Germany's Wendelstein 7-X sets new performance records in nuclear fusion research

Good news! Good that Germany is not entirely relying on intermittent solar and wind power!

Stellarator vs. tokamak!

"On May 22, the latest experimental campaign concluded at the world's most powerful nuclear fusion device of the stellarator type. Through collaboration between researchers from Europe and the U.S., Wendelstein 7-X achieved, among other milestones, a world record in a key parameter of fusion physics: the triple product. This value now exceeds previous tokamak records for long plasma durations. ...

In the OP 2.3 campaign, which ended on May 22, the international W7-X team achieved a new world record for the triple product in long plasma discharges: on this last day, they sustained a new peak value of this key fusion parameter for 43 seconds. Wendelstein 7-X thus surpassed the best performances of fusion devices of the tokamak type for longer plasma durations. ..."
