They're intriguing! I could envision a modular design with passageways connecting a few of the domes. I had no idea the Aircrete product was used in Europe but it doesn't surprise me they're that far ahead. We have so many barriers here in the States to new, innovative products like that. I need to look more into it. I wonder how tough it would be to get shipped to the Caribbean? Did you see Tesla's battery announcement yesterday?
