The process of boiling requires the water to heat to 100 Celsius. Once it reaches this high temperature, it kills disease-causing germs. Pasteurization, however, requires the water only to be heated to 60 Celsius, but at a longer sustained heat. This can be achieved by putting contaminated clear water in a covered black pot (which can be painted with simple chalkboard paint) to attract heat, enclosed in a large clear plastic bag to contain the heat, and placed inside a Solar CooKit to intensify the heat.
The Global Women’s Water Initiative introduces the Solar CooKit as one of the core technologies women learn at our Women and Water Trainings. On Day 1, women make their own Solar CooKit! Made simply with recycled cardboard boxes, reflective material (aluminum foil, the inside of juice boxes etc), cloth for lining and reinforcing the edges, and glue. In just a few short hours the women have their first technology completed and ready to use!
During the rest of the Training week, they set the CooKits up in the morning if it’s a sunny day to clean their water, share recipes and cook delicious food. They leave them to sit in the sun while they spend the rest of the day in training sessions and building other technologies. When they return after a few to several hours (depending on the strength of the sun that day) their water is clean and their food is cooked!
There are so many reasons to love the Solar CooKits. All the materials to make the CooKit are available locally. Women have less dependence on coal and fuel and reduction in deforestation. Once they have the technology, cooking is free – on sunny days of course! And most important, women are freed up to do other things while they are cooking and cleaning their water. WIN for the women, WIN for the environment, WIN for family health!
You can make one too! Download the instructions and recipes here from the Solar Cookers International website.
