Ooooo! I don't know about the wofati geodome, but that first picture of yours sure got my idea center working! I can see a tiny home inside a geo-greenhouse with a bit of planting space all around the inside.
Should at least make winter heating of the home lots easier.
On the wofati geodome, you could always add extra bracing within each triangle. Might also need some serious support inside to hold the dirt back. Interesting idea. I love domes!
Oo, oo! Or perhaps a circular structure of logs just inside the dome where ever pressure would be applied from outside. Kind of like a concave(or is it convex) dam? Any pressure from outside would make the joints stronger.
Oh shoot. How am I going to get to sleep now? This is too cool!
