How does it work?
Now that we know where to find the water, how do we get it? With the method Pavel Lehky invented, we don’t have to do much. Let’s get a closer look:
For this method, here is what we need:
First, we dip the towel in the Glycerine and fix it well on the clothesline. Now, the wind is just bringing the water vapor in the air to our towel and the Glycerine is going to attract it (Img. 2).
Then, we wring it out well and let the Glycerine-Water-Mix flow into our module.
The module includes a shell, a semi-permeable membrane (only letting steam through) and a corrugated cooling surface.
At this point, the sun is going to heat things up. But as water is steaming at a lower temperature than the Glycerine, it wil just be passing through the membrane while the Glycerine won’t be allowed to do so. That way, we separate the clean water from the Glycerine.
The vapor, once the membrane is passed, will condensate on the cooling surface as we saw it in the kitchen. The clean water now flows down the module and comes out, ready to drink!

For this method, here is what we need:
- some Glycerine: This substance is not toxic and attracts/is attracted to water (Img.1)
- a towel and a clothesline we can hang it onto
- some sun and wind
- and, of course, the module.
