Earthships are 100% sustainable homes that are both energy efficient and awesome to live in. They offer amenities like no other building style you have come across. For the reasons that follow, I believe Earthships can actually change the world. See for yourself!
1) Sustainable does not mean primitive
When people hear about sustainable, off-the-grid living, they usually picture primitive homes divorced from the comforts of the 21st century. And rightfully so, as most sustainable solutions proposed until now have fit that description. Earthships, however, offer all of the comforts of modern homes and more.
2) Grow Your Own Food In an Attached Greenhouse or Aquaponics System
Most Earthships are outfitted with one or two greenhouses that grow crops year-round, no matter the climate. This means you can feed yourself with only the plants growing inside of your house.
You can also choose to build a fish pond and/or chicken coop into your Earthship for a constant source of meat and eggs.
3) Complete Use Of Water; It’s Recycled 4 times.
Even the most arid of climates can provide enough water for daily use through only a rain-harvesting system.
The entire roof of an Earthship funnels rainwater to a cistern, which then pumps it to sinks and showers when required.
That used ‘grey water’ is then pumped into the greenhouse to water the plants. After being cleaned by the plants, the water is pumped up into the bathrooms for use in the toilets. After being flushed, the now ‘black water’ is pumped to the exterior garden to give nutrients to non-edible plants.
4) Warm in the Winter & Cool in the Summer
The most brilliant piece of engineering in an Earthship is the ability to sustain comfortable temperatures year-round. Even in freezing cold or blistering hot climates, Earthships constantly hover around 70° Fahrenheit (22° Celsius).
This phenomenon results from the solar heat being absorbed and stored by ‘thermal mass’ — or tires filled with dirt, which make up the structure of the Earthship. The thermal mass acts as a heat sink, releasing or absorbing heat when the interior cools and heats up, respectively.
The large greenhouse windows at the front of the house always face south to allow the sun to heat up the thermal mass throughout the daytime.
5) Energy Creation and Conservation
Solar panels on the roof and wind turbines provide Earthships all of their power needs. As long as you’re not greedily chewing through electricity like a typical first-world human, you’ll never be short of power.
With all of your basic needs provided for and NO bills each month, you’re free! You don’t have to work a job you hate just to survive. So you can focus your time on doing what you love, and bettering the world around you.
Imagine if the entire world was able to focus on doing extraordinary things instead of just making enough to get by. Imagine if even 10% of the world could do this. What would change?
6) Easy to Obtain, Mostly Recycled Building Materials
Much of the materials used to build Earthships are recycled. For starters, the structure is built with used tires filled with dirt:
If there’s one thing we’re not short of on Earth, it’s used tires! There are tire dumps in every country in the world. There are even places that will pay you by the tire to take them away.
Earthship walls are created by placing plastic and glass bottles in concrete. When the Earthship team was in Haiti after the earthquake, they employed local kids to both clean up the streets and provide all of the bottles required for building their Earthship.
7) Thinking Differently
The most powerful thing Earthships do is force people to think differently about how we live. If housing can be this awesome, and be beneficial to the environment, then what else can we change? What else can become more simple, cheaper, and better at the same time?
It’s time for us to rethink much of what we consider normal.
