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.

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

Heh, I used to know people who distilled moonshine this way.
And kudos to Jay for pointing out the old, tried and trusted method of creating drinkable water from a still! :)
