Well not an exact advantage, but researchers have made a metal that can superconduct at -70C. (near to the lowest recorded temperature on earth.) >The researchers found that under the pressure from their diamond anvil it transformed into a material that superconducted at temperatures as high as -70 °C, breaking the previous record of around -110 °C. https://www.newscientist.com/article/dn28058-warmest-ever-superconductor-works-at-antarctic-temperatures/ https://www.newscientist.com/article/dn28058-warmest-ever-su... As the tech may improve, soon we may be able to build superconductors which will be capable of functioning on earth temperatures.
