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 makes the sun and other stars shine, by fusing together two atoms to unleash huge amounts of energy.The Korea Superconducting Tokamak Advanced Research device , known as the "artificial sun", at the Korea Institute of Fusion Energy in Daejeon, South Korea.
Sustaining these high temperatures "has not been easy to demonstrate due to the unstable nature of the high temperature plasma", he told CNN, which is why this recent record is so significant. What the scientists are doing in South Korea will feed into the development of the International Thermonuclear Experimental Reactor in southern France, known as ITER, the world's biggest tokamak which aims to prove the feasibility of fusion.
They produced 69 megajoules of fusion energy for five seconds, roughly enough to power 12,000 homes for the same amount of time.
