In South Korea, the “artificial sun” was heated to 100 million ° C: this is 7 times hotter than the stars.

Engineers managed to heat up the reactor to 100 million degrees Celsius. This is seven times the temperature of the Sun. The heated plasma was held for 30 seconds. The scientists' next goal is 300 seconds. The principle of operation of a nuclear reactor is completely copied from the Sun. The device uses nuclear fusion in the same way to obtain infinite energy. The reactor is located in KSTAR. It is planned to be used for energy production in times of crisis. One such "artificial sun" can provide energy to entire cities and small countries. The cost of this "monster" remains unknown.
