Solar ovens are devices that concentrate and retain heat from the sun to cook foods. They can also used to reheat or to disinfect water.

The ovens may have integral cooking containers²⁾ but more commonly a black pot is placed into the oven.

Advantages:

• free!
• “Low and slow”³⁾ techiques adapted from crockpot recipes may be useful.
• cooking outside prevents heating interior of vehicle during warm weather

Disadvantages:

• requires good sun
• wind can blow the cooker around
• wind will wick off heat from open designs
• can be bulky - look for foldable/collapsible designs

The acronym CARD describes what is necessary for solar cooking:⁴⁾

• Collection (reflectors)
• Attraction (black pots or painted oven bottom)
• Retention (“greenhouse” enclosure or insulated box walls with cover)
• Duration - time in the oven
