The first room-temperature superconductor has finally been found

It’s here: Scientists have reported the discovery of the first room-temperature superconductor, after more than a century of waiting.

The discovery evokes daydreams of futuristic technologies that could reshape electronics and transportation. Superconductors transmit electricity without resistance, allowing current to flow without any energy loss. But all superconductors previously discovered must be cooled, many of them to very low temperatures, making them impractical for most uses.

Now, scientists have found the first superconductor that operates at room temperature — at least given a fairly chilly room. The material is superconducting below temperatures of about 15° Celsius (59° Fahrenheit), physicist Ranga Dias of the University of Rochester in New York and colleagues report October 14 in Nature.

The team’s results “are nothing short of beautiful,” says materials chemist Russell Hemley of the University of Illinois Chicago, who was not involved with the research.

However, the new material’s superconducting superpowers appear

The assembly designed for the third SULTAN cable test features two 3-meter VIPER HTS cables in parallel and connected with a copper joint at the bottom; cryogenic helium and electrical current are injected at the top.once installed in SULTAN. The outer superstructure provides structural support to react the enormous lateral electromechanical body loads generated within the cables during testing. A unique aspect of this design, provided by the materials and the trapezoidal extension at the mid-plane, is the ability to axial strain the cables during testing to better replicate the conditions that would be experienced by VIPER cableswithin a high-field magnet.

Scientists have long sought to harness fusion as an inexhaustible and carbon-free energy source. Within the past few years, groundbreaking high-temperature superconductor technology (HTS) sparked a new vision for achieving practical fusion energy. This approach, known as the high-field pathway to fusion, aims to generate fusion
