ByThe Korea Superconducting Tokamak Advanced Research device , known as the"artificial sun," at the Korea Institute of Fusion Energy in Daejeon, South Korea on January 10, 2022. Scientists in South Korea have announced a new world record for the length of time they sustained temperatures of 100 million degrees Celsius — seven times hotter than the sun’s core —Nuclear fusion seeks to replicate the reaction that, by fusing together two atoms to unleash huge amounts of energy.
KSTAR, KFE’s fusion research device which it refers to as an “artificial sun,” managed to sustain plasma with temperatures of 100 million degrees for 48 seconds during tests between December 2023 and February 2024, beating the previous record of 30 seconds set in 2021. in southern France, known as ITER, the world’s biggest tokamak which aims to prove the feasibility of fusion.
in a fusion reaction. They produced 69 megajoules of fusion energy for five seconds, roughly enough to power 12,000 homes for the same amount of time.
