Watercone

Posted by Queuebot in Everything Else, Food & Drinks, Gadget on February 3, 2009 at 12:29 pm


Watercone is a polycarbonate cone with the capacity to purify up to 1.5 liters of water a day with just a little solar energy.

All users have to do to create drinkable water is pour dirty or salt water into the cone’s black base, place the cone atop it in the sun. As the water evaporates upwards it condenses on the cone’s inner wall and tricles down into a seperate trough. To access the clean water simply lift the cone and pour.

    I once saw a documnetary about a sailor who had to abandon his yaught and lived on the water from an inflatable version of these for 3 months.

    it would seem that 'target price of under $20' is way to high. surely if you got the kind of manufacturing that they use for coke bottles then you could get it to be much more like 20cents. make them stackable and ship them out to diaster areas (sunny ones) by the thousands

    I remember reading about this when I was a kid, you dig a hole and place a cup in the middle of it. You then cover the whole with saran wrap or clear plastic bag. Then drop a small rock in the middle, it takes the moisture from the soil, evaporates it and collects it in the cup.

    yeah, what jay say. the same can be achieved with two bowls/pans of different sizes, plasticwrap, and some rocks.

    Yeah that's what I was thinking, but I think this thing has a higher output that the old methods.

    Heh, I used to know people who distilled moonshine this way.

    Solar Still ftw! Yeah, this has been in the boy scout manual for, like, a hundred years. Or at least since the invention of clear plastic wrap. Much more portable than carrying around a satellite dish-sized rigid plastic cone (which no one will bother with during the Zombie-pocalypse).

    But this is far sturdier, and will help a lot of people in developing nations. Hurray!

    Don't be haters. This is a significant improvement on plastic wrap and makes up in durability what it loses in portability.

    A very cool device. I've been following its development for a while and the idea is simple yet powerful. The ability to create potable water from say sea water or dirty water can save hundreds of lives without the problem of spending alot of money on distilling plants.

    And kudos to Jay for pointing out the old, tried and trusted method of creating drinkable water from a still! :)

    Hooray for desalination. These should be standard equipment on any sort of life raft.
