A magnetic doughnut with a hot plasma filling has produced a record 12 megawatts of nuclear fusion power for a little less than a second.

Sustainable fusion power is still a long way off: heating the atoms and keeping them confined required twice the amount of energy released. But Martin Keilhacker, JET’s director, says the reactor will run in other configurations in coming weeks. “We hope to do better,” he says. More on these topics:
