Room-Temperature Superconductivity Heats Up

Room-temperature superconductivity remains a significant focus in scientific research due to its potential to eliminate energy losses in electrical systems, enhance computing speeds, and revolutionize various technologies. Recent advancements include a study from January 2024, where researchers reported achieving room-temperature superconductivity using scotch-taped cleaved pyrolytic graphite. This discovery, if validated, could provide insights into how material defects influence superconductivity. Historically, the quest for superconductivity at temperatures above absolute zero has faced numerous challenges, including issues with reproducibility and the complexity of materials. While past claims have often been met with skepticism, the current research suggests a new direction by exploring the role of defects in materials. The implications of successful room-temperature superconductivity are vast, potentially leading to more efficient power grids, advanced magnetic resonance imaging, and significant improvements in neuromorphic AI computing. However, experts caution that practical applications remain years away, as the field continues to grapple with the challenges of material production and integration into existing technologies. The ongoing exploration of new materials and techniques, including the use of generative AI, fuels optimism for future breakthroughs that could transform electronics and computing.

"(room-temp. superconductivity) would deliver nearly unlimited energy, turbocharge compute speeds, and introduce new and better ways to use computers and other electronics."

How so? It would save a few percent in transmission losses, make various quantum sensors possible/cheaper, just maybe, levitating trains, if it's cheap enough. Unlimited energy? lol.

I did a double-take when I checked the publication. I can't believe this is in the ACM journal.

> Consequently, the challenge—getting to superconductivity at temperatures above 0 degrees Kelvin (-273.15 degrees Celsius) at ambient pressure—remains a holy grail of physics and materials science.

This alone cannot be a correct statement, because the 3. Law of Thermodynamics states that you cannot reach 0 degrees Kelvin. So I think we already got some working superconductivity at room temperature by that definition.

The author clearly has not the knowledge to write over this so I stopped reading there. Also it cannot be a typo, since he even explains the corresponding degree in Celsius

Room temperature superconductors would make a lot of new things possible, like smaller and better motors, generators, RF filters, low frequency antennas, etc.

No matter how slow you needed a load to turn, you could wind a motor to do it without gear reduction.

Gear trains in large scale wind turbines are a huge maintenance issue, and failure mode. With superconducting generators, they could be converted to direct drive.

The only limits are critical temperature and critical field strength.

> Finding a way to reduce energy loss as electricity travels over transmission lines and across wires would profoundly change society. It would deliver nearly unlimited energy

Um... No. Transmission lines is not a serious use-cases of super conductors. I believe current loss rates are in the 2-5% range. Super conductors do not provide energy in and of themselves -- though they are likely a critical component to nuclear fusion, which would.
