New developments in Tesla Coils
As a Card-Carrying Geek, I am fascinated by Tesla Coils.
There has been a very interesting development in the last year or so with the advent of cheap, fast and high-power semiconductors. People are eliminating the high voltage circuitry, the expensive capacitors and the lossy spark gaps (over 50% of the input energy is lost in the spark gap of a traditional coil) and they are going with solid state drivers running at a few hundred Volts at high current (several hundred Amperes).
Here is a coil that is 12" tall running at 700 Amps with streamers running out to 48" -- four times the height of the coil.

Here is the book.
