Stubblefield coils (bifilar) and speculations

[1tesla01]

guys,I didnt see anything in the patient about bifilars what am i missing ???Andy

Gary did you get my last post!!!!!!!!!!!!!!!!!!!!!!!!

Andy

I have been doing other things most of the day

Just getting caught  up  now..

In  another  post  talking about   iron windings   you  said.

.High resistance will have more voltage build up behind the resistor helps to increase the protons.(5) (positive and negative ions are constantly looking to balance out

Are you saying that  if we  add a resistor that we will  get more  voltage  from the iron winding?

I have been making the iron  winding as  thick as I could  to keep the resistance as low as possible .

Nope

you  didn't miss anything 

This thread  was created  for   " speculations "   
We were looking  at  Tesla's   electromagnet  and   wondered  how  much like  a  stubblfield  coil  it be if  it was made  with  an iron  winding .

The  idea is .... the  Tesla  pancake  coil ( with an iron winding )   looks alot like  a slice of  a stubblfield  coil

I did mean resistance. When I tested the "human detector" which is what Francis call his little circuit, (The kids called it things like 'zombie detector, etc.  ) I put a potentiometer across those probes (on the left) and found that with a 3 v battery and a 330R resistor just in series with the neg side of things, the light would glow just at 8,000 ohm and was bright with the resistance right up to 1.9Mohm. but it would go off if the wires were simply connected at that point.

I misunderstood your original post, thinking the circuit perhaps worked by added capacitance on the open ends which would allow a current to be established in the open ended wires, thus energizing the bulb circuit.

I am willing to indulge in a thought or 20 about Tesla stuff, but you really lost me here.

You've made several references to Tesla in this thread and as he is the authority in discussions concerning establishing an electrical current in single wire circuits it seemed appropriate to quote him here. The Stubblefield 'voltaic couple' 'battery' you are researching is notable for using wire coils in place of plates, which leads to all sorts of unusual design characteristics, one of them being two 'terminals' for each 'plate', or four terminals for each bifilar coil 'plate cell' - not to mention the iron core you all are fond of connecting to. Figuring out how to wire this 'battery' seems to be a challenge, especially since a current flow is desired along the length of the coils to establish the electro-magnetic fields for the primary, while at the same time the galvanic action needs to be preserved, and the resistance of the iron wire also needs to be considered in relation to maximizing current and minimizing resistive heat losses.

One possibility then might be to establish, by the use of capacitance, an alternating or plused current in the open ended coil wires, thus avoiding shorting out the 'plate cell' pairs. If this could be done then you could wind numerous alternations of copper and iron wire pairs together around the iron core of a single 'battery', which would serve the same function of stacked plates in series in a regular voltaic couple, automatically providing an overall higher 'battery' voltage.

This whole train of thought is probably far from what Stubblefield did and not relevant to the issue, but then the thread is about speculations and I mistakenly thought you might have been discussing a capacitance situation.

PS The oddest thing. Above your post the thread seems to have a different name. You seemed to be addressing me so I returned to you, but I did not use the quote reply method because it appeared to be a new thread???
weird stuff today.

When a comment is left the subject line by default contains the name of the forum topic thread; however, it may be amended, as in emails, to let readers of the topic know at a glance what the comment is about. This can be useful in threads, such as this one, that have many ideas being tossed about at the same time; thanks in no small part to yourself.

can you  explain a little more about how to go about this ?

I have played  with the idea a little  but  havn't got  anyhing to work  so far .

My  goal  for   the " core" part of the  battery is  a couple volts  and  maybe a  hundred  or so m A
AC  would  be ideal ....... DC makes things a bit harder .


One of my reasons  for  trying the Tesla  pancake  type winding  is because if it works  it would make a " modular " stubblefield  cell .........just  build and stack  untill you  reach the right  power  level.

I am  still undecided   about   how well  it works mostly do to the wiring    there  are many  posabilitys  .....  sometimes changing  one wire and the voltage across the whole thing drops almost to nothing .
