@Martin10 if my calculations are accurate then you should need about 2800 blocks. This is assuming a consistent block size as your estimate for a 16 foot diameter dome. I simply took the square footage of a sphere of that diameter and divided that to get a per block ratio (.867 blocks per sq ft of sphere surface area calculated at some diameter) and scaled it. Assuming that you have The same fraction of the dome above the ground as in a 16 foot diameter dome that should be a rather accurate prediction. I could model it on CAD very quickly if you want to get a more accurate number. The fact that it is nearly 4 times the quantity also gives me confidence because the surface area quadruples as the diameter doubles...

I don't understand HOW your mixer works, but the blocks you made do look amazing. Do all your blocks look so good as that photo?

@Martin10 aloha i have a project starting in feb in hawaii can you come?

HI! I am a healer and I work in health and wellness. I would love to be a part of your project after you are done building.

I know so many practitioners and people who would love to do retreats and work there. feel free to contact me. stellafay@gmail.com

I have been thinking of this topic allot being that it seems to be the primary method of forming domes. The compass arm, and how one one chooses to use it, is a direct influence on the shape one ends up getting. Are there any more ideas by you Domies on how one could get interesting and structurally sounds dome shapes?

It should be possible with a compressive structure designed for the weight. However... I don't believe this is the best material for putting underground.
