It is an unreliable source of energy which takes a fair amount of time to heat anything to sufficent temperature when there are easier faster alternatives such as fire wood and gas.
The sun?
what can they cook? they dont have any food, therefore, no need for cooking utensils.
A solar furnace creates heat by concentrating sunlight through the use of reflectors. It is used for cooking and generating electricity.
A black pot is used in a solar oven because black surfaces absorb more sunlight and convert it into heat more effectively than lighter colors. This increased absorption enhances the oven's overall efficiency, allowing it to reach higher temperatures for cooking. Additionally, the heat retained by the black pot helps maintain a consistent cooking temperature, making the solar oven more effective.
Yes you can although it might not be as good as aluminum foil..
no of course you dont.
Concave mirrors are preferred in solar cookers because they can focus sunlight onto a single point, creating high temperatures for cooking. This concentrated heat allows for faster cooking times and more efficient use of solar energy. Convex mirrors, on the other hand, would scatter the sunlight rather than concentrating it.
Newspaper is used in a solar oven to help insulate and retain heat inside the oven, allowing for more efficient cooking. The paper acts as a barrier to prevent heat from escaping, enhancing the oven's ability to reach and maintain high temperatures for cooking food.
We use solar energy today for a variety of needs: Cooking food in a solar oven Converting to electricity to run appliances, cars and satellites Heating homes and offices Heating water for cooking, bathing, Swimming Pools, fish ponds Heating green houses to grow crops in the winter
Mirrors would make a better reflector in a solar oven as they have a higher reflectivity compared to tin foil. Mirrors can reflect more sunlight onto the cooking vessel, resulting in higher temperatures and more efficient cooking. Additionally, mirrors are more durable and long-lasting than tin foil.

If I had access to solar energy I would use more of it.
