Subject: Re: VDG/Tesla coil



I presume that you are correct about the skin depth for wet meat, but it
sure surprises me. How could this guy pass enough current that it would
start wood burning, but not be injured? Is there some way that he could
have been conning the video - done something that he didn't tell
about? Do you have any idea how much power the body can actually pass at
these frequencies before you know it immediately? Or how long might
someone last after doing this regularly? Any helpful references?

I always wanted to try this, but I think that I just lost my faith in God.
