This Tomato Soup Battery, created by Ben Woodeson, consists of a bathtub, copper and zinc electrodes, and a large amount of tomato soup. This electricity source apparently generates enough power to play video games on a black and white TV.
Whether or not this is a hoax, I have no idea, but the idea is so creative and silly, that if any kind of non-biological "food for energy" transformation can be made efficiently, a new business might be in the works.
