Little available fuel, no-costs, preventing deforestation and pollution, recycling waste, save cooking.

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

One main point is that 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).
