water collection idea

Make water condense on chilled bottles with coils of chilled tubing wrapped around for maximal surface area.

Somehow, I will have to find a way to get those coils to stay in place.  Superglue, perhaps?  For the bottles, use bottled water containers.  For coils, use plastic tubing.  Glue them together and then freeze them.  Use anti freeze to get colder temperatures without freezing.  The colder it is, the better.  Has to stay below dew point before water will condense.  If it stays below freezing for hours, plenty of water should condense.

Additional possibility would be to place many such bottles on racks inside of a metal box.  The bottles will exchange heat with the racks and the walls of the metal box.  More surface area is obtained that way.

With my water experiments, I was able to gather some water this water from the humidifier. There will not be quite so much moisture in the atmosphere, though.

I can also use this cold box to set up another heat exchanger that will take the water through the radiator type device in order to make use of the colder air.  It will double as an air conditioner.

Update:

It may be a good idea to use metal screen in some fashion.  Seems to have a lot of surface area and would conduct heat well for the condensation desired.

This post will go into the water subseries of the off-the-grid main series of posts.
