You must have a conductive personality :laugh: *ba dum*
Ok, awful joke, i dunno if this is feasible for your problem or not, but couldnt you just have somthing running outside the building? Rather than an internal grounding wire, an external one like those things that go down the sides of buildings here in britain, they lead to lightning rods here, but yours wouldnt be attached to a lightning rod, it would simply be attached to your apartments electrical system. It could be covered by plastic or rubber or somthing so that nothing bad an happen to it and blow out your whole apartment. Ykno if lightning hit the thing, or some guy witha a tazer came along and shocked it or w/e.
Anyways thats an interesting problem... i went round my house touching things to try and get zapped... no luck though
