Pesquisadores da Universidade do Texas em Austin, desenvolveram um filme de gel de baixo custo, que pode absorver água da atmosfera.

O gel pode extrair até dois litros de água potável por dia, mesmo em regiões muito secas, como um deserto.

Um único quilo desse gel foi capaz de coletar mais de 6 litros de água por dia, mesmo em ar árido.

Segundo a OMS, cerca de um terço da população mundial não tem acesso a água potável, e esse número só deve aumentar devido a dois fatores:

Expansão populacional e mudanças climáticas. É por isso que muitos cientistas trabalham duro para criar novas tecnologias para evitar um futuro mais sedento.

O novo filme de gel desenvolvido pelos cientistas tem como base a celulose, o principal ingrediente presente nas paredes celulares das plantas que ajuda a planta a ficar rígida e resistente.

Além disso, o gel ainda tem goma, uma fibra dietética natural solúvel em água produzida a partir das raízes do inhame e frequentemente usada como alimento.

O funcionamento é simples, a natureza porosa da goma atrai e retém as moléculas de água.

Após o gel ser aquecido, a celulose torna-se repelente à água, permitindo que a água retida no gel escape.
