[TCML] A Novel Approach to Ball Lightning

[bartb <bartb@xxxxxxxxxxxxxxxx>]

Hi All,

I've been messing with a design concept. I basically built a 1/2 scale 
replica of NT's flat coil as many know. As I've looked into primary 
coils for this secondary, there are problems with the standard rim 
grounded scenario (problems deal with coupling, practicality, top load 
sphere or toroid placement, etc..). After enough time of goofing around 
with various configurations, it occurs to me that this particular coil 
would do better with a center grounded configuration.

Here's the secondary:

It appears that if a say 2" toroid is placed around the perimeter of the 
secondary (the secondary fits like a center disc to the toroid in the 
middle), then most of the problems go away. The primary can then suit 
decent turns and various cap values. The center ends up at ground, the 
primary placement can be both on top and bottom on each side of this 
flat coil near the low voltage end. So, that's not too difficult to imagine.

But then I was imagining the entire secondary center to a large sphere 
with the primary and secondary internal to the sphere. Looking something 
like this:

The secondary is horizontal in the center spanning the sphere diameter. 
There is a PVC tube in the middle and a flat primary 5" above and 
another 5" below the secondary.

Ignoring the obvious implications of ROC and ignoring how to pass wires 
into the sphere, I was wondering how the internal coil would react. I 
expect sparks would issue from the sphere to the primary coils 
internally, but then, I started questioning myself.

So I thought I would write the TCML and get your opinions on such a design.

Any comments?

Regards,
Bart
