When Jon Bohmer sat down with his two little girls for a simple project they could work on together, he didn't realize they'd hit upon a solution to one of the world's biggest problems for just $5: A solar-powered oven.

Black paint on the inner box, and silver foil on the outer one, help concentrate the heat. (source: edition.cnn.com)
