Zero Energy Desalination Plant and Theater


A new "Water Theater" is being planned for the Canary Islands which will not only be a seaside cultural center for performing arts, but will also serve as an innovative desalination plant. The architecture of the sea-facing wall is such that cool sea water is pumped into tubes then sprayed on a membrane through which sun-warmed air flows. The warm air over the cooler tubes causes the condensation of fresh water which drips into collecting troughs below. This is essentially a giant solar convection powered dehumidifier that supposedly can provide enough fresh water for an entire city! It also combines aesthetic architecture with renewable resource management and doubles as a theater that benefits the entire community. I'm curious to see what a dehumidifier of this size does to the local weather patterns, though.

Shouldn't be titled desalination then. Will only work if dew point is higher than cooling water temperature.

Picky, picky, picky.

It's not zero energy if water has to be pumped through it.
