If it leaks too much RF, will put it in it's own Faraday Cage.The videos are nice, but until the mechanisms are replicated by an independent third party, it doesn't count for beans. Third party replication and verification is what makes the scientific method such a powerful tool. If the replication experiments are successful, then it'll be time to shout it from the rooftops.

I disagree that they confirmed CofE observed. What was demonstrated was constant angular velocity at constant thrust. That represents zero acceleration. That does not correspond to either a constant acceleration model (non-CofE) nor to a decreasing acceleration model (CofE). What it shows is that an equilibrium was reached between the thrust and the friction at a particular angular velocity.Friction is not our friend because it muddies the waters. It needs to be modelled and it dissipates power to boot. Basically, it complicates the analysis. Nevertheless, one is going to have to deal with it in the data analysis.

If it works, the Twitter verse will do the shouting.

Ensuring that the device is encased and no heat is getting out sounds very sensible, yes.

(It should have a finite size if it had a beginning and an expansion.) Light falling into gravity fields I would think should slow down, (considering the limit when light reaches an event horizon). From inside a gravity field I should think light should still appear to be going c due the shrinking of the ruller. This could give the appearance of the index of refraction (gravitational lensing). Two objects traveling towards each other @ .6c still appear from the God view to be approaching at 1.2c though I suppose the two observers both have their (space/time) warped so it appears to them they are not approaching each other at 1.2c but rather v<c. I mean sure time/space screws our perceptions all up but why not have an absolute frame of the universe or CMB where either we are moving with respect to it or we arent? Or am I missing something. Congratulations! You have just "correctly" described the Polarizable Vacuum Model of General Relativity. However, we do not need the CMBR. We simply define an observer "at infinity" to have a refractive index, K=1. From that perspective, he can observe the relative value of K, for all gravitational fields, where K > 1. If he sees something moving FTL, he will assign that space with a relative value of, K < 1. It is still not a preferred frame, because K can be "defined" as 1 anywhere, and all observations are relative to that definition. Mark Millis has said that the CMBR is a preferred frame. IMO, it doesn't make the Math any easier, it just confuses people. As an engineer, I see all things as relative and take everything with a grain of salt. Todd

Could also put the EM Drive inside a 25mm thick foam box.Are you OK with those changes eliminating any heat anomaly?This dynamic test will only be done once the static tests show significant thrust and there is a input power to thrust curve available. This rotary test is not designed to measure thrust but to show how the power consumed by the EM Drive varies as rotary load varies, which to the EM Drive would be like a performance curve of power versus accelerative load mass.

Heh. Even when it's inside a sealed box?

That's why they're building a high power test of ±1Kw or so, hopefully by July...
