Editing Solar cooker (section)

== Box and panel designs ==
A box cooker has a transparent glass or plastic top, and it may have additional reflectors to concentrate sunlight into the box. The top can usually be removed to allow dark pots containing food to be placed inside. One or more reflectors of shiny metal or foil-lined material may be positioned to bounce extra light into the interior of the oven chamber. Cooking containers and the inside bottom of the cooker should be dark-colored or black. Inside walls should be reflective to reduce radiative heat loss and bounce the light towards the pots and the dark bottom, which is in contact with the pots. The box should have insulated sides. [[Thermal insulation]] for the solar box cooker must be able to withstand temperatures up to 150&nbsp;°C (300&nbsp;°F) without melting or out-gassing. Crumpled newspaper, wool, rags, dry grass, sheets of cardboard, etc. can be used to insulate the walls of the cooker. Metal pots and/or bottom trays can be darkened either with flat-black spray paint (one that is non-toxic when warmed), black [[tempera]] paint, or soot from a fire. The solar box cooker typically reaches a temperature of 150&nbsp;°C (300&nbsp;°F). This is not as hot as a standard oven, but still hot enough to cook food over a somewhat longer period of time.{{Cn|date=March 2025}}

Panel solar cookers are inexpensive solar cookers that use reflective panels to direct sunlight to a cooking pot enclosed in a clear plastic bag.{{Cn|date=March 2025}}

Solar Oven science experiments are regularly done as projects in high schools and colleges, such as the "Solar Oven Throwdown" at the [[University of Arizona]].<ref>{{Cite web|url=https://uanews.arizona.edu/photos/solar-oven-throwdown-heats-ua-mall|title=Solar Oven Throwdown Heats Up UA Mall|website=UANews|date=October 23, 2013|access-date=March 18, 2016|archive-date=March 26, 2016|archive-url=https://web.archive.org/web/20160326123746/https://uanews.arizona.edu/photos/solar-oven-throwdown-heats-ua-mall|url-status=live}}</ref> These projects prove that it is possible to both achieve high temperatures, as well as predict the high temperatures using mathematical models.{{Cn|date=March 2025}}
