I have just had another thought,
if we had a load of straight rivery type channels or that type of thing, we could put the main industry right along side the banks of them and transport the goods by boat and they could even be pulled by horses, no bad gasses except the odd fart----- but---I suppose that would never catch on I dont think
.
A lot of Britain's main fibre optic Internet backbones run along old canal towpaths. Straight lines - no traffic and unlikely to be dug up by the gas board!
