[Cob] cleaner cob oven for the future - Joe's concept

[Ray Cirino]

Dear Joe,
Transition LA and some natural builders will be joining us on the first rocket 
stove workshop of our new design here in Hollywood. If you know anyone who is 
interested in joining in let me know. it's at a home with the first retro 
natural pool in LA. This oven will also have a steamer at the top to knock down 
the CO2 back to earth.   Each oven after this one will evolve into what will 
become a green power plant  for electric, water heating and safe energy cooking. 
I work from the largest waste stream of parts any where.
Regards,
Ray    


 The Great Challenges we now face as a species present the very opportunities 
that are giving birth to Ecological, Psychological, and Spiritual 
Sustainability.

Subject: cleaner cob oven for the future - Joe's concept

 Hi Guys,
 
I hope to make a cob oven/kitchen with some high school kids this spring.  My 
plan is to make a rocket stove feed tube and chimney (lined with vermiculite 
cob) that ends at the base of a thick (1/4" or thicker) round steel plate at 3 
ft counter height (manhole cover? too thick?) which forms the floor of the oven 
(similar but not exactly like Ray's sketch).  Can cook directly on the plate, or 
stack bricks on it to raise cooking vessel so food doesn't burn on bottom (and 
also gets the food into the hotter part of the oven). I will drill holes around 
the edge of the plate to let the heat rise along the interior cob wall of the 
oven (Quebec style shape).  I will do a chimney  hole with removable tight plug, 
designed to fit a pan on top (use chimney heat for frying).  Will try to 
integrate the hot water tubing somehow.  

 
For me: welding?  Fuggettaboudit. (though I do love that little teardrop thingy 
- reminds me of a fifties spaceship - put some grooves on it and you could make 
the chimney output all swirly (like that German water guy from the 30's 
(Schlauberger?))). 

 
Lots of vermiculite cob on top.  Counters with wood storage underneath.  
Designed to fit nicely under a premanufactured metal roof (anyone know where to 
buy a silo roof?).  I would form the cob oven the usual way: sand form on top of 
the metal plate, 4-5" cob over that, 4" (sides) - 12"(top) vermiculite cob over 
that.  Let it dry sloooowwwwly. Probably some metal mesh in there to help 
preclude cracking.  feed tube hole area = holes in plate area = chimney hole 
area (I think that's best - heating engineers?) 

 
It would let smoke into the cooking chamber, but that's ok with me.  I think it 
should work: can cook right away, but also have heat containment in the cob for 
baking.  This would be oven 8 or 9 for me.  Comments welcome.  I will try to 
sketch it if I can find an easy techno way to put it on line (I am still the 
luddite mudman at heart).
 
Best,
 
Joe Kennedy
