Room-Temperature Superconductivity Achieved for the First Time

quantamagazine.org
  • A hydrogen, carbon and sulfur compound conducts electricity with perfect efficiency at room temperature, but it will never be used for things like lossless power lines.
  • It’s not practical because the compound becomes a superconductor only when crushed between two diamonds, with pressures 75% as strong as in Earth’s core.
  • But this discovery implies that it might be possible to find a superconducting compound that won’t need extreme pressures.
  • The problem is that due to the compound’s nature, researchers don’t know how its atoms are arranged, or even the exact chemical formula for it.
  • Once they figure it out, they’ll try to switch up the recipe to develop a compound that works at lower pressures.
