If you are at all concerned about EMF you should start by eliminating

Really. Well well. Fascinating what one learns on Usenet these days.

Maybe you can explain to us all how it is that a circuit - ring, star,
or crop-circle ompholotic spiral - in which the currents 'out' and 'back'
pass in opposite directions in conductors sharing the same outer jacket -
gives rise to an Electro-Magnetik Feeled? (Hint: transformers and other
things with Coils use jsut *one* of the con-duck-tours wrapped around
the iron former).

If you're paranoid about electrickle fields, you'd do better to pay
attention to the layout of your *lighting* circuits, in which the
feed & return (that's live and neutral in your planet's English) are
widely separated, as mentioned here in occasional discussions about
interference with hearing-aid inductive pickups. There at least there's
a mechanism to *produce* a detectable em field; how you then go from
'detectable' to 'brain and health scrambling' is another step, which
might meet with a little scepticism. Still, Gallileo was also ridiculed
in his time, wasn't he...
