They look cool, but I wouldn't trust their claims about being hurricane resistant. I've seen what hurricanes can do. As soon as a piece of debris smacks loose one bag, the entire thing is going to blow away. Sure, the "aerodynamic forms" may be able to resist hurricane strength winds, but that doesn't matter one bit once the aerodynamic form has been compromised. Imagine what one of those would look like after being pelted with bricks, thrown at 120mph, for 10 to 12 hours.
To me, their claim about "the aerodynamic forms resist hurricanes" sounds like a marketing person talking out of their ass. I'd really like to see proof of this before building something like that where I live.
Yeah i wasnt so sure about the hurricanes either, if a tree falls on it you're screwed lol. And im sure its not as resistant to earthquakes as they make them out to be. Still, its a start to having sustainable homes.

The following was taken from http://www.earthbagbuilding.com/Testing/superadobe.htm,
The Sandbag/Superadobe/Superblock technology presented here is the spinoff from several consecutive presentations to the space and planetary scientific community since NASA's first lunar base symposium in 1984. These concepts have been the subject of an intense research and prototype construction program since 1991. The research and development, engineering, and testing have been carried out at the Cal-Earth Institute under the scrutiny of the Hesperia Building and Safety Department, in consultation with ICBO. Building permits for the stock plans of 'Earth One' housing models as well as the Hesperia Lake Museum and Nature Center have been issued, and the Sandbag/Superadobe/Superblock building technology is recognized as a construction system.
_______
One of the most significant advantages of a domed or vaulted bearing wall structure is its performance in earthquakes. It is difficult to design conventional structures to withstand earthquake stresses. Their basic shape creates a severe problem, as the building weight is either uniformly spread from roof to foundation or, even worse, weights are often larger in the upper floors. With this propensity for overturning, the deeply planted footings and foundations rip apart at the very base of the structure during an earthquake, causing failures rather than preventing them. Modern earthquake design that incorporates foundation isolation does have shifting capabilities, but it is expensive.
A dome or bearing wall built on a floating foundation, the base isolated by a layer of gravel or sand, provides the ideal earthquake-resistant structure. The continuous or ring foundation can slide across the moving ground, while the upper structure, which diminishes exponentially in mass toward the apex, performs as a unified monolithic piece, eliminating local failure higher up the building.
Structural tests performed during intensive prototype research in Hesperia addressed both live-load and dead-load, static as well as dynamic loading forces. The structural engineering and testing procedures were conducted by Phill Vittore of P.J. Vittore, Ltd. The successful results were documented by an ICBO-approved testing laboratory, Southwest Inspection and Testing.
There's also a chronology of tests that were performed, please refer to the website to view them.
Flood control; erosion control; stabilization of waters' edges, hillside slopes and embankments; and retaining walls, landscapes, and infrastructures are applications in which the Sandbag/Superadobe/Superblock system has shown great potential.

nothing like sweat equity.. I've got a couple books on these things, they are awesome, but extremely labor intensive. Make friends with a civil engineer if you want one of these things permitted. Often times they can go off of New Mexico's adobe codes... place in the east aren't familiar but these can be approved.

I know quite a few people who are living in earth bag homes that they built from scratch. I was hoping to stay in one when I took the train out to New Mexico. Next time!

If I ever get a house with some property attached... I'd love to make a small earth dome in the back to camp/eat/smoke drugs in. like a little retreat hut.
