After China, South Korea also made its own artificial sun and put it into practice, which was more successful than China's artificial sun. According to the website phys.org, this artificial sun of South Korea has been developed by scientists at The Korea Superconducting Tokamak Advanced Research Center. It is a superconducting fusion device. In practice, the artificial sun has been surprisingly hot for over 20 seconds at over 100 million degrees Celsius, a world record.
According to the report, this artificial sun has been jointly developed by the scientists of Seoul National University of South Korea and Columbia University of the United States. According to the report, this device was also tested in 2019, but at that time it was able to maintain such a temperature for only 8 seconds. This was the second test of this device. The first test was conducted in 2018 when the device was able to maintain a temperature of more than 100 million degrees Celsius for just one and a half seconds. "We hope that by 2025, we will be able to keep the device stable at 100 million degrees Celsius for 300 seconds continuously, and that is our ultimate goal," said Yang Xuana, a professor of nuclear engineering at Seoul National University.
