This is quite true. The difference is that water is a lot more palatable than pure ascorbic acid or sodium chloride.
Yep, I agree with all of this. The "8 glasses a day" thing was rubbish. You drink as much water as you need. And you can tell how much you need by monitoring the colour of your pee. Haven't heard that. Do you have a cite? I might need to modify my article. Oh indeed. I never said it was or should be. Again, you can tell very easily how much water you need by looking at the colour of your urine. If it's dark, grab a quick glass. That's all there is to it. |

Here's a decent overview: http://answers.webmd.com/answers/116...ine-a-diuretic
My understanding is that for regular caffeine consumers the amount of liquid water in the beverage more than matches any increased output. There's a parallel with low-alcohol beverages (although alcohol is recognized as a diuretic) where the volume of liquid consumed contributes to the urine output. Wasn't there a point in history where the usual beverage was not water (because of purification issues) but weak wine or beer? |

The second product I linked to (not Fontus) supposedly works down to 20% humidity.
In some climates the difference between nighttime and daytime temperatures may give huge relative humidity swings, so an area generally recognized as arid or low-moisture, may still produce a morning dew. This makes "dew harvesting" a possibility: https://en.wikipedia.org/wiki/Air_we...ew_Utilization |

Indeed, that's my understanding. It was safer to mix water with wine than to drink just the water. Diarrhoea dehydrates a lot faster than a weak alcoholic drink, and before modern medicine it was not unusual for people to die from it.
Thanks for the article, I'll check it out. |

Actually, there seems to be quite a lot more to it than that.
Drink when you're thirsty is a good gauge, how often you need to urinate is a better gauge. When working in extreme environments (cold, high or hot), we would use the whole urine color thing as an "advertising" reminder for workers to hydrate regularly. It is more of a meme than an accurate medical diagnosis. ETA: I have not read your blog on the subject, so you may have covered the above. |

OK, air and light. Air contains water and light contains energy. So it is possible to extract water from air using light. In fact some substances can do it without added energy (but then you need to get the water out of the substance).
As you say, it is likely to be a low yield operation, and I can't help wondering what need exactly it proposes to fill (regardless of whether it works or not). The number of people lost in some desert desperate for a few mouthfuls of water is not much of a business proposition. Hans |
