Several types of solar cookers exist. Here are photos of some of them. As with most solar cookers, always wear eye protection to protect your vision from the extremely bright light that cookers can create.
Box cooker
Box cookers contain the heat inside an insulated box with a glass top. Reflective collectors push the suns rays into the box. This box reaches temps of up to 325F.

Parabolic Mirror
Parabolic mirrors or shapes reflect light from the sun onto the cooking surface. This homemade parabolic is heating water until boiling. The homemade tripod is holding the pot in place.

Fresnel Lens
A fresnel lens concentrates the sunlight into a focused point. This typical fresnel can create so much heat that it can boil water or cook food. It can start a fire on straw or hay within less than ten seconds.
