Hi,

Seen several references, but can't recall where.

Frequently referred to as a 'Bipolar' Tesla Coil, with the secondary
mounted horizontally & the primary generally a helix around the centre
of it.  Then you can put toroids, spheres, whatever on each end of the
secondary.

Try a Google, or Pupman archive search for "bipolar tesla coil" and
you'll find things like this funny double conical one :-

or this little one:-

Probably you'll find bigger ones if you look harder than I did.

Cheers,

Phil Chalk.

Hi -

I would like to wire the secondary
   with toroids on each end,
   rather than a single toroid on top
   and the other side grounded.

My goal is not for sparks or arcs,
   but rather to use the output
   for other purposes, so I will
   be running a bit different tham
   standard 'breakout' design.

I haven't seen this done,
   but I assume someone else has
   already done this somewhere,
   I simply can't find any references.

Anyone here know where to find
   documents referring to a
   'floated ground secondary'?

thanks,
