Cal-Earth - The California Institute of Earth Art and Architecture is teaching those who are willing to learn, how to create homes that are made from the earth, imitate nature and are nearly Mother Nature proof. The goal is to teach people how to make these inexpensive and sustainable structures so that they can go around the world sharing their knowledge and helping those in need. The structures are made from sandbags and barbed wire, which they have named "Superadobe." The design and shape of the structure came from observing nature (think shells and bee hives), as well as, techniques from the great builders of out past (domes, vaults, etc.). The domes have been built to withstand the impact of heavy snow, flooding, extreme heat and other treachorous conditions that can cause homelessness.
Being able to use plentiful and local materials to create structures that can save lives is an amazing gift and I hope to see more "kind-Earth" thinking of this sort. I am very eager to go out to CalEarth and explore their domes myself and maybe even take a class.
