Loaf-al warming?

Am currently very excited over an article a friend just sent me on solar ovens made from cardboard! This design, called the Kyoto Box, is composed simply of two cardboard boxes (one inside the other) with an acrylic cover that lets in solar rays. The box uses black paint and aluminum foil to concentrate the heat, making the temperature inside the box high enough to boil water (to make it safe to drink) or bake bread! The inventor, Jon Bohmer, (who just won the FT Climate Change Challenge), envisions the solar oven being used throughout Africa where people without electricity routinely burn wood and charcoal for fuel.

This is brilliant -- read the article here. Sign me up; I'm ready to buy one for our terrace!
