I was just curious, I hear the skin effect in human beings still very deep
at standard Tesla coil frequencies, does anyone here have references or
sources as to where the information is gathered about how deep currents
penetrate into the human bodies at different frequencies?
Thanks,
Adam

Hi Adam,
     I do not have specific references handy, but please consider this: The 
so-called "skin effect" is usually measured for homogenous, nonreactive 
substances. The human body is not a homogenous substance like a copper or 
aluminum wire or a bar of brass, but is made up of hundreds of different 
structures and tissue types. As such, the "skin effect" does not just apply 
to human skin (dermis) but one must also consider the effects on, and 
response of, each type of tissue.(Leg bones may respond very differently to 
HF voltages than eyeballs.)  HF skin effect on a fluid (blood) may be very 
different from the effects on a solid, and nerve tissue (neurons) have 
surfaces covered with reactive electrical dipoles, which may respond very 
differently than a passive piece of brass. Even measurements made on a 
cadaver may not tell the whole story of effects on a living organism. I 
believe (but I may be wrong) that most of the current data is from 
laboratory animal tests and "accidental" subjects. Extrapolating from mouse 
to man is always a little iffy, and long-term effects are hard to measure 
quickly (DUH) ;^)))) While a bikini-clad  "tomato" on a TC might be fun to 
watch, if by age 60 she's a neurological "kumquat", few people will take 
notice.
     Tesla's own work on this and even x-ray exposure, involved only 
himself as subject. (not recommended!) Most notes on "work" done by Drs. 
Mengele et.al. were either destroyed or classified for government use by 
OSS/CIA.
