> zero resistance in the material at temperatures higher than 8 Fahrenheit (-13 Celsius), perhaps as high as 44 Fahrenheit (7 Celsius)

> The teams synthesized only about a dust-speck worth of [lanthanum hydride] from expensive ingredients crushed to unfathomable pressures between hand-cranked diamond halves

While the temperatures are amazing (when I was young, superconductivity above 0 Celsius was the stuff of science fiction), the material might not have commercial applications in the near future.

Instead, why not use active cooling and powerful insulation? Like this: https://www.chemistryworld.com/news/world-first-as-wind-turb...
