An Earthship is a radically sustainable home that does 6 basic things: 

1. Garbage disposal - Earthships are made with recycled materials.
2. Heating and cooling using thermal mass walls.
3. Water is caught on the roof from rain and snow melt.
4. Food is grown inside and outside. 
5. Electricity created with solar or wind modules.
6. Sewage is treated on site using botanical planters.
