GM strongly pushes paying for its OnStar data plan

I think this is a line I would draw legally, much like every car has to include an ODB2 port if it's equipped with a cellular modem it must include a SIM slot or a user programmable eSIM. No technical excuse otherwise on that one, that's pure lockin for money.

Comment Re:It's just not correct (Score 1) 24

Actually, I expect that parts of the TSMC assembly factories are automated, which would make them "AI factories". A computer center is not an "AI Factory" unless it is running a factory.

Another plausible meaning would be an organization that turns out AIs, like OpenAI or Anthropic.

Most other uses are abuse of the language.

I don't think "most likely" is a suitable basis for safety rules. OTOH, one also shouldn't demand certainty, as that's not going to be possible. Say a solution that would work in over 97% of the cases...perhaps even a bit more conservative.

OTOH, nothing will protect you against an ID10T error.

every time it's been tried there's been show-stopper corrosion which they thought they had solved in their design already.

Understood but I think you should keep in mind that Molten-salt batteries have become a thing.

That doesn't guarantee that it will happen again, but...

If you never try then you can never succeed. Science is full of repeated failures... and then someone gets it right.

China is going to prove it before Bill Gates does

This is partly (or mostly I would say) due to the fact that in China the state owns both of it's primary nuclear power construction and operation companies. Those things like standard designs, quality standards are more controlled since the project goal can be to build the plant and just stay on budget, not necessarily turn a "profit" or have to go seek investment.

If and when China wants to build their own sodium fast reactor (they may already be) they'll declare it a project, fund it and just start doing it.

Comment Sodium-cooled fast reactor* (Score 4, Informative) 51

Natrium is an older term for sodium, a chemical element with the symbol Na

So really, this is a sodium-cooled fast reactor which means they are using molten salt for thermal energy storage. If I understand correctly, development has been held back material science problems since sodium is chemically reactive.

Why sodium? The benefit of sodium is that you reduce the risk of a meltdown since water has a relatively low boiling point. This allows the reactor to be "hot" run which is called a "fast reactor" Water-based fast reactors have to be run under high pressure so there is more risk involved.

Why makes fast reactors desirable? Per Wikipedia:

All fast reactors have several advantages over the current fleet of water based reactors in that the waste streams are significantly reduced. Crucially, when a reactor runs on fast neutrons, the plutonium isotopes are far more likely to fission upon absorbing a neutron. Thus, fast neutrons have a smaller chance of being captured by the uranium and plutonium, but when they are captured, have a much bigger chance of causing a fission. This means that the inventory of transuranic waste is non existent from fast reactors.

My job was always to get 'er done, cheaply as possible with every quality and standard met, and now I see that coming with just renewables and storage...cheaper

It depends on how far "net zero" you want to go. There are still a lot of people who live in places where the sun doesn't shine much for a good chunk of the year. It also gets dangerously cold. Heating a home uses an enormous amount of electricity. If you still plan on supplementing with natural gas, it's less of a problem. If you want to go all-electric, you are going to have to figure out how to generate a lot of power when the wind doesn't blow and the sun doesn't come out much so people don't freeze to death.

Comment Re:No, publicly traded corporations are. (Score 1) 49

You keep harping on "publicly traded" as if a privately-owned corporation is any different.

Yes, because they are different. Privately-owned corporations may be better or worse but it's entirely dependent on the goals of the leadership. With publicly-traded corporations, the goals are already known: profit over everything else.

The focus on profit as the primary concern is the same.

No, it's not the same because not all executives in privately-owned corporations don't have to worry about a quarterly earnings report could oust them from their position. Some privately-owned corporations mirror the behavior of publicly-traded corporations but not all.

I don't disagree with your premise, just the odd repetition of the qualifier.

The difference between them seems subtle but the impact is not because being publicly-traded guarantees they will be 100% profit driven. To my knowledge there is no exception to publicly-traded companies being entirely profit driven but I do know of examples of privately-owned corporations that are not.

Weapons detections systems send automated alerts. The specific form depends on the system. But no system is dialing up unanticipating randos on the phone and going, "Hello, police? I've got an emergency here!"

And unless the system had facial ID, and the police knew the "suspect", what they had to go on was the picture from the security camera, so they were already looking at the supposed "gun" in the picture and still saw fit to act like this.

Was a study done showing putting out cones and road flares is effective at alerting motorists that there is a disabled truck?

I honestly don't know if there was or not. However, if there wasn't (and a fair number of regulations aren't based on studies, nor are particularly well thought-out) why would a study need to be done to modify an existing regulation?
