I think here is some s$#% stirring going on.

Firstly i don't believe that guy with the fluro tube.
He is not standing near or under those lines, i think the photo is doctorred somehow.

Also during the building of the house you would expect the builders getting shocks already of steel pipes, roofing material etc.

HT power lines have usually easements around them. If people are stupid enough to build to close, or underneath, that is their problem, not the POCO.

The product of rotation, excitation and flux produces electricty.
