This is a video about Earthships: The Ultimate in Green Buildings. Earthships are designed and manufactured in such way to achieve thermal, solar heating and cooling, solar and wind electricity, they contain sewage treatment, catch water and are built out of recycled materials.
This is film about Big Sky Earthship. Despite sub-zero temperatures outside, the living areas maintain comfortable conditions in the mid-60s (F) in the living areas and between 70-80 degrees (F) in the greenhouse. All with $0 in utility bills!
