Actually, I was just about to say, why would any suposedly natural phenomenon occur in straight lines anyway? I mean if there really are "Earth Energies", surely they would be the product of geological features such as fissures, fault-lines, tectonic stress-lines, etc. Even if they were the product of some other process, geological features would tend to distort them into non-linear patterns. You only have to look at a geological map of the UK to realise that there's quite a mix of stuff under our feet and very few straight lines amongst it all (except perhaps the Caledonian canal).
I also don't understand how anyone can "dowse" or otherwise detect lines that run over such vast distances. My own experience of dowsing is that there are lots of "detectable" phenomena wherever you look, so who is to say that such lines are actually continuous over the whole of their length. Perhaps they are just a series of disconnected features that someone found because they were looking for them along a line that they supposed to be there.
It's a bit like drawing a line across a large city and then saying that wherever you look there is a building and (wonder of wonders) they all line up!
