[Cob] Re: Cob: electrical

Dorothy,
    thanks for providing more information about electrical.   One point 
mentioned appears incorrect, but is not really a big deal.   I just want 
to point it out, though.

Air can  not dissapte heat, nor conduct it  much at all. 
In contrast, the aluminum in conduit or romex will conduct heat about 
9,600 times faster than air.   From the conduit it conduct into the cob 
mass.   Not, if wired properly there wont be a lot of heat running 
throught wires.  That's why there are wire size specifications to avoid 
heat problems.
