Well not an exact advantage, but researchers have made a metal that can superconduct at -70C. (near to the lowest recorded temperature on earth.)<p>&gt;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.<p><a href="https:&#x2F;&#x2F;www.newscientist.com&#x2F;article&#x2F;dn28058-warmest-ever-superconductor-works-at-antarctic-temperatures&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.newscientist.com&#x2F;article&#x2F;dn28058-warmest-ever-su...</a><p>As the tech may improve, soon we may be able to build superconductors which will be capable of functioning on earth temperatures.
