Trivia: Most of the Municipal water supply in Boulder, CO is "harvested" from the Arapahoe Glacier on Long's Peak --including the remains of dead elk, Clark's Nuthatches, hikers, and crashed airplanes.
But that's not what you wanted to know.
Costs of towing chunks to be used in the arid west would be a lot, let alone getting the water back up to the land for distribution.
Although, come to think of it, it might eliminate the costs of all the water litigation that goes on in these areas. Water lawyers and Water Courts beware! Your rice bowl may be broken if we did that!
I like the idea of towing them to he coast of Somalia, though... sort of, in a darkly humorous way.
And sooner or later, someone will bring up the story of that ship fabricated from ice and sawdust, so I might as well right now.
