Sergio Rico invents “solid rainwater” through a process that could revolutionize agriculture. This consists of optimizing the use of rainwater. “By working on the recovery of rainwater, we have found a way to solidify it to give it another value. I was inspired by baby diapers that allow you to absorb liquid in a minimum of space. And, it is from there that I had the idea of transforming rainwater by keeping it in molecular form in a very absorbent acrylate whose characteristic is to store up to 500 times its weight in water without changing its chemical structure,” says Sergio Rico.
Rainwater, collected from the roofs, is channeled to a tank in which it is sufficient to pour a dose of 1,5 grams of potassium polyacrylate for 1 liter of water. In 15 minutes, we witness the process of water solidification. Ionization and precipitation then occur which allow water molecules to stick to polymers, resulting in water in grains, in the solid state. With this process, there is no need for pumps, pipes, electric power, tankers to transport the liquid. Solidified water can be put in plastic bags that can be easily stored until needed.
