Obvious right or left wing sources will be removed at the mods discretion. We have an actively updated blocklist, which you can see here: https://lemmy.world/post/2246130 if you feel like any website is missing, contact the mods. Supporting links can be added in comments or posted seperately but not to the post body.


3. No bots, spam or self-promotion.


Only approved bots, which follow the guidelines for bots set by the instance, are allowed.


4. Post titles should be the same as the article used as source.


Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.


5. Only recent news is allowed.


Posts must be news from the most recent 30 days.


6. All posts must be news articles.


No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.


7. No duplicate posts.


If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.


8. Misinformation is prohibited.


Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.


9. No link shorteners.


The auto mod will contact you if a link shortener is detected, please delete your post if they are right.


10. Don't copy entire article in your post body


For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

Insane capacity batteries

Lossless power transmission via wires

Better magnetically levitating trains

Much more power efficient computers, electronics

The list is huge

The only drawback is that LK-99 is polycristalline... Levitating trains and computers, electronics, are a stretch as long as the material is not monocristalline.

It is huge nethertheless.

ELI5 :

Think of the material as a powder. You can compress the powder and make current flows though it. It's good for wiring, etc.

But to have an application in electronics, it would have to be like a metal, which it can't be since it's a powder

Metals are usually polycrystalline. Not sure what you're trying to say.

no i know many of the applications, its huge if true! i understand that, but almost everything like this comes with trade-offs, and i was wondering if there are any here that would make it non-viable for some/all applications

The claimed saturation current is very low. If this is inherent and not just a first-try thing it will be less-good than permanent magnets for doing many magnetic-field things and less-good than Aluminum for some current-carrying things.

It's a perovskite, in semiconductor applications these have stability and durability problems.

It might also be a scam. This would make it useless.

Power cables are currently (heh) designed to operate below 90degC, because after this you get thermal runaway and the conductor melts. That's already within the operating range of this.

[–] [email protected] 3 points 1 year ago

from what i read, it doesn’t seem like you’re able to push much current through it, which makes power cables an unlikely application in its current (heh) form
