Breakthroughs from two rival experiments, Germany’s Wendelstein 7-X and the Joint European Torus, suggest the elusive dream ...

Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy. Fusion reactions take place in a state of matter called ...

Nuclear fusion occurs when two light atomic nuclei combine to form a heavier nucleus, releasing vast amounts of energy. This reaction powers the sun and other stars, where extreme temperatures and ...

The amount of energy released in a nuclear fusion reaction can be many times that of a chemical reaction. Fusion is also carbon-free, which is why it is sometimes labeled as the “holy grail ...

A world record for nuclear fusion has been smashed after an ‘artificial sun’ reactor was able to maintain a plasma for more than 22 minutes. The WEST reactor, in southern France, is at the ...

KSTAR, KFE’s fusion research device which it refers to as an “artificial sun,” managed to sustain plasma with temperatures of 100 million degrees for 48 seconds during tests between December ...
