Submission + - CATL launches 170 Wh/kg modular, heavy-duty vehicle battery w/621 mile range (interestingengineering.com)

fahrbot-bot writes: Interesting Engineering is reporting that the Chinese battery company CATL has unveiled its next-generation modular commercial vehicle battery platform, TECTRANS II, at IAA Transportation 2026 in Hanover.

Rather than a basic cell update, the system is a adaptable modular architecture that integrates into existing vehicle lines. Truck manufacturers can achieve up to 1,000 kilometers (621 miles) of range on a single charge, backed by megawatt-level fast charging that replenishes 80% capacity in 25 minutes.

The battery delivers a gravimetric energy density of 170 Wh/kg, exceeding the industry average by 13% and increasing payload capacity by 0.6 tonnes.

CATL rates the heavy-duty truck setup for a 12-year, 1.5-million-kilometer (932,056 mile) operating lifecycle while retaining 70 percent capacity.

At present, no. I've done a number of experiments with LLMs' capabilities with generating fiction, and while they are impressive for a beginner writer -- because fo the lack of spelling and grammar mistakes, they are nowhere near being able to write competent fiction.

This is because they don't model reader or character minds, they're based on word probabilities, like a predictive text keyboard. The engineers can compensate for for this to a surprising degree by feeding it data to recognize specific situations (e.g. the car wash is 100 feet from my driveway; should I drive or walk?). But this is turd-polishing.

Comment If you're educating students for an "AI Era" (Score 4, Insightful) 119

AI technology practice isn't foundational. Critical thinking is. The closer AIs come to being able to do something that looks like them doing our thinking for us, the more capable we have to be at thinking without them. A human who can't outthink an AI adds nothing to an AI-human partnership.

This proposed school is a typical scheme by people who think because they have been educated, they understand how the education works. This is like thinking because you eat, you know how to cook. Project work in education is nothing new; it goes back well over a century. And in real life, you may get a STEM degree, but your real education in engineering comes from real life work. But that doesn't mean classes in calculus and physics don't do anything for you.

Or English classes, for that matter. Nobody doubts the value of project work in education, particularly *androgogy* -- the education of adults. But for *pedagogy* you have to establish foundational skills as the student matures intellectually and socially. Entering the high school years, a typical student has had *no* training in critical thinking skills. To develop critical thinking skills in an area, you need both general skills (epistemologicla literacy: research, location of orignial sources, dealing with conflicting evidence) and domain specific training in that area. In other words, *liberal arts* training is foundational in an AI-saturated world. "Liberal Arts" -- from *artes liberales*: literally the skills necessary to be a free person.

But I think these people have at least got the problem right: as AI drives the cost of elaborate projects down, we all have more projects in our future. Big, elaborate, faultlessly plausible-looking projects which may or may not have actual value.

Where they are completely wrong is the solution, which is to organize education around practicing using AI to make impressive projects. In a word of AI-enamored dunces this will put you at the head of a very sorry class of ignoramuses. The answer is to build fundamental cognitive and intellectual skils at every stage of a student's development. Project work is surely part of that, but it's just a technique, not a solution.

In a nutshell, the academy is training students to be the next step down the evolutionary scale from code monkeys. More like the pigeons B.F. Skinner trained in WW2 to peck at a screen, in an attempt to create a primitive guided missile without computers. They want to create "main characters"; and they'll probably create a few. There are always a few natural autodidacts in any moderately large group. But what they are set up is to produce a bunch of fragile, economically privileged narcissists trained to cover their lack of education with impressive-looking AI slop.

Submission + - New tin-based solar cells trap heat 1,000 times longer, could beat 33% limit. (interestingengineering.com)

fahrbot-bot writes: Interesting Engineering is reporting that researchers at the University of Groningen in the Netherlands found that tin-based perovskite solar cells can slow heat loss from high-energy “hot electrons” by a factor of 1,000 and could push solar cell efficiency beyond the theoretical 33 percent limit.

When sunlight strikes a panel, photons jump-start electrons into action. The most energetic photons create super-charged hot electrons. Theoretically, these high-voltage powerhouses should generate far more electricity, but, in practice, they are fleeting. In fractions of a trillionth of a second, these high-energy particles rapidly cool, dumping their bonus energy as waste heat before ever leaving the solar cell.

“This means that the energy is lost before the hot electron exits the solar cell material,” said Jan Anton Koster, Professor of Physics of Novel Semiconductors and Devices at the University of Groningen.

Using a specialized solar cell material called tin-based perovskite, Loi’s lab performed a feat many thought impossible: she slowed the heat loss down by a factor of 1,000. Suddenly, the extra energy lingered for nanoseconds instead of vanishing in picoseconds.

The study findings were published in the journal ACS Energy Letters.

Submission + - Google fined more than €400m by Irish regulator over its use of location da (theguardian.com)

AmiMoJo writes: Google has been fined more than €400m (£345m) over the way it processed users’ location data, following claims that the tech giant had manipulated users into agreeing to be constantly tracked on their mobile phones. The fine, imposed by Ireland’s Data Protection Commission (DPC), comes after complaints from multiple European consumer organisations that Google was following every step users took.

The DPC launched its inquiry six years ago and set out to find out whether Google had a valid legal basis for its use of location data. It found that Google users could have been unaware that their location was being used to influence them with adverts or to gather details about their health and interests.

Submission + - Public inquiry 'clouded Letby's innocence'

Mirnotoriety writes: Letby’s lawyer: Public inquiry ‘clouded by her innocence’

The findings of the Thirlwall Inquiry will be clouded by Lucy Letby's innocence, her barrister has said.

On Tuesday, Lady Justice Thirlwall will publish the long-awaited report into how the NHS and other institutions could have prevented Letby from killing seven babies and attempting to murder seven more at the Countess of Chester Hospital in 2015 and 2016.

But large numbers of medical and legal experts have questioned Letby's guilt and the Criminal Cases Review Commission (CCRC) is deciding whether to send her case back to the Court of Appeal.

At the outset of the inquiry in 2024, Lady Justice Thirlwall emphasised that the inquiry's remit was not to retry the case or review Letby's guilt.

She refused Mr McDonald's request for Letby to be represented in the £18m hearing ..

Submission + - Lawsuit challenges intimidation of DHS observers across the country (npr.org)

joshuark writes: NPR reports that a new lawsuit follows a handful of other cases brought by observers arguing First Amendment violations, but it is the most sweeping to date, as it includes incidents from multiple states and seeks national relief. It is asking a judge in Washington, D.C. to bar federal agencies from intimidating or retaliating against observers.

"The right of citizens to criticize and hold our government accountable is the backbone of American democracy – and it is under attack," Common Cause's vice president for litigation, Maryam Jazini Dorcheh, told NPR. "We want to make sure we're promoting participation in the political process. And obviously, if government officials are criminalizing peaceful observation, that hinders our mission," Jazini Dorcheh said.

The lawsuit describes disturbing encounters seven Common Cause members had with federal officers in Maryland, Minnesota and New Jersey after trying to observe immigration enforcement. They include being photographed, followed, reported to police, pepper-sprayed or threatened with a visit to their home by federal officers. Federal officers did show up at one Common Cause member's Minnesota home.

NPR did not receive an immediate response from DHS or DOJ about the lawsuit's allegations. The FBI declined to comment.

While the energy source of wind and solar are free, building and maintaining the plants is not free.

If all they were building were a single 100MW data center, sure: renewables would be cheaper to build. But they evidently are planning a major campus that will consume most of the plant's 615 MW output over the next 25 years.

A solar installation, in a favorable location, capable of supplying 600MW around the clock (with battery backup) would have to be roughly 1800MW in capacity. It would be among the largest inthe world, on the order of ten thousand acres in size at a build cost of maybe 2 billion. The battery backup system to ensure 99.9% uptime would be 9x the size of the largest li-ion grid storage system ever built, and set you back on the order of 4-5 billion dollars.

While it's probably cheaper to go renewable than build a *new* nuclear plant, if you can reactivate and one for just two billion that looks like a bargain, if you have a use for all that power. Inability to save money by load following is the financial Achilles' heel of this generation of reactors, but if you have a guaranteed customer for most of your output, years in advance, that's as close to an ideal economic case for them as anything could be.

ToS is the strongest argument, but the distillers are not parties to the ToS. They get their data from data brokers. It is possible that data brokers are violating the ToS, but it would be hard to write ToS that precluded running queries for third parties without creating problems for consultancies and other businesses. Even presuming the ToS could be written to preclude the data brokers doing that, it doesn't affect the resulting model.

But the general shape of the argument brings us right back to unclean hands: we worked hard on this model and it's not fair for you to profit off our work in a way that doesn't have our permission.

I think the fair-minded position is to see what people think when the documentary comes out. You're essentially arguing a negative here -- that there *can't* be anything of value that hasn't been said yet.

Also, I don't think saying something *new* is necessarily critical. Sometimes saying something obvious but in an interesting way is worthwhile.

In this case, Holmes gave access to the filmmaker. Obviously she has an agenda. If the filmmaker is smart, he has an agenda that's different from hers. If he knows his business he'll find something interesting to show you from that conflict.

Now looking at the trailer -- holy shit that woman gives off batshit crazy vibes. That's new to me. I expected her to be slick, persuasive, like Saruman in Lord of the Rings: someone. you'd need real strength of mind to resist being persuaded by. If I'd just handed someone like that my business card, I'd get it back on some pretext then head as fast as I could for the door.

It doesn't make it *right*, but it does make claiming it is *wrong* inconsistent with their own behavior. This could prevent the US companies from suing the Chinese companies seeking an injunction (due to the "unclean hands" doctrine), and probably blocks them from seeking monetary damages in most US jurisdictions.

And suing may undermine the US companies own intellectual property claims by exposing their shaky foundations. An AI model isn't *expression*, so it can't be copyrighted. Insofar as the service allows the underlying model to be deduced through regular usage, trade secret protections don't apply because that's *reverse engineering*, which trade secrets don't prevent.

This leaves violations of terms of service. But setting aside the dubious enforceability of anti-reverse engineering provisions, the Chinese companies may not even be parties to the ToS agreement if they are obtaining the model data through a network of contractors and shell companies.With only moderate paranoia, they can effectively shield themselves from some kind of US tort claim.

Which leaves them with the model they've created from the US company's model, but which the US company has no IP claim upon. If I download a DeepSeek model that's been (hypothetically speaking) trained on Claude, Anthropic might not like that, but what can they do about it?

It's a strange situation. US investors are spending cumulatively on over half a trillion dollars a year in the hope of owning a breakthrough frontier model that is the end of the economic world as we know it. But the essence of the model might not be intellectual property at all.
