Professor Jez Moonbeam, the man behind the semi-automatic toothpick dispenser, has come up with a device that he believes will revolutionise the lives of millions of office workers all around the world.

The Professor has taken the principal of potato printing to the next level by coming up with the 'chipwriter'. The machine works in much the same way as a traditional typewriter, except that it utilises a series of deep-fried potato chips, each embossed with a different letter or character. Moonbeam claims that the chip-writer can produce attractive, typewritten documents in a choice of green, orange or brown - thanks to special ribbons impregnated with mushy peas, baked beans or curry sauce.

He also working on a photocopier based on potato waffles.
