Could Chinese team’s viral LK-99 video offer clue to superconductor holy grail for physicists?

Superconductivity at room temperature – a holy grail concept for physicists – has sparked a buzz across Chinese social media after a pair of university students from Wuhan claimed to have achieved the feat in a lab.
Their nearly four-minute video was posted online on Tuesday afternoon and racked up millions of views overnight. By Wednesday evening, it was the second most-watched video on Bilibili – China’s answer to YouTube.
The team from the Huazhong University of Science and Technology (HUST) synthesised a tiny crystal – just micrometres in diameter – under a microscope, and proceeded to demonstrate its antimagnetic, levitative properties.
This tiny dot, known as LK-99, could hold immense potential if it is a genuine room-temperature, ambient-condition superconductor as claimed by some scientists – helping to produce technological marvels such as speedy levitating vehicles and 100 per cent efficient electrical grids.

A researcher from the Institute of Physics at the Chinese Academy of Sciences (CAS) declined to comment on LK-99, telling the Post that even taking the issue seriously would be ridiculous.
His response largely represented the attitude of mainstream physicists. Unlike ordinary conductors, where electrons lose energy as they bump into atoms on the way, making the wire heat up, superconducting materials can convey an electrical current without any resistance at all.

Experts are pushing back against extraordinary claims of a room-temperature superconductor. Here's what the lab results mean and why we need time to sort things out.

When South Korean scientists in late July reported a potential breakthrough in superconductors, their claims uncorked waves of both excitement and skepticism as researchers around the world rushed to replicate the experiments.
Such a superconductor – working at room temperature and ambient pressure – is one of the holy grails of materials science, a development that dreamers suggest could maximize the efficiency of our energy grids and supercharge fusion energy production, speed up progress on quantum supercomputers or help usher in an era of superfast transport.
Right now, though, the story of the LK-99 superconductor is all about what's going on in laboratories.
On July 22, the physicists in South Korea uploaded two papers to arXiv, a repository for preprint research – the kind that has yet to be peer-reviewed and published in a scientific journal. It's basically like uploading a first draft of your work. The researchers claimed they had produced the first room-temperature superconductor with a "modified lead-apatite structure" doped with copper and dubbed LK-99.
Part of the "proof" the team provided was a video showing the compound levitating over a magnet, a key characteristic of superconducting materials.
The bold claims made a monumental splash with experts in the field.
"The chemicals are so cheap and not hard to make," said Xiaolin Wang, a material scientist at the University of Wollongong in Australia. "This is why it is like a nuclear bomb in the community."
But what happened in that lab in South Korea is just a very first step in figuring out whether the results truly have practical implications for technology and its role in our lives. We need more data, and there's reason to be cautious.

Remember this Cold Fusion research when it announced back in 1990s... It is smeared as fake research, yet fast forward 30yrs later, US army in investing $$$$$$ into Cold Fusion, are they stupid or some facts are suppressed?

After more than three decades of simmering debate in specialized physics groups and fringe research circles, the controversy over cold fusion (sometimes called low-energy nuclear reactions or LENRs) refuses to go away. On one hand, ardent supporters have lacked the consistent, reproducible results and the theoretical underpinning needed to court mainstream acceptance. On the other, vehement detractors cannot fully ignore the anomalous results that have continued to crop up, like the evidence for so-called “lattice-confinement fusion” adduced last year by a group at NASA’s Glenn Research Center.
Scientists at the Naval Surface Warfare Center, Indian Head Division have pulled together a group of Navy, Army, and National Institute of Standards and Technology (NIST) labs to try and settle the debate.
Together, the labs will conduct experiments in an effort to establish if there’s really something to the cold fusion idea, if it’s just odd chemical interactions, or if some other phenomenon entirely is taking place in these controversial experiments.

Humanity may be in the throes of another breakthrough that's every bit as impactful as the invention of the transistor and the advent (and eventual vindication) of quantum computing.
LK-99, as it's been named, is a new compound that researchers believe will enable the fabrication of room-temperature, ambient-pressure superconductors. Initially published by a Korean team last Friday, frantic work is underway throughout the research world to validate the paper's claims.
For now, two separate sources have already provided preliminary confirmations that this might actually be the real thing — Chinese researchers have even posted video proof. Strap in; this is a maglev-powered, superconducting ride.

No way Chinese scientists can achieve such discovery. Monolingual Singlish speaking Angmoh wannabe Sinkies where are you? Come out and defend your adopted race.
Levitating PMD is not a dream. But LTA will ban it.
