I did some testing of the low frequency idea, but I didn't see much 
improvement...I had hoped I would have seen an improvement since
skin effect and radiation losses are lower at lower freq.  Still, I like the
idea of low frequency operation.  There might not be too much 
difference between 100kHz and 250kHz, but if you go high enough, like
800kHz, the spark will probably weaken and start to take on a flame-
like appearance.
