It beat many inventions, including ‘a food additive that stops cows from passing wind.’ Of course, it was more than a cardboard box— it was a solar oven. Able, according to Kyoto Energy (the company that made it), to boil water and bake bread by heating up to a maximum of 100°C.  There was a rough description on the site, and following the guidelines I made one myself. So far I have melted a piece of wax in it, but I will try baking cookies or something in it this weekend.
