DailyDirt: Water, Water, Everywhere.. In Convenient Forms

from the urls-we-dig-up dept

Drinking water is available in many forms, often for a reasonable cost as it comes out of the tap. But once you put water in a bottle, many of the reasonable prices seem to disappear, and bottled water can get truly expensive in order to get the experience of tasting water — along with a few dissolved minerals — that has been locked away underground for a while (or frozen in a glacier). Here are just a few alternative ways to get drinking water without buying it in a bottle.

Water Wars

“Using a similar approach, the firm wants to cover the surface of a bottle with hydrophilic (water-attracting) and hydrophobic (water-repellent) materials.”(from the linked article)

I have seen a couple of these hydrophilic projects. One had thirty foot towers, a big plastic bag with a local wood skeleton holding it up that was providing like 25 gal per day, in Eritria, a desert local. I think they might cover most anything, or be really flexible in actual design. The issue is getting enough, say per rooftop, to satisfy the family (or in the case of apartments families) within.

Once the basic technology gets done, distribution channels need to go world wide and inexpensive (probably good looking too). Water, a requisite for life, should not come dearly to anyone.

Probably The Most Common Chemical Compound In The Universe

Just been reading in New Scientist how water actually degrades some compounds important to life (like RNA). So some researchers are working on the idea that life processes got started in the absence of water, and only later evolved to take advantage of wet conditions.

Or, in other words, early Mars was a better place for life to have got started than early Earth.
