reversing the emdrive orientation and running the same test should show whether the direction of the thrust changes. if it is due to electro magnetic effects interacting with the environment then the thrust should be in the same direction again?
I will run two more tests in the current configuration, and then reverse the orientation and run three more tests. Then I will move the emdrive into null position and run three tests. I won't have anymore test results until mid next week though - have other plans this weekend.

Interesting paper:
Einstein-Maxwell equations for asymmetric resonant cavities:
http://arxiv.org/abs/1505.06917V. CONCLUSIONS
I have shown how a plane wave could produce a gravitational effect inside a cavity that
could be observed using a propagating laser beam inside it. The effect could be unveiled
using an interferometer or observing the components of the laser field outside the cavity.
Components with a shifted frequency, due to the modes inside the cavity, should be seen.
This could explain some recent results with interferometric setup obtained at NASA with a
resonator having the form of a box. A local warp of the geometry due to the electromagnetic
field pumped inside the cavity could be a satisfactory explanation. From a physical
standpoint this could be a really breakthrough paving the way to table-top experiments in
general relativity and marking the starting point of space-time engineering.
Then, I considered a frustum in the form of a truncated cone. I have shown that general
relativity introduce a large scale that makes all the effects really miniscule. For the frustum
I have shown that the gravitational effects can be described by a susceptibility multiplying
the energy-momentum tensor of the electromagnetic field inside the cavity. Due to this
particular geometry, it can be shown that the susceptibility can be made significant by a
proper choice of the geometrical parameters of the cavity yielding thrust without violating
any law of physics. This effect could amenable to observation with a proper interferometric
setup.

That is one powerful, and exciting, statement.

Marco predicts that the gravitational effects being generated in the frustums should scale with the square of the average energy density of the E&M field in the frustum.
That is VERY exciting!

http://www.iflscience.com/technology/rumored-emdrive-paper-suggests-the-controversial-thruster-actually-works/Update (2 September): It has been confirmed to IFLScience by the AIAA that a paper on the EmDrive is being published in December 2016. They said:
“The American Institute of Aeronautics and Astronautics (AIAA) Journal of Propulsion and Power has accepted for publication a paper in the area of electromagnetic propulsion. However, it is AIAA’s policy not to discuss the details of peer reviewed papers before/until they are published. We currently expect the paper in question to be published in December 2016.”

I have a question for the professional physicists on the board:
If photons have a spin of 1, and two photons perfectly overlap in the 'right' way, do the individual spins of '1' superimpose / add up to create a point in space where spin is '2' ? I'm asking because the graviton is supposed to have a spin of '2' and no electric charge (which would technically be the case if two photons overlap 'destructively' at the same point in spacetime, eradicating any 'charge'/electric field component).
BR
CW
Addition of angular momentum is possible in a number of combinations of photons. In QED, in a Gaussian distribution, there is evidence of photons "bunching" into pairs and it's a prediction of the theory. However, there is no evidence for gravitons. They are a fiction, created to quantize GR in the same way we quantize EM. GR does not work this way, as many have realized and have moved on from this fiction.

Double the EM field energy density inside an EmDrive and get 4x the gravational effect inside the EmDrive.
Remember those space warping (well artificial gravity like equivalent space warping) experiments Paul shared with us about shining a laser through a powered & non powered frustum?

Roger's quote is priceless:
http://www.ibtimes.co.uk/emdrive-nasa-eagleworks-paper-has-finally-passed-peer-review-says-scientist-know-1578716
"People all around the world have been measuring thrust.
You've got guys building them in their garages and very large organisations building cavities too.
They're all generating thrust, there's no great mystery.
People think it's black magic or something, but it's not.
Any physicist worth his salt should understand how it works, or if they don't, they should change their profession."
hmmmm...
very unfortunate quote, if you ask me, as such -dare I say - rather populist remark has a very high boomerang tendency...
I understand it comes from years of buildup frustration, of tedious swimming against the main current of scientific consensus, but such a reaction doesn't help as far as credibility goes.
If the EM effect is indeed acknowledged, through experiments/peer review, then R.Shawyer deserves all the credit he can muster, but the backstabbing is - although understandable - really unnecessary...

Understandable? Maybe, but we do bear responsibility for explaining our concepts clearly. Both the student and the teacher ( or two colleagues ) have to be up to the task. I understand it is not always easy to address your critics but it never serves you well to ignore direct questions on or challenges to your theory.

Sawyer never had just a theory through, he had a prototype machine that produced thrust without expelling anything, everyone should have spent there time challenging his claims that produce thrust by building their own, instead of nitpicking over his papers. If they had done may we be a lot further down this road.
An many people just simply dismissed his engine just because it broke one of their gold rules rather than actually bothering to look at it.
One physicist even said it would take his students less than a day to prove it didn't work.
Even if it doesn't work it taken Nasa a couple of years to prove it doesn't work and having also stood up to numerous other tests carried out by experience engineers before hand.

Hi everybody!
An interesting paper which put the problem on the right frame is the Wave-Particle Duality. The paper suggests the relativistic Energy as discovered by Einstein does not address the wave-particle interaction. A new relativistic expression that is absolutely compatible with Einstein's Relativity shows the way to the stars and could be verified during EM interactions (acceleration within an electrostatic field):

It works.
As now reported on many sites, other than NSF, Dr Rodal quoted the EW tests reported consistent specific thrust of 1.2mN/kWrf. You can read the details below.

From these findings, we can create artificial gravitational fields, warp drives ?

All we know is what Paul shared.
Would assume EW have done further work since then.
