The James Dyson Award is an international design award that celebrates, encourages and inspires the next generation of design engineers. The Award is open to current and recent design engineering students. It’s run by the James Dyson Foundation, James Dyson’s charitable trust, as part of its mission to get young people excited about design engineering.
Or so goes the blurb!
Have a look at the project gallery here but one that caught my eye was the Wat’Bag, an entry from Chloe Louisin and Nadine Nielsen, an Industrial Design students at France’s Strate École de Design.
Transporting clean water, aan keeping it clean is a challenge in third world countries but there are usually numerous plastic oil containers and old jerrycans available. These would make excellent water containers except for the simple problem that they would contaminate the water. The Wat’bag, is a flexible plastic insert with its own neck and resealable cap, it can be simply inserted and filled, the water expands the bag to the available space, kept completely separate from the dirty content.
This is a brilliant idea with obvious HADR and military applications.

As someone who spends a lot of time in Africa, I think I’ll get some :-)
There is a mistake in this article, there are 2 designers who created Wat’Bag, the other one is Nadine NIELSEN
