I like that term. I might just start referring to myself as a hippie-tect. Thank you Dwell posting on Earthships.
What appeals to me most about Earthship construction (and it is not the aesthetics) is that they demonstrate how a lot of our industrial infrastructure could be decentralized. Need power? Use photovoltaics! Need water? Set up a cistern and greywater recycling! Unwanted waste? Compost it!
It becomes possible to imagine existence without reliance on a corporate/state controlled utility apparatus (except to produce the PVs). Which is exciting.
Indeed – earthships are the way of the future… http://www.earthship.org
