life into... I bled, but I did not perish. I got back up and fought my way back into the arena, back to my calling. Back to building. Digitizing the Physical World is my life's work... " Kalanick is remaking his real estate company, City Storage Systems, which owns ghost-kitchen operator CloudKitchens, and renaming it Atoms, according to a manifesto posted on the new company's website. [Bloomberg notes that the company's food robotics division "makes a food assembly machine called Bowl Builder, according to its website."] In addition to its work on food, Los Angeles-based Atoms is expanding into robotics technology for mining and automotive transport. Kalanick said on the livestreamed tech talk show TBPN Friday that Atoms has effectively been in stealth for eight years and has "thousands" of employees....

Kalanick wrote on the Atoms website that the company will make "specialized robots with productive jobs that bring abundance to their owners and society at large." That will include "infrastructure for better food," he wrote, as well as "more productive mines to power Earth's industries" in addition to "wheelbase for robots" in transportation. "The industrial thing is probably our main jam," he said on TBPN. "Once you crack movement in the physical world, there are lots of people who want access to that..." Kalanick also said he was the biggest investor in Pronto, a self-driving trucking startup that currently focuses on closed sites like mines.

It's America's first large-scale offshore wind project, reports WBUR — enough clean energy to power 400,000 homes in Massachusetts from 62 offshore wind turbines generating 800 megawatts.

But it took a while... The plant's first construction delay happened back in 2019, they point out — and then "Just three months ago, when the project was 95% complete, the U.S. Interior Department issued a stop-work order." But after successfully challenging that order in court, and "with a stretch of good weather offshore, the developers behind the $4.5 billion project managed to get over the finish line."

The Associated Press notes it was "one of five major East Coast offshore wind projects the Trump administration halted construction on days before Christmas, citing national security concerns." Developers and states sued, and federal judges allowed all five to resume construction, essentially concluding that the government did not show that the national security risk was so imminent that construction must halt. Another one of the five, Revolution Wind, began sending power for the first time to New England's electric grid on Friday and will scale up in the weeks ahead until it is fully operational.
"That project is nearly complete as well," notes WBUR, "and will eventually be capable of powering up to 350,000 homes."

Plug-in (or "balcony") solar panels can also be hung out a window or be set up in a backyard, reports NPR. They channel energy from the sun straight into a home's electrical outlet, generating enough electricity to power a refrigerator or microwave while "displacing electricity that otherwise would come in from the grid..."

But what's holding up their adoption in America? For the panels to become more widely available in the U.S., state lawmakers are proposing bills that eliminate complicated utility connection agreements, which are required for larger rooftop solar installations and, most utilities say, should apply to plug-in solar too. Those agreements, along with permitting and other installation costs, can double the price of solar panels. Utah enacted the first law, last May, supporting plug-in solar, and now some 30 pieces of similar legislation have been introduced around the United States. [And Virginia seems poised to pass a similar law.]

But the drive toward plug-in solar is facing pushback from electric utilities. They are raising safety concerns and prompting legislators to delay votes on the bills. So far, utilities have won over lawmakers in five states and convinced them to delay votes on plug-in solar bills... Plug-in solar advocates say that safety concerns about the new technology have been addressed and that utilities are really just worried about losing business, because every kilowatt-hour generated by a plug-in solar panel is one less the utility sells to a customer... There are safety risks with any electrical appliance, and it's true that plug-in solar panels present some unique problems. But safety experts also say those issues can be managed....

German utilities expressed many of the same concerns nearly a decade ago when plug-in solar started to become popular in Germany. But with more than a million systems installed, no safety incidents have been reported for customers who used the panels as instructed, according to a research paper funded by the U.S. Department of Energy.

"A few developers found a way, for now, to turn a few of these increasingly mediocre Amazon Show devices into friendly, useful, open computers," writes the co-founder of the gaming/tech news site Aftermath. For under $50 each, he bought some used versions of the devices and tested their instructions, partly to escape the full-screen ads Amazon began showing late last year, and also to overwrite Amazon's locked down Android fork "Fire OS" (and "a similarly neutered version of Linux called Vega OS") Customers who bought these devices and used them for several years were not used to them showing full screen ads, and now they do. People were justifiably pissed. So what do you do when an already evil device gets shittier...? I wiped Fire OS from the device and used ADB sideload to directly load two packages on the device: LineageOS and MindTheGapps. MindTheGapps lets you turn the device into something resembling a traditional Android device, for both good and bad.... It took a few times of wiping the device, but after a few tries it finally worked as intended... I immediately installed the Home Assistant app...

Not only can the hacked Echo Show 8 control my entire smart home, it now plays back my entire local music library as well as any internet radio channels like The Lot Radio and NTS. It can also synchronize with any additional Echo Show running LineageOS in my house using the SendSpin protocol... I would gladly take it any day of the week over most of the devices these companies offer, especially Amazon. It may not be as intuitive as out-of-the-box smart home products, but I don't need my devices to be intuitive, I need them to behave. I had finally found a smart display that wasn't a cop...

The hardware is old and creaky, and after the hack it can only use 1GB of the 2GB of ram. And yet it still manages to feel snappier than the stock hardware. "The amount of telemetry, ads, and general bloat Amazon shoves down our throats definitely doesn't help performance," [XDA Devs Forum user] Rortiz2 told me. "That's actually another reason why we did LineageOS, it kind of gives the device a second life. Even though it's still a bit buggy, it feels way better to use than the stock firmware...." If you want a smart speaker with a display that just runs a stripped-down version of Android that you have full control over, you're going to have a hard time finding it outside of these three specific models unless you cobble something together yourself. It is a deceptively simple thing to desire — the kiosk computer from science fiction that isn't a narc — yet few companies really offer it.
"It should be against the law to not give an end user the ability to consensually load whatever OS or program they want on their device..." the article concludes, arguing that "If we budge on the inalienable right to modify our hardware then we forsake a key part about what makes computers special."

And in the mean time, "There are so many devices that could be put to use rotting in e-waste facilities and thrift stores..."

"The new MacBook Air and MacBook Pro models feature a keyboard change," reports MacRumors: On the U.S. English version of the new MacBook Air and MacBook Pro keyboards, the tab, caps lock, shift, return, and delete keycaps now have glyphs on them. On previous-generation models, these keys are labeled with text instead... Given the U.S. English keyboard layout is the default option for MacBook Air, MacBook Pro, and MacBook Neo models sold in Canada, Australia, New Zealand, and Singapore, this change effectively extends to those countries and a few others.
"Apple already uses glyph-based key labels on several European keyboard layouts," notes The Mac Observer, "including British English versions of the MacBook. Because of this, the design will feel familiar to many users outside the United States."

The change was noticed last week by Chicago-based X.com/YouTube user "Mr. Macintosh", who makes how-to videos about now and old Macs.

BrianFagioli shares a report from NERDS.xyz: Cloud storage company Backblaze has partnered with StorageReview to make a massive dataset containing 314 trillion digits of Pi publicly accessible. The digits were calculated by StorageReview in December 2025 after months of heavy computation designed to stress modern hardware. The dataset now hosted in the cloud weighs in at over 130TB, while the full working dataset used during the calculation reached about 2.1PB when intermediate checkpoints were included. The report notes that the Pi digits have been broken into roughly 200GB chunks to make it more practical for researchers or enthusiasts to download.

Here's what StorageReview founder Brian Beeler said about the project: "Pushing [Pi] to 314 trillion digits was far more than a headline number. It was a sustained, months-long computational challenge that stressed every layer of modern infrastructure, from high core-count CPUs to massive high-speed storage, and it gave us valuable insight into how extreme, real-world workloads behave at scale. Making this dataset available in the Backblaze cloud takes the project a step further by opening access to one of the largest raw outputs ever generated in a single-system calculation. Hosting multi-petabyte files for the broader community is no small feat, and we appreciate Backblaze stepping up to ensure researchers, developers, and enthusiasts can explore and build on this record-setting achievement."

Early benchmarks show the A18 Pro-powered MacBook Neo beating every current x86 CPU in single-core Cinebench performance, including chips from Intel and AMD. Notebookcheck reports: We have performed a couple of benchmarks and were particularly impressed by the single-core performance. Not in the short Geekbench test, but in Cinebench 2024, where a single-core test takes about 10 minutes. The A18 Pro consumes between 3.5-4 Watts in this scenario and scores 147 points. This means it is faster than every other x86 processor in our database, including the two desktop processors Intel Core Ultra 9 285K & AMD Ryzen 9 9950X3D. This also means the MacBook Neo beats every modern mobile processor from AMD, Intel and also Qualcomm, even though the upcoming Snapdragon X2 chips should be a bit faster. The A18 Pro is also slightly faster than Apple's own M3 generation in this scenario. Further reading: ASUS Executive Says MacBook Neo is 'Shock' to PC Industry

Asian governments are implementing emergency measures like four-day workweeks and work-from-home mandates to cope with a fuel shortage triggered by the Iran conflict and the closure of the Strait of Hormuz. "Asia is particularly dependent on oil exports from the Middle East; Japan and South Korea respectively source 90% and 70% of their oil from the region," notes Fortune. From the report: On March 10, Thailand ordered civil servants to take the stairs rather than the elevator, and to work-from-home for the duration of the crisis. It increased the air-conditioning temperature to 27 degrees Celsius, and will tell government employees to wear short-sleeved shirts over suits. (Thailand has about 95 days of energy reserves left, according to Reuters).

Vietnam also called on businesses to let people work-from-home to "reduce the need for travel and transportation." The Philippines is pushing for a four-day work week, and has ordered officials to limit travel "to essential functions only."

South Asia is getting hit hard too. Bangladesh brought forward the Eid-al-fitr holiday, allowing universities to close early in a bid to save fuel. Pakistan also instituted a four-day week for government offices and closed schools. India suspended shipments of liquefied petroleum gas to commercial operators to prioritize supplies for households, leading to worries from hotels and restaurants that they may be forced to close without fuel supplies. Countries across the region are also considering price caps, subsidies, and tapping strategic oil reserves. On Wednesday, the International Energy Agency "unanimously" agreed to release 400 million barrels of oil and refined products from its reserves.

The Associated Press offers a look at the energy supplies that countries hold and when they tap them.

An anonymous reader quotes a report from Reuters: Reducing Europe's nuclear energy sector was a "strategic mistake," European Commission chief Ursula von der Leyen said on Tuesday, as governments grapple with an energy crunch from the Iran war. Europe produced around a third of electricity from nuclear power in 1990 but that has fallen to 15%, she told an event in Paris, leaving it reliant on oil and gas imports whose prices have surged in recent days. Being "completely dependent on expensive and volatile imports" of fossil fuels puts Europe at a disadvantage to other regions, von der Leyen said in a speech. "This reduction in the share of nuclear was a choice. I believe that it was a strategic mistake for Europe to turn its back on a reliable, affordable source of low-emissions power." The report notes that the EU does not directly fund nuclear energy projects because all 27 member states have not unanimously supported the technology. However, von der Leyen said the Commission plans to provide a 200-million-euro guarantee from the EU's carbon market to help attract private investment in innovative nuclear technologies.

ASUS says the MacBook Neo is a "shock" to the Windows PC ecosystem. "In the past, Apple's pricing situation has always been high, so for them to release a very budget-friendly product, this is obviously a shock to the entire industry," said ASUS co-CEO S.Y. Hsu in a Tuesday earnings call. While he expects PC makers to respond, rising AI-driven memory shortages could push hardware prices higher across the industry. PCMag reports: Hsu said he believes all the PC players -- including Microsoft, Intel, and AMD -- take the MacBook Neo threat seriously. "In fact, in the entire PC ecosystem, there have been a lot of discussions about how to compete with this product," he added, given that rumors about the MacBook Neo have been making the rounds for at least a year. Despite the competitive threat, Hsu argued that the MacBook Neo could have limited appeal. He pointed to the laptop's 8GB of "unified memory," or what amounts to its RAM, and how customers can't upgrade it.

He also described the MacBook Neo as a "content consumption" device, similar to an iPad. "This is different from the use case of a mainstream notebook," which can handle more compute-intensive tasks, Hsu said. "How big of an impact [the MacBook Neo] will have on the PC industry will still require some time for us to observe," Hsu said while suggesting it might not gain traction among Windows PC users due to software differences. "Of course, the entire Windows PC ecosystem will push out products to compete against Apple," he added.
