Scientists generally use a donut-shaped reactor called a tokamak in which hydrogen variants are heated to extraordinarily high temperatures to create a plasma. This is called the artificial Sun because it replicates the reaction of fusion taking place there and unleashes a massive amount of heat energy.
ALBAWABA - CNN reports that scientists at the Korea Fusion Energy Institute (KFE) are trying to operate the KSTAR nuclear reactor at temperatures as hig
South Korea's superconducting fusion device and so-called artificial sun, KSTAR, has received upgrades that will allow it to run for longer periods of time.
