South Korea’s ‘Artificial Sun’ Breaks World Record

South Korea’s magnetic fusion device, the Korea Superconducting Tokamak Advanced Research (KSTAR) has set a new world record for fusion.

It achieved a temperature of over 100 million degrees Celsius for 20 seconds.
The Sun burns at 15 million degrees Celsius. By comparison, the KSTAR was able to achieve a temperature of over 6.6 times more than that of Sun’s.
The KSTAR has often been referred to as South Korea’s “artificial sun”.
It is a part of joint research conducted with Seoul National University and Columbia University of the US.
In December 2020 China powered up the HL-2M Tokamak reactor, which managed to heat plasma to a temperature of 150 million degrees Celsius but for about 10 seconds.

Why Fusion Devices are Future of Energy Source

Fusion devices mimic the same reactions that take place inside the Sun and could potentially provide a powerful and limitless source of clean energy by releasing massive amounts of energy that can be converted into electricity.
Unlike nuclear fission, it creates little radioactive waste and is considerably less dangerous, but is also more expensive.
