free desert water

Wet the dry lands

There is loads of moisture in the desert air!  If you are travelling in the desert, the of a metal can outsider night under the dust flap of your tent.

And in the morning, the colder the night will have condensed out your morning drink.  Standard life saving technology for the 1950s.

So we use my old friend or a Carnot heat pump.  We pressurise a pure gas and lose their heat to the air 10 feet off the ground.  Where nothing lives.

We drive a captive wind turbine, which is driven by the rising hot air.  That supplies the power for the system.  Probably within a surplus power to drive a light and an electric store - I'm guessing here!  A light for sure.

Then we vent the gas through a ceramic venturing nozzle.  Which will get hot!  Based around him an insultating material.  The gas itself gets really really cold!  We are talking again going from 100° C, to -20!  It's kills according to the absolute pressure.

1 (T₁+273)xP=T₂-273 so if we double the pressure, the temperature swings by 250° C.  We have created the nursing cold of night during the blazing sun!

And water falls out.  Into our collecting jup.  The can use to get 2 pints during the heat of the day.

We have had 10 times the figure unit, and condensate 20 pints of liquid water into a hollow - which becomes a pond.  Wetting and cooling the immediate area.

There is no shortage of water in the days the air, to sir so or two too cold to condense it out.  Ever neither does the air can it get to below 0° C.  Then everything gets a dusting off moisture.
