The Promise And Perils Of Superconductivity And Fusion Energy

Superconductivity, or the idea that certain materials are capable of conducting direct current (DC) electricity without resistance or energy loss, has been an elusive phenomenon for well over a century.

In 1911, a Dutch scientist named Heike Kamerlingh-Onnes found that mercury could superconduct electricity at very low temperatures, a monumental discovery for which he was awarded the Nobel Prize.
