I just watched the documentary Garbage Warrior recently and it totally blew my mind.

I’ve been aware of Earthships for a few years now and ever since then, whenever I fantasize about my dream home the only thing I can think about are Earthships. To put it as briefly as possible, Earthships are self sustaining homes made out of recycled materials like tires and cans that are covered with mud. They are designed to be completely self sufficient. They store solar energy, collect rainwater, and can process their own sewage. The walls are designed to collect and store thermal energy, which is then radiated at night.  The temperature inside an earthship remains relatively the same year around. With a successful greenhouse/garden, a person could potentially self sustain on their Earthship and live completely off the grid at all times. And they are BEAUTIFUL.
