ook may be interested in the idea of ​​such a device ktoroya can think boldly called overtone air transformer.


coil L0 - tone
has a height of 157 mm winding
winding diameter of 50 mm
 
Coil L (+1) - first overtone
has a height of 314 mm winding
winding diameter of 25 mm
 
Coil L (-1) j return ("negative") overtone
has a height of 78.5 mm winding
winding diameter of 100 mm
 
 
According to a preliminary idea - the coil L (+1) L0 and L (-1) connected in parallel.
surface coil L0 - tonal wound litz - inductor ...
 
-----
concept ideas.
with the induction coil tones - L0, there will arise
in any case, the harmonics - overtones.
coil L (+1) L (-1) are not only the coils of air
transformer, and at the same time and radiators
emissivity due to its configuration
L (+1) first overtone voice-coil L0 and
L (-1) lower (negative) overtone tone coil L0, ...
that, in this configuration, the transformer winding air,
shall, in connection with the resonance phenomenon to increase the amplitude of the wave
in the coil L0.
 
PS
Also in this gipotetichskom air transformer is observed
equal masses of copper, due to the peculiarity of the configuration of coils,
as indicated by N. Tesla. (Equality of the masses of wire) that ultimately must
  also provide amplification of the wave amplitude in the coil L0.

No, I still here.  I have just been really busy traveling and working.

I really do need to post some videos showing a few of my new projects.  I will not post another AFP type video until next April 1.

I may try replicating Romerouk's Muller build as my next project.

  I've been enjoying your videos, lasersaber.  Keep up the good work!  One of these fine days...

Hi!

Did someone once tried to make Joule Thief with a 220V DC power supply and air core transformer?

I am pretty  sure no one has done that

I am not sure how you would limit the voltage for the base .

Making a JT that would run bigger coils and higher voltages is on my to do list
The way I would do it would be to make a very small normal JT.... then use the output of that JT to drive the  base of an IGBP  or SCR......something that would handle lots of voltage.

IST  played around  driving  MOTs and stuff in a way similar to what I am thinking of........he made some pretty big sparks.
He suggested using NPN and PNP in push pull configuration.

The limit  of  the voltage you could pulse  your coil with would  be limited only by your transistors.......pretty much any coil could  be pulsed.

@Shokac
By that do you mean replace the one battery with a 220VAC mains input and a diode or diode string?
I do have enough Radio Shack battery holders to string together and make an aggregate 120VDC.  Maybe a boost transformer after that?  And an air core toroid?
