Story summary

The German Wendelstein 7-X stellarator has made waves in nuclear fusion by maintaining plasma for an impressive 43 seconds, thanks to a cutting-edge frozen hydrogen pellet injector from the US Department of Energy. This achievement stands out, as its smaller plasma volume enhances its significance compared to the UK's JET tokamak, hinting that stellarators could lead the way in future fusion technology.
