Earthships are made out of recycled materials, such as tires and soda cans.
Earthships catch water from the sky and use it up to four times.
Water is heated from either the sun or by natural gas, but they can have city/county water as a backup water supply.
Earthships produce their own electricity, but can have multiple energy sources such as solar and wind-generated energy. The energy is stored in batteries and supplied to electrical outlets in the home.
Earthships contain and reuse all household sewage in indoor and outdoor treatment cells. The waste is used for food production and in landscaping.
Earthship toilets flush with greywater that does not smell.
Because of the way they’re built, Earthships maintain comfortable temperatures in any climate.
