Evaporation and Extreme Vacuum

Later this year, I hope to start testing extreme vacuum as a means of desalination. I have found that there is little to none when it comes to water evaporation under vacuum.

With places like those around the Gulf of Suez/Red Sea, with water surface temperature as warm as 30° C., only 28.67 inches of mercury while at 22° C., 29.12 inches of mercury allow for evaporation. What I will be studying is if the rate of cooling is what determines the rate of evaporation.

What I am hoping to find is that water does not actually evaporates but is moved by the excitation of excited (expanded) gasses. If so, then the rate of cooling may determine flow rate. This would be because the gasses having less quantum momentum could not suspend water due to it's mass.

As such, if water is cooled because it is in a shaded area (trees provide shade as well as absorb solar/background radiation), then the cooling as well as the heating of the water would require little energy added to such a system.

The area of extreme vacuum would most likely require the use of stainless steel piping. And when water is not exposed to vacuum, standard pvc pipe (http://davidlasnier.com/wp-content/uploads/2010/10/pvc-pipe.jpghttp://davidlasnier.com/wp-content/uploads/2010/10/pvc-pipe.jpg) should be sufficient.
