Hi,
I've been busy for a while. Glad to see things papercrete heating up!
Papercrete might be a choice for the bus, especially if small sections
were done at a time, with some kind of flex joints between them.

I agree with Perry's suggestion of foam. That can also be greener if
SoyFoam.com or other BioBased.net insulation is used. (Hi Perry - sorry
we didn't get LinkedIn)
I am not experienced with their use, but some friends down by the border
are registered SoyFoam installer. They have made a 350 gallon tractor
PTO-driven papercrete mixer, because they are looking for a more
affordable solution, as other bio-based insulation is proprietary and
therefore more expensive.
