Watercone
came across this at another forum
now i'll be looking around the stores for something similar to the top http://www.watercone.com/product.html http://www.flatrock.org.nz/topics/en..._max_daily.jpg |
Re: Watercone
It is only be used to warm climates or at best 2 and a half seasons out the year.
It would still be a very good thing to have. What was the cost?? is it available in the US? T |
Re: Watercone
anyway, i was thinking of what i could use to dublicate this watercone
maybe a large funnel ( plugged at the hole ) and an upside down jello mold ? would a black plastic funnel help in the sun ? would a metal funnel heat up more in the sun ? http://www.powerchutes.com/graphics/perkfunnel.jpghttp://www.emiliesshoppe.com/images/...n/porc1081.jpg |
Re: Watercone
The cone has to be see through or transluent( I think )to get the heat caught between the water and the plastic.
Opaque will just make it really warm. T |
Re: Watercone
good point, i'm sure there are lots of clear funnels out there
another possibility is a clear glass bowl on top of the jello mold ( punch bowl ? ) somethinng to experiment with come spring . . . didn't look thru the whole website, didn't see a price EDIT: one of the pictures had a price of $60-$100 ( for one ? ) i'll improvise my own |
Re: Watercone
saran wrap taped to an emergency candle perhaps?

Re: Survival Water Still
That funnel thing is very slick-looking, but not a good deal really. With some clear poly sheeting you can make your own setup.
The top covering needs to be clear, so that the sunlight heats the underlying material warmer than the top cover is. The classic way to do this is to dig a hole in the ground. The ground is dark and heats up well, plus there is more water down in the ground than at the surface. http://images.google.com/images?um=1...=Search+Images If there is vegetation about, you can extract water from plants by placing the plants under the plastic as well: http://orochiyamazaki.livejournal.com/116998.html -end- |

Re: Watercone
Now I am beginning to wonder, , , , if you lived in an area that was usually sunny & hot (I'm planning on moving to the desert-southwest US) and you built one of these, but a lot bigger, how much water could you get from it in a day? All the sites I have found so far only talk about building little survival-type ones for temporary use.
From looking online, I've found rolls of clear poly plastic 20' wide and 100' long for around $100. Say you dug a pit that was roughly 18 feet square, a few feet deep, and covered it with a 20' x 20' sheet.... The edge of the pit basically isn't going to wear out at all. And that piece of plastic would cost around $25,,, but a gallon of distilled water costs $1 to buy right now. I'd be willing to bet that a sheet of that plastic would last at least a month in the sun--and in that time it would probably collect way more than 25 gallons of water. You still might want to chlorinate it before drinking, but it is interesting. It seems pretty easy, but I don't think I have seen any off-grid house using this method for collecting water.... -end- |
