I'm two weeks into my Earthship internship here in Taos, New Mexcio.
Check it out here: http://earthship.com/Learn-More/internships. There's also a movie, Garbage Warrior, to watch here: http://www.youtube.com/watch?v=G7h1eRiJwow.
Since I've been here, I've been mixing and pouring concrete, constructing wooden window and door frames, pounding rammed-earth tires, leveling ground, building plaster and aluminum can walls, plastering a hay-bale wall house, and learning about passive heating, solar gain, passive water collection, composting, on-site sewage management, and many types of plant-growing methods. I've met a lot of great people with passion for learning and architectural experimentation.
