A good information source is Solar Cookers International’s own manual: Field Guide: Spreading Solar Cooking. These items on the manual’s assessment check list can be affected by cultural variability: * Are there open, sunny spaces near homes, where a solar cooker and food can be safe from theft, tampering, or damage? * Is cooking already usually done outside? * When are primary meals served? Around noon and/or around sunset or soon after? * Do gender roles allow and/or encourage women to participate in community groups and decision-making in family financial matters?
