Xochitl Cruz, Jocie Kluger, Emma Lejeune, Meghan Hilbert, Alex Huang and Tim Bond (Tim writing) of the CEE3090 Solar Cooker Project visited Las Mujeres... and Grupo Fenix this spring in Sabana Grande during spring break (March 16 through 25). Lee Fritz and Jenna Morse of Calm Dog Productions documented the projects on film. We left Ithaca on Friday night driving to JFK to catch a 6am flight to San Jose, Costa Rica followed by a flight to Managua. Karen Holway, a skilled furniture maker, joined the team in Managua for the third year, lending her considerable skill and talent. The primary intent of the project for this year was to design and build versions of cookers designed for prefabrication and easy shipment. The standard cooker design is 30 inches square (exterior), 12 inches high and weighs roughly 60 pounds. It is an effective cooker, but is not easy to ship, especially with its heavy and brittle double glazed top. Click here for pictures from our trip.
Our team brought 2 new designs. A major point of the designs was to use materials readily available in Nicaragua and and methods the Solar Women already understand. The first cooker used wooden framing, fiberglass insulation and sheet metal typical of the cookers produced at the Centro Solar. This cooker weighed about 50 pounds and used Reynolds cooking bags stretched on thin metal frames instead of glass for the top glazing. Both metal cases were hinged to allow easy folding. The cooker was partially disassembled and packed in a cardboard box which was checked onto the airplane for the trip, to prove its transportability. We reassembled the cooker after arrival in Sabana Grande. The second cooker used interior and exterior sheet metal boxes framed with light aluminum angle stock. The boxes were separated by a layer of fiberglass board insulation. The tops of the two metal cases were tied together by screw connection to a rectangular wooden frame which supported the door/top. The door/top also used cooking bags stretched on thin metal frames as glazing. This cooker weighed approximately 30 pounds and was brought with us inside a suitcase.
