Hi Ken,

I noticed that in your latest drawing your slip rings are now 
continuos.  Does this mean that you've abandoned the idea of reversing the 
polarity of the charging voltage every 180 degrees of rotation?  I never 
completely understood the rational for this reversal and I can see where 
doing away with this requirement certainly simplifies the design while also 
resolving the question of what happens to the energy in the caps should the 
discharge gap fail to arc.
