As global warming becomes an increasing threat, extreme weather conditions will be more prevalent, requiring us to look closely at drought solutions. Mexican chemical engineer Sergio Jesus Rico Velasco spent decades trying to solve this very problem. He created a product called Solid Rain, a powder that turns water into gel.
Inspired by diapers, this absorbent polymer can expand up to 500 times its size and store water for up to one year. It only needs 10 grams to expand into one liter, and is unaffected by evaporation. Additionally, a Mexican study determined farm land yielded 300% more crops using Solid Rain. This is an award-winning product, as it was honored by the Stockhold International Water Institute and the Fundacion Miguel Aleman.
For the past decade, Solid Rain has been used in Mexico. Given that its selling price is only $25 per pound, it is definitely worth looking at seriously as far as drought solutions go.
