A solar oven is a great way to conserve resources and tap into the wealth of energy that hits the Earth every day. In this Instructable, we will show you how to construct a high efficiency solar oven out of mostly waste or scrap parts you probably have lying around your house. The intention here is to use these materials that would normally take up space in landfills for harnessing the power of the sun. In this way, we are not only re-purposing and reducing waste, we are conserving resources.
Many people believe that these ovens are novelties and can not be used for anything. The truth is this oven heats up very fast and care should be taken when handing it or any contents when at operating temperature. Under spring weather conditions and when pointed properly at the sun on a clear day, it will pass 150°C (300°F) within 10 minutes.
