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.
