The SURE HOUSE is a project at Stevens Institute of Technology that is leading innovation in sustainable home building in coastal areas and beyond.  These guys just won the Solar Decathlon by the US Department of Energy.  But don't be fooled, many of the same processes, techniques, materials etc. are relevant in many regions not just coastal areas.  

We talk with Kelly Hart about earthbag building.  As a natural building proponent, I am really getting excited about the possibilities with this basic sustainable building material.  Think about it. We can use a product that in many cases can be used directly from the sit = low embodied energy.  There is missing audio about 5 minutes in...but just keep listening.  It is good information regarding earthbag homes and low cost building.
