The Lluvia del Cardenal is a portable, detachable rainwater collector designed for communities facing water scarcity and limited infrastructure. Its conical and rotating design, guided by a wind vane, maximizes capture efficiency (44L capacity total) without needing a roof. It uses recycled and recyclable materials (RPET fabric, PLA, polypropylene) for a closed resource loop, providing non-potable water for domestic uses like cleaning.
