Re: Additive manufacturing starting to get interesting

The question is whether we can economically maintain said capacity in peacetime such that we don’t have to reinvent it in wartime. That's SAAB taking advantage of a capacity existing in the civilian economy. Divergent has grown out of the automotive sector, aerospace is just an exploitation opportu...

Re: Thoughts on the Embraer C-390 Millennium tactical airlifter

How does the C-390 compare to the Airbus turbo-prop tac-lift whatsit ? They're a different class of aircraft - the A400M is a LOT bigger, think of it as the difference between narrowbody and widebody commercial jets. https://upload.wikimedia.org/wikipedia/commons/9/9b/Size_comparison_military_trans...

Re: China gets thorium molten salt reactor working

Interesting point about an MSR is that it offers a route to the permanent destruction of high-level waste. The really hot stuff can be managed by hold-up and decay, while the very long-term stuff isn't terribly risky. It's the stuff that is dangerous for a few centuries that is a real pain, and it's...

Re: Did Kyle Hill get his hands on a piecutter?

Video here: https://youtu.be/C06yW0232Bc?si=yIflx9Ni44-1MMmd It sounds a lot like how Stuart described the piecutters, though apparently this one isn’t classified. It also doesn’t do what say the nukecalculators do, which is map out damage from a specific radius. But it does sound a lot like how St...

Re: Unveiling Venice’s Hidden Secrets: The Draining and Cleaning of the Grand Canal, 1956

I'm very disappointed in that article. For something where they're talking about how influential and important Bill Perlmutter's photos were, to be only showing one of them is inexcusable. At least link to a gallery or something. That said, there's a really interesting thing on the right side of th...

Re: Aux Units in The Lion Resurgent

If there really was an O-class boat present, they would not have been messing about dropping off a half section. They would have been making bloody big holes in the landing ships.

Re: Argentina planned to ‘disappear’ hundreds of Britons on eve of Falklands War

No EW needed, the Argentinians at that point only had Roland SAMs. Stay above 20,000’ and they’re safe. Add to that all they would be facing as interceptors were Mirage III armed with -9D(? I think) so a brief escort screen would have taken care of those too. Range would probably be a bit long for ...

Knowing Ricky Philips, I’ve a pretty good sense of the validity of this. He’s an excellent researcher. It's worth keeping in mind what he's actually found though - a CIA document saying what the US government of the time was being told by it's intelligence arms, NOT an Argentinean document saying t...

Re: Corn Dollies

Not to be pedantic, but Pre-Christian Britain. . .when was this? Corn is a Central/North American grain and was introduced to Europe in the 1500s. How did the 10th-13th century Anglos, Saxons, Celts, etc make corn dollies when corn was 2 or 3 centuries in their future? Did they make their dollies w...

Re: Koenigsegg Dark Matter electric motor

The test conditions and all the details haven’t been revealed yet as Koenigsegg doesn’t want to do that until a patent process has been completed. There is absolutely no reason to do this - you won't refer to any test conditions in patent filings. So they're trying to either hype things up or hide ...

Re: Koenigsegg Dark Matter electric motor

Neat. I'm always a little puzzled by how they cool these big compact motors, even at 99% efficiency that's a fair bit of heat. It's oil flood cooling, with the oil in direct contact with all of the windings. The steady-state rating will also be a LOT lower than the transient rating: it's designed a...

No "almost" about it IMHO - matching decal on the C Pillar and rust/dirt pattern around the rear wing. I think they used this stock image without checking what type of car it was.

Re: GOP Social Media Oopsie

Lada 2101 is a license-built Fiat 124, which was more or less the replacement for the 1100 you're thinking of. I say more or less because they also made the 128, which is visually very similar to the 124.

Best equivalent image I could find of the apparent car ( 1976 Lada 2101 ) - I've flipped it to make comparison easier, so ignore the gas tank flap as that should be on the other side. image_2025-08-03_193600318.png Looks very similar but not enough identifying points to be certain it's an actual car...

Re: Elon Musk says xAI's Colossus 2 supercomputer in Memphis close to coming online

He's greatly under-appreciated. He designed and built Colossus (the world's first programmable electronic computer), largely with his own money, and more than anyone else was responsible for the reliable and timely breaking of the Lorenz
