The Ing. Sergio Jesús Rico Velasco created a new technology that makes a huge impact in the way we are using water for food production.

Velasco later realised that his potassium-based polymer could be used as a way to cure Mexico’s drought problems.

Solid Rain is an absorbent polymer called potassium polyacrylate.
This polymer is capable of soaking in water up to 500 times its original size.
A whole litre of water can be absorbed in just 10 grams of Solid Rain, which then converts into a thick, translucent gel.
The liquid retained in this gel will stay there for a year without evaporating or seeping out.

Solid Rain sells for around £17 ($25) per pound.

According to magazine Modern Farmer, the Mexican government conducted a one-season sample study on farmers using Solid Rain in the semi-arid state of Hidalgo.
Farm plots showed up to 300 per cent increases in crop yield when Solid Rain was used.

Solid Rain recently won the Ecology and Environment award from the Fundacion Miguel Aleman, and it’s been used in Mexico for a decade. However, Velasco didn’t market it heavily and it only went one on sale in the U.S last year.
