What's an Earthship?
An Earthship is an off-the-grid home built from tires rammed with earth for thermal mass (the earth is a constant 57 degrees) heated and powered by the sun. The roof collects rainwater which is re-used to water indoor greenhouses that grow food and flowers. I have been living in mine for a dozen years and have tomatoes growing in my bedroom! I can't imagine living any other way now. No need for utility bills when the earth gives us what we need for free!
