An Earthship is a type of passive solar house that is made of both natural and upcycled materials (such as earth-packed tires). Earthships can be completely off-grid or partially off-grid.

Earthships can be built in any part of the world, in any climate (with a permit) and still provide electricity, potable water, contained sewage treatment and sustainable food production.

Whatever temperature goes into an Earthship, it will hold… and since it is also a Passive Solar House, it is also very tight and interacts only with the sun and the earth for heating and cooling, providing stable comfort year round in any climate.
