Water is heavy, and almost none of the water used in the world is used for human consumption. It will never make more economic sense to ship water long distances than to move the economic activities that require it to the source of the water. This is leaving aside the subject of aqueducts, but there's really only so long you can make an aqueduct, and most countries border countries in roughly similar economic situations. Siphoning water from "poorer countries" via aqueducts is not going to be a thing.
- thaumasiotes 8y ago> there's really only so long you can make an aqueduct This doesn't make any sense. Oil pipelines cross continents.
- F_r_k 8y agoGood luck watering your fields with a 1m diam pipeline...
- dTal 8y agoOr, to expand on this, a gallon of oil makes a car go dozens of miles, while a gallon of water won't even flush a toilet; volumetrically, the US uses about 50 times as much water as oil.
- thaumasiotes 8y agoI would suggest two 1m diameter pipelines, but I feel like one 1.4m diameter pipeline would be even cheaper. There's no limit on how long you can make an aqueduct. We don't have long aqueducts because water isn't very valuable.
