Superconductors transport electricity without loss or resistance. So far, however, they have only worked under extremely cold temperatures (from around -200 degrees Celsius). Now, for the first time, researchers have developed a superconductor that can conduct electricity without loss at room temperature.
They created a sulfur hydride with high proportions of hydrogen from hydrogen, sulfur and carbon and converted the material into a superconductor under extremely high pressure with the help of a so-called diamond die cell. At 267 gigapascals - that is 2,5 million times the atmospheric pressure - the electrical resistance in the sample sank to zero. This set a new record.
The high pressure that is required is still an obstacle to mass production. However, the scientists are confident that they can achieve the properties of room temperature superconductivity at lower pressure by “chemical tuning” the three-part system.
If the innovation can prevail, loss-free power lines are conceivable, which could also be a breakthrough for very fast magnetic levitation trains, more powerful magnetic resonance tomographs or innovative quantum computers.
