I keep on with my little project concerning very low cost power distribution.

I think some simple overhead cable is the best distribution to each house. Bare wires seem rather unsafe and are exposed to theft of electricity.

The cheapeast type of cable I can think if would be something similar to an American zip-cord with alumin(i)um conductors. Has anyone seen something like #14 or 2.5 mm2 Al for outdoor use? I can't find anything on the net.

(Someone is likely to bring up the possible fire hazard: I think that can be avoided by using stranded wires, suitable terminations and a trained workforce. The wiring inside the house will still have to be Cu, of course.)
