The 3 types of Solar Cooker...

Source

The Panel Solar Cooker uses reflective panels to focus sunlight onto a pot. These work best in tropical climates or in the warmer months when wind and heat loss are not an issue. An inexpensive, aluminized cardboard panel cooker can heat food up to 250 degrees Fahrenheit. That is plenty since food starts to cook at 180 degrees F. Aluminum foil will work for a couple of weeks but after that the aluminum oxidizes and turns dark. The design shown (sold through Gaim $120) is made of polished aluminum and can heat foods to 350-400F on a sunny, warm day. Mo matter which type of solar cooker you use, always wear sunglasses!

Box Solar Cookers have an insulated box, topped with a transparent glass or plastic cover and a reflector or reflectors that help heat the box. Temperatures inside the box can reach 400 degrees F and cooking can be done almost unattended, like a slow cooker. This cooker is preferable to a parabolic if small children are around. The solar cooker box in the picture uses mylar on plastic flute board for the reflectors and the inside of the box is aluminum sheet metal. This model can be made at home. (See the youtube video at end of page.)

The Parabolic Solar Cooker (or Curved Concentrator solar cooker) concentrates the sun's heat onto the bottom or the sides of a pot -- similar to a stovetop. Temperature's can get so hot that you can fry food or pop popcorn. The advantages are speed and the potential to cook when it is cool outside. The disadvantages are safety concerns (as to eyes and children) and the need to stir the contents of the pot so the food does not stick, just like a stovetop. Temperatures can reach above 400 degrees Fahrenheit in the pot. The parabolic cooker might also need adjustment to keep it faced toward the sun.

Solar Cookers in Developing Countries...

Why= The World Health Organization has found that “indoor air pollution from solid fuel use is responsible for more than 1.6 million annual deaths and 2.7% of the global burden of disease." Plus, 45% of the world’s wood is used as fuel - which is becoming scarcer and scarcer.

I am trying to make a flat solar cooker with flat cardboard wrapped in aluminum foil and wires going all the way around the flat cooker and wires making an X, where the X meets i am trying to make a bowl made of just aluminum and i am going to set the bowl where the X meets. Do you think that it will actually cook a marshmallow or hersheys bar for a science experiment at school because i am not sure that it will work. I am afraid that i will get a bad graid on it. I need this question answered by tomorrow which would be May 3rd 2012. Thank you for reading this and hopefully you will answer my question on this website.Thank you bye, bye. please call 911 if you have any guestions.

I was impressed with the sheer variety of solar cookers displayed on your website, some of which I had never before seen. I am having so much fun with my new SunPower solar cooker so much that I made a YouTube video of it to share with others. You can see it by going to OneLightDancing.com. Feel free to add it to you impressive collection of solar cookers.
