What are the different types of solar-powered cookers?
There are basically three types of solar-powered cookers: a solar oven, a solar panel cooker, and a parabolic cooker. Parabolic cookers are like shiny satellite dishes that focus sunlight on a central point. Their concentrated focus can generate extreme heat quickly and can actually be used to fry food.
