Solar Ovens, for Sunny People

Our church recently was offered space in a shipping container to send supplies to a town in New Sudan where we partner with a local pastor. Some of what we are sending are "Solar Ovens". While our church never described these in detail, they sounded interesting. CNN has up an article on the inventor of the Solar Oven which describes how it works. This seems like a great little invention that could revolutionize cooking in the developing world.
