Nuclear fusion breakthrough: Researchers at the Joint European Torus generate record heat

A recent nuclear fusion experiment has set a new world record by generating 59 megajoules of heat in 5 seconds, more than doubling the previous record from 1997. This was achieved by fusing deuterium and tritium to form helium. Although the energy produced is modest, it serves as a proof of concept, suggesting the potential for longer and more stable reactions. The success of this experiment is crucial for the International Thermonuclear Experimental Reactor (ITER) in France, which is supported by multiple governments. The record validates design choices for ITER, which aims to prove nuclear fusion as a reliable energy source in the future.
