I have heard stories about people living near BBC broadcasting stations putting up big aerials in their loft and getting free power. I think there was even someone prosecuted for stealing electricity or something similar.I guess the advantage of a resonant circuit picking up e-m energy from the air would be that the components are basically just wire and possibly a capacitor or two which are very cheap. I guess the problem with picking it up under power lines would be that you would actually have to be very close as the field will drop off quickly.
Put the two stories together...The last prosecution for this sort of thing was, I believe, someone who had a garden shed under a 400kV transmission line and had it lit for free by flourescent tubes! What you're actually doing is 'stealing' reactive power (VARs) from the grid - there is a loss of power from the lines (though admittedly very small).
Yes you are effectively building a transformer.
Effectively increasing its resistance, and therefore the energy losses.
