Nuclear fusion record smashed as German scientists take 'a significant step forward' to near-limitless clean energy

The Wendelstein 7-X stellarator in Germany has set new fusion records, surpassing previous benchmarks in plasma sustainability and energy turnover. It achieved a record-high triple product using a new fuel pellet injector and microwave heating system. The plasma reached 30 million degrees Celsius over 43 seconds, with an energy turnover of 1.8 gigajoules during a six-minute run. These achievements validate stellarators as a promising fusion reactor design for potential future clean energy production.
