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.

That sounds like "pie in the sky":
The problem with fusion reactors is exactly the containment of the plasma and avoiding that it dissipates its heat through light emission.
If that was solved we would be better off doing fusion with plasma rather than fission, since even deuterium (a heavier form of hydrogen atoms because it has 1 neutron in the nucleous) can simply be extracted from the water and the H+H fusion reaction releases more energy than any fission reactions (and, funilly enough, would produce the much rarer helium, that's needed for those reactors of yours).
That's one problem. Neutron embrittlement is another.
Yeah, I was just addressing the previous post.
In all fairness I only checked what's going on with fusion once in a while as my background is Physics (as in, I started a degree in it and then ended up going to EE because in my home country there really only are jobs for theoretical physicists, not the more hands-on kind) and hence only know it at a superficial level (of somebody with the background to understand Particle Physics but not a domain expert).
Yeah, I do know about the embrittlement of the container walls due to neutron emission from the fusion reaction (no idea how bad or not that is compared to the rest), but last I checked plasma containment was still a bit of a problem as was the plasma cooling through photon emission (mind you, that might not be as much of a problem for the kind of temperature of the plasma the previous poster was mentioning, which - I assume - are less that what's need to induce fusion).
That said, all in all it just sounds strange to use fission to generate a plasma - I mean, bloody fire generates a plasma (the flame is a plasma) - so I don't quite see the point of generating plasma with the whole overhead of a nuclear reaction rather than, say, high powered lasers, high-voltage currents (yeah, lighting is plasma) or just plain old chemical reactions.
That whole thing sounded a bit too much like "fancy sciency words thrown around to deceive the ignorant" so common in scams.
