Earthships can be built in any part of the world, in any climate and still provide
electricity, potable water, contained sewage treatment and sustainable food production.
An Earthship is a type of passive solar house that is made of both natural and upcycled materials (such as earth-packed tires), created by Earthship Biotecture of Taos, New Mexico.
Earthships are thermal mass homes first,
passive solar homes second.
Meaning: Whatever temperature goes into an Earthship, it will hold… and since it is also a Passive Solar House, it is also very tight and interacts only with the sun and the earth for heating and cooling, providing stable comfort year round in any climate. This results in being able to provide a sustainable home on property that may not be situated to the ideal of 13.5 degrees east of south.
Earthships maintain comfortable temperatures in any climate. The planet Earth is a thermally stabilizing mass that delivers temperature without wire or pipes. The sun is a nuclear power plant that also delivers without wires or pipes.
Earthships produce their own electricity with a prepackaged photovoltaic / wind power system. This energy is stored in batteries and supplied to your electrical outlets. Earthships can have multiple sources of power, all automated, including grid-intertie.
3) Contained Sewage Treatment
Earthships contain use and reuse all household sewage in indoor and outdoor treatment cells resulting in food production and landscaping with no pollution of aquifers. Toilets flush with greywater that does not smell.
4) Building with Natural & Recycled Materials
House as Assemblage of by-products: A sustainable home must make use of indigenous materials, those occurring naturally in the local area.
5) Water Harvesting
Earthships catch water from the sky (rain & snow melt) and use it four times. Water is heated from the sun, biodiesel and/or natural gas. Earthships can have city water as backup. Earthships do not pollute underground water aquifers.
6) Food Production
Earthship wetlands, the planters that hold hundreds of gallons of water from sinks and the shower are a great place for raising some of the fresh produce you’d like to have in the winter, but find expensive or bland tasting from the supermarket.
An inspiring and personal story about a group of people building sustainable housing in the Baja California peninsula in Mexico, it also serves as an introductory guide to building alternative sustainable housing, as well as describing with the use of animation, how these buildings offer solutions to today’s most important issues like: energy,water,food, shelter, sewage and recycling.
