Comment It's not a spy, but shoot it in the back anyway... (Score 0) 79

Yup, very American. Wait until they know it's unarmed, that it's leaving, and then shoot it in the back.

FWIW It's most likely a Chinese version of Google's "Project Loon" that got away, and is very similar to a device found floating over Japan a few years back.

JP Aerospace know a thing or to about the technology (and hold the airship altitude record) so well worth seeing what JP reckons https://www.youtube.com/watch?...

But why tell everyone otherwise? Politics I guess.

Submission + - SPAM: Oak Ridge National Laboratory Joins The Patent Troll Ranks

vik writes: Composed of a nozzle suspended from a series of cords controlled by cable winders, the SkyBAAM system is designed to serve as an alternative to gantry-mounted concrete 3D printers. However, ORNL’s successful patenting of the technology has drawn the ire of RepRap Project creator Dr. Adrian Bowyer, and Dr. Joshua Pearce, who highlight its similarity with the now-eight-year-old ceiling-mounted Hangprinter.

The original creator, Torbjørn Ludvigsen, is crowd-funding a defence against the patent at [spam URL stripped]...

"The patent should never have been awarded," says Pearce. "If you read the patent, the problem they were trying to solve, was how to get rid of the gantry systems for large building-style 3D printing. They did this by copying the open-source Hangprinter concept, only scaling it up and using concrete instead of plastic."

Comment More Just-In-Time, just what we need. Ummm... (Score 1) 51

It's interesting that after the collapse of the Just In Time warehousing under Covid, and the bollox-up of Suez Crisis 2 that is yet to hit, Boston Dynamics decides to launch a robot to help cut Just In Time margins even thinner.

That strategy only works in a stable world, and I don't think we've got one anymore.

Comment Unwanted intermediate concept (Score 2) 112

There seems to be marked reluctance to stop using fossil fuel for air transport. It requires a shift in attitude: High speed long distance travel is out; it's beyond our carbon budget. Much like Concorde.

The obvious solution to long distance air travel is to use airships. We're waaay past Hindenberg-era technology. They'll cross the Atlantic on the fuel needed to get an A380 to from the departure gate to the runway at Heathrow. They can run on biofuel, batteries, solar, whatever. They're limited by weight, not volume, which means plenty of cabin space for R&R on the inevitably longer flight. Sure it takes longer, but when the alternatives are not flying or scorching the planet people might come round to the concept of a more leisurely, comfortable flight.

(This is very similar to the "we need natural gas power stations as a temporary measure" gambit. The gas plants are obsolete already, and only hold up the installation of carbon-neutral plant.)

Comment Elephants in the room: Steel and cement (Score 2) 301

Huge amounts of coal are used in Germany for making steel and cement. Not entirely sure how much - hard to google the numbers - but the steel companies in particular aren't going to like it. They rely on cheap electrical power to run arc furnaces as well as using roughly a quarter of the coal directly.

Absolutely agree. Going to China made me realise how dependent we'd become on a very few communications service providers, all of which have government hooks deeply embedded. Worse, the West has an open season on corporate information gathering and trading schemes using said services.

In China, I used WeChat because it is used for every damn thing over there. However, on my return I became very keen on promoting Open Whisper Systems' Signal, using DuckDuckGo.com instead of Google, abandoning Facebook except for communication with uneducated family members, and not physically taking my data through borders in any recognisable form.

Comment Open Source car firmware pls (Score 1) 160

Forget the infotainment/bugging crap - we have that already and it's called a smartphone. What we need is Open Source and Open Standard systems for controlling the car and - new kid on the block - battery management.

Real hardware and software already exist in projects like Tumanako which even have the foresight to integrate with distributed power generation systems. But no, big auto manufacturers still focusing on bling that will date faster than a Miley Cyrus video.
