Hmm, a room temperature superconductor

Not bad , but it only works at very high pressures.

An A for effort ,but could do better

In case you're wondering ,it's a " carbonaceous sulphur hydride compound"

Nowhere near. In fact completely pointless.

It is at least possible to cool conductors in some circumstances so that superconductivity can be achieved. CERN relies on superconducting electromagnets, if I'm not mistaken. But these absurd pressures are quite impractical.

And the suggestion that this somehow opens the door to the same thing at lower pressures doesn't seem to stand up. It looks to me like an obscure curiosity and that the researchers are hyping it in the hope of further grant money.

So you discount the researchers expectation that "The introduction of chemical tuning within our ternary system could enable the preservation of the properties of room-temperature superconductivity at lower pressures." What is your reasoning?

I discount it because I do not find that statement at all persuasive. The abstract makes no mention of evidence of any "tuning" that has shown promise in this respect, nor of any theoretical reason why it might be a reasonable expectation. And the gap to be bridged in pressure is enormous. The pressures they are using are of the same order as those needed to produce a metallic phase of hydrogen.

technique is the same but can be further developed with carbon to create graphine which would be stable even in room temperature. but before it is created lot of pressure is going to be needed to make that.

No surprise really , the higher the temperature , the greater the outward pressure , from the source .

In the Cold , minus 400 Kelvin , the closer physically things can get , no pressure needed . Hence the superconductivity without friction of any kind .
