Researchers believe they've discovered a new material structure that can improve the energy storage of capacitors. The structure allows for storage while improving the efficiency of ultrafast charging and discharging. The new find needs optimization but has the potential to help power electric vehicles. * An anonymous reader shared this report from Popular Mechanics: In a study published in Science, lead author Sang-Hoon Bae, an assistant professor of mechanical engineering and materials science, demonstrates a novel heterostructure that curbs energy loss, enabling capacitors to store more energy and charge rapidly without sacrificing durability... Within capacitors, ferroelectric materials offer high maximum polarization. That's useful for ultra-fast charging and discharging, but it can limit the effectiveness of energy storage or the "relaxation time" of a conductor. "This precise control over relaxation time holds promise for a wide array of applications and has the potential to accelerate the development of highly efficient energy storage systems," the study authors write.

Bae makes the change — one he unearthed while working on something completely different — by sandwiching 2D and 3D materials in atomically thin layers, using chemical and nonchemical bonds between each layer. He says a thin 3D core inserts between two outer 2D layers to produce a stack that's only 30 nanometers thick, about 1/10th that of an average virus particle... The sandwich structure isn't quite fully conductive or nonconductive.

This semiconducting material, then, allows the energy storage, with a density up to 19 times higher than commercially available ferroelectric capacitors, while still achieving 90 percent efficiency — also better than what's currently available.

An anonymous reader shared this report from PetaPixel: A photographer and content creator has set the world record for the fastest drone flight after his custom-made aircraft achieved a staggering 298.47 miles per hour (480.2 kilometers per hour). Guinness confirmed the record noting that Luke Maximo Bell and his father Mike achieved the "fastest ground speed by a battery-powered remote-controlled (RC) quadcopter."

Luke, who has previously turned his GoPro into a tennis ball, describes it as the most "frustrating and difficult project" he has ever worked on after months of working on prototypes that frequently caught fire. From the very first battery tests for the drone that Luke calls Peregrine 2, there were small fires as it struggled to cope with the massive amount of current which caused it to heat up to over 266 degrees Fahrenheit (130 degrees Celsius). The motor wires also burst into flames during full load testing causing Luke and Mike to use thicker ones so they didn't fail...

After 3D-printing the final model and assembling all the parts, Luke took it for a maiden flight which immediately resulted in yet another fire. This setback made Bell almost quit the project but he decided to remake all the parts and try again — which also ended in fire. This second catastrophe prompted Luke and his Dad to "completely redesign the whole drone body." It meant weeks of work as the new prototype was once again tested, 3D-printed, and bolted together.

Tim Levin reports via InsideEVs: Two things of note in the electric vehicle world happened today around the same time. First, the Geely Group-owned Chinese EV brand Zeekr debuted on the New York Stock Exchange today at a valuation of around $5.2 billion. Then, around 250 miles south in Washington, D.C., news emerged that the Biden Administration is set to quadruple tariffs on Chinese-made electric cars if they hit American roads. The timing may be purely coincidental. But after this week, one thing feels clearer than ever: the automotive Cold War between China and the West is fully underway, and EVs specifically are at the center of it all.

The Wall Street Journal got the scoop that the White House plans to announce higher tariffs on Chinese clean-energy imports in the coming days. Under the reported new policies, tariffs on Chinese EVs are set to quadruple, rising from the current 25% to a whopping 100%, anonymous sources told the outlet. In theory, that would substantially increase the cost of any Chinese-made EVs on our market, including, potentially, ones sold by known Western and other Asian brands. It's no secret why the U.S. is attempting to push back on Chinese EVs, to say nothing of other clean energy imports from that country like solar panels. China has spent years aggressively building up its capacity to manufacture electric cars. It's developed a stranglehold on the supply chains for lithium-ion batteries and the critical minerals they contain. It has lavished state incentives on both EV production and purchasing. In recent years, the country has emerged as a global EV powerhouse -- and, for the first time ever, an exporter on par with leaders like Japan and Germany.

Many still believe that China's cars are cheap and technologically subpar. But the truth is China has learned to build cars very, very well, as InsideEVs' own Kevin Williams discovered during a recent trip to the Beijing auto show. China's homegrown electrified vehicles range from the inexpensive -- some, like the BYD Seagull, cost less than $10,000 in their home market -- to higher-end, luxury-focused offerings like the Yangwang U8, a kind of plug-in hybrid competitor to the Mercedes G-Class that can "float" on water. From batteries to software, most are incredibly advanced. Car companies and policymakers in the U.S. (and Europe) say these cars pose a real threat to our nascent EV market, where many options still remain unaffordable and things like batteries and software are works in progress. In response, European Union officials have also launched investigations into Chinese imports that could lead to stronger tariffs. "In effect, the tariffs may end up buying the U.S. some time, rather than being a permanent solution here," concludes Levin. "After all, as Kevin Williams pointed out after going to Beijing: all of these crackdowns aren't guaranteed to yield better cars from Ford, General Motors and the rest."

According to the WSJ, the new tariffs on Chinese goods will also apply to solar panels, batteries and critical battery minerals. They're expected to be announced as soon as next week.

Jess Weatherbed reports via The Verge: At least 224 people with diabetes have reported injuries linked to a defective iOS app that caused their insulin pumps to shut down prematurely, according to the US Food and Drug Administration (FDA). On Wednesday, the agency announced that California-based medical device manufacturer Tandem Diabetes Care has issued a recall for version 2.7 of the iOS t:connect mobile app, which is used in conjunction with the company's t:slim X2 insulin pump. Specifically, the recall relates to a software issue that can cause the app to repeatedly crash and relaunch, resulting in the pump's battery being drained by excessive Bluetooth communication.

This battery drain can cause the pump to shut down "earlier than typically expected" according to Tandem, though the pump will notify users of an imminent shutdown via an alarm and low-power alert. The company has notified customers to update the mobile app to version 2.7.1 or later, which should fix the defective software. While no physical recall is taking place, the FDA has identified this as a "Class I" recall -- the most serious type, as it relates to issues with products that can potentially cause serious injuries or death. No deaths linked to the issues have been reported as of April 15th. Tandem is encouraging pump users to take particular care when they sleep as it's easier to miss battery depletion warnings, and is asking impacted customers to confirm they have been notified of the recall via this online form. For any other questions or concerns about the insulin pump recall, customers should contact Tandem Diabetes Care directly.

The Pixel 8A is officially here. The 8A gets Google's latest processor, adds a bunch of new AI features, and still starts at $499 in the US. But the very best news is that the 8A adopts the Pixel 8 and 8 Pro's seven years of software support, which is just unheard of in a midrange phone. From a report: The 8A retains the same general shape and size as its predecessor. But its 6.1-inch screen gets a couple of significant updates: the top refresh rate is now 120Hz, up from 90Hz, and the panel gets up to 40 percent brighter, up to 2,000 nits in peak brightness mode. They're important upgrades, especially since the 8A's main competition in the US, the OnePlus 12R, comes with an excellent display.

It comes with the same generative AI photo and video features that made a splash on the Pixel 8 and 8 Pro, including Best Take, Magic Editor, and Audio Magic Eraser. Circle to Search is also available, and the 8A will be able to run Google's mobile-optimized on-device AI model, Gemini Nano. As on the Pixel 8, it'll be a developer option delivered via feature drop. Other specs are either unchanged or slightly boosted compared to the last generation. There's still 8GB of RAM and 128GB of storage, though there's now a 256GB option. Camera hardware is unchanged from the 7A, including a stabilized 64-megapixel main sensor. There's an IP67 rating, consistent with the 7A, and battery capacity is a little higher at 4,492mAh compared to 4,385mAh. Wireless charging is available via Qi 1.3 at up to 7.5W -- no Qi2 here.

An anonymous reader quotes a report from Wired: In April, Apple sent notifications to iPhone users in 92 countries, warning them they'd been targeted with spyware. "Apple detected that you are being targeted by a mercenary spyware attack that is trying to remotely compromise the iPhone associated with your Apple ID," the notification reads. Users quickly took to social media sites including X, trying to work out what the notification meant. Many of those targeted were based inIndia, but others in Europe also reported receiving Apple's warning. Weeks later, little is still known about the latest iPhone attacks. Former smartphone giant Blackberry, now a security firm, has released research indicating they are linked to a Chinese spyware campaign dubbed "LightSpy," but Apple spokesperson Shane Bauer says this is inaccurate.

While Apple says the latest spyware notifications aren't linked to LightSpy, the spyware remains a growing threat, particularly to people who may be targeted in Southern Asia, according to Blackberry's researchers. Described as a "sophisticated iOS implant," LightSpy first emerged targeting Hong Kong protesters in 2020. However, the latest iteration is much more capable than the first. "It is a fully-featured modular surveillance toolset that primarily focuses on exfiltrating victims' private information, including hyper-specific location data and sound recording during voice over IP calls," the researchers wrote. April's warnings were not the first time Apple has issued notifications of this kind. The iPhone maker has sent out alerts to people in over 150 countries since 2021 as spyware continues to target high-profile figures across the globe.

Spyware can be weaponized by nation-state adversaries -- but this is relatively rare and expensive. Its deployment is typically highly targeted against a very specific group of people, including journalists, political dissidents, government workers, and businesses in certain sectors. "Such attacks are vastly more complex than regular cybercriminal activity and consumer malware, as mercenary spyware attackers apply exceptional resources to target a very small number of specific individuals and their devices," Apple wrote in an advisory in April. "Mercenary spyware attacks cost millions of dollars and often have a short shelf life, making them much harder to detect and prevent. The vast majority of users will never be targeted by such attacks." Plus, Apple says its Lockdown Mode feature can successfully protect against attacks. "As we have said before, we are not aware of anyone using Lockdown Mode being successfully attacked with mercenary spyware," Bauer says. Still, for those who are targeted and caught unaware, spyware is extremely dangerous. There are a number of ways to protect yourself against spyware and zero-click exploits in particular:

1. Regularly Update Devices: Keep your devices updated to the latest software to protect against known vulnerabilities.
2. Restart Devices Daily: Regularly restarting your device can help disrupt persistent spyware infections by forcing attackers to reinfect the device, potentially increasing their chances of detection.
3. Disable Vulnerable Features: Consider disabling features prone to exploits, such as iMessage and FaceTime, especially if you suspect you're a target for spyware.
4. Use Multifactor Authentication and Secure Sources: Employ multifactor authentication and only install apps from verified sources to prevent unauthorized access and downloads.
5. Monitor for Indicators: Be vigilant for signs of infection such as battery drain, unexpected shutdowns, and high data usage, though these may not always be present with more sophisticated spyware.
6. Seek Professional Help: If you suspect a spyware infection, consider professional assistance or helplines like Access Now's Digital Security Helpline for guidance on removal.
7. Utilize Advanced Security Features: Activate security features like Apple's Lockdown Mode, which limits device functionality to reduce vulnerabilities, thus safeguarding against infections.

The Rabbit R1 is one of the first standalone AI companion devices to hit the market, offering the ability to translate languages, identify objects in your environment, and order DoorDash, among other things. It's been in the news last week for its all around poor reviews that cite poor battery life, painfully slow responses, and missing features (sound familiar?). Now, it's been confirmed that the Rabbit R1 is powered by an Android app that can run on existing Android phones. Android Authority reports: What ended up souring a lot of people's opinions on the product was the revelation -- in an Android Authority original report -- that the R1 is basically an Android app in a box. Many consumers who believed that the product would be better suited as a mobile app felt validated after our report, but there was one stickler in it that we needed to address: how we got the R1 launcher up and running on an Android phone. See, in our preliminary report, we mentioned that the Rabbit R1's launcher app is intended to be preinstalled in the firmware and be granted several privileged, system-level permissions. While that statement is still true, we should've clarified that the R1 launcher doesn't actually need those permissions. In fact, none of the system-level permissions that the R1 launcher requests are at all necessary for the app to perform its core functionality.

To prove this, we got the Rabbit R1 launcher up and running again on a stock, unrooted Android device (a Xiaomi 13T Pro), thanks to help from a team of reverse engineers including ChromMob, EmilyLShepherd, marceld505, thel3l, and uwukko. We were able to go through the entire setup process as if our device was an actual Rabbit R1. Afterwards, we were able to talk to ChatGPT, use the Vision function to identify objects, play music from Spotify, and even record voice notes. As demonstrated in our hands-on video at the top of this article, all of the existing core functionality that the Rabbit R1 offers would work as an Android or even iOS app. The only functions that wouldn't work are unrelated to the product's core functionality and are things your phone can already do, such as powering off or rebooting the device, toggling Bluetooth, connecting to a cellular or Wi-Fi network, or setting a screen lock.

During our research, Android Authority was also able to obtain a copy of the Rabbit R1's firmware. Our analysis reveals that Rabbit did not make significant modifications to the BSP (Board Support Package) provided by MediaTek. The R1, in fact, still ships with all the standard apps included in AOSP, as well as the many apps provided by MediaTek. This is despite the fact that none of these apps are needed nor ever shown to the user, obviously. Rabbit only made a few changes to the AOSP build that MediaTek provided them, such as adding the aforementioned R1 launcher app, adding a fork of the open-source "AnySoftKeyboard" app with a custom theme, adding an OTA updater app, and adding a custom boot animation. [...] Yes, it's true that all the R1 launcher does is act as a local client to the cloud services offered by Rabbit, which is what truly handles the core functionality. It's also true that there's nothing wrong or unusual with companies using AOSP for their own hardware. But the fact of the matter is that Rabbit does little to justify its use of custom hardware except by making the R1 have an eye-catching design.

Natron Energy, a pioneer in sodium-ion battery technology, has officially commenced mass production of its lithium-free sodium batteries in its Holland, Michigan facility, offering an alternative energy storage solution with benefits such as faster cycling, longer lifespan, and safer usage compared to lithium-ion batteries. New Atlas reports: Not only is sodium somewhere between 500 to 1,000 times more abundant than lithium on the planet we call Earth, sourcing it doesn't necessitate the same type of earth-scarring extraction. Even moving beyond the sodium vs lithium surname comparison, Natron says its sodium-ion batteries are made entirely from abundantly available commodity materials that also include aluminum, iron and manganese. Furthermore, the materials for Natron's sodium-ion chemistry can be procured through a reliable US-based domestic supply chain free from geopolitical disruption. The same cannot be said for common lithium-ion materials like cobalt and nickel.

Sodium-ion tech has received heightened interest in recent years as a more reliable, potentially cheaper energy storage medium. While its energy density lags behind lithium-ion, advantages such as faster cycling, longer lifespan and safer, non-flammable end use have made sodium-ion an attractive alternative, especially for stationary uses like data center and EV charger backup storage. [...] Natron says its batteries charge and discharge at rates 10 times faster than lithium-ion, a level of immediate charge/discharge capability that makes the batteries a prime contender for the ups and downs of backup power storage. Also helping in that use case is an estimated lifespan of 50,000 cycles.

A new battery from Energizer comes with "color alert technology" to alert parents if their child has swallowed one. When the coin lithium battery comes into contact with saliva, it activates a blue dye "so parents and caregivers know that medical attention could be required," reports the New York Times. The battery also features more secure packaging and a nontoxic bitter coating. From the report: The new coin lithium battery features more secure packaging, a nontoxic bitter coating to discourage swallowing and "color alert technology" that activates a blue dye when the battery comes into contact with moisture, like saliva, so parents and caregivers know that medical attention could be required. The new battery was announced in a video last week by Energizer and Trista Hamsmith, whose 18-month-old daughter died after swallowing a button battery from a remote control. Ms. Hamsmith founded a nonprofit organization focused on children's safety, successfully advocated for legislation, known as Reese's Law, that requires a secure compartment of the batteries in products that use them as well as stronger warning labels on all packaging, and is now working to make the batteries themselves safer.

Ingested coin or button batteries result in thousands of emergency hospital visits each year, according to the U.S. Consumer Product Safety Commission, which notes that "the consequences of a child swallowing a battery can be immediate, devastating and deadly." "A button cell battery can burn through a child's throat or esophagus in as little as two hours if swallowed," according to the agency. Secure packaging and bitter coatings for batteries have long existed, but "the massive breakthrough here is the color alert technology, which helps give caretakers that indicator that something has happened," Jeff Roth, the global category leader for batteries at Energizer, said in an interview on Wednesday. "The most significant part about this is getting help early in the process," he said. "That's really what the color alert technology allows the family to do."

AmiMoJo shares a report from Tech Times: China has reached a major landmark in green transportation with the launch of the world's largest fully electric container ship. Developed and manufactured by China Ocean Shipping Group (Cosco), the vessel is now operating a regular service route between Shanghai and Nanjing, aiming to reduce emissions significantly along its journey. The Greenwater 01, an all-electric container ship, is positioning itself to be a shipping industry pioneer. Equipped with a main battery exceeding 50,000 kilowatt-hours, the vessel can accommodate additional battery boxes for longer voyages. These battery boxes, each containing 1,600 kilowatt-hours of electricity and similar in size to standard 20-foot containers, provide flexibility in extending the ship's travel range. With 24 battery boxes onboard, the Greenwater 01 can complete a journey consuming 80,000 kilowatt-hours of electricity. This is equivalent to saving 15 tons of fuel compared to a standard container ship, highlighting the efficiency of electric propulsion systems. According to Cosco, the vessel can reduce CO2 emissions by 2,918 tons per year, which is equivalent to taking 2,035 family cars off the road or planting 160,000 trees.

Oakland, California is now home to "the first commercial hydrogen fuel station for big-rig trucks in the United States," according to the Los Angeles Times — serving 30 hydrogen fuel-cell trucks.

The newspaper says the facility "could mark the start of a nationwide network for fuel-cell truck refueling. It could also flop." Hydrogen fuel is expensive — as much as four times more expensive than gasoline or diesel fuel. The fuel cells, which drive electric motors to drive the truck, are enormously expensive as well.... The vehicles themselves are expensive too. Both battery electric and hydrogen fuel-cell trucks can cost three times as much or more than a $120,000 diesel truck. Those buying the trucks can qualify for state and federal subsidies to make up most of the upfront costs.
But government regulations may spark some demand: New diesel truck sales will be outlawed in California by 2036. Only zero-tailpipe-emission new trucks will be allowed. Already, zero-emission requirements are in place for trucks that enter ocean ports. And only two technologies are available to achieve that goal: battery electric trucks and hydrogen fuel-cell trucks. "We believe a good portion of those will be hydrogen vehicles," said Matt Miyasato, chief of public policy for hydrogen fuel distributor FirstElement Fuel. FirstElement, through its True Zero brand fueling stations, is the largest hydrogen vehicle fuel distributor in the U.S...

Battery electric is gaining a strong foothold in the medium-sized delivery truck market, but hydrogen could have a leg up for long-haul trucking. While a fuel cell is comparable in size to a diesel engine, a battery big enough for long-haul trucks adds weight and size and cuts down on the total freight load the truck can deliver. And while an electric truck battery can take hours to recharge, the refill time for hydrogen is more comparable to filling up with diesel fuel.

"In less than 15 years, battery costs have fallen by more than 90%," according to a new report from the International Energy Agency, "one of the fastest declines ever seen in clean energy technologies."

And it's expected to get even cheaper, reports Reuters: An expected sharp fall in battery costs for energy storage in coming years will accelerate the shift to renewable energy from fossil fuels, the International Energy Agency (IEA) said on Thursday... The total capital costs of battery storage are due to tumble by up to 40% by 2030, the Paris-based watchdog said in its Batteries and Secure Energy Transitions report.

"The combination of solar PV (photovoltaic) and batteries is today competitive with new coal plants in India," said IEA Executive Director Fatih Birol. "And just in the next few years, it will be cheaper than new coal in China and gas-fired power in the United States. Batteries are changing the game before our eyes." [...] The global market for energy storage doubled last year to over 90 gigawatt-hours (GWh), the report said...

The slide in battery costs will also help provide electricity to millions of people without access, cutting by nearly half the average electricity costs of mini-grids with solar PV coupled with batteries by 2030, the IEA said.
The Los Angeles Times notes one place adopting the tech is California: Standing in the middle of a solar farm in Yolo County, [California governor] Newsom announced the state now had battery storage systems with the capacity of more than 10,000 megawatts — about 20% of the 52,000 megawatts the state says is needed to meet its climate goals.
Although Newsom acknowledged it isn't yet enough to eliminate blackouts...

This year Dell moved to soldered RAM for its XPS 14 and 16, writes Digital Trends, which "makes it impossible to upgrade, or even repair."

"This was a big change from the past, where the XPS 15 and 17 were both celebrated for their upgradability." Of course, Dell isn't the first to make the transition. In fact, they're one of the last, which is what makes the decision so much tougher to swallow. Where soldered RAM was previously limited to just MacBooks and ultrabooks, it's now affecting most high-performance laptops for gaming as well. Even the fantastic ROG Zephyrus G14 moved to soldered memory this year.
After two months of research, the article's author acknowledges "there are tangible benefits to companies using soldered RAM, and all the people I spoke to while writing this agree that they outweigh the downsides, but how that applies to the end-user is a bit more complicated." If there's one thing and one thing only that soldered RAM is indisputably good for, it's saving space. [Haval Othman, a senior director of experience engineering at HP] explained the benefits, saying: "If battery life, mobility, form factor (thin and light), and power efficiency are my priority among other design choices, then my mind immediately goes to soldered RAM; because that's where soldered RAM can be beneficial and power-efficient, which will lead to longer battery life. Plus, it's going to give me more space on the motherboard, so I can design the product thinner and lighter. [...] If we want a thin product, the trade-off is soldering more of the devices onto the board."

This tracks. In a laptop, there's only so much space that can be used for components, and that free space grows smaller by the year to make ultrabooks possible. They're an industrywide trend that was first popularized by Apple, and the rest of the laptop manufacturing world quickly caught on. Each year, laptops are released thinner and lighter, and that means having to squeeze the components together in new, innovative ways... Soldering the memory down onto the motherboard means that it can be attached almost anywhere within the laptop instead of being slotted into a specific part of it. It effectively makes the laptop thinner by cutting back on the space that the RAM module takes up. The space saved by soldering memory can be used for other things, such as a bigger battery....

All three companies that I spoke to stress the form factor much more than any tangible cost benefits... Stuart Gill, director of global media relations, campaigns, and corporate content [said] "Both soldered and socketed RAM designs are now quite mature. As a result, we see no impact on the manufacturing process and, therefore, the cost to the consumer."
SO-DIMM chips also have "relatively limited bandwidth," according to HP's Othman, "while when you solder the memory chips onto the board, you can build it for a much wider bandwidth."

But the article ends by looking to the future. "The good news is that SO-DIMM memory might eventually be replaced by the CAMM2 standard." Recently approved by JEDEC, CAMM2 is said to be significantly thinner, and it'll be available both in soldered and non-soldered variants. Using CAMM2 will allow laptops to stack up to 128GB of RAM, and the frequencies are said to be going up, too. CAMM2 can also activate dual-channel memory with just a single module.

Japan's moon lander "has woken up again," reports the Register, "having survived three lunar nights." A post on social media from the lander's X account confirmed that once more, Japan's Smart Lander for Investigating Moon (SLIM) had defied the odds and snapped a picture of the lunar surface using its navigation camera. SLIM was revived a few weeks ago, after a second lunar night. However, with telemetry showing that some of the electronics (temperature sensors) and battery cells were malfunctioning, the chances of the lander making it through a third lunar night seemed remote.

Yet against all odds, SLIM has stirred once more on the lunar surface despite lacking heaters to keep its electronics warm.

Jonathan M. Gitlin reports Ars Technica: Honda announced today that it will spend $11 billion to expand its electric vehicle manufacturing presence in North America. The Japanese automaker already has a number of factories in the US, Mexico, and Canada, and it's this last one that will benefit from the expansion, with four EV-related plants planned for Ontario. Honda says it has begun evaluating requirements for what it's calling an "innovative and environmentally responsible" EV factory and a standalone EV battery plant in Alliston, Ontario, which is already home to Honda's two existing Canadian manufacturing facilities.

Additionally, the automaker wants to set up another two sites as joint ventures. One will be a plant that processes cathode active materials and their precursors -- the various elements like nickel and manganese that are combined with lithium in lithium-ion batteries -- set up in a partnership with POSCO Future M, a South Korean battery material and chemical company. (POSCO is already working with General Motors on another joint venture battery precursor material facility in Betancour, Quebec, that is supposed to become operational in 2026.) A second joint venture will be a partnership with Asahi Kasei, which will manufacture battery separators, the material that keeps the anode and cathode apart. The locations of these two joint ventures have not yet been announced.

Honda thinks it will be able to start making EVs in Ontario in 2028 and says the assembly plant will have the capacity to build 240,000 EVs per year. Meanwhile, the battery plant is planned to have an annual output of 36 GWh.

Toyota's Mirai, a hydrogen-powered Fuel Cell EV initially heralded as the future of driving, has faced significant challenges due to inadequate hydrogen fueling infrastructure. As chronicled by InsideEVs, many owners have become disillusioned with the vehicle's high operational costs, unreliable refueling options, and significant depreciation, prompting lawsuits and calls for buybacks. Longtime Slashdot reader whoever57 writes: Toyota Mirai owners are fed up and disillusioned. Hydrogen fuel pumps are hard to find and, rather than new pumps opening, they are closing down. Owners feel misled about the costs and availability of hydrogen fuel stations. Even if a Mirai owner can find a fuel station, it may not be operating. Moreover, refueling is frequently a long and problematic process, with pumps taking over an hour to fill a tank and cars getting stuck to the fuel pump for hours. It would be quicker to charge a battery EV. Naturally, resale values of these cars are plummeting. Even without those problems, once the complimentary hydrogen fuel supply that Toyota gives new owners expires or runs out, the cost of hydrogen fuel becomes quite expensive. "Not in my wildest dreams or nightmares would I expect a purchase from a giant car company like Toyota would turn out to be such a terrible experience," said owner Shawn Hall. "The entire H2 vehicle experience is an experiment that is failing. I didn't expect to buy a vehicle from Toyota and feel duped, cheated, and misled."

Another user wrote on Reddit: "We all need to realize that we bought a vehicle that had, at best, a questionable future. Unfortunately in this instance, the gamble didn't pay off, and the technology of hydrogen fuel cell vehicles does not appear to be something the vehicle industry is invested in pursuing. Very similar to HD-DVD vs Blu-Ray, there was one clear winner and in our instance, the battery-powered EV won out over H2. Its sucks, but it is what it is."

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.

It's "the new generation of Tablet for simplicity and privacy..." according to its Kickstarter page. "Top-tier performance, lightweight design and completely Google-free." And it's already reached its funding goal of $53,312 — climbing to over $75,000 from 115 backers with another 26 days still to go. 9to5Linux reports: Volla, the maker of the Volla Phone smartphones, has launched a crowdfunding campaign on Kickstarter for their first tablet device, the Volla Tablet, which will also support the Ubuntu Touch mobile OS.

Featuring a 12.3-inch Quad HD display with 2650Ã--1600 pixel resolution, the Volla Tablet uses a powerful MediaTek Gaming G99 8-core processor, 12 GB RAM, and 256 GB internal storage. It also comes with a long-lasting 10,000 mAh battery, 2G/3G/4G cellular network support, Wi-Fi, Bluetooth, and a 13+5 MP main camera.

By default, Volla Tablet ships with Volla OS 13, Volla's in-house operating system based on the free Android Open Source Project (AOSP), but users will be able to buy the tablet with Ubuntu Touch featuring built-in convergence and support for Android apps with WayDroid container.
"Users will also be able to use desktop apps like Firefox or LibreOffice thanks to the help of the Libertine container," according to the article. ("Volla says that Volla Tablet with Ubuntu Touch is ideal for Linux enthusiasts and minimalists seeking a simplified, efficient, and familiar operating system experience.")

Its Kickstarter page points out the tablet even offers options like "hide.me VPN" and private speech recognition that's "cloud-independent for secure, confidential interactions."

("For U.S. users, please note that only roaming SIM cards from abroad can be used.")

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."
