The Eliodomestico is basically a personal desalination still, which operates similar to an “upside down coffee percolator.” The device is an open-source design, noted for its remarkable simplicity to build and use, as specifically intended by Diamanti when creating the solar still. The device consists of two ceramic pieces that sit on top of one another. Within the top piece is a black container into which the salt water is deposited.
