Eliodomestico

The project intends to bring drinking water to developing countries, at no extra cost.

It works like an upside-down coffee maker. During the day the heat of the sun heats the black watertight boiler, creating steam. The steam is forced down through an expansion nozzle, into a lower basin. The Eliodomestico delivers 5 liters of fresh drinking water a day.
