Describe a box cooker?

A box cooker is a type of solar cooker that consists of an insulated box with a transparent lid or cover. The box is typically lined with reflective material to maximize the amount of sunlight that enters the cooker. Inside the box, there is a cooking chamber where food is placed to be cooked using the heat generated by the sunlight. The transparent lid allows sunlight to enter the box and trap heat, creating a greenhouse effect that cooks the food inside. Box cookers are a simple and efficient way to harness solar energy for cooking and are often used in areas where access to traditional cooking fuels is limited.
