I feel like it’s weird to talk about kids learning hygiene or bathing or grooming at work is weird.

But super important to actually teach your kid- and id put this in that category.

and bacon scraps!

Calling teslas “Swasticars” and CT’s “”Wankpanzers” was supposed to be a joke.

“Everybody does it….”

Are they really scientists? Or are they anti-science quacks who can’t even look at a chart and recognize the numbers are changing?

or rather, a half a one.

Watching planes doesn’t have to be a Disney experience with a soundtrack.

better than a "close encounters of a third kind" experience. Just saying. ;)

What you might deal with is heat soak if the fans can’t move enough air over the condenser core. But modern vehicles are immensely more efficient than even 10 year old vehicles.

You're point?

They're not designed to idle for extended periods, and doing so puts strain on the systems. that the cars are "more efficient" doesn't change that.

the AC compressor isn't a significant load, no. But it' expects a certain engine RPM coming into it, and it's designed at that. It's significantly less when the engine is idling because that's below it's designed range. There's a reason the manufacturers tell you not to idle your car for extended periods (mine says more than 10 minutes, my last one said 5.) and this is part of it.

the increase in RPM modern cars do isn't for the AC system. it's to keep the engine from stalling and running smoothly... the compressor is still not designed to operate at that RPM.

However, disagree with the statement that a climate control system is not meant to be operated while idle. That is an old myth that I expect came from back when there was fewer electrical components in the car so not turning the ac /off/ before turning the vehicle off would risk damaging the cars electrical.

that's not actually a myth. The car is functionally not designed to be left on idle for extended periods. (Note, I'm saying extended periods. Warming/cooling your car at idle is normal. idling at a stop light is normal. Five minutes while waiting to pick some one up is normal. Leaving it to stay cool for 2 hours is outside that design window.)

When an engine is idling, it's turning at a lower RPM than when moving. of particular note here is that the alternator and AC compressor are both driven by the serpetine belt directly connected to the crankshaft. The lower RPM makes both less efficient. For the compressor, what this means is that the AC system is turning more slowly than it normally would, reducing the total amount of cooling. For the alternator; it produces less electricity and may cause the battery to be discharging. Depends on some things, including how hard the AC is having to work, etc.

Further, because the car is not moving, there is less air moving around the engine compartment (or wherever the radiator for the engine and the AC is located.) This equates to higher operating temperatures for the engine, as well as yet more reduced ability for the AC system to remove excess heat from the cabin.

just because an AC can be run at idle for extended periods doesn't mean it's designed to, and doing so, especially on old or poorly maintained systems, in excessive heat, is likely to cause it to crap out where it wouldn't have normally. Is it a particularly high probability? Not really. Is it still too high considering it's a life-safety system? fucking absolutely.

one of the kids was 2. she had a kid at 18.

Still not an excuse. I knew I wasn't supposed to be left in a car alone at five. I knew that because I wanted to stay in the car and mom wouldn't let me. I'll have to apologize for the tantrum I probably threw.

wait... the staff KNEW?

Fuck them too.

I mean, it could be interesting if they piped in ambient noise from outside the boarding area, etc, into the boarding area, particularly around the windows where you can see your plane and stuff.

Or like if there's an observation lounge watching take offs and things.

I assume that's not what they're talking about because no way an airport could be that cool, but details.

Darth Jar Jar would be furious to know they covered up his image.

hessa gonna doossa summa sithy shitty.

And that assumes the AC didn’t crap out earlier because it was left idling in ridiculous heat. The system is not designed to be idled that long, and the cooling systems assume the car is moving for most of the time it’s on. (Both the engine and the cabin ac here.)

Even if the car didn’t turn off automatically, it’s still dangerous and in the “extremely stupid” degrees of negligence.

….why? Was it just the display shoe or something?

And anakin blamed the younglings.

Lol. Ancient Atlantean Curse: May you have the dystopia you create.

Maybe if the spoon is ferromagnetic?

“Dammit Seven, when I said ‘I could use a good probe up my ass’, that’s not what I had in mind!”

Even with the context, the fact that Grok even engaged with the prompt is bad.

At the best it shows that the Ilm is lacking in guardrails to keep it from spouting Nazis shit. The joking retort about “gigajew” also probably shows it was trained on some horrifically offensive material. (Probably Elon’s tweets and DMs)
