What is an earthship, you ask?
Let me tell you. The earthship was the brainchild of one American man named Mike Reynolds who began experimenting with different types of architecture in the 1970s.
Reynolds dreamed of a home that would be entirely self-sustaining, using natural materials indigenous to the area or recycled materials for building, with the home being able to generate its own electricity, heating and cooling, as well as cleaning and collecting its own water, and in many cases even incorporating greenhouses within the space to grow some or all of its own food. These homes would be entirely "off the grid", so to speak. As the concept developed over the years, Reynolds began even creating subdivisions of these homes that from outward appearance, looked much like any other neighbourhood. The difference is, the people living in these suburbs had annual combined utility bills of $0-100, cheaper building costs and healthier indoor space.
The idea experienced a lot of flack in the beginning. The American government nearly shut down construction and research permanently as it hammered Reynolds with red tape involving what a legal subdivision should entail and denying him permits or permissions to build any new structures. As with any new technology, some kinks needed to be worked out. The technology is getting better everyday, as more homes are built and more people learn the trade.
The first homes had difficulty being entirely "off-grid"; some complained about extreme temperatures or lack of water or other comfort issues. Many of the first homes had composting toilets, but are now mostly using a system involving a solar-enhanced septic tank with leach-field and planter cells. As time went on, these kinks started to unravel and the technology got better and better.
Mike's most common design involves using recycled tires and ramming them full of earth until they have great load-bearing capacity, thermal mass and resistance to fire. They are then plastered and decorated. You would never know they were once old tires. So why are we not building homes using these types of technologies yet?
It's coming, slowly, but surely. People seem reluctant to invest in something they consider "experimental", especially when they themselves and their families will be living within it. Earthship rental properties available in Taos, New Mexico that offer people the chance to see what it's like to live in this type of home seem to be an encouraging idea.
There are several under construction right now in Ontario. Check out here and here for some more details. Want to learn some techniques how to build your own earthship in Ontario? Check out here and here.
Mike even exported this idea to tsunami victims in Southern Asia to help the local population rebuild cheaply, sustainably and in more weather-resistant ways. This technology is now sprouting up everywhere, with earthships from Nicauragua to India. There is a really great documentary now available on Mike's struggle to bring out this technology called Garbage Warrior. I highly recommend you check it out!
