Developing nation China makes artificial Sun — nuclear fusion at 70 million degrees for 17 minutes

Amazing what countries too poor to commit to Net Zero get up to

China’s EAST Tokamak Reactor in 2015

China is the fastest growing nuclear power in the world, poised to have the largest fission fleet by 2030. But it has just scored a bit of a leap forward in nuclear fusion:

China’s Artificial Sun Breaks Record by Hitting 120 Million F in Race for Nuclear Fusion

Robert Lea, Newsweek

The team at China’s “artificial sun” fusion facility—the Experimental Advanced Superconducting Tokamak (EAST)—have said that on December 30, 2021, they were able to generate 120 million degrees Fahrenheit plasma (around 70 million degrees Celsius) and hold it for 1,056 seconds.

Tokamaks, like the donut-shaped EAST reactor, are often referred to as “artificial suns” as they are devices that replicate the fusion processes that occur within stars.

In the Sun, two hydrogen atoms are bashed together to make one helium atom, plus lots of energy. In stars the temperature only needs to be 60 million F (or 33 million degrees C) for that to be self sustaining, because the pressure is so much higher at the centre of the Sun. Here on Earth, […]
