Is This "E-Power" Machine Dangeorus?
70 KHz will only travel a few mm deep. Lool into the skin effect, high freqency power likes to stay on surfaces. While I can not image this having any health benifits, as someone the works with Tesla coils a lot, it should not be to dangerous. I have had 100s of Watts of power across my body at ~150kHz and I'm still here.
