Re: [TCML] How about some Tesla Coiling?

Hi Jeff, all,

I wonder if the 30 watts vs  6" sparks claim was based
on actual wall plug power draw or was based on the
total energy of primary C (in J or watt/sec) discharge
per bang x BPS, or possibly even just the energy per
bang? I, for one, would be highly suspect of a 6"
or 12" discharge claim from a mere 30 or 35 watts of
actual wall plug power consumption. Am I being overly
pessimistic?

   Where is the description of the power and spark length in Tesla's 
own words?  Is it just possible [some will call this blasphemy] that he 
may have exaggerated things just a bit?

   Somewhere in Hotstreamer there are some pictures of my 
Quadrac-driven spark coil using a pair of GMHEI ignition transformers in 
oil.  With 36 watts input [300 volts at  120 ma] it will give 5" sparks 
although that's limited by the breakdown of the coils rather than the 
available spark length.  Same coil driven from a 12 volt battery through 
a rather inefficient 12 volt to 300 volt DC/DC converter takes 5 amps 
for the same output.  I don't know whether a vibrator interruptor 
excited coil can do as well as a capacitor discharge 
one.................................
