Superconducting wires can transport electricity without loss. This would allow for less power production, reducing both costs and greenhouse gasses. Unfortunately, extensive cooling stands in the way, because existing superconductors only lose their resistance at extremely low temperatures. In the journal Angewandte Chemie, scientist have now introduced new findings about hydrogen sulfide in the H3S form, and its deuterium analog D3S, which become superconducting at the relatively high temperatures of -77 and -107 °C, respectively.
