This project will never finish. Scroll down to see why. There are 11 gears. Once the gear before it completes a full rotation, it will turn one degree. Since the first gear turns a full rotation in approximately 12 seconds, the equation for finding when the last gear turns is 12 * 360^10 Or 4.38739e26 seconds. That equates to roughly 13,912,322,425,164,890,112 years.
