Humanity has taken another, albeit small, step towards the domestication of thermonuclear energy. South Korean physicists from the National Institute for Thermonuclear Research in the city of Daejeon managed to keep the plasma from superheated hydrogen gas in a stable state for 70 seconds using a superconducting tokamak reactor - KSTAR.
Plasma is the fourth state of matter (the first three are solid, liquid and gas). An example of plasma is lightning and the processes occurring in the sun.
The previous record for plasma confinement time held by the MIT Fusion Center has been improved by 15%. However, most likely, this record will be broken. The world's largest Tokamak reactor is currently under construction in France. The participants in the future project hope to generate a plasma with a temperature of 150 million ° C.
