It looks beautiful and it sounds like it could be affordable. This kind of thing really excites me.
However I have some questions about the design.
Those ceramic tiles look really cool. They seem to be burnished on the outside. He talks about the cure time being really quick but wouldn’t you still have to fire them? Many kilns wouldn’t fit something that large.
Another thought is that this seems like it would be terribly insulated. Like wouldn’t the ceramic be conductive? I doubt the hemp fibers alone is enough of a thermal block. There might be insulation between 2 layers of tile but the ceramic frame itself seems like it would not be great. I wonder if it would be possible to use timber for the frame?
I also think realistically, you need at least one large flat wall for things like an electrical panel/sub panel and battery banks. In the current configuration, the small dome seems like this is less suitable for a home and more for storage or maybe a green house assuming it doesn’t get too cold inside. Maybe it could be improved if it was semi subterranean or had a heat sink like a fish pond?
