France runs fusion reactor for record 22 minutes

France has upped the ante in the quest for fusion power by maintaining a plasma reaction for over 22 minutes – a new record. The 关键字2milestone was reached on February 12 at the Commissariat à l'énergie atomique et aux énergies alternatives (CEA) WEST Tokamak reactor.

Achieving the dream of commercial fusion power is the Holy Grail of engineering and has been for 80 years. With a single gram of hydrogen isotopes yielding the energy equivalent of 11 tonnes of coal, a practical fusion reactor would hold the promise of unlimited, clean energy for humanity until the end of time.

Small wonder that billions have been invested by both government and industry in the quest to make fusion power a reality. However, while fusion is relatively easy to achieve in the heart of the sun or in a hydrogen bomb, creating a practical reactor that produces more energy than is put into it is another matter entirely.
