[Cob] insulation thread

[Bill&Julie]

Ah Ha,,, JON,,,   °¿°  We gots a think fest going....

The idea of an Earth Berm is a good one for a wind break.
But Cob does not like dampness, that is why we must use
a stem wall to break the whicking of ground water.
So if the berm were placed far enough  to allow solar collection,
but in a configuration to shoot the wind up and over, then we should
see a gain in heat ...
