Gasoline Out of Thin Air? It's a Reality!

Slashdot.org - Sun, 01/25/2026 - 16:56
Can Aircela's machine "create gasoline using little more than electricity and the air that we breathe"? Jalopnik reports... The Aircela machine works through a three-step process. It captures carbon dioxide directly from the air... The machine also traps water vapor, and uses electrolysis to break water down into hydrogen and oxygen... The oxygen is released, leaving hydrogen and carbon dioxide, the building blocks of hydrocarbons. This mixture then undergoes a process known as direct hydrogenation of carbon dioxide to methanol, as documented in scientific papers. Methanol is a useful, though dangerous, racing fuel, but the engine under your hood won't run on it, so it must be converted to gasoline. ExxonMobil has been studying the process of doing exactly that since at least the 1970s. It's another well-established process, and the final step the Aircela machine performs before dispensing it through a built-in ordinary gas pump. So while creating gasoline out of thin air sounds like something only a wizard alchemist in Dungeons & Dragons can do, each step of this process is grounded in science, and combining the steps in this manner means it can, and does, really work. Aircela does not, however, promise free gasoline for all. There are some limitations to this process. A machine the size of Aircela's produces just one gallon of gas per day... The machine can store up to 17 gallons, according to Popular Science, so if you don't drive very much, you can fill up your tank, eventually... While the Aircela website does not list a price for the machine, The Autopian reports it's targeting a price between $15,000 and $20,000, with hopes of dropping the price once mass production begins. While certainly less expensive than a traditional gas station, it's still a bit of an investment to begin producing your own fuel. If you live or work out in the middle of nowhere, however, it could be close to or less than the cost of bringing gas to you, or driving all your vehicles into a distant town to fill up. You're also not limited to buying just one machine, as the system is designed to scale up to produce as much fuel as you need. The main reason why this process isn't "something for nothing" is that it takes twice as much electrical energy to produce energy in the form of gasoline. As Aircela told The Autopian " Aircela is targeting >50% end to end power efficiency. Since there is about 37kWh of energy in a gallon of gasoline we will require about 75kWh to make it. When we power our machines with standalone, off-grid, photovoltaic panels this will correspond to less than $1.50/gallon in energy cost."

Richard Stallman Critiques AI, Connected Cars, Smartphones, and DRM

Slashdot.org - Sun, 01/25/2026 - 14:36
Richard Stallman spoke Friday at Atlanta's Georgia Institute of Technology, continuing his activism for free software while also addressing today's new technologies. Speaking about AI, Stallman warned that "nowadays, people often use the term artificial intelligence for things that aren't intelligent at all..." He makes a point of calling large language models "generators" because "They generate text and they don't understand really what that text means." (And they also make mistakes "without batting a virtual eyelash. So you can't trust anything that they generate.") Stallman says "Every time you call them AI, you are endorsing the claim that they are intelligent and they're not. So let's let's refuse to do that." "So I've come up with the term Pretend Intelligence. We could call it PI. And if we start saying this more often, we might help overcome this marketing hype campaign that wants people to trust those systems, and trust their lives and all their activities to the control of those systems and the big companies that develop and control them." "By the way, as far as I can tell, none of them is free software." When it comes to today's cars, Stallman says they contain "malicious functionalities... Cars should not be connected. They should not upload anything." (He adds that "I am hoping to find a skilled mechanic to work with me in a project to make disconnected cars.") And later Stallman calls the smartphone "an Orwellian tracking and surveillance device," saying he refuses to own one. (An advantage of free software is that it allows the removal of malicious functionalities.) Stallman spoke for about 53 minutes — but then answered questions for nearly 90 minutes longer. Here's some of the highlights...

US Congress Fails to Repeal 'Kill Switch' for Cars Mandate

Slashdot.org - Sun, 01/25/2026 - 12:34
Newsweek reports on how the U.S. Congress is debating "kill switch" technology for vehicles, "which would be able to monitor diver behavior, detect impairment such as intoxication and intervene..." "While the technology is not yet a legal requirement in cars, Congress passed a law with the Infrastructure Investment and Jobs Act in 2021 that requires the Department of Transportation to create the mandate." Republican Representative Thomas Massie of Kentucky introduced an amendment to a federal spending bill that would reverse the mandating of the technology. On Thursday, 160 Republicans voted in favor, but the legislation failed 164-268, according to the House Clerk's official roll call — with 57 Republicans joining 211 Democrats in voting against it... The House vote signals substantial Republican support for curbing any move toward mandated impaired-driving prevention systems, but not enough to pass such legislation. Critics of the kill switch technology see it as government overreach, while those in favor argue that it could prove to be lifesaving.

The Android 'NexPhone': Linux on Demand, Dual-Boots Into Windows 11 - and Transforms Into a Workstation

Linux.Slashdot.org - Sun, 01/25/2026 - 11:34
The "NexDock" (from Nex Computer) already turns your phone into a laptop workstation. Purism chose it as the docking station for their Librem 5 phones. But now Nex is offering its own smartphone "that runs Android 16, launches Debian, and dual-boots into Windows 11," according to the blog It's FOSS: Fourteen years after the first concept video was teased, the NexPhone is here, powered by a Qualcomm QCM6490, which, the keen-eyed among you will remember from the now-discontinued Fairphone 5. By 2026 standards, it's dated hardware, but Nex Computer doesn't seem to be overselling it, as they expect the NexPhone to be a secondary or backup phone, not a flagship contender. The phone includes an Adreno 643 GPU, 12GB of RAM, and 256GB of internal storage that can be expanded up to 512GB via a microSD card. In terms of software, the NexPhone boots into NexOS, a bloatware-free and minimal Android 16 system, with Debian running as an app with GPU acceleration, and Windows 11 being the dual-boot option that requires a restart to access. ["And because the default Windows interface isn't designed for a handheld screen, we built our own Mobile UI from the ground up to make Windows far easier to navigate on a phone," notes a blog post from Nex founder/CEO Emre Kosmaz]. And, before I forget, you can plug the NexPhone into a USB-C or HDMI display, add a keyboard and mouse to transform it into a desktop workstation. There's a camera plus "a comprehensive suite of sensors," according to the article, "that includes a fingerprint scanner, accelerometer, magnetometer, gyroscope, ambient light sensor, and proximity sensor.... "NexPhone is slated for a Q3 2026 release (July-September)..." Back in 2012, explains Nex founder/CEO Emre Kosmaz, "most investors weren't excited about funding new hardware. One VC even told us, 'I don't understand why anyone buys anything other than Apple'..." Over the last decade, we kept building and shipping — six generations of NexDock — helping customers turn phones into laptop-like setups (display + keyboard + trackpad). And now the industry is catching up faster than ever. With Android 16, desktop-style experiences are becoming more native and more mainstream. That momentum is exactly why NexPhone makes sense today... Thank you for being part of this journey. With your support, I hope NexPhone can help move us toward a world where phones truly replace laptops and PCs — more often, more naturally, and for more people.

The Case Against Small Modular Nuclear Reactors

Slashdot.org - Sun, 01/25/2026 - 10:34
Small modular nuclear reactors (or SMRs) are touted as "cheaper, safer, faster to build and easier to finance" than conventional nuclear reactors, reports CNN. Amazon has invested in X-Energy, and earlier this month, Meta announced a deal with Oklo, and in Michigan last month, Holtec began the long formal licensing process for two SMRs with America's Nuclear Regulatory Commission next to a nuclear plant it hopes to reactive. (And in 2024, California-based Kairos Power broke ground in Tennessee on a SMR "demo" reactor.) But "The reality, as ever, is likely to be messier and experts are sounding notes of caution..." All the arguments in favor of SMRs overlook a fundamental issue, said Edwin Lyman, director of nuclear power safety at the Union of Concerned Scientists: They are too expensive. Despite all the money swilling around the sector, "it's still not enough," he told CNN. Nuclear power cannot compete on cost with alternatives, both fossil fuels and increasingly renewable energy, he said." Some SMRs also have an issue with fuel. The more unconventional designs, those cooled by salt or gas, often require a special type of fuel called high-assay low-enriched uranium, known as HALEU (pronounced hay-loo). The amounts available are limited and the supply chain has been dominated by Russia, despite efforts to build up a domestic supply. It's a major risk, said Nick Touran [a nuclear engineer and independent consultant]. The biggest challenge nuclear has is competing with natural gas, he said, a "luxury, super expensive fuel may not be the best way." There is still stigma around nuclear waste, too. SMR companies say smaller reactors mean less nuclear waste, but 2022 research from Stanford University suggested some SMRs could actually generate more waste, in part because they are less fuel efficient... As companies race to prove SMRs can meet the hype, experts appear to be divided in their thinking. For some, SMRs are an expensive — and potentially dangerous — distraction, with timelines that stretch so far into the future they cannot be a genuine answer to soaring needs for clean power right now. Nuclear engineering/consultant Touran told CNN the small reactors are "a technological solution to a financial problem. No venture capitalists can say, like, 'oh, sure, we'll build a $30 billion plant.' But, if you're down into hundreds of millions, maybe they can do it."

The Risks of AI in Schools Outweigh the Benefits, Report Says

Slashdot.org - Sun, 01/25/2026 - 07:34
This month saw results from a yearlong global study of "potential negative risks that generative AI poses to student". The study (by the Brookings Institution's Center for Universal Education) also suggests how to prevent risks and maximize benefits: After interviews, focus groups, and consultations with over 500 students, teachers, parents, education leaders, and technologists across 50 countries, a close review of over 400 studies, and a Delphi panel, we find that at this point in its trajectory, the risks of utilizing generative AI in children's education overshadow its benefits. "At the top of Brookings' list of risks is the negative effect AI can have on children's cognitive growth," reports NPR — "how they learn new skills and perceive and solve problems." The report describes a kind of doom loop of AI dependence, where students increasingly off-load their own thinking onto the technology, leading to the kind of cognitive decline or atrophy more commonly associated with aging brains... As one student told the researchers, "It's easy. You don't need to (use) your brain." The report offers a surfeit of evidence to suggest that students who use generative AI are already seeing declines in content knowledge, critical thinking and even creativity. And this could have enormous consequences if these young people grow into adults without learning to think critically... Survey responses revealed deep concern that use of AI, particularly chatbots, "is undermining students' emotional well-being, including their ability to form relationships, recover from setbacks, and maintain mental health," the report says. One of the many problems with kids' overuse of AI is that the technology is inherently sycophantic — it has been designed to reinforce users' beliefs... Winthrop offers an example of a child interacting with a chatbot, "complaining about your parents and saying, 'They want me to wash the dishes — this is so annoying. I hate my parents.' The chatbot will likely say, 'You're right. You're misunderstood. I'm so sorry. I understand you.' Versus a friend who would say, 'Dude, I wash the dishes all the time in my house. I don't know what you're complaining about. That's normal.' That right there is the problem." AI did have some advantages, the article points out: The report says another benefit of AI is that it allows teachers to automate some tasks: "generating parent emails ... translating materials, creating worksheets, rubrics, quizzes, and lesson plans" — and more. The report cites multiple research studies that found important time-saving benefits for teachers, including one U.S. study that found that teachers who use AI save an average of nearly six hours a week and about six weeks over the course of a full school year... AI can also help make classrooms more accessible for students with a wide range of learning disabilities, including dyslexia. But "AI can massively increase existing divides" too, [warns Rebecca Winthrop, one of the report's authors and a senior fellow at Brookings]. That's because the free AI tools that are most accessible to students and schools can also be the least reliable and least factually accurate... "[T]his is the first time in ed-tech history that schools will have to pay more for more accurate information. And that really hurts schools without a lot of resources." The report calls for more research — and make several recommendations (including "holistic" learning and "AI tools that teach, not tell.") But this may be their most important recommendation. "Provide a clear vision for ethical AI use that centers human agency..." "We find that AI has the potential to benefit or hinder students, depending on how it is used."
