Re: [TCML] Re: Stacked Toroids

You can increase the capacitance indefinitely by increasing the distance 
apart. Provided the spacer is smooth, you won't get any breakout from the 
spacer, only the toroids.
Anything more than a few feet might look silly but here is a pic of my "Red 
Alert" Tesla coil working with 3 spaced toroids and a sphere.
