It sounded too good to be true – and it was. When the Chinese news agency Xinhua announced on 29 September that researchers had initiated thermonuclear fusion in a brand-new reactor, news organisations worldwide ran with the story. “During the experiment, deuterium and tritium atoms were forced together at a temperature of 100 million Celsius,” Xinhua reported.
“Fusion always causes a lot of media hype because people really want it to happen”
There was just one problem: nothing of the kind took place. “The reports were totally wrong,” Jiangang Li, director of the Institute of Plasma Physics in Hefei, Anhui province, told 鶹ý The Chinese researchers had, for the first time, managed to inject a plasma of ionised hydrogen into the Experimental Advanced Superconducting Tokamak (EAST), a doughnut-shaped machine designed to confine super-hot plasmas magnetically, and the plasma sustained currents of 250,000 amps for up to 3 seconds. But no attempt was made to introduce deuterium or tritium into the plasma, so no fusion can have occurred.

Not everyone swallowed the stories. “I didn’t believe the online reports,” says Chris Carpenter at the Joint European Torus (JET) fusion research centre in the UK. “Fusion is always something that causes a lot of media hype because people really want it to happen.”
