The new generator no effect counter B. EMF part 2 ( Selfrunning )

I will mark up one pic here and show you what I thought the config was supposed to be.  If the magnet polarization is incorrect you or Luc can please clarify.  I think we agree on the flux coupling business.

Yes MH, you got it all right! ... also, see my post above on what will be turned.

This is a very good question and a difficult one.
To answer this, it is necessary to know how quickly the near field magnetic field propagates.
I always wanted to measure this speed but I run into practical engineering difficulties.

...there are some that believe that the non-radiative near field interactions are instantaneous, and allegedly a team of Chinese scientists has made a 72g thruster by bouncing microwaves in a CLOSED! container based on this principle

Thanks for pointing to the "emdrive" which is indeed fascinating.  And controversial.
New Scientist published a cover article on this device in 2006, and comments on the article read like comments so often encountered here. 


I invite the reader to look at the "erudite arguments" on both sides, here:

Amazing. 
A wikipedia article provides numerous references:

I'm still looking at this device - it appears that NASA did a test and found a thrust, which does seem to violate conservation of momentum... maybe.  To me, the most important factor lies in repeatability of experiments; not in theory arguments.

  The reaction-less emdrive probably deserves its own thread.  Very interesting.


NASA did conduct tests, July 2014, as reported in wiki:

NASA/JSC Advanced Propulsion Physics Laboratory (Eagleworks)[edit]A NASA team at the Advanced Propulsion Physics Laboratory (informally known as Eagleworks)[26] located at the Johnson Space Center (JSC) under the guidance of physicist Harold G. White is devoted to studying advanced propulsion systems that they hope to develop using quantum vacuum and spacetime engineering. The group has investigated a wide range of fringe proposals including the EmDrive, and related concepts listed below.[/size]RF resonant tapered cavity thruster (EmDrive)[edit]In July 2014, the group reported positive results for an evaluation of a RF resonant tapered cavity similar to Shawyer's EmDrive.[14]Testing was performed using a low-thrust torsion pendulum capable of detecting force at the micronewton level within a sealed but not evacuated vacuum chamber; the RF power amplifier used an electrolytic capacitor not capable of operating in a hard vacuum.[14] The experimenters recorded directional thrust immediately upon application of power.
NASA's tests of this tapered RF resonant cavity were conducted at very low power (2% of Shawyer's 2002 experiment and 0.7% of the Chinese 2010 experiment), but a net mean thrust over five runs was measured at 91.2 µN at 17 W of input power. A net peak thrust was recorded at 116 µN at the same power level.[14][/font][/size]
The experiment was criticized for not having been conducted under vacuum, which would have eliminated thermal air currents. The researchers plan to replace vacuum-incompatible components.[27][/font][/size]
In the coming months, Eagleworks plans to upgrade their equipment to higher power levels, use vacuum-capable RF amplifiers with power ranges of up to 125 W, and design a new tapered cavity analytically determined to be in the 0.1 N/kW region. The test article will be subjected to independent verification and validation at Glenn Research Center, the Jet Propulsion Laboratory, and the Johns Hopkins University Applied Physics Laboratory.[14]

Wow... they're going after it, despite the critics who said vehemently --
"it's impossible!"

Placing an object in a vacuum chamber but then not actually even closing the door much less pumping down to a decently low pressure is pointless.

Placing an object in a vacuum chamber but then not actually even closing the door much less pumping down to a decently low pressure is pointless.

When they started pumping, the electrolytic caps started bulging out so they gave up until a vacuum immune RF amplifier is obtained.
Other than that mentioning a vacuum chamber without a vacuum is pointless indeed.
