South Korea’s Artificial Sun :
We are witnessing freak weather events more often than ever before due to the long history of fossil fuel usage unconcerned about nature.
And now realizing the threat, the world is racing to find alternate and clean energy sources.

Adoption of clean energy like solar farms, wind farms, hydropower plants is widely expanding around the world to curb the devastating effects.
But the Lithium-based batteries may not be enough to fulfill the demand of the rapidly growing population and expanding power-consuming technology.
Hence countries are coming up with more and more advanced solutions to quench the thirst for energy, say nuclear fusion reaction, the reaction that’s happening in our star that produces energy beyond our imagination.
The energy produced by the sun for one second is 1000s of times greater than the total amount of energy produced by humans since the beginning of the 20th century.
And now the South Korean government is gearing up to harvest energy from Korea’s first artificial Sun – KSTAR.
The Ministry of Science and ICT announced the plan at the 16th National Fusion Committee held at the Korea Institute of Fusion Energy and finalized the “4th basic plan for the nuclear fusion energy development (2022-2026)”.
South Korea had already achieved creating the artificial Sun and maintaining it at a whopping 100 million degrees of star-core level temperatures for 30 seconds in 2021.
But to commercialize the nuclear fusion reaction of the artificial sun, it must be sustained for a minimum of 300 seconds.
The South Korean Science Ministry has set its targets and plans of its policies for nuclear fusion energy development to develop technology that can handle this supreme temperature for 300 seconds by 2026.
Artificial Sun – KSTAR reached 100 million degrees for 1.5 seconds in 2018, for 20 seconds in 2019, and 30 seconds in 2021 which is the longest sustained duration of such temperature in the world.
South Korea has already plotted ‘eight-core technologies’ required to demonstrate future nuclear fusion power generation from the artificial sun.
The researchers are expected to perform the preliminary concept design test in 2023 to harvest energy to produce electricity.
