Water scarcity is one of the most pressing issues of our time. At the point 6 of the United Nation’s 17 Sustainable Development Goals (SDG) we read: “Ensure access to water and sanitation for all”. The question is if it possible to satisfy this need for millions in the upcoming 5 to 20 years, and with a carbon-neutral process.
Cosimo Scotucci envisions dH20me, a scalable solution that consists of a greenhouse in the ocean. Thanks to the solar radiation, the water inside of the dome evaporates, separating itself from salt and other products contained in it, to condense eventually on the glass surface above. the condensed water drops on the surface are perfectly fresh and through only gravity will slide down into the draining system which runs all along the perimeter. Once collected there the water can be extracted directly or channelled into pipelines. Salt and bi-products then could be sold, generating money and supporting new economies’ development.
