Thanks a lot for such a great answer. Thanks again for retyping it after FF died on you. Sorry about the lack of line-returns in my previous cite.
You make a great argument - and I'm not sure that I can respond meaningfully to it. By all means stop before you start charging me tuition fees!.
This is what I got - the 'EM drive' delivers approx. 1.2mN/kW
My understanding (and WP is my friend) is that 1W = the work required to keep an object moving at 1m/s when there is an opposing force of 1N.
So, we have a cost of 1kW of work for 1.2mN of force. To me that seems unbelievably inefficient (and hardly worth making a hoo-hah about) and certainly no basis for perpetual motion. As I see it there is likewise a massive difference between 1.2mN/kW and 1kN/kW - the first is inefficient, and the second is completely impossible because it's unity - and unity doesn't leave any space for entropy.
Now, as for 1/c - and I'm not ready for the 'quantum vacuum flow' that the paper goes into; I get where you are coming from 1kW/c suggests a theoretical maximum of 0.003mN so I'm calculating that the reported thrust is 359.751 times (I will give you 500) stronger than it could be it it depended upon EM alone.
So, let's assume that the measurements are accurate - we can rule out 'normal' EM pressure - it may contribute but it's two orders of difference too weak. What does that leave us with? The weird graphics show electric force (big red arrows) and lots of swirling magnetic blue arrows. Given that electrons have quite a bit more oomph than their photonic cousins, I would go for saying that they've got something to do with the measurements being read off. However, that just opens up another puzzle: electrons have mass, and therefore whatever motion that is imparted them has an equal and opposite reaction.
My guess is that we are looking at half of the measurement. The other half shows the 'Test Article' swinging back as much as it's been pushed forward. If you put me in a crate and hang it from a rope, I can probably get the crate to swing - and it's not very interesting. I doubt that the figures have been fabricated - but in the end, I am probably with you - there's some BS in there somewhere. (and I'm not talking Boron-Sulphur compounds). .
So - you can chalk this one up to a victory. Just took me some time getting there.
