Fusion - fusion - fusion

MIT's Fusion Reactor Broke a World Record Right Before the Feds Shut It Off

 '' The fusion reactor hit this milestone near midnight on September 30th, the very last day of its operation. “We were pushing parameters purposefully at the end, to see if we could exceed the value we’d achieved in the past,” Martin Greenwald, the deputy director of MIT’s Plasma Science and Fusion Center told Gizmodo. “It was pretty exciting.” ''

China's Experimental Fusion Reactor Hits Major Milestone | Popular Science

"A Chinese fusion reactor managed to sustain plasma at temperatures of over 90 million degrees for 102 seconds ...

This achievement at the Experimental Advanced Superconducting Tokamak (EAST) in Heifi, China, comes just days after German chancellor Angela Merkel inaugurated the Wendelstein 7-X, another experimental fusion reactor.


EAST is a tokamak, a doughnut shaped device originally designed by the Soviets. It holds the plasma in place using magnetic fields, and operates in pulses. The Wendelstein 7-X, in contrast, is a stellarator, a similar design but one that can theoretically operate continuously, like an artificial sun. "
