Hey all,

Happy holidays.

I'm working on the next version of WinTesla, and am trying to refine some of 
my equations in the program, and I would like some feedback from those of you 
who take notes when you experiment.

First, I am adding spark gap information, and updating the terminal 
capacitance value.  One factor that hasn't been documented too well as of yet 
is the effects of relative humidity on spark gaps and tuning.  The dielectric 
strength of air changes with humidity, and thus changes the capacitance of 
your top load capacitor and the trigger voltage of your spark gaps.  I know 
that when it's colder and less humid, I have to set my RSG gaps closer, and 
re-tune the primary.  The output of the coil, however, doesn't seem to be 
affected?? 

Second, a value of 8400 volts/inch has been stated as a measure of output 
spark, but doesn't hold for gap settings, since un-ionized air requires 
closer spacing for the same voltage.  This is why (if you have a variable 
spark gap) you have to move the gaps closer to begin a session, but can then 
move them apart while operating to get more output.

I'd be interested in any experiments with humidity and spark gap settings, or 
just observations/oddities in tuning and such.

Thanks in advance,

R. Scott Coppersmith
