does this imply that you could use a fluorescent tube ( a form of a mercury 
arc lamp) as a HV rectifier???  if so, that could prove interesting. Or what 
about one of those mercury vapor street lights??
[bill]  snip
Steinmetz used brush generators to power his street lamps 
with DC.  Ever the electrical engineer and inventor, Steinmetz next 
invented the mercury vapor lamp which he also powered with DC along 
with his magnetite arc lamps and brush generator.  A very strange thing 
occured.  Steinmetz found that when he used both the magnetite arc 
lamps and mercury vapor lamps in series he could power them with 
alternating current.  Steinmetz had unwittingly invented the first 
mercury vacuum rectifier.
