@ steve
could we say this is a example of teslas work? he is picking up the radiant waves from the hv lines.. is there a different appoach for broadcasting the same field he is sitting under rather then the linear parellel power lines? like tesla tower design?
I am sorry buddy. I was just joking..I really do not know this man.
But i agree with haithar on this. 50Hz is what is used in european countrys for the grid. Like you have 60Hz.
If you build an antenne which is tuned to 50Hz, then you can pickup that energy. Just the old schole crystal radio circuit, that doesnt have a battery or other powersupply...
