The Watercone® is a solar powered water desalinator that takes salt or brackish water and generates freshwater. It is simple to use, lightweight and mobile. The technology is simple in design and use and is discribed by simple pictograms. With max. 1,6 liters a day the Watercone® is an ideal device to cover a childs daily need of freshwater.

2. Truly uplifting. I love stories like this. This reminds me of a story I saw several years ago

about a Canadian invention that used fine mesh to collect morning dew then siphon it into barrels. Utterly surprising how much fresh clean water was collected daily.

3. This is what we were shown in camp some years ago... and by some I mean some.

We were told to cut up some green plants, cactus, whatever and place it in the hole around the glass/cup and let the sun do it's thing. The medium is cellophane, the small stones obviously hold it in place.

5. Old Survival School trick

A sheet of thin Polyethylene is much easier to fold up and put in your pocket. Rocks not included. This works very well on a Beach, where there is a constant supply of Salt Water.

6. can probally find some hemp-plastic be more healthy

hate to think of the chemicals leeching out of petro based plastic

7. Nothing to leach out but Carbon Dioxide and Water

...and only infinitesimally small amounts as UV radiation breaks down the Plastic. That's why I mentioned Polyethylene.

Now that you mention it, Cotton or other natural Fiber string can help wick the clean Water to the collection point.

The most likely scenario is being stuck in the Boonies with a bag of Cheetos and a Roach. Most people don't plan ahead for this type of situation.
