Korean "artificial sun" breaks world record of retaining high plasma temperature for energy production Updated: 2019-02-14 07:01:04 KST

Nuclear scientists in South Korea have conducted a revolutionary experiment, creating an "artificial sun," taking a massive step toward developing clean nuclear energy.
The National Fusion Research Institute says its fusion reactor managed to sustain a temperature of more than 100-million degrees Celsius, for one.five seconds.
It is first time in the world that the temperature, around six to seven times hotter than the actual sun, was sustained for longer than one second.
This comes as scientists around the world are looking to develop nuclear fusion devices that could mass produce clean power, replicating the natural process that the sun uses to generate energy.
