Una universidad desarrolla desalinización solar sin salmuera tóxica

Investigadores de la Universidad de Rochester han creado un sistema alimentado por energía solar que convierte agua de mar en agua dulce, evitando al mismo tiempo la producción de salmuera líquida nociva. La tecnología utiliza paneles texturizados con láser para evaporar el agua y recolectar las sales como sólidos.

El sistema emplea paneles de metal negro tratados con láseres de femtosegundos para absorber la luz solar y distribuir el agua de mar a través de una superficie activa. A medida que el agua se evapora, las sales son dirigidas hacia regiones pasivas utilizando el efecto de anillo de café, evitando obstrucciones durante la operación. Las pruebas con muestras de los océanos Pacífico, Atlántico e Índico confirmaron la extracción continua de agua dulce y un rendimiento de autolimpieza.
