<p>Perpetual motion machine. Engraving showing a design for a perpetual motion machine designed by Ulrich von Kranach in 1664. The device is driven by the cannonballs falling in the large wheel at right. These drop into a sloping curved track which feeds them into an archimedes screw. This screw, powered by the wheel, lifts the balls to the starting place. This is a variation of Fludd's water wheel of 1618. The problem with such designs is that they violate the first law of thermodynamics. To overcome friction in the system would require energy to be created out of nowhere. This illustration first appeared in the Gentleman's Magazine in 1747.</p>
