"skin effect" as i understand it, is related to HZ. a while ago, i came across a link from a link from a Telsa link, where a rather bold individual actually had a pix of himself discharging a bolt of lightning from his pointed finger like Zeus. He claimed that he was unaffected , due to this phenomenon. He also had a do-not-try-this-at-home disclaimer, not that i was at all inspired to.
