"The other day I noticed that one of my tires had a slow leak. I took it to a place called M&M Tires, where it was expertly repaired within a few minutes by owner Bonifacio Martinez. While he worked, we chatted, and he remarked that, had he been unable to fix it, he might have donated the worn-out tire to the Earthship community, a few miles outside of Taos. I was fascinated by what he told me and decided to visit.
The Earthship community is a collection of unusual homes that look, at first glance, like something from a strange dream. They are organic in shape, studded with bottles, and partly buried in the ground. These are Earthships — passive solar structures that do not use any conventional power or water source, thanks to a combination of ingenious design, recycling, and solar and wind power. Water comes from snow melt or rain collection, and is used four times before it is finally discharged in a conventional septic system. The houses are amazingly pretty inside, airy and not at all dark.
The walls are made of recycled tires, aluminum cans, bottles (sometimes placed so as to let light in), and adobe, which is then oiled on the inside surfaces to make it darker, the better for absorbing sun and maintaining heat. Here’s a cutaway view of a wall:
Sloped windows on the southern side collect sun and also nourish the gardens that provide food, purify water, and beautify the space. When the sun is too intense, or to retain heat after dark, the windows can be covered:
The houses are wired with conventional electric outlets and the appliances are ordinary, albeit energy-saving models. They are priced competitively: a 1,200-square-foot home in this community might cost $200,000 (this includes all labor, the most expensive part of building an Earthship). Members of the Earthship Foundation have built them all over the world, and also are available to teach others. They have also published the building plans in several books."
