Parabolic Solar Oven

Mention solar power to someone and they immediately think of solar panels. A parabolic solar oven, however, has a much more practical use when it comes to feeding ourselves.
Parabolic Solar Oven
While searching for ways to reduce the use of nonrenewable resources, you might encounter solar power. Solar power, or solar energy, is the use of the sun's rays to either create energy (electricity), charge a battery, heat water or other fluids, passively heat homes through glass windows, or even cook foods. When solar power is used to cook food it's often in the form of a solar oven, which can be used in place of firewood and other fuels in order to cook meals. One popular type of solar oven is the parabolic solar oven, used over others for many reasons.
A parabolic solar oven collects the sun's rays by using a reflective surface in a parabola, or curved shape. There are many different styles of parabolic solar ovens available, and there are instructions available to create most of them. The parabolic style allows for food to cook at much the same rate as a conventional oven, making it more convenient than other outdoor cooking methods such as campfires. Additionally, since the parabolic solar oven doesn't use wood or other fuel, it's quicker to start cooking and requires little time to set up - whereas with a campfire, you've got to spend time hunting for firewood, as well as lighting the fire and waiting for it to get hot.
One easy way to start building your own parabolic solar oven is by using a ready-made satellite dish (of course, use one that someone has discarded). Its parabolic shape is perfect for creating the oven, and all you need to do is coat the inside with a reflective substance, such as a mirror finish reflective aluminum sheet. Other people prefer to start their parabolic solar oven with more of a bowl shape, as they believe this allows food inside to cook better and helps to shelter the food from the wind.
