Stubblefield coils (bifilar) and speculations

@ Gary:

Good idea about stacking.

Gary,
Just so I can keep up, is this a pancake on the ground?
or stacks of pancakes?
Maple sysrup?

WHat I am thinking now ........ to make a non  galvanic  earth battery  I could   start  with a  sheet of plastic .
Hot  glue  copper  and  iron  wires in a spiral  around a  center  hole   ( through the plastic. )

I guess  you could  call it a stack of pancakes .........  and  no syurip  please .........I am  on a low  galvanic  diet .



What I am thinking right now .......is that  using  small  wires sizes  it would be  pretty cheap  to wind a few of these coils
like you  are doing  with your coils .




With a  core through the middle of them .......its kind of like a modular  earth battery .

Tesla/Stubblefield set-up whereby you have a pancake bifilar except we use the old bare cu and fe wire insulated with cotton and add an iron core.  The core, of course, would be more like a disk than a rod. 

What do you think?  I would like to see what this puts out.

Bill

I probably should go to sleep instead of ask another question but...

I can't picture this. the pancake is flat on the ground like the picture ok. And the core is a sheet in the form of a disk? I can't follow the core part?

Anyway it seems to me that it wouldn't need the corepiece or anything else the way he wrote the patent. but lets say it does and you are going to hold onto some of the mag field you produce with the coil as in the NS core piece 1 primary, where would you put the core?

a pic a drawing?

ps

yes gary, that is like what I thought Bill was doing. stab the middle like the record spindle.

@ All:

OK.  I have been reading the last several posts and (Oh no, not again) may have an idea.  I noticed on the Tesla patent for the pancake coil that all the wire (bifilar) were insulated and, as Jeanna pointed out, no core.  Way back when we were wondering if it was better to have a short coil with many, many layers or a longer coil with a few.  so, what I am thinking is trying a Tesla/Stubblefield set-up whereby you have a pancake bifilar except we use the old bare cu and fe wire insulated with cotton and add an iron core.  The core, of course, would be more like a disk than a rod.  This would be easy to wind.  An old record player would be handy at this point.  Not to use the motor but, you could hand spin it while winding and keeping it flat.  What do you think?  I would like to see what this puts out.

The  record player  idea might work great  for  small wired

You  would have to glue   the  wire to something  every once in a while .

I  remember  another site people were  winding  pancake  coils for something ......can't remember  what they were for   you   have to pull  on the wire some as you wind  to keep  the winding tight.  ...... if  the wire is not  secured well .......you  will  get to a certain  point and the  wire will pop off  of other windings ........once  it pops ......you  are done ...no chance of fixing  it.   

one of the ways  they  were  doing it is  winding  the pancake  between to heavy plastic  sheets .

Jeanna:

Yes, you put the core (disk) in the middle.  That is not what Tesla was doing.  His wires were both the same and were not bare either.  I was talking of combining both ideas.  Copper and iron bare, and a core, but pancake style winding.  Maybe nothing here.  Maybe something.  I didn't consider Gary's idea of stacking.  As he said....modular.  You want X power....you need X number of pancakes.  Also, as he said, wired in series or parallel depending on the requirements.
