Sun Ovens International takes a different approach. We have taken a concept that has been around for centuries, and have combined it with more improved materials to make the most effective solar cooking devices in the world. The Sun Oven has been designed to overcome most of the cultural barriers that have restricted the widespread use of the sun for cooking. The initial price of a Sun Oven is higher, but due to its long life, ability to cook on partly cloudy days and allowing food to stay warm for hours, the cost per meal is lower than any other solar cooking device.
