Cob heat storage

[Will Firstbrook WCB of BC]

Hi John,

I had this table kicking around

Cubic Material	BTU
Water	600 BTU
Stone	346 BTU
Concrete	294 BTU
Brick	273 BTU
Concrete filled blocks	273 BTU
Sand	252 BTU
Adobe	216 BTU
Wood	142 BTU

showing a heat storage table that lists the BTUs stored per cubic foot
of various materials for a ten degree F raise in temperature. This table
is from William Lumpkins' book of plans for passive solar adobes "Casa
del Sol", page 16.

I am not sure exactly where cob would fit into the chart but my guess it
is around that of adobe.

Regards,
Will

ps: I must say I like the the picture on page 12 of the new cobweb issue
6. The timber framed roof structure looks cool. I love the curved &
warped wood in the structure.
