Interesting that they use some secret bio ceramic material. Otherwise, it's just geodesic domes. One thing I love about earthships is the open source-ness, and the focus on using local materials along side simplistic building techniques.
Yeah, the two guys developed it themselves, so good for them. Neither of them were material scientist is the cool part. I do like the openness and community of the earthships better as well. I was just blown away at some of the designs these people were doing... and I love geodesic domes!
Both the domes and earthships are solving the same problem while accessing most different markets. This is a great example of how there are many ways to do a thing but no best way, only different ways with tradeoffs.
