Question: How does convection occur in solar cookers?

Answer: Generally convection is not used in soler cookers because it offers a less efficient use of the available heat. Most solar cookers fully enclose the cooking space making use of the greenhouse effect. This allows sunlight to enter the cooking space which heats an internal element (metal cookwear for example). By completely closing this internal element (with an oven bag for example) heat radiating from the internal element is trapped within resulting in increased temperatures. Solar convection cookers could be created where the sunlight would heat an element the design of the oven would result in that heat rising into the oven before eventually cycling after cooling and being reheated. While less efficient this type of design would ensure more even temperatures in the oven due to the moving air and might produce better results when cooking.
