I have a question, would it not be a stronger build, if instead of blocks, which from what I understand, loses strength, to have preformed dome shapes that are put together to make the building? Sort of like the Japanese company only with the aircrete instead of foam shapes like they make, they are almost the same idea, aren't they? And has this aircrete been actually tested in all the above situations?
Aircrete appeals to me more than the earthbag for simple reasons, it's physically more appealing to look at and if less labor intensive and quicker to put up? Yeah, that's a sale.

And if these structures were built alot, I'd seriously consider them. Because you won't be able to be in any town or city and build one without a huge amount of hoops to jump thru because of zoning, in the USA, but outside of a town you could do it. Anyway, thanks for this post!
