Hi Steve,

In a nutshell...
Voltage is about 2MV, energy is a few thousand joules, and you have 
to maintain the drive for about 1mS.*

DRSSTC's make the last two easy "now" ;-))

Basically you get the leader going and keep feeding it with power to 
keep the channel heated and supply the tip with voltage and energy so 
it can keep going and going and going...

The 2MV and 1000's of joules is sort of hard right now, but we can 
certainly work on a little less than 450 feet version. ;-))  I think 
the coil has to be lower impedance to maintain the high voltage 
transfer longer too...

Cheers,

        Terry

*Gerry has the book, but I think those are the numbers?
