Solar Water Purifier

Please see https://www.thingiverse.com/thing:3421671 for a new version of this concept.

I explain it all here, but Brian does a much better job in this industry write-up (I am so amazed and thankful for his efforts): http://3dprint.com/15917/3d-printed-water-purification/
Since early childhood I have always wanted to "make the world a better place", a quote from my youth. Now I'm 47 years old (going on 11 lol) and I have the time and resources to do just that. Here's how.
This simple thing is designed by myself to convert a trashed 2 liter bottle into a solar water purifier. You cut the bottle into two sections (cut as shown near the bottom) and insert this 3D printed ring-like object. Then leave it in the sun all day and at the end of the day there will be some clean water in the collection tray of the object.
What makes this invention so likely to actually be used is the following fact. If you give a desperately impoverished person an object with the intention of helping that person survive, what typically happens is the person will sell the object to buy food. Therefore it stands to reason that to help such a someone, what we give them must be basically trash that nobody wants and therefore has no sale value. So the recipient will keep it and use it for its intended purpose, in this case to clean dirty water.
I am giving this invention to the world, meaning whoever wants to take it to the next level is free to do so. I only ask that you tell me if you plan to help the poor with this simple idea / gizmo. Let's end human suffering in every way that we can!

p.s. i made a little video on this concept: https://www.youtube.com/watch?v=l-vKoAXX3QY&feature=youtu.be
p.p.s. i tested the object today (Tue Sep 16 2014) and discovered that it must be sealed to work. If not sealed, all the water evaporates out of the device! More details are in the Instructions section.
this video describes another technique that does not require a 3d printer at all: http://youtu.be/NnqQT287Rw4
