Technology doesn’t always have to be complicated, sometimes the simplest materials and concepts are the best. The Eliodomestico works like an upside-down coffee percolator to desalinate salt water. The ceramic oven has three main pieces. The top black container is where the salt water is poured. As the sun heats the salt water and creates steam, the pressure that builds pushes the steam through a pipe in the middle section. The steam condenses against the lid of the basin at the bottom and then drips into the basin, where it is collected.
The oven can make about five liters of fresh water a day.
