Waterproof Sand Could Green the Deserts

Waterproof Sand Could Green the Deserts: "By simply laying down a 10-centimetre blanket of DIME Hydrophobic Materials sand beneath typical desert topsoils, the new super sand stops water below the roots level of the plants and maintains a water table, giving greenery a constant water supply. 3000 tons/day is already being produced. 1 ton of silicate coated sand would probably be good for 10 square meters. 4 days of production to cover one square kilometer. More factories will be needed made to scale this up to address the water crisis in the Middle East, Africa, India and China."
