Earthships are extremely  energy efficient homes constructed from earth and recycled materials. They are usually off grid and collect their own electricity and water. They are a great mix of old and modern technology to create great sustainable structures to live in. I know there are some Earthship homes in Arizona, but have never seen one up close. I’m really curious if they stay cool enough without A/C here in the desert.

The two videos below show what these unconventional homes are all about.
