did xkcd just watch the new styropyro video
Apparently you saw that 400 battery video too.
I haven’t had TWO HOURS to dedicate to it just yet.
I just put that on in the background while I was cooking, cleaning etc. I actually watched the first 30 minutes like a normal video. During the rest, I was actively looking only about 10% of the time.
I usually watch these type of videos while WFH but I haven’t been able to these last few weeks.
Imagine having those explosions in the background during a meeting 😄
The slow motion video of the metal turning to vapor was mesmerizing.
A still from that video really looks like something from a space telescope. Small glowing dots and a gas cloud in the background.
“Who did the electrical work in this house?”
“That would be my nephew Thomas, he’s very handy.”
“When Thomas’s house burned down?”
“Oh about two years ago, how did you know.”
Alt-text should be “Resistance is futile”.
or “fusile”
You break ohms law. Its the death penalty for you.
I don’t know… What if he’s rich and banged some kids? Just boys being boys… /s
Good old incandescent extension cords
They’re all incandescent if you’re not a quitter.
Also everything is a fuse
Wait, I never noticed!
I can use a fuse with a safe value and still get tasty molten cheese every time I need to replace it?
mechanic: So, does it make any noises or can you smell anything burning?
customer: I can’t really hear anything, maybe a little hiss or sizzle once in a while. And nothing burning that I can smell. It actually smells really good and I’m getting hungry!
mechanic: aha! I got u fam.
From what I recall 22 rim fire shells are a perfect fit for old car glass fuses.
Eh, ~zero impedance house circuits won’t do anything bad to normal electronics - it’ll just make sure no fires happen in your walls. I do almost all home wiring in 12 gauge and larger for this reason
Actually, the comic only has 500A breakers and don’t say anything about wires. Recipe for fire!
I think that’s the joke, especially since the alt text asks about getting melted copper off the carpet.
The comic is talking about the cords that come out of the outlet into the room melting and starting fires. The guy you responded to is talking about wires in the walls starting fires.
Ah, the good old asbestos carpets. Cozy!
Yeah, I’m just imagining someone running multiple 0000 gauge (4 ought) cables in parallel to each outlet and switch, and then all back to the breaker box.
500 amps? That’s no wiring, that’s cabling.
Dude, the entire comic is about wires.
Every circuit has a circuit breaker, it’s just that sometimes the circuit breaker is the power cord or the product itself
‘Fuse’ would be more accurate.
18awg at 100A could be considered a fuse. Or a heating element. One of the two.
First one, then the other.
Check the resistance. 1,000,000,000.00 Ohms is something to pay attention to.
500 amps? Does she have a residential house or a small factory?
My main question is where can I hire a 10000 amps connection?
At your local nuclear power plant.
Sounds like something Styropyro would do.
Just another order of magnitude worse.
Somehow.
Reminder the size of breaker in the US electric code is to protect the wire and receptcle. After that you’re in someone elses hands.
Electricity is one of those subjects that will forever remain a mystery to me.

Is it a joke about EV charging in Europe? Like there are super duper chargers for super advanced car batteries and rather good coal and nuclear plants but no good network between them?
I don’t think so, also electric chargers of varying quality are super ubiquitous in Europe.
My little Eastern European hometown of 20k people has two stations of 8 plugs each.
I agree with your point, but I also assume it’s a not a supercharger-grade? Like in China they have quite often supercharger-grade in cities practically everywhere and prices per kilowatt are no different from slow-charging (like 22kW). While in Europe I noticed that price for kWh is different based on charger’s capacity.
It’s less based on the capacity, and more on how much time is likely a premium.
E.g. motorway services are more expensive, since people need the power and want to get back on the road. It’s exactly the same logic as the price of petrol there.
Makes sense! Thank you!
One of the two is actually a Tesla supercharger
Awesome! Thanks!
