China joined the quest for an enormous, internationally cooperative nuclear fusion reactor in 2023. Now, they’ve reached a milestone by generating its magnetic field for the first time—a field that is entirely new in tis design. The “artificial sun” reactor, Huanliu-3 (HL-3), is a tokamak run by 17 collaborating labs and facilities around the world. But the much-ballyhooed quest to make energy using these huge reactors still has a decade or more to go, with a lot of misinformation in the mix.
