Technology has no bounds. We cannot replicate the Sun but can actually create the same kind of fusion energy. A superconducting fusion device, the Korean Superconducting Tokamak Advanced Research or KSTAR, also known as the Korean artificial sun, has recently set a new world record. It succeeded in retaining a plasma temperature of 100 million degrees Celsius for 20 seconds. The Sun’s core temperature is 15 million degree Celsius. KSTAR is a part of Korea’s contribution to the International Thermonuclear Experimental Reactor (ITER) nuclear fusion research project, that is being built in southern France. It’s ultimate aim is making nuclear fusion power, which is an unlimited source of clean energy. Nuclear fusion works by combining two atomic nuclei into a larger nucleus to release energy.
