AQUAPAK

While narrowing my direction and searching for inspiration I came across the AquaPak in "Design Revolution: 100 Products that empower people".  

The idea is simple.  

Designed for people in rural areas who do not have access to clean drinking water and need to travel by foot to obtain it.  While walking back home the pack takes in sunlight, heating the water to 152 degrees thus reducing the presence of all pathogens by 99.99%.

"Made from a low-cost polyethylene with UV inhibitors, the sealable bag has transparent bubble-pack sheeting on one side and an opqaue black surface on the other.  The black side aids in the heating of the water...."

"Depending on the availability of sunlight throughout the day, an AquaPak bag can produce up to 4 gallons of sage drinking water, enough for a family of four for one day."

I believe this bag can be improved in a few ways.  Size. Durability. In/Out valve (clay filter?).  A hose to drink from (camelbak).
