Amazing: a pile of earth, dug out from a building site, can be turned into a small house called an Eco- Dome.
The folks at the California Institute of Earth Art and Architecture teach professionals and students from all over the world how to build structures like this.
This Superadobe technology was first presented to NASA for lunar habitats, and can build single or clustered homes on earth which are resistant to fire, floods, wind storms and earthquakes. Long sandbag tubes are filled with earth and compacted in layers which are reinforced and connected with barbed wire.
The man you see narrating in this clip is architect and author Nader Khalili who developed the simple breakthrough building technology with the freely available material of earth, for almost thirty years.
Nader Khalili passed in 2008 but has inspired a global movement and left a rich body of philosophy, design and innovative construction technology. His work is continued at Cal-Earth Institute, as the basis for its research and educational mission.
