World News
A community for discussing events around the World
Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF OCTOBER 19 2025
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

I can cook 230C low steam, 130C medium steam, 100C high steam in my oven
At 230C without a sealed pressure vessel there’s no way the temperature probe is still functioning as a wet bulb thermometer. That temperature in your oven is going to be dry bulb.
A wet bulb thermometer measures the temperature with the probe completely immersed in liquid water. At 230C there won’t be any liquid water at anywhere near atmospheric pressure. 230C corresponds to a saturated steam pressure of 27 bar or 2.7MPa (391 PSI). That’s nearly 10 times the pressure in a pressure cooker at max temperature.
Well it's EOB9S31WX I believe it's pressure sealed because if I make fries and leave water steam is only going out when I open oven. The manual is here https://media.flixcar.com/webp/synd-asset/Electrolux-271175672-8ffb5481-853f-4c96-978a-e9d79845e09d.pdf page 16 if you're interested.
Just for further reference, 27 bar of pressure is equivalent to 268 meters depth under the ocean. There’s no way a home oven can be built to contain that amount of pressure.
You may set your oven to 230C and put a dish of water in there, but if you placed a wireless temperature probe in the water the temperature would be at or below 100C until the water boiled away and the probe was exposed directly to air and steam. No matter how hard you tried you could not get a reading much above 100C with the probe immersed in liquid water.
Looks like those ovens have steam pump and drain pump. Interesting, how big would be device that would sustain 27 bar pressure ?
Depends on the capacity, but in general it would have really heavy reinforced walls, like a really high pressure boiler.
I have an instant pot and an espresso machine. The instant pot can manage maybe 2 bar, the espresso machine up to 4 (in its boiler). Both are pretty heavy construction.
I figured out so far that Locomotive engine have 200-250 psi that is 13-17 bar. Maximum implemented boiler pressure so far is around 350 psi 24 bar. So it probably would be a world record machine. :)
Yes I think we’re approaching the territory of submarines that can visit the bottom of the ocean!
