built any coils for 5 years and am trying to catch on to this cult like
awareness of the physics involved with tesla coils. I am entirely lacking in
this knowlege but wish to learn. I expected the objection of melt down but
who is to say that this can not function similar to oil filled caps. This
proposition is pretty "out there" and I just wondered if any one had thought
it practical. In as much as I dont quite understand the term lossy( does it
mean greater heat manifestation in the cap?) ; I will take your suggestion
that a wax concentrate is inpractical . Thanx HDN
