SUN OVEN is designed for large-scale feeding situations that require cooking great volumes of food quickly. Even though it is called an oven, enormous quantities of food can be boiled, steamed or baked at cooking temperatures of 500° F / 260° C with no fuel costs. The world has entered an era of increasingly higher energy costs. These costs are often viewed from an economic perspective, but the toll they take in human and environmental terms, while difficult to measure and often overlooked, are even more devastating. Feeding programs are often forced to choose between buying food or the fuel to cook it. SUN OVENS were developed to help feed large groups of people without destabilizing the environment or contributing to deforestation.
