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. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating 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 10/19
-
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 wonder how practical it would be to recommission old nuclear aircraft carriers as cargo ships
General rule for ships, at least heavily loaded ships, is to retire after some 60 or so years. There's no exact number but it exists for each type of ship. Reason is material stress. Even though ship might look okay, they have a lot of stress when transporting cargo or in general dealing with waves. In time, these stresses cause material stress and eventually fracture.
This is the reason behind those videos on YouTube where ship splits in half in high waves. It's not that ship can't handle high waves, it's simply that ship owner wanted to squeeze more money out of the vessel and didn't want to retire it, even though he was most likely advised to do so.
They'd be in repair most of the time like right now
If it was practical they would be doing it already.
You misspelled profitable
It is far more than that.
It needs to be cost effective (which might include profotabilit6), be feasible to implement, sustainable, and a bunch of other stuff too.
Aircraft carriers and subs being the only transportationethod using nuclear is a good sign that it isn't practical for shipping. That is likely a combination of nuclear requiring highly trained staff that are not just out in the work force, the ability to procure a reactor and maintenance parts, the ability to obtain fissible material, the ability to dry dock a ship with a nuclear reactor, and a bunch of other stuff that could even be affordable without being practical for reasons beyond costs.
Profit is what's left after all that shit. My point stands lol
We don't always do the most practical thing though.
For instance lateen sails are not the best sail design but is used by every sail manufacturer currently.
Best depends on many factors beyond things like efficiency, weight, or durability. Lateen sails are easy to implement with a single mast, are easy to store and maintain, and everyone that has sailed has experience with them. Other sails might do a better job of catching the wind, but with tradeoffs on maintenance and usability.
Practicality is often complex and leans towards easier maintenance and established knowledge.
