Taking into accounts the dimensions of Tesla's lab, photos, etc., it 
appears the longest arcs Tesla achieved were about 32 feet.  Tesla 
"speculated" on far greater distances that were "reported" as fact on many 
occasions, but it was really about 32 feet.

It was a wild place ;-))

I would not take technical quotes from "Problem of Increasing human energy" 
to seriously...  "Actual path" has a lot of twisted meanings...  Bill 
Wysock's coil can hit a target a solid 59 feet distant...

No.  Streamers make ionized high conductivity trails.  They act like wires 
for most of the distance.  If Tesla had a 153nF primary cap charged to 
50kV, in order to make 13.3MV the terminal capacitance would have to 
be  SQRT(50/13300) x 153e-9 = 9.3 pF...  Not possible...  Long streamer 
need extreme power, not extreme voltage...

In the years following Colorado Springs, Tesla gave a lot of interviews 
that were "translated" in many funny ways by folks that had no idea what he 
was talking about...  Best to rely on direct quotes or secondary 
information form technical people...

Cheers,
