This is a great intro post to Earthships. You've effectively doubled my current knowledge of their capabilities. These seem like they will become the standard home of the future once all of the crazy building rules start being ignored by more and more people.
If things align I'd definitely participate in your build when the time comes. It will be interesting to see how quickly the Portugal based ecoVillage is ready to do a build. With @eco-alex at the helm of that, it would be a great learning experience.
