Earthship Volume III: Evolution Beyond Economics presents additional details and updated techniques to the art of building Earthships. Based on the accumulated wisdom of dozens of new Earthship projects from around the world, Volume III includes scores of new ideas and refinements to all aspects of designing and building efficient, low-cost Earthships.
Specific topic areas include refinements to the walls, bondbeam systems for the top of the walls, home-made trusses, retaining walls, gutter details, mudstone and flagstone floors, additional details on doors and windows, adding rooms to existing earthships, indoor and outdoor rainwater cisterns, additional water filtering information, improved indoor wastewater treatment systems, better solar power organization, back-up heaters, mud stoves, a thermal mass refrigerator, home-made solar composting toilets, and built-in solar ovens. Also covered are temporary structures to live in while building your Earthship, retroffiting an existing cracker-box house into a module within an Earthship, ideas for planning and initiating Earthship communities, proposals to apply the Earthship approach on a city-wide scale, building code recommendations for owner-builders and inspectors, applications for developing countries, and adaptations for unstable soils or marshy conditions.
In short, there is enough new essential information in this text to make it as essential as Earthship Volume I and Earthship Volume II. It compliments, but does not replace the material from the first two books. Solar Survival Press. 1993. Revised 1996.
