We are facing difficult weather conditions in the southern Peloponnese this year. Mostly because it hasn't rained properly since March. Now the first winter storms already started, and the wind is ripping through a very dry landscape and vegetation.

Since we are living off grid we feel the environmental changes immediately. One of our natural springs closeby we rely on for water supply has already run dry for this year, making things a little tough. It makes us ponder and look for alternatives.

There are some promising developments in the area of generating water from humidity in the air. But they are still costly for individual use and require quite some energy input.

So, I was surprised to find this little device here - 'Quenchsea'. It can turn sea water to fresh water through reverse osmosis, just by your very own manpower and is actually affordable. It's nothing more than an emergency device, but cool nonetheless. Makes me dream of some extended wild cave camping adventure 😉🌊

Does anyone have experience with it already?

Use a still, a big one, if necessary. Very low tech. Very effective. You can scale the tech to as large as you need, and if you're smart, you can use the heat to do a bunch of other stuff, too,since boiling water takes a lot of energy. (heck, you could hook up a small turbine and generate some electricity while creating drinkable water.)

Nice idea, love low tech 🙏 Yes, I thought about the distilling method, too. Got stuck with the thought of the original power input though: Carry the seawater, create a safe heat source (no open fires in the summer), and a lot of diy tinkering 😉 The turbine could reclaim some of the power. But I think at this point it'd be max worth the effort for producing drinking water not everyday use water.

You could easily make a rocket stove to set the still pot onto. No open fire, very efficient burn, easy enough to light and maintain.

Had my eye on rocket stoves anyway. Let's see what's possible 😉

Another device I came across to harvest drinkable water from the atmosphere and that's already available, proven and tested is from this company "Source Global". For around US$ 8'000 it can get you 7.5 litres per day, independently, without any additional power input.

For surviving way off grid this is pretty incredible already! But it won't serve all your household and garden water needs on your dry land.
