The idea has been bandied about for decades: could we tow an iceberg to a place where the contained water could be obtained by melting to help alleviate parched areas of the world? Well, the place I'm thinking of now is California, which would be a long trip for the big tabular bergs from Antarctica that might really make a difference, but I wonder if the bergs spawned by glaciers in Alaska might work.
The current problem in California underscores the need for more and cheaper energy (i.e., nuclear). If you don't think it's cheaper, then you don't realize the problems accruing from not having enough. If we had plenty of generating capacity, we could run desalination plants, which would reduce the demand on reservoirs like Lakes Mead and Powell and Tuolomne that are going lower inch by inch. (Not to mention the groundwater that is getting drained from below California.)
