Passive Harvesting Water From Air is Now Easier Than Ever

Water scarcity should be a thing of the past

Unfortunately…

About 2 billion people in the world today face water scarcity. While rainwater harvesting (and purification) would work for half of those people, if they could afford the initial investment in a rain harvesting system, the rest live in arid or semi-arid regions where it would not work.

Fortunately…

Now it is possible for those 1 billion people to harvest water from the air, using Atmospheric Water Generators (AWG). You might think that arid regions wouldn’t have enough moisture for harvesting, but in the early morning, relative humidity )RH) can reach 50%, and AWGs only require 30% minimum RH. While most of these AWGs require a lot of electric power, Source Hydropanels only need the energy of the sun.

Unfortunately …

Source Hydropanels cost $3k per 1-3L per day (people say you usually get 1L), and the company just sucks in every way imaginable, according to customers. As far as I know, they have no real competition at the moment.

Fortunately…

The good news is you can DIY this system yourself fairly easily and 5x cheaper than paying Source to do a crappy job at it. All you need is: glass, covering a graphite-painted, magnesium chloride-impregnated cellulose sponge.

Initial cost for the DIY system outlined below is about the same as initial cost for a rainwater harvesting system (starting at $2k for 20L/daily), although after 10 years of rainwater collection the cost per liter is only 2 cents, vs 10 cents for the moisture harvesting system.

One nice thing about the moisture harvesting system is that it doesn’t require purification, because moisture is already pure H2O, while rain drops actually form around nucleation particles of dust or pollution.
