Hot Bike in the French Qurter

Yep, I'm going build a strawbale dome

I have found almost no information about anyone building a strawbale Dome. To begin with, I am thinking of digging a 5 foot deep circular trench. Filling that 6 inch deep in rip rap (rubble). on top of that place a foundation of sandbags another 5 foot tall. placed on top of this is a half inch conduit buckyball dome bolted together. then a strawbale dome covered, or rendered in papercrete sprayed on the inside and out. to top it off paint it with prickly pear paint.
