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. So the sand is inside polyethylene sheets like this roll of fiberglass insulation. The waterproof sand is the filler. Some people are concerned about plastic being used on such a large scale or the environmental effect of the plastic. Yet they are also concerned that plastic will sit in landfills forever. They can select a plastic that will not decompose. This is rolls of plastic with waterproof sand buried under the topsoil to create an artificial water table. This is the first use of nanotechnology to make a major impact on a major problem. Ironically it is similar to the first product that claimed […]
