Superconductors are materials that allow electrical current to flow with no resistance, a property that would revolutionize power grids where energy is lost in transmission as well as advance fields such as computing chips, where electrical resistance acts as a speed limit.

I’ve heard claims like this before.

The hallmark of science is replicability. I.e., can two independent teams of researchers, using similar means, methods, and materials in completely different settings, replicate the findings of the original team?

So…

Researchers from at least three Chinese universities have in recent days said they produced versions of LK-99 with varying results. One team from the Huazhong University of Science and Technology posted a video purporting to show the material levitating over a magnet, which is important because true superconductors can float over a magnet in any orientation, without spinning like a compass.

But…

…another team, from Qufu Normal University, said they did not observe zero resistance, one of required characteristics of a superconductor. A third, from the Southeast University in the eastern Chinese city of Nanjing, said they measured zero resistance, but only at a temperature of 110 Kelvin (-163 degree Celsius).

And…

The possible bad news for LK-99 is that the superconducting field is full of materials that hold promise at first but fall apart under scrutiny. Researchers even have a handy name for them — unidentified superconducting objects.

A.k.a “USOs.” As the linked article points out, plenty of smart, hardworking researchers have claimed to have found a “superconductor,” but then their claims simply fall apart under scrutiny.

Be careful of finding what you seek.
