Re: SSTC does 10 foot sparks

Good question, how do we measure the input/output power?  I dont know 
myself and wasnt sure it really even mattered, aside from being reasonably 
close and honest with my guesses.  Someone wanna seal up a TC in a big 
styrofoam container and see how much heat we create? hehehe.  Seriously, i 
cant myself afford such measuring equipment other than some cheap ammeters 
and a small wattmeter (that is too little for this coil).  What i *can* do 
is use previous knowledge gained from my first prototype and others work to 
make good guesses at things like how much power im using and what efficiency.
The other thing i can rely on is simulation results from pspice.

The way i see it is, i havent blown the 20A fuse yet and ive had several 
long runs so far (telling me it likely isnt pulling more than 20A).  Other 
thing is that my coil slightly beats Freau's spark length formula... well 
this makes perfect sense, no gap losses (and i will tell you, my power 
components arent wasting much at all, they run cold to the touch).

So i guess whats most important to me (and likely many others) is that you 
can get 11 foot sparks (i hit 11'4" the other night) on a 20A 240V line 
without popping breakers and without a pig.
