earthships are more than just some free electric from some pv's, ...they're homes that are designed to be completely self-sustaining so no electric bill, no gas bill, no water bill, no sewer bill, ...ALL infrastructure is designed and built into the building INCLUDING food production.
it's a beautiful concept that makes you almost completely free to use your money for things you actually want instead of having to spend 3/4 of it on bills.
anyway, here is a link to the Earthship website and if you know how to download torrents then go look for 'Garbage Warrior' and check it out.

i like your way of thinking, i've been always advocating permaculture.
I was browsing that earthship site, realized they ask 8k for only the drawing (design) of the home, isn't that to much?i have no idea of those kind of prices.
