YouTube Video on EM Drives
There are scores or perhaps even hundreds of online articles and videos on the topic of EM (Electro-Magnetic) Drives. However, only a handful are credible and useful. My favorite to date is this YouTube video presentation from PBS Space Time, "The EM Drive: Fact or Fantasy?", dated January 11, 2017 (first 9 minutes covers the EM drive). It is written and hosted by Matt O'Dowd, an astrophysics professor at Lehman College, Australia.

Pro: In a nine minutes video presentation, Matt explains what EM drive is all about, and its latest controversy as to whether the EM drive is something to be taken seriously. It is well organized, and the extremely hard and complex materials are explained in an easy to understand manner for non-scientists like myself. Matt's explanations are great throughout, but is top notch where he covers the speculations and assumptions about how EM works. Especially helpful was his explanations about how the basic assumptions about quantum vacuum plasma made by the authors of the paper on the EM drive differed markedly from the generally accepted mainstream quantum field theory.
Con: I would've preferred a longer presentation, perhaps a 30 minute presentation instead of the 9 minutes.
