Hydrogen sulphide is world’s best superconductor

Date:19 August 2015

Hydrogen sulphide, the chemical compound that makes rotten eggs stink, now holds the record as the world’s best superconductor.

Hydrogen sulphide is produced when bacteria consumes and digests organic matter in anaerobic environments (meaning environments without air).

Physicists have shown that, when solidified, hydrogen sulphide conducts electricity without resistance at -70° C. The hydrogen sulphide is compressed to 100 million bar and cooled below freezing, forcing it to become metal.

Although this seems incredibly cold, it really isn’t. Generally, superconductors function at around -234° C.

What does this mean? Researchers are now one step – or a few degrees – closer to room-temperature conductivity. That could have at-home applications for high-tech appliances, even everyday ones. Better TV sets? You bet. Just don’t expect better TV programming anytime soon.
