Yeah, this whole topic is done at this point.
Shawyer makes claim for 20+ years.
Prof. Yang publishes results of a poorly done experiment seemingly confirming above claims.
EagleWorks joins the effort. First attempt, null result.
Media sensationalizes as media does.
"Believers" in the EmDrive start to appear without any physics (or science in general) background trying to be armchair scientists.
DIYers come out of the woodwork trying to use magnetrons to experiment.
Forum poster on NSF and reddit starts to make extraordinary claims, fails to produce evidence of said claims, disappears for a few months.
EagleWorks sets up Vacuum test, non-vacuum rated equipment fails, results still make it up on the web. Experiment still has serious design issues.
Some fail and realize why, others fail and refuse to accept why.
Prof. Tajmar tries his hand at an EmDrive only to decide his setup is insufficient and results would ultimately be inconclusive.
Prof. Yang alters experiment to move power source onto device instead of feeding it along the balance arm, measurement disappears. Publishes new results, believers won't accept results.
EagleWorks fails to publish to any physics journals, decides to target engineering journals and successfully publishes in a propulsion journal.
EagleWorks results are pretty heavily critique'd in the physics community as well as the amateur physics communities for issues with design.
Skeptics chalk the claims up to noise in the way of thermal effects, lorentz forces, poor grounding, and other issues.
Forum poster on NSF and reddit reappears with even greater claims. Starts spreading false rumors about EmDrive testing on the X37-B and in China.
Most folks have moved on, but there are still hold-outs.
Shawyer doubles down on claims....
Rossi is still better at this game than Shawyer will ever be.
