The sun heats the container of water, turning the water into steam. The pressure then builds until the steam is forced into a tube and is deposited into a container, where the water then cools, condenses and collects in the basin.
The Eliodomestico is designed to be carried upon the head when traveling, as is common place in developing countries where water is not a centralized commodity. People often are forced to walk great distances to collect this vital resource.
The solar still has the ability to collect about five liters of water a day and costs less than $50 to build. This simple, yet effective, lifesaving device has the potential to permanently change the lives of millions of people across the globe.
