Then in 1986, scientists discovered a class of copper oxide that displayed the same drop in resistance but at a higher temperature – about 77.2 K (-196°C)..
Researchers at the National Ignition Facility announced that they had achieved net energy gain in a fusion reaction. It could provide us with an unlimited source of green and safe energy.
Superconductors are found in some of the most advanced technologies on the planet, and unlocking their full potential could bring about a new electronic age.
