sessionHistory Of Solar Cooking
The first known solar cooker was build by a Swiss naturalist Horace-Bénédict de Saussure in 1767.
Solar box cookers became popular in the 1970s when people began to be more energy conscious and looked for ways to harness the suns energy.
A French mathematician Augustin Mouchot combined the heat trap idea with that of the burning mirror, creating an efficient solar oven from an insulated box
Collect the Light
Collect the sunlight using reflectors with an approximately 400 square inch opening (20x20)
Easy way to measure: the minimum opening of the cooker needs to be the diameter of an adult‟s arm
Reflective surface materials include: aluminum, Mylar, aluminized Mylar of any thickness, aluminum or chromium paint (Note: mirror like reflectors can lead to eye damage)
Retain the Heat
Retain the heat –hot vessels lose their heat to the air quickly so they need to be covered
Cover with plastic, glass, Plexiglas, or tempered glass
A tight lid will trap steam and speed up cooking Ex: Canning jars work like inexpensive pressure cookers
Types Of Solar Cooker
Box cooker
Parabolic cooker
Funnel cooker
Applications
Bakeries of lesotho
Michael Hönes Germanyhas established solar cooking in Lesotho
Enabling small groups of women to build up community bakeries using solar ovens
Solar kettles
