Fusion experiment yields new record energy

When two atoms join together, the laws of physics tell us that a large amount of energy will be released, but the experiments performed so far by scientists to achieve nuclear fusion have always yielded a lot less energy than the inputs. This week, the Lawrence Livermore National Laboratory in California, which uses an approach called ‘inertial confinement fusion’, announced that they achieved a huge improvement in the record energy yield from a fusion experiment. Iacopo Russo heard from Debbie Callahan, a lead researcher on the project.
