simple yet amazing

If they can actually get it out there for the projected price point, it could be a significant boon to those w/o sustainable water sources.

:thumbup: Definitely. I hope they do. It should be out this summer, so we'll see.
 
Hi Bushman,
Ron Hood demonstrated the use of a black plastic bag against a clear plastic bag for transpiration and the clear bag got water, the black didn't allow the water to condense. Maybe clear plastic is the way to go on this one?



interesting.....i guess i'm used to seeing solar heating systems (homemade, off the grid) where the pipes on the roof were painted flack black to absorb the sun better, compared to unpainted pipes.

I would have thought that a black cone would have heated up hotter.....


I have also seen a free system....2 liter pop bottles. The idea is you fill up the bottle (a whole bunch of them) leave it in the sun for the day. Apparently they are using it with great success.......i guess clear palstic or clear bottles do work.....

You want a black base and a clear cover to trap the heat.

SODIS. Radition and heat kill the "germs." Does not removed dissolved minerals like distillation does.

Yes, the UV radiation in sunlight really messes up the nasties in the water; it kills them or renders them non-pathogenic. The added heat speeds up the process. But as Thomas pointed out, it's not distillation so you don't get pure water. Biosafety cabinets in biological laboratories are outfitted with UV generating lamps (turned on when cabinets are not in use) for the same reason it's used in Solar Water Disinfection (though it's secondary to other means of disinfection).

Has anyone used one of those portable UV water filtration systems? I wonder how well they work....
 
Haha, yeah, mistyped that one.

I didn't know the Steripen was a UV system, I always thought it was a filter for some reason. Thanks for the thread link Thomas :thumbup: I probably wouldn't use one anyway, just more batteries to bring along....
