 Hi Jeff,
 I hope you'll read this.
 THE LIGHTNING GUY EXPERIMENTS.
 I have been waitin for a long time someone to mention

 these Turner's experiments.On his home page picture 

http://ourworld-dot-compuserve-dot-com/homepages/bturner/brent_4jpg

  he emphasizes he doesn't recommand anybody to
conduct the experiment.Now,if we assume that
everything is secured (ie. there's no chance that
spark attaches any part of  primary circuit ,or power
transformer circuit or the outlet 110 V in the
neighbour wall perhaps) what could be dangerous about
such experiment? 
My instant answer is that large isotropic capacity of
his body presents great danger.I'll elaborate
this.Discharge currents directly from his body as
terminal (lasting for microsecond or so) have very
high peaks and DC component which is always cause for
the shock.UMHO situation may be similar to that when
coiler receive horrible shock from ~ 50 pf top
isotropic capacity coil.(Few guys have actually
measured wave forms and happennings during ground
strikes from their systems).Now ,why Brent didn't
receive shock?My  answer is becouse of the SPECIAL
SAFETY HARNESS he wore and only becouse of that.I
suppose it had metalic fibres in it and solid
discharge  currents passed mostly through it instead
through his body (something like Faraday cage
effect).What bothers me is that at 
  http://www.teslacoil-dot-com/html/images.htm
 I'm not sure if he is wearing that harness (surely
current waveform pased his hand tissue) and left arc
doesn't seem to be of corona kind (tends to attach to
conducting wall).Will you tell us more about settings
on that photo and lightning guy experiments in
general.
Thanks in advance.

Regards,
Boris
 P.S I have emailed Brent few times but haven't
received reply yet
