No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

I'm prepared to be proven wrong on this, as my exposure to quantum computer cooling systems has been super brief, but as far as I know there are no toxic coolants.
The pre cooler is a Pulse Tube Refrigerator, and the main cooler is a Dilution Refrigerator. Those both use helium, and that stuff floats out into space. I doubt it's going into the ocean. Here's another article that talks about the operation.
Like I said though, my exposure was brief. Unfortunately we didn't land any projects with the supercomputer people ๐. I'm always down to learn more about niche topics though. Makes me super fun at parties. If you have good sources shoot them my way. I couldn't find anything in my 5 ish minutes of web searching.
Wrong. I breathed in some helium once and it made my voice all high pitched which threatened my fragile masculinity. Very toxic.
(/s...)
Never worked much with cryogenics, but the one thing I learned was to never get in an elevator with (large quantities of) liquid nitrogen
if the elevator stops it can displace the oxygen and that's...kinda bad.
Yeah, totes. Scentless non-toxic gases can still be deadly by merit of not being oxygen.
The only recreational octave-shifting gas I indulge in is Sulfur Hexafluoride. Bolsters the ol' baritone.
That's no bueno for the environment.
I just looked it up and...
Umm wtf? Why are we selling this stuff in compressed air cans ? Even methane is "only" 30x more potent than CO2 .
3M made a great alternative I actually tried to get my company into, Novec 4710... But turns out they've stopped making it.
The bitch about SF6 is that it's so stable (as required, to resist high voltage electric breakdown) that it also lasts way, way long in the atmosphere.
Yeah man, I don't know. I think we need to just use less energy, as a species.
