German Fusion Reactor Breaks Record with 43-Second Plasma Run
Scientists in Germany made a big step in creating clean energy.
Using a reactor called Wendelstein 7-X, they kept a super-hot gas (plasma) going for 43 seconds.
This is a record!
The plasma reached over 20 million degrees.
This helps them get closer to using fusion, like the sun, to make energy.
Fusion could provide clean energy without pollution and help fight climate change.
German scientists achieved a new record with the Wendelstein 7-X fusion reactor.
The reactor sustained plasma for 43 seconds, a new record.
Plasma reached temperatures over 20 million degrees Celsius, peaking at 30 million.
The experiment set a new record for the triple product, a key fusion benchmark.
Fusion aims to provide clean, sustainable energy without carbon emissions.
