Cob: air exchanger in cob house..was Jills Q

[Charmaine]

Hi Jil & /Patricia..I will see if I can find the TMEN artricle I dont 
have all the old issues, but many many of them
But as one suggestion...almost OVERLY simple is that Kelly Hart who 
built an earthbag home used  a simple plastic conduit pioe ( it could be 
anyother material too), that passed thru between bags of the wall and in 
summer they leave it open for air.  In cold/rain weather they simply 
used a child's blow up ball ( smaller than soccer ball) stuffed into the 
"porthole" tube, then a string ot short stick attached to it to pull the 
ball  out again. A screen on the end of the pipe prevents critters from 
entering.

While this would be a PROBEM in rainy Pac NW. from the way Kelly did it. 
  I would simply ALTER the angle of the pipe to be  downward thru the 
cob to Outside, and maybe cob in a cute little recycled wood shingle 
over the porthole as an eyebrow rain shield...sounds cute as heck to 
me...and HEY I know where you can get the best,  "thick butt cut" 
redwood shakes  that have been reycled.

Woman here in town  saved about a billion of them when they came off the 
local college roof and were headed for landfill. Bless her heart, 
 bought a bunch and used them  myself for one wall of the house, and 
will use the rest to make a retro groovey 70's back to the land 
doghouse..hahaha
