A different solar desalinator ?...

[Externet]

Hi all ! and thanks for the replies to the related preamble post "Metal under the hot sun" found here:

Let's imagine...

 

Metal pipe(s), say 10cm ⌀, vertical, blackened, say 3metres long, vents at the bottom, exposed to sun heat.

 

A nozzle misting seawater inside from their tops. Flow calibrated to always have a little brine draining at the bottom. A shaded wind cooled condenser at the top of the pipe(s) to collect evaporated water.

 

There is room for some improvements as transferring the condensed water warmth to the incoming cool seawater with a exchanger, etc. but let's ignore those. There is a need to care for simplicity and cost.

There is much more to ideas, there is calculations. Where do I start to speculate about productivity ?
