South Korea's magnetic fusion device 'K-STAR' has set a new world record in maintaining the super-hot plasma, a state of extreme heat required for fusion power.
According to the Korea Institute of Fusion Energy on Tuesday, the device, which is used to study aspects of fusion energy, successfully operated at a temperature of 100-million degrees Celsius for 20 seconds generating intense heat that is seven times hotter than the center of the sun.
No other fusion power plant in the world has managed to run for more than ten seconds but the institution aims to maintain this state of plasma for 300 seconds by the year 2025.
The breakthrough will contribute to an international mega project to create a fusion reactor which is similar to the sun.
