Apple Adds Hypertension and Sleep-Quality Monitoring To Watch Ultra 3, Series 11
Apple's new Watch lineup introduces blood pressure monitoring, sleep scoring, and upgraded hardware across the Series 11 ($399), Ultra 3 ($799), and SE 3 ($249). Ars Technica reports: The Apple Watch 11 is supposed to be able to alert users about "possible hypertension" by using data from an optical heart rate sensor "to analyze how a user's blood vessels respond to the beats of the heart," per its announcement. According to Apple's presentation, the smartwatch will look for chronic hypertension over 30-day periods. Apple's presentation noted that the Watch Series 11 won't be able to identify all hypertension, but the company said that it expects to notify over 1 million people with undiagnosed hypertension during the feature's first year of availability. The feature is based on machine-learning and training data built from multiple studies examining over 100,000 people combined, Apple noted. Apple said it expects the blood pressure monitoring feature to receive Food and Drug Administration clearance soon and to get approval in 150 regions this month. The new watch will use a 5G modem and also introduce a feature that provides wearers with a "sleep score" that's based on the duration of their sleep, the consistency of their bedtime, how often they awaken from their sleep, and how much time they spend in each sleep stage. The Watch will analyze those factors every night and then provide a breakdown of how each score is calculated. The feature is based on an algorithm tested with 5 million nights of sleep data, Apple said. Other updates include the use of INX glass with ceramic coating that's supposed to make the Watch Series 11 two times more scratch-resistant than its predecessor. The Apple Watch Ultra 3 also debuted with hypertension notifications and sleep scoring, but comes equipped with a brighter edge-viewable OLED display, stronger radios with 5G and satellite support, and a larger 42-hour battery. It starts at $799. Meanwhile, the budget-friendly SE 3 adds the new S10 chip with always-on display, faster charging, and expanded health tracking -- including sleep scores, apnea alerts, and temperature monitoring. It starts at $249.

AirPods Pro 3 Arrive With Heart-Rate Sensing, Live Translation Using Apple Intelligence
Apple has unveiled the AirPods Pro 3 with heart-rate sensing, improved noise cancellation, a more compact case, and upcoming live translation features powered by Apple Intelligence. They'll be available for preorder today at a price of $249. TechCrunch reports: One of the standout features of the AirPods Pro 3 is its heart-rate sensing capability, a first for the AirPods line. This addition will operate similarly to the Powerbeats Pro 2, using LED sensors to provide precise measurements. The collected data will sync with Apple's Fitness app. The active noise cancellation, which reduces external noise, has been significantly improved. Apple says it removes twice the noise compared to Pro 2. A noteworthy upcoming feature is a live translation capability, thanks to Apple's iOS 26 software update. This lets you have conversations in different languages, using your iPhone to translate while the phone plays one language and the AirPods handle the other. Other notable updates include smaller, more comfortable earbuds. Apple now offers foam ear tips in five different sizes, and the company claims it's "the best-fitting AirPods."

Microsoft's Analog Optical Computer Shows AI Promise
Four years ago a small Microsoft Research team started creating an analog optical computer. They used commercially available parts like sensors from smartphone cameras, optical lenses, and micro-LED lights finer than a human hair. "As the light passes through the sensor at different intensities, the analog optical computer can add and multiply numbers," explains a Microsoft blog post. They envision the technology scaling to a computer that for certain problems is 100X faster and 100X more energy efficient — running AI workloads "with a fraction of the energy needed and at much greater speed than the GPUs running today's large language models." The results are described in a paper published in the scientific journal Nature, according to the blog post:At the same time, Microsoft is publicly sharing its "optimization solver" algorithm and the "digital twin" it developed so that researchers from other organizations can investigate this new computing paradigm and propose new problems to solve and new ways to solve them. Francesca Parmigiani, a Microsoft principal research manager who leads the team developing the AOC, explained that the digital twin is a computer-based model that mimics how the real analog optical computer [or "AOC"] behaves; it simulates the same inputs, processes and outputs, but in a digital environment — like a software version of the hardware. This allowed the Microsoft researchers and collaborators to solve optimization problems at a scale that would be useful in real situations. This digital twin will also allow other users to experiment with how problems, either in optimization or in AI, would be mapped and run on the analog optical computer hardware. "To have the kind of success we are dreaming about, we need other researchers to be experimenting and thinking about how this hardware can be used," Parmigiani said. Hitesh Ballani, who directs research on future AI infrastructure at the Microsoft Research lab in Cambridge, U.K. said he believes the AOC could be a game changer. "We have actually delivered on the hard promise that it can make a big difference in two real-world problems in two domains, banking and healthcare," he said. Further, "we opened up a whole new application domain by showing that exactly the same hardware could serve AI models, too." In the healthcare example described in the Nature paper, the researchers used the digital twin to reconstruct MRI scans with a good degree of accuracy. The research indicates that the device could theoretically cut the time it takes to do those scans from 30 minutes to five. In the banking example, the AOC succeeded in resolving a complex optimization test case with a high degree of accuracy... As researchers refine the AOC, adding more and more micro-LEDs, it could eventually have millions or even more than a billion weights. At the same time, it should get smaller and smaller as parts are miniaturized, researchers say.

How Close Are We to Humanoid Robots?
At CES in January, Nvidia's CEO Jensen Huang "stood flanked by 14 humanoid robots from different companies," remembers the Washington Post. But how close are we to real-world robot deployments? Agility Robotics "says its factory is designed to eventually manufacture 10,000 robots a year," the Post adds (with "some" of its robots "already at work in e-commerce warehouses and auto parts factories.") Amazon even invested $150 million in the 10-year-old company (spun out from Oregon State University's robotics lab) in 2022, according to the article, "and has tested the company's robots in its warehouses." The e-commerce revolution has spawned sprawling warehouses across the country where products must be organized and customer orders assembled and shipped, but some human workers have said the repetitive work is low paid and leaves them prone to injury. Agility rents out its robots to warehouse owners it says have struggled to keep their human jobs filled, including logistics company GXO, which uses them at a warehouse for Spanx shapewear in Flowery Branch, Georgia, northeast of Atlanta. The robots pick up baskets of clothing from wheeled robots and walk them over to conveyor belts that take them to other parts of the facility. Agility Chief Business Officer Daniel Diez said facilities like this represent a first step for humanoid robots into gainful employment. "This work gets paid, and we have eyes on large-scale deployments just doing this, and that's what we're focused on," he said. German auto parts company Schaeffler uses Agility robots to load and unload equipment at a factory in Cheraw, South Carolina. Auto part plants have become a favored proving ground for humanoid robots, with Boston Dynamics, the company famous for its videos of back-flipping robots, doing tests with its majority owner, Hyundai. But meanwhile, RoboForce makes a robot that has two arms on a base with four wheels, the article notes, "providing stability and making it possible to lift more weight than a bipedal robot." Humanoid designs make sense "if it is so important to justify the trade-off and sacrifice of other things," RoboForce CEO Leo Ma tells the Post. "Other than that, there is a great invention called wheels." Still, the article argues there's "a new drive to make humanoid robots practical," fueled by "the surge of investment in AI" combined with advancements in robotics that "make humanoid designs more capable and affordable."Years of steady progress have made legged robots better at balancing and stepping through tricky terrain. Improved batteries allow them to operate for longer without trailing industrial power cords. AI developers are adapting the innovations behind services like ChatGPT to help humanoids act more independently... The progress has triggered a frenzy of investment in humanoid robots and made them into a mascot for the idea that AI will soon reorder the world on the scale tech leaders have promised... Venture capitalists have invested over $5 billion in humanoid robotics start-ups since the beginning of 2024, according to financial data firm Pitchbook, and the largest tech corporations are also placing bets... Meta is working on integrating its own AI technology with humanoid robots, and Google researchers are collaborating with Austin-based humanoid robot start-up Apptronik... A host of humanoid robot companies has spawned in China, the world leader in complex manufacturing, where the government is subsidizing the industry. Six of the 14 robots that shared the stage with Nvidia's Huang were made by Chinese companies; five were American. "China's Unitree sells a 77-pound humanoid that stands 4-foot-3 for $16,000..."

'A Very Finnish Thing': Huge Sand Battery Starts Storing Wind Energy In Soapstone
This week Finland inaugurated the world's largest sand battery, according to the Independent, "capable of storing vast amounts of energy generated from renewable sources like solar and wind." The battery "will enable residents to eliminate oil from their district heating network, thereby cutting emissions by nearly 70%," notes EuroNews:Euronews Green previously spoke to the young Finnish founders, Tommi Eronen and Markku Ylönen, who engineered the technology... Lithium batteries work well for specific applications, explains Markku, but aside from their environmental issues and expense, they cannot take in a huge amount of energy. Grains of sand, it turns out, are surprisingly roomy when it comes to energy storage... The sand can store heat at around 500C for several days to even months, providing a valuable store of cheaper energy during the winter... The battery's thermal energy storage capacity equates to almost one month's heat demand in summer and a one-week demand in winter in Pornainen, Polar Night Energy says... Polar Night Energy has big ambitions to take its technology worldwide, and is currently in "active discussions" with both Finnish and international partners. This project (in the Finnish city of Pornainen) "is really important for us because now we can show that this really works," a spokesperson for Polar Night told Clean Technica:The profitability of the sand battery is based on charging it according to electricity prices and Fingrid's reserve markets. Its large storage capacity enables balancing the electricity grid and optimizing consumption over several days or even weeks... "The Pornainen plant can be adjusted quickly and precisely," explained Jukka-Pekka Salmenkaita, vice president of AI and special projects at Elisa Industriq, "and it also has a remarkably long energy buffer, making it well suited for reserve market optimization. Our AI solution automatically identifies the best times to charge and discharge the Sand Battery and allocates flexibility capacity to the reserve products that need it most. Continuous optimization makes it a genuinely profitable investment." Thanks to Slashdot reader AleRunner for sharing the news.

BMW Unveils New iX3 EV With 500-Mile Range, AI-Enabled Software
BMW unveiled its new iX3 — with nearly 500 miles of rangeand ultra-fast charging. The EV news site Electrek reports:To maximize range, BMW gave it a clean, aerodynamic design with very few lines... The BMW iX3 offers an impressive WLTP range of up to nearly 500 miles (800 km). On the EPA scale, it's expected to deliver around 400 miles of range. Based on an 800V architecture, the BMW iX3 can deliver charging speeds of up to 400 kW. According to BMW, that means it can add over 230 miles (370 km) in just 10 minutes. It's also BMW's first EV with bidirectional charging, according to the article. But MotorTrend calls it "BMW's Biggest Reinvention Since the '60s." The decision to move forward in every aspect — design, architecture, technology, software, and manufacturing — was made five years ago... The new Neue Klasse architecture will start out with EVs only, but aspects of this new vision will be adopted by 40 vehicles — SUVs, sedans, coupes, maybe even a supercar — with an assortment of powertrains by the end of 2027. In other words, Neue Klasse will touch and influence everything BMW does going forward... The design philosophy for the Neue Klasse vehicles is that they should look like they skipped an entire generation. From BMW's announcement for the iX3:Physical controls are on hand, including for the windscreen wipers, turn signal indicators, exterior mirrors, volume control, gear selector, parking brake, hazard warning lights, rear window heating and defrost function. Other functions have been optimised for use by touch and voice command or via the multifunction steering wheel... [MotorTrends notes "you must use the screen to adjust the air vents."] The BMW Panoramic Vision projects information across the full width of the windscreen, from A-pillar to A-pillar. The content in the centre and on the front passenger side can be adapted to personal tastes and requirements. Key driving information appears in the driver's field of vision. And above the BMW Panoramic Vision, the BMW 3D Head-Up Display (if specified) can now also show integrated navigation and automated driving displays on the road with spatial depth. The free-cut-design Central Display with matrix backlight technology is located in an ergonomically ideal position next to the steering wheel. On the driver's side, vertically arranged widgets enable fast and direct access to particularly frequently used functions using QuickSelect tech. The new multifunction steering wheel serves as the primary physical control point. Its button panels help the driver and vehicle to work together symbiotically using illuminations, a relief-like surface and haptic feedback. Some details from MotorTrends:There's an avatar for the intelligent personal assistant, activated by saying, "Hey, BMW." The BMW roundel morphs into a blue circle with big, expressive eyes and eyebrows. It looks like an amiable alien that turns to face the person addressing it, and it's programmed to wink, blush, and more, as well as to not stare too long at anyone. The assistant is quick to respond, using Alexa tech and a male or female voice to provide directions, answer questions, and perform functions. MotorTrends adds that the iX3 "is BMW's first software-defined vehicle, meaning it can use over-the-air updates to fix problems and add features and functions, keeping it fresh over its lifetime with software that BMW developed itself." BMW's announcement also notes "the latest systems for automated driving optimise symbiotic human-vehicle interaction..."Whenever the driver wants to accelerate, brake or steer, their inputs merge seamlessly and intuitively with AI-enabled software... The functionality offered by the City Assistant includes traffic light detection, where the car automatically stops and then moves off again.

Bill Gates-Backed Nuclear Fusion Developer Wants to Deploy a Reactor in Japan
"A U.S.-based nuclear fusion developer wants to deploy a reactor in Japan in the late 2030s or early 2040s," reports Bloomberg, "in line with the Asian country's broader plans to adopt the potent, low-carbon energy source."Commonwealth Fusion Systems, which last week announced it raised $863 million from investors including Nvidia, has been in dialogue with Japanese government officials on the use of its technology, CEO Bob Mumgaard said in an interview in Tokyo on Wednesday... Several countries are eyeing the technology for its climate and energy security benefits but only some, like China, the U.S., Russia and South Korea have managed to crack the basics. Japan revised its national strategy in June to support fusion deployment and build a demonstration plant in the 2030s. The article notes that Commonwealth "does not currently have any reactors in operation" — but that Mitsubishi this week invested in the company, in collaboration with a consortium of 12 Japanese companies. From Mitsubishi's announcement:The Japanese Consortium will acquire technical and commercial expertise in policy, regulatory, and the development, construction, operation, and maintenance of ARC [power plant] from CFS's commercialization projects in the United States. In addition, each consortium company will bring together its know-how and expertise and aspire to expedite the commercialization and industrialization of fusion energy power generation in Japan.

Europe Hopes To Join Competitive AI Race With Supercomputer Jupiter
Europe on Friday inaugurated Jupiter, its first exascale supercomputer and the most powerful AI machine on the continent. Built in Germany with 24,000 Nvidia chips, the 500-million-euro system aims to close the AI gap with the US and China while also advancing climate modeling, neuroscience, and renewable energy research. France 24 reports: Based at Juelich Supercomputing Centre in western Germany, it is Europe's first "exascale" supercomputer -- meaning it will be able to perform at least one quintillion (or one billion billion) calculations per second. The United States already has three such computers, all operated by the Department of Energy. Jupiter is housed in a centre covering some 3,600 meters (38,000 square feet) -- about half the size of a football pitch -- containing racks of processors, and packed with about 24,000 Nvidia chips, which are favored by the AI industry. Half the 500 million euros ($580 million) to develop and run the system over the next few years comes from the European Union and the rest from Germany. Its vast computing power can be accessed by researchers across numerous fields as well as companies for purposes such as training AI models. "Jupiter is a leap forward in the performance of computing in Europe," Thomas Lippert, head of the Juelich centre, told AFP, adding that it was 20 times more powerful than any other computer in Germany. [...] Yes, Jupiter will require on average around 11 megawatts of power, according to estimates -- equivalent to the energy used to power thousands of homes or a small industrial plant. But its operators insist that Jupiter is the most energy-efficient among the fastest computer systems in the world. It uses the latest, most energy-efficient hardware, has water-cooling systems and the waste heat that it generates will be used to heat nearby buildings, according to the Juelich centre.

Apple's Vision Pro Gaining Traction in Some Niches of Business
Apple's $3,500 Vision Pro is finding real traction in niche enterprise use, like CAE's pilot training, Lowe's kitchen design visualization, and Dassault's engineering workflows. "Over the last few weeks, I had an opportunity to try out some of those applications, and they are game-changers, albeit within their specific domains," writes Steven Rosenbush via the Wall Street Journal. "Companies should pay attention now to what's going on in these niche markets. Based on what I saw, these systems are having an impact on the way users integrate content development and engineering, which has implications for the way companies approach roles, teams and workflow." From the report: Home-improvement retailer Lowe's has deployed the Vision Pro at five locations in the San Francisco Bay Area and five locations in the Austin, Texas area. Customers use them to visualize how design ideas will look in their actual kitchen. The company plans to scale the effort to 100 of approximately 1,700 stores by the end of the year, eventually ramping up to 400 locations in markets with sufficient scale to justify the investment, Chief Digital and Information Officer Seemantini Godbole told me. [...] Dassault Systemes, the French industrial software company, has long created virtual worlds for commercial use. Scientists, manufacturing experts, product managers and others use its platforms to design and engineer molecules for drug development, as well as data centers, factories, aircraft and electric cars. The 3DExperience platform was launched more than a decade ago, pulling together a range of Dassault brands including 3DExcite on the premise that "everything is going to become an experience," 3DExcite Chief Executive Tom Acland said. In February, Dassault Systemes and Apple announced a collaboration to produce the 3DLive App, which went live February 7. Users include Hyundai, Virgin Galactic and Deutsche Aircraft, he said. [...] Canadian aircraft training company CAE is using Vision Pro to provide pilot training that complements full-motion flight simulator experience required for certification and recurrent checks, according to Chief Technology and Product Officer Emmanuel Levitte. The company has employed mixed reality and immersive training for at least 10 years. The Vision Pro has unlocked new capabilities, he said. The display is as sharp and readable as the controls in a real cockpit, which Levitte found not to be the case with other devices. The haptic feedback and audio quality also contribute to a more realistic training experience, he said. Remote crew members will also be able to be co-located virtually, enabling training that was previously only possible when individuals were physically in the same cockpit, according to Levitte.

America's First Sodium-Ion Battery Manufacturer Ceases Operations
Grady Martin writes: Natron Energy has announced the immediate cessation of all operations, including its manufacturing plant in Holland, Michigan, and plans to build a $1.4 billion "gigafactory" in North Carolina. A company representative cited "efforts to raise sufficient new funding [being] unsuccessful" as the rationale for the decision. When previously covered by Slashdot, comments on the merits of sodium-ion included the ability to use aluminum in lieu of heavier, more expensive copper anodes; a charge rate ten times that of lithium-ion; and Earth's abundance of sodium -- though at least one anonymous coward predicted the cancellation of the project.

Intel Outspends Rivals In R&D: 28% More Than Nvidia, 156% More Than AMD
Intel shelled out $16.5 billion on R&D in 2024, outspending Nvidia by 28% and AMD by 156%, with much of the cash going into chip design, fabrication tech, and the upcoming Nova Lake architecture. "When you compare the R&D expenditures to the amount of revenue, though, the story takes on a very different look," notes PC Gamer. "Intel spent 31% of its net revenue, and 26% for AMD, but Nvidia and Samsung got by on just 10% and 4%, respectively." From the report: An analysis of research and development expenditure by TechInsights was reported by Korea JoongAng Daily, but you can get the numbers yourself by pulling up each company's 2024 financial results. For example, AMD declared that it spent $6.456 billion last year (pdf, page 1) on R&D, whereas Nvidia forked out $12.914 billion. It's worth noting that Nvidia's financial statements are numbered one year ahead of the actual period (FY 2026 is 2025 and so on). Anyway, those figures pale in comparison to how much cash Intel burned through in 2024 to research and develop chip, fabrication technologies, software, and all kinds of tech stuffâ"a staggering $16.546 billion (pdf, page 25). That's 28% more than Nvidia and a frankly unbelievable 156% more than AMD. The nearest non-US semiconductor firm is Samsung Electronics, which spent a reported $9.5 billion on R&D. That would place third, comfortably ahead of AMD, and it strongly suggests that if you have your own foundries for making chips, you need to spend a lot of cash on finding ways to make better processors.

Philips Hue Plans To Make All Your Lights Motion Sensors
Philips Hue is rolling out MotionAware, a new feature that turns its smart bulbs into motion sensors using radio-frequency (RF) Zigbee signals. The upgrade works with most Hue bulbs made since 2014, but requires the new $99 Bridge Pro hub to enable. The Verge reports: To create a MotionAware motion-sensing zone, you need Hue's new Bridge Pro and at least three Hue devices in a room. It works with all new and most existing mains-powered Hue products via a firmware update. That includes smart bulbs, light strips, and fixtures. Portable devices, such as the Hue Go or Table Lamp, and battery-powered accessories, such as Hue switches, aren't compatible. Neither is Hue's current smart plug. [...] "All of the functionality you get with our physical motion sensors -- including turning on when motion is detected or off when there's been no movement for a certain amount of time -- can be configured on motion-aware motion events," says George Yianni, Hue CTO and founder, in an interview with The Verge. "We've done something that's quite a lot better than what else is out there." MotionAware is occupancy sensing, not presence sensing; it requires movement. Yianni says it's comparable to the passive infrared sensing (PIR) Hue's physical sensors use. This means it can be triggered by pets or other motion. A sensitivity slider in the app helps fine-tune detection. According to Yianni, a key benefit over PIR is that a MotionAware zone can cover a larger area than a single PIR sensor, and it's also not limited to line of sight. MotionAware can't sense light levels, which Hue Motion Sensors can, but you can pair a light sensor to a motion zone to feed it that data. The positioning of the lights will also play a role in determining the effectiveness of the motion sensing. "We recommend that the lights surround an area which will roughly define the detection area in which motion will be detected," says Yianni. "It will sense around the lights and in the broader room thanks to reflections, but detection reliability will depend on lots of factors." Beyond lighting automation, MotionAware can also integrate with Hue Secure, Hue's DIY security platform that includes cameras, contact sensors, and a new video doorbell. Motion detection can trigger lights to flash red, activate Hue's new plug-in chime/siren, and send an alert to your phone with a button to call emergency services. [...] MotionAware is built on RF sensing -- a technology that uses wireless signals to "see" a space and detect disruptions within it. The data is then sent to the Bridge Pro, where AI algorithms are applied to figure out what is causing those disruptions, so the system can act accordingly. This is why it's limited to the Bridge Pro, the V2 bridge isn't powerful enough to run those algorithms, says Yianni.

Intel Get $5.7 Billion Early. What's the Government's Strategy?
Intel amended its deal with the U.S. Department of Commerce "to remove earlier project milestones," reports Reuters, "and received about $5.7 billion in cash sooner than planned." "The move will give Intel more flexibility over the funds."The amended agreement, which revises a November 2024 funding deal, retains some guardrails that prevent the chipmaker from using the funds for dividends and buybacks, doing certain control-changing deals and from expanding in certain countries. The move makes the Wall Street Journal wonder what, beyond equity, the U.S. now gets in return, calling government's position "a stake without a strategy."The U.S. has historically shied away from putting money into private business. It can't really outguess the market on where the most promising returns lie. Yet there are exceptions. Sometimes a company or industry risks failing without public support, and that failure would hurt the whole country, not just its shareholders and employees. Intel meets both conditions. It isn't failing, but it is losing money, its core business is in decline, and it lacks the capital and customers needed to make the most advanced semiconductors. If Intel were to fail, it would take a sizable chunk of the semiconductor industrial base with it. At a time of existential competition with China, that is a national emergency... [U.S. Commerce Secretary Howard Lutnick] said as a shareholder, the U.S. would help Intel "to create the most advanced chips in the world." And yet the deal doesn't provide Intel with new resources to accomplish that. Rather, to get the remaining $9 billion, Intel had to give the U.S. equity. This is more like a tax than an investment: Shareholders gave up a 10th of their ownership in return for money the company was supposed to get anyway... Some of the administration's forays into private business do reflect strategic thinking, such as the Pentagon's 15% stake in MP Materials in exchange for investment and contracts that help make the company a viable alternative to China as a supplier of rare-earth magnets for products such as automobiles, wind turbines, jet fighters and missile systems. But more often, companies recoil from government ownership... Though the U.S. stake dilutes Intel's existing shareholders, its stock has held up. There could be several reasons. It eliminates uncertainty over whether the remaining $9 billion in federal funds will be forthcoming... [B]ecause Washington has a vested interest in Intel's share price, investors believe it may prod companies such as Nvidia and Apple to buy more of its chips. But that only goes so far, the article seems to conclude, offering this quote from an analyst Bernstein investment research. "If Intel can prove they can make these leading-edge products in high volume that meets specifications at a good cost structure, they'll have customers lined up around the block. If they can't prove they can do it, what customer will put meaningful volume to them regardless of what pressure the U.S. government brings to bear?" CBS News also notes the U.S. government stake "is being criticized by conservatives and some economic policy experts alike, who worry such extensive government intervention undermines free enterprise."

Wave Energy Projects Have Come a Long Way After 10 Years
They offer "a self-sustaining power solution for marine regions," according to a newly published 41-page review after "pioneering use in wave energy harvesting in 2014". Ten years later, researchers have developed several structures for these "triboelectric nanogenerators" (TENGs) to "facilitate their commercial deployment." But there's a lack of "comprehensive summaries and performance evaluations". So the review "distills a decade of blue-energy research into six design pillars" for next-generation technology, writes EurekaAlert, which points the way "to self-powered ocean grids, distributed marine IoT, and even hydrogen harvested from the sea itself..." By "translating chaotic ocean motion into deterministic electron flow," the team "turns every swell, gust and glint of sunlight into dispatchable power — ushering in an era where the sea itself becomes a silent, self-replenishing power plant." Some insights:- Multilayer stacks, origami folds and magnetic-levitation frames push volumetric power density...three orders of magnitude above first-generation prototypes. - Frequency-complementary couplings of TENG, EMG and PENG create full-spectrum harvesters that deliver 117 % power-conversion efficiency in real waves. - Pendulum, gear and magnetic-multiplier mechanisms translate chaotic 0.1-2 Hz swells into stable high-frequency oscillations, multiplying average power 14-fold. - Resonance-tuned structures now span 0.01-5 Hz, locking onto shifting wave spectra across seasons and sea states. - Spherical, dodecahedral and tensegrity architectures harvest six-degree-of-freedom motion, eliminating orientational blind spots. - Single devices co-harvest wave, wind and solar inputs, powering self-charging buoys that cut battery replacement to zero... Another new wave energy project is moving forward, according to the blog Renewable Energy World:Eco Wave Power, an onshore wave energy technology company, announced that its U.S. pilot project at the Port of Los Angeles has successfully completed operational testing and achieved a new milestone: the lowering of its floaters into the water for the first time. The moment, broadcast live by Good Morning America, follows the finalization of all installation works at the project site, including full installation of all wave energy floaters; connection of hydraulic pipes and supporting infrastructure; and placement of the onshore energy conversion unit. With installation completed, Eco Wave Power has now officially entered the operational phase of its U.S. excursion... [Inna Braverman, founder and CEO of Eco Wave Power] said "This pilot station is a vital step in demonstrating how wave energy can be harnessed using existing marine infrastructure, while laying the groundwork for full-scale commercialization in the United States...." Eco Wave Power's patented onshore wave energy system attaches floaters to existing marine structures. The up-and-down motion of the waves drives hydraulic cylinders, which send pressurized fluid to a land-based energy conversion unit that generates electricity... The U.S. Department of Energy's National Renewable Energy Laboratory estimates that wave energy has the potential to generate over 1,400 terawatt-hours per year — enough to power approximately 130 million homes. Eco Wave Power's 404.7 MW global project pipeline also includes upcoming operational sites in Taiwan, India, and Portugal, alongside its grid-connected station in Israel. Long-time Slashdot reader PongoX11 also brings word of a company building a "simple" floating rig to turn wave motion into electricity, calling it "a steel can that moves water around" and wondering if "This one might work!" The news site TechEBlog points out that "Unlike old-school wave energy systems with clunky mechanical parts, Ocean-2 rocks a modular, flexible setup that rolls with the ocean's flow."At about 10 meters wide [30 feet wide. and 260 feet long!], it is made from materials designed to (hopefully) withstand the ocean's abuse, over some maintenance cycle. It's designed for deep ocean, so solving this technically is the first big challenge. Figuring out how to use/monetize all that cheap energy out in the middle of nowhere will be the next. "Ocean-2 works with the ocean, not against it, so we can generate power without messing up marine life," said Panthalassa's CEO, Dr. Elena Martinez, according to TechEBlog:Tests in Puget Sound, done with Everett Ship Repair, showed it pumping out up to 50 kilowatts in decent conditions — enough juice for a small coastal town. "We're thinking big," Martinez said in a press release. "Ocean-2 is just the start, but we're already planning bigger arrays that could crank out gigawatts..." Looking forward, Panthalassa sees Ocean-2 as part of a massive wave energy network. By 2030, they're aiming to roll out arrays that could power whole coastal cities, cutting down on fossil fuel use.
