we explored the possibility of using locally sourced or
innovative insulating materials. Initial experiments were conducted during a week-long workshop
of the collaborators at Davis. We determined the insulation value of feathers to be considerably
higher than shredded paper and polystyrene “worms.” As an example of a possible construction
method for an inexpensive and well-insulated cool room, we built a prototype “straw bale
cooler,” using local wheat straw. Given the time that the collaborators were able to spend at
Davis, the room was not completed and equipped, but the viability of the straw bale cooler was
clearly demonstrated.
