Here’s more news as a followup to “EmDrive – Propulsion Revolution” – NASA continues to test the EmDrive reactionless thruster with promising results, and they’re making progress with theory development to explain the otherwise inexplicable test results. There’s a report that experiments show EM drive works in a vacuum, thus dispelling the leading debunking theory that the measured thrust was an artifact arising from internal thermal convection. What’s more, the working theory helps explain disparate results between U.S. & UK & China teams.
This is exciting! Read the latest here, although sadly there’s no word yet on what it sounds like.
Update 2021-04-02: Looks like the EmDrive is a bust; the observed effect was the result of thermal effect. Bummer.
