Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

@ Mk1

Being new in this forum I did not realise that you are the original creator of the stubby Stubblefield coil Lidmotor shows in his latest video.

You propably said it somewhere in these threads, nevertheless I take the liberty to ask some questions:

- Did you insulate the core (with cotton or a sticky tape)? The core should be black iron (soft if possible, but steal seems to work too)? What about using a bunch of galvanised iron wire sticks as a core, binding them together tightly with some tape to form a rod?

- Dimesions and material of the wires? Which cotton covered wire did you use? I guess one has to use galvanised iron wire? What about thin wire, would not that be easier to wind tightly?

- Some people talk about using aluminium wire instead of the iron wire? What is your opinion, is galvanised iron better?

Greetings, Conrad

Sorry Conrad , my part is at the very end of the video , when he said that someone mentioned that the coil went down because of the missing pressure , Most of us even me at first failed to recognize how important the bolt is to a functional coil ...

I am only responsible of seeing how perfect NS design was.

Cotton or silk should be used on the core but other materiel's like mica could be tried. The core should be at least soft iron with a low carbon content. High iron,low carbon with silicone is better. Plain steel that has a high carbon content can become permanently magnetized,hindering the field collapse as some here can attest to. Aluminum has a much lower galvanic current and magnetic field collapse than iron,but could be used for lower voltages and current to run a jewel thief or other device. So far there are problems with galvanized wire. Ns didnt have galvanized wire back then. Thinner wire would require more turns for more power,so it depends on how much power you want. The wires dont have to be the exact same size but you dont want a large difference.  It would seem that a high iron, low carbon core and plain iron wire with low carbon would be ideal. Finding a core is easy, but a high iron low carbon wire is not. Plain steel wire would probably not work well because of the magnetization . 
Its getting old I know but Ill say it again. Location of the coil was a prime priority with Stubblefield.

Can you elaborate on this? I think I may have missed some posts describing the issues.
Thanks

Lidmotor,dragon and others are reporting there coils last only for a day or two. Lidmotor found his zinc coating ate up after only one day.
