Little available fuel, no costs, preventing deforestation and pollution, recycling waste, and saving on cooking.

Parabolic solar cookers are devices for preparing food that do not require fuel. They concentrate the sun’s rays to a single focal point, where a dark pot or pan can be used to cook. The link will direct you to a manual on how to make a solar cooker yourself from local materials and waste, using the bottoms of tin cans as reflective mirrors. This is a very low- or no-cost do-it-yourself way to make a functioning solar cooker. It works with good sunlight. However, do read the bottom paragraphs on conclusions and design alterations.

One main point is that the bottoms of tin cans suboptimally reflect sunlight, so using materials that better reflect the light is better (like pieces of mirror or flat tin surfaces).
