China: Proof-of-Concept Testing of EmDrive Ongoing in Space Station (Popular Science)

Since an article was published in The Journal of Propulsion and Power in which the authors confirmed in experiments that apparent propulsion-less thrust was detected in and EmDrive type device, there has been an increasing amount of interest this technology which many people say should be impossible in terms of known physics. Despite the skepticism, it looks like China is taking it very seriously. Thanks to Artefact for posting a link to a story in Popular Science about this:

Dr. Chen Yue, Director of Commercial Satellite Technology for the China Academy of Space Technology (CAST) announced on December 10, 2016 that not only has China successfully tested EmDrives technology in its laboratories, but that a proof-of-concept is currently undergoing zero-g testing in orbit (according to the International Business Times, this test is taking place on the Tiangong 2 space station). (

They do not state that the results are positive, but one might assume that if they are moving from the lab to space, and that they are openly confirming the research program, that they would have some reason to believe that the technology is real and useful.

The PopSci article discusses how even with a tiny amount of thrust, space applications of EmDrive technology could be enough to drive spacecraft efficiently in deep space in the absence of friction and gravity.
