Apart from farming, it can also be used to reduce the amount of watering need for lawns, gardens, flowers and countless other home-based plants.
Solid Rain is a Mexican-made product that looks like salt and sells for $25 a pound. It’s makers claim that the product is capable of solving the world’s drought problems.
The product’s creator is a chemical engineer by the name of Sergio Jésus Rico Velasco, a man who’s spent decades trying to mitigate the drought problems that Mexico suffers from.
Inspired by baby diapers – Solid Rain is actually a highly absorbent polymer called potassium polyacrylate, which soaks in water up to 500 times its original size. 10 grams is all it takes to soak up a litre of water, transforming it into a thick, translucent gel.
The water can stay in this state for up to a year, not being effected by evaporation or having any other way to escape except when it is consumed by a plant’s roots.
A study by the Mexican government showed that farm plots yielded 300 percent more crops when Solid Rain was used. Three examples include oatmeal, which yielded 5000 kg per hectare with Solid Rain, versus 2500 kg per hectare without, sunflowers . 3000kg with versus 1000kg without, and bean which yielded a staggering 3000kg with versus 450kg without.
