Scientists Break Record , for Most Energy Produced , in a Fusion Reaction.br 'Vice' reports that a lab in Britain has br set a new record for producing the br most energy in a fusion reaction.br The achievement paves the way for the next br generation of fusion reactors and brings the planet br closer to possessing boundless clean energy.br The Joint European Torus (JET) reactor br managed to produce 60 megajoules of br output in a reaction lasting 5.2 seconds. .br Beyond setting a new record, br we achieved things we’ve never br done before and deepened ourbr understanding of fusion physics. , Ambrogio Fasoli, Program Manager at EUROfusion, via 'Vice'.br 'Vice' reports that JET is a tokamak reactor, br which is one of the two favored designs br for developing practical fusion tech. .br Experts say that bringing fusion experiments to br a commercial plant presents a number br of engineering challenges to overcome.br JET has operated as close br to powerplant conditions as br is possible with today’s facilities, br and its legacy will be pervasive br in all future power plants, Sir Ian Chapman, U.K. Atomic Energy Authority CEO, via 'Vice'.br It has a critical role in br bringing us closer to a safe br and sustainable future, Sir Ian Chapman, U.K. Atomic Energy Authority CEO, via 'Vice'.br JET's achievement was the final accomplishment br for a multi-nation experiment, as the br reactor has since been decommissioned. .br In late 2025, JET's replacement, the International br Thermonuclear Experimental Reactor (ITER),br a larger project that includes 37 countries, will launch.br Our successful demonstration of br operational scenarios for future fusion br machines like ITER and DEMO, br validated by the new energy record, br instill greater confidence in the br development of fusion energy.
