Re: [TCML] A Safe Tesla Coil - was: Tesladownunder update, briefcase coil, lots of sparks etc



That's a Billion Watts of peak power!! - Awesome!!
But was this an educated guess or did Tesla measure this current? and what with? I guess he could have used a compass that was nearby and then extrapolated maybe?

The sparks from a big TC are not really in the range of mA, however the waveform is chaotic and have peak current potentially in 10's of amps on a microsecond basis. Even my small TC will give muscular contraction so it must be haveing a physiological effect. So the real safety answers? Primaries are potentialy lethal and secondaries may be.

I agree entirely. All the bad info out there saying tesla coil outputs are
'safe' as the high freqencies cannot 'be felt', is terribly misleading. The energy availible in a signal tesla 'strike' is probably quite considerable,
certainly enough to do damage, even if you can't feel it immediately (from
my experience you can always feel it anyway).

Terry, as you are a doctor you could probably answer this question; what is the exact machanism by which electrocution causes death? Im aware there are
usually more than one reasons, but what are the most common? In terms of
disrupting the nerves in you heart/circulatory system, it would be
interesting to know if the higher rf freqeuncies can actually cause the same
effects as DC and lower audio frequencies. If not, maybe the output is
'safer' than its made out to be (bad wording, really should be 'not as much of a risk'). Aside from these effects there would be the usual burning etc,
which seem to be worse at radio frequencies, but still for a small coil
probably not life threatening.
