Over the last few months, media headlines hailed a potential breakthrough in the energy crisis with claims from South Korean scientists Sukbae Lee and Ji-Hoon Kim of creating a room-temperature superconductor, named LK-99. The material, a greyish-black phosphate mineral, purportedly exhibited superconductivity without the need for extreme low-temperatures, currently achieved by helium. However, scepticism has arisen within the scientific community, with experts questioning the validity of the findings. Efforts to reproduce the results have so far been unsuccessful, and some speculate that the observed effects may be attributed to impurities in the material. Despite the uncertainty surrounding LK-99, the pursuit of a practical room-temperature superconductor with transformative applications continues. As of now, helium is crucial for creating superconductors.
