- The Scientists in Germany have achieved a major milestone in limitless energy through nuclear fusion.
- With the Wendelstein 7-X reactor, researchers sustained a fusion plasma for 43 seconds, setting a new record.
- It is the world’s largest operational stellarator.
- This is a type of fusion reactor that uses powerful external magnets to confine superheated plasma.
- The now-decommissioned JT60U in Japan and JET in the UK — have historically led fusion experiments.
- In 2023, China’s Experimental Advanced Superconducting Tokamak (EAST), also known as the "artificial sun," held plasma for 1,000 seconds.
