Technology

I would suggest not posting research papers as news, especially regarding superconductors which was controversial topic last year. I found a Chinese article that references this tweet, which I assume is where you got your post from:

The paper's title uses "Possible Meissner effect near room temperature", which does not automatically translate into the sensationalist title "room-temperature superconductor".

Some of the authors of this paper have responded to questions on Zhihu (something like Chinese Quora) here: https://www.zhihu.com/question/637763289 https://www.zhihu.com/question/637763424

From what I gathered this paper is a milestone on the road to a "near room temperature superconductor", and there is optimism but more work needs to be done.

The nice thing about this, if it's true, obviously, isn't even so much about the SC they found but the possibiliy of a true room temperature SC with a similar chemical makeup. It would be quite nice if we can have a good SC for power transmission, or anything else really, by the end of the year.

I wonder how this could change the world.

even though it isn't exactly room temperature, 250K is warm enough to be chilled by dry ice, which is not that hard to come by. if this is true this is a huge breakthrough that will change the world forever. please, god, let it be true.

Hopefully it isn't like the Korean one.

But it's coming out of China and china made a load of fake papers about making lk99 to be a superconductor at room temp so I'm not holding my breath.

I've worked in places with walk in freezers before, that's technically a room.

Technology is my dump stat, what does this mean?

see a lot of people here talking about how its not really high temperature or being skeptical, but i would just like to point out that it doesnt matter, ceramic type superconductors with similar properties have been known about for decades and nothing has ever been done with them because they just arent useful for the things that metallic super conductors are used for, u cant make a cable out of this stuff and even if u could it would be too brittle to use, in the one picture of lk-99 that gets circulated everywhere u know their big media showcase picture they couldnt even make a full puck of it its that fucking brittle. IF this is true then it still is an interesting discovery that could lead to something but this is by no means the big super conductor breakthru that so many people are presenting it as, this aint the holy grail the holy grail would be this but metallic.
