Earth ships

So on one of my trips this summer, I went to Taos, NM for training and came across these 'earth ships'. I had never seen anything like it before and after riding by them for a couple of days, my curiosity got the best of me and so I paid the entry fee to get to check one out.

They are built into the ground, have solar panels, a grey water system, 'green house' inside and most of the building materials are from reused products. Not the most beautiful homes but whatever floats your boat eh? There was a whole community of houses and they drew a lot of curious visitors.

Walkway to the earth ship...
The wall that really caught my eye when we were riding by...
Thank you beer drinkers for your contribution...
A close up of the wall...I'm pretty sure this is eventually covered...

Glass bottles and cans in a decorative pattern...

No this isn't a trash pile but rather building materials....
So they cut the top ends of the bottles off and tape the bottoms together w/ duck tape and the bottoms is what you see sticking out of the wall. I think the bottles help with insulation? Total guess on that one.

So before you build your dream home don't forget to look into having an earth ship!
