First of all, I'd like to thank Derek for taking the time and effort to
compose the response that he did and as much as I hate agreeing with
anyone, I'm afraid that I have to do so wholeheartedly on this one.
I did start composing a similar "poop on the party" response but stopped
because there was just too much that needed addressing (as Derek so
bravely illustrated), eating up far too much time.
However, my guess is that Christopher and gang will choose to ignore the
"Ditch the dome idea" advice and go ahead with the scheme.
If that in fact turns out to be the case, I would suggest perhaps looking
at making something like a parachute that can be suspended over the straw
bales like a tent fly ... functioning like a ventilated rainscreen
cladding, el Cheapo/flimsy version, highly susceptible to being torn off
by high winds if an effective tensioning/anchoring strategy is not
The rainscreen does not negate the need for plastering the straw, inside
at the very least, for protection from fire, ... and outside as well if
keeping rodents, insects, vermin etc out of the straw and minimising
thermal-resistance-destroying air movement through the straw is desired.
Another approach may be to simply stack up the bales in the manner they
are best suited to be used (ie like big block) to make walls and then
hoist the dome up onto the top of the bale walls for a roof structure .
The shape of the SB-walled structure could be rectilinear making the floor
space more amenable to the rectilinear furnishings that people typically
own requiring less futzing with the straw bales -- something there would
be lots of (ie every bale would need to be custom re-made) if SB were used
to cover the dome.
