An LA-based design think tank called APHIDoIDEA has an idea about how to build an environmental education center that practices what it preaches. The designers imagined an Environmental Center of Regenerative Research & Education -- or eCORRE -- Complex that would teach visitors about green ideas like solar energy and passive cooling techniques. It would have classrooms, offices, an exhibition hall and a public plaza. Here's the cool part: the building would be made of 65 shipping containers.
