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.
Saw this going to a friend’s house- they bagged the fire hydrants….one thought was snow; but this is the first year apparently. And snow has been a mild issue this year compared to most.
Snow on Thursday.

Gotta ask, what kinda candy was she making? Soft crack. Hard crack. Pot….
Even has the donuts on there for, you know, dealing with the munchies.
so drop 'em if you got 'em

[question] for the chemistry types- making chicken soup. Why did lemon juice turn the light brown chicken stock almost white?
(lemmy.world)
Okay, so I was making chicken soup from stock I had made using a (lightly,) browned carcus and neck. just before dumping the the dumplings into it, the stock's color was a nice light brown. I added about 1/4 cup of lemon juice, turned my back for 30 seconds after a stir and it turned it an almost milky-off white. Eventually it deepened to this:
It's delicious, and tastes as expected, I'm just curious as to what happened in the broth's chemistry?
Seasoned with salt (duh), a sprig of thyme, some ginger and garlic, (just a hint of ginger,) black pepper, lemon zest (which was added with the torn chicken,) and white wine deglazed the pot from browning the dark meat.
The stock was from garlic, onion, celery, carrot and maybe ginger scraps cooked with the chicken carcass..
Due to reasons... I've "adopted" a CR10s that a friend had bought. It was used, and was already well on it's way to being a janky Printer of Theseus. My hope is to get it up and running and put through it's paces before the holidays so I can give it back as a gift.
With the linear rail upgrades, I picked up the hardware and it's on it's way; which got me looking at how to do the upgrade, which I have mostly figured out; the question I'm having is, most upgrades seem to place the rails on 2020 extrusions sitting on top of the base frame- same as how the original y axis 2040's were designed.
Which raises the question- why not lower it so the 2020 rails are even with the frame, with the mgn12 rail sitting on top? Like so:
The short answer I came to is this would necessitate replacing the brackets for the y stepper motor and it's idler; but it should be possible. the easiest solution would be something like:
which raises the question: are printed parts rigid enough to hold against the tension on the belts? The motors can't handle too much tension anyhow, and the printer already has the screw-cap tensioners for x and y printed that seem to have been holding up well.
has anybody replaced the OG metal bracket on the back? does it stress and need replacing often, or is it fairly reliable (and above all, consistent,)
I mean, like incompetent. For the record those organs I just stole? literally on the desk in front of him. Time to hike on over and sell it. To the Trade Authority.... all 20 feet away...
