Heh, heh, that's pretty funny Paul!
I wish I were a little closer so I could see that machine in action--with
mud that is.
Are you talking about shooting regular stucco through that pump?
If one were to find custom made strawbales that were only 6 to 12 inches
thick, one could sort of simulate those 3-D Panels in a green way. With
cob on both sides. That would answer the perennial question: How does one
insulate cob? Alas, there's probably no market for any farmer to go to
that much trouble.
