Hi,
Of course...  However, a reference was also made to "RF burns", and this
does imply something different than the use of a conductive suit, since if a
protective suit was used properly RF burns would not occur. Hard to call
them RF burns as well. High frequency A.C. is more appropriate. The
frequencies I refered to were very low..around 278KHZ.
If one refers to the old Tesla references (which I'm sure most everyone
knows about), there are demonstrations included lighting an incandescant
bulb held in the hand of a brave subject from the discharge itself. I
definitely do not recommend this.

Small coils however operate at much higher frequencies..."real R.F". I still
wouldn't try it.

Thanks

No.  The RF currents ARE NOT passing through this guy's body.  He is wearing
a conductive suit over his entire body including his hands.  This allows the
conductive
suit to act as a faraday cage (sort of) and allow the current to pass from
the topload of the tesla coil, through the conductive suit, and discharge
from the guys fingers
which are also conductive.  No RF current is passing through the guy's body.

This is similar to what Jeff Parisse is doing at KVA Effects in California.
The link below is there great demonstration video showing huge tesla coils,
and many individuals doing the lightning from the
finger trick including one of the female members of GWAR.  (Big video
though - 55MB)

If this guy IS NOT wearing a conductive suit, then yes, he IS slowly
toasting himself to an early grave.

Also, do not get any ideas from either of these videos.  This experiment is
extremely dangerous and performed by trained professional stuntmen.
To attempt this at home would surely win  you a Darwin Award for the year.
