Passive Solar Earthship Homes
This video (in English, despite the title in Russian which translates as ‘house build from tires’) takes a look at “Earthship” houses in New Mexico. The houses are designed to be stand-alone, self-sufficient, off-grid units.
In this case, the “Earthships” have thick walls that allow for passive solar heating formed from rammed earth in recycled automobile tires. Empty aluminum cans and glass bottles also provide filler for the walls.
The thick walls can store so much solar heat that the inside temperature is easily a stable 70 F without additional heating, even on freezing days.
So, heating = solar passive via thick walls and window siting, energy via solar panels and wind turbines, water and waste = special filtration and septic systems.
