Actually, the MC34063 chip and LT3958 chip integrated circuits are already using BEMF for step up voltage.
When running in BEMF mode the highest efficiency is achieved due utilization of coil's reactive power. The active power is used only to make magnetic field on the coil which is making high voltage when collapsing. That is being collected to the output capacitor.
To improve this circuit one thing is needed:
When the power source current the core of the inductor is not gaining magnetic field instantly (unlike electric field). The power source's current is used in magnetic field expansion inside of the inductor core. Due nature of this circuit we want much BEMF as possible so there is a way to gain more - the modulation of the input signal. This will improve efficiency dramatically when catching up the resonance with the coil.

Hi T-1000. I have already pointed out to you that inductive switching spikes (AKA flyback spikes) are not back EMF.
These are two different things.

No point in that Nick because as alien says, he has given us all the clues we need to progress. Who's going to be first to post a self-running replication I wonder. I reckon Dog is already hard at it. 

  The thing is we don't have all the needed information to properly replicate Nelson's device. All we have is a driver diagram, of a possibly different driver than what he used in the self runner boxed video. As there's no copper shielded transformer mounted on that board, as seen on the previous video.
  There's no wiring directions, nor do we even know what some of the components are, like storage capacitors, nor what anything else is.
  The long black tapped capacitor is actually a long red storage cap, 470uf, 315v DC. As seen on this video below:
https://www.youtube.com/watch?v=2UUiDqaTOWg

   Are we to guess about the rest?

Hi Nick you are wrong about the capacitor , is not the red 470uf, 315v DC  but a home made hv cap you can see in that video that home made cap https://www.youtube.com/watch?v=RqE9FUd252I .

if i short the red cap will blow up for sure the wire or my fingers  like that https://drive.google.com/file/d/0ByZY5hj0h0hXXzg2ckxJakpHMlU/view?usp=sharing .
You only need to have more attention to details when you see the things, because is very very important in that type of research .

Zeitmaschine :  ,

I will have pleasure see you use the 10 batteries of mobile phone and replicate the same "fake" but only in 10 minutes not in 30 minutes like i show . but have careful because you could hurt lol and i really talk serious ..
my opinion of you already formed, and face to your speech seem somewhat limited technically, but I hope to see what you can do if accepted the challenge to show the prowess to replicate the same with the batteries you speak ..... ..

Verpies :

I would, happy to take the test you refer, but as I said in lasts posts this circuit is in my house in Portugal like most off them , i don't bring my old circuits with me in the "pocket" and right now I'm in Germany working on another project  and thus it is impossible to satisfy your request about the theme of density of batteries i think that there would be impossible to do as Zeitmaschine said but we'll see if he accepts the challenge and re-creates the same effect... we will see

T-1000:

I will not stop to talk or give opinions when i want , only because some moron make depreciative about what is my work  , but i need to focus in my actual project ;  I can not swim all time in a sea of sharks    i have no time or patience , i'm a bit temperamental sometimes (maybe my big defect) , and even that, is supposed i not share nothing in the time i work in the actual project in Germany i sign that in my contract ,  but I am a stupid and let me lead by my personal values that i have but even that  you see what happens .  I spend some ,hours yesterday to make the circuit of wireless transfer to show a example ... how i'm so stupid sometimes....


Alien Gray

You have true , i share very good information but most want the meal already made .

To the people that i talk in PM ,thanks and i only wish that in the end they can recognize my contribution  if succeed in their goals .

good luck to everyone
and to some learn to have humility


 

Verpies :

Oh, I would not dare to request anything of you Nelson.

I was merely responding to Zeit and T-1000 how their battery trepidations can be dispelled in an easy and scientific manner.
If I were doing a video of a self-runner, I would also consult Hoppy on how to make it as to remove any suspicions of x-wires.  He probably would have me use a Hula-Hoop push-through and spin ...or something like that.

  Geo:  Well, thanks for the clarification concerning the capacitor. But, we see the long homemade black tape covered capacitor, and still don't know what it is,  or what it's doing there.  Is a HV storage capacitor?  Like the red one, which you previously mentioned is a storage cap.

Watch this video carefully:
https://www.youtube.com/watch?v=tDh7Uw5XC_w

That is 1600 volt peaks, rectified unipolar pulses. Single wire, no closed loops, therefore amperage is flat zero, no electron flow and no magnetic field, purely electric agitation of the Aether.

Now think about the classical electromagnetic model.  Remember it?  The red sine wave and 90 degrees to it the blue magnetic sine wave.  Completely yank the blue magnetic sine wave out.  It's gone.  Actually it was never created.

So we have a purely electrical disturbance of the Aether.  Here's where things become rather humbling...

You all remember Lenz Law right?  That thing stopping us from our dreams.  Ha!  Lenz Law is a godsend and here's why...

When a purely electric disturbance interfaces with a load (lamp, coil, motor, whatever), what happens?  Lets take the case of a coil connected to a lamp to make it easier to visualize.  Suppose the coil begins to vibrate from the electric field we have created.  Does it not generate a reverse magnetic field to counteract the magnetic field inducing it?  But we have no magnetic field inducing it, so there's nothing for this magnetic field to butt heads with.  Lenz says it will be reversed, in opposition to the field.  We do have a field, but it's only electric.  Add it up, or better said, multiply it out.  You have an electric component (voltage) and a magnetic component (amperage).  That would be watts my friend, real power.  We didn't have to do anything but walk into the room and Lenz created us a magnetic field to go with our electric field.  Could it be any more simple?

Those filament lamps Nelson was touching on metal objects, lighting them up.  You think it's magic?  No, it's volts times amps.  You just need to see where each part is coming from.  Volts you make, amps you get for free.  Just be real sure you only make volts.  If you make a Hertzian electromagnetic wave, Lenz will happily make you an opposing magnetic wave to wipe all your effort away.  All you want to do is put a coil of wire into motion, just electric motion.  Nature will do the rest.


Keep in mind this is all coming from me, a brain dead, ridiculous idiot.  Don't believe me, just ask MileHigh.  He'll gladly set you straight if that's where you want to go.

Good Evening Dog-1

Believe you just hammered the proverbial nail on it's head........

This looks like the correlation between Nelson's post regarding the *extra* _ third coil.

Void ,
myself many times have some difficulties to linking and apply in practical my ideias;)  Is normal in research Work  because some of this informations are most of time "underlines" .
The most important sometimes is try to not let hour brain polluted because are so many information and different opinions about  this type of subjects .
about the post of Grumage with my old video is really a scissors  make contact with ground but in end of video in last minutes i show without ground , but that prototype are to old (8 months) but i  have that box yet in my home in Portugal, like other smaller basic circuits that i make  to record myself  that great things are made with first small results. .
I think the important at present is understand how to replicate the extra coil circuit first and to that Lost Bro start sharing a good information .
 If we have a big problem , better don't try to solve that in one shot ; better divide the big problem in small parts and it will more easy the journey  until end

good luck

Tesla's *extra* coil is only galvanically connected by a single wire, ie: Not inductively (k=0), so it will vibrate freely without said magnetic interaction with the Primary/Secondary which drive it (extra coil).

take care, peace
lost_bro

In the classical electromagnetic model that circuit is closed by pF stray capacitance.  That's why it does not work with HV DC and pulses are necessary.

It should also be borne in mind that the energy source from the bench supply is supplying real current to the PWM generator, which is also closed loop and in turn is pulsing the bifilar coil.

Remember that Nelson said that there is a power supply needed to run the oscillator, so until we know the nature of that supply, we are unable to work out if his device is truly running overunity.

There is a Don Smith video where he has a large plate of aluminium, perspex, then another aluminium plate where he demonstrates that experiments but misses out the importance of the experiment, the second plate is getting charge from the environment but does not show current draw on the primary side.
