Earthen/Cob Floor

“Natural building expert Michael G. Smith from the Emerald Earth Institute shows us the first layer of an earthen floor (clay soil, sand, chopped straw and road base, or crushed rock): just one layer of the 3 layers they eventually use. He also shows us a finished floor that has been treated with 4 to 6 coats of linseed oil and is water resistant and completely mop friendly.”

It was nice to see a natural, durable floor that didn’t come from a factory.

Rocket Stove

“The Rocket Stove is a variety of wood-burning cooking stove. It is easy to construct, with low-cost materials. These are low-mass stoves designed to burn small pieces of wood very efficiently. Cooking is done on top of a short insulated chimney. The stoves are typically constructed out of trash: tin cans, old stovepipes, etc. A skirt around the pot will help hold heat in, increasing the efficiency.

Rocket Stoves use branches, twigs, small wood scraps, or just about any small combustible material. The pieces of wood or other material burn at their tips, increasing combustion efficiency, creating a very hot fire, and eliminating smoke. The low-mass stove body and insulated chimney ensure that the heat goes into the cooking pot, not into the stove. Rocket stoves used in conjunction with hayboxes can save enormous amounts of fuel, cooking complete meals while using very few resources.” You can read the rest of the descriptive article here.

In the following videos, Chris Towerton, shows us how to construct a rocket stove cob oven. He uses clay, a steel pipe and straw.:

Chris’ inspiration video was by Jon and Flip who have built these ovens for firing pottery and for baking/cooking food as part of their relief work in Haiti.
