Gas pipes are non-metallic I think? 

Not sure I like the idea of connecting many watts of VLF power into high 
voltage pylons or gas pipes. In the UK we would be locked up as suspected 
terrorists!

Having a few watts VLF piggyback a water pipe connected to my central heating 
radiators sounds as if it should be more legitimate. After all,  we use such 
connections often as the ground systems for verticals.

This raises the question about the legality of putting VLF signals along 
utilities - is this actually permitted? After all, there are intercoms and data 
systems that intentionally use the mains electricity wiring. Anyone know what 
IS permitted?
