I love the low-tech solution to the problem! Not much more to say, I just think it's a great a solution that will go a long way to both helping the people in this area of Somaliland, and serving as a template for similar projects in other regions of the world.
- wolfram74 6y agoI'm curious what the life expectancy of the cardboard evaporators are, I'd have guessed they would either mold over or just fall apart from being soggy all the time. Color me surprised.
