When will the superconductive slurry be confirmed?
My guess is this weekend. It has had enough time to cook. The testing is simple - either it has negligible resistance at room temp or not.

The world is about to change very quickly if it works. Hold onto your nuggets, the ride will be bumpy!

Does it mean flying car ?

We already have electric flying cars (drones) - they are not practical but they would be with this.

Re: When will the superconductive slurry be confirmed?
idk well see

this is relevant to my field of study and the paper was so poorly written. I forgive most because they’re Korean, but it reads like an undergrads self study manuscript in physics

they also don’t really explain the actual SC mechanism.. replacing copper ions “stresses” the lead apitate? Quantum well tunneling is a huge hand-wave moment, which they don’t even really have confidence behind. would be amazing if true, but the simplistic tutorials they list in the appendix could not be reproducible from anyone outside that lab

Can you explain the last part. It is a simple formula and process they described - are you saying it is more complicated than they wrote?

yes, the intersection of physics and chemistry is a tricky field in itself. for example, in the first section, they mention ‘thin cuboids’. what are the dimensions? in which way was it cut (water jet, blade, electrons ect), as that greatly impacts the interface between measurement devices

in the same section, they pulverize the sample. to what grain size, what’s the relative atomic densities (as the replacement of Cu2+ is amorphous and only influences ‘the column’?)

in the first and third sections, a ‘reaction tube’ and ‘quartz tube’ are mentioned for roughly the same process. is the reaction tube not quartz, and if not, what material I s it?

a million little things like that start stacking up and leave much to the imagination. to be useful and ‘groundbreaking’, it is necessary to cover every little bit you can. look up the papers on yttrium/hydride SC materials. that is the amount of information you can expect. it seems yet to be peer reviewed as well

I know it seems pedantic and probably some eye rolls as people read this, but it is important to be complete, especially with claims such as this. I am hopeful for reproducibility but the paper has too many red flags to get me excited

Should have been replicated many times over by now. Should have live streams of folks doing it in their garages.

They will sit on it for months op...

Ok - thank you for that. I was also wondering what is the final size after the mortar and pestle - I would imagine that needs to be an important measurement before the baking.
I wasn't even thinking of the other variables you mentioned.

On the other hand, maybe the accuracy of the process is not integral to the effect observed with those long times in the suck oven.

If someone can replicate the results, that would have to be the case because they would have had to guess at so many things.

Or it all could be a bad cold fusion remake.

It seems like you need a fairly beefy vacuum oven for it though. Not many have one that will go down to what they stated at 1×10−5 torr. I looked on ebay and found one just under 30k.
