I think this will not work. First of all, it needs fresh water to start it, and most third world countries are mostly considered third world because of the fresh water. Second of all, it takes too much time to set up. Lastly, it's not even out yet because the people are trying to make it "affordable" for the poor.

3.1 million children under the age of 5 die from starvation
livingbox is the first system built of it kind

how many school kids die from starvation?
