So- a 40-foot long cargo container weighs about 4.5 tons unloaded. It's difficult and expensive to relocate, requiring things like a crane, a smoking diesel-semi, and hundreds of gallons of fossil based fuel. Once it is converted to a living unit, it's very difficult to convert back to it's original more logical purpose. Is this True-Green or is this just more Green-Tagging? http://blog.leapadaptive.com/
