I first saw these years ago, then more information became available when Dennis Weaver built his Earthship. The overall designs are reminiscent of David Wright, AIA, who published some books in the 60's/70's of some passive solar homes in the southwestern US. I wouldn't be surprised to find him involved in the Earthship concepts.
Although most of us cannot include ALL the concepts in one package, it really is nice to see that some can!
Here are 2 introductory film clips... Part 1 and Part 2
