Physicists from UNLV and the University of Rochester announced a major discovery on Wednesday.

It is superconducting, which means electrical current flows through it with perfect efficiency - with no energy wasted as heat.

Compressing simple molecular solids with hydrogen at extremely high pressures, University of Rochester engineers and physicists have, for the first time, created material that is superconducting at room temperature.

In the period after the discovery of high-temperature superconductors, there wasn't a good conceptual understanding of why those compounds worked. While there was a burst of progress toward higher temperatures, it quickly ground to a halt, largely because it was fueled by trial and error. Recent years brought a better understanding of the mechanisms that enable superconductivity, and we're seeing a second burst of rapidly rising temperatures.

Since its discovery more than a century ago, superconductivity has come to play a powerful role in many modern day technologies, such as maglev trains and MRI scans, but its utility has been limited by the need for extremely cool operating temperatures. Scientists are now claiming a big breakthrough in this area, creating what they say is the first material capable of superconductivity at room temperature.

A team of physicists in New York has discovered a material that conducts electricity with perfect efficiency at room temperature — a long-sought scientific milestone. The hydrogen, carbon and sulfur compound operates as a superconductor at up to 59 degrees Fahrenheit, the team reported today in Nature. That’s more than 50 degrees hotter than the previous high-temperature superconductivity record set last year.
