EMdrive Developments working in visible and infrared light regime.

New Tajmar's conference papers (March 2021) - the first one is about optical EMDrive and similar experiments:

Apparently this is what happened (I was blocked) when I questioned McCulloch about his misleading claims on the testing of Quantized Inertia. McCulloch has been claiming on twitter that Tajmar never tested asymmetric cavities.  A plain reading of Tajmar's paper shows this is not true. McCulloch seems to be purposefully misleading his followers about the various experiments apparently falsifying his theory.

Hah!  Blocking scientific inquiry.  That'll sure help!  I saw one comment at the head of that thread which seems to indicate that  it is possible to design and build an engine that "does not develop any thrust".

"Latest EmDrive tests at Dresden University shows "impossible Engine" does not develop any thrust"

Mike McCulloch, this is not acceptable behavior.

Just build and test these devices as the inventors claim they work. If people like Tajmar proof they don't generate trust, end of story....

It is great to see so many experiments and trials to get EMdrive recognized.

'Academically', if EMdrive was to work, it would violate the conservation of momentum (fundamental ‘symmetry of nature’, invariance in space), which has been the physics foundation for thousands of years and was proved by thousands of experiments.

But rather than give in, it is the best way to keep on trying. Otherwise we would have stuck 100 years behind. Any theory and experiment are steps forward for the technology.
The so-called ‘plateau effect’ (of receiving less feedback than giving effort) is surmountable with persistence and inspiration that it gives.

Good news. According to McCullough[, a] Texas University is now also testing his thruster:

We all will be happy when we can see their analysis and data. When?

[Lariliss]

Thank you for sharing.
As stated, control tests passed, this is really tells the step to result.
Criticism will always be there.
Only where is a good argument, some results may come.

He seems to think within 14 months.

Yeah, but they won't.  I mean, "results" will come, but somehow nothing will ever come of those.

Fortunately or unfortunately, in this case even nothing as output will be really bright for some period. According to results unveiling diligence.

10 millinewtons of thrust from some positive number of watts input is relatively modest.

10 mN = 0.002248 lbf  per how many watts input?

Needs to be less than ~3 MW to beat a photon rocket (~3.3 nanonewtons per watt).

Annnndddd... How much power are they proposing to employ in powering their device?  You don't say.

Nobody knows yet, as no thrust has been generated yet.

Bad news for McCulloch's theory, Quantized Inertia.  It seems he has had his latest paper rejected by a science journal after much work.
