Nanosand could make deserts green: mitigate water scarcity, poverty and water wars
Waterproof sand is being placed into plastic sheets and then buried under the topsoil to create an artificial water table and reduce water losses in irrigation by 75%. 85% of middle east and North Africa water is used for irrigation. 3000 tons/day of nanosand already. 1 ton of sand would probably cover 10 square meters. 4 days to cover a square kilometer. First use of nanotech to start solving a major world problem.
