I really like the idea but I get the feeling that the Earthship org is a sex cult. The guy running it exclusively recruits college aged people and he sends the men off to ram earth in tires. I think the idea needs to be modernized. Using a sledgehammer to ram earth is extremely laborious and the whole "only use found materials" thing is kinda dumb.

Over the years I've accumulated like less than 10 used tires; hauling more would have same impact (or higher) as using local rocks, clay, even wood from thinning.

Eco building is no one-size-fits-all, you've got to use what you have and use your imagination - that's the main lesson earthships teach us. There is absolutely NOTHING special about particulars. Design is cool that's for sure, but then again, not my style.

Myself, I steer more to the school or Mark Oehler and Paul Wheaton, although using their ideas directly is totally infeasible in my place (it's a swamp), the approach is very exploitable.

Very cool!! The architecture reminds me vaguely of the Xanadu Houses (which I was obsessed with as a kid, they had one in Wisconsin I visited a couple times).

'Ship' means 'vessel for navigation' so I do not like - if it doesn't travel

Old tires are carcinogenic and microplastic nightmares. One should be very cautious about living in structures made of them.
