Richard,

If you want to see just how this charging works, just hook a nice fat 
.1UFd -30KV cap between ground and those stacked toroids on the milk 
crates.

The impedance of the system is low enough to charge a big ole healthy cap 
and when shorted... BOOM!  So this is not some high impedance whimpy DC 
charging mechanism, but can supply power if needed.  This is also too 
easy not to try.  I have been running lots of Electrostatic machines of 
of the collectors, too.  All from a coil of 15-20 watts.

Good work, nice to here someone else monkeyed around with this a bit.  I 
am about to undertake a series of quantitative experiments in this 
matter.  More as I figure it out.
