Researchers in Germany have confirmed that hydrogen sulphide – the compound that gives rotten eggs and farts their distinctive odour – can conduct electricity without resistance at a record-breaking –70 °C. Smashing the previous record of around –110 °C, the research draws us ever-closer to the dream of a room-temperature superconductor that could one day change everything about how we generate and transmit energy.
