Solar Cooking
Solar cooking is not only fun but it's a great educational tool. Solar Box Cookers, constructed using cardboard, newspaper, aluminum foil, and a piece of glass will typically cook at temperatures between 225-275°F (107-135°C). It's a working model of the greenhouse effect.
It is a real oven, and will cook most anything you would put in your oven at home. They are considered a slow cooker, usually taking about twice as long as your conventional oven.
Put your food out early and you can run errands etc, and not worry about your home burning down, and the food can be left unattended for hours without fear of overcooking or burning.
Unlike your oven, the solar cooker does not add heat to the kitchen.
There's no need to rotate the oven to follow the sun, though it will improve cooking times.
You can take a solar oven to the beach or camping, and you can also use it to pasteurize water.
Panel Cookers require only one box, aluminum foil, a jar and an oven bag, and can be constructed in less than an hour.
