Oh my gosh! Oh my gosh! Oh my gosh!
Steri Pen. Handheld UV light water purified. Will someone please buy this for me and the other 1.7 billion people without access to clean drinking water?
Seriously. We've got a cholera outbreak in Juba and a Hep E outbreak in Kitgum. I could do some wicked good with about 1000 of these and a team of trainers.

Hm. What is the average size of a container used for porting water around in the places you've visited? I wonder how hard it would be to build one of these on a slightly larger scale. (Some water systems -- including the one I was on back in Pittsburgh -- use industrial sized versions of these, but that would require an crane to move around.)
