  If Ruslan's comments are meant to confuse us, they've done a good job of it.  But, I think that he is the one confused, and not really knowing what is causing the amplification effect. Even though he has shown (to some extent) how it might work. They may still be holding out, and not spilling ALL the beans.
   Akula was presuming that NMR is the cause of the Extra energy.  Which is Wrong!  Then Ruslan copied that mistaken IDEA, also.
  At first Akula mentioned "Earth Magnetic Resonance",  as being the input source for the illusive extra power.
  They don't really know. And even current science today does not know what the source of electrical power is, or where it's coming from, that appears when a magnet is past by a coil.  As you can't see it, and can't measure it.  So, it doesn't exist???
 
   There is only one non man made power source- the Aether. And everything we see (or don't see) is derived from that source, this cosmic soup.
 
  Still don't believe it, huh??? Or still don't believe what Tesla was saying many many many times. 
Why not?
  Maybe we are the ones that are still confused... and main steam science would like it to stay that way. For a reason.

  Hoppy:  You mentioned: "I'm hoping that Geo and Nick take his advice and show their devices running on a battery in any future videos they post. I see nothing unusual about the operation of the devices and the 'effects' I've so far seen demonstrated, where they are powered by grid connected PSU's."

   I'm hoping that "batteries" won't even be needed, to show self running.  There are enough videos out there showing this to be the case.  Running on batteries still won't prove self running, or not. It may be a step in the right direction.  But, also, NO scopes or anything else that's also connected up to the grid, as well as to the device.
As what's the use of running on batteries, when the test gear is all connected to the grid, and also to the device.

Of course not but the point I'm trying to make is that the strong 'effect' we see when the earth lead is connected, is to be expected when running on a grid derived power supply. There will also be an 'effect' when running on batteries due to capacitance coupling from battery to ground but it should be less. The test equipment can be made earth free.

I was reading some comments from Ruslan last night and it is now even more confusing.  He says: "  Forget about that stupid pulses, my device work on the principle of mixture of Longitudinal and transverse waves.  How many people has done this?  No one of you!!  ....." 

What are your opinion about the principle of this device. Let's elaborate it here together.

The Ruslan effect, The art of confusion!

After making the Ruslan cycle more than one times, for me there is only one way to look the device at. "Bemf generator'' is the right term to describe it. Transverse wave is the low KHz sinus from yoke. Longitudinal waves are the bemf spikes imposed on it. But needs art to bring this all together. Ruslan is a great engineer. Don't be fooled with his childish behavior.       

Just keep in mind DC signals are composed of AC harmonics.

I think the whole trick to it is having the proper pulse width for each harmonic, then when they combine you get something very similar to a typical digital square wave with an offset voltage.  I watched Erfinder do this with his coils, but he didn't explain exactly how he did it.

Also, what is the reason of the opposite wound coil at the end of Tesla coil of Ruslan's device?

I can't say for sure, but I bet it's the same reason the grenade coil has 96 turns in one direction and 72 turns in the other.  Must have to do with setting the proper inductance to achieve the desired running frequency while still maintaining the proper wire length.

I've been trying to deeply analyze the construction of the grenade coil and if my hunch is correct, this is a very sophisticated coil--turn ratios, wire length, velocity factor, turns direction, inductance, impedance, magnetic & charge influence, they all have to be just so to even allow the effect to manifest inside.  That in itself is difficult enough, then you have to drive this coil properly.  It's really making my head hurt.  Whoever came up with this gadget really understood a lot about electricity.  I can promise you, not even TinselKoala could figure out what all it's doing in a day or two--probably why he hasn't elected to hop onboard, because it would show just how much he doesn't know.   

Ruslan corrected him self saying it was wrong design. His new grenade is wound as a normal transformer (back and forward for all three section) as far as I know.  he said the old design was very unstable. I am going to make a newcoil today. I still have a old design too.

So are you saying all 144 turns in the same direction?   That would be interesting if it still works.  Would make it much more like the Dally coil.

Dog one, how do you make the layers of your grenade? 144T are 48+48 and 24+24. Where are the last two layers of 12T each? I have a total of 168T. (48+48, 24+24, 12+12=168T)

Thanks D1

I think i'll give it a shot these days to wind my coil same direction to see how much lower my resonant frequency goes (due to higher inductance)
