Ken Kern quotes
Around 1800 American-born, expatriate Benjamin Rumford discovered that once heated, a firebox built of masonry materials did not cool the fire. Instead, it slowly built up the heat that kept the fuel in the firebox burning hotly. He joined the growing debate between builders of metal and masonry stoves, contributing considerable support to the latter.

It is a rarity of the first order when the dean of an architectural college takes it upon himself to build houses comprised of woven split bamboo placed between two layers of treated clay. These readily available materials were artfully used by Professor Stein in his creation of two demonstration low-cost homes.

The concrete shell of this stove would surely crack if its strength were not reinforced with steel rod, wire fabric, or barbed wire. The latter is our choice. We laid continuous strands of barbed wire between the rows of slip form masonry. The thermal expansion rate of concrete is the same as steel up to a temperature comparable to boiling water... Beyond that, steel expands at a faster rate than concrete. At a temperature of about 500 degrees F., the bond between the concrete and steel is destroyed... The type of aggregate in the mix is primarily responsible for this kind of failure.

Enough is known today about natural ventilation for summer cooling to warrant the entire replacement of artificial air-conditioning devices. ...prevailing breezes enter small, louvered openings at the lower section... circulate across the "living zone," rise and then exit through larger, higher openings in the opposite wall.

It is no mystery that clay cook pots perform as they do or that clay ovens are considered healthy devices for us to use. In prehistoric times, baking ovens were built of clay and sand. Later these stoves were placed inside shelters where they could deliver some of their accumulated heat to the household...

The Arab's tent... actually consists of two separate tents. The outer tent is white and acts as a heat-reflective layer. The lower-inner tent additionally protects... by providing a blanket of moving air between the two tent layers. ...this tent system also illustrates the two, most basic principles of summer cooling: reflective insulation and ventilation. ...One system must supplement and reinforce the other.
