Vertical Farm in Dubai Uses Seawater

A good rendering is a thing of beauty, and when it is of an amazing vertical farm, so much the better. Italian architects Studiomobile has developed a Seawater vertical farm to be built in Dubai.

"The seawater vertical farm uses seawater to cool and humidify greenhouses and to
convert sufficient humidity back in to fresh water to irrigate the crops."

It is designed to work with seawater:

phase 01

The air going into the greenhouse is first cooled and humidified by seawater, which is trickled over the first evaporator. this provides a fresh and humid climate for the crops that in these conditions need very little water as they are not stressed by excessive transpiration.

phase 02

As the air leaves the growing area it passes through the second evaporator which has seawater flowing over it. during this phase the humid air mix with the warm dry air of the ceiling interspace. thus the air is made much hotter and more humid.

phase 03

The warm air is forced to flow upward by the stack effect that is temperature induced. in the central chimney the warm and humid air will condense when in contact with plastic tubes where cool sea water is pumped. in the surface of the condenser many drops of fresh water will appear, ready to be recollected in a tank to water the crops and for other uses.
