"Andreas Keller, a master's student in South Africa, wanted to find an
environmentally friendly way to improve people's living conditions in
the country's shanty towns.
The idea he came up with is the
eco-friendly i-Shack - insulated with cardboard, complete with a
rainwater harvesting system and solar-powered electricity.
Thanks to a grant from the Bill and Melinda Gates Foundation, there are plans to build 100 more i-Shacks."
This is grreat. Very simple, passive design that vastly improves the living conditions of shanty town dwellers. Sometimes simple things can make a huge difference.
