From the year 2000 water started to be recognized as a fragile resource and the importance to keep it clean and pure was recognized by many. For these reasons, in the 21st century, water will determine new land-use for growing populations, regional political alliances, and alternative energy production. Desalinization is one important aspect of the future of water; it already is a critical social concern, particularly in flood vulnerable and arid affected regions. Focusing on the simple “water cycle” of evaporation – condensation, we can study and enrich our sustainable relationship with alternative water sources, since now we have been overtaken by massive desalinization plants. Redesigning daily life at a local level becomes the way to respond to current environmental realities through our knowledge in environmental and biological design, as well as in in parametric and digital fabrication tools.
The project is thought to be developed for areas hit by natural disaster where access to clean and safe water is an issue. It is programmed to be built by the affected community through the shipped of a commercial container reinvented as Fabrication Lab providing with high standard fabrication tools and internet connection the local population. The aim is to reactivate the local market through professional training, as well as production of primary needs (food and tools).
Recently, a re-examination of existing seawater greenhouse technologies has revealed implementation possibilities for different scales through sustainable desalination using deep seawater and warm sea laminar water in an evaporation-condensation loop.
The project is a landscape greenhouse-canopy characterized by two performative pattern logics. The first is a three dimensional meshwork of capillaries within which cold seawater (from a local deep source) is circulated in loop. The second is a series of vascular flow intake, which direct warm seawater (surface layer) over the capillaries. Contaminated water drips into specific areas, called vacuoles.
The transparent lenses create additional heat in the sub-interior space, through the greenhouse effect, allowing the air to take on even more airborne moisture. Then, when this humidified air comes into contact with the chilled pipes, it condensates.
The condensation drips down the capillaries into pleated troughs below, which lead to seasonal storage tanks.
The water introduced into the circulatory system is returned to the source, for a constant functioning cycle. The solar powered pump will have two different pumping settings: a faster one for the Cold-Water Vascular System and a slower one for the Hot-Water Vascular System.
The desalinated water is collected in storage and conducted through gravity in three directions, according to the needs:
1) Part of the clean water is stored in the appropriate storage vacuoles that connect with the watering system of the greenhouse, as well as to outdoor fountains for community usage, through automatic or manual valves.
2) Most of the clean water is directly injected into the watering dripping system of the greenhouse.
3) A small part of the clean water is stored in test tubes for monthly monitoring of water quality from eventual contamination.
