Needless to say the trencher was an ebay purchase - I've 700 metres of water pipe to bury - it's on the surface at the moment feeding stock troughs and not only is in danger of freezing, but looks unsightly and it's easy to catch it with tractor implements.

That's interesting, I thought a GSHP needed to be much deeper than that. I'm considering one for a future project, what system are you looking at?

I believe the 18" is just for the electric cable. I understand Andrew is considering getting the source from somewhere on the Nullabor Plain!

That's the beauty of the plan - red blood over green paint would absorb pretty much all of the light falling on it, so you'd see a dark streak and wonder what it was!
A CB rig doctor I knew once upon a time was red/green colour blind, which made identifying electronic components by their colour codes pretty tricky - he had a pair of glasses made with one red, one green lens (like 3-D glasses, really), by closing each eye in turn he could work out whether a colour was reddish or greenish :o)

I'm not as bad as that. When I first started dabbling in radio and electronics, the resistors were large enough for me to read the value bands. Now they have got so tiny, I have to get my magnifying glass out so my eye gets as much colour information as possible. When I look at a strand of sewing cotton, I can't tell much more than if it is light or dark. Give me the real of cotton and I am fine.
