The Squexad 5V30 solar panel cooker has been designed in Spain, with early prototype work that began in 2008. The design takes a fairly unique approach of using reflectors that stack up together. Much like a telescope, the stacked reflectors extend upwards to the sun. The top reflector segment has quite a large solar exposure. When done cooking, the reflector panels slip out from each other and fold flat. Disassembled, it makes a relatively small package for transport.
There is not a lot of information on the company website showing the cooker in use. Some concerns may include the ability to easily check the cooking food, and such a tall profile may be tipsy in windy conditions.
The cooker uses a tray for the cooking pot to be placed under the reflector stack, enclosed in a plastic cooking bag.
