How about moving around some ice bergs to areas in need of fresh water?
Dassault was working on "Project Ice Dream" - https://www.youtube.com/watch?v=PL5blnAH9xw https://www.youtube.com/watch?v=PL5blnAH9xw - which centered on tugboats to move ice bergs around... sails would probably work too.
This also doubles as large-scale cargo transportation between continents, for cargo that can tolerate a 6 month journey. An awful lot of cargo can fit on an ice berg with a surface area of many hundreds of square kilometers.....

This was a problem my high school math tutor, a glaciologist discussed with me one evening doing some applied math. cf https://news.ycombinator.com/item?id=12341964 https://news.ycombinator.com/item?id=12341964
- kanzure 10y agoTugboats aren't the only option--- you could use on-shore rope wrangling and pulling, you could use sails, you could use focused orbital mirrors to melt ice on one side as a propulsive force... and so on.
- bootload 10y agoThis idea of pushing, pulling icebergs was investigated by ppl much smarter than me (Glaciology/Maths dept. Uni Melb) to see if it was at least feasible. The idea has some merit, the physics (moments of inertia) get in the way. Make for an interesting experiment to prove how.
