2. Access to cooking
In developing countries, especially in rural areas, 2.5 billion people rely on biomass, such as fuel-wood, charcoal, agricultural waste and animal dung, to meet their energy needs for cooking. In many countries, these resources account for over 90% of household energy consumption.
As a result of indoor open fire cooking thick smoke fills the house causing a whole host of health and environmental problems for the families that live there
According to the World Health Organization, cooking on open fires is responsible for over 4 million deaths globally per year, which is more than AIDS and Malaria combined

4. Our sun
Our Sun is a constant source of energy. Each day, the sun bathes the Earth in unimaginable amounts of solar energy, most of which comes in the form of visible light. All over planet Earth, sunlight is the by far the most important source of energy for all living things. Without it, Earth would be lifeless.

5. Cooking with the sun
Sunlight can be a practical source of energy for such everyday jobs as cooking, heating water, or warming up homes. The challenge is to find ways to transform sunlight into useable heat. The most efficient way to transform sunlight into heat is to shine lots of sunlight onto a dark surface. Dark surfaces absorb most of the visible light that falls upon them, and reflect very little.
You are familiar with what happens to a dark-colored surface when sunlight strikes it: it will get warm. But without a little help, there is not usually not enough heat produced to cook foods. To produce enough heat for cooking, it is necessary to shine additional sunlight from a wider area onto the black surface. This is easy to do with mirrors or other reflective surfaces, or with glass or plastic lenses.

6. Solar Oven Safety
Use extreme caution when cutting cardboard, wood, or any other material with the utility knife. Extend the blade only as far as is needed to cut through the cardboard, and lock it into place. Do your cutting on a cutting board or piece of scrap plywood, cardboard, or a kitchen cutting board.
Use sunglasses when working with shiny materials in sunlight.
Solar ovens can get very hot! Use oven mitts or gloves to prevent burns.
Ensure you perform good housekeeping once you are done building your oven.
Take work very seriously and do not play or joke with sharp materials or chemicals.
